工程机械中的小型装载机、叉车、翻斗车等,由于前端装有工作装置,也为了满足使用方面的要求,它们的转向机构多采用后轮转向,其行驶速度也比运输车辆要低。故此有关转向机构的稳定性,也就没有引起足够的重视。行驶稳定性不好,迫使驾驶员只好降速行驶,其驾驶操作性能较差,其中由于“自动校直”效果不好,是其主要原因。在同样车速、路面条件 Small loaders, forklifts, dumpers and the like used in construction machinery are also equipped with working devices at the front end and are also used in order to meet their requirements for use. Their steering mechanisms use rear wheel steering, and their traveling speed is lower than that of transport vehicles. Therefore, the stability of the steering mechanism, it also did not cause enough attention. Driving stability is not good, forcing the driver had to slow down, poor driving performance, which due to “automatic alignment” effect is not good, is the main reason. At the same speed, pavement conditions
