Problems solved by technology
[0003] The main problems are: (1) The width W3 of the center sleeve 4 is equal to the width W1 of the left end of the brake shoe 1. When the center sleeve 4 is welded to the brake shoe 1, weld bumps are prone to occur, which affects the next assembly and use , needs to be polished; (2) With the continuous improvement of the user's requirements on the braking performance and load capacity of the brake shoe assembly, the existing state can no longer meet the market demand, exposing the problems of poor braking sensitivity and insufficient braking torque question

Embodiment Construction
[0017] Below by embodiment, in conjunction with accompanying drawing, the present invention is described in further detail:
[0018] Such as Figure 4 , Figure 5 The heavy-duty vehicle brake shoe assembly shown is composed of a brake shoe 1, a brake rib 2, a friction plate 3, a center sleeve 4 and a brake shaft pad 5. combine Figure 6 It can be seen that the brake shoe 1 is a half-moon shape formed by punching and bending a steel plate with a width of W, the friction plate 3 and the brake rib 2 are also half-moon-shaped, and the friction plate 3 is bonded to the brake shoe 1 The outer side of the brake shoe 2 is welded on the inner side of the brake shoe 1, the center sleeve 4 is welded on the left end of the brake shoe 1 and the brake shoe 2, and the brake shaft pad 5 is welded on the brake shoe 1 and the brake shoe. Right end of tendon 2.
[0019] A plurality of welding bumps 1c are punched on the brake shoe 1 for welding with the brake shoe rib 2 . Both sides of the ...

The invention discloses a heavy-duty type vehicle brake shoe assembly which comprises a brake shoe, a brake shoe rib, a friction plate, a central sleeve and a brake axle cushion block, wherein right trapezoids are symmetrically peeled off from both sides of the left end of the brake shoe to ensure that the width W1 of the left end of the brake shoe is smaller than the width W of a bending steel plate, and the left end of the brake shoe is connected with the middle part of the brake shoe through the bevel edges of the right trapezoids; right triangles are symmetrically peeled off from both sides of the right end of the brake shoe to ensure that the width W2 of the right end of the brake shoe is smaller than the width W of the bending steel plate, and the outer side edges of the brake shoe are formed by the bevel edges of the right triangles; and the width W3 of the central sleeve is larger than the width W1 of the left end of the brake shoe, and the width W4 of the brake axle cushion block is equal to the width W2 of the right end of the brake shoe. According to the heavy-duty type vehicle brake shoe assembly, the sensitivity and the brake torque of the brake shoe assembly are improved, meanwhile, energy is saved, and the process is simplified.
Description
technical field [0001] The invention relates to the technical field of vehicle brakes, in particular to a heavy-duty vehicle brake shoe assembly. Background technique [0002] The brake assembly formed by assembling the brake shoe assembly and the brake disc is a set of brake safety components for the service brake and the parking brake. Such as figure 1 , figure 2 The heavy-duty vehicle brake shoe assembly shown is composed of a brake shoe 1, a brake rib 2, a friction plate 3, a center sleeve 4 and a brake shaft pad 5. The brake shoe 1 is a half-moon shape formed by stamping and bending a steel plate with a width of W. The friction disc 3 is bonded to the outer side of the brake shoe 1, and the brake rib 2 is welded to the Inside, the center sleeve 4 is welded on the left end of the brake shoe 1 and the brake shoe 2, and the brake shaft pad 5 is welded on the right end of the brake shoe 1 and the brake shoe 2. combine image 3 It can be seen that the two sides of the ...
