The walking vehicle with the multi-gear speed regulation function is provided with a left middle shaft and a right middle shaft which can rotate independently, and the two ends of the two middle shafts are each provided with a pedal device. Two groups of transmission mechanisms are arranged between the two groups of pedal devices and the driving wheel shaft; each transmission mechanism comprises a ratchet wheel fixedly connected to the driving wheel shaft, a rope winding ring hinged to the driving wheel shaft, a fixed pulley arranged above the swing track of the free end of the foot rest lever, a winding rope connected between the rope winding ring and the free end of the foot rest lever through the fixed pulley, and a reset device connected between the rope winding ring and the frame. A speed regulating mechanism is arranged at the free end of the foot rest lever and comprises a sliding rail arranged at the free end of the foot rest lever, a sliding pipe connected to the sliding rail in a sleeving mode and a positioning switch used for positioning the sliding pipe at different gears of the sliding rail. Manual cooperation is not needed during gear shifting, and the gear shifting procedure can be automatically completed only by lightly shifting the shifting rod from the inner side of the sole; the speed regulating device is easy to operate and simple and durable in structure, and particularly, riding resistance cannot be additionally increased.
本申请涉及一种具有多档调速功能的步行车,它设有左右两条可分别单独转动的中轴,在两条中轴两端各设置有一组脚踏装置;在两组脚踏装置与驱动轮轴之间,设有两组传动机构;每组传动机构包括固接在驱动轮轴上的一棘轮、铰接在驱动轮轴上的一卷绳环、设置于脚踏杆自由端摆动轨迹上方处的一定滑轮、经过定滑轮连接于卷绳环与脚踏杆自由端之间的一卷绳、以及连接于卷绳环与车架之间的复位装置;在脚踏杆自由端,设有调速机构,调速机构包括设置在脚踏杆自由端的滑轨、套接在滑轨上的滑管、以及用于将滑管定位在滑轨不同档位处的定位开关;调档时不需要手的配合,只需以脚掌内侧轻拨拨杆,即自动完成调挡工序;本申请中调速装置不仅易于操作,且结构简单耐用,尤其是不会额外增加骑行阻力。
