Wheel casing for forced ventilation/heat radiation to rim and brake

Abstract

The invention discloses a wheel casing for forced ventilation / heat radiation to a rim and a brake. A plurality of wheel casing spokes are fixedly arranged along circumferential direction uniformly at the radial direction between a wheel casing shell and a wheel casing hub; at the axial direction, the wheel casing spokes are composed of two left and right sections of transition transformed structures, the included angle of the acute angle of the left section to the vertical line of a wheel axis is b1, the included angle of the acute angle of the right section to the vertical line of the wheel axis is b2, and beta 1 is more than or equal to 8 degrees and is less than or equal to 30 degrees and beta 2 is more than or equal to 75 degrees and is less than or equal to 90 degrees; the rightmost ends of the wheel casing spokes cling to the surface of a wheel spoke plate tightly and extend to air vents on the wheel spoke plate, and are distributed alternately with the air vents; air flow is led to the air vents on the wheel spoke plate from the outer side of the wheel spoke plate along the axial direction and the radial direction of a wheel shaft through the wheel casing spokes with active axial flow orientation function and active centrifuge orientation function as well, the air flow submitted to active orientation flows through gaps between wheel rims and brake drums after flowing through the air vents at high speed, thereby realizing continuous forced ventilation / heat radiation to the wheel rims and the brakes simultaneously.

Description

technical field [0001] The invention belongs to the technical field of automobile brake safety and tire explosion-proof safety, and in particular relates to a wheel cover of an automobile. Background technique [0002] The wheel cover, wheel and brake of the automobile are all coaxially installed on the axle, the wheel cover is fixed on the outside of the wheel, and plays the role of decoration or protection of the wheel connecting bolts, and the inside of the wheel is the brake. When the car brakes frequently for a long time, it will cause the brakes and tires to continue to heat up, especially for cars equipped with drum brakes. The heat is not easy to dissipate, and high temperature will lead to a significant decrease in the friction coefficient of the brake, which in turn will cause the thermal decline of the braking performance of the car. If the braking time is too long, the heat generated by the brakes can lead to cracks in the brakes in extreme cases; in addition, t...

Problems solved by technology

Adding heat dissipation ribs to the brake drum will greatly increase the manufacturing cost, and make the space between the drum brake and the wheel rim narrower, resulting in poorer ventilation between the drum brake and the wheel rim
