Blocking the car

The front part of the car is said to be the front and lower part of the car, which is responsible for various tasks such as suspension or good handling of the car in potholes, bumps and turns of the road. . The maintenance of this part of the car is the responsibility of the manufacturer.

The suspension system includes shock absorbers and the rear wheels of the car, but in the front suspension system, we only refer to the front part of the car, which includes the steering wheel and steering shaft. We all know that the front wheels have the main task and role in driving the car in different directions, that's why the car suspension system in the front is much more and more important than the rear part of the car, including the car steering system. It can also be called separately, the front of the car.

These parts are spherical in shape and are related to the steering system of the car, and their task is to prevent friction between the two parts and their smooth and smooth movement. Sibak failure symptoms: Steering wheel vibration during movement and when turning the steering wheel, excessive clearance of the steering wheel, pulling the steering wheel to one side, the steering wheel not returning to its original position after turning, a rattling sound is heard when crossing a bump, the amount of the steering wheel is reduced. The car's handling, the car's failure to move in a straight line and causing deviation during movement, wear on the front wheels

The suspension system or device is a part of the car that prevents vibrations and shocks from entering the suspended part of the car, which includes the chassis, room and passengers along with its accessories. Suspension system parts include spring, shock absorber, sprung mass and unsprung mass. The two tasks performed by the suspension system include reducing the vibrations and oscillations of the roads and paths, and the other is the effective collision of the surface of the tires with the surface of the roads and the path so that the least pressure is applied to the car and its accessories.

The central axis of a wheel or gear is called an axle. Sometimes the axle may be held in place by a bearing or bushing on the inner surface of the gear or wheel hole to allow the gear or wheel to rotate freely. The car steering system is considered one of the main components of the car's suspension, which itself includes the parts that are responsible for handling and steering the car. The importance of the car's steering system is as important as the car's engine and gearbox. The parts and components of the steering wheel include the steering wheel, box and steering shaft.

The spring aid is a part that is installed on the axis of the wheels and near them to reduce and control the oscillations and vibrations resulting from the movement of the car on uneven roads. One end of the shock absorber is connected to the car room and the other end of the shock absorber is connected to the part of the suspension system. Spring movements increase and decrease the length of the shock absorber. Symptoms of shock absorber failure The shock absorber has a leak, the car is lying on one side, the car dives forward when braking, the wheels constantly go up and down on uneven surfaces, the tires are worn, the car is pulled to one side, the noise when crossing bumps. >

Springs are parts that have an elastic or elastic state and are collected or stretched due to the pressure of an external force, and after the pressure is removed, the spring returns to its original state. The springs used in cars can be physical, gas or liquid, which are divided into mechanical, air or pneumatic and oil or hydraulic springs, respectively. Springs are also responsible for reducing pressure and vibrations when driving on uneven roads.

The hand dog is like a hinge that is used to help turn the wheel on the steering wheel axis and it rotates on the hand dog shaft. The duty of maintaining the wheels is also the responsibility of the dog hand. The brake discs and the steering wheel of the car and the connections of the wheels and the wheel hub are attached to the dog hand and in the car with MacPherson suspension, the helper shaft is also connected to it.

The hand jack is the part to which the car steering wheel is connected, and the auxiliary shaft and the steering shaft are connected to the hand jack by screws.

Trays are actually arms that are responsible for connecting the suspension system to the chassis. The trays are connected to the car chassis by bushings, and the connection to the car wheel is done through the cup and ball connection.

The balance beam is used in most cases to increase the balance of the car and also to prevent the car from turning to the left. This part is responsible for distributing the force between the wheels when passing the turns and prevents the car from bending to one side.

Paying attention to the signs of failure of the front part: the failure of the parts of the front part of the car is accompanied by symptoms. Of course, some signs are common among front parts. According to these signs and checking them, it is easy to diagnose the fault and fix it. Visual inspection of front: in this method, after driving test and inspecting the wheels, opening them and visual inspection, the defect can be found and fixed. Using a diagnostic device: Most of these devices are available in car technical examination centers, and by testing the car, you can find out if the front parts, especially the aids, are healthy or not.

This piece is installed between two lower trays. When the car moves in the turns, the car room tilts to the outside of the turn, and as a result of this, the lower trays move in the opposite direction and rotate the balance rod, and the balance shaft shows resistance due to the rotation, which in The result of this hard action is the tightening of the car suspension system when the car turns, and as a result of this process, the car room is less tilted and curved.
