Abstract

本发明公开了矿用自卸车悬挂及载重自适应刚度调节与振动能回收装置，包括油气悬挂载重自适应刚度调节单元、轮胎刚度载重自适应调节单元和振动能回收单元；油气悬挂载重自适应刚度调节装置通过蓄能器的气腔内气体压力和体积的变化实现对所述悬挂油缸在不同工况下活塞平衡位置的调节；所述轮胎刚度调节装置通过轮胎储气油缸的气腔内气体压力和容积的变化实现对车胎在不同工况下进行自适应的刚度调节；振动能回收单元包括空气压缩装置；所述空气压缩装置将油气悬挂活塞杆的往复伸缩移动转化为两换向轴从动齿轮的单向转动，经空气压缩装置输出轴为空压机提供动力产生高压气体，为轮胎刚度自适应调节装置补气，或驱动后续发电装置发电储存。
