Description
[technical field]
The utility model relates to the automobile brake field, relates in particular to automobile back wheel service brake and parking braking.
[background technique]
Light-duty vehicle mostly adopts hydraulic braking, and hydraulic pressure will use pipeline.Double-circuit braking system just is meant independently hydraulic braking pipe-line system of two difference in the system, play insurance.General f-w-d car adopts intersection diagonal form more, the ante-chamber of brake master cylinder communicates with the braking line of off-front wheel, left rear wheel, back cavity communicates with the braking line of the near front wheel, off hind wheel, form " X " shape diagonal of an intersection, its benefit is when a braking system breaks down, another system still can carry out MIN braking, and is difficult for taking place the automobile deviation phenomenon.And the rear wheel drive car is bigger because of load, adopts independently braking model of front and back wheels difference more, and two cover braking overall pumps are promptly arranged, the front wheel brake of a cover control, another set of control trailing wheel braking.
Present break mainly contains disk type braker and drum brake.
Disk type braker is called disc brake again, is to get its shape and gain the name.It is by hydraulic control, and main parts size has brake disc, brake cylinder, brake calipers, oil pipe etc.The alloy steel for braking discs manufacturing also is fixed on the axletree, with wheel.Wheel cylinder is fixed on the base plate of break.Two friction plates on the brake calipers are contained in the both sides of brake disc respectively.The hydraulic pressure that the piston of wheel cylinder is transported by oil pipe promotes friction plate and presses to brake disc generation friction catch.This break rapid heat dissipation, in light weight, simple structure, easy to adjust.Particularly resistance to high temperature is good during high capacity, and braking effect is stable, and is not afraid of the muddy water invasion and attack.Also opened many apertures on the brake disc of some disk type braker, quickened ventilation and heat and improve retardation efficiency, such disk type braker is called the ventilated disc break again, because its manufacture cost is higher, generally only is used for the front-wheel of four-wheel disc type brake car.Certainly, disk type braker also has the defective of oneself.For example the manufacturing of break and braking line is had relatively high expectations, the losing quantity of friction plate is bigger, and cost is expensive, and because the area of friction plate is little, the working surface of friction is also less relatively, and the brake fluid pressure height that needs must have the vehicle of power assisting device to use.At present, most of Advanced Sedan Car adopt the four-wheel disk type braker.
Drum brake is the automotive brake of earliest form, and before disk type braker did not also occur, it had been widely used on all kinds of automobiles.But because structure problem, in nearly 30 years, it progressively makes way for disk type braker in the car field.But because cost is lower, it still uses in some economic class cars at present, is mainly used in less trailing wheel of brake load and parking braking.The car drum brake generally is used for trailing wheel.Drum brake also has a benefit except cost is relatively low, be convenient to exactly with Parking be that stopping brake is combined, every trailing wheel is the car of drum brake, its Parking Brake also is combined on the rear wheel brake.This is a mechanical system, and it separates with hydraulic braking system on the car fully: utilize hand lever or Parking pedal tension steel cable, handle the thick stick spare expansion brake shoe of drum brake, play the stopping brake effect, it is moving to make that automobile can not slip; Unclamp steel cable, return spring sets back brake shoe, and braking force disappears.
The general front wheel brake of present medium-to-high grade car adopts disk type braker, and trailing wheel braking employing dish drum is in conjunction with break, and parking braking is finished by the drum brake of braked-disc hub portion.The car front and rear wheel braking that also has is all adopted and is decided the jaw type disk type braker, but adorns the auxiliary braking pincers that a cover is used for parking braking in addition at trailing wheel.The structure of these breaks is all complicated, and installation difficulty is bigger, causes the probability of braking failure higher, and manufacture cost is also higher.
