Abstract
Angular and axial offsets between the motor vehicle rotor (3) and transmission pinion (6) are intended to be compensated by a coupling which can be mounted in an easy manner. According to the invention, a curved teeth coupling (9) is mounted between the motor shaft (4) and the pinion shaft (6) and includes a first coupling section (10) with internal tooth system and a second coupling section (11) with external tooth system, whereby the first coupling section (10) is securely connected to the pinion shaft (6) and the second coupling section (11) is securely connected to the motor shaft (4). The coupling sections (10, 11) can easily be pushed into each other, when the motor (2) is mounted onto the transmission (1).
