Abstract
A continuously active pressure accumulator power transfer system for a vehicle or the like comprises an engine, a pump driven by the engine, a main pressure accumulator maintained at a substantially constant fluid pressure and fluid volume by the pump during operation, a fluid motor for propelling the vehicle which is supplied with driving fluid pressure from the main pressure accumulator and a second pressure accumulator at a lower pressure then the main accumulator for supplying fluid to at least one vibration isolation mount.
Claims18
A vibration isolating support mounting system for supporting a load of a first member on a second member and for attenuating transmission of vibrations between said members, said system comprising:
- a plurality of load support vibration isolation mounts for disposal at spaced apart locations between the first and second members, each of said mounts including a first mount part securable to the first member, a second mount part securable to the second member, guide means for guiding relative movement of the first and second mount parts, and first spring cushion means and a high pressure hydraulic fluid medium means acting in series between the first and second mount parts for attenuating vibration induced force transfer between said first and second mount parts,
- a hydraulic fluid accumulator,
- means for maintaining a predetermined pressure of hydraulic fluid in the accumulator, and
- high pressure fluid line means for communication the accumulator pressure with high pressure hydraulic fluid medium means of the load support mounts, said high pressure hydraulic fluid medium means of the mounts being arranged in series along said high pressure fluid line means.
A vibration isolation support mounting system for supporting a load of a first member on a second member and for attenuating transmission of vibrations between said members, said system comprising:
- a plurality of load support vibration isolation mounts for disposal at spaced apart locations between the first and second members, each of said mounts including a first mount part securable to the first member, a second mount part securable to the second member, guide means for guiding relative movement of the first and second mount parts, and first spring cushion means and high pressure hydraulic fluid medium means acting in series between the first and second mount parts for attenuating vibration induced force transfer between said first and second mount parts,
- a hydraulic fluid accumulator with second spring cushion means for vibration insulation,
- means for maintaining a predetermined pressure of hydraulic fluid in the accumulator,
- high pressure fluid line means communicating the hydraulic fluid in the accumulator with the high pressure hydraulic fluid medium means of the load support mounts, and wherein said first and second spring cushion means are gas cushions, and wherein means are provided for communicating the gas of said first spring cushion means of the mounts in series with the gas of said second spring cushion means of the accumulator.
In combination, a load, a support and a vibration isolation support mounting system for supporting the load with respect to the support and for attenuating transmission of vibrations between the load and support, said mounting system comprising:
- a plurality of load support vibration isolation mounts for disposal at spaced apart locations between the load and the support, each of said mounts including a first mount part securable to the load, a second mount part securable to the support, guide means for guiding relative movement of the first and second mount parts, and first spring cushion means and high pressure hydraulic fluid medium means acting in series between the first and second mount parts for attenuating vibration induced force transfer between said first and second mount parts,
- a hydraulic fluid accumulator,
- means for maintaining a predetermined pressure of hydraulic fluid in the accumulator, and
- high pressure fluid line means for communicating the accumulator pressure with the high pressure hydraulic fluid medium means of the load support mounts, said high pressure hydraulic fluid medium means of the mounts being arranged in series along said high pressure fluid line means.
