Patent number: 11884151Abstract: Systems and methods for a power take-off (PTO) assembly. The PTO assembly, in one example, includes a bi-directional pump in fluidic communication with a fluid reservoir and a hydraulic system and a disconnect clutch configured to mechanically disengage and disconnect the bi-directional pump from a transmission when a prime mover is in operation, and mechanically engage and connect the bi-directional pump to the transmission when the prime mover is shut down. The PTO assembly further includes an electro-mechanical valve configured to trigger engagement and disengagement of the disconnect clutch.Type: GrantFiled: March 23, 2023Date of Patent: January 30, 2024Assignee: DANA BELGIUM N.V.Inventors: Kurt Cattoor, Jan A.

Publication number: 20240003418Abstract: A transmission system is provided. The transmission system includes an electric motor rotationally coupled to a first pump, a second pump, and a third pump via a drive shaft, where an output of the first pump is in fluidic communication with a lubrication circuit and where an output of the third pump is in fluidic communication with an actuation circuit. The transmission system further includes a valve fluidly coupled to the output of the first pump and an output of the second pump and a controller including instructions stored in non-transitory memory that when executed during a first operating condition, cause the controller to selectively operate the valve based on a change in one or more operating conditions in the transmission system.Type: ApplicationFiled: June 14, 2023Publication date: January 4, 2024Inventors: Jan A. BEDERT, Bert HANNON

Publication number: 20230256807Abstract: Methods and systems for a vehicle transmission are provided. An electromechanical transmission system includes, in one example, a power take-off (PTO) clutch configured to, in a first position, permit a motive power source shaft to solely drive a PTO. The PTO clutch is further configured to, in a second position, permit a first electric machine and a second electric machine to continuously vary a torque that is supplied to the PTO by the motive power source shaft.Type: ApplicationFiled: January 16, 2023Publication date: August 17, 2023Inventors: Bert HANNON, Riccardo MORSELLI, Jan A.

Patent number: 11312341Abstract: A controllable hydrodynamic retarder system for a transmission including an electronic controller unit (ECU) for selecting and controlling brake torque by adjusting a retarder outlet pressure is described. The system can include an algorithm to calculate a retarder outlet pressure set point or tables or brake torque curves or profiles to allow the ECU to calculate or look up the functional relationships between the retarder RT outlet pressure, a vehicle or rotor speed, and a brake torque curve selected by the operator to provide the selected RT outlet pressure. The systems disclosed can also include a cooling system or utilize a vehicles engine cooling system. In one embodiment, the cooler can be shared between a transmission and the controllable retarder and can be adjusted to accommodate cooling requirements. The ECU can also make adjustments to the RT outlet pressure to address short term and long term RT overheating protection independent of the cooling system.Type: GrantFiled: April 25, 2018Date of Patent: April 26, 2022Assignee: Dana Belgium N.V.Inventors: Joachim Van Dingenen, Jan A. Bedert, Hein Nevejant

Patent number: 11173882Abstract: A hydrodynamic retarder system for a vehicle is provided. In a first operational state with the vehicle powered on and a retarder deactivated, a pump directs fluid flow from a fluid sump to a retarder inlet valve in the closed position and directs fluid flow to a second sump. In a second operational state with the vehicle on and the retarder activated, the retarder inlet valve moves to the open position directing fluid flow into a retarder chamber and flowing out of the retarder chamber after filling a second volume and discharging to the second sump.Type: GrantFiled: April 10, 2018Date of Patent: November 16, 2021Assignee: DANA BELGIUM N.V.Inventors: Jan A.

Patent number: 7677373Abstract: A torque converter lock-up clutch may be controlled by a lock-up clutch regulator control valve. The valve is utilized to selectively direct a fluid to the torque converter or to a pressure regulator valve. For example, in a hydrodynamic condition of the torque converter, the valve permits fluid to flow to the torque converter. In a lock-up condition of the torque converter, the valve directs fluid to a pressure regulator valve which selectively permits pressure to build in the torque converter.Type: GrantFiled: May 31, 2007Date of Patent: March 16, 2010Assignee: Dana Heavy Vehicle Systems Group, LLCInventors: Jan A.
