Electric servo steering device for vehicles, has eccentric device, which approaches rotating shaft by rotating crankcase relative to gearbox in kind of parallel displacement at rotating axis of worm wheel or moves away from rotating shaft

摘要

The electric servo steering device (100) has an engine (60) and a worm gear (62), which is so provided at the rotating shaft (61) of the engine. A worm wheel (13) meshes with the worm gear and produces a connection to a steering system (5,8,9). A crankcase of the engine is arranged at the gearbox (20). An eccentric device approaches the rotating shaft by rotating the crankcase relative to the gearbox in the kind of a parallel displacement at a rotating axis of the worm wheel or moves away from the rotating shaft.
