Abstract

The invention discloses a speed change mechanism of a vehicle and the vehicle with the speed change mechanism. The speed change mechanism of the vehicle comprises a first input shaft, a second input shaft, a first output shaft, a transmission shaft and a second output shaft, wherein the first input shaft is connected with an engine through a first clutch; the second input shaft is connected with the engine through a second clutch; the first input shaft and the second input shaft are provided with multiple driving gears; the first output shaft is sleeved with the transmission shaft; the first output shaft, the transmission shaft and the second output shaft are provided with multiple synchronizers and multiple driven gears meshed with the driving gears; and a first gear of the speed change mechanism achieves power transmission through the driving gears and the driven gears of other same gears. The speed change mechanism provided by the invention has the advantages of being low in cost, small in size and the like.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to a speed change mechanism of a vehicle and a vehicle having the same. Background technique [0002] The transmission mechanism of the vehicle in the related art is usually equipped with two clutches to improve the smoothness of shifting, and the gear train can be arranged in parallel to reduce the size of the transmission mechanism. It can significantly improve the power, economy and grade of the whole vehicle. However, the setting of the shifting structure still has the problems of high cost and large radial size. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide a transmission mechanism for a vehicle, which has the advantages of low cost and small size. [0004] In order to achieve the above object, according to the firs...
