    专利说明:

    The invention relates to a hold-down according to the preamble of claim 1.
    A hold-down is a part of a vehicle clutch, wherein the hold-down holds down the coupling socket of a vehicle clutch on a coupling ball of the vehicle clutch. In this case, the holding-down device is locked in a hold-down position, in which the holding-down device contacts the side of the coupling socket facing away from the coupling ball. For a reliable and low-wear operation of the trained as a ball clutch vehicle coupling, it is necessary that the coupling socket rests with a certain play on the coupling ball. The hold-down has for this purpose an adjusting screw with a contact surface, through which the distance between the coupling ball and the contact surface can be adjusted continuously in a predeterminable range. In order to fix the setting of the adjusting screw for the operation, it is known to clamp a protruding part of the adjusting screw with a lock nut.
    By this construction, there is an increased space requirement, since it is necessary for the fixation with the lock nut, that the adjusting screw protrudes clearly from the rest of the hold-down.
    The disadvantage of this is that in the rear of a towing vehicle, the space is usually very limited, as often many different coupling options and connections are to be accommodated, and the internals in the rear should therefore be designed to save space. By the locknut, the height of the holddown is significantly increased. Furthermore, there is the problem with the lock nut that their fixing a high power requirement is necessary, and that in a careless tightening the lock nut, the adjustment of the adjusting screw can be adjusted.
    The object of the invention is therefore to provide a hold-down of the type mentioned, with which the mentioned disadvantages can be avoided, which is formed platzersparrend but still can be easily and reliably adjusted.
    This is achieved by the features of claim 1 according to the invention.
    This results in the advantage that the hold-down can be built much lower, as a projection of the adjusting screw from the hold-down body is no longer necessary. By the side of the threaded bore arranged clamping device, the required size of the blank holder can be reduced. Due to this lower height of the space consumed by internals can be reduced in the rear of a towing vehicle, creating more installations are possible, or work in the rear area are simplified. The missing locknut also reduces the likelihood that a cable will tangle to the hold-down during operation. Furthermore, the clamping device makes it possible to fix the adjusting screw, without the risk that the adjusting screw is thereby adjusted. Furthermore, no contact surface for the lock nut around the threaded hole must be taken into account in the shape of Niederhaltergrundkörpers more, whereby the hold-down basic body can be made more compact.
    The subclaims relate to further advantageous embodiments of the invention.
    It is hereby expressly referred to the wording of the claims, whereby the claims at this point are incorporated by reference into the description and are considered to be reproduced verbatim.
    The invention will be described in more detail with reference to the accompanying drawings, in which only a preferred embodiment is shown by way of example. Showing:
    Fig. 1 shows a preferred embodiment of the blank holder as an axonometric representation;
    Fig. 2 shows the preferred embodiment of the hold-down in front view;
    Fig. 3 shows the preferred embodiment of the hold-down in plan view; and FIG. 4 shows the preferred embodiment of the hold-down in side view.
    1 to 4 show a preferred embodiment hold-down device 1 for holding down a coupling socket of a vehicle clutch on a coupling ball of the vehicle clutch, wherein the hold-down 1 has a hold-down main body 2 with a threaded bore 3, wherein in the threaded bore 3, an adjusting screw 4 is arranged, wherein the Adjusting screw 4 has a contact surface 5 for contacting the coupling socket. A hold-down device 1 holds at one, designed as a ball coupling vehicle coupling the coupling socket on the coupling ball. The hold-down device 1 can for this purpose with a hold-down bracket 9 of the coupling part pivotally or releasably connected, wherein the hold-1 is locked for operation in a hold-down position.
    The vehicle clutch may in this case be, in particular, a vehicle clutch for the agricultural sector, that is to say for a tractor and an agricultural trailer.
    The hold-down device 1 has a hold-down basic body 2 with a threaded bore 3. The hold-down basic body 2 is in this case that basic body which makes up the major part of the hold-down 1. The hold-down basic body 2 may in particular be in one piece. Furthermore, the hold-down base body 2 may particularly preferably be a cast part, in particular made of cast iron or steel. The threaded hole 3 is a hole in the hold-down body 2, which is provided with an internal thread. The threaded hole 3 can be produced in particular by drilling. But there are also other manufacturing methods for producing threaded hole 3 conceivable as punching, forming or molding.
    In the threaded hole 3, the adjusting screw 4 is arranged, which is provided as the only part of the blank holder 1 to contact the coupling socket. The adjusting screw 4 may be formed in particular as a worm screw. By turning the adjusting screw 4, the distance between the contact surface 5 and the coupling ball in the hold-down position can be adjusted continuously. This is necessary to adjust the hold-down 1 to the thickness of a coupling socket or to compensate for the wear on the contact surface 5.
    It is provided that the hold-down device 1 has a clamping device 6 for clamping the adjusting screw 4 in the threaded bore 3, and that the clamping device 6 is arranged laterally of the threaded bore 3. The fixation of the adjusting screw 4 is therefore carried not by a lock nut directly on the adjusting screw 4, but by a lateral clamping of the adjusting screw 4 in the threaded hole 3. This pinching can be done for example by compressing the internal thread of the threaded hole 3 and / or by a direct lateral Applying the clamping force on the adjusting screw 4. The lateral arrangement of the clamping device 6 refers to the fact that the clamping device 6 is not arranged like a lock nut in an extended longitudinal axis of the threaded hole 3, but laterally of the threaded hole 3, or the longitudinal axis of the threaded hole 3. In particular the clamping device 6 may be formed to exert a laterally acting, in particular substantially perpendicular to the longitudinal axis of the threaded bore 3 acting, clamping force on the adjusting screw 4 in the threaded hole 3.
    This results in the advantage that the hold-down device 1 can be built much lower, since a projection of the adjusting screw 4 from the hold-down base body 2 is no longer necessary. By the side of the threaded bore 3 arranged clamping device 6, the required size of the blank holder 1 can be reduced. Due to this lower height of the space consumed by internals can be reduced in the rear of a towing vehicle, creating more installations are possible, or work in the rear area are simplified. The lack of lock nut also reduces the likelihood that a cable tangles to the hold-down 1 during operation. Furthermore, the clamping device 6 makes it possible to fix the adjusting screw 4 without the risk that the adjusting screw 4 will be displaced. Furthermore, in the shape of the hold-down base body 2, no contact surface for the lock nut around the threaded hole 3 must be taken into account, whereby the hold-down base body 2 can be made more compact.
    Furthermore, a coupling part of a vehicle clutch comprising a holding-down device, a coupling ball and a hold-down holder 9 is provided. The center of the coupling ball can in particular substantially in one
    Extension of the longitudinal axis of the threaded hole 3 are arranged. The hold-down 1 cooperates with the coupling ball to hold the coupling socket on the coupling ball. For this purpose, the hold-down device 1 can be connected in a fixed position with at least one bolt 10 with the hold-down holder 9 in the hold-down position. In FIGS. 1 to 4, the hold-down device 1 with the hold-down holder 9 is shown in the hold-down position. The hold-down bracket 9 can be attached to the remaining coupling part.
    The hold-down device 1 and the hold-down holder 9 may in particular have bolt passage openings 11 for receiving the at least one bolt 10. The bolts 10 can in particular by means of a splint 12, preferably a Klappsplints, are fixed in the bolt passage openings 11. In Fig. 3, the upper pin 10 is not shown.
    The hold-down basic body 2 may, in particular, have a substantially planar cover surface 13, wherein preferably the longitudinal axis of the threaded bore 3 is inclined to a normal vector of the cover surface 13.
    Furthermore, it can be provided that the hold-down basic body 2 has two substantially parallel and planar side surfaces 14.
    This much more compact design can be achieved in that no contact surface is necessary for a lock nut.
    Furthermore, it can be provided that the hold-down basic body 2 has a first part 15, which is arranged in the hold-down position in the hold-down holder 9, and a, formed on the first part 15 and substantially wedge-shaped second part 15, wherein in the second part 15 the Threaded hole 3 is arranged. Furthermore, it can be provided that the clamping device 6 is formed in the second part 15 of the hold-down base body 2.
    The coupling part may in particular be attached to a towing vehicle.
    Furthermore, a vehicle clutch comprising the coupling part and a coupling socket is provided. The coupling socket has a receiving socket with a part-spherical inner surface. The coupling socket is placed in a coupled state of the vehicle clutch on the coupling ball of the coupling part, whereby a pivotable about three axes connection between the coupling part and the coupling socket is formed.

