Actuator Assembly
First Claim
1. An actuator assembly comprising:
- a screw shaft having a shaft axis;
a drive arrangement pivotally supported about the screw shaft axis for driving the screw shaft; and
a rod mounted to the drive arrangement at a location off the shaft axis for providing a primary function of reacting torque about the shaft axis on the drive arrangement, the rod having a rod axis and being arranged to provide a load path that experiences load in a direction along the rod axis in reaction to torque on the drive arrangement,wherein the rod comprises a device which provides a secondary function for the actuator assembly based on the load experienced along the rod load path.

Abstract
An actuator assembly may comprise a screw shaft having a shaft axis; a drive arrangement pivotally supported about the screw shaft axis for driving the screw shaft, e.g., about the shaft axis or along the shaft axis, and a rod mounted to the drive arrangement at a location off the shaft axis for providing a primary function of reacting torque about the shaft axis on the drive arrangement. The rod may comprise a rod axis and provide a load path along the rod axis for reacting torque. The rod may also comprise a device for which provides a secondary function for the actuator assembly based on the load experienced along the load path provided by the rod.

12. A method of reacting torque on an actuator assembly, wherein the actuator assembly comprises a screw shaft having a shaft axis, a drive arrangement pivotally supported about the screw shaft axis for driving the screw shaft, and a rod for connection to a frame, wherein one end of the rod is connected to the drive arrangement at a location off the shaft axis, the rod having a rod axis along which load is experienced resulting from torque on the drive arrangement;
- the method comprising;
using the rod to provide a load path which can react torque on the drive arrangement as a primary function of the rod; and using the rod load path to operate a device which is part of the rod in order to provide a secondary function for the actuator assembly based on the load experienced along the rod load path. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
