  • Publication number: 20240384774
    Abstract: Motor vehicle vibration damper with at least one damper cylinder at least partially filled with a liquid damping medium; a piston rod axially movable to the longitudinal extension axis (L) of the damper and sections of which project into the damper cylinder; a piston rod guide surrounding the piston rod in the peripheral direction and seals off the damper cylinder; a gas-impermeable, shape-changing gas pressure container located in a compensation chamber inside the damper cylinder; a filling channel connecting the interior of the gas pressure container to the external environment; and a non-return valve at least indirectly connected to the gas pressure container and closes or opens the filling channel depending on gas pressure difference. The non-return valve is inside a gas-impermeable non-return valve housing connected to the piston rod guide.

  • Publication number: 20240371080
    Abstract: The present invention relates to a method for calculating one or more isovists of a physical or extended reality environment, comprising the following steps: providing at least one electronic acquisition device configured to obtain a plurality of georeferenced data, such as time, position, orientation, and configured to take frames of the physical or extended reality environment; calculating a positioning parameter for each user, each positioning parameter being representative of a positioning point of a respective user in the physical or extended reality environment and being determined from the georeferenced position data acquired when said respective user uses the electronic acquisition device to take a frame of the physical or extended reality environment; calculating an aim parameter for each user, each aim parameter being representative of the direction of a respective frame of the physical or extended reality environment taken by a user at the respective positioning point and being calculated from the

  • Patent number: 6986289
    Abstract: Apparatus for detecting a parameter associated with the torque transmitted by a friction clutch, where the friction clutch has a clutch disk which is or can be connected for rotation in common to a power takeoff shaft. The apparatus includes a receiver area, which does not rotate with the clutch disk in the torque-transmitting state, and a code provided on the clutch disk. The code can be scanned by the receiver area and thus generates a sensor signal associated with transmitted torque.

  • Publication number: 20040163922
    Abstract: An actuating device, in particular for a vehicle clutch, comprising a cylinder, in which a piston executes, as a function of a supply of pressure medium, a working movement having a maximum working travel which is defined by a stop fixed in relation to the cylinder, a damping device being arranged between the stop and a working-travel limiting surface of the piston.

  • Publication number: 20040000199
    Abstract: Apparatus for detecting a parameter associated with the torque transmitted by a friction clutch, where the friction clutch has a clutch disk which is or can be connected for rotation in common to a power takeoff shaft. The apparatus includes a receiver area (58), which does not rotate with the clutch disk in the torque-transmitting state, and a code provided on the clutch disk. The which code can be scanned by the receiver area and thus generates a sensor signal associated with transmitted torque.

  • Patent number: 6540057
    Abstract: The actuation device includes a pressure medium force cylinder arrangement by means of which the friction clutch can be actuated via a release member. A measuring member of a measuring arrangement detecting an actual release is in tractive force driving engagement with an associated mating member whose position represents the actual release along a measurement path, which engagement is essentially free from play.

  • Patent number: 6234290
    Abstract: An actuating installation for a friction clutch arranged in the drive line between a drive unit and a transmission. The installation having an actuating arrangement for the actuation of the friction clutch and a clutch-pedal arrangement, which is connected to the actuating arrangement and has a clutch pedal, which, in a first operating state, is actuable according to a force-travel characteristic of a first type. The actuating installation has a signaling and/or protection device, which is in operative connection with or is operatively integrated in the clutch-pedal arrangement, so that, after the response of the signaling and/or protection device to a second operating state, the clutch pedal can be actuated only according to a force/travel characteristic of a second type, which differs significantly from the force/travel characteristic of the first type in order thus to indicate the second operating state.

  • Patent number: 6050382
    Abstract: A clutch disk having a load torsion oscillation damper and an idling torsion oscillation damper with friction device. At least a part of the idling friction device has an inner toothing for rotationally fixed and play-free engagement with an outer toothing of an inner hub which is designed to be extended in the axial direction with a reduced diameter.
