Noise and vibration damper for a transmission shift lever

A damper for connecting an end of a first lever member to an end of a second lever member comprising:

• a hollow housing having first and second open ends and first and second pairs of aperture formed therethrough;
• a first hollow liner disposed within said housing having a pair of aperture formed therethrough, said first liner adapted to receive therein the end of the first lever member extending through said first open end of said housing, said first liner being spaced apart from said housing to define a first radially extending space therebetween;
• a first pin extending through said first pair of housing apertures and said first liner apertures;
• a first pair of bushings formed from a bushing material, said first bushings being mounted on the ends of said first pin and being disposed within said first housing apertures for supporting each end of said first pin within said first housing apertures;
• a second hollow liner disposed within said housing having a pair of apertures formed therethrough, said second liner adapted to receive therein the end of the second lever member extending through said second open end of said housing, said second liner being spaced apart from said housing to define a second radially extending space therebetween, said liners being spaced apart from each other to define an axially extending space therebetween;
• a second pin extending through said second pair of housing apertures and said second liner apertures;
• a second pair of bushings formed from a bushing material, said second bushings being mounted on the ends of said second pin and being disposed within said second housing aperture for supporting each end of said second pin within said second housing apertures;
• and
• vibration dampening material disposed in said radially and axially extending spaces for connecting said liners to said housing, said bushing materials being separate from and relatively rigid in comparison to said vibration dampening material.

A damper adapted to be connected to an end of a lever member comprising:

• a hollow housing having an open end and a pair of apertures formed therethrough;
• a hollow liner disposed within said housing having a pair of apertures formed therethrough, said liner adapted to receive therein the end of the lever member extending through said open end of said housing, said liner being spaced apart from said housing to define a radially extending space therebetween;
• annular collar means connected about said open end of said housing and including a portion which extends axially along only a portion of an inner surface of said housing adjacent to said open end for reducing said radially extending space;
• a pin extending through said pair of housing apertures and said liner apertures;
• and
• vibration dampening material disposed in said radially extending space for connecting said liner to said housing.

• annular collar means connected about said first open end of said housing and including a portion which extends axially along only a portion of an inner surface of said housing adjacent to said first open end for reducing said radially extending space;
• a first pin extending through said first pair of housing apertures and said first liner apertures;
• a second hollow liner disposed within said housing having a pair of apertures formed therethrough, said second liner adapted to receive therein the end of the second lever member extending through said second open end of said housing, said second liner being spaced apart from said housing to define a second radially extending space therebetween, said liners being spaced apart from each other to define an axially extending space therebetween;

• a second pin extending through said second pair of housing apertures and said second liner apertures;
• and
• vibration dampening material disposed in said radially and axially extending spaces for connecting said liners to said housing.

A damper for a shift lever assembly adapted to be connected to an end of a lever member comprising:

• a hollow housing having an open end and a pair of apertures formed therethrough;
• a hollow liner disposed within said housing having a pair of apertures formed therethrough, said liner adapted to receive therein the end of the lever member extending through said open end of said housing, said liner being spaced apart from said housing to define a radially extending space therebetween, an enlarged diameter portion being formed on said liner and disposed adjacent to said open end of said housing for reducing said radially extending space;
• a pin extending through said pair of housing apertures and said liner apertures;
• and
• vibration dampening material disposed in said radially extending space for connecting said liner to said housing.
