Lateral support element, gas spring assembly and method
A lateral support element (304) include an element wall with a first surface facing away from an associated flexible wall (264) and a second surface facing toward the associated flexible wall. The lateral support element is disposed along the associated flexible wall such that an interface (334) is formed between an outer surface of the associated flexible wall and the second surface of the lateral support element. The interface is operative to generate a lateral spring-rate profile in an associated gas spring assembly that varies according to lateral displacement of the associated flexible wall and the lateral support element relative to one another. The interface can include a quantity of friction-reducing material and/or can be at least partially formed by a cross-sectional profile of the lateral support element that includes a convex profile segment. Gas spring assemblies and methods of assembly are also included.

COMPACT DRIVE UNIT FOR TRACTION VEHICLES
A compact drive unit is predominantly intended for traction vehicles, especially for rail vehicles. This invention allows significant reduction of volume and weight of drive units. The drive unit comprises high-speed electrical motor (1) with passive cooling, which is supplied by power electronics converter (2), whose rotor is supported by bearings (3) along with pinion gear (4) of the input spur/helical gear (5). The output shaft (6) of the gear (5) is a part of the next following gear (7). Output shaft of this gear (7) can be connected either directly or by using the coupling (12) to the axle (8) of the traction vehicle, or to the wheel (9). Alternatively, in case the higher transmission ratio is required, it can be connected to another gears (10), where the output shaft of the gears (10) is connected to the wheel (9), or to the axle (8) of the traction vehicle directly or by using the coupling (12). The drive unit can be equipped with brake (13).
