  • Patent number: 11396915
    Abstract: A method and an open-loop and closed-loop control device for compensating for a clutch torque of a separating clutch located between an internal combustion engine and an electric machine in a hybrid drive of a motor vehicle. The compensation takes into consideration the rotational speed of the electric machine. The rotational speed of the electric machine impacts clutch torque. A compensation factor is calculated, and increases or decreases the necessary clutch torque, causing a corresponding actuation of an actuator to achieve the necessary clutch torque.

  • Patent number: 11365773
    Abstract: A multi-disc brake includes an annular brake coil holder with a wound brake coil, an armature plate with a disc support to which a multiplicity of armature plate discs is fastened. A compression spring brings about a linear spacing of the brake coil holder from the armature plate made of a ferromagnetic material in a braking position of the multi-disc brake and, when current is applied to the brake coil, a released position of the multi-disc brake can be created by attracting the armature plate in the direction of the brake coil holder. The braking effect results from the interaction of the armature plate discs with drive shaft discs on a drive shaft. The brake coil holder area of the brake coil holder and the cross-sectional area of the brake coil are substantially of rectangular single-legged design, and when installing the multi-disc brake, part of the wall of the drive support surrounds the brake coil on two sides and the brake coil holder on one side.

  • Patent number: 11333210
    Abstract: An electromagnetic clutch (1) of an air conditioning compressor (2), in particular for a motor vehicle (11), transmits a torque to a drive shaft (3) of the compressor (2) depending on an electric current (I) being fed to clutch coils (4) of the electromagnetic clutch (1) to generate an electromagnetic clutch force. According to a control method (10), a slippage of the electromagnetic clutch (1) is determined by a difference between the rpms of the electromagnetic clutch (1) and of the drive shaft (3), and is monitored by a slippage sensor (5). The electric current (I) and the resulting clutch force are adjusted dependent on slippage by a pulse width modulation controller (6) of the compressor (2). The pulse width modulation controller (6) is electrically connected to the clutch coils (4) and modulates a pulse width of the electric current (I) fed to the clutch coils (4).
