A vibration damper including a first spline having a plurality of first teeth, a second spline having a plurality of second teeth, a third spline having a plurality of third teeth and at least one spring interconnected between the first and second splines, wherein the plurality of third teeth are intermediate the plurality of first teeth and the plurality of second teeth, and the at least one spring biases the plurality of first teeth and the plurality of second teeth against the plurality of third teeth. A method of preventing lash in a vibration damper, the vibration damper including a first spline having a plurality of first teeth, a second spline having a plurality of second teeth, a third spline having a plurality of third teeth and at least one spring interconnected between the first and second splines, the method including the steps of: introducing the plurality of third teeth intermediate the plurality of first teeth and the plurality of second teeth; and, biasing the plurality of first teeth and the plurality of second teeth against the plurality of third teeth with the at least one spring.

Method and apparatus for lash prevention using coil springs

The present invention comprises a lash prevention spring of unique design having a plurality of spring legs shaped into an s-curve and an inner circumference formed into at least one spline. The invention also comprises a lash prevention assembly in which the disclosed lash spring is attached to a damper hub and is biased against the several teeth from a turbine hub that extend through the damper hub from its opposite side.
