Abstract: A method of assisting a steering effort in a hydraulic steering system is provided. The method includes measuring a pressure with a pressure sensor assembly. The method also includes calculating an input torque with a controller. The method further includes measuring at least one vehicle condition with at least one vehicle sensor and sending a vehicle condition signal to the controller. The method yet further includes determining a current required to operate an actuator with the controller.

Abstract: A power steering system includes a steering column assembly, a steering gear assembly, and a pressure sensor, and a torque sensor. The steering column assembly has a steering shaft and the steering gear assembly is operatively connected to the steering shaft. The steering gear assembly has an input shaft that extends through a valve housing and extends into a rack housing. The pressure sensor is arranged to provide a pressure signal indicative of a fluid pressure of at least one of a first cavity and a second cavity disposed within the rack housing.

Abstract: A reservoir assembly for retaining a fluid includes a body having a base and external side walls defining a cavity. A baffle has a top surface spanning the cavity and includes a peripheral wall substantially conforming to the external side walls and extending to the base. A lid is connected to the body. The cavity is divided into a first, second and third compartment by a cooperation between the top surface of the baffle, a plurality of walls of the baffle, the base of the body and the external side walls of the body. The first and second compartments are in fluid communication with each other through the third compartment. An inlet port and an outlet port for allowing fluid to enter and exit the cavity are fluidly connected to the body and are fluidly connected to each other by the first compartment to direct a flow of the fluid.

Abstract: A power steering system for translating movement to a pair of wheels of a vehicle having an engine is disclosed. The system includes a steering assembly adapted for coupling engagement to the wheels for turning the wheels. The system includes a hydraulic pump having a pump input and a pump output and is coupled to the steering assembly and a planetary gear set. The system also includes a steering shaft operatively connected to the hydraulic pump for controlling a direction of the pump output and coupled to the steering assembly. The system further includes a variable-ratio drive mechanism having an electric motor and a controller. The electric motor is coupled to the planetary gear set and the controller communicates with the electric motor for controlling a rotational speed of the planetary gear set to maintain the pump output.

Abstract: A power assist steering system including a valve housing and a proportional control valve supported within the valve housing, further includes a pressure transducer arranged with respect to the proportional control valve for determining an amount of actuation of the proportional control valve. A pressure signal is sent from the pressure transducer to a control for determining an amount of current to be sent to an electromagnetic apparatus within the power assist steering system for overcoming a pull force.

Abstract: Shaft heat treatment apparatus includes a heat treatment station having a path through which a shaft travels in an axial direction while rotating for heat treating successive axial increments thereof. The shaft is supported by a pair of opposing support jaws at one or more shaft locations intermediate the shaft ends to reduce shaft warpage during heat treatment. The support jaws are transversely movable between shaft-engagement positions and open positions that allow passage of the shaft location through the station. Cam surfaces disposed in proximity to the treatment station engage cam follower surfaces of the support jaws as each pair of support jaws approaches the treatment station to urge the support jaws from the shaft-engagement positions to the open positions to bypass the station without colliding therewith.
