Claims (4)

In known ball head couplings, the holding device is designed so that the lever is held rigidly in its position of use, that is, when the coupling is closed. A U-shaped locking piece 1. Ball head coupling for trailers, with the 5 this is pivoted over the lever so that the coupling attached to the towing vehicle connecting the two legs rests on the upper half of an upwardly pointing ball head and the side of the lever. Another domed resilient locking bolt attached to this bridge, which is towed in front of this bridge, snaps into the lungshäifte a transverse holding position of the U-shaped holding bracket encompassing the spherical head in a split spherical shell, which is the pulling recess of the lever, with which it is in this Stel vehicle facing spherical shell part is locked rigidly on the lung. In order to automatically loosen this carrier attached to the coupling and to prevent its holding device from staring at it, there must only be slight play between the hanger-facing spherical shell part of the retaining bracket and the lever. It can be coupled in the direction of the trailer and in use, however, it cannot be avoided that both in the position of use by means of a lever attached to the movable spherical shell part with the movable spherical shell part, in the vehicle longitudinal direction, as well as the pivoting direction to the trailer via the lever U-shaped retaining brackets facing away from the pointing lever, even if only slightly under the action of a spring force, are deformed into one. Although such a holding device, which is formed by a spring force, can still be securely locked in place, characterized in that it would fulfill its purpose, it can in practice; that the use of the hinged spherical shell part (I b) can no longer be used, as the holding clamped lever (3) made of flexible bow is only made of flexible material with considerable effort and the lever can be pushed during the closing movement, weü the slightest thing when the clutch is closed Its opposite permissible play between the retaining bracket and the position of use can be moved and activated against the spring force caused by the flexible material during the closing pre-deformations of the retaining bracket or the lever after a short period of use, so that the parts to be moved can be latched onto one another in the latching device. rub. Such a clutch should be directed and you. 2. Ball head coupling according to claim !, there- for moving parts would have to be adapted to each other wc, characterized in that the lever (3) is on the 30. Experience shows, however, that such rep; nem the end facing away from the coupling can hardly ever be made by a raturen, so that e ■ The locking bolt (8) is penetrated, which in general requires a very high expenditure of force: a swiveling, downwardly open hand to open or close the coupling !: ken of the locking device can be locked. and click into place securely. However, the voü is omitted 3. Ball head coupling according to claim 2, there- 35 permanent locking of the holding device, then can. characterized in that the locking device is the clutch through the bumps when driving designed as a U-shaped double hook (6) and solve automatically, which is in the interest of traffic safety means a bolt on the carrier of the coupling must be avoided in unit. one in the longitudinal axis of the lever (3). In other known embodiments, the the vertical plane between their pivoting path 4 ° have been briefly described at the beginning and on the limiting stops is stored, in which the invention relates, a ball socket part is ge The locking bolt (8) of the lever (3) can be latched relative to the other and can be moved linearly towards the other is. snap-in by a spring force. The spring force ensures 4. Ball head coupling after one of the reasons that the coupling also after prolonged use speaking 1 to 3, characterized in that the 45 still closes securely. This is a disadvantage Lever (3) extends beyond the latching device so that it is a sliding guide is and runs out in a handle (9). delt by z. B. slides a pipe in another. Here, in addition to the springs, further components are required, so that the manufacturing costs 50 compared to the aforementioned clutches is not insignificant are higher. Since the clutches are subject to heavy soiling, apart from that from wear and tear, not just the risk of The invention relates to a ball head clamping of the guided parts, but in particular a coupling for trailers, in which the coupling half attached to the pulling 55 is also affected by corrosion, so that the functionality of the vehicle is impaired or even lost,
pointing ball head and on the towed vehicle The invention is based on the object of a attached other coupling half to create a spherical head spherical head coupling, which is simple and comprehensive, transversely divided spherical shell, whose spherical shell part 60, which faces the easily reliable coupling and pulling vehicle, is rigidly attached to the carrier of the coupling without difficulty and even after a long period of time, and its service life is safe to lock and to unlock again without the trailer facing spherical shell part in the event of difficulty.
Uncoupling in the direction of the trailer and movable according to the invention, this object is at a in the position of use by means of a movable ball-head coupling of the type mentioned above shell part attached, solved in the vehicle longitudinal direction 65 in that the foldable ball to Trailer pointing lever against a shell part clamped lever made of flexible elastic Spring force in a material under the action of a spring force and during the closing movement standing holding device can be locked. closed clutch on its utility laae
