A torque vectoring device (30) for a drive axle (12) of a vehicle (10). The torque vectoring device (30) comprises an electric torque vectoring motor (32), a planetary gear (34) and a countershaft (36) configured to couple with a cage (26) of a differential gear (24), the planetary gear (34) comprising a differential gear (24) configured to couple with a left or right wheel drive shaft (16; 18) and a second output coupled to the countershaft (36). The torque vectoring motor (32) forms a first torque flow path (38) with the planetary gear (34) and the countershaft (36) and forms a second torque flow path (40) with the first output of the planetary gear (34), where the first torque flow path (38) and the second torque flow path (40) are arranged kinematically parallel. The countershaft (36) is arranged eccentrically with respect to the first output of the planetary gear (34).
一种扭矩矢量装置(30),用于一车辆(10)的一驱动桥(12)。所述扭矩矢量装置(30)包括一电动扭矩矢量电机(32)、一行星齿轮(34)及配置成与一差速齿轮(24)的一保持架(26)耦合的一副轴(36),所述行星齿轮(34)包括配置成与一左或右轮传动轴(16;18)之一耦合的一第一输出端以及与所述副轴(36)耦合的一第二输出端。所述扭矩矢量电机(32)与所述行星齿轮(34)及所述副轴(36)形成一第一扭矩流动路径(38),并与所述行星齿轮(34)的所述第一输出端形成一第二扭矩流动路径(40),其中所述第一扭矩流动路径(38)及所述第二扭矩流动路径(40)在运动学上平行布置。所述副轴(36)与所述行星齿轮(34)的所述第一输出端偏心布置。
