Abstract
Transmission systems, disconnect mechanisms, and methods of assembling disconnect mechanisms are envisioned. A disconnect mechanism is adapted to selectively decouple a driving device from a driven device. The disconnect mechanism includes a lever, an inner shaft, an outer shaft, and a housing. The inner shaft is coupled to the lever, the outer shaft is coupled to the inner shaft, and the housing at least partially houses the inner shaft and the outer shaft.
Claims20
A disconnect mechanism comprising:
- a lever;
- an inner shaft coupled to the lever for rotation therewith about a longitudinal axis;
- an outer shaft coupled to the inner shaft for rotation therewith about the longitudinal axis;
- and
- a housing that at least partially houses the inner shaft and the outer shaft,
- wherein the inner shaft includes a splined rod having a first diameter and a collar having a second diameter greater than the first diameter.
A transmission system comprising:
- a driving device including a transmission to transmit rotational power;
- a driven device including a final drive hub to receive rotational power from the driving device;
- and
- a disconnect mechanism to selectively decouple the driving device from the driven device, the disconnect mechanism comprising
- a lever,
- an inner shaft coupled to the lever for rotation therewith about a longitudinal axis,
- an outer shaft coupled to the inner shaft for rotation therewith about the longitudinal axis, and
- a housing that at least partially houses the inner shaft and the outer shaft.
A method of assembling a disconnect mechanism including an inner shaft, an outer shaft, a housing, and a lever, the method comprising:
- advancing the inner shaft into the outer shaft;
- installing the inner shaft and the outer shaft in the housing;
- and
- attaching the lever directly to the inner shaft.
