    摘要: The invention relates to a clutch unit for a motor vehicle, comprising: a clutch, the clutch having an axially stationary, rotatable coupling element with an axially extending toothing, and an axially displaceable, rotatable mating element with an axially extending mating toothing, the mating element being displaceable into a first position and a second position; and a sensor unit, the sensor unit being disposed radially in relation to the axial extension of the toothing of the coupling element such that the sensor unit senses the toothing of the coupling element. When the mating element is in the first position and when it is in the second position, the sensor unit detects a sensor signal via which the rotational speed of the coupling element and the first position of the mating element, the second position of the mating element, or a position of the mating element between the first position and the second position can be determined. The invention also relates to a motor vehicle drive train comprising a clutch unit of this type.

    摘要: A handheld power tool includes a torque coupling adjustable by the operator, as well as a gear unit for transmitting a torque generated by a drive motor to a drive shaft. The gear unit is advantageously a planetary gear unit; the torque coupling being constructed in such a manner, that in response to slippage of the torque coupling, a coupling component follows a displacement path. The handheld power tool further includes a control unit and a sensor, the sensor monitoring the coupling component for a displacement and transmitting corresponding sensor signals to the control unit. The control unit is configured to control, in particular, switch off, the drive motor as a function of the sensor signals received. It is further provided that the control unit subject the received sensor signals to a plausibility check, in order to determine if actual slippage of the torque coupling is occurring.

    摘要: A temperature monitoring system and method of utilization thereof is provided that provides the freedom of direct temperature determination from a friction plate (often referred to as a disc) or clutch friction separator plate in a clutch friction pack. The temperature monitoring system includes a temperature sensor which is placed on the friction disc or friction separator plate. An induction coil is placed on the friction disc or friction separator plate which provides placement for the temperature sensor. A magnet is provided to provide a magnetic field for the induction coil in order to generate current to power the temperature sensor. An antenna may also be provided which allows the temperature electronic data to be transmitted to a remote receiver.

    摘要: The invention relates to a dog clutch (10) with an axially fixed coupling element (12) and an axially movable coupling element (14), in which the axially fixed coupling element (12) and the axially movable coupling element (14) are configured to be sleeve-shaped and are disposed coaxially to one another, in which the axially movable coupling element (14) is axially displaceable by means of a pressurizing medium-actuatable piston (22) to establish a positively locking connection with the axially fixed coupling element (12), in which the piston (22) is disposed in a longitudinally displaceable manner in a cylinder housing (20), which radially on the outside carries the axially movable coupling element (14), in which the piston (22) is connected to the axially movable coupling element (14) via a piston pin (26), and in which a pressurizing medium (40) can be supplied to the cylinder space (60) of the cylinder housing (20) via a supply duct (38), wherein, at one axial end, the piston (22) is permanently connected to a coaxially aligned sensor bolt (48) and, on a sensor section (52) in the area of its free, piston-remote axial end (78), the sensor bolt (48) is configured as a transmitter element for a position sensor (70).

    摘要: A power transmission interrupting device includes: an interrupting member that is restrained from rotating relative to the first rotating member, has engaging teeth engaging with a second rotating member, and is movable in an axial direction between a coupling position at which the engaging teeth engage with the second rotating member and an uncoupling position at which the engaging teeth do not engage with the second rotating member; and a moving mechanism that moves the interrupting member in the axial direction. The moving mechanism has an annular electromagnet, a yoke, and a moving member. The moving member has a cylindrical part facing an inner circumferential surface or an outer circumferential surface of the electromagnet, and an annular cover extending from one end of the cylindrical part in a radial direction and covering one of axial end faces of the electromagnet.

    摘要: A dog clutch having two clutch members provided with claws or teeth, one of which is movable, as well as a positioning device for engaging and disengaging the clutch by a positioning movement of the movable clutch member. In order to establish a proper engaging of the dog clutch, a sensor is arranged along the movement path of the movable clutch member, which detects the movement of the clutch member into the engaged state, while the clutch member is provided with an activating contour which, upon engaging the clutch, moves past the sensor, which is preferably an electromagnetic actuator for holding the movable clutch member in the disengaged state of the clutch.
