An apparatus for additively manufacturing a heterogeneous structure () using a plastic fiber () and an energy transfer material () is disclosed. Additive manufacturing is performed in a vertical direction (z) perpendicular to a horizontal plane (x-y). The apparatus comprises: a nozzle device () adapted to provide the plastic fiber () for additive manufacturing; a feeding device () adapted to move the energy transfer material () back and forth in a vertical direction (z); and moving device () adapted to independently move (or rotate) the feeding device () and the nozzle device () in the horizontal plane (x-y) to fabricate the heterogeneous structure () in the horizontal plane (x-y).

The invention relates to a parking brake for a motor vehicle, including a pivotable locking mechanism for applying a retaining force to a parking brake gear. The locking mechanism can lock into the parking brake gear by means of an axially movable first actuation unit. According to the invention, the first actuation unit is designed as a spring-loaded cam follower. The invention also relates to an operating method for locking and unlocking the parking brake.

Parking brake and operating method

A rotating electric machine includes a stator having a winding head at each axial end and including a rotor, which is rotatably mounted in an opening in the stator and which has a rotor shaft and a laminated rotor core. The electric machine includes a bearing unit for the rotatable mounting of the rotor shaft with respect to the laminated rotor core, a transmission unit, a coupling unit, which is designed to provide at least two coupling states for coupling the rotation of the rotor shaft to the laminated rotor core and, in at least one of the coupling states, to couple the rotor shaft to the laminated rotor core by means of the transmission unit.

A manual gearbox section for a vehicle includes a section input, a section output, a freewheel device situated in a freewheel torque path between the section input and the section output, and a clutch device situated in a clutch torque path between the section input and the section output. The clutch torque path forms a bypass path with respect to the freewheel device and/or the freewheel torque path. The freewheel device is in the form of a rotational-speed-dependent freewheel device. The freewheel device is in a freewheeling state at a first rotational speed and in a coupled state at a second rotational speed. The second rotational speed is higher than the first rotational speed.

A method for determining the position of a first actuating element of an electrical parking lock device of a motor vehicle, wherein the first actuating element is mounted on a spindle in an axially mobile manner, where the method includes a step in which the first actuating element is moved in an opening direction to a stop, the spindle is then rotated to move the first actuating element in a closing direction, the current input and the energy consumption of a driver are captured at this point, provision is then made for identifying a first reference point if the current input of the spindle drive increases or decreases by at least a first threshold value, the first reference point is assigned to the energy consumption that has been captured, where the first reference point corresponds to the first actuating element coming into contact with an actuating pawl.
