The invention discloses a central drum brake, including core shaft, drum barrel, rocker arm, rotating drive shaft, drive shaft, shaft, cone cone brake brake. The rotating drive shaft, the transmission conical shaft and the conical shaft of the brake are arranged on the core axis in turn. The reposition spring of the transmission conical shaft is set between the conical shaft of the transmission and the conical shaft of the brake. The brake disc is arranged between the driving conical shaft and the conical shaft of the brake. The flower drum barrel through the bearing and the rotating drive shaft assembly, a rotating drive shaft arranged on a core shaft through the bearing, the rocker arm is fixed on the rotating drive shaft, rotary drive transmission end and end face of the shaft within the cone axis relative to the corresponding set of circular groove of the same slope, the slope of the circular groove for placing the ball. The brake line is driven by the rotating drive shaft driven by the rocker arm, and with the circular arc groove and steel ball of the slope to drive the conical axis of the brake to drive the brake disc to expand and achieve the brake. The invention is used for non motor vehicle brake, which has the advantages of simple structure, convenient manufacture, flexible and reliable braking.

一种中心鼓刹
本专利技术涉及一种非机动车刹车装置,具体说是一种中心鼓刹。
技术介绍
现有非机动车刹车装置中,有一种脚刹采用鼓刹方式,制动效果好,维护成本低。中国技术专利《自行车脚刹器》(专利号ZL200520102878.2)公开了一种脚刹,其基本结构:包括轴芯、飞轮片、中管以及刹车组件,飞轮片通过链条与脚踏链轮连接,中管通过轴承安装在轴芯的中部,刹车组件包括驱动螺旋、离合圆锥、刹车圆锥、刹车片。驱动螺旋与飞轮片固定连接,驱动螺旋右侧通过轴承安装在轴芯上,驱动螺旋左侧为导向螺纹段,离合圆锥安装在导向螺纹段上,中管的内孔斜面处与离合圆锥右端斜面配合。刹车圆锥固定安装在中管左侧的轴芯上;刹车圆锥与离合圆锥之间通过压紧弹簧连接;刹车圆锥与刹车片的配合处、离合圆锥与刹车片配合处设有斜度。该脚刹工作原理:当脚刹器固定在自行车后轮上后,使用者正常骑行时,由链条给飞轮片向前施力,往前带动飞轮片,飞轮片再带动驱动螺旋,在导向螺纹的作用下,离合圆锥向右运动,使离合圆锥右端与中管内孔内斜面紧密接触,产生驱动,从而带动壳体向前转动;需要刹车时倒转链条,给飞轮反向施力,带动驱动螺旋,由驱 ...
