Abstract

The invention discloses a gear selecting and shifting device of an automobile transmission. The gear selecting and shifting device of the automobile transmission comprises a gear selecting and shifting shaft and a support, wherein the gear selecting and shifting shaft extends out of one side of a gear shafting box, an interlock baffle plate is arranged on the gear selecting and shifting shaft in a sleeved mode, the support is arranged on one side of the gear shifting box, and the support is provided with a baffle edge. The interlock baffle plate is composed of a locating pate, a first baffle plate and a second baffle plate, wherein the locating plate is provided with a baffle edge groove, the first baffle plate and the second baffle plate are connected at two ends of the locating plate and both provided with bending portions, the two bending portions are oppositely arranged in an aligned mode, and a shifting head gap is formed between the two bending portions. The interlock baffle is connected with the support in a clamping mode through the baffle edge which extends into the baffle edge groove of the locating plate. The gear selecting and shifting shaft is provided with a gear shifting tooth between the first baffle plate and the second baffle plate, wherein the gear shifting tooth is provided with a shifting head portion, the shifting head portion of the gear shifting tooth extends into a shifting block opening, the gear shifting tooth is fixed on the gear selecting and shifting shaft through a bolt, and a locating part which limits axial movement of the interlock baffle is arranged on the gear selecting and shifting shaft. Compared with the prior art, the gear selecting and shifting device of the automobile transmission has functions of interlocking of all gears and five-gear downshift guiding and avoids the problem of gear disorder of the automobile transmission when a driver puts a gear stick into a gear.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a gear selection and shifting device for a manual transmission of an automobile. Background technique [0002] Automobile transmission gear selection and shifting device is one of the important parts of manual transmission vehicles, and people have put forward higher requirements for its gear selection and shifting performance; Therefore, it is necessary to continuously simplify the mechanism and improve the performance of the car transmission gear selection and shifting device. At present, the interlocking device and the reverse gear lock device for each gear of the commonly used automobile transmission shifting device on the market are separately set up, and the structure is complicated; The lock mechanism does not ensure a smooth downshift from fifth gear. Contents of the invention [0003] The purpose of the present invention is to provide an automobile t...
