Title:
DIFFERENTIAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/018820
Kind Code:
A1
Abstract:
This differential device comprises: an input case that is capable of rotating around an axis, and that has an end surface oriented in the direction of the axis; a differential gear set that comprises a first side gear and a second side gear each of which is capable of rotating around the axis, a differential of the second side gear with respect to the first side gear being permitted; dog teeth that are erected, toward the end surface, on the second side gear or on an output case that supports the differential gear set; a clutch structure that is capable of meshing with the dog teeth, and that joins the output case or the second side gear to the input case upon meshing with the dog teeth; a clutch member that is capable of moving in the direction of the axis, and that includes an inner end connected to the clutch structure and an outer end exposed to the outside of the input case through the end surface; an armature that is capable of moving in the direction of the axis, that is at least partially made from a magnetic material, and that contacts the outer end; a solenoid that is supported so as to be separated from the end surface in the direction of the axis, that generates a magnetic flux in the direction of the axis to attract the armature, and that causes the clutch structure to mesh with the dog teeth with the clutch member interposed therebetween; and a spring that biases the clutch structure in a direction which causes the clutch structure to disengage from the dog teeth.
