Abstract

The invention provides a variable-speed transmission mechanism of a double-clutch speed changer. The variable-speed transmission mechanism of the double-clutch speed changer is used for solving the problem of vehicle power transmission and comprises a first input shaft, a second input shaft, a first intermediate shaft, a second intermediate shaft and a differential mechanism output assembly. The first input shaft and the second input shaft with a hollow structure are installed in sleeved mode, the first input shaft is an odd-gear and reverse-gear driving gear fixing shaft, the second input shaft is an even-gear driving gear fixing shaft, driven gears at different gears and synchronizers are sleeved on the first intermediate shaft and the second intermediate shaft, and the first intermediate shaft and the second intermediate shaft are respectively connected with the differential mechanism output assembly. The variable-speed transmission mechanism of the double-clutch speed changer is characterized in that a third-gear driven gear and a reverse-gear idle gear are sleeved on the second intermediate shaft and are of a connection tooth structure. The variable-speed transmission mechanism of the double-clutch speed changer is compact in arrangement, smooth in power connection and rapid in gear shifting response and remarkably improves power performance and economic performance of a vehicle.

Description

technical field [0001] The invention relates to a dual-clutch transmission, in particular to a speed-changing transmission mechanism of the dual-clutch transmission, which belongs to the technical field of vehicle transmissions. Background technique [0002] The transmission is one of the main components in the car transmission system. It can not only change the speed of the car and the torque on the driving wheels of the car in a wide range, but also realize the reverse running and the neutral operation of the engine. According to the different operating methods, the transmission It can be roughly divided into three categories: manual transmission, automatic transmission and dual-clutch transmission (DCT). According to the layout of the engine, automobile transmissions can be divided into horizontal and vertical. For front-wheel-drive models. [0003] The horizontal dual-clutch transmission contains two automatically controlled clutches, and its transmission mechanism adop...
