Automobile transmission synchronizer

Abstract

The invention discloses an automobile transmission synchronizer. The automobile transmission synchronizer comprises a gear hub. Modified gears are arranged on two sides of the gear hub respectively. Asliding sleeve is arranged outside the gear hub in a sliding and sleeving mode. The two ends of each outer spline of the sliding sleeve are each provided with a sliding sleeve locking surface. The outer surface of the sliding sleeve is fixedly provided with a sliding disc in a sleeved mode. An even number of sliding disc notches are formed in the inner surface of the sliding disc. The positions,corresponding to the two sides of the sliding disc, of the outer surface of the sliding sleeve are each sleeved with a synchronization ring in a sliding mode. The inner end surface of each synchronization ring is provided with limiting bosses inserted in the sliding disc notches at intervals. The inner surface of each synchronization ring is provided with inner splines, the inner splines and the sliding disc notches are arranged in a staggered mode, the inner end of each inner spline of each synchronization ring is provided with a synchronization ring locking surface, and the outer surface ofeach synchronization ring is a frication cone surface. The outer surface of the sliding sleeve is provided with elastic pieces capable of driving the synchronization rings to slide. Each modified gearis fixedly provided with a friction cone disc. The inner surfaces of the friction cone discs are friction cone surfaces matched with the frication cone surfaces of the synchronization rings. The automobile transmission synchronizer is suitable for a transmission.

Description

technical field [0001] The invention relates to the field of synchronizers, in particular to an automobile gearbox synchronizer. Background technique [0002] The synchronizer is an important part of the automobile transmission. It makes the input and output parts of the synchronizer synchronized and then combined, thereby reducing the impact and noise when shifting gears, reducing the shifting force, making the shifting smooth and light, and reducing the driver's fatigue. It plays an extremely important role in reducing fatigue, prolonging the life of the transmission, improving the driving safety and ride comfort of the car, and improving the acceleration and economy of the car when it starts. As a key component of the transmission, the synchronizer's performance directly affects the performance of the shifting mechanism. When the transmission is in gear, if the synchronization performance is insufficient, it will produce a gear shifting shock, which will affect the smooth...

Problems solved by technology

[0007] Compared with traditional synchronizers, this high-torque synchronizer has a larger friction circle diameter, that is, a larger synchronizer capacity, and removes the slider groove, which enhances the strength of the gear hub, but due to the The internal friction cone is designed on the gear sleeve, and the axial size of the gear sleeve is limited, so the width of the friction cone is small
