Patent number: 11624409Abstract: Methods and systems are provided for an electromagnetic pulse disconnect assembly. In one example, an electromagnetic disconnect assembly includes an electromagnetic coil assembly including an electromagnetic coil, an armature cam including an annular ring and a plurality of bidirectional cam ramps extending in an axial direction from the annular ring, where the annular ring is adapted to have face-sharing contact with the electromagnetic coil assembly when the electromagnetic coil is energized and be spaced apart from the electromagnetic coil assembly when the electromagnetic coil is de-energized, and a cam follower a plurality of radially extending guides arranged around a circumference of the cam follower and spaced apart from one another via a plurality of elongate apertures, each of the plurality of elongate apertures adapted to receive one of the plurality of bidirectional ramps of the armature cam. The assembly may further include a latching system.Type: GrantFiled: November 2, 2020Date of Patent: April 11, 2023Assignee: Warn Automotive, LLCInventors: Bryan Yoder, Evan Placek, Adam Reiner, Christopher James Boudreau, Adrian Simula, Blake Randall

Publication number: 20230046751Abstract: Systems and processes described herein can use drive line actuators (DLAs) which can be implemented for one or more individual wheels of an electric vehicle (EV) permitting connection and disconnection of at least a portion of the axle and wheel from the electric motor suppling torque. A disconnected wheel and axle can experience less friction, and have less rotational mass then a wheel and axle that is connected to an electric motor, therefore the disconnecting wheels in which torque is not desired can result in increased efficiency and range in an EV.Type: ApplicationFiled: August 13, 2021Publication date: February 16, 2023Inventors: Christopher James Boudreau, Adrian Simula, Craig Feusse

Patent number: 11105406Abstract: Methods and systems are provided for a differential lock assembly for a motorized vehicle. In one example, the differential lock assembly includes a cam gear driven by an electric motor via a transmission of the assembly. The cam gear presses a biasing member against a clutch ring in order to couple a first axle half shaft of the vehicle to a carrier of a differential, and to rotate the first axle half shaft at a same speed as a second axle half shaft driven by the differential.Type: GrantFiled: February 20, 2019Date of Patent: August 31, 2021Assignee: WARN Automotive, LLCInventor: Christopher James Boudreau

Patent number: 11097590Abstract: Methods and systems are provided for controlling operation of a stabilizer bar of a vehicle. In one example, a stabilizer bar includes two shafts joined together by a gas-actuated decoupler. The decoupler may be actuated in order to enable each of the shafts to twist relative to each other.Type: GrantFiled: January 25, 2019Date of Patent: August 24, 2021Assignee: WARN Automotive, LLCInventors: Adrian Simula, Christopher James Boudreau, Craig Feusse
