Abstract

The system includes oil accumulators on each side of the hydraulic pumps or motors, and a four-way valve for alternating between the inlet and outlet on one of the pumps or motors. The pumps are fitted on the gables of an electric motor gable, and their output shafts constitute those of the rotor. The arrangement therefore forms an assembly within the electric motor rotor, comprising electric motor, differential and equipment for changing the direction of rotation of the different shafts.

' _ - r.¿.,._,,, 4ao'ss2 Patenfikrav'_ - r.¿., ._ ,,, 4ao'ss2 Paten fi claim 1. l.Hydrauliak differential i en elmotor, kännetecknad av, 2 st hydraulpuep/ootorer sannankopplade på så sätt mekaniskt att vardera hydraulpunp/motorn är ansluten sed sitt ytterhölje till var sin gavel av rotorn inom statorn på en elnotor,och hydrauliskt på så sätt att låser man rotorn och vrider utgående axeln på ena hydraulpunp/motorn vrider sig den andra hydraulpump/motorns axel sig i motsatt riktning.1. Hydraulic differential in an electric motor, characterized by 2 hydraulic pumps / motors connected mechanically in such a way that each hydraulic pump / motor is connected to its outer casing to each end of the rotor within the stator on an electric motor, and hydraulically in this way If you lock the rotor and turn the output shaft on one hydraulic pump / motor, the other hydraulic pump / motor shaft turns in the opposite direction. 2.Anordning enligt krav l, k ä n n e t e c-k n a d a v. att det i hydraulsystenet ingår 2st oljeackumulatorer åtskilda av varsin hydraulpunp/notor för att koopensera för oljeläckage i systemet.Device according to claim 1, characterized in that the hydraulic system includes 2 oil accumulators, each separated by a hydraulic point / notch, to co-compensate for oil leakage in the system. 3.Anordning enligt krav 1, k ä n n e t e c k n a d a v, att det i hydraulsystoet ingår en hydraulisk ventil mellan in- och utloppen hydrauliskt till hydraulpump/motorerna på så sitt att skifta: in- och utloppen på en sida blir 2st olika rotationsriktningar tillgängliga på utgående axlarna på hydraulpump/motorerna när rotorn roterar. ,Device according to claim 1, characterized in that the hydraulic system includes a hydraulic valve between the inlets and outlets hydraulically to the hydraulic pump / motors so as to shift: the inlets and outlets on one side become 2 different directions of rotation available on the output shafts on the hydraulic pump / motors when the rotor rotates. ,
