The invention relates to the technical field of suspension systems, and discloses a forklift self-adaptive suspension and damping device which comprises an axle, an axle penetrates through the middle of the axle and is rotationally connected with the axle, and wheels are installed at one end of the axle; the suspension structure is arranged at the top of the axle and comprises a first damping spring, a hydraulic cylinder and a three-way pipe, the hydraulic cylinder is arranged at the top of the axle, a second damping spring is installed at the top of the hydraulic cylinder, and the outer wall of the hydraulic cylinder is sleeved with the first damping spring; according to the device, a first damping spring and a second damping spring are used for damping together, the damping capacity is enhanced, when a piston extrudes a touch rod, the touch rod touches a switch to enable a hydraulic pump to work, at the moment, a through hole corresponds to an upper pipeline of a three-way pipe, the hydraulic pump pumps hydraulic oil into a hydraulic cylinder through the three-way pipe, and a piston rod drives the first damping spring to stretch; the length is increased, the compressible distance is increased, and the situation that the vehicle driving stability and the comfort of a driver are affected due to excessive compression of a suspension system is avoided.
本发明涉及悬挂系统技术领域,公开了一种叉车自适应悬挂与减震装置,包括:车桥,车桥中间贯穿并转动连接有车轴,车轴一端安装有车轮;悬挂结构,悬挂结构设置于车桥顶部,悬挂结构包括减震弹簧一、液压缸和三通管,车桥顶部设置有液压缸,液压缸顶部安装有减震弹簧二,液压缸外壁套设有减震弹簧一;本发明中,通过减震弹簧一与减震弹簧二一起减震,增强减震能力,当活塞挤压触碰杆时,触碰杆触碰开关使液压泵工作,此时通孔与三通管的上管道相对应,液压泵将液压油通过三通管泵入液压缸内,使活塞杆带动减震弹簧一拉伸,使其长度增加,可压缩距离增加,避免悬挂系统过度压缩影响车辆行驶稳定性以及驾驶员的舒适性。
