Description

  • The present invention relates to a hinge assembly for articulating a pull rod to a car body, the hinge assembly comprising a pull / push means disposed on the carriage box end of the pull rod for transmitting tensile and impact forces acting on the pull rod to a base plate connected to the body wherein the pulling / pushing means comprises a connected to the carriage box end of the tie rod, the tie rod in the longitudinal direction extending centerpiece which extends through a provided in the base plate passage opening and has a zugstangenseitigen front spring plate and a carriage box side rear spring plate, and wherein the Zug- / shock device for damping the tensile and impact forces to be transmitted further at least one arranged between the front spring plate and the base plate in Zugstangenlängsrichtung front spring element made of elastic material and the Indirectly arranged between the base plate and the rear spring plate in Zugstangenlängsrichtung rear spring element made of elastic material.
  • Such a joint arrangement is known for example from rail vehicle technology and is usually used in clutches and joints for the connection of car bodies or complete trains with each other by means of automatic couplings or short couplings for use.
  • To explain the basic structure of such a joint arrangement, reference is made to FIG. 1a, in which a known from the prior art joint assembly of the type mentioned is shown. Fig. 1b shows the hinge assembly of Fig. 1a in a pressurized condition, i. in a condition when compressive forces act on the drawbar and are damped by means of the draw / push device integrated in the articulated assembly and subsequently transferred to the associated body of the vehicle.
  • The integrated in the illustrated in Fig. 1a hinge assembly 100 has a total of three rubber springs as spring elements 116, 117, wherein two of the three spring elements 116 between a zugstangenseitigen front spring plate 114 and connected to the (not explicitly shown) car body Base plate 111 are arranged. Another elastomeric spring element 117 is disposed between the base plate 111 and a carriage side rear spring plate 115. In the unloaded state of the joint arrangement shown in Fig. 1a, the two front spring elements 116 between the front spring plate 114 and the base plate 111 and the rear spring element 117 between the base plate 111 and the rear spring plate 115 are biased. In detail, the in the in Fig. 1a illustrated and known from the prior art joint assembly integrated pull / push device 100 connected to the carriage body end of the tie rod 2 and the tie rod 2 extending in its longitudinal direction center piece 112, which extends through a provided in the base plate 111 passage opening extends, wherein the individual spring elements 116, 117 pushed onto the center piece 112 and with the aid of the front and rear spring plate 114, 115 are clamped with a lock nut 118.
  • Fig. 1b shows the known from the prior art joint arrangement of FIG. 1a in a pressurized state, in which compressive forces on the tie rod 2 and thus on the connected to the carriage body end of the tie rod 2 and the tie rod 2 in its longitudinal direction extending center piece 112th the pull / push device 100 act. This pressurization causes the tie rod 2 and the center piece 112 of the pull / push device 100 is moved with the zugstangenseitigen front spring plate 114 toward the car body, so that the distance between the front spring plate 114 and connected to the car body base plate 111 in comparison is reduced to the unloaded state shown in Fig. 1a. The two between the front spring plate 114 and the base plate 111 arranged elastomeric spring elements 116 are - compressed due to the action of the compressive forces, the compressive forces are conducted in a damped manner via the compressed spring elements 116 on the base plate 111 of the car body. It can be clearly seen from FIG. 1b that, in the pressurized state, the distance between the carriage-box-side end face of the base plate 111 and the rear spring plate 115 firmly screwed to the center piece 112 of the pull / push device 100 is less than that shown in FIG. 1a Condition increases, wherein the arranged between the base plate 111 and the rear spring plate 115 rear spring element 117 is set in a relaxed state.
  • As spring elements in the pull / push device 100 of the known from the prior art and exemplified in Figures 1a and 1b hinge assembly generally hollow springs made of an elastomeric material used, the cross-sectional shapes of these hollow springs usually have a circular design due to design. The spring elements 116, 117 take over the function of dampening the tensile and impact forces occurring in a power transmission from the drawbar 2 to the car body in the pull / push device 100. Another function is that in the spring elements 116, 117, a part of the energy generated during power transmission is dissipated.
