Abstract: In an articulated combine, front and rear bogies are connected by spaced-apart upper and lower links. The upper link permits relative lateral movement between the bogies due to oscillation about a longitudinal axis. At the lower link, a rigid tongue of the rear bogie is connected to the front bogie by a ball hitch. Steering of the vehicle is through a pair of hydraulic cylinders controlled in part by a feedback cylinder. The steering cylinders are connected together to the rear bogie, at a common ball joint. All other connections of the hydraulic cylinders are ball and socket type and their effective pivot centers define respective transverse (kneel) and longitudinal (oscillation) axes, intersecting at the ball hitch. Forward connections of the steering cylinders and one end of the feedback cylinder lie on the kneel axis. The common rearward steering cylinder connection and the connection of the other end of the feedback cylinder lie on the oscillation axis. This arrangement isolates the steering system from oscillation and tipping movement of one bogie relative to the other in the sense that such movement, by itself, does not directly impose length changes or axial loading in the steering system cylinders.

Abstract: Apparatus for cutting thin laminae of stone, e.g. marble, comprising a saw having two disc blades, a bogie movable beneath the saw and having a pair of vacuum-operated slab-gripping devices each of which is adapted to support a slab upwardly on its edge, and a second bogie movable in a direction transverse to the first bogie and carrying structure for tumbling a slab supported on one longitudinal edge, through 180°, so that it rests on its opposite longitudinal edge.

Abstract: A railway bogie is disclosed with wheels of high effective conicity and supported on the wheels through pads with low yaw constraint so that they are self-steering. Cross-members connecting diagonally opposed wheels interconnect yawing movements of the wheelset in opposite senses to counteract the tendency to hunt. Wheels on the same side of the bogie are connected by links pivoted on a lever pivoted on the bogie frame at one end and on the bearings of the wheelsets at the other end. This interconnection inhibits the bogies frame from moving longitudinally when braking or traction forces are present and ensures that yawing movements of the frame are effectively transmitted through the wheelsets and then to the wheel/rail contact area.

Abstract: Tractor bogie suspension with steering and weight transfer control, effective to pitch such a front-steered machine as to convert from a non-all-wheel drive, three axle operation to an all-wheel-drive, two axle operation, doing so both automatically and on the go.

Abstract: The present invention is directed to an assembly for stabilizing a vehicle supported on at least three pairs of wheels or tracks, wherein various pairs of wheels are selectively connected to one another in bogie style so as to reduce tipping movement of the vehicle chassis as the wheels travel over uneven terrain. A second embodiment of the invention discloses means to control the bogies with respect to their direction of rotative movement. Fluid damping means are provided for some or all of the wheels. These damping means are interconnected with longitudinal and diagonal conduits, with pumps and valves placed to control the movement of the fluid medium between the respective damping means.

Abstract: This invention relates to a track unit intended for endless tracked cross-country vehicles, for example forestry working machines, comprising at least one driven track driven from a driven axle of the vehicle. In order to render possible the driving of forestry working machines with tracks of rubber, which are much more sparing for the ground than steel tracks, but do not possess the tensile strength of steel tracks, the present track unit of bogie type distributes the driving force on several tracks and comprises two track stands (9), each of which comprises a track (8) supported on two wheels (38,39) and driven via of these wheels (38,39), which track stands (9) are mounted between the axles (40,41) of their wheels each at one end of a rocker arm (5), which in its turn is located freely pivotally between its ends on the drive axle (4) of the vehicle, between which drive axle and the drive wheel axle (40) of each track stand a chain transmission (12,13,14,37) is located.

