Mounting mechanism for an automotive air conditioning compressor

Claim 2

In a mounting mechanism for connecting a compressor of an automobile air conditioning system in a mounted position on an automobile engine including a mounting bracket affixed to the engine, a flange portion projecting from an outer peripheral surface of the compressor, and bolt-nut mechanisms connecting between the mounting bracket and the flange portion of the compressor with a drive shaft of the compressor being disposed parallel to a drive shaft of the engine, the improvement comprising: said mounting bracket having at least one first hole, said flange portion having at least one second hole, said first and second holes being aligned with one another in the mounted position of the compressor; axial vibration absorbing means disposed in one of said first and second holes for absorbing axial vibration of the compressor, a bolt of said bolt-nut mechanisms passing through said axial vibration absorbing means to connect the mounting bracket to the flange portion, said axial vibration absorbing means and said bolt being substantially parallel to said compressor and engine drive shafts: and coupling means connected between the compressor and the mounting bracket for fixing the radial spacing between the compressor and the mounting bracket, wherein said coupling means includes at least one plate with one end of said plate being attached directly to the mounting bracket, the other end being connected to the compressor by said bolt.

Claim 3

The mounting mechanism of claim 1 wherein said vibration absorbing means comprises inside and outside ring spacers and a vibration absorbing material disposed in an annular gap between said ring spacers.

Claim 4

The mounting mechanism of claim 2 wherein said vibration absorbing material is a vibroisolating rubber.

Claim 5

The mounting mechanism of claim 1 wherein said coupling means is made of a high strength material.

Claim 6

The mounting mechanism of claim 4 wherein said high strength material is substantially rigid and non-compressible in the radial direction relative to the drive shaft of the compressor and bendable in the axial direction relative thereto.

Claim 7

The mounting mechanism of claim 1 wherein said coupling means is made of an electrically conductive material.

Claim 8

The mounting mechanism of claim 4 wherein said couping means is made of an electrically conductive material.

Claim 9

The mounting mechanism of claim 1 wherein said coupling means includes at least one pair of metal plates.

Claim 10

In a mounting mechanism for connecting a compressor of an automobile air conditioning system in a mounted position on an automobile engine including a mounting bracket affixed to the engine, a flange portion projecting from an outer peripheral surface of the compressor, and bolt-nut mechanisms, including a plurality of bolts, connecting between the mounting bracket and the flange portion of the compressor with a drive shaft of the compressor being disposed parallel to a drive shaft of the engine, the improvement comprising: said mounting bracket having at least one first hole, said flange portion having at least one second hole, said first and second holes being aligned with one another in the mounted position of the compressor; axial vibration absorbing means disposed in one of said first and second holes for absorbing axial vibration of the compressor, a respective one of the bolts passing through said axial vibration absorbing means to connect the mounting bracket to the flange portion; and coupling means connected between the compressor and the mounting bracket for fixing the radial spacing between the compressor and the mounting bracket wherein said coupling means includes at least one pair of metal plates, the plates of said at least one pair being located at opposite ends of the compressor with one end of each plate being attached directly to the mounting bracket, the other end of one of the plates of said at least one pair being connected to the compressor by said respective one of the bolts and the other end of the other of the plates of said at least one pair being connected to the compressor by another bolt of said bolt-nut mechanisms which passes through a second vibration absorbing means for absorbing axial vibration of the compressor.

Claim 11

In a mounting mechanism for connecting a compressor of an automobile air conditioning system in a mounted position on an automobile engine including a mounting bracket affixed to the engine, a flange portion projecting from an outer peripheral surface of the compressor, and bolt-nut mechanisms, including a plurality of bolts, connecting between the mounting bracket and the flange portion of the compressor with a drive shaft of the compressor being disposed parallel to a drive shaft of the engine, the improvement comprising: said mounting bracket having at least one first hole, said flange portion having at least one second hole, said first and second holes being aligned with one another in the mounted position of the compressor; axial vibration absorbing means disposed in one of said first and second holes for absorbing axial vibration of the compressor, a respective one of the bolts passing through said axial vibration absorbing means to connect the mounting bracket to the flange portion; and coupling means connected between the compressor and the mounting bracket for fixing the radial spacing between the compressor and the mounting bracket wherein said coupling means includes at least one pair of metal plates, the plates of said at least one pair being located at opposite ends of the compressor with one end of each plate being attached directly to the mounting bracket, the other end of one of the plates of said at least one pair being connected to the compressor by said respective one of the bolts and the other end of the other of the plates of said at least one pair being connected to the compressor by another bolt of said bolt-nut mechanisms which passes through a second vibration absorbing means for absorbing axial vibration of the compressor.
