(54) СЕДЕЛЬНО-СЦЕПНОЕ УСТРОЙСТВО(54) SEPARATE-COUPLING DEVICE

Изобретение относитс к седель;НО-сцепным устройствам с упругими шарнирами, которые устанавливаютс на транспортных машинах, преимущественно на автомобильных т гачах.The invention relates to saddles; BUT coupling devices with elastic hinges, which are mounted on transport vehicles, mainly on automobile tonnage.

Известно седельно-сцепное устройство , содержащее седельную плиту и энергопоглощающие элементы, выполненные в виде резиновых шарниров 1Known saddle-coupling device containing a saddle plate and energy absorbing elements made in the form of rubber hinges 1

Недостат сом его вл етс то, что дл обеспечени продольного качани полуприцепа относительно т гача необходимо иметь шарниры большого диаметра , что усложн ет конструкцию устройства , а отсутствие ограничителей деформации шарниров снижает их надежность .The disadvantage of it is that in order to provide longitudinal swing of the semi-trailer relative to the load, it is necessary to have large diameter hinges, which complicates the design of the device, and the absence of limiters of the deformation of the hinges reduces their reliability.

Известно и другое седельно-сцепное устройство, содержащее седельную плиту с гнездами под опорные кронштейны, в которых размещены упругие шарниры с наружными разрезными втулками 2.It is also known that there is another fifth wheel hitch device, which contains a saddle plate with sockets for support brackets, in which elastic hinges with outer split sleeves 2 are placed.

Недостатком его вл етс то, что упругие шарниры, соедин ющие опорный кронштейн с седельной плитой , воспринимают противоположно направленные силы, что вызывает поГвьлшение напр жени в элементах шарниров , снижает их надежность и приводит к усложнению конструкции.The disadvantage of it is that the elastic hinges connecting the support bracket to the saddle plate perceive oppositely directed forces, which causes tension in the hinge elements, reduces their reliability and leads to a complication of the structure.

Цель изобретени - повышение надежности устройства путем исключени осевого перемещени седельной плиты и упрощение конструкции.The purpose of the invention is to increase the reliability of the device by eliminating the axial movement of the saddle plate and simplifying the design.

Дл этого на наружных разрезных For this on the outer cutting

o втулках выполнены эксцентричные выступы, а в отверсти х опорных кронштейнов - кольцевые выточки дл захода указанных выступов; радиус каждого эксцентричного выступа равен с радиусу наружной разрезной втулки; кроме того, в гнездах седельной плиты могут быть размещены ограничители деформации упом нутых упругих шарниров дл взаимодействи с опорными кронштейнами.o eccentric protrusions are made in the sleeves, and annular undercuts are provided in the holes of the support brackets for approaching said protrusions; the radius of each eccentric protrusion is equal to the radius of the outer split sleeve; in addition, strain reliefs of the aforementioned elastic hinges may be placed in the seats of the saddle plate for engagement with the support brackets.

Claims

The fifth wheel coupling consists of a saddle plate 1 with slots 2 and 3, which is connected with supports b and 7, axes 4 and 5 with Ka and kda. The support consists of a bracket 8 and two hinges 9 / The bracket O has two annular recesses 10 and 1.1. The hinge 9 consists of an internal sleeve 12 and an external split ki, consisting of two parts 13 and 14. The space between the sleeves is filled 15, Part 13 i-; 14 of the outer sleeve and the eccentric protrusions 16 and 17, which fit into the annular recesses 10 and 11 of the bracket 8, I will fix the hinge from axial movement due to the elasticity of the rubber 15. into the slots 2 and 3 of the saddle plate 1 by inserting the ply oi heat sinks 18.- and 19, which are arranged in such a way that BO BO; ;; transversely swing to a limit of ± 3 and prevent the hinges from collapsing with significant overload. A locking mechanism consisting of clamps 20 and 21 is attached to the saddle plate 1; arm 22 with spring 23, latch 24 with spring 25, handles 26 and fuse 2. Claim 1. The fifth wheel hitch, containing a saddle plate with gnez .1J - T-t dami under the support brackets in which elastic hinges are placed with outer split sleeves, in order to improve the reliability of the device by eliminating the axial movement of the saddle plate and simplifying the design, eccentric protrusions are made on the outer split sleeves, and in the holes of the support brackets Glasses for said call, projections. 2. A device according to claim 1, characterized in that the radius of each eccentric protrusion is equal to the radius of the outer split sleeve. 3. The device according to claim 1, of which is h, in that the deformation stoppers of said elastic hinges are placed in the seats of the saddle plate for interacting with the support brackets.
