摘要:
The invention relates to a mass balancing device for balancing free inertial forces and/or free moments of inertia of a reciprocating internal combustion engine (1). The mass balancing device comprises two balancer shafts (3, 4) rotating at the same rotational speed in opposite directions of rotation, and a transmission (5) arranged between the crankshaft (2) of the internal combustion engine and the balancer shafts. The transmission drives the balancer shafts at a transmission ratio of crankshaft rotational speed to the balancer shaft rotational speed that is non-uniform over the crankshaft angle such that the angular speed of the balancer shafts is at the maximum at the piston dead centres. The mass balancing device is intended to be configured for an internal combustion engine in multicylinder design and the mean value of the transmission ratio is intended to be 1:2.

The invention relates to an electrical drive unit for a motor vehicle, said drive unit comprising a wheel hub drive that drives a vehicle wheel. Said wheel hub drive has a sealing element which is affected by friction and by means of which the interior of the wheel hub drive is sealed off from the surroundings in an airtight manner. According to the invention, a ventilation device is provided by means of which a pressure difference between the prevailing air pressure in the interior of the wheel hub drive and the prevailing air pressure of the surrounding air can be compensated by displacing volumes of air.

A safety clutch for an electric drive which includes an electric motor and a shaft which is driven thereby. A transmission of torque between the electric motor and the shaft can be brought about by at least one connecting element. A controllable locking device via which an interruption in the transmission of torque between the electric motor and the shaft can be brought about, is assigned to the connecting element. The use of the safety clutch in an electric drive for a wheeled vehicle is disclosed, a controller evaluating the transmission of torque between the electric motor and the shaft using a vehicle state, and when a fault state is detected the controller transmitting a control signal to the controllable locking device, as a result of which an interruption is brought about in the transmission of torque between the electric motor and the shaft.

The invention relates to an electrical drive unit for a motor vehicle, said drive unit comprising a wheel-hub drive that drives a vehicle wheel and that is arranged on said vehicle wheel by means of a wheel bearing, said wheel-hub drive having a rotor and a stator. According to the invention, a sealing device is provided between the rotor and the stator, and/or between the rotor and a component adjacent to said rotor, and/or between the stator and a component adjacent to said stator. A sealing surface of said sealing device is arranged on a radius with the centre point around a virtual tilt axis of the wheel bearing, or substantially along a tangent to said radius.
