Actuator assembly for translating a movable element of a driveline component

摘要

An actuator assembly with first and second sleeves, a barrel, a follower, a groove, a spring, and an output member that is coupled to the second sleeve. The first sleeve has a first externally toothed body, a first flange, which extends radially outwardly from the first body, and a first bore. The barrel is received in the first bore and is rotatable therein. The follower is fixed to one of the barrel and the first sleeve and is received in the groove, which is formed in the other one of the barrel and the first sleeve. The second sleeve has a second body with an internally toothed second bore. The second sleeve is disposed about the first sleeve such that internal and external teeth are meshed to axially slidably but non-rotatably couple the first and second sleeves. The spring is disposed between the first flange and the second sleeve.

主权项

1. An actuator assembly for selectively operating a component of a driveline, the actuator assembly comprising:
a first sleeve having a first sleeve body, a first flange and a first internal bore that is disposed about an actuation axis, the first sleeve body having a plurality of external teeth, the first flange extending radially outwardly from the first sleeve body; a barrel received in the first internal bore and rotatable about actuation axis; a cam follower fixedly coupled to one of the barrel and the first sleeve, the cam follower being received in a cam groove formed in the other one of the barrel and the first sleeve; a second sleeve having a second sleeve body, the second sleeve body defining a second internal bore having a plurality of internal teeth formed thereon, the second sleeve being disposed about the first sleeve such that the internal teeth are meshed with the external teeth to thereby axially slidably but non-rotatably couple the second sleeve to the first sleeve; a first spring disposed between the first flange and the second sleeve; and an actuator output member coupled to the second sleeve for movement therewith along the actuation axis.
