A holding device hold a first member in position relative to a second member on a clamping pin. Two racks respectively one connected to the first and second members and adapted to interengage in a locked position. A return spring separates the racks in an unlocked position. An additional spring co-operates with a bracket. The racks, return spring and additional spring are mounted on the clamping pin. The additional spring bears against the bracket and operates on the mobile rack to assure complete interpenetration of the mobile rack and the fixed rack. The main application of the device is to automobile vehicle steering columns.

Steering column for a motor vehicle and comprising a body (1), a fixed portion (2) rigidly linked to the frame of the vehicle and a mobile portion (3) rigidly linked to the body (1). The column also comprises a fixed notched element (70) integral with a bracket (21) of the fixed portion (2), a mobile notched element (71) connected to the mobile portion (3), and fixing elements (51, 52, 53, 54, 55) making it possible to render integral the mobile (3) and fixed (2) portions in a locked position in which the notches (80, 90) of the two notched elements (70, 71) cooperate by shape mating. An elastic device (72) is provided between the fixed (70) and mobile (71) notched elements, causing the elements (70, 71) to be moved apart from each other, when the fixing elements (51, 52, 53, 54, 55) are inactivated and thus allowing to unlock the link between the fixed (2) and mobile (3) portions.
摘要:
A steering column including an upper body, two connection flanges for connecting the upper body to a support element, and a tightening and blocking device the upper body in position on an internal tube, where the tightening and blocking device includes a clamp screw extending through the flanges, a set of cams comprising a fixed cam and a movable cam mounted such that it can move freely in translation along the clamp screw and arranged so that it can bear on one of the flanges, a rack capable of cooperating with a notched arrangement provided on the other flange, and a resilient means arranged between the movable cam and the rack in order to exert a return force on the rack in the direction of the notched flange.

According to the disclosure, the steering column comprises a steering shaft rotatingly mounted in a tube-body provided on a side mount of a fixed bearing assembly via a lateral mechanism. The column can be adjusted in height and/or depth by an axis clamping system with a clamping rod (interacting with the lateral mechanism. The lateral mechanism comprises a bearing member provided between the side mount and a side member of the tube-body. A cross-section arranged between the bearing member and the side member enables counter-rotation. The lateral mechanism includes a system for adjusting the sliding clearance on the clamping rod using a bearing member and an adjustable clamping head.
摘要:
Device for coupling an inner shaft and an outer shaft which slide along their common axis with balls positioned between the two shafts. The balls rest directly in axial grooves of the outer shaft and on two rails positioned in axial grooves of the inner shaft. The two rails pivot about the balls, by pressing against flanks of mating curved profile of the axial groove, and are held in place by an elastic element which presses against the bottom of the axial groove.

摘要:
The column comprises a column body (1) mounted on the frame via brackets (5, 6) comprising openings (15, 16) for the passage of fixing elements (12) to the frame, and capsules (10, 11) enclosing the brackets and retained by the fixing elements (12). The openings comprise guiding surfaces (21) disposed two by two on both sides of a vertical plane (31) containing the axis (32) of the column. In the event of an impact occurring, the brackets integral with the column body (1) move with respect to the capsules fixed to the frame, the guiding surfaces (21) sliding into the capsules (10, 11). These movements absorb a portion of the energy due to the impact and the surfaces ensure the axial guiding of the column. The capsules are made of plastics and a metallic insert is inserted between the fixing elements and the capsules. The column is particularly useful for motor vehicles provided with an inflatable safety air bag should an impact occur.

A device for adjusting a steering column includes a body and a cap assembled by a pivot and a connection element enabling the displacement of the body with respect to the cap under the action of a motor-reduction unit mounted on the body. The device is characterized in that the connection element includes at least one arm of which a first end is attached to the cap and a second end is connected to a threaded rod with vertical displacement cooperating in rotation with the drive shaft of a motor-reduction unit so that the arm forms a hinge enabling the reversible angular displacement of the body with respect to the cap.
摘要:
A homokinetic joint for linking a driving shaft and a driven shaft of an automotive steering column for transmission of rotation between the driving shaft and the driven shaft. The joint has two opposite end yokes with a coupling yoke intermediate the two end yokes. The end yokes each have an end hub for linking a respective one of the shafts thereto and branched arms defining a yoke or fork opposite the hub for linking the end yoke to the coupling yoke. Two pivotable cross-pieces link the two end yokes respectively to the coupling yoke for positioning the axes of the shafts for homokinetic transmission of torque. A center ball joint unit has a ball stud and spherical ball fixed on one of the end yokes and a guide carried by the other of the end yokes. A sleeve is disposed in the guide and the ball is disposed in the sleeve. The spherical ball is angularly movable in the sleeve for angular offset variation between the shafts during transmission of torque.
