Embodiment Construction

[0023] figure 1 A drive train 1 is shown, which is used, for example, in a motor vehicle. Here, a main prime mover 2 in the form of an internal combustion engine is connected to a main transmission 3 with a transmission output shaft 4 , which leads to a first axle differential 5 arranged on a drive shaft 6 of the motor vehicle. Based on this configuration, the main prime mover 2 drives the wheels 10 , 11 connected to said first drive shaft 6 .

[0024] The electric motor 7 designed as an outer rotor mounted as an auxiliary prime mover is connected to an auxiliary transmission 8 , which in turn is designed as a single-stage or multi-stage planetary transmission. The last transmission stage 8 a of the auxiliary transmission 8 is connected here to a coupling element 9 in the form of a clutch, which connects the electric motor 7 to the transmission output shaft 4 or disconnects this connection. The electric motor 7 and the auxiliary transmission 8 are arranged as a compact unit ...

Abstract

The invention relates to a drive train for a motor vehicle, which comprises a main motor and an auxiliary motor. The main motor is used for driving the wheel of the motor vehicle with a drive shaft through a main transmission. The main transmission is connected with a first differential mounted on the drive shaft through the output shaft of the transmission. The auxiliary motor is connected with the output shaft of the transmission through an auxiliary transmission and is used for driving the motor vehicle at a low speed. In order to reduce the occupation space of the structure of the auxiliary motor in service, preferably, the auxiliary motor and an electric motor are arranged coaxially relative to the output shaft of the transmission.

Description

technical field [0001] The invention relates to a drive train for a motor vehicle, comprising a main prime mover and an auxiliary prime mover, the main prime mover driving the wheels of the drive shaft of the motor vehicle through a main transmission, the main transmission being supported on the drive shaft through a transmission output shaft The auxiliary prime mover is connected to the transmission output shaft through the auxiliary transmission for driving the motor vehicle at low speeds. Background technique [0002] Document WO 00 / 20243 A1 discloses motor vehicles in which the electric motor is connected within the drive train of the motor vehicle via a transmission. It is also known that the electric motor is arranged axially parallel to the transmission output shaft and is connected to the transmission output shaft via an auxiliary transmission and a coupling element, preferably a freewheel. Alternatively, the coupling element can also be designed as a clutch. The c...
