摘要： An actuator is used to longitudinally move a spline sleeve for controlling drive mode of a differential on an off-road vehicle. The actuator's motor rotates an eccentric knob through a drive train including intermediate gears and a worm gear. The eccentic knob is linked to the spline sleeve through a torsion spring carried on a pivot plate, with legs of the torsion spring pushing a slide block, transferring a moment provided by the eccentric knob into a linear slide force. The pivot plate and torsion spring are jointly mounted on the actuator housing by a hub, opposite the rotational axis of the eccentric knob from the slide block. The slide block includes a contact which completes a circuit through conductive pads on the actuator housing, so the position of the slide block can be directly sensed.

摘要： An active differential for the controlled distribution of a drive torque generated by a drive motor to two drive shafts includes a planetary gear train configured to couple the two drive shafts to a drive shaft of the drive motor, and a distributor motor including a distributor shaft. The distributor motor produces a torque, with a distribution of a drive torque to the two drive shafts being dependant on the torque produced by the distributor motor. The distributor shaft and the planetary gear train are coupled by a coupling device which only transmits a torque from the planetary gear train to the distributor shaft when a rotational speed difference between rotational speeds of the two output shafts exceeds a predetermined limit value and when a connection condition depending on an operating condition of the distributor motor is satisfied.

摘要： In a power transmission device for a vehicle, a boss portion of a clutch guide, which is an input-side rotation member of a clutch unit, includes: a spline portion spline-connected to a small-diameter portion at one end of a center shaft which is an input shaft; and a fitting portion that extends further from the spline portion in an axial direction to contact the outer circumference of a medium-diameter portion of the center shaft. A recess functioning as a torque fuse is formed in the medium-diameter portion of the center shaft corresponding to the fitting portion. When the center shaft is severed or disconnected at the recess, the medium-diameter portion of the severed cut center shaft can still remain within the fitting portion, so that appropriate centering can be secured and stable self-propulsion of the vehicle can be secured without unwanted misalignment of the axis of rotation of the clutch.

摘要： The invention relates to a multi-disc clutch lock having a differential housing in which a differential pinion between axle bevel wheels, disc sets between the axle bevel wheels and the differential housing is untwisted, but thrust rings are arranged such as to be axially movable. The multi-disc clutch lock comprises outer discs of the disc sets that are non-rotatably connected to the differential housing and inner discs that are non-rotatably connected to the axle bevel wheels. As a result, an introduced driving torque is transmitted via the differential pinion to the thrust rings in order to press the disc sets together with the axial forces produced under load on the oblique contact surface of the differential pinion. An axially movable thrust piece is arranged between at least one disc set and the differential housing in order to transmit a lifting movement initiated by an actuator to the disc set. According to a method according to the invention for operating such a multi-disc clutch lock, a multi-disc clutch lock is then applied to a disc set by an actuator, wherein the actuator is activated by a control device that has software which converts the signals coming from a vehicle CAN bus into a control signal for the actuator using a control logic.
