Shift lever vibration isolation assembly

Abstract

A shift lever assembly designed to isolate vibrations including an outer can having a bore and an outer wall, an inner can disposed within the bore, a vibration absorbing material positioned within the bore and around the inner can; and a sleeve extending from the outer wall of the outer can. The method of making the shift lever assembly includes positioning an outer can having a bore and an attached sleeve in a mold, positioning an inner can in the mold, within the bore of the outer can, injecting a vibration absorbing material into the mold, thereby filling the space within the bore of the outer can around the inner can, and allowing the vibration absorbing material to cure, thereby securing the inner can within the outer can.

1 . A shift lever vibration isolation assembly, comprising:
 an outer can having an exterior surface and a bore defined by an interior surface of the outer can;   a sleeve on the exterior surface of the outer can;   an inner can disposed within the bore of the outer can and spaced from the interior surface of the outer can;   a vibration absorbing material within the bore of the outer can and around an exterior surface of the inner can and around at least one stop located in the bore of the outer can and outside of the inner can, the at least one stop having at least one gap between the inner can and the outer can, wherein the at least one stop is attached to the inner can by press fit.   
     
     
         2 . The shift lever assembly of  claim 1  wherein the at least one stop has multiple gaps between the interior surface of the outer can and the exterior surface of the inner can. 
     
     
         3 . A shift lever vibration isolation assembly, comprising:
 an outer can having an exterior surface and a bore defined by an interior surface of the outer can;   a sleeve on the exterior surface of the outer can;   an inner can disposed within the bore of the outer can and spaced from the interior surface of the outer can;   a vibration absorbing material within the bore of the outer can and around an exterior surface of the inner can and around at least one stop located in the bore of the outer can and outside of the inner can, the at least one stop having at least one gap between the inner can and the outer can, wherein the at least one stop is attached to the interior surface of the outer can.   
     
     
         4 . The shift lever vibration assembly of  claim 3  wherein the at least one stop is attached to the interior surface of the outer can by at least one weld. 
     
     
         5 . The shift lever vibration isolation assembly of  claim 3  wherein the at least one stop is attached to the interior surface of the outer can by press fit. 
     
     
         6 . The shift lever vibration isolation assembly of  claim 3  wherein the at least one stop has multiple gaps between the interior surface of the outer can and the exterior surface of the inner can.
