Problems solved by technology

However, the thermal conductivity is poor. The brake disc made of it, the heat generated during braking cannot be quickly transmitted, resulting in a higher temperature on the braking surface, and the temperature of the matching friction plate will also increase. Affect the braking effect

Embodiment Construction

[0036] Embodiments of the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and therefore are only examples, rather than limiting the protection scope of the present invention.

[0037] Such as figure 1 As shown, a new brake disc includes a brake friction part 1 made of gray cast iron and a hub connection part 2 made of nodular cast iron. Both the brake friction part 1 and the hub connection part 2 are ring-shaped, and the brake friction part 1 It is socketed and fixed on the outer peripheral side wall of the hub connection, and the brake friction part 1 and the hub connection part 2 are fixedly connected by solid-liquid fusion.

[0038] Preferably, as figure 2 As shown, there are a plurality of positioning protrusions 4 on the outer peripheral side wall of the hub connecting part 2, and...

Abstract

The invention relates to the field of vehicle brake components and specifically relates to a novel brake disc. The brake disc comprises a brake friction portion made of gray cast iron and a hub jointportion made of ductile iron; the brake friction portion and the hub joint portion are both annular; the brake friction portion sleeves and is fixed to a peripheral side wall of the hub joint portion.The invention has simple structure and excellent heat dissipation performance and structural strength.

Description

technical field [0001] The invention relates to the field of vehicle brake components, in particular to a novel brake disc. Background technique [0002] Existing automobile brake discs are made of a single cast iron material, usually gray cast iron or nodular cast iron. [0003] Gray cast iron has good thermal conductivity, but its strength is relatively low. The frequency of the brake disc made of it is not much different from that of the entire brake assembly, and it is prone to defects such as car brake vibration, abnormal noise, and material thermal fatigue. Under the condition of frequent braking of the car, disc cracking may also occur. Its good thermal conductivity can make the braking surface dissipate heat quickly, but the heat will also be quickly transferred to the internal ABS anti-lock braking system along the disc body, causing the ABS to be heated and deformed, affecting the signal received by the sensor, and making the ABS work invalid. Affects braking saf...
