Patent ID: 7032474

Claim:
A shift lever and shift lever vibration isolator combination comprising: a shift lever having a sleeve, said sleeve having a sleeve sidewall defining a cavity, said shift lever having a longitudinal axis and a lateral axis that is perpendicular to said longitudinal axis; a shift lever vibration isolator located within said sleeve; and a mechanical attachment of said shift lever vibration isolator with respect to said sleeve, said mechanical attachment comprising: said shift lever vibration isolator having a laterally disposed attachment bore; said sleeve having a pair of diametrically opposed holes formed therein; and an attachment pin passing through said attachment bore and said holes in said sleeve; wherein said shift lever vibration isolator provides a first stiffness in said longitudinal axis and a second stiffness in said lateral axis, wherein said first stiffness is greater than said second stiffness; and wherein said shift lever vibration isolator provides a first natural frequency of vibration of the shift lever in said longitudinal axis and a second natural frequency of vibration of the shift lever in said lateral axis, wherein said first natural frequency of vibration is higher than said second natural frequency of vibration.
