Abstract
An actuating device for a differential lock has a piston housing having a pressure chamber. An actuator piston is arranged in the pressure chamber of the piston housing. A hydraulic medium tank is provided. A pump conveys a hydraulic medium from the tank to one end of the actuator piston, wherein the actuator piston can move in the pressure chamber and acts on the lock when loaded by the hydraulic medium. One or more conduits connect the hydraulic medium tank and the pressure chamber to one another. The conduit has a temperature-dependent throttle element for adjusting a flow cross-section for the hydraulic medium based on the temperature of the hydraulic medium.
