Description
Technical Field
The invention relates to the technical field of automobile braking, in particular to a wheel braking force adjusting device and an automobile.

In the actual braking process of the automobile, sometimes the automobile is out of control and leaves the original driving direction due to braking deviation, and even the automobile is collided into the driving track of the opposite vehicle or slides down a hill; when the vehicle is emergently braked, once the braking deviation occurs, a driver is easy to scare and lose measures, so that the driving danger is greatly increased, and the braking deviation becomes one of important reasons for causing traffic accidents. The braking deviation of the automobile is usually caused by the large difference of the braking force of the wheels at the left side and the right side of the same axle.
At present, a front-back independent double-circuit braking system is adopted in an automobile, and because a left wheel and a right wheel share the same braking circuit, under an ideal condition, the braking force of the left wheel and the braking force of the right wheel of the automobile are completely consistent, so that the braking deviation can be avoided; however, in the actual processing of the brake system, due to factors of processing precision and errors, actual braking forces of the left wheel and the right wheel are different; because the left wheel and the right wheel share the same brake circuit, when the braking direction is unstable due to the fact that the braking force of the left wheel and the braking force of the right wheel are not uniform, the braking force of the left wheel or the braking force of the right wheel cannot be adjusted rapidly, only all parts in a brake system can be detected and checked, and the brake system is low in efficiency, time-consuming and labor-consuming; and because the braking force of the left wheel or the right wheel cannot be respectively adjusted, the correlation degree of the difference value of the braking force of the left wheel and the braking force of the right wheel and the stability of the braking direction cannot be verified. The braking direction stability refers to the ability of the automobile to keep running straight or according to a preset curve in the braking process without braking deviation.
In order to solve the problem that the actual braking forces of the left wheel and the right wheel are different due to factors of machining precision and errors, an Electronic Control Unit (ECU), a sensor and an Electronic Control circuit are added in a braking system of part of automobiles, so that the load condition, the braking air pressure and the ground adhesion force of the automobile during braking can be monitored in real time, and then the braking forces of the wheels are automatically adjusted through calculation processing of an ECU controller; however, the number of added parts is large, so that the structure of the whole braking system is complex, and the price of the added parts is high, so that the production cost is high.
In view of the above, it is desirable to design a wheel braking force adjusting device and an automobile to solve the above problems.
