Slotted disc friction plate

The utility model relates to the technical field of friction plates, in particular to a slotted disc type friction plate, which guides and discharges dust and heat generated by brake friction through a damping slot arranged on the upper surface of a friction body, has a good heat dissipation effect and prolongs the service life of the friction plate. The transverse grooves and the longitudinal grooves which are arranged on the upper surface of the friction body in a staggered mode divide the upper surface of the friction body into a plurality of irregular small blocks, so that the inherent frequency of the disc type friction plate is changed, shock absorption and noise reduction are achieved, and meanwhile the phenomenon that the friction body is prone to fracture due to stress concentration is avoided. 本实用新型涉及摩擦片技术领域，特别是涉及一种开槽式盘式摩擦片，通过设置于摩擦体上表面的减震槽将制动摩擦产生的灰尘和热量导向排出，散热效果好，延长了摩擦片的使用寿命；本实用新型的摩擦体上表面交互交错布置的横向槽和纵向槽，将所述摩擦体的上表面分割为多个不规则小块，从而改变盘式摩擦片固有频率，起到减震降噪，同时避免了应力集中造成摩擦体易断裂现象。
