Bogie for rail vehicles such as tramways with the half bogies (4) swivelling horizontally on the crossmember (1) by vertical pivots (2) and connected to each other by tie rods (7) in which half bogies the vertically resilient runner wheels (9) are driven through one angular gear each (14) movable with them and independent of the opposite runner wheels (9) characterized in that the crossmember (1) is connected to the half bogies (4) by the pivots (2) in the manner of a universal joint, and rests on them by means of spring elements (8) arranged on either side of the pivots (2), and in that a single motor (15) is arranged on each half bogie (4) laterally between the angular gears (14) whereby the motor (15) has an internal rotor (15a) and an external rotor (15b) which run in opposite direction and are mounted on extended pinion shafts (16) of the angular gears (14) in a cantilever fashion.

Abstract: 1. A four-axle bogie for low-platform vehicles, comprising two H-shaped frames (5), each of which carries two wheel-and-axle sets (11) and which are articulatedly connected to a main carrier (1), which constitutes a crossbeam (2) and receives the swivel bearing (3) of the bogie, characterized in that the superstructure of the vehicle is mounted on the crossbeam (2) by means of a depending pin, which is rigidly secured to the superstructure that each of these ends of the side members (8) of the H-shaped frames (5) which face the crossbeam (2) is pivoted to the crossbeam (2) on a horizontal axis (6) directly or with an interposed two-armed lever (4), and that the superstructure of the vehicle is secured to each side member (8) by means of a carrying spring (15).

Abstract: An improved suspension assembly for a seismic exploration vehicle having a substantially rigid main frame supported and moved by track assemblies disposed along opposing sides of the frame. The suspension assembly includes two bogies which engage the inner periphery of a track on one side of the vehicle and each of the two bogies is mounted on one end of a bogie arm that is pivotally connected, at the other end of the bogie arm, to a central portion of a walking beam pivotally connected to the vehicle frame. End portions of the walking beam overlay the distal ends of the bogie arms and air bags are mounted between the distal ends of the bogie arms and the ends of the walking beam to bias the bogie arms in a downward direction.

Abstract: The system is designed for easy loading and unloading of deep-loader wagons for carrying road vehicles and large containers on railways. The loading surface on which travel is possible is swung round symmetrically to the longitudinal axis of the train and is brought into effective contact with a loading and unloading ramp at the end sections. On the wagon, the deep-loading deck (10) linking the bogie frames (2,3) pref. has a base plate (12), acting as a loading plate, lying deeper than the frame mounting plate (7), with a drive for swivelling. The wagon may have standard dia. wheels and may be loaded and unloaded from the side.

Abstract: The axle control which serves to steer wheel axles (35, 36) in bogies has a control lever (23) which is connected to the vehicle frame (21) and the bogie frame (25) in an articulated fashion and which bears an eccentric cam (26). The eccentric cam (26) actuates two lever transmissions (27, 28) which guide virtually rigidly on a straight section of track and steer in a progressively increasing fashion on a curved section of track with increasing curvature, and are connected to the steerable wheel axles (35, 36) in an articulated fashion. As a result, on a curved section of track the friction between wheels and rails is reduced without the hunting motion of the rail vehicle on a straight section of track increasing.

Abstract: A bogie truck car body support system wherein a car body is directly supported on a truck frame by bolster springs, the system including a link arranged longitudinally of the car body and connected at one end to a link support which is fixed to the car body by a play-free shock absorber and at the other end to a pin through a play-free shock absorber and a bush rotatably fitted on the pin. The car body has neither the bush nor center pin directly connected thereto which might become wobbly. The system can be readily assembled and disassembled and is capable of reducing vibration and noise transmitted from the truck to the car body.

Abstract: With this support, the wagon body (1) is to be supported in a suspended fashion on the bogie (2) without impairing the running of the wagon even in the case of relatively large relative movements between bogie and wagon body. Two helical springs (3, 4) which extend concentrically with respect to one another are arranged between the wagon body (1) and the bogie (2) with intermediate elastic spring plates (5). The elastic spring plates (5) are arranged in the manner of ball-and-socket joints, a cup (8) made of elastic material being arranged between a spherical section-shaped first part (6) and a hollow spherical section-shaped second part (7). When the wagon body (1) rotates with respect to the bogie (2), the spring axle adopts an oblique position, the spring plates (5) exerting a joint-function so that the helical springs (3, 4) are stressed less by transverse forces and optimum running of the wagon from the oscillation point of view is ensured.

