PURPOSE:To reduce the extent of engine vibrations without entailing any problem of a drop in accelerability, etc., by setting up a hydraulic cylinder between an engine and a chassis, while reducing the engine vibrations at at the time of acceleration and deceleration with the adjustment of engine supporting force. CONSTITUTION:Hydraulic cylinders 12a and 12b are set up between an engine 1 and a chassis 6, and pressure oil is fed or discharged to or from these cylinders each by a hydraulic selector valve 13. And, solenoid valves 14a and 14b are installed in this hydraulic selector valve 13, while a spool valve 15 is selected by a signal out of a control circuit 18. In addition, a hydraulic setting signal to be outputted out of an operator 16 is inputted into this control circuit 18. Likewise, the operator 16 operates the hydraulic setting signal from each signal of throttle valve opening theta, an engine speed (n) and a transmission ratio nt. With this constitution, the hydraulic pressure in these hydraulic cylinders 12a and 12b is controlled according to a running state of the engine 1, whereby vibrations at the time of acceleration and deceleration are reduced with adjustment of supporting force for the engine 1. |