Abstract: The invention relates to a pneumatic suspension bogie with radially adjustable wheel sets. The radial adjustability of the wheel sets serves to reduce the wear of the wheel flange. This is achieved by means of wheel sets (4) which can be rotated in the longitudinal central plane of the bogie about vertical axles, the wheel sets being mounted in U-shaped brackets (11) and the latter being connected in turn to one another in the longitudinal direction by means of connecting element (12). In order to synchronise the rotational movement of the wheel sets (4), the brackets (11) are connected to one another in the external region via levers (14a and 14b), the levers being connected to the bogie frame (1) in a rotatable fashion by means of pivot pins (15a and 15b). In order to control the wheel sets (4) actively, the levers (14a and 14b) are coupled to a hydraulic piston-cylinder unit (16) which is acted on by means of a control unit (18), the control unit (18) being controlled by the play between wheel flange and an inner edge of the rail. In Fig. 2, an exemplary embodiment of the bogie with active control is illustrated.

Abstract: A bogie for a self-propelled railway car comprises a brake for at least two wheel sets, the axle of one of which can be driven by an electric motor through a gear train. According to the invention, not only is the support frame mounted upon a pin depending from the vehicle chassis and a secondary spring suspension provided between this frame and the chassis, but the pin also carries at least part of the weight of the motor and drive train and/or the brake system. Both the drive train and the brake system are connected to the driven axle by a universal joint shaft arrangement and a primary suspension is provided between the axles and the frame.

Abstract: A terrain-traveling motor vehicle (1) has twin caterpillar tracks and bogie assemblies (2) pivotally attached to the frame (3) of the vehicle, comprising a rear pair of drive wheels (5) mounted on the frame (3) of the vehicle and a pair of front wheels (7) each of which is supported on a pivotable belt-tensioning arm (9) disposed on the forward end of a bogie arm (8) found on each bogie assembly (2). The rearward end of the bogie arm (8) is supported by shaft journals (4) proximate to and in front of the center axis of the pair of rear wheels (5). The bogie arms (8) are movable in the vertical plane by hydraulic pressure cylinders (6) controllable from the cab of the vehicle for upward and downward pivoting of the bogie assemblies simultaneously or independently of each other, and for tautening the bogie tracks. The belt-tensioning arms (9) are movable independently of the bogie arms (8) by means of respective hydraulic pressure cylinders (10) which are pressurized at a desired adjustable pressure for maintaining a desired tautness in the belt during the pivoting movement of the bogie arm (8), as well as during the continual changes in the configuration of the lower perimeter of the belt which arise as the track passes over irregular ground terrain.

Abstract: In an articulated combine, the hinge arrangement connecting the front and rear bogies consists of spaced-apart upper and lower links. The lower link construction provides for oscillation between the bogies as well as establishing a steering pivot center. The upper link normally lies in a fore-and-aft plane and is pivotally connected between rearward upper portions of the respective bogies, thus spanning the length of the rear bogie. The hinge arrangement also provides part of the structure for a conveyor for conveying clean grain between the front and rear bogies. In one embodiment, the upper link comprises an auger tube into which clean grain is introduced by a clean grain elevator and cross auger. In another embodiment, the lower link assembly does double duty as an auger conveyor housing.

Abstract: Device for ensuring the vertical suspension of the chassis of a bogie and the longitudinal and transverse coupling of each box of the chassis in a driving or carrying railway bogie, comprising a vertical suspension spring through which the bogie frame is supported on the axle box, thereby creating a rotary torque on this box, and including two flexible couplings mounted spaced in altitude between the frame and the axle box so as to be compressed when the axle box tends to rotate under the effect of the rotary torque. The rotary torque is provided by two suspension springs of helicoidal spring type which are mounted on each side of the vertical plane passing through the axis of the axle, and by the fact that each vertical coupling is constituted by at least one elastic stud forming a monoblock whose terminal cross-sections are fixed to a support surface of the bogie frame and to a support surface of the axle box, so that the compressive force due to the suspension springs results in low shear strength in the vertical direction.

