Problems solved by technology
[0005] In the above-mentioned reverse gear locking device, although it can prevent the vehicle from mistakenly engaging reverse gear during high-speed driving, the operation process is realized manually, and the degree of automation of the device is not high.
And because it is manually operated, it is inevitable that there will be mistakes. There is a situation where the gear is directly changed from the highest speed forward gear to the 3 / 4 gear space and then to other forward gears or reverse gears, so there are certain safety hazards.

Embodiment 1
[0023] Such as figure 1 and figure 2 As shown, the gear locking mechanism in this vehicle is made up of parts such as gear selection frame 1, gear selection housing 2 and electromagnetic valve.
[0024] Specifically, the gear locking mechanism is arranged between the gear selection frame 1 and the gear selection housing 2 , the gear selection frame 1 is hinged on the vehicle body, and the electromagnetic valve is fixedly connected in the gear selection housing 2 . When the vehicle is running at a high speed, the high-speed signal is transmitted to the solenoid valve, and the solenoid valve is energized so that the valve core 3 extends out of the gear selection housing 2 and presses against the gear selection frame 1 to prevent the gear selection frame 1 from rotating. In this way, the gear position is locked, and the gear cannot be directly adjusted, which prevents the occurrence of the reverse gear by mistake; The gear selection frame 1 is disengaged, so that the gear sele...

The invention provides a gear locking mechanism in a vehicle and belongs to the technical field of vehicle manufacture. The problems of low automation, low security and the like of the traditional reverse gear locking devices are solved. The gear locking mechanism in the vehicle is arranged between a gear selection frame and a gear selection casing, wherein the gear selection frame is hinged on the vehicle body; the mechanism comprises an electromagnetic valve fixedly connected in the gear selection casing; when the electromagnetic valve is electrified, the valve core of the electromagnetic valve extends out of the gear selection casing and props against the gear selection frame to prevent the gear selection frame from rotating; when the electromagnetic valve is in power off state, the valve core of the electromagnetic valve retracts and separates from the gear selection frame. The mechanism has the advantages of high automatic degree, good safety performance and the like.
Description
technical field [0001] The invention belongs to the technical field of vehicle manufacturing, and relates to a gear lock mechanism, in particular to a gear lock mechanism in a vehicle. Background technique [0002] When the vehicle is running at high speed, it is not allowed to put the reverse gear directly, because this operation will cause the gears in the gear transmission of the vehicle to wear or collapse, which will directly affect the service life of the gear transmission of the vehicle, and will also reduce the driving experience. Safety performance, prone to traffic accidents. [0003] Therefore, to prevent the vehicle transmission from being directly transferred from the forward gear position to the reverse gear position and mistakenly engaging the reverse gear, people have carried out various designs on the gear device of the vehicle. The operation of inverting the reverse gear by mistake has been reduced, but the problem of inverting the reverse gear by mistake ...
