    • 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).
    • 紧凑型驱动单元主要用于牵引车辆,尤其是轨道车辆。 本发明允许显着减小驱动单元的体积和重量。 驱动单元包括由功率电子转换器(2)提供的具有被动冷却的高速电动机(1),其转子由输入正弦/斜齿轮的小齿轮(4)与轴承(3) (5)。 齿轮(5)的输出轴(6)是下一个齿轮(7)的一部分。 该齿轮(7)的输出轴可以直接或通过联轴器(12)连接到牵引车辆的轴(8)或车轮(9)上。 或者,在需要较高传动比的情况下,其可以连接到齿轮(10)的输出轴连接到轮(9)的另一个齿轮(10),或连接到齿轮(10)的轴(8) 牵引车直接或通过使用联轴器(12)。 驱动单元可以配备制动器(13)。
