Abstract: front page image
(EN)A steering column assembly comprises a steering column shroud comprising an inner and an outer tubular member (10, 20), a support bracket (100) which is fixed to part of the vehicle, and a clamp assembly which includes a cam mechanism having a fixed portion (220) and a moving portion (230) and a clamp pin (150) which passes through arms (130, 140) of the support bracket, the clamp pin being provided with a first reaction member (200) located towards one end of the pin outside of one arm (140) of the support bracket and a second reaction member (210) located towards the other end of the clamp pin outside of the other arm (140) of the support bracket such that the arms of the bracket are located on the clamp pin between the reaction members (200, 210) and with the cam assembly located between the outside of one arm (130) and one of the reaction (210) members. The fixed cam portion (220) is mechanically connected to the support bracket such that at least during an initial release phase of the clamp assembly the force required to produce a rotational movement of the fixed cam portion relative to the support bracket exceeds any rotational force exerted on the fixed part due to strain energy stored in the assembly.
(FR)L'invention porte sur un ensemble colonne de direction qui comprend une gaine de colonne de direction comprenant des éléments tubulaires intérieur et extérieur (10, 20), une console de support (100) qui est fixée à une partie du véhicule, et un ensemble de serrage qui comprend un mécanisme à came ayant une partie fixe (220) et une partie mobile (230) et une broche de serrage (150) qui passe à travers des bras (130, 140) de la console de support, la broche de serrage présentant un premier élément de réaction (200) placé en direction d'une extrémité de la broche à l'extérieur d'un bras (140) de la console de support et un second élément de réaction (210) placé en direction de l'autre extrémité de la broche de serrage à l'extérieur de l'autre bras (140) de la console de support de sorte que les bras de la console soient placés sur la broche de serrage entre les éléments de réaction (200, 210) et l'ensemble came étant placé entre le côté extérieur d'un bras (130) et l'un des éléments de réaction (210). La partie fixe (220) de la came est reliée mécaniquement à la console de support de sorte qu'au moins pendant une phase de desserrage initiale de l'ensemble de serrage, la force nécessaire pour produire un mouvement de rotation de la partie fixe de la came par rapport à la console de support soit supérieure à une force de rotation exercée sur la partie fixe qui est due à l'énergie de contrainte accumulée dans l'ensemble.
