Abstract: A steering actuator including a motor having a rotor including opposing input and output ends. A driven gear is supported on the input end of the rotor shaft for rotation with the rotor shaft and the output end provides a rotational output of the steering actuator. An override shaft is supported for rotation parallel to the rotor and a drive gear is supported for rotation with the override shaft wherein the drive gear is longitudinally movable relative to the driven gear to engage and disengage the drive gear relative to the driven gear. A coupling structure is provided on an end of the override shaft for detachable engagement with an auxiliary driver. The auxiliary driver provides a rotational driving force to the override shaft for effecting rotation of the rotor shaft.

Abstract: A retention structure for retaining a heat generating component to a heat dissipating substrate. The heat generating component has a heat transfer surface and an opposing biasing surface, and the heat dissipating substrate has opposing first and second sides. The retention structure has a generally U-shaped retention body including an elongated base having opposing ends, and legs extending from the ends of the base. Each of the legs includes a positioning slot. The substrate includes a pair of passages for receiving the legs therethrough, and a pin structure is positioned on the substrate and extends through the positioning slots in the legs to locate the base of the retention body adjacent to the biasing surface and effect a biasing of the heat transfer surface toward the substrate.

Abstract: A vehicle braking system vacuum booster tandem power piston connection design such that the primary piston and the secondary piston are positioned together forming the tandem power piston. A connection design that provides direct alignment between the primary piston and secondary piston upon assembly and also provides an airtight seal between the primary piston and the secondary piston when assembling the tandem power piston.

Abstract: The present invention includes a system for providing an improved controlled airflow within a vacuum booster system. The system includes a vacuum booster assembly having a primary chamber and a secondary chamber, and an outer tube having a first end and a second end, the first end in communication with the secondary chamber of the vacuum booster assembly. The system additionally includes an airflow control assembly operably coupled to the second end of the outer tube, and an inner tube, concentric to the outer tube, having a first end and a second end, the first end operably coupled to the airflow control assembly, the second end in communication with the primary chamber of the vacuum booster assembly. In the system, air flows from the primary chamber of the vacuum booster assembly to the airflow control assembly within the inner tube and air flows from the airflow control assembly to the secondary chamber of the vacuum booster assembly within the outer tube.
