Abstract

The invention discloses a transmission and a gear selecting and shifting mechanism. The gear selecting and shifting mechanism includes a plurality of gear racks, a gear shifting shaft, a gear selecting motor and a gear shifting motor, wherein pushing fingers are arranged on the back sides of all the gear racks, the gear shifting shaft is fixedly provided with a gear shifting gear, the gear shifting gear can mesh with any of the gear racks, the gear selecting motor is connected with the gear shifting shaft in a transmission mode and is capable of driving the gear shifting shaft to move in the axial direction of the gear shifting shaft so that the gear shifting gear can mesh with different gear racks, the gear shifting motor is connected with the gear shifting shaft in a transmission mode and is capable of driving the gear shifting shaft to rotate around the axial direction of the gear shifting shaft so as to drive the gear rack which meshes with the gear shifting gear to act, and then the pushing fingers of the gear racks push gear shifting pushing forks arranged in the transmission. The structure of the gear selecting and shifting mechanism is simpler and the gear selecting and shifting mechanism has a higher integration degree.

Description

Technical field [0001] The invention relates to the technical field of transmissions, in particular to a transmission and a gear selection and shift mechanism thereof. Background technique [0002] In current automatic transmissions, especially DCT (Dual Clutch Transmission) as an example, hydraulic actuators are commonly used in their shift mechanisms. When shifting, the hydraulic actuators can push the forks to achieve shifts. Each shift fork controls two gears, and the shift fork is mounted on the housing of the transmission through the shift fork shaft. If there are several shift forks, several such hydraulic actuators are required. [0003] This type of shifting mechanism has a relatively dispersed structure and adopts hydraulic pressure for shifting. It needs to arrange a special hydraulic oil channel and is of high complexity. [0004] Therefore, how to provide a shift mechanism with a simple structure and a high degree of integration is still an urgent technical problem to b...
