What is the locking of the wheels in the vehicle ?
Wheel lock in vehicle is one of the most famous system known as ABS, and it is the preferred system which is processed in wheel brakes, and this type of brake has many advantages and advantages that provide the necessary protection. for any car from any slippage while driving, and locking the wheels in general is one of the most dangerous things and therefore there are many accidents, and it also causes many problems for the driver, in especially on difficult roads in case they arise, as it becomes very difficult to control or steer the car.
Advantages of locking the wheels in the vehicle
- ABS is the system most used by car manufacturers in the world, this type works to prevent locking permanently.
- This system helps the driver to control his car and to be able to change direction safely in the event of sudden braking or hard application of the brakes, thus protecting the car from any sudden accident.
- A system that treats the wheels of the car and prevents stopping while spinning when the brakes are pressed. Dealing with modern cars has made it possible to prevent the car from spinning forward or backward.
- Automated system.
- Wheel locking systems vary and differ, and the automatic system is the most famous of these systems, and it is a system that only requires the driver to press the brakes and therefore adjust the parking process.
- The difference between the anti-lock braking system and the wheel locking system is that it is a system whose whole purpose is to eliminate the problems of the wheels stopping and preventing the vehicle from turning when cornering. difficult parking.
- It helps the driver to steer and control the car in sudden stops, and it also helps to control the length and distance of distances, as it reduces the distance the car can travel on the road in the event of a skid.
- ABS also plays the role of traction control On wet, snowy and soft roads, cars seem to slip even with normal brakes, which is caused by the low coefficient of friction of the tires.
- ABS can help deter accidents with advanced technology that can warn drivers of hazards and bring the vehicle to a quick stop when a collision with a vehicle or other object is anticipated.
- This system is used by many car manufacturers, as it offers many advantages for the car and the driver.
Vehicle wheel lock components
- It consists of a valve in the brake line and has three different positions, each with a function.
- In the first position, the valve is open, the pressure from the master cylinder flows through the brakes. In the second position the valve seals the master cylinder brakes, in the third position the valve releases brake pressure.
- It includes a speed sensor located on each wheel of the vehicle and each of them has distinct functions, detecting excessive braking and controlling post-locking.
- There is a pump that plays an important and conscious role in restoring the pressure emitted by the brakes.
- The controller receives information from the speed sensor and controls the valve.
Vehicle wheel locking systems
There are many systems in which wheel lock systems work, the most famous of which is the automatic system, which is a system that simply asks the driver to apply the brakes and adjust the parking process. parking and sliding on surfaces such as snow and gravel are easier to control and adjust the movement of the car.
Reasons why the wheels of the car lock.
There are many reasons that can cause the wheels to lock in the car, and the driver can notice them while driving, therefore, all necessary precautions should be taken, and among these reasons:
- The effect of braking force on the wheels determines their ability to control and control the wheels on the road.
- Applying the brakes too hard can cause major problems, as can putting a little weight on the wheels.
- Frozen water can cause the wheels to lock up if the road is oily or sandy, forming weak adhesives.
- The tires are either poorly designed or outdated.
Brake system faults ABS:
- Many problems can arise due to your consumption of a large amount of braking energy, because this system mainly depends on the brakes, but the driver does not feel them.
- The use of this type of system is increasing due to the strain placed on the car engine, especially at high speeds.
What causes the rear wheels to lock while driving?
- The driver can be exposed to many problems, but the most serious of these is wheel lockup. The process of locking the rear wheels therefore depends on the driver’s ability and intelligence to control this and the extent of their experience.
- The vehicle turns and the driver is unable to control it.
- Locking the front wheels while driving is much less dangerous than locking the rear wheels, and locking causes the car to lose balance and control.
- The driver loses the ability to steer the vehicle.
How does the wheel locking system work?
- The system monitors the wheel’s response to pressure on the brake fluid and reduces its rate, so that there is no binding condition, then increases the pressure several times to continue the parking brake process , and the system continues this process to reduce or increase the pressure.
- It prevents wheel lockup, but does not prevent accidents, does not affect braking force, and works when the wheels are locked.
- The system follows the vehicle’s conventional brakes and the system also reduces the stopping distance when detecting a part.
- The light comes on when there is a system fault and it does not affect the conventional brake system.
The difference between self-propelled anti-lock wheels
We will find out many differences between ordinary anti-lock wheels and when using the electronic anti-lock system (ABS), and the driver himself will notice them as follows:
- The rate of repetition by the driver independently is three to four times per second, compared to 20 to 30 times per second, as in the case of ABS.
- Hole parking affects all wheels, but ABS is applied to each wheel depending on the need for locking.
- The electronic anti-lock braking system has the remarkable characteristic of being able to reduce stopping distance at the highest rate of tire-to-road contact, maximizing the use of braking force.
How to repair the brake system
There are several instructions that should be taken when you feel there is a problem with the brake system.
- The ABS fuse must be checked first, and if damaged, it must be replaced directly.
- Check the brake fluid level to see if it is too low or too high, an oil leak could be the cause.
- Sometimes the cause of the light is a minor electrical fault in the car, to be sure, turn off the engine and unplug the car battery cable, then wait 30 minutes and plug it back in and crank the engine again.
