5 / reverse speed synchronizer key danyong off preventing structure of a manual transmission vehicle

摘要

The subject innovation discloses a five-speed / reverse speed danyong synchronizer key withdrawal prevention structure for a vehicle manual transmission. The subject innovation is described, the 5-stage gear is splined on the shaft coupling (1), clutch hub (2); A clutch sleeve that is coupled to the outer spline of the clutch hub 2, by sliding the operating force of the shift lever; The synchronizer key (6) interposed between said clutch sleeve and the hub (2); And the 5-speed / reverse speed danyong synchronizer key for a vehicle manual transmission that includes a retainer ring 20 fitted on the other side of the axis (1) of the 5th gear to limit the stroke during the reverse speed of the synchronizer key 6 in the withdrawal prevention structure, the retainer ring 20 is in close contact with one side of the clutch hub (2), the outer diameter has a shorter length than longer than the inner diameter of the synchronizer key (6) outer diameter, a synchronizer key 6 a head characterized in that the outer periphery has a groove 21 that the synchronizer key 6 during the reverse shift enters in the axial direction formed by a predetermined length.
