CN203146670U - Chamfered brake pad - Google Patents

Abstract

The utility model discloses a chamfered brake pad, which comprises a substrate and a friction sheet arranged on one side of the substrate, wherein the other side of the substrate is provided with an installing block; the two ends of the friction sheet are provided with chamfers; the angles of the chamfers are 25 degrees. The chamfers of the friction sheet are large, the slopes are relative gradual, and the transition process of contact between the brake pad and a brake disk in a braking process is prolonged due to the gradual angles, so that braking is more gradual, the shake of the brake disk is effectively reduced in the braking process, and the comfort of a vehicle is improved greatly.

Description

A kind of chamfering type brake block

Technical field

The utility model relates to a kind of auto parts machinery, particularly a kind of chamfering type brake block.

Background technique

NVH refers to Noise (noise), Vibration (vibration) and Harshness (sound vibration roughness), because above three occurs and interwoveness simultaneously, therefore often they is put together and studies.NVH is a global question weighing the automobile making quality, and it gives the impression of user vehicle is the most direct and the most surperficial, and it is one of problem of international automobile each big car load manufacturing enterprise of industry and component enterprises pay attention.Have statistics to show, it is relevant with the NVH problem of vehicle that car load has 1/3 failure problems approximately, and there is nearly 20% research and development cost consumption in each major company on the NVH problem that solves vehicle.

Brake block is as the breaking piece of most critical in the automobile brake system, it has an immense impact on to the NVH performance of automobile equally with noise and vibration that the contact friction of brake disc etc. produces in braking process, therefore need chamfering be set at brake block, so that brake block contacts a transient process that touches comprehensive engagement from part with brake disc, and the brake block of prior art, with reference to figure 1 and 2, because chamfering 12 angles of its friction plate 11 are 45 degree, chamfering 12 angles are less, the gradient is bigger, therefore transient process is comparatively rapid, still can produce bigger vibration and noise at braking process, therefore, how further improve braking ability, promote normal N VH performance, become the emphasis problem of brake block research and development.

The model utility content

For solving the problems of the technologies described above, the utility model provides a kind of chamfering type brake block, the NVH performance when braking to improve brake block.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of chamfering type brake block, the friction plate that comprises base material and be installed in described base material one side, described base material opposite side is provided with mounting blocks, and the two ends of described friction plate are provided with chamfering, and the angle of described chamfering is 25 degree.

Pass through technique scheme, a kind of chamfering type brake block that the utility model provides, the chamfering of improvement back friction plate is big and the gradient is mild relatively, milder angle makes the transient process that brake block contacts with brake disc in the braking process prolong, thereby make braking become milder, effectively alleviated the shake of brake disc in the braking process, made the travelling comfort of vehicle obtain bigger improvement.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below.

Fig. 1 is the plan structure schematic representation of a kind of brake block of prior art;

Fig. 2 is the side-looking structural representation of Fig. 1;

Fig. 3 is the plan structure schematic representation of the disclosed a kind of chamfering type brake block of embodiment;

Fig. 4 is the side-looking structural representation of Fig. 3.

Embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described.

With reference to figure 3 and 4, the chamfering type brake block that the utility model provides, the friction plate 11 that comprises base material 21 and be installed in base material 21 1 sides, base material 21 opposite sides are provided with mounting blocks, and the two ends of friction plate 11 are provided with chamfering 12, and the angle of chamfering 12 is 25 degree.

A kind of chamfering type brake block that the utility model provides, the chamfering 12 of improvement back friction plate 11 is big and the gradient is mild relatively, milder angle makes the transient process that brake block contacts with brake disc in the braking process prolong, thereby make braking become milder, effectively alleviated the shake of brake disc in the braking process, made the travelling comfort of vehicle obtain bigger improvement.

Multiple modification to above-described embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.

Claims (1)

1. chamfering type brake block, the friction plate that comprises base material and be installed in described base material one side, described base material opposite side is provided with mounting blocks, it is characterized in that, and the two ends of described friction plate are provided with chamfering, and the angle of described chamfering is 25 degree.
