MEJORAS A DISPOSITIVO DE AJUSTE DE LA POSICION ANGULAR DE UN VOLANTE SOBRE UNA COLUMNA DE DIRECCION DE AUTOMOVILES

摘要

Device for a steering wheel having a hub (2) with an axial bore (3) having a portion (4) defining a frustoconical surface adapted to cooperate with a portion (5) of the column (1) of complementary shape and first splines (6) arranged angularly in accordance with a given pitch. A screw (7) is provided for clamping the hub (2) to the column (1). The column is in the form of a tube in which is disposed an intermediate member (8) including a portion (9) defining a frustoconical surface adapted to cooperate with a portion (10) of the inner surface of the column having a complementary shape and second splines (13) adapted to cooperate with the first splines (6) forming splines of the hub (2) for preventing rotation between the hub and the intermediate member. The screw (7) clamps the hub (2) and the intermediate member (8) in such manner as to jam the column (1) between the hub and the intermediate member (8) and thus lock the steering wheel in the desired position of adjustment of the steering wheel on the column.
