Document Type and Number:
Japanese Patent JP6686924
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a driving force distribution device for a vehicle for suitably reducing an abnormal sound generated from a cut-off/contact device.SOLUTION: A return angle Φ around a second rotation axis C2 of a first cam member 78 when the first cam member 78 moves backward is made larger than a looseness angle Ψ up to an output shaft 62 from rear wheels 16L and 16R, so that even if a rotation speed of the output shaft 62 is reduced when a synchronizer 90 becomes nonoperation by moving the first cam member 78 backward, looseness up to the output shaft 62 from the rear wheels 16L and 16R is stopped earlier than when an outer peripheral cut-off/contact tooth 66a of a cut-off/contact sleeve 66 meshes with an inner peripheral cut-off/contact tooth 54a of a ring gear 54. Thus, a rotation speed of the output shaft 62 is recovered and in a state where difference between the rotation speed of the ring gear 54 and the rotation speed of the output shaft 62 is comparatively small, the outer peripheral cut-of/contact tooth 66a of the cut-off/contact sleeve 66 is meshed with the inner peripheral cut-off/contact tooth 54a of the ring gear 54.SELECTED DRAWING: Figure 2
