Problems solved by technology

Through the study of the structure, static and dynamic properties of shells, leaves, fish and other organisms, it is found that the functions of the organisms such as wear resistance, extrusion resistance, and crack resistance are related to the shape, characteristic size, and distribution of the strengthening unit. It has a close relationship with the quantity, and there is no record of applying bionics to brake pads in the prior art

preparation example Construction

[0036] A method for preparing a brake pad with a bionic structure, comprising the following steps,

[0037] (1) Design and manufacture the bionic reinforced skeleton according to the bionic coupling distance;

[0038] (2) Weld or inlay the bionic reinforced skeleton on the brake pad substrate;

[0039] (3) Pre-treat the surface of the brake pad substrate and the bionic reinforced skeleton;

[0040] (4) Fill the gaps of the bionic reinforced skeleton with wear-resistant materials and compact and solidify them.

[0041] The embedding on the brake pad substrate means that a plurality of grooves are provided on the brake pad substrate for embedding the bionic reinforced skeleton, and then the whole bionic reinforced skeleton is embedded into these grooves.

[0042] The pretreatment of the surface of the brake pad base and the bionic reinforced skeleton includes the following steps,

[0043] (1) Texturize the surface of the brake pad substrate and bionic reinforced skeleton or p...

specific Embodiment 1

[0050] Specific embodiment 1: A crank press brake pad, according to the working conditions and usage requirements of the crank press, a plant leaf vein-shaped bionic reinforced skeleton is selected, and the distance between two adjacent side veins of the plant leaf vein-shaped bionic reinforced skeleton The volume ratio between the bionic reinforced skeleton and the filled wear-resistant material is 1 / 8, the height of the bionic reinforced skeleton is 3mm, the brake pad substrate material is cold-rolled steel plate, and the bionic reinforced skeleton material is carbon structural steel. The reinforced frame is fixed on the brake pad substrate by welding. After the brake pad base plate and the bionic reinforced skeleton are welded and fixed, the surface is roughened, and then the surface is polished with sandpaper. First, use 7% NaOH solution to remove oil, then use 70°C hot water to rinse, and then use 20% h 2 S0 4Pickling to remove scale, then rinsing with hot water at 70°C...

Abstract

The invention relates to the field of brake pads, especially to a brake pad with a bionic structure and a preparation method thereof. The brake pad comprises a brake pad substrate (1). A bionic reinforced framework (2) is arranged on one surface of the brake pad substrate (1); and compacted wear-resistant materials (3) are arranged in a gap of the bionic reinforced framework (2). The brake pad has the advantages of less friction coefficient variation, less thermal wear, higher reliability and longer service life at the high temperature.

Description

technical field [0001] The invention relates to the field of brake pads, in particular to a brake pad with a bionic structure and a preparation method thereof. Background technique [0002] The brake pad is a device that converts kinetic energy into heat energy through friction to achieve braking and releases heat energy to the environment in time. It is widely used in sports machine tools and motor vehicles. Its performance is directly related to the safe and reliable operation of machine tools and motor vehicles. However, the common brake pads in the prior art have a large change in friction coefficient and large thermal wear at high temperatures, so the reliability is low and the service life is short. However, if the prior art needs to improve the above performance of the brake pads, it is generally through research and development. It is realized by new material formula and improved friction material performance. This method of improving the performance of brake pads b...
