1. It's not calculated. Even if calculated, it can not be used as the design basis

2. The self weight multiplied by the maximum moving speed, the maximum static friction force and the reaction force are about the same
3. The ground braking force is the axle load multiplied by the adhesion coefficient. The calculation of brake force is much more troublesome
4. The distance from the brake surface to the axle center of the brake disc multiplied by the braking friction force
because the braking effect provided by the brake is ultimately in the form of torque, it is the braking torque (the size is related to the pressure)

5. Introction to automobile braking force
in the automobile instry, we often hear such a word, automobile braking force, but people don't know much about automobile braking force. Let's analyze what is automobile braking force
introction of automobile braking force 1: explanation
introction of automobile braking force 1: explanation
automobile braking is braking, and braking force is the maximum rolling friction that can be achieved, because when rolling changes to sliding, the friction will drop suddenly, that is, the maximum rolling friction is greater than sliding friction, which is why automobile has anti lock system
braking performance is one of the main performances of automobile, which is related to driving safety. The most basic indexes to evaluate the braking performance of a car are the braking acceleration, braking distance, braking time and the stability of braking direction

the braking force of a car depends on the friction of the brake, but the braking force that can make the car brake slow down, It is also restricted by the ground adhesion coefficient
introction of automobile braking force 3: calculation formula
introction of automobile braking force 3: calculation formula
when the braking force generated by the brake increases to a certain value, the automobile tire will slip on the ground. Its slip ratio δ＝ ( V t -V a )/V t × 100% where: δ-- Slip ratio; Vt -- theoretical speed of vehicle; V a -- the actual speed of the car
according to the test, when the wheel slip rate is high, the wheel slip rate is low δ＝ Therefore, in order to obtain the best braking effect, the slip ratio must be controlled in the range of 15% - 20%
the ratio of total braking force to vehicle weight is more than 60% under no load and more than 50% under full load; The ratio of the braking force of the main bearing shaft to the axle load is more than 60% under no load and more than 50% under full load. Generally, the braking force of the car is about 3000n
it turns out that automobile braking force plays such an important role, so when you buy a car, you must pay attention to whether the function of automobile braking force is excessive
