  • Patent number: 11396231
    Abstract: Overload protection systems and methods are provided for controlling the amount of energy delivered to the drivetrain of work vehicles including axles, transmission, and other components thereof including for vehicles using power boost. A sensor in operative communication with a primary power equipment unit driving a transmission of a work vehicle generates a torque signal representative of torque delivered to the transmission by the primary power equipment unit. The overload protection method and system uses the torque signal to control the torque delivered to the transmission of a work vehicle by the primary power equipment unit.

  • Patent number: 11376954
    Abstract: A method for shifting a PTO transmission includes selecting a PTO output speed from one of a first PTO speed and a second PTO speed of the PTO transmission, operating the PTO transmission in a reduced power mode at the selected PTO speed, the reduced power mode providing lower power to the PTO transmission at the selected PTO speed than a normal operating mode, comparing an instantaneous drive power to a maximum drive power in the reduced power mode, and when the instantaneous drive power exceeds the maximum drive power, automatically shifting the PTO transmission under load from the reduced power mode to the normal operating mode and automatically adjusting a transmission ratio of a vehicle transmission.

  • Patent number: 11365792
    Abstract: A power split transmission structure has at least three interfaces to direct driving power from a drive to at least one output in order to supply the driving power to connected consumers. It comprises at least two variator paths which each comprise a summation gearbox communicating with an electric or hydraulic machine via a mechanical and a non-mechanical path in order to modify torque, speed or both of the driving power. A control device regulates the summation gearbox of each of the variator paths. A power electronics system or hydraulic control device is connected to the electric or hydraulic machine of each of the variator paths. The transmission structure directs the driving power via the variator paths such that the electric or hydraulic machine of each variator path is operable in a generator or motor mode in order to compensate for a power shortfall or a power oversupply at at least one outlet of the transmission structure.

  • Publication number: 20220074483
    Abstract: An oil management system for a vehicle includes a differential housing, a transmission housing, a lubricant tank, a suction line, a lubricant pump, and an air suction pump. The transmission housing is connected to the differential housing in an air-tight manner, and a lubricant through-passage is defined between the transmission housing and the differential housing. The lubricant tank is provided in the differential housing and has a lubricant suction opening in a lower region. The lubricant pump conveys lubricant from the lubricant tank through the suction line and conducts the lubricant to the lubrication points in the differential housing and the transmission housing. The air suction pump pumps air from the lubricant tank into the transmission housing so that an excess air pressure is maintained in the transmission housing.

  • Publication number: 20210406246
    Abstract: Data Analytics Engines can be provided as a “black-boxed” abstraction to their “users.” This allows a user to mix and match analytical components if their input data matches the input requirement of the engine. Furthermore, by decoupling the Data Analytics Engine creation from the environment, a high degree of process automation, scalability, and improved maintainability can be achieved. As a result, Data Analytic engineers and Data Scientists can create reusable components for other scientists and business users, whereas the users need not know how the Engines are coded or the environment in which their engines will run, but only need to know the input schema of the data.

  • Patent number: 11196322
    Abstract: In a method for manufacturing an electric motor comprising a rotor and a stator a placeholder for a temperature sensor is inserted in the axial direction between a first coil layer and an adjacent second coil layer of a winding head such that the placeholder is situated in a gap-shaped recess extending between the first and the second coil layers, the first coil layer is then pressed onto a circumferential surface of the placeholder and onto the second coil layer and is plastically deformed such that a space between the lateral surfaces of the two coil layers and the circumferential surface of the placeholder is reduced, and a contact surface between the lateral surface of the first coil layer and the circumferential surface of the placeholder is enlarged. By removing the placeholder, a receiving chamber is subsequently formed in the winding head, into which a temperature sensor is then inserted.

  • Patent number: 11178044
    Abstract: A communication system includes data generation units that generate data and a plurality of data evaluation units physically separated from the data generation units and connected to the data generation units via a non-proprietary network. The data evaluation units evaluate data transmitted by the communication system, which includes a hardware abstraction layer that represents a data evaluation unit as a resource that includes a property “data transmission type.” The property “data transmission type” is “Streaming” or “Bulk Upload” or “Streaming, Bulk Upload”. The communication system reads the property “data transmission type” and accordingly transmits the generated data to the data evaluation unit in accordance with the read property “data transmission type”.
