Clutch device

InactiveUS20070039796A1Reduce distanceDisadvantageous effects on the degree of utilizationFluid actuated clutchesFriction clutchesTorque transmissionTakeoff
A clutch device has a housing connected to a drive; a takeoff, which is mounted with freedom of rotation in the circumferential direction relative to the housing; and at least one friction clutch, which is mounted in the housing and which can be shifted between an engaged position and a released position. The clutch has clutch components including at least one pressure-exerting device and at least one clutch element which can be actuated by the pressure-exerting device, both the clutch element and the pressure-exerting device being able to shift position to a limited extent in the axial direction. The clutch element has at least one friction surface and a clutch hub in working connection with the takeoff. Beginning at a point of contact between the engaged position and the released position and continuing until the engaged position is reached, the torque of the drive can be transmitted via the housing and the friction clutch to the takeoff, whereas on the other side of the contact point and continuing until the released position, this torque transmission is suspended. A torque-building arrangement, which exerts force on the pressure-exerting device in the direction pointing away from the clutch element of the friction clutch, is assigned to the pressure-exerting device. This torque-building arrangement uses the pressure-exerting device as a first support element on one side and the clutch element as a second support element on the other side. On at least one of these support elements and / or on the torque-building arrangement, at least one flow passage is provided for the fluid which is present in a cooling space inside the housing in which the friction clutch is disposed.

Protection device in motor vehicles for protecting individuals

Protection devices in motor vehicles typically have a movable element, for example a roll bar (1) or a flap, which, in the initial state, is fixed in its position by a releasable holding device. In the event of a hazard, the movable element can be released under sensor control by a common pyrotechnic actuator (11) and can be deployed with the protection being activated. The protection device also has a means (8, 9) for locking the deployed, movable element. A driving pressure chamber (12, 15), which is fixed on the bodywork and in which a driving piston (2 with 13, 16) connected to the movable element is accommodated in a guided manner, is connected downstream of the pyrotechnic actuator (11). The protection device is designed with regard to the pyrotechnic release and erecting system in such a manner that, with as small a pyrotechnic charge as possible and a defined holding force which is not applied by additional holding elements, the movable element can obtain a very high kinetic energy even after just a few millimeters of extension travel. To accomplish this, a releasable connection is formed by a locally delimited, frictional and / or form-fitting and / or bonding direct connection (14) between the wall of the driving pressure chamber (12, 15) and the driving piston (2 with 13, 16). The direct connection has a releasable holding force which amounts to at least 300 N and at maximum 5000 N.
