Abstract

The invention discloses a multi-gear vertical dual clutch transmission, which comprises a nesting shaft, an intermediate shaft, an output shaft and a reverse gear shaft, wherein the intermediate shaft, the output shaft and the reverse gear shaft are parallel with each other; the nesting shaft and the output shaft are collinear; the solid input shaft of the nesting shaft is provided with a dual clutch; all gears of gear pairs are respectively arranged on a hollow input shaft and the intermediate shaft, or the solid input shaft and the intermediate shaft; the intermediate shaft and the output shaft are provided with a high-speed gear pair, a low-speed gear pair, a first synchronizer and a second synchronizer; the output shaft is provided with a fourth synchronizer; and a third synchronizer is arranged on the intermediate shaft and is located between a high-speed driving gear and a low-speed driving gear, or is arranged on the output shaft and is located between a high-speed driven gear and a low-speed driven gear. In the multi-gear vertical dual clutch transmission, the implementation of all gears needs to be completed by the joint participation of 1-2 synchronizers; on the premise of not increasing the number of meshing gear pairs, through the joint utilization of all the gears of the gears and the alternating action of the four synchronizers, multi-gear drive and a wider drive ratio range are realized, and the number of the gears and the synchronizers is reduced, so that the layout of the vertical transmission is more compact, the manufacturing cost is saved, and the lightweight requirement of a whole vehicle is met. The multi-gear vertical dual clutch transmission of the vehicle can realize eight forward gears and two reverse gears at most.

Description

technical field [0001] The invention belongs to the field of automobiles, and relates to a vehicle speed change device, in particular to a multi-gear longitudinal dual-clutch transmission. Background technique [0002] Due to the different arrangement of the engine, the transmission can be divided into horizontal and longitudinal. From the perspective of the overall vehicle layout, the vertical arrangement is generally suitable for front-rear-drive models, and the transverse arrangement is suitable for front-front-drive models. In the shaft gear transmission layout inside the transmission, there are single countershaft and multiple countershaft structures, and the number of countershafts determines the length of the transmission. The dual-clutch transmission overcomes the problem of power interruption and improves the power and fuel economy of the vehicle. The TCU controls the switching timing of each gear and the engagement degree of the clutch according to the vehicle ru...
