Abstract

The invention discloses a gear selecting and shifting mechanism for an automobile transmission. The gear selecting and shifting mechanism comprises a gear selecting and shifting shaft, and a gear shifting arm assembly and a gear selecting arm which are connected with the top of the gear selecting and shifting shaft, wherein a reverse gear V return spring assembly, a reverse gear V interlocking mechanism and a gear shifting finger are arranged in sequence below a gear shifting shell on the gear selecting and shifting shaft; one end of the gear shifting finger is provided with a gear shifting block for pushing a gear shifting yoke; the reverse gear V interlocking mechanism comprises a locking plate which is hinged on a reverse gear V interlocking mechanism body and a torsional spring which is arranged between the reverse gear V interlocking mechanism body and the locking plate; the end part of the locking plate is provided with a guide groove; and the guide groove on the corresponding locking plate on the gear shifting finger is provided with a locking post. When a gear V is shifted to a gear IV, the locking post is guided by using the guide groove and moves along a guided locus for shifting gears, so that gear shifting is smoother, and the phenomena of clamping and sticking existing in the gear shifting process are avoided.

Description

technical field [0001] The invention relates to the technical field of gear shifting of an automobile transmission, in particular to a gear selection and shifting mechanism of a manual automobile transmission. Background technique [0002] With the continuous development of automobile technology, the shift quality requirements of manual transmissions are also getting higher and higher. At present, the shifting mechanism of manual transmission often has the phenomenon of carding and astringency during the shifting process from 5th gear to 4th gear, resulting in unsmooth shifting and affecting the quality of shifting. As disclosed in Chinese patent application 200810038700.4, a gear selection mechanism for a manual transmission includes a gear selection shaft and a shift fork, and a shift dial that can move the gear shift fork is fixed on the gear selection shaft. A cam is also fixed on the shifting shaft, the top of the cam is provided with a positioning groove, and a fixed ...
