The invention relates to a triangular crawler wheel and an engineering vehicle. The triangular crawler wheel comprises a crawler, a driving wheel which is arranged on the inner side of the crawler belt and is in transmission fit with the crawler belt, a supporting frame which is arranged on the inner side of the crawler, and connected with the driving wheel and used for bearing the driving wheel,and a load-carrying wheel assembly which is arranged at the inner side of crawler; and the load-carrying wheel assembly comprises a load-carrying wheel, a swing frame, a fixing base and a fixing pinshaft; the load-carrying wheel is in transmission fit with the crawler at the bottom; the swing frame is installed on the supporting frame and can swing around a first axis; the first axis is parallelto the axis of the load-carrying wheel; the fixing base is installed on the swing frame and can rotate around a second axis; the second axis extends in the horizontal direction and is perpendicular to the first axis; the fixing pin shaft extends in a vertical direction and is rotatably installed on the fixing base; and the load-carrying wheel is connected with the fixing pin shaft so that the load-carrying wheel can swing around a third axis extending in the vertical direction. The load-carrying wheel of the triangular crawler wheel can swing in a multi-degree-of-freedom mode, and the capacity of the triangular crawler wheel for adapting to complex terrains is improved.

    本发明涉及一种三角履带轮和工程车辆,三角履带轮包括:履带;驱动轮,设在履带的内侧,并与履带传动配合;支撑架,设在履带的内侧并与驱动轮连接,用于承载驱动轮;负重轮组件,设在履带的内侧,负重轮组件包括负重轮、摆动架、固定座和固定销轴,负重轮与处于底部的履带传动配合,摆动架安装在支撑架上并可绕第一轴线摆动,第一轴线与负重轮的轴线平行,固定座安装在摆动架上并可绕第二轴线转动,第二轴线沿水平方向延伸并垂直于第一轴线,固定销轴沿竖直方向延伸并可转动地安装在固定座上,负重轮与固定销轴连接,以使负重轮绕沿竖直方向延伸的第三轴线摆动。三角履带轮的负重轮可多自由度地摆动,提高了三角履带轮适应复杂地形的能力。
