Embodiment

[0011] Embodiment: A kind of brake disc for automobile, a kind of brake disc for automobile, comprises brake friction part 1, installation part 2, and described installation part 2 is fixedly connected with brake friction part 1, and described brake friction part 1 is made of cast iron The mounting part 2 is made of one of two materials: aluminum alloy and aluminum-magnesium alloy, which can effectively reduce weight and improve heat dissipation performance.

[0012] There is an embedded joint part 3, and the structure of the embedded joint part 3 is: the outer ring of the installation part 2 is fixed with a wedge-shaped protrusion (formed integrally in this example), and the inner ring of the brake friction part 1 is correspondingly provided with a wedge-shaped protrusion that matches the shape of the wedge-shaped protrusion. The wedge-shaped protrusion is inserted into the embedded groove, so that the installation part 2 is fixedly connected to the brake friction part 1. The ...

Abstract

The invention discloses an automotive brake disc, which comprises a brake friction part and an installation part. The installation part is fixedly connected with the brake friction part, the brake friction part is made of cast iron, and the installation part is made of aluminum alloy or aluminum-magnesium alloy. The automotive brake disc has the advantages that the automotive brake disc has light weight, good cooling effects can be achieved, the braking performance can be maintained after long-time braking, and the oil consumption can be reduced effectively.

Description

technical field [0001] The invention relates to a brake device for an automobile, in particular to a brake disc for an automobile. Background technique [0002] Traditional brake pads are made of a single metal. This kind of brake disc has many defects: heavy weight, resulting in high fuel consumption; poor heat dissipation; easy to rust, and long-term braking will overheat due to poor heat dissipation, resulting in brake failure resulting in accidents. [0003] According to the theory of chassis transmission, every 1 kg weight reduction of chassis transmission components is equivalent to a reduction of 20 kg in the body load. Therefore, reducing the weight of the brake disc can effectively reduce fuel consumption. Contents of the invention [0004] In order to overcome the above defects, the present invention provides a brake disc for automobiles, which has light weight and good heat dissipation performance. [0005] The technical solution adopted by the present inventi...
