An electric axial flux machine having a stator with first and second stator elements arranged spaced apart axially from one another, and a rotor with a rotor body arranged on a rotor shaft, in the form of a disk and arranged axially between the first and second stator elements, the first and second stator elements being arranged movably in the axial direction in relation to the rotor body. An adjustment device is provided to adjust the first stator element and the second stator element in the axial direction in order to set an air gap. The adjustment device adjusts the first stator element and the second stator element in the axial direction depending on a torque which is to be transmitted via the rotor shaft and which generates a resulting supporting moment on the first stator element and on the second stator element.

Electric axial flux machine

An electric axial flow machine having a stator, a first rotor body arranged on a rotor shaft, a second rotor body arranged on the rotor shaft, and a displacement device arranged between the two rotor bodies and coupled thereto. The displacement device includes at least one spring device which acts on the first rotor body and the second rotor body against the magnetic attractive force between the rotor body and the stator. The spring device is configured such that a spring force characteristic is formed which runs above the magnetic force characteristic over the entire displacement path.

A magnetic clutch for actuating a disconnect clutch includes an axis of rotation, an axially fixed stator, an axially movable armature, a torque-axial force converter unit with an armature side and a bearing side, and a rotary brake. The axially movable armature is axially retainable on the stator by a magnetic force from a power supply. The torque-axial force converter unit acts in an antagonistic manner to the magnetic force to hold the armature at an axial distance from the stator. The rotary brake is for effecting a rotational speed difference between the armature side and the bearing side. Other aspects of the disclosure include a disconnect clutch for an internal combustion engine in a hybrid drive train, a hybrid drive train, and a method for controlled closing of the disconnect clutch.

An electric radial flow machine having a stator, a rotor body connected to a rotor shaft, and a spring element which applies a spring force to the rotor body in the axial direction such that in a first operating position, the rotor body is held in an axial position in which the overlap between opposing surfaces of the rotor body and the stator is less than 100%. A displacement device with first and second displacement elements generates an axial movement between the rotor body and the stator against the spring force using a torque produced between the rotor shaft and the rotor body so that in the event of a rotation of the first displacement element relative to the second displacement element or vice versa, the rotor body is pushed on the rotor shaft axially against the spring force.

Electrical radial flow machine and powertrain

An electric machine designed as a permanently excited synchronous machine, including a rotor with a rotor body arranged on a rotor shaft, a stator, and a displacement device that generates a relative axial movement between the rotor body and the stator based on a torque produced between the rotor shaft and the rotor body. The displacement device has first and second displacement elements and at least one rolling body arranged between the first and second displacement elements. The first displacement element is axially movable and rotatable to a limited degree on the rotor shaft, and the second displacement element is connected to the rotor shaft rotationally fixed. The displacement elements provide that upon rotation of the first displacement element relative to the second or vice versa, the rotor body is pushed on the rotor shaft axially against the spring force.

A hybrid module for a drive train of a motor vehicle includes an electrical machine, a dry friction clutch for coupling the electrical machine with the drive train, an input shaft arranged to be coupled to an internal combustion engine of the motor vehicle, and an output shaft arranged to be coupled to a vehicle transmission of the motor vehicle. The dry friction clutch is designed to lead away or secure wear debris of the dry friction clutch. The hybrid module may be arranged as a P2 hybrid module within the drive train between an internal combustion engine side of the motor vehicle and a vehicle transmission side of the motor vehicle. The dry friction clutch may be a dry multi-disk clutch.

A friction clutch for a drivetrain of a motor vehicle includes and input part, an output part, a spring device, a pressure pot, and a connecting means connecting the pressure pot to the inner-plate carrier. The input part includes an outer-plate carrier which is rotatable about an axis of rotation by a drive motor, and an outer plate rotationally fastened to the outer-plate carrier.

Disk for a friction clutch

A two-stage clutch for separable connection of an input shaft to at least one output shaft, having a clutch cover, a clutch basket and a plurality of partial clutches, the partial clutches being operated in series. A first partial clutch is a pilot clutch, which is actively operable. A second partial clutch is a main clutch, which is operable by the pilot clutch, an operating force for the main clutch being produced by a torque transmitted by a shaft. In this two-stage clutch, the clutch cover is firmly connectible to the clutch basket. With the two-stage clutch proposed here, high torques can be transmitted despite small external operating forces. At the same time, the construction and assembly are greatly simplified in spite of the considerable complexity of the two-stage clutch, and the two-stage clutch has a significantly reduced rotating mass.
