The invention discloses a damping and shock absorption integrated wheelbarrow which comprises a motor wheel. The frame is vertically and movably connected relative to the motor wheel, and pedals are arranged on the two sides of the frame respectively; the single-cylinder damping shock absorber is connected between the motor wheel and the frame and is used for providing shock absorption and damping for the up-down movement of the frame; the single-barrel damping shock absorber comprises a cylinder barrel, a piston rod, an oil piston and a floating plug, the oil piston and the floating plug are sequentially arranged in the cylinder barrel in a sliding mode so that a cavity in the cylinder barrel can be sequentially divided into a first oil cavity, a second oil cavity and an air cavity, and the piston rod penetrates into the first oil cavity from one end of the cylinder barrel and is connected with the oil piston. A damping valve used for communicating the first oil cavity with the second oil cavity is arranged on the piston rod and/or the oil piston. According to the damping and shock absorption integrated wheelbarrow, the damping function and the shock absorption function are integrated on the single-cylinder damping shock absorber, and the damping and shock absorption integrated wheelbarrow is simple in structure and small in overall occupied space.
本发明公开了一种阻尼减震一体化的独轮车,包括:电机轮;车架,相对电机轮上下活动连接,车架的两侧分别设置有脚踏板;单筒阻尼减震器,连接于电机轮和车架之间,为车架的上下活动提供减震和阻尼;其中,单筒阻尼减震器包括缸筒、活塞杆、油活塞以及浮游塞,油活塞和浮游塞依次滑动设置于缸筒的内部,以将缸筒内部的空腔依次分隔为第一油腔、第二油腔和气腔,活塞杆由缸筒的一端穿入第一油腔并与油活塞相连接,活塞杆和/或油活塞上设置有用于导通第一油腔和第二油腔的阻尼阀。本发明提供一种阻尼减震一体化的独轮车,将阻尼功能和减震功能集成到单筒阻尼减震器上,其结构简单,整体占用空间小。
