Description

Technical Field

[0001] The utility model belongs to the technical field of disc brake equipment, in particular to a disc brake fixed chain plate. Background Art

[0002] In short-distance travel, bicycles, electric vehicles and motorcycles are still a widely used means of transportation in today's society due to their advantages such as lightness, flexibility and environmental protection. Some existing electric vehicles, motorcycles, etc. use expansion brakes or drum brakes. The expansion brakes or drum brakes are small in size but have a long braking distance and the braking effect is not good enough. The disc brakes corresponding to the expansion brakes and drum brakes are better than the two in braking effect. The braking distance during emergency braking is much shorter than that of drum brakes. Disc brakes are controlled by hydraulics. The main components include brake discs, slave cylinders, brake calipers, oil pipes, etc. The brake disc is fixed on the wheel and rotates with the wheel. The slave cylinder is fixed on the bottom plate of the brake. The two friction plates on the brake caliper are respectively installed on both sides of the brake disc. The piston of the slave cylinder is acted on by the hydraulic pressure transmitted from the oil pipe to push the friction plate to the brake disc for friction braking.

[0003] In order to improve the braking effect of vehicles, users often convert the original expansion brake or drum brake into a disc brake. Since various types of bicycles, electric vehicles, motorcycles, etc. have different frame shapes, different wheel sizes, and different speeds, the brake discs to be used have different size requirements. As a result, the fixed chain plate connecting the bracket and the brake disc cannot be universal, resulting in inconvenient installation. Therefore, a disc brake fixed chain plate is proposed to solve the above problem. Utility Model Content
