What are the advantages and disadvantages of the size of the car hub?

1. The advantages and disadvantages of the hub size of the car are as follows: large wheelVehicles with hubs will look very grand, and the vehicles are full of sport, especially some cars with large hubs, which look more cool than cars with small hubs.

2. Disadvantages of wheel hub size: Changing the tire diameter is actually allowed within a certain range. Some manufacturers will also provide different specifications of tire rims for car owners to choose from. This situation has little impact on the car, and your own modification may not be so thoughtful.

3. It is relatively durable. You can find the wheels and tires of this type of car, which can run on any road surface, especially on mountain roads, which is very durable. Strong anti-collision. It doesn't matter even if it's a nail. You can continue to drive. The disadvantage is that the grip of car tires is not as good as that of large wheels and thin tires.

4, inch hub and 2The difference between 0-inch hubs. There are many sizes of car hubs. The different sizes selected will bring a different car experience. So what is the difference between an 18-inch hub and a 20-inch hub? Cost: The manufacturing cost of 20-inch hubs will be a little higher than that of 18-inch hubs.

What is preventing wheels from holding dead?Meaning

AntilockBrakeSystem (ABS) is a rubber airbag safety device installed in the brake valve.

In fact, preventing the wheel from holding dead is a safety system on the car, which is what we usually call the ABS system. It can prevent the car from holding dead when the car brakes or gets out of control, so as to improve the safe driving of the car.

Anti-lock braking means to avoid the complete tightening of the wheels, resulting in a loss of control of the direction. If it is a sudden brake, you will hear a rattling sound from the bottom of the car at this time, which means that abs anti-locking is working.

Anti-lock-death is to prevent the car from braking once and use intermittent braking.Holding the dead means that the car brakes once during the braking process, and the tire no longer rotates. It is easy to cause cars to lose control and cause traffic accidents and other hazards.

Possible faults and hidden dangers of wheel abnormal noise

1. Wheel abnormal noise hides 6 types of fatal faults. The tire is stuck in nails or gravel. The sound is that the tire turns around and sounds, as if there is something" Banging on the ground, the pace accelerated as the speed of the car increased.

2. Unempy tread. This abnormal sound gives people the feeling that the tire seems to be crushing something all the time, making sounds similar to burping, burping, and is often accompanied by the shaking of the steering wheel, sometimes left and sometimes right. If these situations occur, it is recommended to replace the tires (or rims) in time and never continue to drive.

3. Fault 1: Rhythmic buzzing sound is emitted when driving at low speed, and the abnormal sound is weakened when driving at high speed. Cause of failure: The positioning of the four wheels of the vehicle is inaccurate, the tire wears a lot in long-distance driving, and the tires form partial wear and make abnormal noises.

4. There is a strange sound in the tire. The common fault points are: it may be that there is a stone stuck in the tire pattern, and there will be a "da-da-da" abnormal sound, and this abnormal sound will change the frequency with the change of speed of the car. The speed of the car is fast, the frequency is fast. The speed of the car is slow, the frequency is slow.

When the wheels of the car are moving, there are several modes of movement at the same time. Can you list them?

The car is driving on a straight highway. At this time, the movement of the car is translation, and the movement of the wheels is rotation.Rolling, swaying left and right, moving back and forth, so the suspension controls the various movements of the wheels, so there are so many connecting rods.

The movement modes of cars include: linear motion, curved motion, uniform motion, acceleration movement and deceleration movement.

When the car is running, the movement of the wheels and the body is as follows: when the car is running, the wheel rotates with the wheel axle as the center, which is a rotating motion; the body moves from back to front on the ground, which is a translation movement.

In the middle school stage, mechanical motion is divided into two modes: flat motion and rotation. Flat motion: In the process of motion, the connection of any two points on it remains unchanged at each moment.

At the same time, when braking, the center of gravity of the car will move forward, which can help the vehicle achieve better braking effect.
