随着车辆吨位的不断增大,动力转向,特别是液压动力转向,在我国汽车和工程机械中已被广泛应用,一般来说是成功的。但是还存在着转向轮摇摆等问题。这个问题可以说是目前国内车辆存在的一个共性问题。我们先后了解了几种采用液压动力转向的车辆,如SH380、TJ360、CA390、74式轮胎推土机,都出现过转向轮摇动现象,以74式轮胎推土机最为严重。但也有未出现此种现象的,如74式轮胎装载机。
As the tonnage of vehicles continues to increase, power steering, particularly hydraulic power steering, has been widely used in China’s automobiles and construction machinery and has generally been successful. However, there are still problems such as steering wheel sway. This problem can be said to be a common problem with domestic vehicles. We have learned that several types of hydraulic power steering vehicles, such as the SH380, TJ360, CA390, and 74-type tire bulldozers, have experienced the phenomenon of shaking the steering wheel. The 74-type tire bulldozer is the most serious. However, there have been no such phenomena, such as the 74 tire loader.