  • In the conventional solution, as shown in Figures 1a and 1b, the center piece 112 of the pull / push device 100 is guided by means of a ball bush arrangement 119 through the opening provided in the carriage body connected to the base plate 111 through opening. The center piece 112 of the pull / push device 100 and thus also the pull rod 2 connected to the center piece 112 are at least partially supported by the ball bushing arrangement 119 in the passage opening of the base plate 111.
  • In the joint arrangement known from the prior art shown in FIGS. 1 a and 1 b, the drawbar 2 or the center piece 112 connected to the pull rod 2 of the pull / push device 100 is correspondingly provided by means of a drawbar support device 120 provided for this purpose supported. This drawbar support device 120 may further assume the function of the center reset of the pull rod 2 and thus of the center piece 112 of the pull / push device 100 connected to the pull rod 2.
  • In this generic joint arrangement, a solution is already provided with the ball bushing arrangement 119 in order to minimize the wear occurring during operation of the spring elements 116, 117 provided in the joint arrangement. However, such a ball bushing arrangement 119 due to the forces acting on the joint assembly and sometimes extreme forces in terms of their structure, since they must be designed according to the expected requirements. In particular, the deflection angle of the pull rod achievable with the conventional hinge assembly is limited to a relatively small range due to the manner of guiding the center piece 112 by the feedthrough opening provided in the base plate 111.
  • The invention is therefore based on the object to further develop a hinge assembly of the type mentioned in that on the one hand, the hinge assembly is simpler in its entirety, at the same time early wear of the joint assembly provided in the spring elements can be optimally prevented, and on the other hand, the transfer of tensile and compressive forces of the pull rod on the car body is made possible even at high deflection angles.
  • This object is achieved with a hinge assembly of the type mentioned in the present invention that the at least one front spring element and the at least one rear spring element form-fitting surround the center piece of the pull / push device and are designed such that they are each in the vertical and horizontal directions support the base plate, and in particular on the opening provided in the base plate.
  • The solution according to the invention has a number of significant advantages over the known from the prior art and explained above hinge assemblies. In particular, the fact that the front and rear spring element form-fitting surround the tie rod and then supported on the base plate in the vertical and horizontal directions, these spring elements not only serve to dampen the tensile and impact forces that are transmitted from the joint assembly, but also take over also the function of supporting the coupling rod within the provided in the base plate passage opening. Furthermore, the spring elements take over the task of guiding the coupling rod in the passage opening. In contrast to the solutions known from the prior art, a complex ball bushing arrangement or other solutions is thus eliminated in the case of the joint arrangement according to the invention. which guide and support the coupling rod inside the plate. Thus, the complexity of the structure of the hinge assembly can be reduced. In particular, with the solution according to the invention optionally also be dispensed with a separately executed drawbar support.
  • The spring joint according to the invention thus represents a simple variant of the articulation and support, wherein the basic structure of the spring joint similar to the existing and initially described hinge assemblies in which elastomeric spring elements are used in the form of hollow rubber springs, which basically have in the center piece and the hollow springs circular cross-sections and primarily assume the function of damping the tensile and impact forces transmitted by the joint assembly. Specifically, the basic structure of the spring joint is composed of a bolted tie rod with spring plates, a front and rear rubber element and a base plate against which the spring elements (rubber rings) are supported according to the invention. Thus, the solution according to the invention can also be used in conventional couplings and joints for connecting car bodies or complete trains with each other by means of, for example, an automatic or short coupling.
