SINOTRUK 70-ton class heavy-duty mining dump truck Steering Power Cylinder Ball Joint Assembly Tie Rod End WG9770470075
Installed at the end of the steering power cylinder (hydraulic assist cylinder) assembly, it connects to the steering knuckle arm or the tie rod. Its function is to convert the immense hydraulic thrust-generated as the power cylinder extends or retracts-into the steering movement of the wheels, while simultaneously absorbing three-dimensional vibrations and shocks caused by uneven road surfaces.