Abstract: The in-situ milling of rail heads of rails 14 is effected by a device having at least one driven rotating milling head (2) with at least one milling cutter head drive (3) mounted on a bogie frame 16 which has guide shoes (4) which can be selectively raised and lowered and are arranged ahead of and behind the milling head (2) with of reference to the direction of travel Lateral guide rollers (5) are provided which engage the side of the rail head (15) of a rail (14) to be machined The milling cutter head (2) may have as many cutting edges or tools (21,22,23,24) (not shown) as the number of partial arcs to be milled and two milling units each having a milling head (2) and a milling head drive (3) can be provided for the simultaneous machining of the two rails (14) the two milling cutter housings (1) being connected to one another by means of (6) with gauge tolerance adjusting means (7, 20) The milling cutter housings may be arranged on pivotal supports (25, 26) connected to a swivel beam or bar (11) of a bogie (17) by way of link pins (12) The device can be in the form of a self-propelled unit or a unit which is drawn, by a locomotive

Abstract: The self-propelled high-speed rail vehicle comprises one or more enclosed passenger cabins (1), preferably without wheels, mounted between and supported by two travel bogies (2,3). One or both the bogies have one or more driving motors (10) or engines. There can be a free space between the bottom of the cabin and the rails, the clear distance between them being no more than 0.6 metres, and preferably between 0.15 and 0.3 metres. Ballast weights, preferably of steel, lead or spent uranium, can be mounted below the cabin floor.

Abstract: The invention relates to a control for the joint of four-axled rail vehicles, in which the two carriage bodies (2, 2a) are mounted on one bogie (13b, 13a) in each case and are connected in their centre by means of a joint (12). Since this joint (12) requires a control so as not to migrate inadmissibly when going round bends, it is proposed according to the invention that the secondary springs be constructed as solid-rubber or flexicoil springs since the latter exert a torque on the carriage body (2a) via the front bogie (13a), whilst by means of the secondary springs of the following bogie (13b), restoring moments are exerted on the wagon body (2), so that the position of the joint (12) is automatically set in the desired manner due to balancing of the moments when the tension in the secondary springs is released.

Abstract: A portal (1) for removing and laying railway tracks (3), particularly points, allows the period of interruption of the railway and the work force used to be drastically reduced. The portal (1) has a crossbeam (4) with ends slidable vertically along respective pillars (5). Each of the pillars (5) is provided with tracks (8). The crossbeam (4) includes a central section (12) and end sections (13) which can be individually extended from the central section (12). The central section (12) is mounted on a railway bogie (16) with the interpositioning of a turntable (17), the bogie (16) having withdrawable, retractable wheels (18).

Abstract: The semi trailer (1) has a drawbar (10) pivoting at the front of the trailer platform. There are at least two pairs of wheels (3,4) with one pair (4) steerable. There is a transmission (12,13) between the drawbar and the steerable wheels. This works so that when the drawbar pivots the transmission turns the wheels appropriately. The two pairs of wheels are mounted on bogies (2). The steerable wheels are opposite to the drawbar relative to the non steerable wheels. The transmission turns the wheels opposite to the drawbar rotation and is hydraulic and includes rams (12).

Abstract: This automotive rail vehicle is characterised by a special frame construction with folding down buffer beams and lifting platforms which are arranged over the bogies and permit the large pallets which are deposited above the rail element, for example in steel works and iron foundries to be travelled under, raised and transported. The lifting platforms which are arranged displaceably in swivel frames also permit the large pallets to be set down and picked up on both sides of the rail element in that the swivel frames are swivelled through 90 DEG transversely with respect to the longitudinal axis of the vehicle and are secured at their ends by means of folding-out sustainers. The pallet can be moved on these swivel frames by means of the displaceable lifting platforms parallel to the rail element and set down next to the track. The boundary lines of the vehicle both in top view, side view and in front view lie within the dimensions or within the clearance of the spaces between the pallet sustainers. As a result, it is possible with this rail vehicle to store large pallets closely next to one another and one behind the other and above the rail element without additional loading and lifting devices at any desired site and to pick them up again.

