Abstract

The invention provides a double-clutch transmission hydraulic gear shifting system which comprises an oil supply device, a first oil way, a second oil way and a controller. The first oil way and the second oil way are connected to the oil outlet end of the oil supply device in parallel. Each of the first oil way and the second oil way comprises an energy accumulator and a hydraulic cylinder which are connected with the oil outlet end of the oil supply device, and further comprises a first detector connected with the energy accumulator, the first detector is in communication connection with the controller, and the oil outlet end of the hydraulic cylinder is connected with the oil inlet end of the oil supply device. According to the hydraulic gear shifting system of the double-clutch transmission, energy consumption generated in the gear maintaining and gear shifting process of an oil supply device of the double-clutch transmission is reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile hydraulic control, and more particularly relates to a hydraulic shifting system of a double clutch transmission. Background technique [0002] Automobile transmission usually includes manual transmission and automatic transmission. Manual transmission has the characteristics of fast response and low fuel consumption, but requires manual operation and requires high driving skills; automatic transmission does not require manual operation, which is convenient and fast, but has poor power. [0003] The dual-clutch transmission has two clutches, one for odd gears and one for even gears. When one gear is used, the other gear is ready for gear shifting, which can complete gear shifting in a very short time, making power transmission possible. uninterrupted. The dual clutch transmission is very similar in nature to the manual transmission. The existing dual clutch transmission requires the oil supply ...
