Publication number: 20160280292Abstract: A two track tractor with an active suspension system for reducing pitch jerk and a method of operation thereof utilizes a position sensor between a nose of the tractor and a front axle assembly connected to a forward rolling element. The gap between the nose and the front axle is continually measured and an average gap value is produced. An active suspension system is controlled by a microprocessor to vary the pitch angle between the tractor body and the axle assembly in order to maintain a target nose gap while limiting the pitch jerk experienced by the operator.Type: ApplicationFiled: March 25, 2016Publication date: September 29, 2016Inventor: Ronald L.

Patent number: 6213870Abstract: A rotating concave grain threshing system has a rotor positioned within a concave. The rotor and concave are each rotatable in different preselected speeds and directions through respective transmissions connected to a power source. Measurements are taken corresponding to a physical property of the crop being harvested and the torque induced on the concave. A signal is generated and is responsive to changes in the measurements and delivered to a controller. The controller will then create a controlling signal corresponding to a difference between the desired physical property and the measured physical property and/or the desired torque and the measured torque being greater than a preselected amount. An actuator receives the controlling signal and changes the speed of the concave in response to the magnitude of the received controlling signal.Type: GrantFiled: March 24, 1999Date of Patent: April 10, 2001Assignee: Caterpillar Inc.Inventor: Ronald L.

Patent number: 5878569Abstract: The energy conversion system of the subject invention converts the energy from a source of pressurized fluid, such as a free-piston engine and a storage accumulator, to a work system at various pressure levels. This is accomplished by providing power modifying units which act to efficiently reduce the pressure level of the fluid from the source of pressurized fluid to the various pressure levels. A control arrangement monitors the operating pressures in the actuators and selects the path of pressurized fluid having the lowest pressure level needed to perform the task. Additionally, exhausted fluid containing energy is utilized by regenerating the fluid back to the inlet of the actuator or by directing it through the appropriate power modifying unit to amplify the pressure therein and supplement or recharge the source of pressurized fluid.Type: GrantFiled: September 3, 1997Date of Patent: March 9, 1999Assignee: Caterpillar Inc.Inventor: Ronald L. Satzler

Patent number: 5863104Abstract: An edge scraper device for the inboard edge of a belted track-type vehicle removes debris from the track edge as the vehicle operates in muddy or trash-laden environments by close-proximity relationship to the track edge. Spring biasing and adjustment devices retain the scraper device in a functionally close proximity to the track edge. The edge scraper device is mounted substantially above the track to prevent fallen debris from accumulating on the device.Type: GrantFiled: September 16, 1997Date of Patent: January 26, 1999Assignee: Caterpillar Inc.Inventor: Ronald L.
