Problems solved by technology

The existing multi-gear transmission adopts a single intermediate shaft, and the output shaft driven gear of the main box and the driving gear of the intermediate shaft are arranged in series one by one. This method leads to the long length of the output shaft and the intermediate shaft of the main box, which makes the stiffness of the shaft poor. It is easy to cause the transmission to not work effectively
Moreover, the existing multi-gear transmission cannot realize non-power interrupted gear shifting, resulting in the process of gear shifting not being able to proceed smoothly, which affects the gear shifting performance of the vehicle

Abstract

The invention relates to the technical field of transmissions, in particular to a double-clutch transmission and a commercial vehicle, the double-clutch transmission comprises a clutch assembly, the clutch assembly comprises a C odd clutch and a C even clutch which are coaxially arranged, and both the C odd clutch and the C even clutch can be connected with or disconnected from a power input shaft; the first gear box comprises a main box body, and an odd-number gear shaft, an even-number gear shaft, a first intermediate shaft, a second intermediate shaft and a first-stage power output shaft which are rotationally arranged in the main box body; the second gearbox comprises an auxiliary box body, a power input assembly, a power output assembly and a secondary power output shaft, wherein the power input assembly, the power output assembly and the secondary power output shaft are rotationally arranged in the auxiliary box body. Non-power-interruption gear shifting can be achieved, and therefore the driving control performance of the vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of speed reducers, in particular to a dual-clutch transmission and a commercial vehicle. Background technique [0002] In a car, the transmission is an important power component, and the performance of the transmission determines the performance of the car. In existing commercial vehicles, in order to improve the control of speed and torque, a multi-gear output mode is adopted to meet the needs of driving. The existing multi-gear transmission adopts a single intermediate shaft, and the output shaft driven gear of the main box and the driving gear of the intermediate shaft are arranged in series one by one. This method leads to a long length of the output shaft and the intermediate shaft of the main box, which makes the stiffness of the shaft poor. It is easy to cause the transmission to not work effectively. Moreover, the existing multi-gear transmission cannot realize non-power interrupted gear shifting, ...