  • The main object of the invention is the transmission of tensile and impact forces or compressive forces, as they occur during operation. The joint arrangement is designed so that tensile and compressive forces are introduced via the tie rod in the system. Subsequently, a transmission of the compressive forces on the front spring plate and the adjacent spring element on the base plate. Tensile forces are transmitted to the base plate via the rear spring plate and the rear spring element. The base plate is bolted to the body frame, so that the force is transmitted into the base frame on the base plate is possible. The inventive arrangement of the spring elements in the pull / push device can be effectively prevented in particular early wear of the spring elements. In particular, the fact that according to the invention support the spring elements in the vertical and horizontal directions, namely, even at high angles of deflection, namely a nearly uniform loading of the spring elements can be achieved. Furthermore, with the solution according to the invention a direct contact between center piece and bearing plate (ie, the inner wall of the provided in the base plate passage opening) prevented in normal operation. Another advantage of the solution according to the invention is to mention that in comparison to the conventional joint arrangements, a larger deflection angle can be achieved. This is achieved in particular by the fact that the Spring elements take over the function of supporting the coupling rod within the passage opening.
  • Advantageous developments of the invention are specified in the subclaims.
  • In a particularly preferred further development it is provided that in the zugstangenseitigen end face and / or in the carriage box side end face of the base plate in each case a recess portion is formed, which extends at least partially along the respective periphery of the provided in the base passage opening and one of the contour of the front or Rear spring element has the following shape, wherein the respective spring element in the associated recess region is flush and is supported thereon. This is a preferred solution to allow the supporting of the pull rod positively enclosing spring elements on the base plate in the vertical and horizontal directions. In detail, it is provided that recess areas are formed at least on one end face of the base plate, which follows the contour of the adjacent spring element. In these recess areas, the respective spring elements is pressed in, so that it is flush with the walls of the recess area. Hereby, a support of the spring elements and thus the pull rod, which is positively surrounded by the spring elements, can be achieved in a particularly effective and effective manner. In other words, the recess areas formed in the respective end faces of the base plate thus form a seat for receiving the respective spring elements. In operation, the spring elements are very stressed components. The contours of these spring elements and the adjacent base plate or formed in the respective end faces of the base plate recess areas in which the respective spring elements are pressed in and flush, should be designed in an advantageous manner so that on the one hand sufficient support is ensured, on the other but enough space is available for the deformation of the elastomeric spring elements during compression or deflection.
  • In particular, it should be mentioned as an advantage of this preferred embodiment that the spring elements provided in the pull / push device on the one hand allow the drawbar to be concealed, and on the other hand - with a suitable choice of shape of the cutout areas - simultaneously effect an integrated return of the drawbar.
  • In a particularly preferred further development of the already mentioned embodiments, it is provided that the passage opening provided in the base plate is designed with respect to the shaping of its opening cross section to a horizontal pivoting of the center piece of the pull / push device extending through the passage opening in a definable angular range, in particular by ± 25 °, thus allowing a deflection of the tie rod connected to the center piece about the Z axis. In particular, the passage opening through the base plate is to be made so large that deflections of the tie rod of up to ± 25 ° about the Z-axis are possible. The base plate and the passage opening formed therein is preferably formed so that the tie rod, when the full rash is reached, applies flat to the correspondingly shaped contour of the base plate. The contours of the spring elements and the adjacent base plate must - as already mentioned - be designed so that on the one hand sufficient support is ensured, on the other hand, but also enough space for the deformation of the rubber elements during compression or deflection is available.
  • The term "Z-axis" in the present specification is understood to mean the axis extending vertically to the drawbar longitudinal direction.
  • As explained above, by providing the recess portions extending at least partially along the respective periphery of the through hole provided in the base plate at the tie rod side end face or at the carriage box side end face of the base plate in which the respective spring member is flush, a support of the spring elements and thus reaches the form-fitting surrounded by the spring elements center piece of the pull / push device. Since the center piece supported in this way is fastened to the carriage box-side end of the pull rod, a support of the pull rod in the Y and Z directions is thus also effected. In order to additionally enable a provision about the X-axis, it is provided in a particularly preferred further development of the last-mentioned embodiments that the at least one front spring element and / or the at least one rear spring element at least at their respective pressure plate-side ends each one different from a circular shape Cross-sectional shape, in particular an elliptical, oval or ellipse-like cross-sectional shape, have.
