Patent number: 10514084Abstract: A power transmission system is disclosed for infinitely variable speed capability. The power transmission system includes a pair of power units, each configured to deliver a rotational torque to drive an output element. A transmission arrangement receives the rotational torques from the power units and delivers a resulting torque to the output element. The transmission arrangement includes a gear set coupling the one power unit to the output element to deliver torque through a mechanical meshing engagement that is continuously effected between the first power unit and the output element.Type: GrantFiled: October 18, 2017Date of Patent: December 24, 2019Assignee: DEERE & COMPANYInventors: Dwayne B. Watt, G. William Detrick, Randall L. Long

Patent number: 10328795Abstract: An auxiliary drive assembly includes a mounting structure configured to mount a first hydraulic drive component in a fixed position with respect to a second hydraulic drive component along a drive axis. A first shaft coupled to the first hydraulic drive component is configured to rotate with respect to the drive axis. A second shaft coupled to the second hydraulic drive component is configured to rotate with respect to the drive axis. A power takeoff device is arranged along the drive axis between the first and second hydraulic drive components and coupled to the first and second shafts for co-rotation with respect to the drive axis. The power takeoff device is configured to transfer rotational power from the power source as received from the first hydraulic drive component to an auxiliary component of the work vehicle.Type: GrantFiled: February 27, 2017Date of Patent: June 25, 2019Assignee: DEERE & COMPANYInventors: Randall L. Long, G. William Detrick

Patent number: 10207580Abstract: A drive assembly includes a drive housing, a bearing-mounted wheel mount configured to rotate about a rotation axis with respect to the drive housing, and a shift assembly coupled between an input shaft and the wheel mount to selectably cause rotation of the wheel mount various rotational speeds. The shift assembly includes a gear set and a brake arrangement. The gear set has a first gear and a second gear, each being rotatable by the input shaft independent of the other. The brake arrangement has a first brake component and a second brake component. During rotation of the wheel mount at a first rotational speed, the first brake component brakes the first gear with respect to the drive housing. During rotation of the wheel mount at a second rotational speed, the second brake component brakes the second gear with respect to the drive housing.Type: GrantFiled: December 9, 2016Date of Patent: February 19, 2019Assignee: Deere & CompanyInventors: Randall L. Long, Cecil H. Wise, Jr., G. William Detrick

Patent number: 10180185Abstract: A modular assembly is described for a power train. An assembly housing includes first and second cavities connected by an inter-cavity passage. An input shaft and an output shaft linked by a first clutch are disposed, at least in part, in the first cavity. A hydraulic control assembly provides hydraulic control signals to control, at least in part, the first clutch device. A hydraulic quill insert disposed, at least in part, in the inter-cavity passage, includes a plurality of control passages. The hydraulic quill insert receives the hydraulic control signals and directs the signals to control power flow from the input shaft to the output shaft.Type: GrantFiled: July 28, 2016Date of Patent: January 15, 2019Assignee: DEERE & COMPANYInventors: Dwayne B. Watt, G. William Detrick, Cecil H. Wise, Jr.

Patent number: 10099552Abstract: A hydraulic-electric drive assembly for a work vehicle has a hydraulic pump drive including a manifold housing, a power input interface configured to couple with a prime mover for receiving rotational input power, and a plurality of power output interfaces coupled to the power input interface to transmit the input power from the prime mover mechanically at a first drive speed. At least one hydraulic pump is mounted to at least one of the power output interfaces to be driven by the input power from the prime mover. At least one electric generator is coupled to at least one of the power output interfaces to be driven by the input power from the prime mover. The at least one electric generator is configured to convert the input power from the prime mover into electric power.Type: GrantFiled: September 30, 2016Date of Patent: October 16, 2018Assignee: DEERE & COMPANYInventors: Randall L.
