Transmission gear locking pneumatic valve

Abstract

The invention relates to a transmission gear locking pneumatic valve which comprises an upper valve body and a lower valve body, wherein the upper valve body and the lower valve body are matched in use; a first air passage and a first air chamber with the open lower end are arranged on the upper valve body, the upper end of the first air chamber is communicated with one end of the first air passage, and a push block is mounted in the first air chamber in a sliding manner; a second air passage and a second air chamber with the open upper end are arranged in the lower valve body, and the upper end of the second air chamber is communicated with the lower end of the first air chamber; a channel penetrating through the lower valve body is formed in the bottom of the second air chamber, and a T-shaped locking pin is inserted into the second air chamber and the channel in a sliding manner and is matched with the push block in use; a boss used for limiting the T-shaped locking pin is arranged at the bottom of the second air chamber, a hollow chamber is formed between the outer side wall of the boss and the inner side wall of the second air chamber, and one end of the second air passage is communicated with the hollow chamber. The scheme can lock the gear of an automobile, reduce the potential safety hazard of driving, and improve the driving safety. The transmission gear locking pneumatic valve has the advantages of being simple in structure and high in use reliability.

Description

technical field [0001] The invention relates to the field of automobile transmissions, in particular to a transmission gear lock air control valve. Background technique [0002] In the whole car, the driver realizes the forward and backward of the whole car by selecting the forward gear and the reverse gear. [0003] In the prior art, many transmissions can adjust a variety of speed ratios when the entire vehicle is moving backwards, so that the entire vehicle has multiple reverse gears, so as to realize the diversification of the vehicle's backward speed, thereby meeting various needs of users. For the above-mentioned multiple reverse gears, there are often one or two gears for realizing fast reverse, which are used to realize the fast reverse of the car. Due to the difference in the transmission control mode, when the driver selects the reverse gear through the transmission, if the driver cannot reverse quickly, he often mistakenly engages the above-mentioned reverse gear...

AI Technical Summary

Problems solved by technology

For the above-mentioned multiple reverse gears, there are often one or two gears for realizing fast reverse, which are used to realize the fast reverse of the car. Different speed control methods, when the driver selects the reverse gear through the transmission, if the driver cannot reverse quickly, he often mistakenly engages the above-mentioned reverse gear that makes the car reverse quickly, resulting in excessively fast reverse speed and driving risks.

And there is no good solution in the prior art
