A positioning unit for technical applications in motor vehicles, in particular a locking system, a door positioner or a sliding door drive, having a housing, a drive arranged in the housing, a control element which can be acted upon by the drive, and a bearing location for the drive, in which the bearing location is formed at least partly of plastic, wherein the bearing is designed as a separate bearing location, and at least part of the drive is insertable into the bearing location.

A profiled wheel assembly for coupling to a shaft includes a profiled wheel having a first guide slot extending radially outwardly from a central aperture of the profiled wheel and a first assembly slot spaced apart from and parallel to the first guide slot. A retainer is supported on the profiled wheel for movement between a lock position wherein the retainer axially locks the profiled wheel relative to the shaft and a release position wherein the retainer axially unlocks the profiled wheel relative to the shaft.

Bearings (72, 74) are arranged for a drive unit (10) having an electric motor for providing drive to an electric axle and a wheel assembly of a vehicle. The drive unit includes a pair of bearings and a reduction gear assembly (12) with a first drive gear mounted to and coaxial with the main shaft of the motor, and a first driven gear rotatably coupled to the first drive gear and mounted to and coaxial with an intermediate shaft to form an intermediate shaft assembly. The reduction gear assembly includes a second drive gear mounted to and coaxial with the intermediate shaft, and a second driven gear rotatably coupled with the second drive gear. A first bearing of said pair of bearings is mounted to a bulkhead and to said intermediate shaft assembly between the first driven gear and second drive gear to reduce the distance between the first and second bearings.
