Abstract

The utility model discloses a brake disc for a heavy duty vehicle, which comprises a disc body, and is characterized in that one end of the disc body, which is connected with a brake block is equipped with two working surfaces, a plurality of heat dissipation holes are arranged between the two working surfaces, the heat dissipation holes are evenly distributed on the circumference of the working surface, and one end of the disc body, which is connected with a hub is equipped with an outward projecting flange surface with a bolt hole. The brake disc for a heavy duty vehicle is equipped with two working surfaces, thereby guaranteeing enough brake area, and ensuring brake effect. The heat dissipation holes are arranged on a middle position of the working surface, thereby increasing the heat dissipation performance of the brake disc, and reducing the possibility of thermal fragment. The flange surface which is connected with the brake disc and the hub is arranged on the outer side of a connecting column, thereby being capable of achieving the arrangement of other elements of the heavy duty vehicle, and fixing moment of a bolt is bigger than the fixing moment when the bolt is designed on the inner side.

Description

A kind of heavy goods vehicles brake disc
(1) technical field
The utility model relates to automobile component technical field, particularly a kind of heavy goods vehicles brake disc.
(2) background technique
The break of heavy goods vehicles is formed by a plurality of component-assembled such as brake disc, wheel hubs at present, wherein brake disc is one of key components and parts of break, the performance of brake disc directly has influence on the performance of braking system, brake disc when work heating value is easy to more greatly produce hot tearing and influences its operating life, the traditional braking dish is located at wheel hub flange connecting face and is connected the cylinder inboard, causes other component installing spaces limited.
(3) summary of the invention
The technical problems to be solved in the utility model has provided a kind of heavy goods vehicles brake disc, has reduced the possibility of hot tearing, and other component installing spaces increase.
The utility model is realized by following measure: a kind of heavy goods vehicles brake disc, comprise disk body, and it is characterized in that: described disk body is connected an end and is provided with two working surfaces with brake slipper, is provided with a plurality of radiation holes in the middle of two working surfaces.
Radiation hole described in the utility model evenly distributes along the working surface circumference.
The end that disk body described in the utility model is connected with wheel hub is provided with the outwards outstanding flanged surface that has bolt hole.
The beneficial effects of the utility model:
1. be provided with two working surfaces, guaranteed enough brake areas, guaranteed braking effect;
2. radiation hole is left in the working surface neutral position, has improved the heat dispersion of brake disc, has reduced the possibility of hot tearing;
3. brake disc is located at the outside that is connected cylinder with wheel hub flange connecting face, can realize other planning of heavy goods vehicles like this, and the fixed end taken about the point of fixation of bolt is bigger in the inboard than design.
(4) description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the B-B revolved section schematic representation of Fig. 1.
1 flanged surface among the figure, 2 connect cylinder, 3 radiation holes, 4 working surfaces.
(5) embodiment
A kind of heavy goods vehicles brake disc comprises disk body shown in Fig. 1 .2, and described disk body right side and brake slipper are provided with a plurality of radiation holes 3 in the middle of being connected with two working surfaces, 4, two working surfaces 4; Described disk body left side is connected with the outwards outstanding flanged surface that has bolt hole 1 with wheel hub, and flanged surface 1 and working surface 4 intermediate portions are for being connected cylinder 2.
Radiation hole 3 described in the utility model evenly distributes along working surface 4 circumference.
Be provided with a plurality of radiation holes 3 between two working surfaces 4 of the utility model, improved the heat dispersion of brake disc, reduced the possibility of hot tearing; Brake disc links with wheel hub or miscellaneous part by the outstanding laterally flanged surface 1 in left side, connects by bolt, connects cylinder 2 parts and can arrange other elements that are adapted to heavy goods vehicles, makes brake structural compact and reasonable more.

Claims (3)
