The engineering truck bogie comprises a framework, a wheel pair, an axle box body, a lower wedge seat and a macromolecule wearing plate, an upper wedge seat is arranged on the framework, the axle box body comprises a main body part and an extension part, the wheel pair is rotatably sleeved with the main body part, the extension part is connected to the main body part, and an elastic component is arranged between the lower wedge seat and the extension part. Under the action of the elastic component, the high-molecular wearing plate is arranged on the lower tapered wedge seat, and the high-molecular wearing plate is in frictional contact with the main body part. The high-molecular wearing plate is arranged on the lower tapered wedge seat, so that when the bogie runs at a high speed, the high-molecular wearing plate and the main body part can move relative to each other and rub each other to generate relative motion resistance, the vibration amplitude between the lower tapered wedge seat and the axle box body is reduced, the vertical vibration of the bogie is reduced, and the service life of the bogie is prolonged. And the walking stability and the riding comfort of the frame can be improved.

    本申请提供一种工程车转向架,包括构架、轮对、轴箱体、下部斜楔座和高分子磨耗板,构架上设置有上部斜楔座,轴箱体包括主体部和延伸部,主体部可转动地套设于轮对,延伸部连接于主体部,下部斜楔座和延伸部之间设置有弹性部件,并在弹性部件的作用下,抵顶于上部斜楔座,高分子磨耗板设置于下部斜楔座,且高分子磨耗板与主体部摩擦接触。通过在下部斜楔座上设置高分子磨耗板,在转向架高速运行时,高分子磨耗板与主体部之间会相对运动,相互摩擦,产生了相对运动阻力,降低了下部斜楔座与轴箱体之间振动幅度,降低了转向架垂向上的振动,有利于提高车架行走的稳定性与乘坐的舒适度。
