Abstract (en)

[origin: WO2007138005A1] The invention relates to a transmission, in particular a rear axle transmission for transmitting a drive torque from one drive shaft (2) to two output shafts (3, 5) by means of a differential unit (15) and a continuously variable device (14) for influencing the distribution rate of the drive torque to the output shafts (3, 5), said device being activated by means of at least one motor (37). The differential unit (15) comprises a differential (17) and a differential cage (19) that is operatively connected to the drive shaft (2) and the device (14) for influencing the distribution rate of the drive torque has two torque vectoring units (35), each of which is assigned to an output shaft (3 and 5). According to the invention, an oil chamber (120) that surrounds the differential unit (16) and oil chambers (122, 124) that surround each torque vectoring unit (35) are designed as separately sealed oil chambers (120, 122, 124).
