Embodiment 1

[0022] The gear locking mechanism of the transmission in this embodiment includes a telescopic locking mechanism 5 fixed on the gearbox body 1 and a shift shaft 2 with a limit linkage mechanism. The telescopic locking mechanism 5 cooperates with the limit linkage mechanism to realize switching Locking of gear shaft. see figure 1 .

[0023] The retractable locking pin mechanism 5 includes a locking pin 3 , a return spring 8 and a pneumatic cylinder 16 connected with the locking pin 3 . Wherein, the cylinder body of the pneumatic cylinder 16 is fixed on the gearbox body 1; the lock pin 3 is connected with the lower end of the piston 17 of the pneumatic cylinder 16 as a whole, the upper chamber of the pneumatic cylinder 16 is the locking chamber 6, and the lower chamber of the pneumatic cylinder is the return chamber. A position air chamber 7 and a return spring 8 are installed in the return air chamber 7, and the pneumatic cylinder 16 communicates with the pressure air source ...

Embodiment 2

[0033] see Figure 4 , figure 2 , the difference between this embodiment and Embodiment 1 is that the pressure air source control system includes an air storage tank 21 and a two-position four-way solenoid valve 12, the solenoid valve control switch 11 is linked with the clutch pedal; the air storage tank 21 passes through the pipeline The two-position four-way solenoid valve is connected with the pneumatic cylinder 16, and the delay disconnection trigger 13 is connected in series between the electric control end of the solenoid valve and the control switch 11. Release the clutch pedal, the control switch is disconnected, the solenoid valve returns, the air storage tank 21 is connected to the locking chamber 6 of the pneumatic cylinder, the returning air chamber 7 is exhausted, and the lock pin 3 is stretched out at the locking position; step on the clutch Pedal, the control switch is closed, the solenoid valve shifts and changes direction, the air storage tank 21 is connect...

Abstract

The invention relates to a car hand transmission grade-position locking arrangement, which consists of telescoping lockpin system on the transmission case and shift rotation shaft within stopping linked system, wherein the telescoping lockpin system mates the stopping linked system on the transmission shaft, which is set on the transmission case corresponding to the stopping linked system. The arrangement is easy to reequip and operate, which contains high reliability and simple structure.

Description

technical field [0001] The invention relates to a gear locking device of a transmission, in particular to a gear locking device for a manual transmission of an automobile. Background technique [0002] Mechanical transmissions are widely used in modern cars. A mechanical transmission usually consists of a gearbox, a transmission gear and a shifting mechanism, wherein the shifting mechanism includes a shift fork, a shift shaft, a shift lever and a shift shaft connected to a shift rocker arm. . In order to prevent the automatic disengagement of the transmission, self-locking and interlocking devices are usually arranged on the shift fork shaft and the shift shaft. become. Under normal circumstances, it can prevent the automatic de-shifting of the transmission. However, under certain working conditions, such as when the vehicle is going downhill at a certain speed, the throttle is loosened, the engine speed drops, and the adapter sleeve cannot keep up with the speed of the ...
