Definitions
- the invention is based on a support, which is arranged between a car body and a chassis, in particular a bogie of a rail-bound vehicle, according to the preamble of claim 1 has a pendulum support between the chassis and the car body and on which an upper , Supported as a rolling curve joint articulated the Wagenka ⁇ boxes.
- Such a support is known from DE-PS 833 745.
- the rolling curve joint is formed by two rolling surfaces lying on top of one another on the car body and on the pen support, the rolling surface on the car body being a flat surface and the rolling surface on the pendulum support being a spherical surface.
- Lateral guides between the car body and the pendulum support ensure that, in the case of a horizontal relative movement between the car body and the chassis, the pendulum support does not move on the flat rolling surface of the car body, but rolls with its spherical rolling surface on the flat rolling surface .
- a disadvantage of the known support is that the two rolling surfaces only touch punctually and therefore the material is exposed to high surface pressure. This can lead to rapid wear and malfunction of the rolling motion between the two rolling surfaces. It also allows the well-known
- a rolling curve joint with a spherical rolling surface on the pendulum support and a flat rolling surface on the chassis is also provided between the pendulum support and the chassis.
- the two spherical rolling surfaces on the pendulum support have a common center.
- the invention has for its object to develop a support with the features from the preamble of claim 1 so that the wear on contacting rolling surfaces is reduced.
- the pendulum support and the car body are connected to one another with two pairs of rolling surfaces via a type of universal joint.
- One pair of rolling surfaces is located between the second support part and the car body and the other pair of rolling surfaces is located between the second support part and the first support part.
- At least one rolling surface of a pair of rolling surfaces is a cylindrical surface.
- the other rolling surface can also be cylindrical, but it is preferably flat. In any case, there is a linear support between the two rolling surfaces of a pair of rolling surfaces, whereby the surface pressure on the materials is significantly reduced compared to a punctiform support.
- the rolling movement when the pendulum support is pivoted in a plane which is perpendicular to the surface lines of a cylindrical rolling surface of the one pair of rolling surfaces can now easily be different than when the pivot support is pivoted in a plane which is perpendicular to the surface lines ⁇ ner cylindrical rolling surface of the other pair of rolling surfaces.
- the rolling surfaces are considered, for example Curvature or designed differently with regard to the position of its central axis.
- the cylindrical rolling surfaces are then arranged in a rotationally secure manner with respect to the car body or chassis, so that the conditions always remain largely the same.
- the surface lines of the at least one cylindrical rolling surface of the one pair of rolling surfaces run in the longitudinal direction of the chassis or the car body.
- the at least one cylindrical rolling surface of the other pair of rolling surfaces then naturally runs vertically, that is to say in the transverse direction of the chassis or the body of the car.
- a relative movement between the car body and the bogie only in the longitudinal or only in the transverse direction is then only possible by rolling the two rolling surfaces of one pair of rolling surfaces against one another. It should be pointed out here that when driving straight ahead the longitudinal direction of the chassis and the body of the vehicle correspond and coincide with the direction of travel. When cornering, there is a small angle between the longitudinal direction of the car body and the longitudinal direction of the chassis.
- a cylindrical rolling surface of a pair of rolling surfaces in particular the cylindrical rolling surface of each rolling surface pair, is of circular cylindrical design, as is the case in the configurations according to claims 4 and 5.
- one of the rolling surfaces of a pair of rolling surfaces is a flat surface.
- the entire pendulum support is fixed against rotation with respect to the chassis or with respect to the car body and can be rotated about its longitudinal axis with respect to the other part.
- parts of the pendulum support are not twisted against each other, but the pendulum support in its entirety relative to the car body or the chassis.
- at least one pair of rolling surfaces is designed in such a way that the distance between the body and the chassis is increased during a rolling movement from the central position of the pendulum support. The consequence of this is that, due to the weight of the car body, a restoring force occurs when the pendulum support is pivoted.
- a restoring force is desired in the case of rail vehicles, at least for a relative movement between the body and the bogie in the transverse direction.
- Claims 11 to 13 relate to a favorable arrangement of guide elements against displacement of the two rolling surfaces of a pair of rolling surfaces and against rotation of two components of the pendulum support or one of the components of the pendulum support and the car body or the chassis against one another.
- the pendulum support comprises a third support part which is arranged between the first support part and the chassis.
- a rolling curve joint with rolling surfaces that touch in a linear manner, at least one of the two rolling surfaces touching each other being cylindrical.
- the second support part and the third support part have the same shape.
- an anti-rotation device is provided between the first support part and the second support part and between the first support part and the third support part.
- the entire pendulum support is thus secured against rotation with respect to the chassis by a further anti-rotation device between the third support part and the chassis.
- a design according to claim 18 ensures that the distance between the body and the chassis increases when the pendulum support swings out of its central position. This gives the restoring force already mentioned above.
- Figure 1 is a vertical section through the middle of the pendulum support through the embodiment
- FIG. 2 shows a section along the line II-II from FIG. 1.
- a part of a bogie 10 and a part of a car body 11 of a rail vehicle can be seen in the figures. Between the bogie 10 and the car body 11, two pendulum supports are arranged, one of which is shown in the figures.
- the overall pendulum support provided with the reference number 12 consists of three parts, namely a central, first support part 13 and a second support part 14, which is arranged between the first support part 13 and the car body 11, and a third support part 15, the is arranged between the first support part 13 and the bogie 10.
