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, 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) 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 raising of the piston.
ATG brake is equipped with an anti-explosion thrustor and intended for operation in explosion hazard areas.
