The invention provides a double-wishbone suspension structure and a mining transport vehicle. The double-wishbone suspension structure comprises a wheel bearing shaft assembly, an upper wishbone beam, a lower wishbone beam and a hydro-pneumatic suspension cylinder. The upper and lower ends of the wheel bearing shaft assembly are respectively in spherical hinge connection with one end of the upper cross arm beam and one end of the lower cross arm beam; the other end of the upper cross arm beam and the other end of the lower cross arm beam are respectively hinged with a frame of the vehicle; the lower cross arm beam is positioned below the upper cross arm beam; two ends of the hydro-pneumatic suspension cylinder are respectively connected with the upper cross arm beam and the frame; wherein the connecting position of the hydro-pneumatic suspension cylinder and the frame is located above the connecting position of the upper cross arm beam and the frame; the central axis between the upper end and the lower end of the wheel bearing shaft assembly serves as the main axis, and the centroid of the joint of the hydro-pneumatic suspension cylinder and the upper cross arm beam and the main axis are arranged at intervals. The damping effect of the hydro-pneumatic suspension cylinder on the upper cross arm beam is guaranteed, tire abrasion is effectively reduced, and the service life of tires is prolonged.
本发明提供了一种双横臂悬架结构及矿用运输车,双横臂悬架结构包括:车轮承载轴组件、上横臂梁、下横臂梁和油气悬挂缸;车轮承载轴组件上下两端分别与上横臂梁的一端、下横臂梁的一端球铰连接;上横臂梁的另一端、下横臂梁的另一端分别与车辆的车架铰接;下横臂梁位于上横臂梁的下方;油气悬挂缸的两端分别与上横臂梁、车架连接;其中,油气悬挂缸与车架的连接位置位于上横臂梁与车架连接位置的上方;以车轮承载轴组件上端和下端之间的中轴线为主轴线,油气悬挂缸和上横臂梁的连接处的形心与主轴线间隔设置。本发明保证了油气悬挂缸对于上横臂梁的缓震效果,有效降低了轮胎磨损,延长了轮胎的使用寿命。
