Abstract: A torque support for the articulated mutual support of two elements is provided, for example, a frame or a bogie on the one hand and a housing such as a final drive housing of a rail vehicle on the other hand. The torque support includes a rod, at the two ends of which one respective receiver head is arranged. The receiver head includes a bearing for accommodating a bolt which is used for support on the respective element. The rod is arranged as a sleeve at least in the region of its two ends and the bearing includes a socket which is arranged in the radial direction of the bolt between the bolt and the receiver head and is supported on the receiver head via at least one further bearing element. The socket includes a bulbous section in the manner of a universal ball joint on its outer circumference.

Abstract: A drive unit for rail vehicles has a shaft including a hearing pin on each end for carrying a drive wheel, a supporting tube enclosing the shaft and journaled thereon, an engine mounted on a supporting tube, wherein the engine rests on a single bracket, the single bracket fastened to the supporting tube, a transmission including a spur wheel and a drive pinion, a housing enclosing a spur gear and the drive pinion, the housing including a single main part, a lid, and an engine bell, the engine bell forming a fixed connection between an engine housing and the main part of the housing, where the supporting tube is molded to the single main part of the housing to form a rigid unit and an engine rotor journaled on a single bearing, wherein the engine rotor is supported at a transmission side on a membrane coupling, the membrane coupling carried by a fully journaled drive pinion.

Abstract: A length-adjustable shaft comprises an outer sleeve-shaped axial part; an inner axial part which can be pushed into and deployed out of the outer axial part in a telescopic fashion and which encloses a buffer chamber; having a bearing which is arranged between the two axial parts and which can be lubricated with a lubricant; that end of the inner axial part which can be pushed into the outer axial part has an end wall; a ventilation opening is provided which connects, in a conducting fashion, the buffer chamber to the cavity which is enclosed by the outer axial part, and the ventilation opening comprises at least one bore which is offset with respect to the rotational axis of the shaft.

Abstract: The invention concerns a drive unit for rail vehicles, comprising the following components or characteristics: a shaft, a supporting tube, which encloses the shaft and is seated thereon; an engine, which is mounted on the supporting tube; a transmission having a spur wheel and a drive pinion; a housing, which encloses the spur wheel and the drive pinion; the housing consists of a single main part and of a lid; the engine rests on a single console, which is fastened to the supporting tube; the housing includes a engine bell, which forms a fixed connection between the engine housing and the main part of the housing; the supporting tube is moulded to the main part of the housing, so that both of them form a rigid unit together.

Abstract: The invention relates to a length-adjustable shaft comprising—an outer sleeve-shaped axial part; —an inner axial part which can be pushed into and deployed out of the outer axial part in a telescopic fashion and which encloses a buffer chamber; —having a bearing which is arranged between the two axial parts and which can be lubricated with a lubricant; —that end of the inner axial part which can be pushed into the outer axial part has an end wall; —a ventilation opening is provided which connects, in a conducting fashion, the buffer chamber to the cavity which is enclosed by the outer axial part. The invention is characterized by the following features: the ventilation opening comprises at least one bore which is offset with respect to the rotational axis of the shaft.
