Problems solved by technology

[0002] In heavy-duty vehicles such as construction machinery, the brakes that are often used are generally hydraulic drum brakes. This type of brake usually adopts a brake shoe with a single-rib casting structure. The left and right brake shoes have only one brake rib plate, and the brake The shoes are made of castings, which are not only bulky and heavy, but also easily deformed during braking, and there is no explosive force at the moment of braking. After long-term use, the brake shoe is easy to crack and cause failure, especially for heavy and large construction machinery When the vehicle is damaged, reliable braking cannot be achieved, and safety cannot be guaranteed

Embodiment Construction

[0020] Such as figure 1 figure 2 A drum-type hydraulic double tendon shoe pin-type brake is shown, including a bracket 1, a hydraulic cylinder 2 fixed on the bracket 1, and left and right brake shoes 31, 32 symmetrically arranged on the bracket 1 , The left and right brake shoes 31,32 are double rib type brake shoes, and the slave cylinder 2 is covered with a slave cylinder dust cover.

[0021] Such as Figure 4 Figure 5 As shown, the left and right brake shoes 31, 32 have brake shoe skeletons, and the brake shoe skeletons are fixed by spot welding of two parallel steel rib plates 4 and steel curved panels 5 respectively, and the two rib plates 4 is also fixed with a side plate respectively, and the outer side of the curved panel 5 is fixed with a friction plate with a rivet. Therefore, the manufactured brake shoe has high rigidity and fastness, the manufacturing process is simplified, and the production cost is reduced.

[0022] Such as figure 1 figure 2 As shown, t...

Abstract

The invention relates to a drum-type hydraulic double-reinforcement shoe anchor pin type brake which comprises a bracket, a hydraulic branch pump, a left brake shoe and a right brake shoe, wherein the hydraulic branch pump is fixed on the bracket; the left brake shoe and the right brake shoe are symmetrically distributed on the bracket and are double-reinforcement type brake shoes; the top ends of the left brake shoe and the right brake shoe are respectively connected with a left support rod and a right support rod of the branch pump; and the upper ends of the left brake shoe and the right brake shoe are connected by a return tension spring, and the lower ends of the left brake shoe and the right brake shoe are respectively articulated with the bracket. The left and right double-reinforcement type brake shoes are provided with a brake shoe framework, and the brake shoe framework is respectively formed in such a way that two parallel steel rib plates and a steel cambered panel are fixedly combined. The two parallel rib plates are connected with the cambered panel in a spot welding way. The double-reinforcement type brake shoe has tiny elastic deformation at the moment of brake so as to generate great brake explosive force; the brake performance, the brake effect and the brake reliability are better than those of a common brake; and the invention is more suitable for the brake of heavy-duty and large engineering mechanical vehicles.

Description

technical field [0001] The invention relates to a brake for a vehicle, in particular to a drum-type hydraulic double-rib shoe pin-type brake. Background technique [0002] In heavy-duty vehicles such as construction machinery, the brakes that are often used are generally hydraulic drum brakes. This type of brake usually adopts a brake shoe with a single-rib casting structure. The left and right brake shoes have only one brake rib plate, and the brake The shoes are made of castings, which are not only bulky and heavy, but also easily deformed during braking, and there is no explosive force at the moment of braking. After long-term use, the brake shoe is easy to crack and cause failure, especially for heavy and large construction machinery When the vehicle is damaged, reliable braking cannot be achieved, and safety cannot be guaranteed. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the deficiencies of the prio...
