The invention has the advantages of simple structure, low manufacture difficulty, high working efficiency, and reliable operation.

Description

technical field [0001] The invention belongs to the field of automobile manufacturing, and in particular relates to a mechanical transmission. Background technique [0002] At present, most of the transmissions in the field of automobile manufacturing are mechanical manual gear shifting. The gear shifting action is realized by manually controlling the joystick, and the clutch clutch action is realized through the foot pedal. During the gear shifting and clutching action process , the driver needs to skillfully control the joystick and clutch pedal. The main disadvantage is frequent manipulation and high labor intensity. Most of the automatic shift transmissions used in some high-end passenger cars are hydraulic transmission automatic shift transmissions (AT), whose main disadvantages are low efficiency, high energy consumption, poor maintainability and assembly. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome ...
