CLASS INTERNATIONAL SWEDISH H 02 j21 di: 18 PATENT AND REGISTERS OF THE SWEDISH Ans. 732411963 was received on 2/7 1963 issued on 9/8 1964 C-0 LINDBERG, STOCKHOLM Device for electric motors The present invention relates to a. device for electric motors and has the purpose of providing a drive of two working means with different or inboard varying speeds but with substantially equal torques. Such conditions exist, for example, in the driving of vehicle wheels, such as car wheels, but also in other devices where planetary shafts are used. However, a planetary gear has the disadvantage that the speeds of the output shafts are mechanically boarded in determined if the driving resistance of one member ceases the torque of the other member ceases. Delta is particularly gallic when driving in slippery conditions. In some cases, the problem has been mechanically loaded by the introduction of an additional coupling for connecting the output shafts of the differential shaft, which meant weighting and costing for the car. Corresponding malfunctions occurred on other machines equipped with differential or planetary shafts.

Enligt uppfinningen undatn5jas dessa nackdelar darigenom att den elektriska motorn är utrustad med tva i ett gemensamt falt och koaxiellt i varandras fOrlangning roterhart lagrade rotorer kopplade till var silt am namnda arbetsorgan, vilka kopplingsmassigt aro helt frista.ende fran varandra. According to the invention, these disadvantages are exempted from the fact that the electric motor is equipped with two rotors mounted in a common field and coaxially rotatably rotatably connected to each other in the said working means, which are completely independent of each other in terms of coupling.

Motorn kan vara utford sasom likstrOmseller vaxelstromsmotor samt vara reglerad ph Mitt satt. Genom uppdelning av statorns lindning kan en okad kombination am kopplingsmojligheter och darmed storre manovreringsformaga ernas. FOr omstallning av rotationsriktning kan en. gemensam anordning for de hada rotorerna anvandas. The motor can be challenged as a DC or AC motor and be regulated ph Mitt satt. By dividing the winding of the stator, an increased combination of coupling possibilities and thus larger maneuvering capabilities can be achieved. For conversion of direction of rotation, one can. common device for the hada rotors is used.

Rotorernas koaxiella lagring kan ske pa aka satt med eller utan stod-vagg mellan rotorerna i statorn. The coaxial storage of the rotors can take place either with or without a stand cradle between the rotors in the stator.

I det foljande beskrives en utforingsform Dupl. ki. 63 c: 1/08 am uppfinningen med hinvisning till bifogade sehematiska ritning. In the following, an embodiment Dupl. ki. 63 c: 1/08 am invention with reference to the attached sehematic drawing.

Pa ritningen betecknar 1 en stator for vaxel- eller likstrom, som ph vanligt salt Or anhragt i ett statorhus 2 med lagerskoldar 3. Statorn. 1 antages i det visade exempkt vara anordnad for likstromsdrift men kan lika val vara avsedd for vaxelstrom, sasom enfas- eller trefas drift. In the drawing, 1 denotes a stator for alternating current or direct current, which is ordinary salt Or placed in a stator housing 2 with bearing shields 3. The stator. 1 is assumed in the example shown to be arranged for direct current operation, but equal choices can be intended for alternating current, such as single-phase or three-phase operation.

I del visade exemplet aro tva separata rotorer 4 och 5 lagrade pa var sin axet 6 och 7, vilka senare am forsedda med kommutatorer 8 och 9. Falt- och ankarlindningarna kunna vara kopplade pa onskat salt for att svara mot farekommande driftsf5rha11anden samt vara styrda am lampliga i och for sig kanda kontroller. Harvid kan faltlindningen avert vara uppdelad for alt giva storre variationsmojligheter. In part, the example showed that two separate rotors 4 and 5 are each mounted on the axis 6 and 7, which are later provided with commutators 8 and 9. The fold and anchor windings can be connected to the desired salt to respond to hazardous operating conditions and be controlled by appropriate per se kanda controls. In this case, the field winding can be divided to give greater possibilities for variation.

De koaxiella axlarna 6 och 7 aro i det visade exemplet vid sina mot varandra vanda andar lagrade i ett gemensamt lager 10, som lampligen uppbares ay mot statorhuset 2 stiidande ekrar 11. Emellertid kunna dessa lagerandar vara lagrade pa annat satt, exempelvis med i varandra ingripande delar, varvid ytterlagren vid lagerskoldarna 3 aro anordnade att upptaga bojmoment pa axeln och styra axlarna 6, 7 i deras koaxiella lagen. The coaxial shafts 6 and 7 are in the example shown with their facing spirits stored in a common bearing 10, which is suitably supported by the spokes 11 supporting the stator housing 2. However, these bearing ends can be stored in another way, for example with interlocking parts, the outer bearings at the bearing shields 3 being arranged to absorb bending moments on the shaft and guide the shafts 6, 7 in their coaxial bearings.

Vid drift komma saledes de hada rotorerna att drivas med i huvudsak samma vridmomeat vid ungefar samma varvtal men att yid &at motstand ph hada eller endera vridmomentet kommer att ph kant satt okas. Om ettdera arbetsorganet, sasom ett hilhjul, fOrlora sitt motstand kommer detta icke, sasom vid planetvaxlar att medfora ett upphavande av driften pa det andra arbetsorganet, som hibehaller sin drivfOrmaga oforandrad. During operation, the rotors had to be driven with essentially the same torque at approximately the same speed, but if the resistance had or either torque would be increased. If one of the working members, such as a gear wheel, loses its resistance, this will not, as in the case of planetary shafts, lead to a cessation of the operation of the other working member, which maintains its driving force unchanged.

Ehuru beskrivningen behandlat likstromsmaskiner kan uppfinningen givetvis tillampas pa. vilket annat drivsatt som heist, sasorn 2— — enfasdrift, trefasdrift med kortslutna eller slapringade rotorer osv. Although the description relates to DC machines, the invention can of course be applied to. what else is driven as a hoist, sasorn 2— - single-phase operation, three-phase operation with short-circuited or slack-rotating rotors, etc.

Claims

Patent claim:

Device for electric motors preferably for driving two working means with different or inboard varying speeds with substantially equal or varying torques, such as for example the wheels of a pair of wheels for cars or other vehicles, characterized by two in a common field (1) and coaxially rotatably mounted rotors (4, 5) coupled to each other by said operating means, which coupling members are apparently completely free from each other.

Device according to claim 1, may be networked by switching means common to the wide rotors (4, 5), for example for switching brushes at commutator motors.

Device according to claim 1, characterized in that the stator or field winding is divided, for example, into sections for increased control possibility. Request publications: Patentslerifter frein Danmark 25 547; Germany 925 570, 967 735.
