  • Patent number: 12000416
    Abstract: A work machine that can keep the control accuracy of actuators irrespective of temperature variation of a hydraulic operating fluid that passes through flow rate controllers that control the flow rates of supply to the actuators is provided. For this purpose, the flow rate controllers each have a valve body that is disposed on a main hydraulic line connecting a delivery line of a hydraulic pump and the actuator and that moves according to an operation pressure from a solenoid proportional pressure reducing valve, a sampling hydraulic line that branches from the main hydraulic line, and a temperature sensor set on the sampling hydraulic line. The controller is configured to correct a command electrical signal to the solenoid proportional pressure reducing valve according to a signal from the temperature sensor.

  • Patent number: 11965315
    Abstract: The invention of the present application intends to provide a work machine that can ensure high operability by preventing abrupt actuation of an actuator and a shock to a machine body by use of a bleed-off function at the time of starting of the actuator and that can improve the energy-saving performance by reducing a bleed-off flow rate after the starting of the actuator. For this purpose, a controller opens a bleed-off valve at a timing at which an operation device is being operated and before a flow rate of a hydraulic pump starts increasing, and closes the bleed-off valve at a timing at which the operation device is being operated and after the flow rate of the hydraulic pump has started increasing.

  • Patent number: 7934588
    Abstract: A torque damper can comprise a clutch piston arranged within a cover of a torque converter and can be adapted to be moved between a connected position and a non-connected position relative to the cover. Damper springs can be arranged along the circumference of the clutch piston. Connecting members can be arranged abutting against one end of the damper spring and adapted to connect a turbine arranged within the cover and the clutch piston via the damper spring. Damper holders can be arranged abutting against the other end of the damper spring and adapted to hold the damper spring against the compressive force applied to the damper spring from the connecting member. Guide sheets having wear resistance can be interposed between the circumference of the clutch piston and the damper spring and can be adapted to guide the damper spring. A torque input to the cover can be transmitted to the turbine via the clutch piston and the damper springs when the clutch piston is in the connected position.

  • Publication number: 20070251791
    Abstract: A lock-up clutch can include a clutch piston arranged within a cover of a torque converter and adapted to be moved between a connected position and a non-connected position relative to the torque converter cover. A containing recess can be formed on a circumferential edge of the clutch piston for containing damper springs and connecting members for connecting a turbine arranged within the torque converter cover and the clutch piston via the damper springs contained within the containing recess. An independent member forming an outer circumferential portion of the containing recess can be arranged oppositely to the outer surface of each damper spring.
