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.
