Abstract

The invention provides a special-shaped helical compression spring and a back disc type brake caliper assembly with the same, belonging to the technical field of special-shaped helical compression springs. The invention has the first aim of providing the special-shaped helical compression spring, wherein a steel wire of the spring is composed of continuous Z shapes arranged in parallel and linearly connected end to end to define a ring shape; and the upper edge and the lower edge of each Z shape respectively forms a helical angle alpha larger than 0 DEG and smaller than 90 DEC with a beveled edge. The invention has the second aim of providing a back disc type brake caliper assembly with the spring, and compared with a common cylindrical helical compression spring, the special-shaped helical compression spring can ensure that the axial size of the caliper assembly is shortened by 8-10mm. The special-shaped helical compression spring provided by the invention is compact in structure and stronger in axial force; parameters of the spring are still easy to adjust when the layout space of the spring is smaller; and the special-shaped helical compression spring is simple in structure, reliable in principle, light in weight, low in cost and particularly suitable for being arranged in a part with a smaller space.

Description

technical field [0001] The invention relates to a spring, in particular to a special-shaped helical compression spring. Background technique [0002] The application of helical compression springs in automobile and mechanical design is very common, but in practical applications, the spring layout space is often small due to the compact overall structure design. At this time, it is difficult for ordinary helical compression springs to meet its design requirements. [0003] Therefore, we need a spring with a compact structure, which has a strong axial force and is still easy to adjust the parameters of the spring when the spring arrangement space is small. Contents of the invention [0004] In view of the above problems, the present invention provides a special-shaped helical compression spring and a rear disc brake caliper assembly using the spring. The spring has a compact structure, has a strong axial force, and is still easy to adjust when the spring layout space is smal...
