Abstract:
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.
