Abstract
An actuator module for a driveline assembly includes, among other things, a cover housing and a fork driving unit supported by the cover housing. The fork driving unit includes a fork driver and a pusher assembly coupled to the fork driver by spaced apart pusher ends. The fork driving unit also includes a drive assembly carried by the pusher assembly to translate the fork driver relative to the cover housing. The fork driving unit further includes a spring that biases the pusher assembly and fork driver to a neutral position.
Claims17
An actuator module for a driveline assembly comprising:
- a cover housing;
- a fork driving unit supported by the cover housing, the fork driving unit including:
- a fork driver axially slidably supported by an unthreaded portion of a fork shaft between multiple shift positions;
- a pusher assembly coupled to the fork driver by spaced apart pusher ends;
- a drive assembly arranged parallel to the fork shaft, the drive assembly carried by the pusher assembly to translate the fork driver relative to the cover housing, the drive assembly includes a threaded shaft and a drive nut with a threaded inner diameter that threadingly engages the threaded shaft, the threaded shaft parallel to the fork shaft, the pusher assembly includes first and second pushers joined by the drive nut;
- and
- a spring being axially slidably carried by the threaded shaft, biasing the pusher assembly and fork driver to a neutral position.

- and
- a spring biasing the pusher assembly and fork driver to a neutral position;
- wherein the fork driver includes first and second walls extending from a central portion, the first and second walls have shaped apertures, and the pusher ends are received in the shaped apertures to permit the pusher assembly to axially slide relative to the fork driver between the neutral position and a transition position while preventing rotation of the pusher assembly relative to the fork driver;
- and
- wherein the drive nut has both left-hand threads and right-hand threads, each of the first and second pushers includes a flange seat received in a respective shape aperture, and one end of the spring engages the first wall and the flange seat of first pusher, and another end of the spring engages the second wall and the flange seat of the second pusher.
