PROBLEM TO BE SOLVED: To provide an improved MR damper closing assemblies which can better handle increased friction over long periods of damper use.SOLUTION: A closing assembly for a magneto-rheological damper includes an annular housing 22 defining a through bore 28 with first, second, third, fourth, fifth and sixth counter-bores having varied diameters. A wiper seal 52 is disposed in the first counter-bore 38 and an upper seal 58 is disposed in the second counter-bore 40. A guide 67 is disposed in the fourth counter-bore 46. The guide, the upper seal, and the third counter-bore 44 define a first chamber 76. A plate 78 defining a passage 80 is disposed axially below the guide in the fifth counter-bore 48 with a flange extending into the sixth counter-bore 50. A lower seal 84 is disposed in the passage. The guide, the plate, and the fifth counter-bore define a second chamber 94. The first and second chambers separate and contain a lubricating oil adjacent to the upper seal and the lower seal.SELECTED DRAWING: Figure 2 |
