Abstract: A hydraulic cylinder may include a housing and a rod extending from a working end positioned outside the housing through a rod end of the housing to a piston end positioned within the housing. The hydraulic cylinder may also include a piston arranged on the piston end of the rod and configured to articulate within the housing. The hydraulic cylinder may also include a cap end secured to the housing and having a pocket for receiving a sensor. The pocket may have a cylindrical sidewall. The cap end may include a bore extending therethrough and arranged generally tangential to the sidewall where the bore extends into the cap end, breaches the sidewall, and extends further passed the pocket. The hydraulic cylinder may also include a retention pin configured for placement in the bore and for an interference fit with the sensor when the sensor is arranged in the pocket.

Abstract: Cylinder sensor assembly includes a sensor with pressure pipe extending from the first sensor axial face of a sensor body, an annular face seal adapted to be disposed between the first sensor axial face and an endcap external axial face, and a sensor retention assembly. The sensor retention assembly includes a plurality of fasteners and a retainer body having a retainer distal face, a plurality of through holes and an internal chamber with a radially-extending flange extending into the internal chamber with the internal chamber open to the retainer distal face. The sensor body is disposed within the internal chamber adjacent the radially-extending flange.

Abstract: An overspeed protection method for a machine having an engine drivably coupled to a pump is disclosed. The method includes determining a speed of a rotatable component connected to the engine based on an engine speed and determining a minimum power limit based on the speed of the rotatable component. The minimum power limit corresponds to a minimum power required to retard the engine in order to prevent an overspeed condition of the rotatable component. The method further includes determining a minimum flow limit based on a predetermined relationship between the minimum power limit and the minimum flow limit. The minimum flow limit corresponds to a required flow of the pump in order to provide the minimum power limit. The method further includes regulating the pump in order to achieve the minimum flow limit.

Abstract: The present disclosure relates to a system and method for arbitrating between joystick inputs. The system generates a first command based on the first input if the first input has a non-zero value, and generates a second command based on the second input if the first input has a zero value and the second input has a non-zero value. The system thereby allows two different inputs to control a single commanded function.

Abstract: A computer-based method for calibrating a solenoid-controlled excess flow control valve that couples a first hydraulic circuit to a second hydraulic circuit is provided. The method includes determining a start-of-flow current at which hydraulic fluid begins to flow, closing the valve, sending an actuator command to the second hydraulic circuit, determining a first flow through the hydraulic actuator, opening the valve by setting the solenoid current to a calibration-flow current, sending the actuator command to the second hydraulic circuit, determining a second flow through the hydraulic actuator, calculating a flow difference, determining a calibration-flow valve command associated with the flow difference, determining a maximum-flow current based on the start-of-flow current, the calibration flow current, and the calibration-flow valve command, and creating a valve calibration table based on the start-of-flow current, the maximum-flow current and a valve response table.

Abstract: An electronic torque-angle instrument including a generally tubular body having a gripping section and a pivoting head for engaging a workpiece, such as a nut or bolt, and a housing associated with the body and containing electronics, including a microprocessor, which permit individual or simultaneous measurement of torque and angle applied to the workpiece. The microprocessor includes stored programs which interpret a signal from an input, such as a gyroscopic sensor, and sends the interpreted signal to an output means. The signal is finally displayed as an accurate torque measure and/or angle measure from the output means.
