Description
Technical field
The utility model relates to automobile hydraulic disk braking system, particularly relates to a kind of novel multi-disc disk type integrated arrestor.
Background technique
Hydraulic brake is widely used a kind of arrestment mechanism in automotive field, so far existing history for many years.Produce hydraulic drive brake calipers primarily of hydraulic component, make brake calipers and brake disc friction, produce braking.Alloy steel for braking discs manufacture is also fixed on wheel, with vehicle wheel rotation.
But the losing quantity of traditional disk brake friction wafer is larger, cost is expensive, and due to the area of friction plate little, the working surface of Relative friction is also less, according to braking moment formula: M=FR, wherein R is the Braking arm of force on the disc brake rotor, relevant with brake disc diameter, brake disc diameter can not be increased when tire limited space, increasing braking moment can only by increasing the hydraulic coupling of brake calipers, hydraulic coupling there will be friction working after increasing increase, causing the heat acted on the disc brake rotor effectively not cool causes brake disc metallicity to change, brake disc burns red by serious meeting, brake shoe burning is smoldered.Therefore can strengthen the loss of friction plate, reduce braking ability.
Summary of the invention
The utility model is for the problem of the easy loss of existing disk type braker, and according to existing vehicle tyre bulk, and the working principle of clutch devises a kind of novel multi-disc disk type integrated arrestor.
Design proposal of the present utility model is as follows: a kind of novel multi-disc disk type integrated arrestor, by being arranged on the brake disc that is close in housing and piston chamber is formed, described brake disc is connected with rotation shaft of wheel, one end axle that brake disc is adjacent with piston chamber is provided with friction plate integrated, described piston chamber is fixed in vehicle bridge, in it, piston is installed, piston with bottom piston chamber between be connected with spring supporting, the integrated contact of the front end of piston and the friction plate on brake disc is compressed, the end of piston contacts with hydraulic oil, piston chamber is provided with the filler opening be connected with hydraulic oil pipe system, be connected with the oil outlet of wheel cylinder, hydraulic oil is inputted in piston chamber, by hydraulic drive piston movement.
Described brake disc is fixedly connected with the integrated employing spline of friction plate.Brake disc and on brake disc external splines is set, arrange friction plate internal spline on friction plate is integrated, both are connected.
Be provided with seal ring between described piston and piston chamber, prevent fluid leakage in piston chamber.
It is integrated that the oil that oil pump comes enters piston chamber's promotion piston pressing friction sheet from oil circuit, the whole stepless action of pressure of oil is made to produce friction catch moment on friction plate each friction plate integrated, make that friction plate is integrated to stop operating with piston, because each friction plate internal spline and brake disc external splines pass through spline joint, brake disc also stops operating with friction plate is integrated, reaches braking effect.When brake petal unclamps, oil pressure reduces, and under the effect of recoil of spring power, it is integrated that piston departs from friction plate, and friction plate is integrated normally to travel with tire or wheel hub when losing braking moment with brake disc.
Compared to prior art, the utility model increases a little at brake assembly axial space, the braking moment n(n that the braking moment obtained in radial diameter and the constant situation of braking and drive force exceedes prior art is in theory the sheet number of the integrated friction plate of friction plate) doubly, cost does not increase substantially, in future automobile, purposes widely, and the automobile that particularly weight ratio is larger uses advantage more obvious.

Embodiment
Below in conjunction with specific embodiment and Figure of description, the utility model is described in further detail.Specific embodiment described herein only in order to explain the utility model, and is not used in restriction the utility model.
Embodiment: as shown in Figure 1, a kind of novel multi-disc disk type integrated arrestor, be provided with adjacent brake disc 1 and piston chamber 6 in housing, described brake disc 1 is connected with rotation shaft of wheel, and one end axle that brake disc 1 is adjacent with piston chamber 6 is provided with several friction plates integrated 2.As shown in Figure 2, brake disc 1 is arranged brake disc external splines 3, friction plate integrated 2 arranges friction plate internal spline 4, between brake disc 1 with each friction plate integrated 2, adopt spline fitted to be connected.Piston chamber 6 is fixed in vehicle bridge, is provided with piston 5 in it, with several spring 7 support and connection between piston 5 and piston chamber 6 bottom shell, the front end of piston 5 is contacted with the friction plate on brake disc 1 integrated 2 and compresses.Piston chamber 6 is provided with the filler opening 8 be connected with hydraulic oil path for automobile system, filler opening 8 connects with the oil outlet 17 of point pump assembly 9, imports hydraulic oil and enters piston chamber 6, moved by hydraulic control piston 5 in piston chamber 6.The gap of piston 5 and piston chamber 6 adopts seal ring 10 to carry out closed processes, prevents hydraulic oil from revealing.
The wheel cylinder of automobile brake hydraulic system, the oil outlet 17 of its oil pipe 11 is connected with the filler opening 8 of piston chamber 6, forms oil circuit, by hydraulic pilot piston 5.
During skidding, oil enters piston chamber 6 from hydraulic oil path for automobile system and promotes piston 5 and compress friction plate integrated 2 brake disc 1, the whole stepless action of pressure of oil, on each friction plate of friction plate integrated 2, thus produces friction catch moment, friction plate integrated 2 is stopped operating with piston 5.Also stop operating with the brake disc 1 of integrated 2 spline joints of friction plate thereupon, reach the function of braking.When brake petal unclamps, oil pressure reduces, and piston 5, under the effect of recoil of spring power, is separated with friction plate integrated 2, brakeless moment loading, and friction plate integrated 2 and brake disc 1 normally travel with tire or wheel hub.
In theory, the braking moment that this integrated arrestor produces, proportional with the friction plate number set by friction plate integrated 2.Therefore increase the friction plate number that brake disc connects, braking moment will become multiple to increase.Compared with existing disk type braker, same braking force can obtain the braking moment of several times, and braking effect is better.
Be the utility model preferred embodiment in sum, all changes made according to technical solutions of the utility model, all belong to protection domain of the present utility model when the function of producing does not exceed the scope of technical solutions of the utility model.
