  • Patent number: 9555672
    Abstract: A pressure control device for a vehicle tire inflating system is configured to receive compressed air via a ventilating inlet, activate at least one seal for sealing an air chamber between a stator and a rotor of a rotary feedthrough via a seal actuating outlet, and ventilate a tire at a ventilating outlet pressure via a ventilating outlet and the feedthrough. A control valve is pneumatically controllable by a control pressure, the ventilating outlet being ventilated at the outlet pressure by the control valve only when the control pressure is at least a defined minimum pressure. In response to pressure build-up at the ventilating inlet at least to the minimum pressure, the control pressure and the seal actuating pressure are built up for ventilating, but build-up of the control pressure is delayed with respect to the seal actuating pressure. Activation of a seal prior to ventilation of the ventilating outlet is possible without additional actuating channels.

  • Patent number: 9296389
    Abstract: A motor vehicle driven by an internal combustion engine is equipped with at least two auxiliary units and with an electric machine connected to a power source. The electric machine can be coupled to the auxiliary units by means of a dual clutch device. A control device can actuate the dual clutch device for coupling the auxiliary units to the electric machine according to preselected priorities. One or the other auxiliary unit, or all auxiliary units, or no auxiliary unit may be coupled to the electric machine.

  • Patent number: 9079623
    Abstract: A rear spoiler device for a vehicle that has a rear door includes an air guiding element configured to attach to a lateral rear zone of the vehicle. The air guiding element can be pivoted between a travel position for contour extension and aerodynamic air guidance with the rear door of the vehicle closed, and a position in which it is hinged inwards with the rear door open. To this end, the air guiding element can be received in a hinge of the rear door, and the rear spoiler device has a spring device that presses the air guiding element in the travel position against a counter-stop formed on the hinge, preferably, on a hinge plate fastened to the rear door.
