Embodiment Construction
[0010] The present invention will be described in detail below in conjunction with accompanying drawing: figure 1 , 2 As shown, a motor vehicle brake shoe according to the present invention is composed of an arc-shaped steel sheet panel 1 and two adjacent arc-shaped ribs 2 vertically arranged in the middle of the inner arc surface of the steel sheet panel 1. It is formed by welding, and a horizontal connection bushing 3 is welded in the middle shaft hole of a circular end of the arc-shaped rib plate 2, that is, the bushing at the big R is changed from the original half-wrapped to the current full-wrapped , which increases the overall strength of the bushing, while ensuring the stability of the entire iron shoe during use; the two arc-shaped ribs 2 at the other end are provided with a semicircular roller shaft seat 5 on the flat end surface 4, and the steel The sheet panel 1 is provided with a left and right row of evenly distributed brake pad holes 6 respectively located outs...

A motor vehicle brake iron shoe is formed by welding an arc-shaped steel sheet panel and two adjacent arc-shaped rib plates vertically disposed in a middle position of the inner arc surface of the steel sheet panel; a transverse connection shaft sleeve is welded in middle shaft holes at one circular end parts of the arc-shaped rib plates; semicircular roller shaft seats are arranged on the flat end faces of the other end parts of the two arc-shaped rib plates, a left row of brake pad holes and a right row of brake pad holes positioned at the outer sides of the two arc-shaped rib plates are formed in the steel sheet panel, at least one connecting column playing a role in reinforcing is welded between the arc-shaped rib plates; the two ends of the arc-shaped rib plates are exposed at the twoend edges of the steel sheet panel; the outer sides of the semicircular roller shaft seats are each provided with a U-shaped reinforcing baffle plate; and a reinforcing pin is arranged between the parts, adjacent to the reinforcing baffle plate, at the inner sides of the arc-shaped rib plates. The motor vehicle brake iron shoe has the characteristics of simple structure, convenient and reliable use, high structural strength, good fit with brake pads, prolonged service life, and the like.
Description
technical field [0001] The invention relates to a motor vehicle brake shoe, which belongs to the technical field of motor vehicle brake components. Background technique [0002] The brake shoe refers to the brake accessory that is pushed outward by the action of the brake cam or push rod and suppresses the brake drum to play the role of motor vehicle brake. It is installed on the brake drum and is a part of the motor vehicle brake system. One of the key safety components. [0003] The shape of the existing brake shoes is like a half-moon. When the brakes are stepped on, the two half-moon-shaped brake shoes are stretched out under the action of the brake wheel cylinder to support the brake shoes and bring the connected brake shoes through the brake shoes. The disc rubs against the inner wall of the brake drum to slow down or stop. At present, the brake shoe is formed by stamping a steel sheet panel and two parallel arc-shaped rib plates. Due to the simple structure, the hol...
