目前Ｒ１７０电动轮汽车悬挂系统使用较普及的减振介质是惰性气体和硅油。硅油的使用，使得悬挂系统的能量吸收能力大大提高，从而改善汽车的运行状况，提高了车辆的使用寿命。随着硅油悬挂的大量使用，也暴露了它的一些缺点，如硅油的压缩比小，造成悬挂的刚度较大，且受温差?
R170 electric car suspension system is currently more popular damping medium is inert gas and silicone oil. The use of silicone oil, making the suspension system greatly enhance the energy absorption capacity, thereby improving the car’s operating conditions and improve vehicle life. With the heavy use of silicone suspension, but also exposed some of its shortcomings, such as the compression ratio of silicone oil is small, resulting in greater suspension stiffness, and temperature difference?
