Abstract

The invention discloses an anti-cracking brake drum and a manufacturing method thereof. The anti-cracking brake drum comprises a brake drum body. The brake drum body comprises a top face and a cylindrical face vertically extending downward in the circumferential direction of the top face. A plurality of thread-shaped spiral bars are arranged on the inner wall face of the cylindrical face. A connecting bar is arranged between every two adjacent spiral bars. The spiral bars at the starting point and the end point of the inner wall face of the cylindrical face are linear annular sections. The spiral bars are combined on the cylindrical face of the brake drum in a pouring mode, and the spiral bars of the brake drum and the cylindrical face of the brake drum are an integrally-formed part, so that the spiral bars and the cylindrical face do not fall off due to thermal expansion and contraction, the stability property of the brake drum is guaranteed, and the brake drum is prevented from problems such as cracking.

Description

technical field [0001] The invention relates to the technical field of brake drums, in particular to a crack-resistant brake drum and a manufacturing method thereof. Background technique [0002] The brake drum is one of the main parts of the brake system in the driving system of the car. There are brake shoes installed in the brake drum. For action, the brake drum is an open structure at one end. During braking, the brake shoe is easy to crack the brake drum, resulting in brake failure and making the safety of the car unable to be guaranteed. In order to prevent the brake drum from cracking, some A circle is press-fitted into the outer circle of the drum opening to tighten the brake drum. This method is because the brake drum body and the circle are an independent whole, and the brake drum expands with heat and contracts with cold. The circle comes off easily. Contents of the invention [0003] The purpose of the present invention is to propose a brake drum with high te...
