As an improvement of the scheme, the plane of one side surface of the sawtooth passes through the axis of the brake shoe.
As an improvement of the scheme, counter bores are formed in the openings, close to the end portions of the rivets, of the mounting holes in the brake shoe and the positioning plate, and the bottom surfaces of the counter bores are flat surfaces.
As an improvement of the scheme, after the rivet is riveted, the height of the end part of the rivet, which is higher than the surface of the positioning plate, is not more than 2 mm.
As an improvement of the scheme, the mounting holes are uniformly distributed on the positioning plate and the brake shoe plate at the positions of two sides of the brake tendon, and the number of the mounting holes on each side is not less than 4.
Has the advantages that: according to the brake shoe assembly capable of stably braking, the brake shoe is riveted with the positioning plate, meanwhile, the brake shoe and the positioning plate are provided with the mutually meshed sawteeth, and the plane of one side surface of each sawtooth passes through the axis of the brake shoe. In the use, can adjust the brake shoe assembly installation direction, guarantee when the brake, the sawtooth is through the side atress of brake shoe plate axis, and this side is perpendicular with tangential force direction. The saw teeth are uniformly distributed on the surface of the brake shoe, so that the surface of the brake shoe is uniformly stressed and is not easy to deform, and the friction plate is fully contacted with the inner edge of the brake drum and is stably braked in the braking process.
The brake shoe assembly with stable braking ensures that the brake shoe is stressed uniformly in the braking process and improves the stability of the braking process by arranging the positioning plate which is contacted with the brake shoe in a sawtooth meshing mode.

Detailed Description
The present invention will be further illustrated with reference to the accompanying drawings and specific embodiments, which are to be understood as merely illustrative of the invention and not as limiting the scope of the invention. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
As shown in fig. 1 and 2, the brake shoe assembly which can be stably braked comprises a brake shoe 1 and brake tendons 2, wherein the brake shoe 1 is made of a semicircular arc-shaped steel plate, the brake tendons 2 are semicircular annular steel plates arranged on the concave side surfaces of the brake shoe 1, the number of the brake tendons 2 is two, the two brake tendons are arranged in parallel, and the brake tendons 2 are welded with the brake shoe 1. The brake shoe 1 is also provided with a positioning plate 3 outside, the positioning plate 3 is an arc-shaped plate attached to the brake shoe 1, the contact surface of the positioning plate 3 and the brake shoe 1 is provided with mutually meshed sawteeth 5, and the plane where one side surface of each sawtooth 5 is located passes through the axis of the brake shoe 1.
Corresponding mounting holes are uniformly formed in the positioning plate 3 and the brake shoe 1 as shown in fig. 3, the mounting holes are circular through holes, the rivet 6 penetrates through the mounting holes to rivet the positioning plate 3 and the brake shoe 1, counter bores are formed in openings, close to the end portions of the rivet 6, of the mounting holes in the brake shoe 1 and the positioning plate 3, the bottom surfaces of the counter bores are flat surfaces, and the rivet 6 is prevented from being in contact with arc-shaped surfaces of the positioning plate 3 and the brake shoe 1 at two ends when in riveting to cause riveting and untightening.
