A differential device (1) for a self-propelled wheeled vehicle, includes an input ring gear (2), two shafts separate from each other, two clutch mechanisms each including a first clutch member (3) mounted integral in rotation to one of the shafts, and a second clutch member (4) mounted freely rotatable relative to the shaft and capable of being rotated by the ring gear (2), the second clutch member being capable of being moved axially. Each second clutch member is provided with elements (44) for bearing contact with the other second clutch member, the elements for bearing contact being capable, in a first given angular configuration of the second clutch members relative to each other, of keeping the second clutch members in the engaged position, and the elements for bearing contact also being capable, in a second given angular configuration, of allowing the second clutch members to shift to the disengaged position. |

1. A differential device for an automotive wheeled vehicle (10), said device (1) comprising:
an input ring gear (2) capable of being rotated by the motor of said vehicle, two wheel (8) shafts (7) separate from one another and allocated to either side of the ring gear (2) coaxially to said ring gear (2), two clutch mechanisms each comprising a first clutch element (3) mounted in a rotationally fixed manner with one of said wheel (8) shafts (7) and a second clutch element (4) mounted in a freely rotatable manner relative to said shaft (7) and capable of being rotated by the ring gear (2), said second clutch elements (4) being positioned between said first clutch elements (3), for each clutch mechanism, said second clutch element (4) being capable of being displaced axially between a close position of said first clutch element (3) in which it is engaged with the first clutch element (3) and a spaced apart position of said first clutch element (3) in which it is disengaged from the first clutch element (3), said ring gear (2) and the second clutch elements (4) being provided with co-rotational coupling means (24, 42),wherein every second clutch element (4) is also provided with supporting contact means (44) with the other second clutch element (4), said supporting contact means (44) being capable, in a first given angular configuration of the second clutch elements (4) relative to one another, of keeping the second clutch elements (4) in the engaged position with the first corresponding clutch elements (3),and said supporting contact means (44) also being capable, in a second given angular configuration of the second clutch elements (4) relative to one another, unlike in the first configuration, of allowing the second clutch elements (4) to shift into the disengaged position in relation to the first clutch elements (3). |
