Triebsatzschwinge für ein- oder mehrspurige, elektromotorisch angetriebene Fahrzeuge

摘要

The invention relates to a swinging arm motor unit (10) for single-track or multiple-track motor driven vehicles, in particular motor scooters. This swinging arm motor unit (10) has a driving motor (14), configured as an electric motor, mounted at one end of an elongated swinging housing (12), and a rotating hub (16) for fixing a vehicle drive wheel (18) at the other end of the swinging housing. The drive shaft of the driving motor (14), which is guided into the swinging housing (12), is rigidly coupled to the hub (16) for the vehicle drive wheel, by means of a transmission unit (26) enclosed in the swinging housing. There are also units for lodging the swinging housing (12) so that it can swing around an axle situated at a distance from and parallel to the rotational axis of the wheel hub (16), or in the frame or the chassis of the motor driven vehicle. There is at least one free wheel coupling (38a, 38b) in the transmission between the motor (14) and the wheel hub (16), which cancels out the rigid coupling of the driving shaft of the driving motor to the vehicle drive wheel (18), when the drive torque applied to the transmission unit (32) by the driving motor (14) is less than a rotating torque applied to the transmission unit by the drive wheel (18) via the wheel hub (16).
