The utility model discloses a beneficial effect is: this scheme adopts the cylinder to replace the hydraulic system in traditional stopper, only need can realize the braking to letting in gas in the cylinder when applying the brake, does not consequently have the sealed problem of leaking with the brake fluid of traditional stopper, so the simple structure of the stopper of this scheme and reliability are high.

Description

Floating caliper type disc stopper

Technical field

The utility model relates to disc brake, is specially a kind of floating caliper type disc stopper.

Background technology

Caliper disc stopper is the one of disc brake. Its spinner member is with the metal disk of end face work, it is called retarding disc, retaining element is the little frictionshoe of working area and the brake pad of its metal backing composition, these brake pad and actuate device and be all contained in the clamp-shaped support of retarding disc both sides, being generically and collectively referred to as caliper, retarding disc and caliper together constitute caliper disc stopper.

Caliper disc stopper can be divided into by the structure pattern of caliper determines caliper disc and floating caliper type disc two kinds, traditional floating caliper type disc stopper is when braking, it is promote piston by high pressure braking fluid, piston promotes brake pad and presses and realize braking effect on the disc brake rotor, the mode of this kind of hydraulic braking needs to lead to the liquid into a large amount of, therefore in use need to design independent sealed structure, if what sealed structure did is not good simultaneously, the problem such as leakage is unloaded, thus the structure making stopper becomes complicated and working reliability reduces by what produce braking fluid.

Practical novel content

The utility model is intended to the floating caliper type disc stopper providing the simple and reliable property of a kind of structure high.

Floating caliper type disc stopper in this scheme, comprise caliper and retarding disc, caliper is provided with fixing brake pad, caliper the first groove and air inlet port have been offered with fixing brake pad phase opposite, air inlet port communicates with the first groove, and retarding disc, between fixing brake pad and the first groove, is provided with cylinder in the first groove, cylinder place is provided with the piston extending when cylinder is ventilated, and piston place has also been threaded movable brake pad.

Principle and the effect of this scheme be: during braking, ventilated in cylinder by air inlet port, when cylinder is ventilated, piston will extend, the movable brake pad being now connected with piston thread will to the motion of direction, retarding disc place until movable brake pad presses on the disc brake rotor, now retarding disc will to piston opposite effect power, under the reactive force of retarding disc, piston moves to the reverse direction at retarding disc place together with caliper entirety, until fixing brake pad also presses on the disc brake rotor, now fix brake pad and from both sides clamping retarding disc and produce the frictional force that prevention retarding disc moves with movable brake pad on a mating, and then realize the braking of wheel.

The useful effect of this scheme is: this scheme adopts cylinder to replace the hydraulic efficiency system in traditional braking device, only need when braking to lead in cylinder and can realize braking into gas, therefore there is not the sealing of traditional braking device and the problem of braking fluid leakage, therefore the structure of the stopper of this scheme simple and reliable property height.

Further, also comprise the bolt connecting caliper and cylinder, cylinder is provided with threaded hole, having offered the 2nd groove and bar hole on caliper, the 2nd groove and bar hole communicate, and bolt is through the 2nd groove, bar hole and threaded hole, cylinder can be positioned by bolt on the one hand, on the other hand when movable brake pad has abrasion, by the position of bar hole adjusting cylinders, and then the braking gap between guarantee activity brake pad and retarding disc.

Further, caliper is also offered the radiating ribs increasing heat radiation area, owing to stopper is the braking realized by the frictional force between brake pad and retarding disc, therefore stopper will produce a large amount of heats in braking process, by offering radiating ribs on caliper, the heat radiation area of caliper can be increased, and then the heat produced in braking process can be taken away timely and effectively, ensure that stopper works all the time in suitable temperature.

Further, in order to provide guiding to the motion of caliper, also comprising caliper support and guiding pin, screw offered by caliper support, caliper has been offered through hole, guiding pin is through described through hole and described screw.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model embodiment.

Embodiment

Below by embodiment, the utility model is described in further detail:

Reference numeral in Figure of description comprises: caliper 1, retarding disc 2, caliper support 3, guiding pin 4, air inlet port 5, the 2nd groove 6, cylinder 7, movable brake pad 8, fixing brake pad 9, braking pad 10.

Embodiment is substantially as shown in Figure 1: floating caliper type disc stopper, comprise caliper 1, the right-hand member of caliper 1 has offered air inlet port 5, it is provided with the first groove in the left side of air inlet port 5, first groove communicates with air inlet port 5, bar hole has been offered on the top being positioned at the first groove on caliper 1, bar hole communicates with the first groove, the 2nd groove 6 has been offered on the top of bar hole, 2nd groove 6 communicates with bar hole, caliper 1 is positioned at the part on the left of the 2nd groove 6 and has offered radiating ribs, radiating ribs is the taper structure that width gradually changes, wherein the width of radiating ribs and caliper 1 joint is bigger, all it is rounded down in radiating ribs and caliper 1 joint, it is circular sliding slopes at the top of single radiating ribs, this radiating ribs can increase the heat radiation area of caliper 1.

It is provided with cylinder 7 in the first groove of caliper 1, cylinder 7 has offered threaded hole, this threaded hole coordinates with the 2nd groove 6 on caliper 1 and bar hole and is bolted, by bolt, the different positions of bar hole is connected with threaded hole, can be used for the position of adjusting cylinders 7, piston also it is provided with in the left side of cylinder 7, when cylinder 7 is when ventilating, piston is extending, be threaded movable brake pad 8 in the left side of piston, when piston extends, the direction axial motion that movable brake pad 8 can extend with piston, and then carry out coordinating realization braking effect with retarding disc 2.

Face relative with movable brake pad 8 on caliper 1 is provided with fixing brake pad 9, braking pad 10 also it is provided with between fixing brake pad 9 and caliper 1, braking pad 10 can reduce impact between the two with retarding disc 2 when fixing brake pad 9 coordinates, and makes cooperation between the two more steady.

Being retarding disc 2 between movable brake pad 8 and fixing brake pad 9, when braking, movable brake pad 8 and fixing brake pad 9 clamp retarding disc 2 from both sides, thus make retarding disc 2 realize fast braking under the effect of both frictional force.

Lower position at caliper 1 has offered a through hole, it is provided with caliper support 3 in the left side of caliper 1 through hole, caliper support 3 is connected with outside vehicle frame, screw offered by caliper support 3, the thread segment of guiding pin 4 coordinates with the screw on caliper support 3, the through hole of the smooth section of guiding pin 4 on caliper 1, when caliper 1 moves left and right, caliper 1 is provided certain guide effect by guiding pin 4.

Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this. Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, it is also possible to make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability that the utility model is implemented.
