Abstract: A system for suspending the traction motor and gear box of a parallel drive arrangement in a railway truck or the like in which the gear box and traction motor shafts are flexibly coupled together to accommodate relative movement between the two shafts. In addition, an arrangement is provided by which the mounting of the motor on the railway truck accommodates lateral displacement while the coupling between the traction motor housing and the gear box accommodates angular and offset misalignment of the coupled shafts.

Abstract: Universally mounted wheelset where an axle housing suspension utilizes a rocking hinge principle to absorb shocks with limited up and down movement. A pair of swivel blocks are connected by trunnions to fore and aft ends of the axle assembly enabling rocking movement of the axle assembly about a longitudinal axis extending generally longitudinally of the direction of movement of the vehicle. One of the swivel blocks is hinged to the vehicle frame. This enables the axle housing to tilt up and down about the hinged swivel block in addition to rocking about the longitudinal axis. Cushioning springs are provided between the vehicle frame and the opposite, tiltable end of the axle assembly.

Abstract: A bogie arrangement for self-propelled high-speed rail vehicles with at least two driving bogies supporting the vehicle body. Each of the driving bogies is powered by at least one electric motor and supports the vehicle body by a spring system while having a common pivot point with the vehicle body. The rotor of the fully spring-cushioned and transversely extending motor is operatively connected to the driving wheel set through the intervention of a transmission and a cardan quill shaft having elastic articulated bearings. The motor is held in the space between the wheel set axle and the vertical central transverse plane of the bogie transversely swingably on the understructure of the vehicle body. The longitudinally acting forces of the motor are transmitted by at least one link of considerable length from the housing of the motor to the adjacent frame section of the vehicle.

Abstract: The drive means for each wheel set is connected via a two bar-like connecting member to an intermediate portion of the bogie frame or to a cross-member in a manner such that longitudinal forces are transferred to the vehicle body. Also, the opposite side of the drive means is mounted on an axle of the wheel set and is connected to the bogie frame in a manner so as to permit the transmission of transverse forces to the bogie frame.

Abstract: A railway car includes a chassis supported on two sub-frames which are relatively pivotally movable. The sub-frames support propulsion motors, differentials, and driven flanged wheels. And intermediate steering axle and wheel assembly are transversly movable in response to track curvature and a steering beam extending outwardly from the steering axle pivots the sub-frames for steering movement.

Abstract: A driving bogie having at least one driving motor, a pair of driven wheel-and-axle units and an axle gear for each of the axles of the wheel-and-axle units rigidly connected with the bogie frame, is arranged with a hollow transmission shaft for the axle gear encircling the axle of a respective wheel-and-axle unit and with a hollow Cardan shaft rigidly connecting the hollow transmission shaft with the wheel-and-axle units through centering articulated couplings. The invention is particularly directed to the structure of the articulated couplings which are formed with a number of hinged levers and with ball joints at the ends of each of the levers, the number of the hinged levers being an even number greater than three, with half of the hinged levers being arranged in the direction of rotation of the coupling and with the other half of the hinged levers being arranged in the opposite direction.

Abstract: A drive for a railway track-bound propulsion vehicle includes a traction motor with output shafts on both sides. The motor is longitudinally arranged between two driving axles of a track-bound propulsion vehicle and is designed without a housing. In addition, the drive pinions are arranged directly on the rotor shaft which is supported in bearings in the transmission housing which also supports the stator of the traction motor. To take up the thermal expansion due to the different temperature rise of the stator and the rotor, at least one centering coupling which permits longitudinal displacement is provided in the train of the rotor shaft.

Abstract: A six-wheel railway motor truck for swivelly supporting a locomotive body is connected to the same for the effective transmission thereto of draft and braking forces at a level at or near that of the rail whereby the vertical moment arm through which traction forces might act to tip the truck frame and thereby cause load transference from axle to axle is minimized, with corresponding minimization of such load transference. The truck comprises a rigid frame resiliently supported on the three axles, a body support bolster supported on the sides of the truck frame by upright springs and held against swivelling movements or longitudinal movements with respect to the truck frame while being free for limited vertical and transverse movements with respect to the truck frame.

