Abstract

Föreliggande uppfinning hänför sig till en drivanordning (10) för att vid ett fordon (1) fördela varvtal mellan tvenne hjulaxlar (12a, 12b) medelst en differentialanordning (40) hos drivanordningen. Drivanordningen innefattar en medelst en motoranordning (20) driven drivaxel (26) anordnad att driva nämnda hjulaxlar (12a, 12b), och medel för att medelst en transmissionsenhet (70) åstadkomma drivmomentförändring hos nämnda hjulaxlars (12a, 12b) drivning. Nämnda differentialanordning (40) är anordnad att fördela varvtal mellan nämnda tvenne hjulaxlar (12a, 12b) via en differentialaxelkonfiguration (42) drivningsmässigt förbunden med nämnda hjulaxlars (12a, 12b) drivning. Nämnda differentialanordning (40) är härvid anordnad att åstadkomma fördelning utan så kallad självlåsning hos differentialanordningen (40), varvid, vid varvtalsförändring hos en av nämnda hjulaxlars (12a, 12b) drivning, varvtalet och härvid drivmomentet hos nämnda hjulaxlar (12a, 12b) är anordnat att fördelas lika hjulaxlarna (12a, 12b) emellan genom nämnda differentialanordnings verkan.(Fig. 2)The present invention relates to a drive device (10) for distributing speed between two wheel axles (12a, 12b) in a vehicle (1) by means of a differential device (40) of the drive device. The drive device comprises a drive shaft (26) driven by a motor device (20) arranged to drive said wheel axles (12a, 12b), and means for effecting a drive torque change of the drive of said wheel axles (12a, 12b) by means of a transmission unit (70). Said differential device (40) is arranged to distribute speed between said two wheel axles (12a, 12b) via a differential axle configuration (42) operatively connected to the drive of said wheel axles (12a, 12b). Said differential device (40) is in this case arranged to effect distribution without so-called self-locking of the differential device (40), wherein, in the event of a change in speed of one of said wheel axles (12a, 12b), the speed and the driving torque of said wheel axles (12a, 12b) are arranged to be distributed evenly between the wheel axles (12a, 12b) by the action of said differential device. (Fig. 2)
