工程车用转向架及工程车

Abstract

本实用新型提供一种工程车用转向架及工程车。工程车用转向架包括H型焊结构架、一系悬挂机构、二系悬挂机构和牵引装置;一系悬挂机构包括四个转臂式轴箱、两个轮对、四个螺旋弹簧和四个垂向减振器,转臂式轴箱通过转臂橡胶节点铰接在H型焊结构架上;二系悬挂机构包括两个空气弹簧、两个高度控制阀、差压阀、两个横向减振器和两个抗蛇行减振器;牵引装置包括牵引销、牵引梁和两个牵引拉杆,牵引销可转动的连接在牵引梁的中部,牵引梁的端部与H型焊结构架之间设置有牵引拉杆,牵引梁和两个牵引拉杆形成Z字形结构,牵引梁的端部与对应的横向减振器连接。实现提高工程车用转向架高速运行的稳定性和可靠性。
The utility model provides an engineering vehicle and a bogie for the same. The bogie for the engineering vehicle comprises an H-shaped weld framework, a primary suspension mechanism, a secondary suspension mechanism and a traction device. The primary suspension mechanism comprises four rocker arm type axle boxes, two wheel pairs, four spiral springs and four vertical shock absorbers, and the rocker arm type axle boxes are hinged onto the H-shaped weld framework by rocker arm rubber joints; the secondary suspension mechanism comprises two air springs, two height control valves, a differential valve, two transverse shock absorbers and two anti-snaking shock absorbers; the traction device comprises a traction pin, a traction beam and two traction draw bars, the traction pin is rotatably connected to the middle of the traction beam, the traction draw bars are arranged among the ends of the traction beam and the H-shaped weld framework, Z-shaped structures are formed by the traction beam and the two traction draw bars, and the ends of the traction beam are connected with the corresponding transverse shock absorbers. The engineering vehicle and the bogie for the engineering vehicle have the advantage that the high-speed running stability and reliability of the bogie for the engineering vehicle can be improved.
