Automobile manual speed changer gear shifting mechanism

Abstract

The invention provides an automobile manual speed changer gear shifting mechanism with good driving comfort. A strip-shaped hole (8) is formed in a position about the middle part of a connecting plate (9); the left end of the connecting plate (9) is rotatablely connected with a gear shifting box (1); the right end of the connecting plate (9) is connected with a weight balancing block (5); a wave-shaped surface (11) is arranged at the front side of the left end of the connecting plate (9); a pulling pin (10) is connected with the right end of a gear shafting rotating arm (6) and is positioned in the strip-shaped hole formed in the connecting plate in a clearance fit way; a locking steel ball assembly (12) comprises a casing (121), a locking steel ball (124), a spring gasket (125) and a spring (123); one end of the casing (121) is provided with an opening (122); the other end of the casing (121) is integrally connected with a flange (120); the locking steel ball (124), the spring gasket (125) and the spring (123) are sequentially assembled in the casing from one end of the opening to the other end of the opening; in addition, the locking steel ball is rotatablely matched with the opening; a part, rotatablely extending out of the opening, of the locking steel ball forms elastic contact with the wave-shaped surface of the front side of the left end of the connecting plate; the casing of the locking steel ball is assembled onto the gear-shifting box.

Description

technical field [0001] The invention relates to an automobile manual transmission, in particular to a shift mechanism of an automobile manual transmission. Background technique [0002] A kind of automobile manual transmission shifting mechanism commonly used in the market at present, see figure 1 and figure 2 , including a shift shaft 4 rotatably and axially movably mounted on the shift box 1, the middle of which is fixedly connected to the upper end of the shift shaft 4, one end is connected to the shift handle through a shift cable, and the other end is connected to the shift handle. The shift arm 6 fixedly connected to the counterweight 5, the shift arm pin 2 installed on the shift box 1, the shift arm pin 2 installed on the shift arm pin 2 and one end movably connected to the upper end of the shift shaft 4 Rotary arm 3. This automobile manual transmission shifting mechanism reduces the shifting impact felt by the shifting handle in the shifting process by assembling...

AI Technical Summary

Problems solved by technology

This automobile manual transmission shifting mechanism reduces the shifting impact felt by the shifting handle in the shifting process by assembling the counterweight 5 on the other end of the shifting arm 6. The problem of its existence is: During the process, the vibration of the counterweight 5 under the inertia of the vehicle will directly cause the vibration of the shift arm 6 which is fixedly connected with it, and then the shift arm 6 will transmit the vibration to the shift handle through the shift cable , making driving less comfortable

When driving on a particularly bad road condition, the vibration of the counterweight 5 due to the inertia of the vehicle is more serious, which not only makes the driving comfort worse, but also makes the shifting arm 6 and the shifting shaft 4 swing more , leading to disengagement, making the safety and reliability of the vehicle poor
