摘要： A multi-plate clutch is disclosed, including an outer plate carrier, an inner plate carrier, and a set of plates of alternately arranged radially between the outer plate carrier and the inner plate carrier and which is delimited by two end plates engaging at opposite ends of the set of plates, wherein each end plate rests against an annular axial supporting contour on the end face facing away from the set of plates, wherein the supporting contours differ in their effective diameter at which the supporting contours contact the associated end plate, and wherein the supporting contours apply an axial force on the set of plates such that the plates are elastically deformed into a conical shape.

摘要： The invention relates to a gear shift device for a motor vehicle transmission, comprising a first and a second gearbox component which are rotatable relative to each other around a gearbox axis, a friction ring which is connected to the first gearbox component comprising a conical frictional surface, a plurality of first disks and a plurality of second disks. The first and second disks form a multi-disk clutch, the first disks being coupled to a synchronization element in a rotationally fixed manner, and the synchronization element comprising, axially adjoining the conical frictional surface of the friction ring, a conical mating surface for speed synchronization between the first gearbox component and the first disks. Further, the first disks are designed as a synchronization disk where the synchronization element is integrally formed thereon and/or one of the first disks is designed as a disk support coupling all first disks in the circumferential direction in a form-locking manner.

摘要： In a claw-type gearshift, a blocking ring is arranged axially between a hub body having a sliding sleeve and a clutch body such that it is rotatable between a release position and two locking positions. The blocking ring is adapted to be displaced toward the clutch body until conical friction surfaces on the blocking ring and on the clutch body come into contact. The blocking ring constitutes a form-locking blockade for the sliding sleeve against displacement of the sliding sleeve teeth between the clutch body teeth when an axial shifting force is applied in the non-synchronized state. When the claw clutch is shifted, a difference in speed between the clutch body and the hub body is reduced and the sliding sleeve is deflected in the axial direction toward the speed change gear to be shifted, as a result of which a friction surface of the blocking ring and a mating friction surface of the clutch body come into contact.

摘要： A shifting device for a motor vehicle is described, comprising a first coupling component which is adapted to be selectively rotationally coupled to a second coupling component with a form-fit. In an open state, the first coupling component is rotationally decoupled from the second coupling component. In a frictional fit state, the coupling components are rotationally coupled with a frictional fit via a first frictional fit ring and a second frictional fit ring. In a form-fit state, an actuating ring is rotationally coupled to the first coupling component and the second coupling component with a form-fit such that the latter are connected with a form-fit. A motor vehicle transmission, in particular a fully automatic stepped transmission having such a shifting device is additionally presented.

摘要： The present disclosure relates to an electromagnetic clutch including a shifting sleeve which has a first toothing, is arranged in a rotationally fixed manner on a first shaft and can be displaced linearly along the first shaft between an engaged and a disengaged state, a first clutch body, which has a second toothing and which is aligned coaxially to the first shaft, the first and/or the second toothing having undercuts in the direction of the engaged state, which are configured such that a torque transmission between the first shaft and the first clutch body generates a force on the shifting sleeve in the direction of the engaged state. The present disclosure also relates to a method of closing and opening an electromagnetic clutch.

When the claw clutch is shifted, a difference in speed between the clutch body and the hub body is reduced and the sliding sleeve is deflected in the axial direction toward the speed change gear to be shifted, causing a friction surface of the blocking ring and a mating friction surface of the clutch body to come into contact. The blocking ring switches over in the circumferential direction into one of two possible locking positions, locking the sliding sleeve.

摘要： A synchronizer unit for a manual transmission, in particular of a motor vehicle, has a hub which is adapted to be connected to a gear shaft for joint rotation therewith and includes a circumferentially continuous external toothing, a sliding sleeve which is received on the external toothing of the hub for displacement in the axial direction, but so as to be coupled in the circumferential direction to prevent relative rotation, at least one synchronizer ring which includes a preferably cone-shaped friction surface for friction coupling of the synchronizer ring to a speed change gear of the manual transmission and is adapted to be actuated by the sliding sleeve, and a spring ring which is arranged at an axial side of the external toothing of the hub and is configured to lock the sliding sleeve in a neutral position. The spring ring rests against a face side of the sliding sleeve and being operatively arranged between the sliding sleeve and the synchronizer ring.

摘要： A claw-type gearshift has a sliding sleeve which is adapted to be axially displaced on a hub body and a clutch body of a speed change gear. The hub body has at least one thrust piece arranged thereon which includes a friction surface that cooperates with a mating friction surface on the clutch body, the at least one thrust piece being displaceable in the circumferential direction between a release position and two locking positions that are located on either side of the release position. A first locking structure on the at least one thrust piece cooperates with a second locking structure on the internal toothing of the sliding sleeve. The locking structures are configured such that in each of the locking positions, the locking structures rest against each other such that a further axial movement of the sliding sleeve is blocked. For shifting a gear, a difference in speed between the clutch body and the hub body is reduced.

摘要： A claw-type gearshift includes a sliding sleeve and a clutch body of a speed change gear, in which the sliding sleeve can engage. A blocking ring having an external toothing is arranged axially between the hub body and the clutch body and is fixed to the hub body such that it is rotatable in relation to the sliding sleeve by a certain degree in the circumferential direction between a release position and two locking positions. The blocking ring has a plurality of axially resilient tabs which are directed radially inward and which bear against the hub body and limit the movement of the blocking ring relative to the hub body in the circumferential direction, and a ring portion which is arranged radially outside of the tabs and which includes a friction surface that rests permanently against a mating friction surface on the clutch body.
