Description

Self-cooling brake hub

Technical Field

The utility model relates to a brake hub technical field specifically is a brake hub of self-cooling.

Background

The brake hub is part of a drum brake system for an automobile. When braking, the piston applies pressure to two pairs of half-moon-shaped brake shoes to enable the brake shoes to cling to the inner wall of the drum chamber, and therefore friction is generated to stop rotation of the wheel. The brake drum is generally made of HT200-300 (namely gray cast iron), the matrix structure mainly comprises pearlite and a small amount of ferrite and cementite, and the graphite mainly comprises A grade, long sheet shape and 4-6 grade length, so that the effects of heat dissipation, friction performance increase and brake noise reduction are achieved. Being cast iron, it is resistant to wear, but after all is brittle and may break down upon ageing.

The radiating effect of the current brake hub is poor, so that an internal component is easy to generate overstocked large-amount heat energy, and the service life of the brake hub is seriously influenced, therefore, a novel self-cooling brake hub is urgently needed to be developed to solve the existing problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a braking hub of self-cooling to it is relatively poor to solve the present braking hub radiating effect who provides in the above-mentioned background art, leads to the easy a large amount of heat energy of overstock that produce of inner assembly, has seriously influenced braking hub's life's problem.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a braking hub of self-cooling, includes braking hub main part, the surface of braking hub main part is provided with the installation slotted hole, installs hub circle in the braking hub main part, the radiating groove has been seted up on the surface of hub circle, the inside mounting groove that is provided with of hub circle, mounting groove internally mounted has the bearing main part, bearing main part internally mounted has the bearing ball, and the axle collar is installed to the front end of bearing main part, the brake shoe piece is installed to the rear end of bearing main part, installs radiating fin on the brake shoe piece.

Preferably, the brake hub main body is of a ring-shaped gray cast iron structure.

Preferably, the surface of the radiating fin is provided with a radiating hole.

Preferably, the radiating fins are made of two groups of semicircular sheets.

Preferably, the brake shoe is tightly clamped with the inner part of the hub ring.

Preferably, the mounting slot holes are provided with eight in total.

Compared with the prior art, the beneficial effects of the utility model are that:

the heat dissipation grooves are formed in the surface of the hub ring, so that the inner bearing assembly can be quickly cooled, the brake shoe is installed at the rear end of the bearing main body, the heat dissipation fins are installed on the brake shoe, heat generated by the bearing part can be conducted conveniently, and the heat dissipation holes are communicated with the outside, so that the effect of wind mixing and cooling is achieved.
