Abstract

The invention relates to a transmission system with a one-way self-adaptive joint device and a gear shifting control method thereof.The transmission system comprises a gear shifting executing mechanism, a driving motor, a mechanical transmission and the one-way self-adaptive joint device, and the mechanical transmission comprises a power input unit with a change gear and a power output unit; the one-way self-adaptive joint device comprises a first joint gear ring, a second joint gear ring and a joint sleeve, the joint gear ring is in transmission connection with a speed change gear corresponding to the power output unit, and the joint sleeve is fixedly connected with the power output shaft and is pushed by the gear shifting execution mechanism to be jointed with the first joint gear ring or the second joint gear ring. The gear shifting control method comprises the steps of unloading, gear disengagement, gear engagement and torque recovery of the driving motor. The driving motor can control the joint gear ring to be matched with the rotating speed of the target gear, and then the gear shifting executing mechanism pushes the joint sleeve to be in butt joint with the joint gear ring at the rotating speed of the target gear, so that rapid gear shifting is achieved, and impact force of gear shifting is effectively buffered.

Description

technical field [0001] The invention relates to the technical field of vehicle shifting, in particular to a transmission system with a one-way adaptive engagement device and a shifting control method thereof. Background technique [0002] The electrification of vehicles is an important measure for energy conservation and emission reduction in my country. Installing a transmission in an electric vehicle can expand the torque range of the drive motor, make the drive motor work in the high-efficiency area, and greatly improve the power and economy of the vehicle. The motor direct-connected mechanical transmission system has a simple structure and low cost, and is an ideal electric drive configuration. However, the large shift shock and long power interruption time during the shift process are important factors affecting its wide application. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a transmission system with a one-way adaptive enga...
