Gear shifting interlocking device of automobile manual transmission

Abstract

A gear shifting interlocking device of an automobile manual transmission comprises shift fork shafts, shift fork shaft locking blocks, a steel ball limiting lock, a steel ball limiting lock fixing plate and shift fork shaft positioning plates. The number of the shift fork shafts is matched with the number of gears of the transmission. All the shift fork shafts are in a parallel arrangement state, the reciprocation trails of the shift fork shafts are limited through the shift fork shaft positioning plates, and each shift fork shaft is provided with one shift fork shaft locking block. The shift fork shaft locking blocks and the steel ball limiting lock are assembled in a matched mode. The steel ball limiting lock and the shift fork shaft positioning plates are assembled through the steel ball limiting lock fixing plate. The shift fork shaft positioning plates are fixed to a transmission shell. The gear shifting interlocking device has the advantages of being simple in structure and convenient to assemble, the interlocking function between different gears in the gear shifting process is guaranteed, besides, the assembling difficulty of the components is lowered, working efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to an automobile manual transmission, in particular to an automobile manual transmission shift interlocking device, which belongs to the technical field of automobile transmissions. Background technique [0002] With the rapid development of the automobile industry, consumers' requirements for automobile performance are constantly increasing. Automobile manufacturers are striving to improve product quality and pay more attention to the control of manufacturing costs. Therefore, simplifying the structure of each assembly part and reducing the difficulty of assembly goals pursued by designers. [0003] For automobile manual transmissions, most of the shift interlock devices in the prior art are installed on the operating mechanism of the transmission. For example, a shift device of a mechanical transmission includes a shift arm, a shift arm, a shift A gear shaft, a gear shift swing arm arranged on the gear shift shaft, and a gear s...

AI Technical Summary

Problems solved by technology

Although the shifting device of the mechanical transmission has the advantages of compact structure, flexible and convenient shifting, accurate shifting, no shifting, no random shifting, and high transmission efficiency, due to the complex structure of the shifting shaft, it is difficult to guarantee the machining and assembly accuracy, and It cannot be applied to the operating mechanism where the shift fork shafts are far apart; at the same time, because the interlock plate is not fixed, the interlock plate interferes with the shift fork block when the shift shaft and the transmission assembly are assembled, which increases the difficulty of assembly and reduces the Work efficiency, improve production cost
