Actuating drive for controlling motor vehicle transfer gear-box, has plastic housing part, which is made up of injection molding processible material, closed at housing, and light metal cover closed at housing part

摘要

#CMT# #/CMT# The drive (1) has a plastic housing part (6) made up of an injection molding processible material and closed at a housing (4). The housing part is provided with axially-parallel ribs. The housing part is mechanically connected with a brush beam (23) and an eccentrically arranged connector. A light metal cover (9) that is closed at the housing part is provided below an intermediate layer of a sealing. The cover includes a passage for a motor shaft and a connection area for attachment with a transfer gear-box housing. A rotor is stored in a bearing that is received in a stator part of a brake. #CMT#USE : #/CMT# Actuating drive for controlling a motor vehicle transfer gear-box. #CMT#ADVANTAGE : #/CMT# The plastic housing part of actuator comprises a high stiffness, strength, heat resistance, corrosion resistance, low creep strength, high dimensional stability and less warpage, so that the actuator is economically producible. The housing part is made up of plastic, thus reducing the weight of actuator about 50 percent to 70 percent lower than that of the light metal cover. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a three-dimensional view of an actuating drive for controlling a motor vehicle transfer gear-box. 1 : Actuating drive 4 : Housing 6 : Plastic housing part 9 : Light metal cover 23 : Brush beam.
