Abstract
The invention discloses an asymmetric locking surface automobile synchronizer which comprises a synchronous slide sleeve (1), two synchronous cone hubs (2), two synchronous toothed rings (3) and a synchronous tooth holder (4). The outer circle of the synchronous tooth holder (4) is sleeved with the synchronous slide sleeve (1). A supporting assembly is arranged between one part of the synchronous tooth holder (4) and the synchronous slide sleeve (1). The other part of the synchronous tooth holder (4) is in transmission connection with the synchronous slide sleeve (1) through a spline. The synchronous slide sleeve (1) rotates together with the synchronous tooth holder (4). The synchronous slide sleeve (1) axially moves leftwards and rightwards on the synchronous tooth holder (4) during gear shifting. The two synchronous toothed rings (3) are pressed on the two surfaces of the synchronous tooth holder (4). The two synchronous cone hubs (2) are correspondingly arranged on the outer sides of the two synchronous toothed rings (3). External conical surfaces are arranged on the two synchronous cone hubs (2). Internal conical surfaces are arranged on the two synchronous toothed rings (3). Friction torque is produced after the internal conical surfaces of the synchronous toothed rings (3) and the external conical surfaces of the synchronous cone hubs (2) are correspondingly combined.
