Abstract

The utility model relates to the field of automobile parts, in particular to a novel automobile brake disk. The technical scheme is follows: the novel automobile brake disk comprises a brake disk and a connecting disk which are mutually connected, wherein a plurality of through heat radiating holes and a plurality of groups of non-through heat radiating holes, which are distributed circumferentially, are arranged in the disk surface of the brake disk, the diameters and the depths of the non-through heat radiating holes are in an inverse ratio; and a plurality of groups of air ducts pointing the center of an axial hole and being communicated with the axial hole and a plurality of groups of heat radiating grooves pointing the center of the axial hole and being not communicated with the axial hole are arranged on the outer edge of the brake disk. On the basis of ensuring the heat radiating effect of the brake disk, part of the through heat radiating holes in the disk surface of the traditional brake disk are changed into non-through heat radiating holes, partial communicated air ducts on the outer edge of the brake disk are changed into non-communicated heat radiating grooves, thus the volume of an upper cavity of the brake disk is reduced, therefore, the integral strength is improved. The novel automobile brake disk has the advantages of simple structure, easy manufacture and low cost, is improved in integral strength on the premise of ensuring heat radiating efficiency, and is prolonged in service life.

Description

A kind of novel automobile brake brake disc

Technical field

The utility model relates to the auto parts and components field, is specifically related to a kind of novel automobile brake brake disc.

Background technique

In the vehicle devices such as automobile, braking mechanism generally adopts disc brake mechanism, and it is in brake process, and brake disc will generate heat rapidly.Therefore, the heat radiation of brake disc is the problem of necessary consideration in the optimization of vehicle design.For present brake disc, its main heat dissipation design is distribute at disk body and run through the cylindrical heat-radiating through hole of disk body, thereby the heat dispersing surface of increase disk body to be provided with the air channel that is communicated with axis hole in the disk body outer rim in addition; For improve brake disc thermal diffusivity, usually radiation hole and air channel quantity are more, although satisfied the heat radiation needs, but because brake disc is the thin-desk structure, wherein the distribute cavity of various connections greatly reduces the bulk strength of brake disc, has reduced its working life.

The model utility content

The purpose of this utility model is exactly the defective that exists for prior art, and the novel automobile brake that a kind of thermal diffusivity is good and intensity is high brake disc is provided.

Its technological scheme is: comprise interconnected brake disc and land, wherein on the card of brake disc along many groups that circumferentially distribute penetrating radiation hole and the impermeable radiation hole of many groups, and diameter and the degree of depth of respectively organizing impermeable radiation hole are inverse ratio; The outer rim of brake disc distribute that many groups are pointed to the axis hole center of circle and the air channels that are communicated with axis hole and many groups sensing axis hole center of circle but with the disconnected heat radiation groove of axis hole.Namely on the basis that guarantees the brake disc radiating effect, change the penetrating radiation hole of part on the existing brake card into not penetrating radiation hole, part on the brake disc outer rim is communicated with the air channel and changes disconnected heat radiation groove into, above-mentioned design has reduced the volume of brake disc upper plenum, thereby has improved bulk strength.

Because in the brake disc rotary course, because the diameter of penetrating radiation hole both sides consistent (such as the cylindrical heat-radiating hole of routine), the pressure of its both sides of brake disc is suitable, therefore, the Air Flow in the radiation hole is less, and its radiating efficiency can not brought into play efficiently, therefore penetrating radiation hole is designed to taper shape, namely an end diameter is large, and an end diameter is little, increases substantially the air mass flow in the radiation hole; For increasing heat radiation area, and interactive with the rotation of brake disc, improving radiating effect, air channel and heat radiation groove can be designed as arc.

The utility model is simple in structure, easy to manufacture, with low cost, and it has improved whole intensity under the prerequisite that guarantees radiating efficiency, prolonged working life.

Embodiment

With reference to Fig. 1-Fig. 4, a kind of novel automobile brake brake disc, comprise interconnected brake disc 1 and land 2, wherein on the card of brake disc 1 along circumferentially distributing successively from outside to inside one group of penetrating radiation hole 5, one group of not penetrating little radiation hole 4 and one group of not penetrating large radiation hole 3, wherein penetrating radiation hole 5 is conical, not penetrating little radiation hole 4 and one group of not penetrating large radiation hole 3 are cylindrical, three's diameter is according to penetrating radiation hole 5, the diameter of not penetrating little radiation hole 4 and not penetrating large radiation hole 3 increases (wherein penetrating radiation hole 5 diameters are as the criterion with large end) successively, but the degree of depth reduces (wherein penetrating radiation hole runs through brake disc) successively according to said sequence; The outer rim of brake disc 1 be interspersed that many groups are pointed to the axis hole center of circle and the air channels 6 that are communicated with axis hole 8 and the sensing axis hole center of circle but with axis hole 8 disconnected heat radiation grooves 7; Air channel 6 and all side's of the being related to bar shapeds of heat radiation groove 7 also can be designed as arc.

Only more than relate to and to be a kind of specific embodiment, penetrating radiation hole wherein and not quantity and the particular location of penetrating radiation hole all can reasonably be adjusted, and just do not enumerate one by one at this.
