Hard rod type gear-changing system for transmission gear

Abstract

The invention discloses a hard rod type gear-changing system for a transmission gear, which is a single-hard-rod gear-changing system comprising a control mechanism, an expansion link assembly, a gear-changing assembly and a gear-selecting assembly; the control mechanism is connected with the expansion link assembly through a bulb or a revolute pair, the expansion link assembly is respectively connected with the gear-changing assembly and the gear-selecting assembly through a bulb or revolute pair, and a plurality of mounting hole positions are arranged on the end part of the expansion link assembly. By adopting the technical scheme of the invention, the technical problem of poor self-regulation adaptability of the hard rod type gear-changing system in the prior art can be effectively solved; meanwhile, the hard rod type gear-changing system also has the advantages of enabling the gear-changing system to have larger regulation allowance (+ / -80) because the installing hole positions are additionally arranged on the tail end of an expansion link, further improving the gear-changing handfeel, increasing the gear-changing smooth property, reducing the running out of gear probability and decreasing the shake amount and the out of gear probability of the gear-changing handle due to poor road conditions.

Description

technical field [0001] The invention relates to the technical field of manufacturing a transmission shift system, in particular to a hard lever type shift system for a gearbox. Background technique [0002] At present, in the field of manual transmission shift system manufacturing technology, the shift system mostly adopts a hard rod shift system; the hard rod shift system in the prior art has the following technical problems due to poor self-adjustment adaptability: [0003] 1. The hard rod shift system in the prior art has poor self-adjustment adaptability; [0004] 2. Adopt the hard rod type gear shifting system in the prior art. When the road conditions are poor, the gear shift handle will shake easily, and even cause the shifting of gears in severe cases, endangering the safety of vehicles and people. Contents of the invention [0005] The technical problem to be solved by the present invention is that the self-adjustment adaptability of the hard rod shift system in ...
