Disc brakes with the electrohydraulic thrustors of ZE type are adjusted to the cooperation with brake discs on their lateral surface. Braking torque is created by the spring inbuilt in the body of the thrustor or by the lever system (series 100), which through the compound lever causes pressing down of the brake shoes with friction linings to the friction surface of the brake disc.
Turning on the supply voltage of the thrustor starts the motor and the pump forcing the oil under the piston of the thrustor which causes that the piston moves up and the brake is released. Turning off the supply causes that the piston moves down (under the influence of the spring inbuilt in the thrustor or outside the thrustor- series 100) and the brake is applied. The speed of raising or falling of the piston can be adjusted through the use of the valve delaying the falling or lifting of the piston.
ZE thrustors can be equipped with inductive sensor of piston rod position mounted outside or with external mechanical switch signaling upper or lower position of the piston rod. Above mentioned sensors and switches require appropriate source of supply.
