摘要:
The rail car (1) with a substructure (2) and a car body (3) arranged thereon having a main suspension system (4) on a fluid basis is provided with at least one strut (5) supporting the car body (3) against the substructure (2). The pressure prevailing in the strut being correlated to the weight of the car body, and at least one emergency spring (6) supports the car body (3) against the substructure (2) in case of a failure of the main suspension (4). The at least one emergency spring (6) is biased and maintained in normal operation position (FIGS. 1, 2) by a force (F) generated by the pressure (p) prevailing in the strut (5). The emergency spring (6) expands from the normal operation position into an emergency operation position (FIG. 3) in which it resiliently supports the car body (3) in case of a failure of the main suspension system (4).

Disclosed is a railway vehicle comprising at least one pneumatic spring for supporting a body. At least one mechanically actuated valve is disposed in at least one air supply/discharge tube of the at least one pneumatic spring in order to control air exchange of the at least one pneumatic spring. At least one switching means is provided between the at least one mechanical valve and the at least one pneumatic spring in the at least one air supply/discharge tube in order to control air exchange. Alternatively, at least one switching means is arranged between the at least one mechanical valve and at least one pressure source while at least one additional switching means is placed in a tube that connects the at least one mechanical valve to an environment in order to control air exchange.

A traction vehicle, in particular railway traction vehicle, comprising a bogey chassis mounted on wheel axles, a vehicle chassis spring-mounted on the bogey chassis and at least one motor-transmission unit mounted underneath the vehicle chassis and within the bogey chassis close to the wheel axle driven by the motor-transmission unit. The motor-transmission unit is suspended from the bogey chassis by a pendulum suspension close to the set of wheels in the bogey chassis. The motor-transmission unit is also suspended in the vehicle by a pendulum suspension. The motor transmission unit is provided with a pair of connecting rods in which either or both are connected to the bogey chassis or the vehicle chassis. The connecting rods are arranged with one rod parallel to the longitudinal axis of the vehicle and the other rod being either parallel to or angularly related to the longitudinal axis of the vehicle.

A chassis frame for rail vehicles includes two longitudinal beams and at least one transverse beam which is disposed between the longitudinal beams and hinged thereto. The longitudinal beams are designed in a bent shape and extend through a corresponding cutout of the transverse beam.
摘要:
A primary spring for chassis of rail vehicles is provided. The spring is designed as a substantially rectangular layered spring that is fitted into a bearing housing.

The present invention pertains to a truck frame for railway rolling stock with a two-axle undercarriage secured by means of a primary suspension to a frame on which, through the intermediate setting (28, 29) of a secondary suspension, a hinged bracket (30) is mounted, transversally oriented relative to the direction of movement, said hinged bracket (30) being attached through oscillation about an axle oriented longitudinally relative to the car to an inclinable cross-bar bearing the car body. This cross-bar is designed as a frame and has two crossbearers (46, 47) mounted prior to or past the hinged bracket (30), while the crossbearers (46, 47) take their bearing against the hinged bracket in direction of movement and are mounted transversally mobile relative to direction of movement. Furthermore, the crossbar has preferably a central segment (50, 51, 52) connected to the frame (2) of the undercarriage to absorb the longitudinal forces through a guide in the form of a lemniscate, so that the cross-bar (31) can rotate about a substantially vertical axis and hinge in a substantially transversal plane relative to the direction of movement.

The invention relates to a brake installation for railborne vehicles comprising at least one wheel axle driven by a coupled motor-transmission unit in which the unit is connected by directly meshing gears for driving the wheel axle in a manner avoiding an intermediate gear, preferably by way of a hollow shaft concentrically enveloping the wheel axis. The wheel axle or the hollow shaft is connected to a disc brake shaft by directly meshing gears, without intermediate gears for transmitting a driving force to a disc brake provided on that side of the wheel axle which is opposite to the unit, wherein the brake disc is fitted on a brake shaft arranged parallel to the wheel set axle and to the motor shaft mounted on two sides to the motor-transmission unit.
