Abstract
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.
