Electric switchgear for vehicle gear change box, with gearshift element

摘要

An electric motor (1) produces a rotary (R) and a linear (L) movement of the gearshift element. The electric mtoor has a threaded spindle (5) on which is an axially guided nut (6) which is secured by a linear guide (8) against rotation. A sliding sleeve (10) is axially and rotarily movable to a limited extent on the threaded spindle and contains a longitudinal slot (9) forming the nut's linear guide. The sliding sleeve is joined to the threaded spindle or to a fixed component by a coupling (12,13,19,20). The coupling consists of coupling surfaces (13,20) at each end of the sliding sleeve. One surface can be connected to a radial coupling surface (12) on a transmission gear (2). The other coupling surface is connected to a radial coupling surface (19) on a coupling flange (15) joined to the treaded spindle. Electric coils (11,18) are positioned directly next to the coupling surfaces (12,19).
