Abstract

The invention provides a powerful balance brake device comprising a brake drum, a bottom plate, a left brake shoe, a right brake shoe and cam mechanisms. The left brake shoe and the right brake shoe are oppositely arranged to form two pairs of opposite end faces, guiding holes are formed in the two end faces of the left brake shoe and the two end faces of the right brake shoe, and one cam mechanism is arranged between each pair of opposite end faces of the left brake shoe and the right brake shoe; and each cam mechanism comprises a cam shaft, a guide shaft and a cam, the cams are arranged on the cam shafts, through holes are formed in the middle portions of the guide shafts, the cam shafts penetrate through the through holes, one end of each guide shaft is inserted into the corresponding guiding hole of the left brake shoe, and the other end of each guide shaft is inserted into the corresponding guiding hole of the right brake shoe. The technical problems that the braking force is small and braking is not sensitive are solved.

Description

technical field [0001] The invention relates to the technical field of vehicle components, in particular to a strong balanced braking device. Background technique [0002] Drum brakes generally adopt drum brakes. Drum brakes are composed of rotating parts and fixed parts, including brake bottom plates, brake wheel cylinders, brake shoes, etc. Drum brakes have a cast iron piece similar to a tambourine, called a brake. The drum, which is fixed to the tire and turns at the same speed. Drum brakes have lower cost and higher absolute braking force, and are more widely used on the rear wheels of vehicles. But its wear rate is high, so the overall cost is high at the same time. The brake shoe refers to the accessories that are pushed outward by the force of the brake wheel cylinder or push rod to suppress the brake drum to perform the braking effect. It is installed on the brake drum. It is one of the key safety parts in the automobile braking system. [0003] The shape of the b...
