Abstract

The disclosure relates to a drive train (100) for a vehicle, comprising: a split drive axle (102) having a first drive shaft (104) and a second drive shaft (106), an input gear (108) being couplable to a drive unit of the vehicle for providing an input torque (T<in>) to a differential gear unit (110), the differential gear unit (110) being configured to distribute the input torque (T<in>) on the first drive shaft (104) and the second drive shaft (106), the differential gear unit (110) comprising: a distribution gear box (116) being coupled to the input gear (108) in a torque-transmitting manner and configured to distribute a first portion (T<1>) of the input torque (T<in>) evenly between the first drive shaft (104) and the second drive shaft (106), an internal gear (118) being coupled to the input gear (108) in a torque-transmitting manner for providing a second portion (T<2>) of the input torque (T<in>), and an external gear (120) being coupled to the input gear (108) in a torque-transmitting manner for providing a third portion (T<3>) of the input torque (T<in>), a first transmission gear assembly (124) and a first clutch (126), the first transmission gear assembly (124) being configured to connect the internal gear (118) of the differential gear unit (110) and the first clutch (126) in a torque-transmitting manner, and the first clutch (126) being configured to transmit the second portion (T<2>) of the input torque (T<in>) to the second drive shaft (106), when being in an at least partly closed state, a second transmission gear assembly (128) and a second clutch (130), the second transmission gear assembly (128) being configured to connect the external gear (120) of the differential gear unit (110) and the second clutch (130) in a torque-transmitting manner, and the second clutch (130) being configured to transmit the third portion (T<3>) of the input torque (T<in>) to the second drive shaft (106), when being in an at least partly closed state, wherein the input torque (T<in>) corresponds to a sum of the first portion (T<1>) of the input torque (T<in>) and the second portion (T<2>) of the input torque (T<in>) or a sum of the first portion (T<1>) of the input torque (T<in>) and the third portion (T<3>) of the input torque (T<in>).
