Gear-shifting control mechanism assembly of transmission

Abstract

The invention relates to a gear-shifting control mechanism assembly of a transmission. The assembly comprises a gear selecting and shifting base, a gear selecting rocker arm, a gear shifting rocker arm, a gear selecting and shifting shaft, a first gear and second gear shifting fork combination part, a third gear and fourth gear shifting fork combination part, a fifth gear and R gear shifting fork combination part, a first gear selecting return spring, a second gear selecting return spring, a gear selecting and shifting push block, a gear shifting interlocking plate, a first gear and second gear shifting push block, a third gear and fourth gear shifting push block, a fifth gear and R gear shifting push block, a gear selecting guide bolt, a gear shifting guide bolt, a gear shifting locating pin and a guide block with a groove shaped like a Chinese character 'wang'. According to the technical scheme, in a control system, the gear shifting locating pin is added, and therefore the gear shifting suction feeding can be improved; the guide block with the groove shaped like the Chinese character 'wang' is designed, and therefore gear shifting can be smooth, the gear shifting track can be uniform and the gear shifting quality can be improved; the gear shifting interlocking plate is adopted, and therefore the design of a box body and a shifting fork shaft can be simplified, and the assembly technology can be simplified; and a compression spring is adopted for gear selecting returning and has the advantages that the manufacturing errors are small and the gear selecting returning effect is good compared with a traditional torsion spring.

Description

technical field

[0001] The invention belongs to the technical field of transmissions, in particular to an assembly of a gear shifting control mechanism of a transmission. Background technique

[0002] The shift control mechanism of the transmission is mainly used to transfer the force and motion acting on the gear selection and shift rocker arm to the combined tooth sleeve of the gear set to realize the shift action.

[0003] With the development of automobile technology, customers have higher and higher requirements on the performance of vehicle gear shifting. Obvious effects have become key indicators for customers to evaluate vehicle performance.

[0004] The gear shifting mechanism of the transmission in the prior art realizes gear selection and gear shifting by driving the shifting block through the gear selection and gear shifting rocker arm. There is no slotted design, that is, there is no guide in the gear selection process, which is not conducive to the improvement...
