What are the three locking devices of the gearbox?

1) It is equipped with a self-locking device to prevent the transmission from automatically shifting and automatically disarming. (2) It is equipped with an interlock device to ensure that the transmission will not be shifted into two gears at the same time, so as to avoid the engine from stalling or breaking. (3) It is equipped with a reverse gear lock to prevent mistaken reverse gear shifting, otherwise a safety accident will occur.

1) Self-locking device: self-locking steel ball and self-locking spring 2) Interlocking device: mainly composed of interlocking steel ball and interlocking pin 3) Reverse lock:

Consists of reverse gear lock pin and reverse gear lock spring (1) self-locking device 1) the self-locking device of most transmissions is composed of self-locking steel ball 1 and self-locking spring 2) the upper surface of each fork shaft is distributed with three grooves along the axial direction, and when any fork shaft together with the fork axial moves to the position of neutral gear or a certain working gear, there must be a groove that is exactly aligned with the self-locking steel ball. Therefore, the self-locking steel ball is embedded in the groove under the action of the self-locking spring pressure, and the axial position of the fork shaft is fixed, so that the fork and the sliding gear (or coupling sleeve) are also fixed in the neutral gear or a certain working gear, and cannot come out by itself. 3) When shifting, the driver exerts a certain axial force to the fork shaft, overcomes the pressure of the self-locking spring 2 and extrudes the steel ball from the groove of the fork shaft and pushes it back into the hole, and the fork shaft and the fork move axially.

2) Interlocking device 1) It is mainly composed of interlocking steel balls and interlocking pins. The interlocking pin is housed in the hole of the middle fork shaft and its length is equivalent to the radius of the fork shaft diameter minus the interlocking steel ball, which is housed in the transverse hole of the transmission cover. 2) When in the neutral position, the left and right fork shafts have grooves with a depth equivalent to the radius of the steel balls at the steel balls, and the middle fork shafts have grooves on the left and right, and there are holes for installing lock pins in the grooves.

3) This interlock device can ensure that the driver can move either fork shaft to shift the transmission only when it is in neutral position. If one fork shaft is moved and is in gear, the other two fork shafts are held in neutral position by an interlock device and can no longer be moved axially. (3) Reverse gear lock 1) The function of the reverse gear lock is that when the driver hangs the reverse gear, he must exert a large force on the gear lever before he can change the reverse gear and play a reminder role to prevent the reverse gear from being hung by mistake.

The transmission is mostly equipped with a spring-lock pin reverse lock. 2) The reverse lock is generally composed of a reverse lock pin and a reverse lock spring. The rod part of the reverse lock pin is equipped with a reverse lock spring, and the nut at the right end of the reverse pin can adjust the preload of the spring and the length of the reverse lock pin.

3) When the driver wants to hang the reverse gear, he must use a large force to compress the reverse spring at the lower end of the gear lever, and push the reverse lock pin to the right before the lower end of the gear lever can enter the groove of the reverse paddle to toggle.

1. Reverse gear fork shaft and push into reverse gear.

Hello is a pleasure to answer for you self-locking, interlocking, reverse gear lock thank you, if I want to be helpful to you, I wish you a pleasant experience.

1) Self-locking device The so-called self-locking prevents it from automatically generating an axial direction.

Movement causes automatic gear or automatic disgearing.

2) Interlock device The function of the interlock device is to prevent two fork shafts from moving at the same time, that is, when a fork shaft is moved axially, the other fork shafts are locked, so as to prevent two gears from being hung at the same time.

1, the transmission control mechanism, including the lever, the gear cable, the gear shaft, the gear fork, the locking mechanism, 2, the role of the control mechanism: for the driver to switch gears, 3, the self-locking device is used to prevent in the process of vehicle bumps, automatic disgear or automatic gearing, interlock device, to prevent the automatic transmission from being out of order, both to prevent the transmission from being hung into two or more gears at the same time, the reverse gear device, with the reverse gear located in front of the first gear in the form of arrangement, to prevent the driving process when hanging a gear, accidentally hooked into the reverse gear.

The function of the gearbox self-locking device is to press the steel ball into the corresponding groove after the car is hung on the gear, and the spring is pressed into the corresponding groove to prevent the car from automatically jumping or taking off the gear.

