The invention discloses a tractor drive axle suspension system and a tractor. The system comprises two suspension assemblies arranged at the two ends of a drive axle respectively, any suspension assembly comprises a swing arm rotationally connected with the drive axle and a connecting rod; the first end of the swing arm is hinged to a tractor frame, and the second end of the swing arm is hinged toa damping assembly used for being connected with the tractor frame; the first end of the connecting rod is hinged to the drive axle, and the second end of the connecting rod is hinged to the frame. By applying the system, the swing arm is rotationally connected with the drive axle, the moment of inertia of the drive axle is converted into rotation of the swing arm and the drive axle during braking, the problem of forward impact of the drive axle in the prior art under the inertia effect is solved, and the driving experience is improved; the connecting rod hinged to the frame is arranged to bear radial loads and axial loads, stability is improved, and vibration and movement of the vehicle in all directions are reduced; a spherical bearing bush, an end cover and a knuckle bearing are matched, so that hub swing angle strokes on the two sides of the drive axle are different, two wheels are relatively independent, and impact on a vehicle is reduced.

    本发明公开了一种牵引车驱动桥悬挂系统及牵引车,包括分别设于驱动桥两端的两组悬挂组件,任一悬挂组件包括:与驱动桥转动连接的摆臂,摆臂的第一端与车架铰接,摆臂的第二端铰接有用以与车架连接的减震组件;连杆,连杆的第一端与驱动桥铰接,连杆的第二端与车架铰接。应用该装置,摆臂和驱动桥转动连接,当刹车时将驱动桥的转动惯量转化为摆臂和驱动桥的转动,解决惯性作用下现有技术中驱动桥向前冲击的问题,提高驾驶体验;设置与车架铰接的连杆,以承受径向载荷和轴向载荷,提高稳定性,降低车辆各方向的震动和移动;球形轴瓦和端盖、以及关节轴承的配合,使得驱动桥两侧的轮毂摆角行程不同,两轮相对独立,降低对车辆的冲击。
