Abstract
A reverse brake mechanism for an automobile transmission has a synchronizing mechanism including a clutch sleeve, mounted for sliding movement on a primary transmission shaft, which has peripheral clutch teeth with chamfers arranged at regular separations. A synchronizing ring, mounted for rotation on the primary shaft, has peripheral synchronizing teeth with chamfers arranged at regular separations, and a brake member is provided for braking the primary shaft. The brake member is operationally coupled to the primary shaft through the synchronizing ring while the clutch sleeve is brought into engagement with the synchronizing ring through their teeth with chamfers when shifting the automobile transmission to a reverse gear.
