The bolts 5 are tightly fixed in the reserved positioning groove of the brake pad 2. A concave groove 6 is provided on the outer surface of the lower end of the convex positioning strip 3. An elastic sheet 7 is fixed on the inner surface of the concave groove 6. A triangular convex head 8 is provided on the outer surface of the elastic sheet 7. The triangular convex head 8 is clamped on the inner surface of the brake pad 2. During installation, sliding positioning is adopted, the bottom is clamped and fixed, and the back bolt is locked and installed. The fixing is firm, the installation mechanism is simple, and the cost is low.

[0030] The inner surface of the convex positioning groove 4 of the brake pad 2 is provided with a triangular positioning groove 9, and the triangular convex head 8 of the elastic sheet 7 is clamped on the inner surface of the triangular positioning groove 9, so that after the brake pad 2 is slidably fitted, the bottom is clamped and positioned by the triangular convex head 8 of the elastic sheet 7, and the clamping installation is stable, which prevents the brake pad 2 from falling off when the bolt 5 is loosened. The installation is convenient and stable. When disassembling, press the elastic sheet 7 to drive the triangular convex head 8 to disengage from the triangular positioning groove 9, and then twist the bolt 5 to loosen and squeeze it, and the brake pad 2 can be slid down and pulled out, which is convenient for disassembly;

[0031] A convex opening 10 is provided on the back of the back plate 1, and an internal thread is provided at the convex positioning strip 3. The bolt 5 is inserted along the convex opening 10 and is connected to the inner surface of the convex positioning strip 3 through a thread, so that the bolt 5 can be installed conveniently, and the bolt 3 can tighten and fix the brake pad 2 (easy installation);

[0032] The elastic sheet 7 adopts a bent sheet structure, which is made of elastic steel sheet and has good elastic clamping performance;

[0033] The outer surface of the stud of the bolt 5 is sleeved with a compression spring 11, which compresses the bolt 5 in the reverse direction and can be reversely squeezed and locked to prevent the bolt 5 from loosening and slipping;

[0036] The outer surface of the brake pad 2 is covered with a friction layer 200. The surface coating is to increase the friction coefficient of the new brake pad before it is run-in, so that a good braking effect can be obtained as soon as the brake pad is replaced. The brake pad 2 is a component composed of a chip and a friction lining or a friction material layer. The friction layer 200 adopts the coating on the brake pad as silicon carbide, which has a friction effect. Compared with other existing surface-treated brake pads, it has incomparable advantages, such as: extremely strong thin layer corrosion resistance (neutral salt spray test NSS ≥ 240h), no hydrogen embrittlement, high permeability, strong heat resistance, strong chemical medium resistance stability, etc., which greatly enhances the rust and wear resistance of the brake pad and extends the service life of the brake pad.
