Drivetrain unit for a hybrid vehicle having axial compensation

Abstract

The invention relates to a drivetrain unit (1) for a motor vehicle, comprising a housing (2), an input shaft (3) rotatably mounted in the housing (2), which is prepared for rotationally fixed attaching to an output (4) of a transmission (5), and comprising an electric machine (6) which is arranged axially parallel to the input shaft (3), and a first coupling (7) which connects a rotor (8) of the electric machine (6) and the input shaft (3) for torque transmission in a shift position, and comprising an output shaft (8) rotatably mounted in the housing (2), which is prepared for rotational coupling to a distributer transmission, and a second coupling (9) which connects the input shaft (3) and the output shaft (8) for torque transmission in a shift position, wherein the input shaft (3) has afirst input shaft section (20) and a second input shaft section (21) that can move axially in relation to the first input shaft section (20).

Description

technical field [0001] The invention relates to a drive train unit for a motor vehicle, in particular a hybrid driveable motor vehicle, such as a car, truck, bus or other utility vehicle. Background technique [0002] Automatic transmissions for motor vehicles are generally known from the prior art. So-called P3 electric machines are also known, which are arranged on the transmission output of the automatic transmission and can be coupled and decoupled by means of a separating clutch. A further clutch ensures that the output of the transmission is coupled, in addition to the wheels of the front axle, optionally also to the wheels of the rear axle for all-wheel drive. [0003] However, the prior art always suffers from the following disadvantages: Due to the bearings of the (automatic) transmission, due to the helical-toothed spur gear depending on the helix angle, helix direction (and thus on the gear, temperature and torque), in the backlash state, in the Larger axial dis...
