Abstract

The invention discloses a two-way double-leading-shoe type brake for driving with leading shoes and parking, and belongs to the technical field of automobile braking. The two-way double-leading shoe type brake includes a base plate, a brake drum and a wheel cylinder, and also includes a first brake shoe, a second brake shoe, a first pull rod, a second pull rod, a fixed pin, The parking pull arm and the rod system, the present invention fixes the bottom plate on the axle, the brake drum is arranged on the wheel hub, the wheel cylinder is fixed on the bottom plate, and the first brake shoe and the second brake shoe are separately placed on the wheel cylinder. On both sides, the fixed pin shaft is set on the side of the bottom plate opposite to the wheel cylinder to realize the function of the leading shoe brake for driving, and realize the function of the two-way double leading shoe brake for parking through the setting of the lever system and the parking pull arm , and in the parking braking process, the first brake shoe increases the force of the second brake shoe through the rod system, or the second brake shoe increases the force of the first brake shoe through the rod system, which can be achieved in a relatively small Space to improve the parking brake performance of the brake.

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...
