The invention provides a pull rod type suspension which comprises a connecting framework connected with an auxiliary frame and provided with a containing groove, one end of a pull rod assembly is provided with an inserting part inserted into the containing groove, the other end of the pull rod assembly is connected with a power assembly, and the inserting part and the bottom wall of the containing groove are arranged at an interval. A rubber main spring is connected between the connecting framework and the pull rod assembly, and the pull rod type suspension further comprises a limiting structure for limiting relative displacement between the pull rod assembly and the connecting framework in the length direction and/or the width direction of the vehicle. The pull rod type suspension can well buffer impact force in the length direction or the width direction of a vehicle when the vehicle accelerates, decelerates and brakes or meets an uneven road surface, in addition, by arranging a limiting structure, displacement between the pull rod assembly and the connecting framework can be limited, the deformation degree of the rubber main spring can be improved, and the service life of the pull rod type suspension is prolonged. And the service life of the rubber main spring is prolonged, so that the service life of the pull rod type suspension is prolonged.

    本发明提供了一种拉杆式悬置,其包括与副车架相连并具有容置槽的连接骨架,拉杆总成一端设有插置于容置槽中的插置部,另一端与动力总成连接,且插置部和容置槽的底壁间距设置;于连接骨架和拉杆总成之间连接有橡胶主簧,且拉杆式悬置还包括于车辆长度方向和/或车辆宽度方向上限制拉杆总成和连接骨架间相对位移的限位结构。本发明所述的拉杆式悬置,可在车辆加速、减速、制动或遇不平整路面时,于车辆长度方向或车辆宽度方向较好的缓冲冲击力,此外,通过设置限位结构,可对拉杆总成和连接骨架间位移进行限制,而可改善橡胶主簧变形程度,延长橡胶主簧使用寿命,进而延长拉杆式悬置使用寿命。