    The vehicle combination comprises in particular a towing vehicle with the coupling part, and a trailer with the coupling socket.
    Particularly preferably, it can be provided that the threaded bore 3 has at least one lateral slot 7, wherein the slot 7 separates two areas of the holddown base body 2, and that the clamping device 6 is formed, the two separated by the slot 7 areas of Niederhaltergrundkörpers 2 predeterminable together to press. Through the slot 7, a cross section of the threaded hole 3 is easier to deform, so that by squeezing the two separated by the slot 7 areas the adjusting screw 4 is clamped in the threaded hole 3, and thereby fixed.
    According to an embodiment, not shown, the slot 7 may extend only partially from the threaded hole 3 in the hold-down base body 2, so that the threaded hole 3 is completely enclosed with the slot 7 of the hold-down base body 2.
    Particularly preferably, it can be provided that the at least one slot 7 is open-edged, and extends from the threaded hole 3 to a free end 8 of the hold-down base body 2. The free end 8 of the hold-down basic body 2 can in particular be an end of the hold-down basic body 2 facing away from the hold-down holder 9. The free end 8 is in particular a, the first part 15 of the hold-down base 2 opposite end of the second part 16 of the hold-down body 2. As a result, the slot 7 and the threaded hole 3 with little force compressible, whereby the clamping device 6 may be formed and easy to operate is.
    Furthermore, it can be provided that the clamping device 6 has a clamping element for generating a clamping force.

In the passage opening 18, a recess may be provided for the screw head, so that the screw head does not protrude beyond the side surface 14.
    As an alternative to the screw can be provided that the clamping element is an eccentric. Although the eccentric requires more space than a screw, it can also be operated without tools, in contrast to the screw.
    According to a preferred embodiment, not shown, it can be provided that the second threaded bore 17 is normal or oblique to the threaded bore 3, and opens into the threaded hole 3. The clamping action of the clamping device 6 does not arise in this case by the deformation of the threaded hole 3, but by a screw presses directly on the adjusting screw 4.
    It can be provided that the clamping device 6 has a plurality of clamping elements, which act in particular redundant to each other.
