Abstract
Methods and systems for an actuator cartridge. The actuator cartridge includes an actuation assembly that is rotationally coupled to an actuation motor and a sleeve. The sleeve includes a shift device groove that circumferentially extends around the sleeve and is configured to axially capture a shift device and gaps that extend from an axial side of the sleeve to the shift device groove.
Claims20
An electromechanical actuator cartridge, comprising:
- an actuation assembly comprising:
- a sleeve including:
- a shift device groove that at least partially circumferentially extends around the sleeve and is configured to axially capture an extension of a shift device;
- and
- multiple gaps that extend from an axial side of the sleeve to the shift device groove;
- and
- an actuation motor rotationally coupled to the actuation assembly.
A method for installing an electromechanical actuator cartridge, comprising:
- aligning a pair of grooves that are included in a sleeve of the electromechanical actuator cartridge with shift fork pads that are included in a shift fork of a transmission;
- axially translating the electromechanical actuator cartridge to move the shift fork pads through the pair of grooves and into a fork pad groove that is included in the sleeve;
- and
- rotating the electromechanical actuator cartridge to move the pair of grooves out of radial alignment with the shift fork pads.
A ball screw electromechanical actuator cartridge, comprising:
- a ball screw assembly comprising:
- a sleeve coupled to or incorporated into a nut that threadingly engages a screw shaft;
- wherein the sleeve includes:
- a fork pad groove that circumferentially extends around the sleeve and is configured to axially capture shift fork pads;
- and
- a pair of gaps that extend from an axial side of the sleeve to the fork pad groove;
- and
- an actuation motor rotationally coupled to the screw shaft.
