Abstract
A switchable lever is provided that includes an outer lever, an inner lever pivotably mounted to the outer lever, and a lash adjustable coupling assembly capable of selectively locking the inner lever to the outer lever. The lash adjustable coupling assembly includes an inner rod and an outer cylinder configured to adjustably receive the inner rod. The inner rod can be formed with external threads and the outer cylinder can be formed with internal threads. A lash adjustment spring can be arranged to outwardly urge the inner rod with respect to the outer rod to adjust lash within a switchable lever system.

A switchable lever comprising:
- an outer lever;
- an inner lever pivotably mounted to the outer lever;
- and
- a lash adjustable coupling assembly capable of selectively locking the inner lever to the outer lever, the lash adjustable coupling assembly including:
- an inner rod;
- an outer cylinder configured to adjustably receive the inner rod, the outer cylinder having a first end and a second end;
- and
- a first end of the inner rod configured to receive an external force.
A switchable lever system, comprising:
- a first switchable lever, including:
- a first inner lever;
- a first outer lever pivotably mounted to the first inner lever;
- a first lash adjustable coupling assembly capable of selectively locking the first inner lever to the first outer lever, the first lash adjustable coupling assembly having:
- a first inner rod;
- a first outer cylinder arranged to adjustably receive the first inner rod;
- and
- a first end of the first inner rod actuated by an actuator.
A method of adjusting coupling assembly lash in a switchable lever system, comprising:
- rotating a first inner rod formed with external threads within a first outer cylinder formed with internal threads, the first outer cylinder having a first end and a second end, and disposed within a bore of a first switchable lever;
- and
- setting a lash between a first end of the first inner rod and an actuator to a pre-determined value.
