Single-piston CBS brake caliper

Abstract

The invention discloses a single-piston CBS brake caliper comprising: a caliper body provided with a jaw used for clamping a brake disc; a main brake cylinder hole which is formed in the caliper body on one side of the jaw, wherein one end of the main brake cylinder hole faces the other side of the jaw and is provided with an opening; an linkage cylinder hole which is formed in the caliper body at the other end of the main brake cylinder hole along the axis of the main brake cylinder hole, wherein an opening communicated with the main brake cylinder hole is formed in one end of the linkage cylinder hole; a step piston which comprises a column part tightly sliding in the linkage cylinder hole and a step part tightly sliding in the main brake cylinder hole, wherein the head end of the step part is connected with the bottom end of the column part; a brake pad which comprises a movable brake pad and a fixed brake pad oppositely arranged in the jaw, wherein the fixed brake pad is attached to the other side of the jaw, and the movable brake pad is attached to the bottom end of the step part; a main brake oil inlet hole which is formed in the caliper body and is communicated with the main brake cylinder hole; and a linkage oil inlet hole which is formed in the caliper body and is communicated with the linkage cylinder hole. The CBS brake caliper is reasonable in structure and small in size, pedal motorcycles with small-specification hubs can be conveniently installed and used, and the production cost can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of motor vehicle disc brake calipers, in particular to a single-piston CBS brake calipers. Background technique [0002] From the perspective of safety, the use of front and rear combined braking system (CBS system) has developed into a necessary trend for all kinds of motorcycles, and the existing types of CBS brake calipers include double-piston structure, three-piston structure and even more The structure of the piston, but even if the above-mentioned CBS brake caliper has a double-piston structure, the caliper will be larger due to the number of pistons. For many scooters with small-sized wheels, it is difficult or even impossible to install. This limits the scope of application of the CBS system. At the same time, due to the number of pistons and the large volume, the material cost of the caliper cannot be reduced, which is not conducive to the market competition of products.
