What kind of driving safety accidents can be caused by transmission failure?

Gearbox, mainly refers to the gearbox of the car, the gearbox can be divided into manual and automatic two kinds, of which the manual gearbox is mainly composed of gears and shafts, and the principle is to produce variable speed and torque through different gear combinations; The automatic transmission (AT) consists of a hydraulic torque converter, planetary gears, a hydraulic shift system and a hydraulic control system. The principle of automatic transmission is to achieve variable speed and torque through fluid transmission and gear combination. <>

So what are the consequences of a gearbox failure?

The first is that the gear engine stalls, which is mainly manifested in the fact that after starting the car, when changing from P or N gear to other gears of the car, the engine will stall, or when the brakes are stepped on during driving, the engine will stall. This could be damage to the lock-out solenoid valve, or damage to the lock-up control valve hairpin. If several times the gear will cause the engine to stall, then it is necessary to check whether the impact of the gear is large, if the impact of the gear is relatively large, this time to fight the rescue**.

Furthermore, the gearbox will be locked, which is manifested in the normal driving of the car, refueling can only see that the speed is very high, but the speed of the car is very slow, if the speed of the brakes is reduced to a certain extent, at this time, it is changed to manual, and it is found that it cannot be upshifted or lowered when hanging in a gear, that is to say, the transmission is locked in a certain gear at this time, and it can not be shifted. This is mainly due to incorrect input and output signals of the gearbox, or faults caused by poor wiring. Once this kind of failure occurs, it is easy to dispose of yourself in a dangerous environment in the process of driving, because in urban areas and other places where there are many vehicles, the speed of the vehicle can not be reduced or the speed can not be raised, and traffic accidents are easy to occur.

Another is the phenomenon of not going to the car in gear, which is manifested in the fact that after the car starts, the gear is hung D or R gear, at this time, the vehicle has no response after releasing the brakes, and the vehicle will not move forward. This could be due to damage to the transmission input shaft or reverse clutch, as well as damage to the DR brakes.

This can cause the vehicle to suddenly become unmoving. The gearbox is divided into manual and automatic, which is the main mechanism for transmitting power, and if there is a problem, it will cause the vehicle to suddenly lose power, resulting in the vehicle being unable to continue driving, and it is very dangerous if it breaks down at high speed.

If the gearbox fails, the driver may not be able to slow down the speed of the car during driving, and there may be a situation that the speed cannot be increased, and the driver cannot control the speed, and the engine may stall.

It may cause the vehicle to suddenly appear out of gear while driving, with a spike in revs, and in the case of reversing, no power.

The gears are locked, the engine is turned off, the car is unresponsive, etc. Gear locking means that you can't change gears, and the speed of the vehicle is limited, and it is easy to complete the rear-end accident caused by driving at the specified speed. When the engine goes out, the car goes out, and it may complete a chain of rear-end collisions.

As for the unresponsiveness of the car, it is more serious, and it may not be avoided in time, and it will hit pedestrians. So be sure to check the gearbox regularly.

The first is that the gear engine stalls. Or maybe the gearbox will lock up. The car slows down. It may also cause the phenomenon of not moving away from the car when in gear. Nothing happens after releasing the brakes. There is a possibility of damage to vehicle parts.

The gearbox is faulty, the gear is difficult, and when the gear lever is controlled, the gear is very laborious, and the gear cannot be smoothly entered; Or there is a tooth slapping sound when the gear is in gear, and it can't be put in gear when it is serious.

Automatic shifting, one is to lift the accelerator pedal slightly while driving, and the gear will jump back to the neutral position; The other is that when the uphill load increases, the gear immediately jumps back to the neutral position, in this case, if the re-hanging gear is not hooked, it is easy to form a slippery slope and a serious accident occurs.

First, the car will stall when the gear is in gear or the brakes will stall during driving, which is extremely dangerous in the uphill and downhill sections.

Second, the gearbox is locked, and the speed is very high but the acceleration is very slow, which will shorten the distance with the rear car, resulting in a rear-end collision.

Third, don't go to the car when you get into gear. Even if the gear is engaged, the car will not move forward, affecting the normal driving of the vehicle behind it.
