ATTACHMENT ARRANGEMENT FOR A REFRIGERANT COMPRESSOR
The invention relates to an attachment arrangement for vibration decoupling for a refrigerant compressor in motor vehicles. The refrigerant compressor is provided with a mounting opening, wherein a decoupling member made of a vibration damping material is arranged. In the decoupling member a fastening member in form of a hollow-cylindrical fastening sleeve is provided, which is rigid in axial direction. A fastening member axially penetrates the fastening sleeve, by force-closure connecting the fastening sleeve to a fastening point at the motor vehicle over a counterpart. The decoupling member is provided at the mounting opening on the end side in axial direction radially protruding in each case with a flange for form-closed accommodation of the refrigerant compressor.
1 . An attachment arrangement for vibration decoupling for a refrigerant compressor in a motor vehicle comprising:
a refrigerant compressor having a mounting opening formed therein;
a pair of vibration damping decoupling members formed from a vibration dampening material, each of the decoupling members having a radially outwardly extending flange formed on an end thereof, the decoupling members disposed in opposite ends of the mounting opening with at least a portion of the flange disposed adjacent the mounting opening;
a hollow stabilizing member having opposing ends and a longitudinal axis, the stabilizing member extending between the decoupling members in the mounting opening, the opposing ends of the stabilizing member received in the decoupling members, wherein the stabilizing member is substantially rigid in an axial direction; and
a fastening member extending through the stabilizing member and received in a fastening point of the motor vehicle to secure the compressor thereto.
2 . The attachment arrangement according to claim 1 , wherein the opposing ends of the stabilizing member are formed separately from a central segment of the stabilizing member and are attached thereto to form the stabilizing member.
3 . The attachment arrangement according to claim 1 , wherein the opposing ends of the stabilizing member extend through each of the decoupling members and are substantially flush with an end face of the flange of each of the decoupling members in the axial direction.
4 . The attachment arrangement according to claim 1 , wherein each of the decoupling members is a hollow cylindrical sleeve.
5 . The attachment arrangement according to claim 1 , wherein each of the decoupling members is a coating formed on the opposing ends of the stabilizing member.
6 . The attachment arrangement according to claim 1 , wherein the stabilizing member is formed from a metal.
7 . The attachment arrangement according to claim 1 , wherein the stabilizing member is formed from a ceramic.
8 . The attachment arrangement according to claim 1 , wherein the stabilizing member is a hollow cylindrical fastening sleeve.
9 . The attachment arrangement according to claim 1 , further comprising an intermediate piece abutting an end face of the flange of each of the decoupling members.
10 . The attachment arrangement according to claim 9 , wherein the intermediate piece is one of a washer and a spacer.
11 . The attachment arrangement according to claim 1 , wherein the fastening member is a threaded rod.
12 . The attachment arrangement according to claim 1 , wherein the fastening member is a bolt.
13 . The attachment arrangement according to claim 1 , wherein the decoupling members are formed from polytetrafluorethylene.
14 . The attachment arrangement according to claim 1 , wherein the decoupling members are formed from ethylene-propylene-diene-monomer.
