An axle assembly provided with a long-service-life light-weight carbon ceramic brake disc comprises an installation head and a friction disc, the installation head and the friction disc are connected through a bolt, a torsion pin is installed at the position of a bolt connecting hole, and a gasket is installed between the bolt and the friction disc face. The friction disc is in a circular ring step shape and comprises an inner circular ring step surface with a low middle part and an outer circular ring step surface with a high outer circumference; a second bolt hole is formed in the step surface of the inner circular ring; ventilation grooves are formed in the step face of the outer circular ring in the radial direction of the interior of the friction disc, small ventilation holes are formed in the surface of the friction disc, the small ventilation holes are distributed in the axial direction of the air grooves, the small ventilation holes penetrate through the surface of the friction disc, and the small ventilation holes are communicated with the ventilation grooves. The integrated friction disc is adopted, so that the unsprung mass is lighter, and the controllability of a vehicle is improved; the heat dissipation performance is more excellent in structural design, the heat dissipation effect of the friction disc is improved, and the stability of a vehicle during braking is improved.
一种装有长寿命轻量化碳陶制动盘的车桥总成,包括安装头和摩擦盘组成,所述安装头和摩擦盘由螺栓连接,在螺栓连接孔位置装扭力销,在螺栓和摩擦盘面之间装有垫片。摩擦盘为圆环台阶状,包括中间低的内圆环台阶面和外圆周高的外圆环台阶面;其中,在内圆环台阶面上设置有第二螺栓孔;在外圆环台阶面上,沿摩擦盘内部的径向方向设置有通风槽,在摩擦盘的表面设置有通风小孔,通风小孔沿风槽轴向方向分布设置,且通风小孔贯通摩擦盘表面,通风小孔与通风槽相通。本发明采用一体式摩擦盘,使簧下质量更轻,提高车辆的操控性;在结构上设计散热性更为优异,提高了摩擦盘的散热效果,车辆在制动时的稳定性。
