The invention provides a pull rod type suspension and a vehicle. The pull rod type suspension comprises a framework, a pull rod support and a rubber main spring, and a limiting structure is arranged between the framework and the pull rod support; one end of the framework is provided with an opening, one end of the pull rod support is provided with an inserting part, the inserting part is connected with the framework through a rubber main spring, the limiting structure comprises at least two limiting units, each limiting unit comprises a limiting arm and a limiting groove, the limiting arms are inserted in the limiting grooves, the limiting arms are coated with elastic bodies, and/or the limiting grooves are internally coated with elastic bodies. According to the pull rod type suspension, impact force and load generated by the power assembly can be repeatedly transmitted and buffered through the two limiting units and the rubber main spring till being consumed, the rubber main spring is prevented from losing efficacy due to excessive stretching, the fatigue durability of the rubber main spring can be improved, meanwhile, the offset of the power assembly is reduced, and the service life of the power assembly is prolonged. And the torsion resistance is better.
本发明提供了一种拉杆式悬置及车辆,所述拉杆式悬置包括骨架、拉杆支架和橡胶主簧,并在骨架与拉杆支架之间设有限位结构;骨架的一端设有开口,拉杆支架的一端具有插装部,插装部通过橡胶主簧与骨架相连,限位结构包括至少两个限位单元,各限位单元包括限位臂,以及限位槽,限位臂插设于限位槽内,在限位臂上包覆有弹性体,和/或在限位槽内覆设有弹性体。本发明所述的拉杆式悬置,动力总成产生的冲击力和载荷可通过两个限位单元和橡胶主簧反复进行传递缓冲直至消耗,利于防止橡胶主簧因过度拉伸而失效,而可提升橡胶主簧的疲劳耐久性,同时,还利于减少动力总成的偏移量,而具有较好的抗扭性能。
