Brake shoe assembly for agricultural tricycle

Abstract

The invention discloses a brake shoe assembly for an agricultural tricycle, which comprises a brake shoe, a brake shoe tendon, a friction plate, a center sleeve and a brake shaft cushion block, wherein two right-angled trapezoids are symmetrically cut off from the two sides of the left end of the brake shoe, so that the width W1 at the left end of the brake shoe is smaller than the width W of a bent steel plate; the left end of the brake shoe is connected with the middle part of the brake shoe through the inclined sides of the right-angled trapezoids; two right-angled triangles are symmetrically cut off from the two sides of the right end of the brake shoe, so that the width W2 at the right end of the brake shoe is smaller than the width W of the bent steel plate; the inclined sides of the right-angled triangles form an outer side at the right end of the brake shoe; the width W3 of the center sleeve is larger than the width W1 at the left end of the brake shoe; and the width W4 of the brake shaft cushion block is equal to the width W2 at the right end of the brake shoe. The brake shoe assembly has the benefits that the sensitivity and the brake torque of the brake shoe assembly are improved; and meanwhile, the energy resources are saved, and the technology is simplified.

Description

technical field [0001] The invention relates to the technical field of vehicle brakes, in particular to a brake shoe assembly of an agricultural tricycle. 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 shown agricultural tricycle brake shoe assembly 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 composed of a width W The steel plate is stamped and then bent into a half-moon shape. The friction plate 3 is bonded to the outer side of the brake shoe 1, the brake rib 2 is welded to the inner side of the brake shoe 1, and the center sleeve 4 is welded to the brake shoe. 1 and the left end of the brake hoof 2, the brake shaft cushion block 5 is welded on the right end of the brake shoe 1 and the brake hoof 2. combine ...

AI Technical Summary

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, welding tumors are prone to occur, which affects the next step of assembly and Grinding process is required for use; (2) With the continuous improvement of users' requirements on the braking performance and load capacity of the brake shoe assembly, the existing state can no longer meet the needs of the market, exposing poor braking sensitivity, braking The problem of insufficient torque
