Gear selecting and shifting control mechanism of gear selecting and shifting device in automobile gearbox

Abstract

The invention relates to a gear selecting and shifting control mechanism of a gear selecting and shifting device in an automobile gearbox. The gear selecting and shifting control mechanism comprises a control shaft, a first bearing supporting seat, a second bearing supporting seat, a gear shifter casing, a gear shafting guide block, an M-shaped gear shafting groove, a gear shifting groove in the shape of a Chinese character 'wang', a V-shaped gear shifting return block, a first gear shifting finger and a second gear shifting finger, wherein the gear shifter casing, the first bearing supporting seat, the first gear shifting finger, the M-shaped gear shifting groove, the gear shifting groove in the shape like a Chinese character 'wang', the V-shaped gear shifting return block, the second gear shifting finger and the second bearing supporting seat are integrally welded; a control shaft is mounted in the second bearing supporting seat and the first bearing supporting seat; the gear shifting guide block is welded to the control shaft, and is matched with a guiding waist-shaped hole. The gear selecting and shifting control mechanism disclosed by the invention is small in gear shifting force, simple in structure, convenient to mount and replace and simple in forming process, and has favorable selecting and shifting hand feel.

Description

technical field [0001] The invention relates to a gear selection and shift control shaft mechanism for controlling all gears inside an automobile gearbox, in particular to a gear selection and shift control mechanism for a gear selection and shift device inside an automobile gearbox. Background technique [0002] The automobile gearbox control device is an important component in the automobile gearbox. If it is damaged during the driving process of the automobile, it will easily lead to traffic accidents, and even cause the tragedy of car crash. At present, the shifter assembly of the automotive transmission control device on the market generally has the following two structures: [0003] 1. Other components such as the control shaft 1 and the bearing support seat 2 are fixed structures, and there is no relative movement between them. The disadvantage of this structure is that the selection force overcome when selecting gears is large, and it is easy to cause the phenomenon ...