Abstract: An axle housing has a longitudinal pivotal connection to the frame enabling it to rock about an axis extending generally longitudinally of the direction of movement of the vehicle. One of the fore and aft sides of the axle housing has a transverse pivotal connection to the frame enabling the axle housing to tilt up and down, in addition to rocking about the longitudinal pivotal connection. Spring means support the frame at the opposite side of the axle housing. The combination of rocking about the longitudinal pivotal connection, and up and down tilting about the transverse pivotal connection, absorbs shocks due to irregularities in the track or ground. The invention is applicable to non-railway vehicles, as well as the railway-type vehicles shown.

Abstract: A two-axle motor driven railway locomotive truck having a large low positioned center plate supported on a transverse bolster mounted low between the axles and carried on the truck frame by a four element focalized elastomeric secondary suspension which also transmits driving and braking forces. Elastomeric support pads are positioned low with effective compression load lines intersecting at rail height and forming obtuse included angles to substantially eliminate weight transfer effects and provide much higher stiffness in the longitudinal driving and vertical support directions than for lateral movements and fore-and-aft pitching motions between the frame and bolster. These effects combine with a soft primary spring suspension of the truck frame on the axle journals to provide low weight transfer for high adhesion performance and maintain good wheel load equalization when negotiating vertical rail irregularities, while eliminating wearing load carrying surfaces between the bolster and the truck frame.

Abstract: Railway three-axle, three-motor locomotive trucks are provided with a bolster spring-supported on the truck frame for lateral and vertical movement and having a central opening to accommodate the middle axle motor while minimizing the over-all height of the truck, a plurality of vertically nonyielding body-support bearing elements on the bolster spaced apart transversely and longitudinally of the truck to prevent tipping of the bolster relative to the body, a swivel connection between the body on the bolster, and a draft connection between the bolster and truck frame at a level at least as low as the axles to provide low-level transmission of traction forces between the truck frame and bolster and thereby reduce axle-to-axle load transference and thereby improve adhesion.

The secondary suspension comprises three laminated metal and rubber pads positioned between the upper surface of the truck frame and the locomotive chassis. Two of the pads are positioned forwardly of the central axle of the three axles, and to a respective side of the central longitudinal axis of the truck frame. The other pad is positioned on the central longitudinal axis rearwardly of the central axle.

Abstract: This application discloses a railway vehicle truck of a general configuration having independently movable side frames, wherein the side frames are provided with resilient connections with the wheel-axle units which allow universal turning movement but substantially inhibit relative axial movement; wherein the side frames are connected at longitudinally spaced points by transverse cross-frame or transom bar members which are rigidly connected to the side frames at one end and connected to opposite side frames by true turning shaft-bearing joints which also, when needed, provide limited axial movement, the shaft-bearing joints having axes disposed on a line passing through the vertical axis of turning of the truck whereby the transom bars positively maintain the truck in tram; wherein a center frame is mounted at longitudinally spaced laterally central points on the transom bars by resilient joints which are spaced approximately the same distance from the transverse vertical central plane of the truck as the s

Abstract: A spring element comprises an insert formed of a rigid metallic core having four outwardly directed faces each bonded to a respective side of a respective elastomeric body whose other side is bonded to a respective metallic plate. The insert so formed is compressed and fits in a throughgoing central passage in a rigid metallic casing with each of the metal plates pressing against a respective inwardly directed face of the casing. The insert is symmetrical about a vertical plane and the angle between the upper two bodies can be larger than the angle between the lower two bodies. In addition the metal plates of the upper two bodies may be integrally formed of a single metal strip also constituting a part of the casing and the lower bodies carry metal plates which lie within a seat which can be formed in a motor-vehicle frame element for a very compact assembly.

Abstract: A rail vehicle, especially a passenger train car for high-speed trains provided with air springs associated with each swivel truck in symmetry with the longitudinal central plane, their distance from center to center being so much smaller than the track gauge of the wheels that, if one air spring bellows fails, the weight of the car body will be distributed to the wheels in such a manner that the unloading of the wheels on the one side will not be such as to create the danger of derailment. To stabilize the car body the latter is joined to the swivel truck frame by a resilient linkage which permits vertical movements of the car body but opposes any lateral tilt of the car body by means of a resilient force. The resilient linkage is able to cause the car body to tilt towards the inside of curves when the car is negotiating curves. The swivel truck can be designed either as a driving or as a non-driving truck.