Abstract: PURPOSE:To ensure coil handling and automate a coil yard by providing a pallet position detector and a pallet snatch mechanism on an elevator bogie suspended from a trolley bogie by use of an hoisting mechanism. CONSTITUTION:As an elevator bogie 5 is rapidly wound downward, a detection rod 13 gets into contact with the uppermost pallet 21 when the elevator bogie 5 reaches a certain height above the pallet 21, and it rises through a pallet snatch guide 10 in response to lowering of the elevator bogie 5, activating a lowering deceleration position sensor 14 and a stop position sensor 15 in sequence, therefore a driving unit 7A of a hoisting drum decelerates the lowering speed at a deceleration command from the sensor 14 and stops it at a stop command from the sensor 15. Then, the pallet 21 is introduced between the lower sections of the guide 10, is correctly positioned by locating stoppers 11, and is snatched by a snatch lever 16.

Abstract: The running gear is for a rail vehicle, whose chassis or bogie is supported on the axle boxes so as to allow horizontal movement by means of horizontal links. These links (7-10) are at an angle (a) to the lengthwise direction of the vehicle, and couple the axle boxes (3-6) to an inert mass (11) movable in the transverse direction. This mass can be formed by the frame of a two-axle bogie, or alternatively can be an additional one in turn attached by horizontal parallel links to the vehicle underframe.

Abstract: The transmission system is for a monomotor bogie with two right angled gearboxes (P1,P2), one on each axle (1,2). There is a third single reduction gearbox (Po), integral with the traction motor (M). This drives an intermediate shaft (3) joined to two input shafts (11,12) to the other right angled gearboxes. The right angled gearboxes are single reduction type. The third gearbox (Po) is also single reduction and gives a right angled drive. The traction motor is parallel to the axles. It shares a common lubricating system with the third gearbox. The intermediate shaft can isolate the motor from the axles.

Abstract: PURPOSE:To manufacture a machine for correctly cutting or removing beads on the inner surface of a pipe, by arranging a supporting mechanism having an extendable pole at each of the front and the rear of a bogie insertable into a pipe and providing cutters and positioning rollers on a rotary disk driven by a motor mounted on the bogie. CONSTITUTION:At the front and the rear of a bogie 2 insertable into a synthetic resin made pipe 1, supporting mechanisms 3a, 3b provided with extendable poles 4 of more than three at the regular interval and radially are formed. On a rotary disk 8 driven by a motor 5 mounted on the bogie 2, a support member 9 movable radially is attached and a blade 10 and a positioning roller 11 are provided at the end of the member 9. The whole mechanism is entered into a pipe with the poles 4 contracted, and the poles are extended at a position of the beads to contact with an end shoe 21 with the pipe inner face and to apply the blade 10 at the center of the bead. Then beads are removed by driving the motor 5.

Abstract: Portable working device for supporting and guiding a working tool, particularly a welding or burning torch. The device has a bogie with a single tube-like axle, the supporting traveling wheels of which are magnets with pole shoes with independent drives. The holder of the working tool is fixed to an arm slidingly arranged within the bogie axle. Since the force maintaining the bogie wheels is magnetic when the workpiece is ferromagnetic, the device is of relatively low weight and is capable of operating in any position. As no part of the device extends beyond the diameter of the supporting traveling wheels, its working range is very extensive.

Abstract: The bogie for a railway vehicle travelling at high speeds, has an H shaped frame between two axles. This consists of two longitudinals (7,8) each supporting two wheels for one rail, connected by a tube (9). Each longitudinal is a channel, with a deep central web, of a size sufficient for the tube to pass through it. To allow each longitudinal to tilt independently, about the axis of the tube, the tube is in two sections with two bearings (12,13) between. A short tube section passes through the web of one longitudinal (8) and the other tube (9) through the other web, passes through this short section, with the bearings between.
