Patent number: 11970987Abstract: A phasing system for varying a rotational relationship between a first rotary component and a second rotary component includes a gear hub and a cradle rotor. A spider rotor is arranged between the gear hub and the cradle rotor to selectively lock and unlock relative rotation between the gear hub and the cradle rotor. A torsion spring is coupled between the gear hub and the cradle rotor to apply a torque load between the gear hub and the cradle rotor. A planetary actuator is coupled to the gear hub and the spider rotor. The planetary actuator is operable between a steady-state mode, in which relative rotation between the gear hub and the cradle rotor is inhibited, and a phasing mode, in which the planetary actuator receives a rotary input at a predetermined magnitude to selectively provide a relative rotation between the gear hub and the cradle rotor.Type: GrantFiled: March 15, 2023Date of Patent: April 30, 2024Assignee: HUSCO Automotive Holdings LLCInventors: Curtis L. Van Weelden, Dean Wardle, Bryce Johnson

Patent number: 11674573Abstract: A phasing system is provided. A phase angle between the gear hub and the cradle rotor can be driven by a planetary actuator. In some non-limiting examples, an input shaft rotationally coupled between a rotary actuator for rotation therewith. Rotation of the input shaft can unlock relative rotation between the cradle rotor and the gear hub. In some non-limiting examples, the phasing system can include a gear hub and a cradle rotor, and a torsion spring arrange therebetween. The torsion spring can be configured to apply an internal torque load between the gear hub and the cradle rotor to offset an external torque load applied to the gear hub or the cradle rotor.Type: GrantFiled: August 16, 2021Date of Patent: June 13, 2023Assignee: HUSCO Automotive Holdings LLCInventors: Curtis L.

Publication number: 20230050408Abstract: The systems and methods described herein provide an approach for cam phase angle control where an axial or rotational position of an actuator of a cam phaser has a direct relationship to the phase angle of the cam shaft, allowing for accurate cam phasing without the need for cam shaft or crank shaft position sensors. Providing phase angle adjustability without the need for crank shaft or cam shaft position sensors enables control of phase angle solely by sensing the axial or rotational position of the actuator of the cam phaser.Type: ApplicationFiled: August 10, 2022Publication date: February 16, 2023Inventors: Michael Kujak, Todd Wollenberg, Patrick Heithoff, Dean Wardle

Patent number: 11441647Abstract: A linear actuator is provided. The linear actuator includes a rotor assembly including a rotor and a lead screw. The lead screw is rotationally coupled to the rotor for rotation therewith. The linear actuator further includes a stator assembly configured to selectively rotate the rotor in a desired direction, and a body assembly having a shaft and a shaft tube. The shaft is keyed to the shaft tube and prevented from rotating with the rotor. The shaft includes an inner bore configured to threadably receive the lead screw therein. Selective rotation is configured to displace the shaft between an extended position and a retracted position.Type: GrantFiled: January 27, 2020Date of Patent: September 13, 2022Assignee: HUSCO Automotive Holdings LLCInventors: Michael Layne, Dean Wardle, Selena Boltik

Patent number: 11201025Abstract: An electromagnetic actuator having a permanent magnet coupled to an armature of the electromagnetic actuator is provided. The electromagnetic actuator includes a housing, and an armature assembly arranged within the housing. The armature assembly includes an armature and a permanent magnet coupled to the armature. The armature is movable between a first position and a second position, and the permanent magnet defines an axial magnet thickness and the armature defines an axial armature thickness. A ratio of the axial armature thickness to the axial magnet thickness is greater than approximately three.Type: GrantFiled: April 24, 2019Date of Patent: December 14, 2021Assignee: HUSCO Automotive Holdings LLCInventors: Dean Wardle, Michael Fricke
