CN203051567U - Brake disc for automobile - Google Patents

Abstract

The utility model relates to a brake disc for an automobile. The brake disc comprises a disc body (1), and is characterized in that the two side surfaces of the disc body (1) are rough surfaces (2) respectively, and each rough surface (2) has the structure that regular convex and concave stripes are arranged on the surface of the disc body (1); and each rough surface (2) also has the structure that fan-shaped convex and concave stripes are arranged on the surface of the disc body (1). Compared with the prior art, the two side surfaces of the disc body are set into the rough surfaces, so that the coefficient of friction of the disc body is effectively increased, and thus the sensitivity of braking is improved, and meanwhile, the service life of the brake disc is also prolonged. Therefore, the brake disc provided by the utility model is a very practical product, and is worthy of popularization and application.

Description

Automobile brake disc

Technical field

The utility model relates to a kind of braking automobile technical field, especially refers to a kind of automobile brake disc.

Background technique

Existing a kind of patent No. discloses a kind of structure for the Chinese utility model patent that the 200920219763.X name is called " automobile brake disc ", its structure comprises front friction disk and back side friction disk, the two connecting tendon by some uniform settings radially centered by the center of circle of front friction disk and back side friction disk is welded as a whole, form heat dissipation channel between the adjacent connecting tendon, be respectively equipped with some heat radiation through holes that communicate with heat dissipation channel on the front and back friction disk, also be provided with some drain groove that centered by the center of circle of friction disk, distribute radially on the outer surface of front and back friction disk, the direction of rotation of heat dissipation channel curved and its protrusion direction and brake disc, drain groove is curved and its protrusion direction is identical with the sense of rotation of brake disc.This model utility, because heat dissipation channel is curved and the direction of rotation of its protrusion direction and brake disc, the drain groove on the outer surface of friction disk is curved, so radiating effect that can provide, brake lining water drainage skid, anti-shake makes brake more stable, and stopping distance obviously shortens.But the shortcoming of this model utility is: friction disk is provided with the heat radiation through hole, makes water enter disk body inside easily, causes disk body inside to be got rusty and last dust, thereby influences the working life of friction disk, so its structure awaits to improve.

The model utility content

Technical problem to be solved in the utility model is to provide a kind of simple in structure and can effectively prevent the automobile brake disc that skids at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technological scheme that adopts: this automobile brake disc, comprise disk body, and it is characterized in that: the bi-side of described disk body are respectively roughened surface.

As improvement, the structure of described roughened surface can be preferably: in described disc surfaces well-regulated concave and convex stripe is set.

As improvement, the structure of described roughened surface may be selected to be: the concave and convex stripe that is provided with fan shape in described disc surfaces.

Compared with prior art, the utility model is set to roughened surface by the disk body bi-side, increased the friction factor of disk body effectively, thereby improved the sensitivity of brake, also prolong simultaneously the working life of automobile brake disc, therefore the utility model is a kind of very practical product, is worthy of popularization.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

To shown in Figure 6, the automobile brake disc of present embodiment comprises disk body 1 as Fig. 1, and the bi-side of described disk body 1 are respectively roughened surface 2; The structure choice of described roughened surface 2 is: on described disk body 1 surface well-regulated concave and convex stripe is set.Certainly, the structure of described roughened surface 2 also can be chosen as: the concave and convex stripe that is provided with fan shape on described disk body 1 surface.The utility model is provided with roughened surface 2 by disk body 1 bi-side, thereby has increased disk body 1 bi-side friction factor effectively, has improved the sensitivity of brake then.

Claims (3)

1. an automobile brake disc comprises disk body (1), it is characterized in that: the bi-side of described disk body (1) are respectively roughened surface (2).

2. automobile brake disc according to claim 1, it is characterized in that: the structure of described roughened surface (2) is: on described disk body (1) surface well-regulated concave and convex stripe is set.

3. automobile brake disc according to claim 1, it is characterized in that: the structure of described roughened surface (2) is: the concave and convex stripe that is provided with fan shape on described disk body (1) surface.
