PURPOSE:To allow a mounting device for a power unit to work with its full expected performance about prevention of restraint of vibrations, by providing an elastic member and an initially coned disc spring arranged in series thereto, and by constituting so as to make correction of the work of a device which is to give the disc spring a preload upon sensing any change of the load the disc spring is bearing. CONSTITUTION:An insulator rubber 15 as an elastic member approx. in a cylindrical form is attached by hot press fast to the oversurface of a bracket 14 to be fixed to the car body 11, and to the oversurface of this rubber 15 No.1 washer 16 approx. in a cylindrical form is attached by hot press. Over this washer 16, No.2 washer 19 is fixed through an initially coned disc spring 18 to partition a space together with the rubber 15 etc. In this space is furnished with the upper and lower plates 24, 25 and an actuator 23 consisting of bellows 27, which couples the members 24, 25 and forms a space 26. The actuator is put in operation according to the pressure of fluid discharged from a communipipe 28. Control of this fluid pressure is made by a solenoid operated valve 31 with the aid of relay circuit 30 in compliance with the output from a displacement sensor 29 which is to sense the displacement of the plate 25. |
