DOUBLE TUBE DAMPER WITH STRUCTURAL PRESSURE TUBE

摘要

The present disclosure relates to a shock absorber having a pressure tube which defines a fluid chamber, and a piston assembly. The piston assembly is disposed within the fluid chamber and divides the fluid chamber into upper and lower working chambers. A reserve tube surrounds the pressure tube to define a reservoir chamber between the reserve tube and the pressure tube. The pressure tube is disposed between a rod guide assembly and a lower mount. A structural integrity of the pressure tube is greater than a structural integrity of the reserve tube, and the pressure tube further operates as a principal load bearing component for the shock absorber.

主权项

1. A twin tube shock absorber comprising:
a pressure tube defining a fluid chamber; a piston assembly disposed within the fluid chamber, the piston assembly dividing the fluid chamber into an upper working chamber and a lower working chamber; a lower mount; a rod guide assembly; the pressure tube extending between the lower mount and the rod guide assembly and being in load bearing contact with both the lower mount and the rod guide assembly, so as to be fixed against movement relative to the lower mount and the rod guide assembly, and to act as a principal load bearing component for the shock absorber; a reserve tube surrounding the pressure tube and being in contact with the lower mount, a reservoir chamber being defined between the reserve tube and the pressure tube; wherein a structural integrity of the pressure tube is greater than a structural integrity of the reserve tube, and the reserve tube operating to provide substantially no load bearing operation for the shock absorber.
