The invention relates to a drive train (1) for an electric vehicle, comprising a drive unit (2), a differential (3), a transmission stage (4), two drive wheels (5) which are each connected to the differential (3) by means of an axle, at least one first brake system (11), the first brake system is located on one of the axles and is composed of a wet-running service brake (8), a parking brake (9) and an actuator (10) for actuating the wet-running service brake (8) and the parking brake (9) in a controllable manner. In order to improve the driving and braking characteristics and to avoid shift effects and torsion play, the transmission stage (4) is arranged between the drive unit (2) and the differential (3), and the drive wheels (5) are operatively connected directly to the differential (3).

    本发明涉及一种用于电动车辆的动力总成(1),所述动力总成具有驱动单元(2)、差速器(3)、变速级(4)、两个分别通过一轮轴与所述差速器(3)连接的驱动轮(5)、至少一个第一制动系统(11),所述第一制动系统位于所述轮轴其中之一处并且由湿式运行的行车制动器(8)、驻车制动器(9)以及致动器(10)构成,所述致动器用于以可控制的方式操纵所述湿式运行的行车制动器(8)以及所述驻车制动器(9)。为了改进行驶特性和制动特性以及避免变速影响和扭转间隙,所述变速级(4)布置在所述驱动单元(2)和所述差速器(3)之间,并且所述驱动轮(5)直接与所述差速器(3)有效连接。
