Why don't cars design a rotating way to turn more flexibly?

In theory, cars can be designed to rotate.In fact, this is an application of rear-wheel steering technology. For example, this Jeep concept car has four wheels that can turn in different directions, not to mention turning. It is easy to turn in place in the same place.

Because of the main power of the front wheel, the driving car is not very good at drifting, just like people pulling things, wherever people go and things go. There are universal knots on the vehicle, and no matter how you turn, it will not have any impact.

The in-situ advantages of this direction are: flexibility and maneuverability, small track loss, and high comfort of the fuel tank. However, the disadvantage is that the mechanical design is too complicated, and there is a great loss without combat effectiveness.

What's wrong with the car hitting the steering wheel in place

1. The car does not move in place and the steering wheel clicking. The important thing is due to the damage of the car's steering machine, the friction of the shock absorber plane bearing, flat Loosening of the balance, friction of the airbag of the steering wheel and other effects.

2. [Pacific Automobile Network] The key to the steering wheel clicking in place is due to the damage to the steering machine of the car, the friction of the shock absorber plane bearing, the looseness of the balance rod, the friction of the steering wheel airbag, etc.

3. The sound of the direction column dustproof cover. Whether you are in place or driving, as long as you hit the steering wheel, you will hear the sound coming from under the steering wheel. You need to check the direction column dustproof cover. Once the direction column dustproof cover lacks lubrication, it will produce the sound of dry friction. You just need to apply some butter in the dustproof cover. It will disappear.

Wouldn't it be more flexible if the turning mode of the car was changed to rotation?

In addition, the current turning method is enough to meet the needs of the car, so all the wheels of the super-large flatbed car without dozens of axles can be turned in place. That turning is more flexible. Is it necessary as an ordinary vehicle?

When the steering wheel is turned, the steering wheel of the car rotates.That is, it rotates when the steering wheel is hit, and when the steering wheel is not played, it is a translation. During driving, when you need to turn the steering wheel, control the rotation of the steering wheel according to the speed of the vehicle. When changing lanes to the right, turn the steering wheel to the right. Pay attention to the speed when turning the steering wheel.

One: Insufficient steering is manifested in the fact that the actual steering angle of the vehicle when turning is smaller than the rotation angle of the front wheel. The forward wheel moves outward, or "drifting" may be easy to understand. Now the actual turning angle when the vehicle turns is greater than the rotation angle of the front wheel, that is, the rear wheel slides outward.

The big word is that with this configuration, the direction is obviously much easier and it is a very awesome configuration. High-speed steering will be easy to have accidents, the bottom speed steering will become smaller, the cornering will be more accurate, and the parking will be more convenient~.

In general cars, in order to controlThe steering wheel allows the tire steering of the front wheel to perform the turning function, but the four-wheel steering is a system that the tires of the rear wheel can also be turned.

Belongs to the second higher-order of the two ways to turn around the tank. In addition, vehicles equipped with the "tank turning" function can also achieve 4-wheel lateral rotation, diagonal movement and other difficult actions that seem impossible to complete on traditional vehicles.

Is the movement of the steering wheel of the car moving or rotating

The movement of the steering wheel of the car is both translation and rotating. When the car is driving straight, the steering wheel of the car moves. When you turn the steering wheel, the steering wheel of the car rotates. It can also be said that it rotates when the steering wheel is hit, and it moves when the steering wheel is not hit. If the steering wheel is not correct, it can be divided into the following two reasons: the first is a simple steering wheel tilt.

The movement of the steering wheel of the car has both translation and rotation. When the car is driving straight, the steering wheel of the car is moved. When you turn the steering wheel, the steering wheel of the car rotates. That is, it rotates when the steering wheel is hit, and when the steering wheel is not played, it is a translation. During driving, when you need to turn the steering wheel, control the rotation of the steering wheel according to the speed of the vehicle.

The movement of the steering wheel of a car is divided into two types: translation and rotation. When the car runs in a straight line, the steering wheel will move; and when the steering wheel turns, it will rotate. In addition, there may be two reasons why the steering wheel is not straight when driving in a straight line.

Can a spinning car be regarded as a mass point?

1. What can be regarded as a mass point is: study the speed of the movement of cars on the highway;Study the time it takes for athletes to complete the course, etc. What cannot be regarded as a point is: studying the movement of the wheels of a running car; studying the posture of athletes when running, etc.

2. When the earth moves around the sun, it can be regarded as a point. When the sun moves around the Milky Way, it can be regarded as a point, but when studying the rotation of the earth, the earth cannot be regarded as a point. When the train is from Shenzhen to Shanghai, it can be seen as a mass point, but it cannot be seen as a mass point when the train crosses the bridge.

3. Then this object can be regarded as a mass point when it is studied. When the wheels of the car rotate, for example, when the car moves forward, some parts (the upper half of the wheels) move forward, and some parts (the lower half of the wheels) move backwards. This is easy to see if you look closely at the rotation of the disc. Therefore, the wheel cannot be regarded as a quality point at this time.

4. A point is a point with mass but no volume and shape. Usually, if the size of the object is relatively small or has little impact on the object of study, the object can be regarded as a mass point.

5. When the object itself does not have much impact on the problem studied, it can be regarded as a quality point. For example, the time it takes for a car to cross the bridge. You can not only consider the length of the bridge, but also the length of the car.
