Guide frame and brush assembly for, e.g. heat-engine starter of motor vehicle, has blocking structure which prevents movement of brush which goes out of guide frame

摘要

#CMT# #/CMT# The assembly (3) has guide frame (4) with a pressing structure (6) which ensures sufficient contact-pressure with respect to the commutator (1) of brush (5). The base (260) of guide frame opens and forms the groove. The brush is protruded outside from the groove of guide frame. The movement of brush which goes out of guide frame is prevented by the blocking structure. #CMT# : #/CMT# An independent claim is included for electric apparatus. #CMT#USE : #/CMT# Guide frame and brush assembly for brush holder of electric apparatus (claimed) such as rotating electrical machine e.g. heat-engine starter of motor vehicle. #CMT#ADVANTAGE : #/CMT# The contact area of the brush and the commutator is increased without expanding the dimension of the axial direction of segment of commutator. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cut-away perspective view of the guide frame and brush assembly of rising type commutator of electric apparatus. 1 : Commutator 3 : Guide frame and brush assembly 4 : Guide frame 5 : Brush 6 : Pressing structure 260 : Base.
