Abstract
A transmission device for a motor vehicle includes a final drive and a planetary gearset. The planetary gearset has a first transmission element formed by a first ring gear, which first transmission element has external teeth for introducing a drive torque, at least one second transmission element and at least one third transmission element, which is coupled to the final drive. The device also has a brake element for lockingly braking at least one of the transmission elements of the planetary gearset. The final drive is a planetary differential, which is arranged radially inside the planetary gearset and is arranged in a gearwheel level with the planetary gearset.
Claims11
A transmission device for a motor vehicle, the transmission device comprising:
- a final drive;
- a planetary gearset comprising
- at least one first transmission element formed by a first ring gear and external teeth configured to deliver a drive torque,
- at least one second transmission element, and
- at least one third transmission element coupled to the final drive;
- and
- at least one brake element configured to lock-brake at least one of the first, second, and third transmission elements of the planetary gearset, wherein the final drive is arranged radially inside the planetary gearset, and
- wherein the final drive is a planetary differential comprising a second ring gear, a second sun gear, and a second planet carrier and the final drive is arranged in a gearwheel plane with the planetary gearset.
An electric drivetrain, comprising:
- a transmission device, comprising
- a final drive;
- a planetary gearset comprising
- at least one first transmission element formed by a first ring gear and external teeth configured to deliver a drive torque,
- at least one second transmission element, and
- at least one third transmission element coupled to the final drive;
- and
- at least one brake element configured to lock-brake at least one of the first, second, and third transmission elements of the planetary gearset, wherein the final drive is arranged radially inside the planetary gearset, and
- wherein the final drive is a planetary differential comprising a second ring gear, a second sun gear, and a second planet carrier and the final drive is arranged in a gearwheel plane with the planetary gearset;
- and
- an electric motor, comprising an electric motor output gearwheel arranged coaxially to a rotor of the electric motor, that meshes with the external teeth of the first ring gear and that is arranged in the gearwheel plane with the planetary gearset and the final drive.
