What is daily car brakes?

1

Different types and material

When it comes to vehicle braking systems, one of its key components is the brake disc, currently we brake more common are the “drum brake” and “disc brakes” two types, which are also sometimes called disc brake disc brake, it is sub-normal disc brake ventilated disc brakes and two kinds. In addition, like some of the luxury sports car brand or optional equipment will be more advanced “ceramic brakes”, of course, also belong to the category “disc brake”.

Drum Brakes principle

For drum brakes by the brake link plate, brake wheel cylinder, brake shoes, etc., a spring, nail tip, brake drum formed. It is the use of the hydraulic device to push it inside the brake pad brake drum, brake pad and the inner surface of the wheel with the rotational friction of the brake drum, the brake effect generated.

drum brakes in the automotive above has been nearly a century of history, but because of its reliability, and a powerful braking force, so that the drum brakes today still configured (multi-use on many models in the rear ).

Drum brake member has a shape similar tambourine iron, known brake drum, which is fixed and the tire is rotated at the same speed. The inner surface of the drum brake of the drum brake is the braking position of the braking torque generating means. In the case of obtaining the same braking torque, the diameter of the brake drum brake drum brake device may be smaller than the disc brakes of many. So large vehicle truck used to obtain a powerful braking force, the device can only drum brakes in the limited space of the rim.

Briefly, a drumBrake is the use of the stationary brake pad drum brake, a friction brake drum to rotate with the wheel, a frictional force to brake the wheel rotational speed reduction.

When the brake pedal, the piston forward to push the brake oil in the brake master cylinder will force the foot and to generate a pressure in the oil passage. Pressure is transmitted via the brake fluid to the wheel brake cylinder of each piston, the piston brake wheel cylinder brake pad and then push outwards, the inner surface of the brake pads and the brake drum friction and generate sufficient friction to reduce the rotational speed of the wheel, in order to achieve the purpose of the brakes.

disc brake principle

disc brakes and disc brakes are connected by a circle and the wheel brake caliper edge components. When braking, the high pressure brake fluid to promote the clamping brake disc brake pad so as to produce a braking effect. Works disc brakes can be used to describe a dish, you pinch a rotating plate with thumb and forefinger, dishes will stop rotating.

Sometimes called disc brakes of disc brake, which brake disc and sub-normal two kinds ventilated disc brake. Ventilated disc brake plurality of circular vent holes are drilled in the disk, or the end surface of the disc or pre-cut out of the ventilation slots rectangular vents. Ventilated disc brakes use romantic effect, the cooling effect is better than ordinary disc brakes.

The cold air cooling of the wheel brakes by

[123 ] disc brake (disk brake) mode of action:

as the name implies, a stationary disc brake brake disc, with the rotation of the tire sandwiching the brake disc to generate a frictional force, so that brake wheel rotation speed reduction.

Disc brake discs

When the brake pedalWhen the piston is pushed in the brake master cylinder, the brake pressure is established in the oil. Brake fluid pressure is transmitted via the brake wheel cylinder to the brake caliper pistons, brake wheel cylinder after the piston under pressure moves outward and pushes the brake pads to clamp the brake disc, brake pads and the brake disc so that the friction to reduce wheel speed, so the car slow down or stop.

against the friction disc brakes and brake pads for braking the brake disc

Since the performance of the vehicle traveling fast rising, high speed to increase the vehicle driving stability when braking, disc brakes have become the mainstream in the brake system. Since the disc brake brake disc exposed to air, so that the disc brake has excellent heat dissipation properties, made when the vehicle brakes or multiple brakes at high speed in a short time, the performance of braking is less likely to decline, so that the vehicle can be obtained better braking effect, to enhance the safety of the vehicle.

Many vehicles use disc brake system with the ABS and VSC, TCS with other systems

and because of the rapid reaction of the disc brake, the ability to do high frequency braking action, so many car models with disc brake system with ABS and VSC, TCS with other systems, such systems need to meet the demand for rapid action to do.
