The invention discloses a hub driving and braking structure of a suspension type monorail vehicle. The hub driving and braking structure mainly comprises a framework, a hub motor, a hydraulic brake, an axle, a traction rod, a walking wheel and the like. A hub motor driving mode is adopted, a motor is concentrated in a hub, a planet gear speed reducer is adopted, and driving force directly acts on the hub. And meanwhile, the motor rotor is connected with the brake disc, and a hydraulic brake clamp is adopted to provide a brake function. The traction braking system on the left side and the traction braking system on the right side are structurally connected through a shaft bridge, the shaft bridge plays a role in bearing, the shaft bridge and the framework are supported through vertical rubber, and the vertical buffering and vibration reduction effects are provided. The axle and the framework are longitudinally connected through a traction pull rod, and longitudinal force is transmitted. Due to the fact that parts such as couplings are omitted, the purpose of reducing the weight is achieved on the whole, installation is convenient and reliable, vehicle comfort is improved, meanwhile, the axle distance can be reduced, and curve passing capacity is improved.
本发明公开了一种悬挂式单轨车辆轮毂驱动制动结构,主要包括构架、轮毂电机、液压制动器、轴桥、牵引拉杆、走行轮等结构。采用轮毂电机驱动方式,将电机集中在轮毂内部,并采用行星轮减速机,直接将驱动力作用在轮毂上。同时在电机转子与制动盘进行连接,采用液压制动夹钳提供制动功能。左右两侧牵引制动系统结构上通过轴桥进行连接,轴桥起到承载的作用,轴桥与构架采用垂向橡胶支撑,提供垂向的缓冲及减振作用。轴桥与构架的纵向采用牵引拉杆进行连接,传递纵向力。由于少了联轴节等部件,整体上实现减重的目的,安装便捷可靠,提高了车辆舒适性,同时可以减小轴距,提高曲线通过能力。
