Abstract
The utility model relates to a braking boss of an automobile, which is composed of a cast steel braking boss main body and is characterized in that the inner wall of the cast steel braking boss main body is provided with a gray cast-iron neck bush. The product overcomes the defect of easy fracture and rupture in the prior art, the service life is long and the safety factor is high.
Description
Technical field:
The utility model relates to a kind of braking automobile hub.
Background technique:
Usually brake hub is to adopt the gray cast iron manufacturing of tensile strength at 200-250Mpa, because the operating mode and the stressed more complicated of brake hub, so the working life of common brake hub is short, generally is 2-6 month, but also existence is easily broken, the shortcoming of easy-rupturing, and safety coefficient is low.
Summary of the invention:
The purpose of this utility model is to provide a kind of braking automobile hub, and this product has overcome that prior art is easily broken, the shortcoming of easy-rupturing, and long service life, safety coefficient height.
The utility model comprises cast steel brake hub main body, it is characterized in that: described cast steel brake hub main body inner wall is provided with the gray cast iron neck bush.
The utility model remarkable advantage is: be more than 3 times of general brake hub working life, and product material intensity height is difficult for breaking, rupturing, and has improved running safety greatly.
