The invention provides a sectional type transverse plate spring trailing arm independent rear suspension which is characterized in that the front end and the rear end of a first trailing arm and the front end and the rear end of a second trailing arm are hinged to a frame respectively, and the outer side of the first trailing arm and the outer side of the second trailing arm are fixedly connected with a first rear wheel and a second rear wheel respectively; the connecting end of the first sectional type transverse plate spring is hinged to the inner side of the end, close to the vehicle tail, of the first trailing arm, the connecting end of the second sectional type transverse plate spring is hinged to the inner side of the end, close to the vehicle tail, of the second trailing arm, and a cantilever of the first sectional type transverse plate spring is provided with a first inner side plate spring fixing base and a first outer side plate spring fixing base. A second outer side plate spring fixing base and a second inner side plate spring fixing base are arranged on a cantilever of the second sectional type transverse plate spring, and the first inner side plate spring fixing base, the first outer side plate spring fixing base, the second inner side plate spring fixing base and the second outer side plate spring fixing base are all fixedly connected with a vehicle frame. The space utilization rate of the lower chassis can be increased, and the rigidity adjustment convenience of the elastic element is improved.

    本发明提供了一种分段式横向板簧拖曳臂独立后悬架,包括:第一拖曳臂和第二拖曳臂的前后两端分别与车架铰接,第一拖曳臂和第二拖曳臂的外侧分别与第一后轮和第二后轮固定连接;第一分段式横向板簧的连接端与第一拖曳臂靠近车尾的一端内侧铰接,第二分段式横向板簧的连接端与第二拖曳臂靠近车尾的一端内侧铰接,第一分段式横向板簧的悬臂上设置第一内侧板簧固定座和第一外侧板簧固定座,第二分段式横向板簧的悬臂上设置第二外侧板簧固定座和第二内侧板簧固定座,所述第一内侧板簧固定座、第一外侧板簧固定座、第二内侧板簧固定座和第二外侧板簧固定座均与车架固定连接。本发明可提升下底盘空间利用率,提高弹性元件刚度调节的便捷性。
