Abstract

The invention provides a transmission system. T he transmission system comprises a main shaft and an auxiliary shaft; the main shaft and the auxiliary shaft are sleeved with a first gear and a secondgear in a non-contact manner; wherein the main shaft is connected with a first joint mechanism, the first joint mechanism is used for enabling the first gear and the main shaft to be synchronous or disconnected, the auxiliary shaft is connected with a second joint mechanism, the second joint mechanism is used for enabling the second gear and the auxiliary shaft to be synchronous or disconnected, and the first gear is connected with the second gear. According to the invention, the first gear is connected with the second gear. Therefore, the first joint mechanism and the second joint mechanism can jointly act to control the transmission system. Compared with a traditional transmission system with one joint mechanism controlling one gear, the transmission of the transmission system provided by the invention can be controlled through simultaneous action of the two mechanisms, and the simple arrangement mode provides possibility for expanding the speed ratio and the gear number of the transmission system. The invention further provides a gear shifting method.

Description

technical field [0001] The invention relates to a transmission system and a shifting method thereof. Background technique [0002] The prior art discloses a four-speed gearbox for electric vehicles, including a motor, a gearbox and a hydraulic system for driving a shift clutch. The first shift clutch is arranged on the main shaft of the gearbox. The driving wheel is rigidly connected to the first shifting clutch, the second shifting clutch is set on the main shaft of the gearbox, the second-speed driving gear, and the fourth-speed driving wheel are rigidly connected to the second shifting clutch, and the clutch is controlled by an electromagnetic reversing valve to realize shifting. block operation. [0003] The driving gear of the main shaft and the driven gear of the auxiliary shaft in the above technology mesh one by one. It is difficult to arrange a large speed ratio gearbox suitable for commercial vehicles by using the above technology, and it cannot meet the needs of ...
