Definitions

  • the invention relates to a support device for the lateral elastic support of the body of a rail vehicle relative to its drive, in particular bogie, comprising a fixed slide with a flat slide surface and an opposite, designed as a leaf spring with a convex slide surface resilient slide, parallel at its first longitudinal end about an axis is pivotable to the flat sliding surface and is displaceably mounted parallel to the flat sliding surface at its second longitudinal end.
  • a fixed slide plate is generally provided, which is supported on a spring-loaded slide plate.
  • the spring-loaded sliding plate is provided with spring elements in the known designs, which allow vertical deflection of this elastic sliding plate to a limited extent. Due to the arrangement of a spring element for the vertical flexibility of a slider, the arrangement of additional guides is required here so that the slider is guided exactly when the bogie moves relative to the body.
  • a device is known from US Pat. No. 1,958,188 which comprises fixed and resilient sliding pieces lying opposite one another and is used for the lateral elastic support of the car body of rail vehicles with respect to its running gear.
  • the resilient slider is designed with a convex sliding surface and consists of a leaf spring supported only on its longitudinal ends, which is free of longitudinal play and is articulated on one of its longitudinal ends.
  • the object of the invention is to avoid these disadvantages in the case of a lateral, rigid body support of the type mentioned at the outset, to achieve a uniform load on the wheels, the support being formed without costly components, and to have a direct-acting rotation inhibition between the body and the bogie achieve.
  • This object of the invention is achieved in that the articulated mounting of the first longitudinal end secures the resilient sliding piece against displacement in both longitudinal directions and that the second longitudinal end is loaded only by frictional forces parallel to the flat sliding surface.
  • the resilient slider is advantageously formed only from a leaf spring, the side facing the fixed slider also the sliding surface for supporting the fixed slider. forms. Costly components are thus avoided.
  • the longitudinal play-free mounting of the resilient slider is possible with simple means.
  • the resilient slider (leaf spring) is formed with a cross-sectionally parobolically decreasing cross-sectional height from about its length center toward both supports. Due to the parabolic design of the sheet thickness profile of the elastic slide, a maximum elasticity of the elastic slide is given for a given overall length. Another advantage of the parabolic design of the spring leaf of the elastic slider is that the leaf spring can be placed in front and thus a higher load can be made with the same material quality.
  • the resilient slider (leaf spring) is rolled up at its articulated end to form a bearing eye.
  • This configuration of the leaf spring advantageously achieves a simple component and avoids the arrangement of additional bearing elements.
  • the bearing eye of the resilient slider (leaf spring) is expediently formed by rolling the leaf spring downward.
  • the free end of the resilient slider is longitudinally displaceable and laterally guided with play on a slider. This free support in the longitudinal direction of the resilient slider enables a compression-free longitudinal displacement of the free end of the slider when it is deflected.
  • an end stop limiting the deflection is arranged at a distance below it.
  • the elastic support according to the invention consists of a fixed and a resilient slider.
  • the fixed slider is not shown in the drawing.
  • This fixed slide consists, as is common in known designs, of a horizontally arranged slide plate on its underside, the slide surface of which may be equipped with an additional covering with high wear resistance or low coefficient of friction.
  • the resilient slider 1 is formed from a leaf spring, the. upward sliding surface is substantially convex. In its resiliently effective area, the resilient slider is designed parabolically to both longitudinal ends with a decreasing cross-sectional height. At one of its longitudinal ends, the resilient slider is rolled up to form a bearing eye 2, this bearing eye 2 being formed by rolling the resilient slider 1 downward.
  • the resilient slider 1 is articulated in bearings 4 by means of a bolt 3 arranged transversely to the longitudinal axis of the vehicle. At its other free longitudinal end, the resilient slider 1 is slightly bent and rests with its underside on a slider 5.
  • the slider 5 is provided with lateral guides 5a which guide the resilient slider 1 laterally with play.
  • an end stop 6 is provided at a distance below it, which limits the deflection of the resilient slider 1.
  • the resilient slider is expediently arranged on the bogie or the running gear of the rail vehicle, while the fixed slider is attached to the car body.
  • the sliding surface 1 a of the resilient slider 1 can be made flat in the middle in a short area without the spring characteristic of the resilient slider being adversely affected thereby.
