The invention discloses an engineering vehicle chassis, and belongs to the technical field of four-wheelers. The device comprises a chassis frame and a connecting bridge, wherein two ends of the chassis frame are fixedly connected with a pair of fixing frames; the connecting bridges are connected to the two ends of the chassis frame correspondingly, and wheels are installed at the two ends of each connecting bridge. A pair of sliding frames are slidably connected into the fixed frame in the length direction of the fixed frame. Rotating arms are connected to the sliding frames, and connecting arms are rotationally connected to one ends of the rotating arms; a buffering tension mechanism is fixedly connected to the middle of the fixing frame, and the two connecting arms are rotationally connected with the buffering tension mechanism; the connecting bridge is fixedly connected with a pair of connecting seats correspondingly connected with the sliding frames, and the connecting seats are connected with the sliding frames in an up-down sliding mode. By arranging the fixed frame, the sliding frame and the buffering tension mechanism, the wheel force on one side is transmitted to the other side, the chassis frame is kept in a nearly horizontal state, and meanwhile, the buffering tension mechanism is matched, so that the good buffering and damping purposes are achieved.

    本发明公开了一种工程车底盘,属于四轮车技术领域。本发明包括底盘架和连接桥,底盘架两端固定连接有一对固定架;连接桥分别连接在底盘架的两端,连接桥的两端均安装有车轮;固定架内沿其长度方向滑动连接有一对滑动架;滑动架上均连接有转动臂,转动臂的一端转动连接有连接臂;固定架中间处固定连接有缓冲拉力机构,两个连接臂均与缓冲拉力机构转动连接;连接桥上固定连接有一对与滑动架对应连接的连接座,连接座与滑动架上下滑动连接。本发明通过设有固定架、滑动架和缓冲拉力机构,一侧车轮力传导至另一侧,底盘架则保持近水平状态,同时配合缓冲拉力机构,起到较好的缓冲减震目的。
