POWER UNIT MOUNTING DEVICE

摘要

PURPOSE:To reduce the bounce rigidity by communicating the fluid chamber of mounts arranged at the opposite sides of the rotary shaft of power unit to the fluid chamber of auxiliary mount for limiting rotation of power unit around the rotary shaft. CONSTITUTION:A mount 4 encapsulated with non-compressive fluid in a fluid chamber 7 having an opening through the upperface of bottomed tubular case 5 enclosed with resilient wall 6 is arranged between the chassis 1 and the brackets 3 projecting approximately in horizontal from the opposite sidefaces of the crank shaft 2a of engine 2. The fluid chambers 7 are communicated through a conduit 9 arranged with a solenoid valve 18 to be controlled with correspondence to the engine operating condition. While auxiliary mounts 11 are arranged in horizontal direction while facing each other at the opposite sides of brackets 10 projecting upward from the upper face of engine 2. The auxiliary mount 11 is constructed similarly with said mount 4 to communicate the fluid chamber 14 with said fluid chamber 7 through communication tube 17 arranged with an orifice 16.
