Claim:
An apparatus ( 8 ) for adjusting a power transfer capability of two frictional shifting elements (k_HA_L, k_HA_R), which conduct an output torque of a transmission ( 3 , 9 ) of a vehicle in a direction transverse to a longitudinal axis of the vehicle, to driving wheels ( 5 A, 5 B) of a drivable vehicle axle ( 5 ), the apparatus comprising: a first shifting element (k_HA_L) and a second shifting element (k_HA_R) for apportioning a power transfer capability from the transmission to the driving wheels ( 5 A, 5 B), the first shifting element (k_HA_L) having an electric motor ( 10 A) operationally connected to a first transmission apparatus ( 11 A), and the second shifting element (k_HA_R) having an electric motor ( 10 B) operationally connected to a second transmission apparatus ( 11 B); a first drive converter apparatus ( 12 A) located between the first shifting element (k_HA_L) and the first transmission apparatus ( 11 A), and the first drive converter apparatus ( 12 A) transforming rotationally directed drive from the electric motor ( 10 A) of the first shifting element (k_HA_L) into a translational activation motion for controlling the first shifting element (k_HA_L); a second drive converter apparatus ( 12 B) located between the second shifting element (k_HA_R) and the second transmission apparatus ( 11 B) of the second shifting element (k_HA_R), and the second drive converter apparatus ( 12 B) transforming a rotationally directed drive from the electric motor ( 10 B) of the second shifting element (k_HA_R) into a translational activation motion for controlling the second shifting element (k_HA_R); and a drive element ( 14 A, 15 A)of the first drive converter apparatus ( 12 A) and a drive element ( 14 B, 15 B) of the second drive converter apparatus ( 12 B), a first portion ( 14 B) of the drive element ( 14 B, 15 B) of the second drive converter apparatus ( 12 B) and a first portion ( 15 A) of the drive element ( 14 A, 15 A) of the first drive converter apparatus ( 12 A) are translationally movable while second portion ( 14 A) of the drive element ( 14 A, 15 A) of the first drive converter apparatus ( 12 A) and a second portion ( 15 B) of the drive element ( 14 B, 15 B) of the second drive converter apparatus ( 12 B) are axially fixed; the two frictional shifting elements (k_HA_L, kHA_R)are directly axially adjacent and share a common disk carrier ( 16 ); and the second portion ( 14 A) of the drive element ( 14 A, 15 A) of the first drive converter apparatus( 12 A) is driven by the electric motor ( 10 A) of the first transmission apparatus ( 11 A), and the first portion ( 14 B) of the drive element ( 14 B, 15 B) of the second drive converter apparatus ( 12 B) is driven by the electric motor ( 10 B) of the second transmission apparatus ( 11 B).
