A lock pin-type automobile synchronizer includes a higher gear conical ring (1) and a lower gear conical ring (4) which are arranged at the sides of a sliding gear sleeve (3). A higher gear lock pin (2) is fixed to one side of the higher gear conical ring (1). A lower gear lock pin (5, 6) is fixed to one side of the lower gear conical ring (4). A pin hole corresponding to the higher gear (2) lock pin and the lower gear lock pin (5, 6) is arranged on the sliding gear sleeve (3). The number of lower gear lock pins (5, 6) is higher than the number of higher gear lock pins (2).

This invention relates to a main-box-and-auxiliary-box-structural twin-countershaft twelve-speed transmission, with a main box and an auxiliary box mainly. Said main box has an input shaft (1), a main shaft (10) and two countershafts (14) arranged symmetrically at the two sides of the main shaft, there being provided corresponding gear drive between the main shaft and the countershafts, there being provided six gears positioned independently and three synchronizers (4) on the main shaft, shift forks (5) for the synchronizers are connected to a shift lever via shift fork shafts (16) and via an operation mechanism. The auxiliary box has an auxiliary-box main shaft (20) and an auxiliary-box countershaft (22), a gear (29) engaging with a gear (28), a gear (25) engaging with a shaft gear (30), between the gear (25) and the gear (29) being arranged a synchronizer (9), a shift fork (15) and a shift fork shaft (31), said synchronizer (9) being self-locked by means of back taper teeth, and said shift fork shaft (31) being self-locked by means of a self locking mechanism comprising a spring (18) and a steel ball (19).
