Description
Technical field
The utility model relates to motor vehicle brake technical field, particularly a kind of vehicle brake brake disc and corresponding vehicle brake, vehicle.
Background technique
Automobile brake mode has disc type brake and drum braking two kinds, and what Hyundai Motor was conventional is disc type brake.Brake disc and brake disc are the critical components of disk type braker, and when touching on the brake in vehicle travel process, brake caliper is clamped brake disc and played the effect of slowing down or stopping.
The rear brake disc of existing structure is in long-term working procedure, due to repeatedly braking and and the frictional force produced between friction plate can produce amount of heat, so need brake disc to have enough intensity, rigidity, crackle and distortion is there is to prevent brake disc itself, also to ensure that brake disc dispels the heat effectively in time, avoid causing brake judder, even heat fade was lost efficacy and was made brake failure.
Existing one chip rear brake brake disc, is suitable on pony car, and strength and stiffness are poor and heat dissipation potential is poor;
The structure of the common brake disc of existing double-disk, primarily of holder housing and the double-deck disk body two-part composition of hollow, additional heat spoke between hollow double-deck disk body.The circumferential surface of the holder housing of the brake disc of this structure is directly connected with the card of disk body and rectangular relation therebetween, heat radiation spoke mostly is the straight muscle with center of circle conllinear, be unfavorable for that the moving air produced by vehicle wheel rotation imports heat radiation spoke place, thus brake disc easily produces thermal distortion, straight muscle structure is unfavorable for heat radiation simultaneously, causes brake disc radiating effect poor.
Model utility content
In view of this, the utility model is intended to propose a kind of vehicle brake brake disc, and the radial dimension of the exterior edge face of its holder housing is less than interior edge face, to increase the strength and stiffness of brake disc, effectively suppresses the warpage distortion of brake disc working surface simultaneously.