- the third support part 15 has essentially the shape of a cylinder segment with a circular-cylindrical rolling surface 16 facing the bogie 10, which lies linearly on a flat rolling surface 17 of the bogie 10 and can roll on this surface.
- the radius of the circular cylindrical rolling surface 16 is as large as the distance that the car body 11 has from the bogie 10 when the pendulum support 12 is in its central position. lung.
- the distance between the contact line 18 of the two rolling surfaces 16 and 17 and the central axis 19 of the circular cylindrical rolling surface 16 is twice as large as the distance between the contact line 18 and the horizontal central plane 20 between the bogie 10 and the car body 11 and the thus coinciding center plane of the pendulum support 12.
- the third support part 15 is framed by a cheek 21 of the bogie 10 and is thereby secured against rotation with respect to the bogie 10. Movement of the third support part relative to the bogie 10 in a direction perpendicular to the generatrices of the circular cylindrical rolling surface 16 is prevented by one or two teeth 22 which are firmly seated on the third supporting part 15, project beyond its rolling surface 16 and each into a recess 23 protrude into the bogie 10.
- the flanks of the teeth 22 begin at the rolling surface on which the teeth are seated, end in a tooth tip and are circular involutes on average.
- the profile of a tooth 22 thus corresponds to an involute toothing.
- the depressions 23 have a trapezoidal cross section.
- the tooth flanks and the flanks of the depressions touch each other in a linear manner.
- roller sliding takes place between the teeth 22 and the recesses 23. If the rotation 22 between the support part 15 and the bogie 10 is also ensured by the teeth 22, the cheek 21 of the bogie 10 can be dispensed with.
- the third support part 15 has a flat rolling surface 25 which is flanked by two lateral cheeks 26 in a direction parallel to the surface lines of the circular cylindrical rolling surface 16.
- the second support part 14 has the same shape as the third support part 15, but is rotated by 180 ° relative to the support part 15 about an axis running parallel to the central axis 19. built. Accordingly, it has a rolling surface 27 identical to the circular cylindrical rolling surface 16 of the support part 15, a flat rolling surface 28 facing the first support part 13 and two lateral cheeks 29. The central axis of the circular cylindrical rolling surface 27 falls in the middle position of the pendulum support 12 with the contact line 18 between the rolling surfaces 16 and 17 together. With two teeth 22, the support part 14 engages in two recesses 23 of the car body 11.
- the car body 11 lies with a flat rolling surface 30 on the circular cylindrical rolling surface 27 of the support part 14. In the middle position of the pendulum support, the line of contact between the rolling surfaces 27 and 30 coincides with the central axis 19 of the rolling surface 16.
- the middle, second support part 13 has the shape of a biconvex cylindrical lens and has two circular cylindrical rolling surfaces 31 and 32, which have the same curvature and of which the rolling surface 31 has the flat rolling surface 25 of the supporting part 15 and the rolling surface 32 flat rolling surface 28 of the support member 14 touches.
- the central support part 13 is formed symmetrically with respect to a central plane running parallel to the surface lines of the rolling surfaces 31 and 32, which coincides with the plane 20 in the central position of the pendulum support 12.
- the cheeks 26 and 29 of the support parts 15 and 14 frame the central support part 13 on the end faces, so that a rotation lock between all support parts is ensured.
- the surface lines of the circular cylindrical rolling surfaces 31 and 32 of the support part 13 run perpendicular to the surface lines of the circular cylindrical rolling surfaces 16 and 27. For example, the surface lines of the rolling surfaces 16 and 27 in the longitudinal direction of the
- Chassis 10 and the surface lines of the rolling surfaces 31 and 32 are perpendicular to the longitudinal direction of the bogie 10.
- the central axes of the two rolling surfaces 31 and 32 of the support part 13 each lie far beyond the central plane of the supporting part 13, so that in the central position of the pendulum support the distance between the line of contact of a circular cylindrical rolling surface 31 or 32 and the central axis of this rolling surface is significantly greater than the distance between the contact line and the center plane, which at the same time also forms the center plane between the bogie 10 and the car body 11 when the pendulum support is not deflected.
- the support part 14 could also be secured against twisting by cheeks of the car body 11, provided that this function is not achieved by the teeth 22 on the support part 14, which slide by engaging recesses 23 in the car body 11 the surfaces 27 and 30 prevent each other, transmits.
- the pendulum support and the bogie 10 and the car body 11 are shown with solid lines in a state in which the pendulum support assumes a central position and is not pivoted. If a force now acts on the car body 11 in the direction of arrow A, the car body 11 is displaced in the direction of arrow A with respect to the bogie 10, the path being limited by a stop with a large spring constant. During the displacement, the two surfaces 16 and 17 of the support part 15 and the bogie 10 and the two surfaces 27 and 30 of the support part 14 and the car body 11 roll on each other.
- the pendulum support 12 gets into one Inclined position, the distance between the car body and the bogie being increased, that is to say the car body being raised, on account of the dimensions chosen for the curvatures of the circular cylindrical rolling surfaces 16 and 27 and the minimum distance between the car body 11 and the bogie 10.
- the distance between the car body and the bogie being increased, that is to say the car body being raised, on account of the dimensions chosen for the curvatures of the circular cylindrical rolling surfaces 16 and 27 and the minimum distance between the car body 11 and the bogie 10.
- the body 11 is raised.
- the car body 11 moves with respect to the bogie 10, which at the same time has a component in the transverse direction and in the longitudinal direction, all of the rolling surfaces roll onto one another.
