Slide sleeve for gear-box synchronizer unit has gear-shift fork guide, inner cogging, conical friction surfaces, friction rings and main body

摘要

The slide sleeve (1) has a gear-shift fork guide(5) formed by sections of an outer surface of the slide sleeve. Inner cogging (2a) on a section of an inner casing surface of the slide sleeve runs towards the lengthwise center axis of the slide sleeve. Conical friction surfaces (14) on at least one casing surface of the slide sleeve run towards the lengthwise center axis of the slide sleeve which consists of a main body (2), and first (3) and second (4) friction ring. The facing end surfaces (3a,4a) of the two friction rings are fixed parallel to one another on the main sleeve body.