The self-locking device is composed of a free lock steel ball and a free lock spring, and his main role is that after the car is hung up on the gear, the spring presses the steel ball into the corresponding groove to prevent the car from automatically jumping or taking off the gear, when shifting, the lever exerts force to the fork shaft to make the steel ball overcome the pressure of the spring and enter another groove, and then lock another gear.

Don't underestimate the self-locking device, the location of this device reduces the accident rate of automobiles a lot and protects the rights and interests of consumers. In layman's terms, it's actually the P-block position. That is, the parking gear, which improves the safety of the vehicle.

The self-locking device consists of a self-locking steel ball and a self-locking spring, and three grooves are distributed axially on the upper surface of each fork shaft. When any of the fork shafts are moved axially to neutral or a working position along with the forks, there must be a groove that is exactly aligned with the self-locking steel ball. As a result, the steel ball is embedded in the groove under spring pressure, and the axial position of the fork shaft is fixed, so that the fork and the sliding gear (or coupling sleeve) are also fixed and cannot come out on their own.

1. Transmission.

The function of the interlock device: to prevent automatic shift or disgear during the movement of the car, in which the disgear is to take the gear back into neutral. 2. Automobile transmission:

It is a transmission device designed to coordinate the engine speed with the actual travel speed of the wheels to get the most out of the engine. 3. Working principle: The self-locking device is composed of self-locking steel balls and self-locking springs, and the upper surface of each fork shaft is along the axial direction.

Distribute three grooves. When either fork shaft moves axially to neutral along with the fork.

Or there must be a groove in a certain working position that is just aligned with the self-locking steel ball. The steel ball is embedded in this groove under spring pressure, and the axial position of the fork shaft is fixed, so that the fork and the sliding gear (or coupling sleeve) are also fixed and cannot come out on their own.

The function of the transmission self-locking device is that after the car is hung on the gear, the spring will press the steel ball into the corresponding groove to prevent the car from automatically jumping or taking off the gear, when shifting, the lever exerts force to the fork shaft to make the steel ball overcome the pressure of the spring into another groove, and then lock another gear to prevent the car from moving in the process, the situation of automatic shift or disgearing.

The function of the transmission self-locking device is that after the car is hung on the gear, the spring presses the steel ball into the corresponding groove to prevent the car from automatically jumping or getting out of gear, when shifting, the lever exerts force to the fork shaft to make the steel ball overcome the pressure of the spring and enter another groove, and then locks another gear, so as to prevent the car from moving in the process, the situation of automatic shift or disgearing occurs.

It can control a gear when moving forward or backward, the sliding gears of other gears remain unmoving, lock them and prevent them from automatically returning to the original position during driving, which can avoid random gear jumping.

The self-locking device is composed of a free lock steel ball and a free lock spring, and the working principle is that the spring presses the steel ball into the corresponding groove, that is to say, there will be three grooves on the fork shaft, and there is bound to be a groove that is aligned with the self-locking steel ball with the grinding plate, so that it can play a role in preventing the car from automatically jumping or taking off gear. This device can greatly reduce the accident rate of automobiles and ensure the safety of drivers and passengers. The car transmission is used to change the engine speed and torque.

After the car is hung on the gear, the spring presses the steel ball into the corresponding groove to prevent the car from automatically jumping or taking off the gear, when shifting, the lever exerts force to the fork shaft to make the steel ball overcome the pressure of the spring and enter another year-old groove, and then locks another gear, and the anti-hall quickly stops the car in the process of traveling, and the situation of automatic shift or disgear occurs.

1.The self-locking device consists of a free-locking steel ball and a free-locking spring. Its main function is to press the steel ball into the corresponding groove after the car is in gear, preventing the car from automatically jumping or shifting gears.

When shifting gears, the lever applies force to the fork shaft, causing the ball to enter another groove against the pressure of the spring, and then locks the other gear.

2.Don't underestimate the self-locking device. The location of this device reduces the accident rate of the car and protects the rights and interests of consumers. Generally speaking, it is actually a matter of which is the p position. That is, the parking gear, which improves the safety of the vehicle.

3.The self-locking device is composed of a self-locking steel ball and a self-locking spring, and the upper surface of each fork shaft is axially distributed with three grooves. When any fork shaft moves with the fork shaft to the spike block neutral position or a certain working position, there must be a groove that is just aligned with the self-locking steel ball.

Then, the steel ball is embedded in the groove under the pressure of the spring to fix the axial position of the fork shaft, so that the fork is fixed with the sliding gear (or joint sleeve) and cannot come out on its own.
