Description
Technical field
The invention belongs to automotive fields, are a kind of auxiliary devices reducing windage at automobile case wheel arch specifically.
Background technology
Disk brake is a kind of brake apparatus of automobile, and in disk brake, brake disc is rotating element, caliper
It is retaining element.When automobile brake, the brake block on caliper is pressed on the surface of brake disc under the action of hydraulic system, makes
Huge frictional force is generated between brake block and brake disc, to achieve the effect that braking.But it will produce during braking big
The heat of amount, and these heat overwhelming majority are absorbed by disk brake, and the temperature of disk brake is made drastically to increase, if not in time
Heat is dispersed, it is easy to so that disk brake is deformed upon, influence the braking effect of disk brake
Currently, in order to radiate to disk brake, most automobile cases is all designed at the position of wheel on the market
One arc-shaped wheel arch, wheel arch can make air-flow blow over disk brake, take away the heat on disk brake, and then reduce disk
The temperature of formula brake.But in the driving process of automobile, direction when blowing air over body of a motor car can be upset by taking turns the presence of arch, be increased
The running resistance of big automobile, and the speed of running car is faster, the resistance that wheel arch is brought is bigger, and automobile overcomes resistance to be consumed
Energy it is more.In order to reduce the influence for the windage that wheel arch is brought, there is the arch of the wheel on some automobile cases to be designed to half
Shape is opened, but the wheel arch of half-open shape is unfavorable for the rapid dispersion of heat, so that disk brake is in the overlong time of high temperature, this very may be used
It can lead to the hydraulic pressure oil gasification in hydraulic system, influence the braking effect of disk brake, threaten traffic safety.
