A vehicle transmission control device

Abstract

The invention discloses a vehicle transmission operating control device. The vehicle transmission operating control device comprises a gear selecting / shifting device assembly and a neutral position locator. A vehicle transmission comprises a synchronizer assembly. A synchronizer compression spring in the synchronizer assembly is pressed on a synchronizer pin in a synchronizer sliding gear sleeve groove, and neutral gear positioning of a synchronizer is achieved. The gear selecting / shifting device assembly comprises a shift fork shaft connected with a shift fork, a gear shifting rod connected with a shift head, and a shift fork shaft locator. The shift fork shaft locator is pressed in a shift fork shaft groove through a shift fork shaft compression spring, and neutral gear positioning of the shift fork shaft is achieved. The neutral position locator comprises a shell fixed in the vehicle transmission, a self-locking compression spring arranged in the shell, a self-locking pin arranged on the shell in a sliding manner, and a positioning cam fixed to the gear shifting rod. A surface work part of the positioning cam is provided with a V-shaped protrusion, and a positioning groove is formed in the top end of the V-shaped protrusion. The self-locking compression spring is pressed on the self-locking pin in a matched manner, the self-locking pin is arranged in the positioning groove, and the neutral gear positioning of the shift head is achieved.

Description

technical field [0001] The invention relates to a transmission control device, in particular to a vehicle transmission control device. Background technique [0002] The selection / shift performance of the transmission is not only related to the structure of the transmission itself and the manufacturing precision of the parts, but also has a great relationship with the structure of the operating mechanism, the direction of the cable, and the efficiency of the entire selection / shift system. If any link fails to meet the requirements, it will directly affect the selection / shift performance. [0003] The transition between the gears of the transmission with good shifting performance is very smooth, and the gap between the shifting head in the gear and in the neutral gear is required to be as small as possible. During the shifting process of the transmission, the maximum disengagement force needs to be moderate. If it is too large, it will not be easy to disengage, which will aff...

Problems solved by technology

There are several impacts during the shifting process of the traditional operating device, including the first impact of the shift fork shaft positioner and the shift fork shaft, the second impact of the positioner on the synchronizer and the sliding tooth sleeve of the synchronizer, and the synchronization of the synchronizer The third impact occurs between the ring and the coupling teeth, and the change of gear resistance is more complicated, which is manifested by poor shift smoothness