  • As used herein, the term "ellipsoidal cross-sectional shape" means shaping, including, for example, one in their own Elongated circumference truncated ellipse falls, so that the longitudinal sides of the thus trimmed ellipse parallel to each other. It is essential that the cross-sectional shape of the respective spring elements is not exactly circular, ie centrally symmetrical.
  • A spring element having such a different cross-sectional shape from a circular shape, thus preventing rotation of the spring element relative to the base plate when the spring element is flush with the base plate or formed in the respective end faces of the base plate recess areas. In this way, a rotation of the spring elements relative to the base plate can be prevented, is also a rotation of the center piece of the pull / push device on which the spring elements lie flush, and thus a rotation of the drawbar, which is connected at its cart side end with the center piece is excluded. Of course, other solutions are also conceivable here.
  • In a particularly preferred realization of the last-mentioned embodiment, in which the at least one front spring element and / or the at least one rear spring element each have a cross-sectional shape different from a circular shape at least at their respective pressure plate-side ends, an elliptical or elliptical-like cross-sectional shape is associated with the spring elements a horizontally extending major axis and a vertically extending semi-axis provided. As already indicated above, the term "ellipse-like cross-sectional shape" is to be understood as a shape under which, for example, an ellipse truncated in its longitudinal extent falls. In other words, the cross-sectional shapes of the respective spring elements can also have a rectangular shape, wherein the respective opposite shorter sides of the rectangle are formed as semicircles. However, this embodiment is to be understood that any cross-sectional shape is conceivable to allow a caused by the shaping of the spring element resetting the center piece of the push / push device about the X-axis, when the spring element on the base plate or in. In the recesses formed flush with the end faces of the base plate.
  • To on the one hand to prevent twisting of the drawbar or the center piece of the pull / push device relative to the spring elements in an effective manner, and on the other hand to achieve a provision of the tie rod, it is provided in a particularly preferred further development that the at least one front Spring element and the at least one rear spring element each have a through hole, in particular a centrally disposed in the respective spring elements through hole through which each of the center piece of the pull / push device extends, wherein the formed in the front spring element through hole and / or in the rear Spring element formed through hole each having a different cross-sectional shape of a circular shape, in particular an elliptical, oval or ellipse-like cross-sectional shape. Furthermore, it is preferably provided that the center piece of the pull / push device at least in the sections which extend through the through hole formed in the front spring element and / or through the through hole formed in the rear spring element has a cross-sectional shape corresponding to the respective through hole and there is flush with the inner contour of the corresponding through hole. The inner contour of the spring element and thus also the outer contour of the middle piece are thus elliptical, oval or elliptical, for example, whereby a rotation of the center piece and thus the tie rod relative to the spring elements in a simple but effective manner can be prevented. Thus, the permanent rotation of the tie rod relative to the base plate is also prevented and instead achieved a provision. Of course, other shapes are also conceivable for the through holes formed in the respective spring members and for the respective portions of the center piece of the pulling / pushing device extending through the through holes formed in the spring members. However, these shapes should differ from an exact circular shape.
  • In a particularly preferred realization of the last-mentioned embodiment, with which a permanent rotation of the drawbar relative to the base plate can be effectively prevented, it is provided that the through hole formed in the front spring element and / or the through hole formed in the rear spring element each have an elliptical or having elliptical cross-sectional shape with a horizontal major axis and a vertical axis. This is a possible realization, wherein the entire pull / push device can be formed against rotation with the help of the contour of the through holes. Of course, other solutions are also conceivable here.
  • In a further, although partially known from rail vehicle technology further development is provided that the at least one front spring element and the at least one rear spring element between the respective spring plates and the base plate are biased in tensile / impact direction. Thus, the occurring during the transmission of tensile and impact forces event sequence can be pre-set and set exactly. In particular, a backlash-free response of the spring elements provided in the joint arrangement can be achieved.
  • In the following a preferred embodiment of the present invention will be explained in more detail with reference to the drawings.
