Embodiment Construction

[0035] It should be noted that, in the case of no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0036] The present invention will be described in detail below with reference to the drawings and in combination with embodiments.

[0037] The present invention provides a method for manufacturing a brake disc of a vehicle, wherein the brake disc includes a main body disc 1 and two friction rings 2, and the friction rings 2 are annular plates attached to the main body disc 1 on both sides of the disk, the manufacturing method includes the following steps:

[0038] S1. Casting two friction rings 2 using cast iron materials;

[0039] S2. Prepare a casting mold and a core mold for the brake disc, the casting mold has a cavity corresponding to the brake disc, fix the core mold and the two friction rings 2 on the Corresponding position in the cavity;

[0040] S3. Casting molten aluminum alloy into the cavity, the...

Abstract

The invention relates to the field of vehicle component processing, and provides a manufacturing method of a vehicle brake disc, wherein the brake disc comprises a body disc and two friction rings, the manufacturing method comprises the following steps of: casting two friction rings by adopting a cast iron material; preparing a casting mold and a core mold, wherein the core mold and the two friction rings are respectively fixed in corresponding positions in a mold cavity; pouring molten aluminum alloy into the cavity to form the brake disc; carrying out heat treatment on the brake disc, wherein the inner surface of the friction rings jointed with the body disc is a rough surface, so that the body disc and the friction rings can be embedded into each other. The production method of the invention can be used for manufacturing an aluminum alloy body disk and a cast iron friction ring, and can fully give play to the wear resistance, high friction and high temperature resistance of the castiron by the combination of two materials of cast iron and aluminum alloy, meanwhile, the aluminum alloy material can fully reduce the overall mass of the brake disc, so that the mass of the spring isreduced, and the operation stability of the vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle component processing, in particular to a method for manufacturing a brake disc of a vehicle. Background technique [0002] When designing a vehicle, in order to improve the handling stability of the vehicle, it is often necessary to control (i.e. reduce) the unsprung mass of the vehicle. The so-called "unsprung mass" refers to the weight not supported by the vehicle suspension system: tires, wheels, brakes. The traditional brake disc made of cast iron occupies a large proportion of the unsprung mass, so reducing the mass of the brake disc can effectively reduce the unsprung mass, thereby improving the handling stability of the vehicle while reducing the vehicle weight. [0003] At present, automobile brake discs are generally made of cast iron, such as HT200, HT300 or forged steel materials, with a density of about 7.3-7.8g / cm 3 , the material density is relatively high, and the overall weight of...
