Abstract
A differential drive device for a transmission system for a motor vehicle, having an axis of rotation (X) includes a planet carrier supporting engagement toothing, notably axial engagement toothing. An output ring gear is rotatable about the axis of rotation and supporting engagement toothing, notably radial engagement toothing. An axially movable blocking sliding gear is provided with engagement toothing, notably radial engagement toothing, and an axially movable connection sliding gear is provided with engagement toothing, notably axial engagement toothing. The connection sliding gear and the blocking sliding gear are movable in order to assume three axial positions: a disconnected position, a connected position, and a blocked position.

A differential drive device for a transmission system for a motor vehicle, having an axis of rotation and comprising:
- a planet carrier supporting engagement toothing;
- planet gears rotatably mounted on the planet carrier;
- an output ring gear meshing with the planet gears and rotatable about the axis of rotation and supporting engagement toothing;
- an axially movable blocking sliding gear provided with engagement toothing;
- an axially movable connection sliding gear provided with engagement toothing;
- with the connection sliding gear and the blocking sliding gear being movable in order to assume three axial positions:
- a disconnected position, in which the engagement toothing of the connection sliding gear is disconnected from the engagement toothing of the planet carrier, and the engagement toothing of the blocking sliding gear is disconnected from the engagement toothing of the output ring gear;
- a connected position, in which the engagement toothing of the connection sliding gear is connected to the engagement toothing of the planet carrier, and the engagement toothing of the blocking sliding gear is disconnected from the engagement toothing of the output ring gear;
- and
- a blocked position, in which the engagement toothing of the connection sliding gear is connected to the engagement toothing of the planet carrier, and the engagement toothing of the blocking sliding gear is connected to the engagement toothing of the output ring gear;
- and
- a spring arranged to exert a force on the connection sliding gear toward the planet carrier so as to promote, when transitioning from the disconnected position to the connected position, the engagement of the engagement toothing of the connection sliding gear in the engagement toothing of the planet carrier,
- wherein the engagement toothing of the output ring gear and the engagement toothing of the movable sliding gear extend radially.
