Abstract: A centrifugal clutch includes an input part, an output part, a centrifugally engageable and disengageable friction unit, and a shifting apparatus. The friction unit has first frictional elements connected to the input part, and second frictional elements connected to the output part and layered alternately with the first frictional elements. The shifting apparatus is for frictionally engaging the first frictional elements and the second frictional elements to engage the clutch. The shifting apparatus has a centrifugal mass and a brake spring. When the centrifugal mass moves from a disengaged position to an engaged position, the brake spring is arranged to apply a first braking force contrary to a first direction of motion of the centrifugal mass. The brake spring is also arranged to apply a second braking force contrary to a second direction of motion of the centrifugal mass. The first braking force is greater than the second braking force.

Abstract: A structurally and/or functionally improved friction clutch device is disclosed. In particular, a servo spring for a clutch is to be provided which is suitable for series production. In particular, the servo spring is to be realized in the clutch while integrating already existing components. In particular, the servo spring is to keep a maximum disengaging force low. In particular, the servo spring is to operate only under worn conditions; in the new state and during separation it should be possible for it to be force-free. In particular, the total tolerance in the friction clutch device is to remain small, so that the susceptibility of the servo spring force to tolerance deviations is limited.

Abstract: A friction clutch for a drivetrain includes an input shaft, an output shaft, a compressible friction pack including a normally closed spring system, and an actuating device. The compressible friction pack is for transmitting a torque between the input shaft and the output shaft in a closed state of the friction clutch. The actuating device is for producing an axial actuating force to compress the compressible friction pack. The actuating device includes an opening spring for exerting an opening force, a centrifugal mass unit including a ramp, and a switching element including a counterpart ramp. The centrifugal mass unit is movable through a radial travel at a predetermined rotational speed of the input shaft. The ramp and the counterpart ramp form a ramp pairing with a ramp gradient to convert the radial travel into the axial actuating force acting counter to the opening force to compress the compressible friction pack.

Abstract: A centrifugal clutch for a drive train of a motor vehicle includes an input part, an output part, a friction unit, a counterpressure plate, a shifting device, and a snap ring. The output part is arranged coaxially and rotatably in relation to the input part and includes a leaf-spring core with a fixing element. The friction unit includes first friction elements connected to the input part and second friction elements connected to the leaf-spring core. The second friction units are arranged in alternate layers with the first friction elements in an axial direction. The shifting device is arranged to clamp the first friction elements and the second frictional elements against the counterpressure plate for frictional engagement in response to a centrifugal force. The fixing element extends through the counterpressure plate. The counterpressure plate is fixed to the fixing element by the snap ring.

Abstract: A centrifugal clutch (1) is provided for a drive train of a motor vehicle, having a motor-driven torque input component (2) and a downstream first clutch element (3) which has at least one first centrifugal mass (4) which can be displaced radially to transmit torque in order to move into a non-positive connection with a transmission-side torque output component (5) when in the displaced state. A second clutch element (6) having a second centrifugal mass (7), which can be displaced radially into a non-positive connection with an intermediate component (8) when in the displaced state to transmit torque, is connected in series with the first clutch element in the torque path.

Abstract: A centrifugal clutch includes an angle plate, an inner basket, a pre-stressing element, and a coupling pin. The angle plate has an elongated hole and a loading section with a first side. The coupling pin is inserted into the elongated hole. A pre-stressing element stop is attached to the pre-stressing element and a coupling pin stop is attached to the coupling pin. The coupling pin is arranged to at least partially transmit axial movement of the angle plate to the inner basket. In an intermediate operating position, a relative movement between the angle plate and the coupling pin is possible when the inner basket rotates relative to the angle plate, and the coupling pin stop is matched to the pre-stressing element stop and the loading section so that the first side of the loading section has a maximum contact area to transmit a force to the pre-stressing element.
