Title:
DIFFERENTIAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/029081
Kind Code:
A1
Abstract:
A differential device for outputting torque around an axis is provided, comprising: a casing comprising a first wall extending in a radial direction at a first end with respect to the axis, a second wall extending in the radial direction at a second end with respect to the axis, and a peripheral wall communicating the first wall and the second wall, the first wall, the second wall, and the peripheral wall defining a chamber; a differential gear set that comprises a first side gear housed in the chamber and facing the first wall, a second side gear facing the second wall, a plurality of pinion shafts extending in the radial direction, and a plurality of pinion gears that are rotatably supported by the pinion shafts, respectively, and are meshed with the first side gear and the second side gear, the differential gear set differentially distributing the torque received by the pinion shafts to the first side gear and the second side gear; a friction clutch that is disposed between the first side gear and the first wall, and brakes the first side gear with respect to the first wall; a cam mechanism that is disposed outside the casing adjacent to the second wall and coaxially with the axis, and that converts a rotating force around the axis into a thrust force in the direction of the axis; and a transmission member that includes a plurality of plungers each extending between the plurality of pinion gears or the plurality of pinion shafts in parallel to the axis, and being capable of transmitting the thrust force, the transmission member contacting the friction clutch to apply the thrust force thereto.
