Problems solved by technology

[0003] At present, the forward transmission mechanism of the automobile transmission device is composed of gears and synchronizers. When the forward transmission is switched, the synchronizer is used to slow down the impact of shifting; the reverse transmission is composed of three gears. When the reverse transmission is switched, the two gears do not The other gear is in sliding contact. During the contact process, there will be obvious collision and impact due to the large speed difference, which seriously affects the stability of the transmission system and the safety of the vehicle.
