Tell me about that amazing car.

Four cold knowledge about cars, each configuration is amazing.

Four "cold knowledge" about cars, each configuration is amazing, just know two.

There are many cleverly designed key devices on the car. Without these devices, cars will run or run into obstacles. Let me talk about these configurations first. Four "cold knowledge" about cars is amazing. It's good to know two.

1, turn to the ball cage. In many people's minds, there may have been such questions. In fact, in the process of power transmission, the steering ball cage is the most critical device, which can realize power transmission at a certain angle, so as to achieve the effect that the front wheels can turn and have power output.

2. differences. This is also a very clever design. Differential plays an important role in whether a car can run on the road in a better state. As many people know, the wheels are not related to the transmission shaft, they are independent, that is, there is no interference with each other. But for the wheels associated with the drive, without the help of the differential, the two wheels will interfere with each other, resulting in the instability of the car.

For example, if the car is driving on a bad road, if the two wheels exert force at the same time with the same force, the car may lose its balance and fail to achieve the corresponding effect required by the driver. With the help of the differential, the wheels that need high power support can be more powerful. In reality, the role of differential in off-road vehicles is more obvious. When a car is stuck in a rough pit and wants to get out, it often doesn't need two wheels of the car to exert force at the same time, only one wheel is needed to exert force. At this time, the differential can play such a role, let the one-sided wheel exert force, and then help the car get out of danger.

3. Universal joint. This equipment is also very important. It is also a key component to change the direction of power output. This part is usually used for transmission shaft and steering column. With it, the freedom of automobile in spatial layout is higher.

4. Shock absorber. Everyone knows the importance of suspension, especially when passing through some bad roads. If your car has a good suspension system, you will feel more comfortable in it. Here we need to know the components of automobile shock absorption, including springs and shock absorbers for shock absorption.

We assume that the shock-absorbing spring will be compressed by the impact force when the car passes through the buffer belt. Once the buffer belt passes, the spring will stretch to release the elasticity, and then the car will bounce, which is a bad driving experience. In order to reduce the upward elastic force, a shock absorber was invented. Because of this shock absorber, it can absorb the elasticity of the spring, and then make the people in the car sit more comfortable.
