Torque Limiting Device For Hydraulic Piston Pump

View page
US Patent:
7114432, Oct 3, 2006
Filed:
Feb 9, 2005
Appl. No.:
11/053804
Inventors:
Nick L Boone - Ames IA, US
Gary R Lingenfelter - Nevada IA, US
Assignee:
Sauer-Danfoss Inc. - Ames IA
International Classification:
F01B 3/02
F01B 31/04
US Classification:
91505, 92 122, 92131, 4172221
Abstract:
A torque control for a hydrostatic piston pump that provides for a servo piston rod that is connected to the swashplate of the pump and connected to a servo piston within a first cavity that receives compensation pressure that urges the servo piston toward the swashplate. The servo piston has a stem that extends into a bore and is in contact with the stem of a maximum displacement piston that extends into a second cavity that is acted upon by system pressure to urge the maximum displacement piston toward the swashplate. Additionally, within the second cavity is a set of Bellville washers that surround the stem of the maximum displacement piston to limit the movement of the maximum displacement piston toward the swashplate.

Displacement Control With Load Feedback And Stroke Control For A Hydraulic Unit

US Patent:
61194565, Sep 19, 2000
Filed:
Jan 21, 1998
Appl. No.:
9/010451
Inventors:
Joseph E. Louis - Panora IA
Gary R. Lingenfelter - Nevada IA
Assignee:
Sauer Inc. - Ames IA
International Classification:
F16D 3102
F15B 910
US Classification:
60444
Abstract:
A displacement control device for a hydraulic unit includes: an actuator for applying operator input force to a movable member for varying displacement of the unit; a control valve having a spool and a sleeve displaceable with respect to each other, one of these being coupled with the movable member and the other being coupled with the actuator, the control valve being capable of generating a control signal based upon the relative displacement of the spool and sleeve; a servo which is operatively connected to the movable member and receives the control signal so as to move the movable member and change the fluid displacement of the unit in response to the control signal; and a bias coupling connecting the spool and the sleeve of the control valve. Thus, a preload force is interposed between and the spool and the sleeve such that relative displacement between the spool and the sleeve takes place when the feedback force exceeds the preload force. Thus, the sleeve moves synchronously with the spool until the feedback force exceeds the preload force.
