Actuating drive device for motor vehicle - has drive pinion and output gear with toothing profile over lap of more than 1.0

摘要

The device consists of a drive pinion (3) and a meshing output gear (5). Pinion and gear have a toothing profile overlap of more than 1.0. In present end position, the two are precisely aligned, so that at least two teeth (13a,b,15a,b) of pinion and gear mesh simultaneously. The first end tooth of the gear, which engages first with the pinion, has a mechanically enforced gear tooth base on the tooth profile (23) facing the contact. The output gear consists of a sector gear part.
