AI Technical Summary
Technical Problem
The internal stress caused by thermal expansion and contraction during braking in existing commercial vehicle brake discs affects their service life.
Method used
It adopts a structure that combines the annular connecting plate with the plate body through metallurgy. It is fixedly connected by columns to form an air duct. The flange indirectly connects to the plate body. The connecting claws are integrally cast. The columns and connecting claws enhance the structural stability and heat dissipation effect.
Benefits of technology
It improves the structural strength and service life of the brake disc, avoids cracks caused by internal stress, enhances heat dissipation performance, and extends the service life of the brake disc.

Abstract
本发明公开了一种制动盘，包括：盘体和连接盘，盘体包括两个间隔设置的盘面，连接盘为环状圆盘构型并与两个盘面互相朝向的一侧均通过冶金结合连接，两个盘面之间通过多个立柱固定连接；法兰，固定连接于连接盘的内圈；连接爪，浇注成型于连接盘圆周方向上的花瓣式熔合板外壁，连接爪与盘体一体浇注成型。本发明通过设置连接盘以从盘体上两个盘面的对称面处对两个盘面进行连接，而法兰则与连接盘固定，以使得两个盘面均能够独立朝外形变而避免单侧内部应力过大，同时通过立柱连接提供了多组风道以供散热，且浇注成型连接爪与花瓣式的熔合板连接为一体结构以提升结构强度，进而提升制动盘的使用寿命。本发明还公开了一种制动盘的制作方法。
