The invention discloses a negative pressure damping return hydraulic oil cylinder of a motorcycle. The drum brake hydraulic braking structure is composed of a return spring, an O-shaped piston sealing ring, a pressure oil inlet, a tension bar, an O-shaped sealing ring, a hydraulic oil cylinder, a cavity for preventing the tension bar from being pulled back, a pressure piston, a back sealing plug and a medium storage tank. When brake operation is adopted, external hydraulic oil enters the hydraulic oil cylinder through the pressure oil inlet under the action of an external pressure pump, so that the pressure piston is pushed to move leftwards, at the moment, the pressure piston drives the tension bar to move leftwards, the outer end of the tension bar is in flexible connection with the corresponding brake arm, and the tension bar drives the brake arm to rotate through tension. The brake arms are connected with the corresponding brake shafts, and the brake arms drive the brake shafts to rotate, so that braking of the motorcycle is achieved. Potential safety hazards of easy breakage and insufficient tension of the steel cable are changed.
本发明公开了一种摩托车负压阻尼回位液压油缸;该鼓刹液压制动结构的组成有回位弹簧、O型活塞密封圈、压力油进口、拉力杆、O型密封圈、液压油缸、阻止拉力杆回拉腔、压力活塞、回封塞、介质储存罐;当采取刹车制动的操作时,外部的液压油在外部的压力泵的作用下经压力油进口进入到液压油缸内,由此推动压力活塞向左运动,此时压力活塞带动拉力杆向左运动,拉力杆的外端和对应的刹车臂软连接,拉力杆通过拉力带动刹车臂转动,刹车臂与对应的刹车轴连接,由刹车臂带动刹车轴转动,实现摩托车刹车;改变钢索易断和拉力不足的安全隐患。
