1. A transmission (1) for a motor vehicle (100), comprising:
a first planetary gear set (P1), a second planetary gear set (P2), and a third planetary gear set (P3), each of the first, second, and third planetary gear set (P1, P2, P3) respectively comprising a first element (E11, E21, E31), a second element (E12, E22, E32) and a third element (E13, E23, E33);
an input shaft (WAn) configured for connecting the transmission (1) to a prime mover (2) of the motor vehicle (100);
a first output shaft (WAb1) and a second output shaft (WAb2) configured for connecting the transmission (1) to a respective wheel (R1, R2) of the motor vehicle (100); and
a first coupling shaft (W1) and a second coupling shaft (W2) configured for connecting two elements of two of the first, second, and third planetary gear sets (P1, P2, P3) for conjoint rotation,
wherein the transmission is configured such that a speed differential is implementable between the first and second output shaft (WAb1, WAb2), and the transmission is not configured for torque vectoring between the first and second output shaft (WAb1, WAb2),
wherein one of the first, second, and thirds elements (E11, E21, E31) of the first planetary gear set (P1) is rotationally fixed to the input shaft (WAn), another of the first, second, and thirds elements (E11, E21, E31) of the first planetary gear set (P1) is rotationally fixed to the first coupling shaft (W1), and another of the first, second, and thirds elements (E11, E21, E31) of the first planetary gear set (P1) is rotationally fixed to the second coupling shaft (W2),
wherein one of the first, second, and thirds elements (E12, E22, E32) of the second planetary gear set (P2) is rotationally fixed to the first coupling shaft (W1), another of the first, second, and thirds elements (E12, E22, E32) of the second planetary gear set (P2) is rotationally fixed to a stationary component, and another of the first, second, and thirds elements (E12, E22, E32) of the second planetary gear set (P2) is rotationally fixed to the second output shaft (WAb2), and
wherein one of the first, second, and thirds elements (E13, E23, E33) of the third planetary gear set (P3) is rotationally fixed to the second coupling shaft (W2), another of the first, second, and thirds elements (E13, E23, E33) of the third planetary gear set (P3) is rotationally fixed to the first output shaft (WAb1), and another of the first, second, and thirds elements (E13, E23, E33) of the third planetary gear set (P3) is rotationally fixed to the second output shaft (WAb2).
