The invention relates to a lateral stabilizer bar assembly with variable roll stiffness and a vehicle. The lateral stabilizer bar assembly comprises a lateral stabilizer bar, a stabilizer bar hanging rod, an additional rocker arm, a pawl and a separation mechanism. The bottom of the stabilizer bar suspender is rotationally connected to one end of the transverse stabilizer bar; one end of the additional rocker arm is rotatably connected to the top of the stabilizer bar suspender, the additional rocker arm is provided with a mounting area used for being rotatably connected to a frame, and the additional rocker arm is further provided with a ratchet tooth; the pawl is located above the additional rocker arm, one end of the pawl is rotationally connected to a frame, and the other end of the pawl is matched with the ratchet teeth; the separating mechanism is used for driving the pawl to leave from the ratchet teeth. According to the transverse stabilizer bar assembly, the problems that in the prior art, due to the fact that a certain idle stroke is left in a transverse stabilizer bar assembly, the roll angle of a vehicle is larger than that of a traditional stabilizer bar under the condition that lateral force is the same, the overall anti-roll performance of the vehicle is reduced, and for a commercial vehicle with the ultrahigh mass center or the large mass, the overall anti-roll performance of the vehicle is poor can be solved. And a large performance risk exists.

    本申请涉及一种变侧倾刚度的横向稳定杆总成及车辆,其包括横向稳定杆、稳定杆吊杆、附加摇臂、棘爪和分离机构;稳定杆吊杆的底部转动连接于横向稳定杆的一端;附加摇臂的一端转动连接于稳定杆吊杆的顶部,附加摇臂上设有用于转动连接于车架上的安装区,附加摇臂上还设有一个棘轮齿;棘爪位于附加摇臂上方,且其一端用于转动连接于车架上,另一端与棘轮齿相适配;分离机构用于驱使棘爪从棘轮齿中离开。本申请可以解决相关技术中由于横向稳定杆总成中留下了一定空行程,在侧向力相同的情况下,车辆的侧倾角相比传统稳定杆而言会更大,导致车辆的整体抗侧倾性能降低,对于超高质心或质量较大的商用车而言,存在较大的性能风险的问题。
