Abstract
The invention relates to a double-layer high-strength high-abrasion resistance brake pad and a production method. The double-layer high-strength high-abrasion resistance brake pad comprises a friction working layer, a riveting layer or an adhesive layer, wherein the outer layer of the brake pad is provided with the friction working layer, while the inner layer is provided with the riveting layer or the adhesive layer; the inner layer and the outer layer are combined to form the double-layer high-strength high-abrasion resisting brake pad; the friction working layer improves the abrasion resistance and braking comfort of the brake pad on the premise of ensuring use strength; and the riveting layer or the adhesive layer does not participate in friction. The brake pad is of a double-layer layered brake pad structure, and the friction working layer is a high-abrasion resistance layer and adopts materials with higher cost but excellent abrasion resistance; meanwhile, the riveting layer or the adhesive layer adopts materials with relatively low cost but higher impact shear-resisting strength; therefore, both layers are combined to form the high-strength high-abrasion resistance brake pad which not only solves the problem of low strength, but also improves the abrasion resistance of the brake pad and reduces the integrated cost.
Description
Technical field
The present invention relates to mechanical manufacturing field, be meant a kind of double-layer high strength and high abrasion-proof brake block and production method.
Background technique
Along with the fast development of China's road traffic industry, automotive industry, the travelling speed of automobile improves constantly, and carrying capacity also constantly increases, and requires the safety brake parts-brake block of automobile on usability new breakthrough will be arranged.
In recent years, international, the domestic prices of raw and semifnished materials one tunnel skyrocketed, and domestic labor cost constantly increases, causing the brake block price also is one to rise and rise again, it is very helpless that the terminal use of brake block seems, has to bear owing to raw material, and the labour force is gone up and the cost of rise.
What therefore, need on the market is the higher product of cost performance---high strength, high abrasion, low cost.Domestic friction material industry doing one's utmost to make great efforts to adapt to this market demand, does not still but have the breakthrough of matter yet on product, promptly do not guarantee to accomplish high abrasion, high strength, so that cause brake block frangible when Emergency braking, so generation traffic accident easily.As accomplish high-intensityly, and its wear resistance has very heavy discount again, causes shorten the working life of brake block, and the user is dissatisfied.Two aspects are all ready-made, and price is too high again, and the user does not generally approve.
