A drive arrangement for at least one auxiliary system of a motor vehicle, having an internal combustion engine, at least one supplementary motor, and a gear, is provided. The gear is a planetary gear which is operatively connected to the engine and the at least one supplementary motor each via a respective input shaft, and to the auxiliary system via an output shaft.

An electric conductor, in particular for connecting the starter relay and starter motor of a motor vehicle, includes an ignition device ( ), which is in thermal contact with the conductor ( ) and is intended, if a limit temperature is exceeded, for igniting and destroying the conductor ( ). The conductor ( ) includes one or more strands extending continuously between the ends ( ) of the conductor. The ignition device is disposed on the conductor ( ) so as to split apart these strands in the event of ignition.

The starter apparatus for an internal combustion engine includes a starter motor; an axially shiftable starting gear engageable with a ring gear of the internal combustion engine; a drive train for transferring rotary motion of a drive shaft of the starter motor to the starting gear, the drive train including a plurality of parts from the starting gear to the drive shaft; a free wheel clutch coupled with the drive shaft of the starter motor; and a shock absorber spring device for damping torque shocks between the starting gear and the drive shaft occurring on operation of the starter and located in the drive train between the starting gear and the drive shaft of the starter motor. According to the invention the shock absorber spring device is prestressed to provide a torque acting in a drive rotation direction equal to from 15 to 50% of the stall torque of the starter motor delivered to the starting gear and a ratio of the torsional rigidity of another drive train equal to the above drive train without the shock absorber spring device and at the stall torque to the torsional rigidity of the shock absorber spring device effective at the starting gear must be at least 4.

To provide a dynamo electric machine, for combination, preferably, with a centrifugal circulating pump, having a rotor which is at least part-spherical, the stator is formed of edge-wound strip material, in which the stator part is a continuous strip of L-shape deformed strip, with notches (9') cut into the L prior to deformation, the bending edge (15) of the L changing throughout the length of the strip, uniformly, with uniform change of the spacing of the notches so that, as the strip is wound over a part-spherical form which defines an air gap between the rotor and stator, the width of the teeth between adjacent notches (9') will increase to define continuous through-slots (9) for the windings, and the bending corner (15) likewise will change from a position near the root of the notches (9') to a position within the solid portion of the second leg (18) of the L. In assembly, the solid portion or second leg forms the return yoke for the stator magnetic circuit, and is located circumferentially about the axis of rotation of the motor, forming a stepped arrangement which, at least approximately, conforms to the part-spherical air gap.

Three rotors disposed in axial succession on a common shaft are mounted to cooperate with a common stator having an annular laminated core coaxial with the shaft on which a three-phase stator winding is wound. The rotors are of two kinds, the middle one being of one kind and the outer ones of the other kind. These two kinds of rotors are, namely, the laminated core kind having a short-circuited squirrel cage conductor system and the synchronous having shell-shaped or ring-shaped permanent magnets mounted on a soft iron yoke which is in turn carried by a pierced hub of nonmagnetizable material. The squirrel cage rotor or rotors provide high starting torque, and the synchronous rotors provide good synchronous torque and a synchronous nominal speed. When the synchronous rotor is in the middle, the stator core may be subdivided into three parts to facilitate cooling.

Combination synchronous and asynchronous electric motor

A combined on-board electric network generator and heater for vehicles, having mounted in its housing an armature which supports at least one alternating current coil and, more particularly, three-phase current coils. The combined generator-heater has a drum-shaped rotor, driven by the engine of the vehicle. The housing of this unit is closed and encloses the rotor as well as the armature and is formed with fluid ducts. Within the housing, a cooling-air circulation is maintained which streams over the coils and rotors and cools them, transferring heat to heat exchange elements which form part of the housing. A cooling fluid circulates in the ducts in a loop through input and output ports. The loop closes upon itself outside of the housing. The cooling fluid circulation recovers heat losses in the generator and makes the heat available for heating the passenger compartment of a vehicle. Additional heat can be transferred to the fluid by an electrically heated heat exchanger with heater elements (37) which are selectively energized by switches under voltage or temperature control.
