Ring embedded type flexible automobile brake drum

Abstract

The invention relates to a circle-inlaid flexible vehicle brake drum and belongs to the field of vehicle parts. The brake drum is characterized in that at least a groove is formed on the outer wall of the drum body of the vehicle brake drum; at least a hoop cable is circle-inlaid in each groove; the hoop cable is ring-shaped and tightly inlaid and sleeved in the groove; and each hoop cable is formed by collecting / stranding a plurality of flexible wire ropes / steel cables or flexible alloy ropes / cables. Each hoop cable is fixedly connected with the cylindrical or conical drum body at intervals of arc distance through the welding method. The hoop cable, the welding joint and the groove of the drum body keep on a plane. The brake drum has the advantages of simple structure, safety, reliability and convenient use. Under the condition of same materials, the service life of the vehicle brake drum can be prolonged by one third. The circle-inlaid flexible vehicle brake drum is a novel product with wide market prospect.

Description

Technical field: [0001] The invention relates to a ring-embedded flexible automobile brake drum, which belongs to the field of automobile parts. Background technique: [0002] Usually automobile brake drums are processed from pure castings. The overall shape of the automobile brake drum is like a basin, wherein one end of the automobile brake drum is open, and the other end is the brake drum bottom. The brake drum bottom is directly connected with the cylindrical or conical brake drum body to form a whole. Since one end of the automobile brake drum made of pure castings has an open structure, in the actual driving process of the vehicle, the frequency of use of the brake drum is high, and the open end of the drum body is easily crushed and burst, resulting in a reduction in the service life of the automobile brake drum. affect the driving of the vehicle. Make automobile brake drum as alloy material such as adopting steel, although be not easy to be crushed by pressure, be ...

AI Technical Summary

Problems solved by technology

Since one end of the automobile brake drum made of pure castings has an open structure, in the actual driving process of the vehicle, the frequency of use of the brake drum is high, and the open end of the drum body is easily crushed and burst, resulting in a reduction in the service life of the automobile brake drum. Affect the driving of vehicles

For example, steel and other alloy materials are used to make automobile brake drums. Although it is not easy to be crushed and cracked, the cost is high and the price is high, which is unbearable for car owners and drivers.

If the method of increasing the wall thickness of the brake drum casting is used, although it can play a certain role in preventing cracking, the overall size of the brake drum will become larger, which will affect the installation or even make it impossible to install.
