Abstract
The present invention relates to an improved structure of an automobile center lock driving apparatus, and in particular to an center lock driving apparatus having an inertia gear module. The driving apparatus comprises a driving pull-rod, a transmission gear, an inertia clutching gear, an active gear and a motor. The apparatus provides a solution to wear of the gears, dislocation of the gears, and “dead lock” of the driving pull-rod, and gear damages as a result of shock caused by dislocation of transmission gear modules. At instantaneous driving, the driving pull-rod can be driven more smoothly and stable as a result of the inertia gap between the gear modules.
