We all know that a bicycle has two wheels and a car has four wheels. The bicycle brake must first brake the rear wheel, otherwise easy to overturn, then the car brake should brake which wheel? Is it four wheels together?
Which wheel is the brake on the car
When the car brakes, the four wheels brake at the same time. There is no difference in who is first and who is later, but there is a difference in the distribution of braking force before and after. If the brakes have a braking sequence, it is easy to lead to insufficient braking power and long braking distance, so the foot brake must brake all four wheels at the same time. But because the braking force distribution is different. In most cases, the handbrake only locks the rear wheel, regardless of the driving form, and most passenger car handbrakes only act on the rear wheel.
Are the brakes on the front or rear wheels of a car
When the car brakes or four brake calipers at the same time to brake the wheel is better, can make the vehicle to achieve safe braking effect, otherwise it will lead to lack of power. But the braking force of the front and rear brakes is different, because when the vehicle is driving forward, the inertia and center of gravity are in the front of the car, if the body is not 50:50 weight, the weight of the front and rear is usually greater than the rear of the car, the front and rear braking force needs more braking force.
Technically, the braking time of the four wheels is still different, but because the time is very short, around a few hundredths of a second, the naked eye is not able to react. Generally, the front wheel is the priority, and the rear wheel is the first brake, which is mainly a large truck and other large cars.
The braking force of the driving wheel is greater than that of the driven wheel, but it is true that both front and rear wheels brake. At present, disc brake is the main form of automobile, some models are front disc and rear drum brake system. The mass wheel of disc brake has good heat dissipation performance and is more advanced in technology.
Braking force distribution if the front and rear fixed uniform distribution, can not achieve the best effect of braking. So from the technical use of load sensing proportional valve dispensing power. In simple terms, with a load sensing proportional valve, you can change the proportion of front and rear wheel braking force according to the change of vehicle load, not a fixed uniform value after delivery.
What should I pay attention to when I brake
First we need to know the performance of the vehicle we are driving, how far the brake pedal travels and how hard it needs to be to stop the car.
While driving, we must concentrate on the road and driving conditions. In the case of emergency braking, you can reserve the braking distance for yourself and do not panic to avoid the accelerator becoming the brake.
Distance permitting, we adopt snub as far as possible, so can reduce much our vehicle brake pads, and the damage of the tire, but also pay attention to look at the rearview mirror, the rear vehicle, at this time if there is a car behind, and doesn't slow down, so you have to open the double flash, in the premise of safety, prepared to change lanes.
But in an emergency, it's important to keep a tight grip on the steering wheel and put the brakes on to minimize the impact of the vehicle and injuries to the occupants.
