4.8 Temperature control,
filtration and brake fluid
Temperature control, cleaning and brake oil,
function description
The brake system is cooled with oil that circulates through a cooler.
The cooler has a temperature-controlled electric fan that counter-
acts overheating.
Temperature control consists of brake oil tank, brake oil pump,
brake oil filter, accumulator charging valve, wheel brake units, cool-
er, cooling fan, sensor brake oil temperature and thermal by-pass
valve.
The brake oil pump pumps oil (from the tank) which is cleaned in the
oil filter. When the accumulators are charged, the accumulator
charging valve controls oil through the drive axle's brake units and
cools the brakes. The oil passes through the cooler back to tank. An
electric cooling fan increases the air flow through the cooler when
the temperature needs to be lowered. A thermal by-pass valve leads
the hydraulic oil past the cooler if the oil's temperature is too low.
The temperature sensor controls activation of fan and temperature
warning on the display.
