Abstract

The invention relates to a gear combined type variable-speed transmission device. The gear combined type variable-speed transmission device consists of an input shaft, an output shaft, an intermediate shaft, clutches (or synchronizers) and gears. More than 6 clutches or one clutch and more than 6 synchronizers and more than 9 gears are combined in serial-parallel connection modes, the gear number is remarkably increased, and the number of shifting gears is decreased. Due to the fact that each pair of gears has small speed ratio and adopts a short transmission shaft structure, the rigidity of a transmission is improved, the radial and axial sizes are reduced, and the transmission is compact in structure and high in mechanical efficiency. The invention further provides a reverse gear device used on a mechanical variable-speed transmission mechanism.

Description

technical field [0001] The invention relates to a mechanical speed change transmission device, in particular to a combined speed change transmission device of a clutch, a synchronizer and a gear. Background technique [0002] Currently, there are three main types of automatic transmissions used in automobiles: hydraulic automatic transmission (AT), electromechanical automatic transmission (AMT) and mechanical continuously variable automatic transmission (CVT). In the field of electronically controlled mechanical automatic transmission, there is also a variable speed transmission method, that is, dual-clutch automatic transmission (DSG). The mechanical automatic transmission (AMT) is based on the manual transmission, and an automatic control device is added to control the clutch and select the gear pair on the fixed shaft system for automatic gear shifting. The electro-hydraulic automatic transmission (AT) has a series of planetary gear trains and multiple clutches and brake...
