Definitions

• the invention relates to an adjustable damping element for a flap closing a body opening with a stop element consisting of a head and a shaft, with a pot-shaped housing, with a clamping element arranged concentrically in the housing and consisting of at least two jaws, between which there is the shaft of the stop element is located, and with a tensioning element which can be brought from a first into a second position, in the first position an axial movement of the stop element in the housing relative to the jaws is possible and in the second position the shaft is fixed in the housing is.
• the hood or trunk lid of a vehicle is supported on so-called damping elements and is braced against it without rattling. Tolerances in the manufacture of the hood or the cover on the one hand and the body forming the opening make it necessary to provide an adjustable damping element so that the height of the stop element relative to the body frame can be adapted to the particular circumstances. To make time-consuming manual adjustment to avoid len, in which the lid or the hood must be closed and opened several times to check the accuracy of the setting achieved, damping elements have already been proposed in which the setting quasi automatically when the hood or the first closing Cover takes place, so that only a fixation of the stop element in the set position is then necessary.
• the damping element accordingly consists of a stop element, which has a head and a tubular shaft, and of a housing into which the shaft of the stop element is inserted, the housing having a central tube, in the wall of which two opposite tabs are formed, which can be pressed outwards by means of a rotatable stamp, hooks arranged on the outside engaging in the inner wall of the shaft and fixing it in the housing. Since the stamp protrudes from the bottom of the housing, it is difficult to grasp, making assembly difficult.
• the driver element, the shaft and the clamping element are clamped to one another, but there is no fixation with respect to the housing, so that it cannot be ruled out that the arrangement can be loosened by vibrations occurring during driving. It is also disadvantageous that the pressure on the jaws is only exerted at the upper end, so that a frictional engagement occurs only on a narrow ring surface. A relatively large pressure must therefore be exerted on the shaft in order to generate the necessary holding force.
• the invention is therefore based on the problem of creating an adjustable damping element that is easy to assemble and ensures reliable retention of the fixed setting.
• This arrangement of the jaws means that they can rest on the shaft over their entire height, which results in a significantly better fixation with less effort.
• the jaws in the first position of the clamping element can either partially, which creates a partial form fit, which will be explained in more detail below, or completely detach from the shaft, which however presupposes that the resistance when inserting the shaft other way is effected
• the fixation in the second position is preferably improved by a positive fit, which is achieved by concentrically running grooves.
• the amplitude of the grooves simply determines the accuracy of the setting.
• the radial mobility to the outside can be limited in such a way that there is still a partial positive fit between the grooves on the jaws and on the shaft.
• the degree of toothing determines the resistance in the setting phase. This ensures that the forces with which the shaft is held between the jaws are not too small during the adjustment phase, so that it would slip too far during the adjustment process.
• the positive engagement in the second position ensures that the setting is achieved in the long term.
• the jaws are moved inwards by the clamping element via a wedge gear.
• the jaws are arranged concentrically to the shaft, the lateral surface enclosing the outside of the jaws being conical in the manner of a truncated cone towards the open side of the housing. runs, and the clamping element is provided with appropriate counter-bevels. The radial movement of the jaws takes place against the resilient action of the clamping element in the radial direction.
• the tensioning element is designed as an insert piece that can be screwed into the housing and the counter-bevels are present on lamellae which are arranged at a distance from a tubular threaded collar that carries an external thread.
• a web running around the bottom of the housing projects into this gap as a system for the lamellae of the tensioning element.
• the gap depth corresponds essentially to the height of the jaws.
• the web can also act as an inner support and guide for the threaded collar.
• the clamping element has a pin which slides in a link which is formed by a groove on the inner wall of the housing.
• the backdrop has a vertical and a circumferential section. When passing through the vertical link section, the tensioning element is brought into a position in which the clamping element is fixed in the second position. By rotating the clamping element, with the pin running through the peripheral section, it is prevented that the clamping element can come loose. The clamping element is secured in the respective positions achieved by latching in the groove.
• the clamping element is axially displaced from the first to the second position. puts. It therefore protrudes slightly above the housing in the first position. To this end, the adjustment path for the stop element must be added so that its top has a clear distance from the housing.
• the invention provides that the jaws are half cylinders, which have cutouts on both sides parallel to their direction of displacement, so that the common outer contour of the jaws is oval , and that the clamping element has two opposite, inwardly directed lugs, which lie in the cutouts in the first position so that the jaws are radially movable, and which in the second position rest on the outside of the half-cylinder and the jaws against press the shaft.
• the tensioning element In order to cause the rotation in the housing, the tensioning element is held so that it can rotate about the vertical axis of the housing in a link with a horizontal section which has a free path for a pin measured at least 90 ° in the circumferential direction.
• the pin moves in the horizontal section when the clamping element is moved from the first to the second position.
• the horizontal section should therefore have a length of 90 ° in the circumferential direction.
• the backdrop In order to be able to insert the pin into the horizontal section of the backdrop, the backdrop has a vertical vertical section which opens approximately into the middle of the horizontal section.
• the invention relates to a method for adjusting the damping element.
• this consists of first preparing the damping element for installation and screwing the tensioning element into the housing so far that a displacement of the shaft between the jaws against a frictional force is still possible.
• the damping element prepared in this way is inserted into the frame of the body opening.
• the cover is then closed, as a result of which the damping element in the housing is displaced against the set partial positive locking force.
• the clamping element is then completely screwed into the housing, the shaft being clamped between the jaws.
• the method consists in assembling the damping element in a first step, the tensioning element being inserted into the housing and oriented towards the housing such that it is in the first position in which the shaft is against a slight resistance is displaceable relative to the housing, and the stop element protrudes so far from the housing that all possible spacing dimensions are bridged that in a further step the damping element prepared in this way in the body frame, which surrounds the opening to be closed, inserted and the flap is closed, the stop element being displaced against the resistance, and in a final step the tensioning element being rotated in the horizontal section of the link, so that it assumes the second position in which the jaws fix the stop element.
• the two methods differ in that in the first case the insert piece for fixing the shaft is displaced vertically, while in the second case it is merely rotated.
• the adjustment of the stop element achieved in both cases corresponds to a support of the cover without pretensioning.
• the pretensioning is achieved in that either the head or the elevation is elastic.

• FIG. 2 shows, in the case of non-clamped jaws, these are offset radially outward so far that the grooves 16, 17 only partially engage in one another - which is to be referred to as a partial positive fit - so that the stop element comes from above exerted force this is ratcheted down.
• the clamping element 5 is arranged concentrically with the clamping element 4. It is an insert piece which can be screwed into the housing 3 and has a tubular thread collar 18 which has a thread on the outside which corresponds to a corresponding internal thread on the housing wall. At a distance from this threaded collar 18 there are four lamellae 20 arranged in a concentric circle, the inner surface of which has counter-bevels corresponding to the bevel on the jaws 14, 14 ", so that there is a large-area contact between the inside of the Slats 20 and the outside of the jaws 14, 14 "when the insert, as shown in Fig. 1, is fully screwed into the housing 3.