Abstract: Ladle bogie for the transport of molten metal and for weighing it has an L-shaped upper part on which the ladle rests and which can be tilted by a power cylinder drive In the position of rest, the upper part is supported on the lower part together with the ladle through a load cell system whilst there is adequate bearing clearance in the pivot of the upper part This clearance is taken up as soon as the tilting process begins This reduces the deadweight to a min so that the weighing accuracy which is affected by the deadweight-to-useful load ratio is improved The new ladle bogie has a simple design

Abstract: Secondary sprung suspension, between body and bogie frame has one or more springs in each longitudinal side area, supported on the body and indirectly connected to the bogie frame, on a vehicle travelling on rails. The spring is hinged to the bogie frame via a straight guiding system made up from levers. This is pref. in the form of a Roberts triangular guide-rod unit, with two arms of a triangular lever hinge-connected with a lever mounted on the bogie frame. Simple construction improves vehicle running, and reduces wheel and rail wear.

Abstract: of EP00406801. A tracking gauge of a wheel set of a bogie for rail or track vehicles whose wheels, having profiled rolling surfaces, are, for the active setting of a differential rotational speed, rotatably mounted on a common axle shaft (1) and are connected to one another by way of a controllable force-locking coupling (6), in which also, during motion, slipage is adjustable, characterised in that associated with the coupling (6) is a control (amplifier 8) which, by reason of supplied values of the vehicle speed (v), takes into account a stabilising coupling moment constituent inversely proportional thereto or, by reason of supplied values of the effective track curve radius (R) takes into account a guiding coupling moment constituent inversely proportional thereto, or conjointly takes into account these two moment constituents.

Abstract: PURPOSE:To obtain high reliable performance monitor by a method wherein the detected operation state value is judged as effective for monitoring of the performance only when the rate of change in the operation state value relative to the bogie value locates within a predetermined value. CONSTITUTION:Each data such as pressure P1-P7, temperature T1-T7 and T1'-T4', flow rate F0 and output L detected by detectors 9-12 is input to a decision unit. Arithmetic units 25, 43 calculate the bogie value used as a reference for checking the suitability of the detected data. An arithmetic unit 27 calculates the differences between two inputs among the detected data and the bogie values set by a setting unit 26. The calculated result is forwarded to a next comparator 28 and compared with the deviation bogie value stored in a memory 30, thereafter the obtained result being applied to a decision unit 29. When the two values calculated by the arithmetic unit 27 are smaller than the deviation bogie value, the detected data is input to an arithmetic unit 33 and then applied to a heat rate calculating unit 8 via a setting unit 34. In case of one input, the detected data is input through a circuit including a setting unit 41.

Abstract: PURPOSE:To make the layout of a pair of upper and lower conveyors with different chain pitches mechanically synchronous by giving an inner course to a conveyor of a low speed at a U-turn part to improve the difference of moved distances for a synchronous operation. CONSTITUTION:An electric source device 5 and a conveyor bogie 8 are set to keep a fixed positional relation in an endless conveyor circuit 12 by selecting intermediate points A and B of a going way 13 and returning way 14 for synchronization points. When the electric source device 5 of a low speed and the conveyor bogie 8 of a high speed are moved on the going way 13 as an arrow 17 shows from the synchronization point A to reach to the end of the going way 13, the moved length L of the conveyor bogie 8 is longer than the moved length l of the electric source device 5 by a difference (d). Therefore, the electric source device 5 is devised to take an inner course for making a U-turn so that the electric source device 5 may be antecedent to the conveyor bogie 8 by d as they reach to the starting part of the returning way 14 via respective U-turn parts 15 and 16.

Abstract: Means are described for bogie mounting a roller (94) to an idler (88) on a crawler track undercarriage (10) such that the benefits of load transfer and shock absorbance are provided for a single roller-idler combination on a tracked vehicle. A tracked undercarriage (10) has a track frame (12) to which is pivotally mounted a support link (34), and pivotally mounted thereto a bogie link (60). Rotatably mounted on the bogie link (60) are an idler (88) and a roller (94). Variations in ground level cause the bogie link (60) to rotate such that resilient pads (98, 106) are compressed thereby absorbing shock and so that the roller (94) is less heavily loaded and the idler (8 8 ) has its loading increased.
