Description of function:

Steering actuation function

• Via the rotor (229) and the rotary disc valve (609), the volume flow is released to the piston or the piston rod side of the steering cylinder (323) as a function of sense of rotation and rotational speed of the steering wheel. Here, the displacing surface of the steering cylinder (323) is connected with the return line to the tank via the rotary disc valve (609).
• As soon as there is no more steering motion, leaf springs bring the inner and outer rotary discs (609) back to neutral position. Now both sides of the steering cylinder are shut off again and the connection from the pump (218) to the tank is re-established

Emergency steering
function

• When the steering system is not supplied any more externally by pump (218), the non-return valve (742) closes and thus ensures that no oil will escape from the steering system.
• When actuating the steering in one direction, the inner and outer rotary disc of the rotary disc valve (609) are twisted against each other correspondingly. Now the oil can be conveyed from one side of the steering cylinder (323) via non-return valve (728) to the other side through human power by driving the rotor (229).
• On machines with one steering cylinder (323), a reservoir in the return line to the tank compensates the volumetric difference between the piston and piston ring surface.
• When actuating the steering in one direction, the inner rotary disc (609) is twisted against the outer rotary disc (609) by up to 8°. During this process, the return line from the pump (218) to the tank is closed and the connection to the proportioning pump (229) is released.
