Attachment device for a tubular element, in particular for a steering column of a vehicle

The tubular part (1) passes through a middle support piece (25) which is arranged between two clamping flanges (17a, 17b). A tie rod (21) passes through the flanges (17) and bears against the external surfaces of these flanges by means of a stop (29) and a clamping device on the one hand, and a nut...

Beschreibung
Zusammenfassung:	The tubular part (1) passes through a middle support piece (25) which is arranged between two clamping flanges (17a, 17b). A tie rod (21) passes through the flanges (17) and bears against the external surfaces of these flanges by means of a stop (29) and a clamping device on the one hand, and a nut (31), on the other hand. The clamping device consists of a bistable toggle-joint system comprising two levers (40,41) located in between the stop (29) and a bearing part (34). The stop (29), the levers (40,41) and the bearing part (34) have complementary hinging surfaces which are freely engaged with each other for assembly of the clamping device. With the device according to the invention it is possible to fix a steering column which can be continuously adjusted by pivoting and/or sliding. It is also possible to absorb the torques which may be transmitted to the steering column when the anti-theft device of the vehicle is engaged. DISPOSITIVO DE FIJACION PARA UNA PIEZA TUBULAR, PARTICULARMENTE UNA COLUMNA DE DIRECCION DE VEHICULO. LA PIEZA TUBULAR (1) PASA POR EL INTERIOR DE UN SOPORTE INTERMEDIO (25) QUE SE HALLA DISPUESTO ENTRE DOS GUALDERAS DE APRIETE (17A, 17B). UN TIRANTE (21) ATRAVIESA LAS GUALDERAS (17) Y SE APOYA CONTRA LAS CARAS EXTERIORES DE LAS MISMAS POR INTERMEDIO DE UN TOPE (29) Y DE UN DISPOSITIVO DE APRIETE, POR UNA PARTE, Y DE UNA TUERCA (31) POR LA OTRA. EL DISPOSITIVO DE APRIETE ESTA CONSTITUIDO POR UN SISTEMA DE RODILLERA BIESTABLE QUE COMPORTA DOS PALANCAS (40, 41) INTERCALADAS ENTRE EL TOPE (29) Y UNA PIEZA DE APOYO (34). EL TOPE (29), LAS PALANCAS (40, 41) Y LA PIEZA DE APOYO (34) COMPORTAN SUPERFICIES DE ARTICULACION COMPLEMENTARIAS QUE SE ACOPLAN LIBREMENTE LAS UNAS CON LAS OTRAS PARA EL MONTAJE DEL DISPOSITIVO DE APRIETE. PERMITE LA FIJACION DE UNA COLUMNA DE DIRECCION REGULABLE DE MANERA CONTINUA POR OSCILACION Y/O DESLIZAMIENTO Y LA ABSORCION DE LOS PARES TRANSMITIDOS A LA COLUMNA DE DIRECCION CUANDO EL DISPOSITIVO ANTIRROBO DEL VEHICULO ES ACTIVADO.
