Abstract

The invention discloses a two-direction and double-leading trailing shoe type brake for leading trailing shoe parking of an automobile, and belongs to the technical field of braking of automobiles. The two-direction and double-leading trailing shoe type brake for leading trailing shoe braking of the automobile comprises a bottom plate, a braking drum, a wheel cylinder, a first braking shoe, a second braking shoe, a first pulling rod, a second pulling rod, a fixing hinge pin, a parking pulling arm and a bar system. According to the two-direction and double-leading trailing shoe type brake for leading trailing shoe parking of the automobile, the bottom plate is fixed on a carriage axle, the braking drum is arranged on a hub, the wheel cylinder is fixed on the bottom plate, the first braking shoe and the second braking shoe are respectively arranged at two sides of the wheel cylinder, the fixing hinge pin is arranged at one side of the bottom plate, opposite to the wheel cylinder, and therefore, the function of the leading trailing shoe brake of the automobile can be achieved; the bar system and the parking pulling arm are arranged to achieve the function of the two-direction double-leading trailing shoe type brake of the automobile; when in braking for parking, the first braking shoe increases force for the second braking shoe through the bar system, or the second braking bar system increases force for the first braking shoe, so that the parking braking efficiency of the brake can be improved under a relatively small space.

Description

technical field [0001] The invention relates to the technical field of automobile braking, in particular to a two-way double-leading shoe type brake for driving leading shoes and parking. Background technique [0002] A brake is an automotive body part that slows down or even stops a moving car, stabilizes the speed of a car traveling downhill, and holds a stopped car still. The vehicle needs to perform frequent braking operations during driving. Since the braking performance is directly related to traffic and personal safety, the braking performance is one of the very important performances of the vehicle. [0003] The commonly used brake is a leading shoe brake, including a base plate, a brake drum, a pair of brake shoes, a wheel cylinder, a return spring, and a positioning pin. The cylinder, the return spring and the positioning pin are respectively arranged on the bottom plate, and the brake drum is installed on the wheel hub to rotate together with the wheel. When brak...
