Axle connecting plate and air pressure disc brake of support invisible composite structure of axle connecting plate

Abstract

The invention relates to a brake block axle connecting plate and an air pressure disc brake thereof, and belongs to the field of vehicle parts. According to the technical scheme, the brake block axle connecting plate comprises a connecting part located on the lower portion, the connecting part is of a plate-shaped structure, a shaft hole is formed in the lower portion of the connecting part, a plurality of axle connecting holes and an ABS alarm line mounting hole are formed in the periphery of the shaft hole, and the hole diameter of the shaft hole is smaller than that of a middle hole of a brake disc. The ABS alarm line mounting hole is positioned in a mapping range from a middle hole of the brake disc to the side surface; the limiting parts are located on the two sides of the upper portion of the connecting part and are symmetrically arranged on the two sides, the brake block is installed between the limiting parts on the two sides, the limiting parts are provided with guide pin connecting holes, external corners are filleted corners, and triangular wedge-shaped structures are arranged on the upper portions of the limiting parts. The brake caliper is in a brand new state, the brake caliper body is matched with the positions of the invisible support and the connecting plate, matched installation of the brake block is achieved, safe and effective braking is guaranteed, and the traditional mode that the brake block is fixed through the support is changed.

Description

Pneumatic disc brake with invisible composite structure of axle connecting plate and its bracket technical field [0001] This patent relates to a brake block axle connecting plate and its pneumatic disc brake, belonging to the field of vehicle parts. Background technique Most of existing vehicle assembly is still traditional drum brake, but with the implementation of the new GB7258 national standard, Disc brakes have gradually switched to the heavy commercial vehicle market due to their high braking energy efficiency and good heat dissipation. But the current pneumatic disc brake structure in order to ensure the structural strength and braking effect, usually the structure is relatively Thick, bulky, and relatively expensive to manufacture. [0004] Directly reducing the thickness of the product will lead to a reduction in structural strength, and there is a potential safety hazard. To achieve lightweight products In order to reduce the material cost, it is necessary...

[0003] However, in order to ensure the structural strength and braking effect of the current pneumatic disc brake structure, the structure is usually thicker, the volume is larger, and the manufacturing cost is relatively high.

[0004] Directly reducing the thickness of the product will lead to a decrease in structural strength, which poses a safety hazard
