Description

Novel braking piece with abrasion indicating function

Technical Field

The invention belongs to the technical field of brake pads for automobiles, and particularly relates to a novel brake pad with a wear indication function.

Background

The brake block is the most critical safety part in the braking system of the automobile, and the brake block plays a decisive role in the braking effect of the automobile. The brake pad is generally composed of a steel mounting plate and a friction plate made of friction material, the friction plate and the mounting plate are bonded through an adhesive layer, and a heat insulation layer is generally arranged between the friction plate and the mounting plate. In the in-service use in-process, the friction disc of braking piece can become thin under wearing and tearing, need change when general thickness is less than 2mm, and its thickness is difficult to inspect at the maintenance process to current friction disc, generally need monitor its thickness through installing electronic sensor in addition, has improved manufacturing cost greatly, and the reliability is not enough simultaneously, when the electronic system breaks down, leads to the control to become invalid easily.

Disclosure of Invention

The purpose of the invention is as follows: the invention aims to provide a novel brake pad with a wear indicating function aiming at the defects in the prior art.

The technical scheme is as follows: in order to achieve the above object, the present invention provides a novel brake pad with a wear indication function, comprising a mounting plate and a friction pad, wherein the mounting plate is provided with a connecting part for connecting a brake device, the friction pad is adhered to the mounting plate, the friction plate comprises a central plate and side plates, the side plates are symmetrically arranged at two sides of the central plate, the central plate is provided with an indicating block facing to one side of the center of the brake disc in a mounting state, the indicating block is a bulge with the same thickness as the central piece, the end part of the indicating block is provided with an observation groove which is a rectangular groove, the opening of the observation groove is positioned on the contact surface of the central piece and the mounting plate, the observation groove comprises a primary indicating groove and a secondary indicating groove, the primary indicating groove and the secondary indicating groove bottom form a step surface structure, the secondary indicating groove bottom surface is 2mm away from the center piece and the mounting plate contact side surface, and the primary indicating groove bottom surface is 4mm away from the center piece and the mounting plate contact side surface.

As a modification of the scheme, the bottom surfaces of the primary indicating groove and the secondary indicating groove are coated with pigments with different colors.

As an improvement of the scheme, the areas of the bottom surfaces of the primary indicating groove and the secondary indicating groove are not less than 0.5 square centimeter.

As a refinement of the solution, the secondary indicator groove is closer to the central piece.

As a improvement of the scheme, the bottom of the primary indicating groove is coated with a green pigment, and the bottom of the secondary indicating groove is coated with a red pigment.

Has the advantages that: according to the novel brake pad with the wear indication function, the indication block is positioned on the outer side of the central pad when in use, and the indication block is positioned on the outer side of the brake assembly when in use, so that a maintainer can observe the indication block and the observation groove on the indication block. The bottom of the first-level indicating groove and the second-level indicating groove are coated with colored coatings, so that the maintainers can observe the bottom condition of the first-level indicating groove and the second-level indicating groove conveniently. In the actual use process, the friction plate is worn and thinned continuously, when the thickness of the friction plate is reduced to a certain degree, the bottom of the primary indicating groove is lost due to wear, and when the thickness is reduced continuously, the bottom of the secondary indicating groove is lost due to wear, namely the brake pad needs to be replaced. Whether the maintainer is lacked through observing that first order instruction groove and second grade instruction groove have the bottom of colour can roughly know the friction disc wearing and tearing condition, and then judges whether need change the braking piece.

The novel brake piece with the abrasion indicating function is simple in structure, a maintenance worker can observe the abrasion condition of the brake piece, the judgment of whether the brake piece is replaced or not can be made in time, and meanwhile, the cost is greatly reduced because an electronic sensor is not needed for measuring the thickness of the friction piece.
