摘要： [Problem]To prevent an eccentric load from occurring in a nut member of a linear actuator and ensure a longer service life of the nut member.[Solution]The nut member is coupled to a driven member by a contact force equalizing mechanism having two rotation axes which are virtually perpendicular to each other, to absorb slight inclination between the nut member and the driven member and prevent occurrence of an edge load; also the point of intersection which is obtained when the two rotation axes are projected toward a threaded shaft is set as an optimum point of application of load for the nut member to let an external force transmitted from the driven member act on the optimum point of application of load to equalize the loads applied to the contact portions between the nut member and the threaded shaft and thereby prevent an eccentric load from occurring in the nut member.

摘要： In a method for utilizing a wedge engagement mechanism as means for retaining an output shaft without requiring a large driving power, there is a need for preventing fatigue life of an actuator from being reduced as a result of stress at contacting portions of parts of wedge engagement portions of the wedge engagement mechanism becoming large.In a linear actuator that converts rotary motion of a drive unit for rotation to linear motion through a rotary motion-to-linear motion conversion mechanism, a one-way mechanism is disposed upstream of the rotary motion-to-linear motion conversion mechanism in a rotational drive path, to thereby inhibit, with a small wedge engagement force, the output shaft from being driven by an external force, achieving reduction in the stress at the contacting portions.

摘要： This invention relates to a fault diagnosis system for hydraulic pumps in a work vehicle, which is economical and permits sure identification of one or more trouble-developed ones of the hydraulic pumps.Pressure sensors 61-64 are arranged on pressurized fluid lines 30,40, which extend to a tank T from points immediately out of center bypasses of flow control valves 21,231-234,451-454,26 communicated to hydraulic pumps 1-6. Solenoid-operated directional control valves 51-56 are interposed in input circuits of individual regulators 11-16 so that, upon excitation, a pressure of a pilot pump 7 is introduced into the regulators 11-16. When all the flow control valves are brought into neutral positions thereof and a determination is instructed through a switch 80, one of the solenoid-operated directional control valves is excited by a signal from a processor 70 so that pressurized fluid is delivered at a maximum flow rate from the corresponding hydraulic pump. A detection value of the corresponding pressure sensor at this time is translated into a flow rate, which is then stored. These procedures are performed with respect to the individual hydraulic pumps successively. Based on a flow rate obtained in every determination, a fault diagnosis of the corresponding particular hydraulic pump is performed.

摘要： A hydraulic drive system for hydraulic working machines has a variable displacement hydraulic pump, at least one actuator driven by the hydraulic fluid, a directional control valve of center bypass type for controlling the flow of the hydraulic fluid, a center bypass line for connecting the center bypass passage of the control valve to a reservoir and a fixed restrictor disposed in the center bypass line. A first control signal that determines a first target displacement of the hydraulic pump is determined by using the pressure generated by the fixed restrictor. A second control signal is generated for determining a second target displacement of a hydraulic pump. A third control signal, which is the larger one of the first and second control signals, provides a target displacement that is applied to a pump regulator that controls the displacement of the hydraulic pump. A metering characteristic as good as the conventional one can be obtained in the case of a light load, and a satisfactory metering characteristic can be achieved in the case of a heavy load, as a result.
