Description
Technical Field
The utility model relates to the technical field of brake hubs, in particular to a brake hub capable of being cooled rapidly.
Background
The brake hub is part of a drum brake system of an automobile, and during braking, a piston applies pressure to two pairs of half-moon-shaped brake shoes to enable the brake shoes to cling to the inner wall of a drum chamber, so that friction is generated to stop rotation of wheels. The brake hub 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.
When current car brake hub uses, because its intensity is low, and the intensification is fast when using, and the cooling is slow simultaneously, after frequent braking, brake hub itself just can gather more heat and can't in time cool down by oneself, and adopts the water spray cooling, can lead to brake hub metallographic structure to change again to cause the condition that brake hub became invalid, consequently, but we have proposed a brake hub solution problem that can cool down fast in order to solve this a series of problems.
