Abstract
The invention discloses a braking noise preventing device of a brake. The braking noise preventing device comprises calipers. A piston, a piston cap, an inner friction plate, a brake disc and an outer friction plate are fixedly mounted in the calipers in sequence. The piston cap comprises a body, a clamping foot and an elastic piece. The clamping foot is connected to the edge of the body which is provided with a through hole, one end of the elastic piece is connected to the edge of one side of the through hole, and the other end of the elastic piece is a free end. According to the braking noise preventing device, the piston cap is added, so that a force transfer path between the piston and the friction plates is changed, damping is increased, vibrating noise of a specific frequency is restrained, and the comfort of a whole car is improved.
Description
Technical field
The present invention relates to break technical field, particularly relate to the anti-brake noise device of a kind of break.
Background technique
After current clamp braking is stressed, brake disc, clamp, friction plate intercouple, and likely can produce brake noise, cause the complaint of user.In order to improve the comfort of user, it is necessary for eliminating this brake noise.
Summary of the invention
For the deficiency that prior art exists, object of the present invention just there are provided the anti-brake noise device of a kind of break, by adding piston cap, change the power bang path between piston and friction plate, increase damping, the vibrating noise of containment characteristic frequency, adds the travelling comfort of car load.
To achieve these goals, the technical solution used in the present invention is such: the anti-brake noise device of a kind of break, comprise clamp, piston, piston cap, inner attrition piece, brake disc and outside friction disc is installed with successively in described clamp, described piston cap comprises body, engaging pin, shell fragment, and described engaging pin is connected to the edge of body; Described body has through hole, and one end of described shell fragment is connected to the side edge of through hole, the other end is free end.
As a kind of preferred version, described engaging pin is that elastic card fits.
As a kind of preferred version, described engaging pin has 3, and 3 engaging pin are uniformly distributed on body.
As a kind of preferred version, described through hole has 3, and 3 through holes are evenly opened on body.
As a kind of preferred version, described through hole with engage pin and be crisscross arranged on body.
As a kind of preferred version, the quantity of described shell fragment is identical with through hole.
Compared with prior art, beneficial effect of the present invention: anti-brake noise device of the present invention, by adding piston cap, changes the power bang path between piston and friction plate, increases damping, and the vibrating noise of containment characteristic frequency, adds the travelling comfort of car load.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is structural blast figure of the present invention;
Fig. 3 is the structural representation of piston cap in the present invention.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.Following examples only for technological scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
Embodiment:
As shown in Figure 1 and Figure 2, the anti-brake noise device of a kind of break, comprise clamp 1, piston 2, piston cap 3, inner attrition piece 4, brake disc 5 and outside friction disc 6 is installed with successively in described clamp 1, as shown in Figure 3, described piston cap 3 comprises body 31, engaging pin 32, shell fragment 33, and described engaging pin 32 is connected to the edge of body 31; Wherein engage pin 32 to fit for elastic card, engaging pin 32 has 3, and 3 engaging pin 32 are uniformly distributed on body 31; Described body 31 has through hole 34, and described through hole 34 has 3, and 3 through holes 34 are evenly opened on body 31, described through hole 34 with engage pin 32 and be crisscross arranged on body 31; One end of described shell fragment 33 is connected to the side edge of through hole 34, the other end is free end, and the quantity of shell fragment 33 is identical with through hole 34.During braking, piston 2 pushes down inner attrition piece 4, make inner attrition piece 4, outside friction disc 6 and brake disc 5 rub, reduce the speed of a motor vehicle, due to pressure distribution, friction factor, temperature, humidity, the impacts such as damping, the natural frequency that braking system is adjacent may be coupled, resonate, produce brake noise, invention increases piston cap 3, change the pressure distribution that piston 2 presses inner attrition piece 4, change power bang path, increase damping, reduce the probability of the adjacent natural frequency coupling of braking system, thus reduce noise probability of happening, improve the travelling comfort of car load.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
