5.3 Cycloid gear type powered steering unit
The steering unit can transmit the pressure oil from the flow divider by pipes to the
steering cylinder in terms of the rotating angle of the hand wheel. When the engine stop
running, the charging pump will not work, in this case a man-powered steering should
be adopted. The sketch map of powered steering system is shown as Fig.5.1. The
structure of the steering unit is shown as Fig.5.2.
