Abstract

The invention discloses an automobile synchronizer. Positions of locking pin holes (6) correspond to those of first locking pin holes (7) and those of second locking pin holes (8), and a sliding gearsleeve (1), a first synchronous conical ring (2) and a second synchronous conical ring (3) are connected into a whole by inserting locking pins (5) into the locking pin holes (6), the first locking pin holes (7) and the second locking pin holes (8); multiple locating ring slots (10) are formed in the groove bottom of a shifting fork groove (9) in the radial direction, and each locating ring slot (10) corresponds to one locking pin hole (6) of the sliding gear sleeve (1); a locating slot (11) is formed in the middle of each locking pin (5), and each locating slot (11) corresponds to one locating ring slot (10); and locating clamping slots (12) are formed in the groove bottom of the shifting fork groove (9), each locating snap spring (4) is embedded into the corresponding locating clamping slot (12), the outer side of each locating snap spring (4) is located in the corresponding locating slot (11), and a locking surface (14) of each locking pin (5) corresponds to one locking angle (13) of the corresponding locking pin hole (6).

Description

technical field [0001] The invention relates to an automobile synchronizer. Background technique [0002] Automobile synchronizer is a key component of mechanical gear transmission. The synchronizer is responsible for shifting gears and transmitting torque. It is a key and vulnerable part in the gearbox. At present, it is inconvenient to use the synchronizer to shift gears. When shifting gears, the gears and shafts are strongly impacted, which slows down the life of the transmission, is labor-intensive, and reduces the power and fuel economy of the car. Contents of the invention [0003] The invention provides an automobile synchronizer, which not only realizes positioning when the synchronizer is in neutral. The number of parts is reduced, the failure rate of the synchronizer is reduced; the difficulty of processing the synchronizer is reduced, and the production cost is reduced. [0004] The present invention adopts the following technical solutions: an automobile sync...
