Abstract: A drive unit for a drive train of an electrically drivable motor vehicle, in particular a hybrid motor vehicle, and to a drive assembly. The drive unit is for a drive train of an electrically drivable motor vehicle, and includes a first electric rotary machine for generator operation and a second electric rotary machine for drive motor operation, and a transmission. A rotor of the first electric rotary machine is for direct mechanical coupling to an output element of an internal combustion engine, and a rotor of the second electric rotary machine is or can be rotationally coupled to an input of the transmission, with no torque-transmitting connection being provided between the first electric rotary machine and the transmission.

Abstract: A drive train unit for a drive train of a motor vehicle includes an input component for introducing a torque, a torsion damper for damping rotational non-uniformities, an output component for outputting the torque, and an intermediate hub. The torsion damper is connected in a torque-transmitting manner to the input component. The torsion damper includes a main damper having a spring element, and a radial inner side. The output component is connected in a torque-transmitting manner to the torsion damper. The output component is arranged radially outside of the spring element. The intermediate hub connects the torsion damper to the output component on the radial inner side.

Abstract: The invention discloses a safety circuit for electrically operated devices, which turns on the device in question, based on its position and design, only if handling and posture by the operator is completely correct and proper and the circuit, moreover, is static and insensitive to outside influences due to the use of sensor switches.
