    • To dissipate hydraulic shock created by the bouncing of an implement mounted on a wheeled vehicle, such as a towed tillage implement or the bucket of a vehicle, such as a wheel loader, an electronic control valve, which supplies hydraulic fluid to the hydraulic actuator that raises and lowers the implement, is actively controlled by an electronic controller. As the vehicle with an implement is transported at higher speeds, the implement tends to bounce creating pressure spikes in the hydraulic system that raises and lowers the implement. The pressure spikes are dissipated by actively generating random or cancelling hydraulic pulses in the hydraulic system.
    • 为了消除由安装在轮式车辆上的工具的弹跳引起的液压冲击,例如拖曳耕耘机器或诸如轮式装载机的车辆的铲斗,电子控制阀向液压致动器供应液压流体 提高和降低了工具,由电子控制器主动控制。 随着具有工具的车辆以更高的速度运输,该工具倾向于反弹,从而在液压系统中产生升高和降低工具的压力尖峰。 通过在液压系统中主动产生随机或取消液压脉冲来消除压力尖峰。
