  • Patent number: 11454226
    Abstract: A pumping system for fracking fluid is designed to provide nearly constant flow rate. The pumping system includes a set of linear actuator pumping units, each driven by an electric motor. Each pumping unit includes a first set of pumping chambers that expel fluid when the linear actuator is moving in a first direction and a second set of pumping chambers that expel fluid when the linear actuator is moving in an opposite direction. The speeds of the actuators are coordinated such that a total flow rate of the pumping system is substantially constant.

    Abstract: A torsional vibration damper for a clutch disk within a drive train of a motor vehicle includes an input part arranged around an axis of rotation (d), a spring device with at least three spring elements, an output part, and torque-transmitting intermediate elements. The output part can be rotated relative to the input part about the axis of rotation (d) to a limited extent against the spring device. The torque-transmitting intermediate elements are arranged between the input part and the output part for forcible radial displacement by means of cam mechanisms when the input part rotates relative to the output part. The spring device is arranged between the torque-transmitting intermediate elements, and a number of intermediate elements corresponds to a number of spring elements.

  • Publication number: 20220299071
    Abstract: A method and an open-loop and closed-loop control device for compensating for a clutch torque of a separating clutch located between an internal combustion engine and an electric machine in a hybrid drive of a motor vehicle. The compensation takes into consideration the rotational speed of the electric machine. The rotational speed of the electric machine impacts clutch torque. A compensation factor is calculated, and increases or decreases the necessary clutch torque, causing a corresponding actuation of an actuator to achieve the necessary clutch torque.
