Influence of Novel Redirector with Bypass Damping on the Performance of Load-Sensing Steering System

Abstract Load-sensing steering systems for articulated loaders are prone to large pressure shocks and oscillations during steering operations, affecting the system stability. An optimized structure of the redirector with bypass damping is proposed to improve this phenomenon. In this structure, orifi...
