Abstract: 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).

Abstract: 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.

Abstract: 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.
