초록 ▼

A telescopic coupling for use in applications such as the steering systems of heavy trucks. The coupling has modes and includes a female member, a male member, and an interposed member which are connected together in a main sliding system operable in a first operating mode in which the male and female members are axially slidable relative to one another and the coupling is rotatable substantially without circumferential play. The female member, the male member, and the interposed member are joined together in a second sliding system operable in a second operating mode in which the male and female members are axially slidable relative to one another and the coupling is rotatable with a limited amount of circumferential play. The secondary sliding system ensures the safety of the main sliding system in the event of wear of the latter by the appearance of circumferential play in the coupling.

대표청구항 ▼

An extensible coupling comprising: a female member having a hollow part, an inside wall of the female member having a non-circular cross-sectional profile; a male member having a hollow part, an external wall of the male member having a non-circular cross-sectional profile complementary to and engageable with the profile of the inside wall of the female member such that the male member is axially slidable relative to the female member without circumferential play, and an inside wall of the male member having a non-circular cross-sectional geometry; an interposed member, a first end of the interposed member having an external wall having a non-circular cross-sectional profile complementary to and engageable with the profile of the inside wall of the female member such that the interposed member is axially slidable relative to the female member without circumferential play, and a second end of the interposed member having an external wall having a non-circular cross-sectional geometry cooperable with the geometry of the inside wall of the male member such that the interposed member is axially slidable relative tot he male member with circumferential play; safety means for ensuring continuity of transmission of rotation between the female member and the male member in the event of failure of engagement between the female member and the male member, the safety means including a brake disposed between the female member and the interposed member, wherein a main sliding system is operable in a first, normal operating mode in which the male member engages the female member such that the male member and the female member slide axially relative to one another without circumferential play, the brake hindering relative axial movement between the interposed member and the female member from a position corresponding to the first operating mode of the coupling; and wherein a secondary sliding system is operable in a second, occasional operating mode in which the first end of the interposed member engages with the female member and the second end of the interposed member cooperates with the male member such that the first end of the interposed member and the female member are axially slidable relative to one another without circumferential play, and the second end of the interposed member and the male member are axially slidable relative to one another with circumferential play
