Title: Mounting device for engine
Inventor: KAKIMOTO TOSHIHIKO
IPC: B60K5/12
Filed: 1980-05-02
Abstract: PURPOSE: To control vertical vibration not to be transmitted, by arranging a mount insulator having fluid damping function in addition to an ordinary mount insulator.  
     CONSTITUTION: The mount insulator 8 is arranged between the power unit 1 and the cross-member 5 below the roll axle line RC of the power unit 1. This mount insulator 8 is sufficiently transformed to the vibration in the direction of the roll, as its mount rubber 14 has extremely low rigidity. When vertical vibration is applied to the insulator, change occurs in the volume in the upper and the lower chambers 18 and 19 of a fluid chamber 16. The change of fluid pressure in the upper and the lower chambers 18 and 19 due to slight vibration is compensated by keeping the opening of the interconnecting holes 21 by the screen boards 24a and 24b not acting. Therefore, confined noise is prevented by the rubber 14 from generating. When large vibration is applied to the insulator, the action fluid reciprocates between the upper and the lower chambers 18 and 19 passing through the pipe 20, and vibration is reduced by the orifice action of the pipe 20.
