Principle car brakes brake
Brake
works mainly from friction, car use brakes and brake disc (drum) and
tire friction with the ground, the vehicle kinetic energy is converted
into heat traveling friction after the car stopped. A
good efficiency of the brake system must be able to provide stable,
sufficient braking force can be controlled, and has good heat transfer
and hydraulic capacity to ensure that the driver from the brake pedal
applied force is transmitted to the master cylinder can be fully
effective and each cylinder, and avoid high fever caused by a hydraulic brake failure and decline. Brake
system on the car is divided into two major categories of disc and
drum, but in addition to cost advantages, the efficiency is far smaller
than drum brakes disc brakes, so the brake system discussed in this
paper will only disc brakes based. Start or doomed tragic and maintenance of your new car has a great relationship nondefective.
Friction
"Friction" refers to the relative motion of two objects moving resistance between the contact surfaces. Frictional force (F) is the size of the force and a positive pressure vertical plane suffered (N) is proportional to the product of friction and friction coefficient (C), expressed as a formula in physics:. F = (N for brake systems said :( means to make the coefficient of friction plate and brake disc, N is a piston brake calipers on to the film applied force (Pedal Force). the greater the friction generated by the friction coefficient is greater, but to the film the coefficient of friction between the disc because of heat generated by friction and after the change and that is the friction coefficient (C) is the change with temperature changes, each to the film because of different materials and have different The friction coefficient curve, so different to the film have different optimum operating temperature, and applicable operating temperature range, which is that you buy to make films need to know.
Brake force transfer
Piston brake calipers on to the film of the applied force is called: brake pedal force (Pedal Force). The driver stepped on the brake pedal force amplification effect pedal mechanism via a lever, the via vacuum power assist device (power boost) the principle of using vacuum pressure differential power amplification and then used to push the brake master cylinder. Utilization of liquid fluid pressure brake master cylinder emitted incompressible power transmission effect, delivered to each cylinder via the brake hose, and use "Pascal's principle" pressure amplification, push cylinder piston for urging the brake pads. "Pascal's principle" (Pascal's Law) refers to are the same for any position in one of the pressure in a closed container.
Pressure is obtained by dividing the biasing force area, in the case of equal pressure, we are able to take advantage of changing the applied force by the size of the area to achieve dynamic magnification ratio effect (P1 = F1 / A1 = F2 / A2 = P2) ??? Used in the brake system, the ratio of the master cylinder and the cylinder pressure is the master cylinder piston area of the piston and cylinder area ratio.
