  • Publication number: 20250122911
    Abstract: An electromagnetically actuated dog clutch includes a shifting sleeve which has an internal toothing and is received axially movably on an external toothing of a transmission shaft for joint rotation therewith, an actuator which has a magnet coil and is configured so as to be adapted to move the shifting sleeve axially on the transmission shaft into a first shifting position, a spring element which cooperates with the shifting sleeve and acts upon the shifting sleeve in a direction opposite to a movement caused by the actuator in the direction of a second shifting position, and a support ring which is plugged onto the transmission shaft and is arranged in an axial direction of the shifting sleeve between the spring element and the internal toothing of the shifting sleeve. The support ring is firmly connected to the transmission shaft with respect to the axial direction.

  • Publication number: 20240376941
    Abstract: The present disclosure relates to an electromagnetic clutch, including a selector sleeve which is arranged in a rotationally fixed manner on a first shaft and is adapted to be shifted linearly along the first shaft between an engaged and a disengaged state, a coupling body which is aligned coaxially to the first shaft, a stator which has a coil which serves to shift an armature ring linearly along the first shaft, the armature ring being mounted radially in an axial guide separately from the first shaft and the coupling body, wherein a shifting of the armature ring by the coil is also accompanied by a shifting of the selector sleeve. The present disclosure also relates to a method of closing and opening an electromagnetic clutch.

  • Publication number: 20240352979
    Abstract: 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.

  • Publication number: 20230133619
    Abstract: 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.

  • Publication number: 20230140319
    Abstract: 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.

  • Publication number: 20180266493
    Abstract: 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.

  • Publication number: 20180038420
    Abstract: 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.
