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.

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.

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.
