Electronically controlled mounting structure for mounting power unit on vehicle
First Claim
1. A mounting structure disposed between a body and a power unit of a vehicle for mounting of the power unit on the body, so as to effect vibration damping and isolation under the control of a control device, comprising:
- an elastic body disposed between said body and said power unit of the vehicle;
means for defining a pressure-receiving chamber, in cooperation with said elastic body, said pressure-receiving chamber being filled with an incompressible fluid through which the pressure-receiving chamber is subject to vibrations to be damped or isolated;
means for defining an equilibrium chamber which is filled with said imcompressible fluid, and which communicates with said pressure-receiving chamber through passage means, so as to permit a change in a volume of said pressure-receiving chamber;
a movable member disposed between said pressure-receiving chamber and said equilibrium chamber, and functioning as parts of said means for defining said pressure-receiving and equilibrium chambers, said movable member being movable over a predetermined maximum distance in opposite directions parallel to a direction in which the mounting structure receives said vibrations;
elastic holder means comprising a pair of generally planar elastic members fixed to opposite ends of said movable member for flexibly supporting said movable member such that said movable member is movable in said opposite directions;
guide means for guiding said movable member in said opposite direction in a sliding contact manner; and
drive means connected to said control device, for reciprocating said movable member in said opposite directions along said guide means, over a controlled operating stroke and at a controlled frequency.

Abstract
A mounting structure disposed between a body and a power unit of a vehicle for mounting of the power unit on the body, so as to effect vibration damping and isolation under the control of a control device, including: an elastic body connected to one of the body and the power unit of the vehicle, and partially defining a pressure-receiving chamber filled with an incompressible fluid; an elastic member partially defining an equilibrium chamber filled with the fluid and communicating with the pressure-receiving chamber, so as to permit a change in a volume of the pressure-receiving chamber; a movable member disposed between the pressure-receiving and equilibrium chambers, and exposed to the pressure-receiving and equilibrium chambers, the movable member being movable over a predetermined maximum distance in opposite directions parallel to a direction in which the mounting structure receives vibrations; an elastic holder for flexibly supporting the movable member such that the movable member is movable in the opposite directions; a guide for guiding the movable member in the opposite directions; and a drive device connected to the control device, for reciprocating the movable member, over a controlled operating stroke and at a controlled frequency.

11. An electrically controlled mounting system including a mounting structure disposed between a body and a power unit of a vehicle for mounting of said power unit on said body, so as to effect vibration damping and isolation, comprising:
-
a housing assembly; an elastic body supported by said housing assembly and connected to one of said body and said power unit of the vehicle, said elastic body cooperating with said housing assembly to partially define a pressure-receiving chamber filled with an incompressible fluid which cooperates with said elastic member to receive vibrations to be damped or isolated; an elastic diaphragm member supported by said housing assembly and partialy defining an equilibrium chamber which is filled said incompressible fluid, and which communicates with said pressure-receiving chamber through a passage means, said elastic diaphragm member being elastically yieldable, so as to permit a change in a volume of said equilibrium chamber and thereby permit a change in a volume of said pressure-receiving chamber; a movable member disposed between said pressure-receiving chamber and said equilibrium chamber, so that said movable member is movable over a predetermined maximum distance in opposite directions toward and away from said elastic body and said elastic diaphragm member; elastic holder means supported by said housing assembly and comprising a pair of generally planar elastic members fixed to opposite ends of said movable member, for flexibly supporting said movable member so as to permit said movable member to be moved in said opposite directions; drive means disposed within said housing assembly, between said pressure-receiving and equilibrium chambers, for reciprocating said movable member in said opposite directions; guide means for guiding said movable member in said opposite directions in a sliding contact manner; and a control device connected to said drive means, for controlling said drive means so as to reciprocate said movable member over a controlled operating stroke and at a controlled frequency, said controlled operating stroke being determined by an elasticity of said elastic holder means and a drive force produced by said drive means. - View Dependent Claims (12, 13, 14, 15, 16)
