Abstract: A coupling device for connecting a trailer to a towing vehicle is provided. The coupling comprises a drawbar with a first drawbar eye having a first inner diameter, and at least a second drawbar eye having a second inner diameter. A coupling pin of a coupling element on a towing vehicle is adapted to be stucked through one of the two drawbar eyes for coupling the drawbar to the trailer coupling element. The drawbar is adapted to be pivoted by means of a swivel-joint and to swivel in a horizontal plane about at least 180.degree., and to be secured to said coupling. Further, the trailer coupling element comprises, at its free end, two horizontal legs arranged one upon another between which the drawbar is pivoted, and at least one releasable locking pin is provided being stucked through the two legs and through one of the two drawbar eyes located between the legs for locking the drawbar at the forked drawbar (FIG. 2 ).
Abstract translation: 提供一种用于将拖车连接到牵引车辆的联接装置。 联轴器包括具有第一内径的第一牵引杆眼和具有第二内径的至少第二牵引杆眼的牵引杆。 牵引车辆上的联接元件的联接销适于通过两个牵引杆眼中的一个卡住，用于将牵引杆联接到拖车联接元件。 牵引杆适于通过旋转接头枢转并且在大约至少180°的水平面中旋转并且被固定到所述联轴器。 此外，拖车联接元件在其自由端处包括两个彼此相对布置的水平腿，牵引杆枢转在两个之间，并且提供至少一个可释放的锁定销，其通过两个腿部并通过两个牵引杆眼睛之一 位于腿之间，用于将牵引杆锁定在叉车（图2）处。

Abstract: A fifth wheel coupling for connection of a semitrailer to a tractor unit is disclosed in which a pair of symmetrical, swivel-articulated closing jaws having semicircular recesses for grasping the king pin have a split bearing comprising an outer bearing half fixed in each closing jaw and inner bearing halves rotatable with respect to the outer bearing halves. The split bearing includes a mechanism for returning each inner bearing half to a position aligned with its respective outer bearing half for uncoupling. The split bearing eliminates friction between the king pin and the closing jaws and is substantially free from wear and maintenance.
Abstract translation: 公开了一种用于将半挂车连接到牵引车单元的第五轮联轴器，其中一对具有用于抓握主销的半圆形凹槽的旋转铰接的闭合爪具有分离轴承，该分离轴承包括固定在每个闭合颚中的外轴承半部， 内轴承半部可相对于外轴承半部旋转。 分离轴承包括用于使每个内轴承半部返回到与其相应的外轴承半体对准的位置以用于解偶联的机构。 分离轴承消除了主销和闭合夹爪之间的摩擦，并且基本上没有磨损和维护。

Abstract: A fifth wheel coupling for connecting a semitrailer to a towing vehicle, which provides two swivel-articulated closing jaws with semicircular clearances for grasping a semitrailer king pin, and means for opening and closing the jaws which provide a hydraulic cylinder, a piston disposed therein with a rod having a central bore, a tappet disposed within the bore and protruding into the semicircular clearances, piston head and piston rod spaces, and a channel connecting the spaces which is closable by the tappet. Pressurization of the hydraulic cylinder opens the jaws, and contact of the semitrailer king pin against the tappet automatically closes the jaws.
Abstract translation: 用于将半挂车连接到牵引车的第五轮联接器，其提供具有半圆形间隙的两个旋转铰接的闭合爪，用于抓取半挂车主销，以及用于打开和关闭提供液压缸的钳口的装置，其中设置有活塞 具有中心孔的杆，设置在孔内并突出到半圆形间隙中的挺杆，活塞头和活塞杆空间，以及连接可被挺杆关闭的空间的通道。 液压缸的加压打开钳口，半挂车主销与挺杆的接触自动关闭夹爪。

Abstract: Disclosed is a sealing unit comprising a soft sealing ring and a thrust ring which has a greater hardness than the sealing ring. The two rings are permanently connected along a central surface of contact (b). Also disclosed is a process for producing the sealing unit comprising the steps of extruding both the sealing ring and the thrust ring, and then connecting the extruded rings along the central surface of contact.
