The main components connecting the wheels of a car chassis are the wheel hub, tires, suspension system, braking system, steering system, etc. Here is a detailed introduction:

Car wheel hub. Responsible for connecting the wheels and axles, transmitting power.

Tires. Directly in contact with the road surface, supporting the weight of the car and providing traction.

Suspension system. Connect the wheels to the vehicle body, absorb road bumps, ensure that the wheels always stay in contact with the ground, and provide stable driving performance.

Braking system. Ensure car safety by converting the vehicle's kinetic energy into thermal energy through components such as brake drums or discs, brake pads, and brake fluid, to slow down or stop the car.

Steering system. Enable the driver to control the direction of the car, including components such as steering wheels, steering racks, steering knuckles, and power steering pumps.

These components work together to ensure that the car can travel safely and smoothly on the road.

After replacing the ball joint of the pull rod, it is usually necessary to perform four-wheel alignment.

This is because the replacement of the pull rod ball joint may affect the vehicle's suspension system, causing displacement at the connection. If four-wheel alignment is not carried out, the vehicle may experience problems such as driving deviation, steering wheel misalignment, tire wear, heavy steering, and inability to automatically return. Four wheel alignment includes adjusting parameters such as caster angle, camber angle, front wheel camber angle, front wheel toe in, and rear wheel toe in to ensure good driving performance and reliability of the vehicle.

However, if other chassis components (such as shock absorbers, connecting rods, lower control arms, subframe, etc.) are not replaced during the process of replacing the tie rod ball joint, and the vehicle does not experience any abnormal conditions such as uneven wear or running, then immediate four-wheel alignment may not be necessary. However, for safety reasons, it is best to perform four-wheel alignment after replacing the rod ball joint to avoid potential risks.

The purpose of automobile tie rod is an important connector to link the two rear wheels of automobile. It connects the left and right steering arms. One can synchronize the two wheels, and the other can adjust the toe in. It is also an important part to ensure the safe driving of automobile.

The functions of automobile vertical pull rod are as follows:

1. The tie rod of the rear axle is located in the rear axle of the car, which is an important connector to link the two rear wheels of the car, and also an important part to ensure the safe driving of the car;

2. The longitudinal tie rod of automobile rear axle is used to stabilize the rear axle. The rear axle refers to the bridge behind the car;

3. If the front axle is not the drive axle, then the rear axle is the drive axle. At this time, in addition to the bearing function, it also plays the role of driving, deceleration and differential. If it is four-wheel drive, it is generally equipped with a transfer gear in front of the rear axle.

Symptoms of car ball head needing to be replaced:

1. If the front wheel ball joint of a car is broken, the following symptoms will appear: bumpy road, cluttering; the car is unstable, swinging left and right; the brake deviates; the direction fails;

2. The ball head is easy to break when it is subjected to impact load due to too large clearance. Repair as soon as possible to avoid danger;

3. The outer ball joint refers to the hand pull rod ball joint, and the inner ball joint refers to the steering machine pull rod ball joint. The outer ball and the inner ball are not connected together. They have to work together. The ball head of the steering machine is connected to the sheep horn, and the ball head of the hand pull rod is connected to the parallel rod.

Generally, there are two, but the so-called "ball joint" is just a connection form of movable joint. As long as there is relative motion and it is necessary to connect, the ball joint connection mode is one of the possible design schemes, so there is no definite number for this. Of course, the most common one is the steering rod, followed by the suspension thrust rod.

Automobile ball joint: the outer ball joint refers to the hand pull rod ball joint, and the inner ball joint refers to the steering machine pull rod ball joint. The outer ball and the inner ball are not connected together. They have to work together. The ball head of the steering machine is connected to the sheep horn, and the ball head of the hand pull rod is connected to the parallel rod.

If the car's pull rod ball joint is broken, it will cause the steering wheel shaking, brake deviation, and direction failure. In serious cases, it may also cause the wheel to roll off instantly due to the ball joint falling off. The consequences are serious. It is recommended to replace it in time. The ball head of the pull rod is a pull rod with a ball head shell. The ball head of the steering spindle is placed in the ball head shell. The ball head is hinged with the edge of the shaft hole of the ball head shell through the ball head seat at the front end. The needle between the ball head seat and the steering spindle is embedded in the groove of the inner hole surface of the ball head seat, which has the characteristics of reducing the wear of the ball head and improving the tensile strength of the spindle. Next, Zhejiang Aslan Auto Parts Co., Ltd. will give you a detailed introduction about the knowledge of automobile rod ball joint. If you want to know more information, please continue to pay attention to the electric bond.

The symptom that pull rod ball head broke basically has a few kinds of circumstance below?

1. If the front wheel ball joint is broken, the following symptoms will appear

a. Bumpy road section, clattering;

b. The car is unstable, swinging left and right;

c. Brake deviation;

d. Direction failure.

3. The ball head is easy to break when it is subjected to impact load due to too large clearance. Repair as soon as possible to avoid danger.

3. The outer ball joint refers to the hand pull rod ball joint, and the inner ball joint refers to the steering machine pull rod ball joint. The outer ball and the inner ball are not connected together. They have to work together. The ball head of the steering machine is connected to the sheep horn, and the ball head of the hand pull rod is connected to the parallel rod.

4. If the ball joint of the steering tie rod is loose, it will lead to the steering deviation, tire eating and steering wheel shaking. If it is serious, it may also cause the ball joint to fall off and the wheel to fall off instantly. It is suggested that it should be replaced in time to avoid potential safety hazards
