Abstract
A motor vehicle has a steerable first axle, a driveable second axle, an electric drive for driving the second axle, and a traction battery via which the electric drive can be provided with electrical energy stored in the traction battery. The electric drive has a housing, an electric motor, which has a stator and a rotor that can be rotated around a rotor axis relative to the stator and relative to the housing, and a first planetary gear set arranged coaxially with the rotor axis. The first planetary gear set has a first element, a second element, and a third element.
Claims14
A motor vehicle (10), comprising:
- a steerable first axle (12);
- a drivable second axle (20);
- an electric drive (26) for driving the second axle (20);
- and
- a traction battery (28), wherein the electric drive (26) is providable with electrical energy stored in the traction battery (28) via the traction battery (28);
- wherein the electric drive (26) has:
- a housing (28);
- an electric motor (30) which has a stator (32) and a rotor (34) that is rotatable around a rotor axis (38) relative to the stator (32) and relative to the housing (28);
- a first planetary gear set (42) arranged coaxially with the rotor axis (38), wherein the first planetary gear set (42) has a first element, a second element, and a third element;
- and
- a second planetary gear set (52) arranged coaxially with the rotor axis (38), wherein the second planetary gear set (52) has a fourth element, a fifth element, and a sixth element, wherein in an axial direction of the rotor (34), the electric motor (30), the first planetary gear set (42) and the second planetary gear set (52) are arranged one after the other in the following order:
- the electric motor (30), the first planetary gear set (42), and the second planetary gear set (52), and wherein the rotor axis (38) is arranged at a right angle to a longitudinal direction (22) of the motor vehicle (10);
- wherein:
- in the longitudinal direction (22) of the motor vehicle (20), the first axle (12), the traction battery (28), the second axle (20), and the electric drive (26) are arranged one after the other in the following order:
- the first axle (12), the traction battery (28), the second axle (20), and the electric drive (26);
- the housing (28) is rigidly attached to a frame (18) of the motor vehicle (10);
- the electric drive (26) has an angle drive (62);
- the motor vehicle (10) has a cardan shaft (64);
- one of the fourth, fifth, and sixth elements of the second planetary gear set (52) is couplable with an input gearwheel (66) of the angle drive (62) in a manner fixed against rotation;
- an output gearwheel (68) of the angle drive (62) is couplable with an input side (E) of the cardan shaft (64);
- and
- an output side (A) of the cardan shaft (64) is couplable with an axle gearbox (70) of the second axle (20).
