Definitions
- the invention relates to a tilt pin mechanism for the clamping device of a positionable automotive steering column with the features mentioned in the preamble of claim 1.
- Such a tilt pin mechanism is available, for example, to build up the clamping forces in a clamping device according to DE 44 00306 AI.
- a clamping device is disclosed, by means of which a housing accommodating the steering column with a holder fixed to the body in the clamped state with corresponding friction surfaces lie against one another.
- the clamping forces are built up by means of a plurality of tilting pins which are supported at one end in an abutment on the housing and at the other end in an abutment on a pin collar.
- the rotation of the bolt in one direction means that the tilting pins can be brought into an arresting stop position via an axial extended position parallel to the bolt axis, in which the necessary contact forces for the friction surfaces arranged between the body-fixed holder and the housing are applied.
- the tilt pins come into a release position that removes the clamp connection, in which the tilt pins are inclined at a slight angle to the longitudinal axis of the bolt.
- the clamping device described in the above-mentioned document using a tilting pin mechanism has proven itself in principle and has however, certain disadvantages, in particular with regard to increased requirements for the clamping action. These consist, in particular, in that the clamping path, ie the stroke which the tilting pins carry out from their release position into the locking position, is relatively small. In addition, from the already small clamping path by passing through the tipping pin position beyond the axial extended position into a locking position, the theoretically existing clamping path is somewhat lost again in that the tilting pins are held in the stable locking position.
- a counter bearing for example in the form of an axial needle bearing, is required for the tilting pin mechanisms mentioned, which permits the rotary movement of the actuating element to tilt the tilting pins under force.
- the object of the present invention is therefore to develop a tilt pin mechanism of the generic type described at the outset in such a way that larger clamping paths can be realized.
- the mechanism according to the invention should have compact dimensions and be simple and inexpensive in its construction.
- the actuating ring which causes the tilting pins fitted between the actuating ring and a bolt collar to tilt, has at least one recess for a further tilting pin on the second end face facing away from these tilting pins, the other end of this tilting pin being in one direction axially displaceable thrust washer supports the central axis of the actuating ring.
- Another advantageous embodiment of the subject matter of the invention also provides that only two of the existing tilting pins in the lockable stop position of the actuating ring are in the "over-dead center position", ie. that is, in which the axial extension is parallel to the central longitudinal axis of the bolt, while the other two tilting pins are arranged exactly in the axial extension. Due to the different arrangement of the tilting pins in the locking position, the clamping path can also be increased, and thus the clamping effect of the entire mechanism can be further increased.
- the actuation ring can be rotated by coupling it with a hand lever.
- FIG. 1 shows a side view of the tilt pin mechanism according to the invention
- FIG. 2 shows a sectional view through the mechanism according to the invention along the section line A-A from FIG. 1,
- FIG 3 is a sectional view through the tilt pin mechanism according to section line B-B of Figure 1 and
- FIG. 4 shows a sectional view along the section line C-C from FIG. 2.
- FIG. 1 the tilting pin mechanism designated in its entirety with 1 is shown together with a hand lever 2 coupled to the tilting pin mechanism 1.
- the hand lever 2 serves to actuate the tilt pin mechanism, the detailed structure of which is illustrated with reference to FIGS. 2 to 4.
- the entire mechanism essentially consists of a centrally arranged pin 3 with an end collar 4, an actuating ring 5 to which the hand lever 2 is attached, a total of four tilt pins 6 and two pressure disks 7 and 8 arranged laterally of the actuation ring 5.
- the pressure disk 8 lies with its outside facing away from the tilting pins on the pin collar 4.
- the thrust washer 8 there are spherically shaped recesses 9, the contour of which is adapted to the ends of the tilting pins 6.
- the tilting pins 6 With its end facing away from the thrust washer 8, the tilting pins 6 are arranged in corresponding recesses 10 of the actuating ring 5 which are designed as ball sockets.
- the thrust washer 8 serves as a contact surface for two tilt pins, the tilt pins being offset by 180 degrees on a common radius.
- the actuating ring 5 also has two on the end face that faces away from the pressure disk 8 Has recesses 11, in turn, the tilt pins 6 are received. These tilting pins are supported on the one hand on the bottom of the recess 11, which are formed analogously to the recesses 10 as ball sockets. The other end of the tilt pins 6 is supported on the thrust washer 7, which, like the thrust washer 8, also has recesses 12 which are hemispherical in shape and correspond to the end of the tilt pins 6.
- the diameter dimensions of the recesses 10 and 11 are chosen such that the tilting pins are arranged in the bores with a slight angular offset, but essentially parallel to the central longitudinal axis 13 of the bolt 3.
- a rotation of the actuating ring 5 by means of the hand lever 2 has the effect that the slightly inclined bolts 3 are first brought into a position in which their longitudinal axis 14 are aligned parallel to the central longitudinal axis 13 of the bolt 3.
- a further rotation of the actuating ring 5 then causes the tilting pins to be brought into a correspondingly stable stop position beyond the parallel orientation mentioned.
- the lifting movement of the tilting pins 6 brings about an axial displacement of the pressure disks 7 and 8, as a result of which, in a manner not shown here, within of the clamping mechanism for a vehicle longitudinal column, holding forces can be built up within the friction pairings there.
- a special embodiment of the subject matter of the invention provides that only two of the existing four tilting pins 6 are used for locking the tilting pins in the clamping position. This means that in the locked position of the tilt pin mechanism there are two tilt pins 6 in the dead center position, whereas the two other tilt pins are aligned with their longitudinal axis 14 parallel to the central longitudinal axis 13 of the bolt 3. In this way, the stroke of these tilt pins 6 is not reduced again due to the over-dead center position as a result of the locking, so that a, albeit slight,
