ABSTRACT:
For simulating hydromechanical actuation of components in a toy model such as a toy excavator having legs and a shovel, means for exclusively mechanical power transmission are provided. These means include actuating units comprising each a cylinder casing and a piston rod slidably arranged therein and displaceable by a threaded spindle in engagement with the piston rod. Rotary motion is transmitted to the threaded spindle by a flexible shaft having plug-in connectors at both ends secured to a core and a protective hose of the flexible shaft. Each flexible shaft is connected with a driving unit installed in the toy model and releasably connected with a rotary power source such as handwheel or an electric motor.
