DE939932C - Bogie for fast moving rail vehicles with swinging guide pivot - Google Patents

Description

The patent 933 690 relates to a bogie for rail vehicles with separate suspension of the Wheel axles and the car body, which is directly on the side of the H-shaped, inside mounted bogie frame is supported vertically guided box springs.

According to the main patent, the car body is on the side with support plates and the heads of the Box springs are provided with support plates that are large enough to act as a sliding surface for the in

horizontal level occurring shocks of the vehicle to dampen, and the car body with The guide pivot connecting the bogie is mounted in the bogie frame so that it can swing out. The pivot pin attached to the car body is supported by rubber MetaH rails in the horizontal plane is resiliently supported in such a way that it allows only a small amount of play in the longitudinal direction of the vehicle, because the rubber-metal rails are then subjected to pressure, in the vehicle transverse direction ao

tujig, 'where they are claimed to be thrust, however can swing out with the desired larger game.

The smooth running of a rail vehicle. , is favorably influenced if the car body '' ... 'swing in the longitudinal direction of a bigger game for the training has over the bogie frame To make this happen., according to the invention between pivot and bogie frame a ίο is 90 ⁰ offset, Second pair of rubber-metal rails arranged so that they are loaded by the longitudinal forces on thrust and thus result in a greater spring deflection in this direction as well the resilient play in the longitudinal and transverse direction of the vehicle is made up of the springs resulting from the compressive stress of one pair of rubber-metal rails and the shear stress of the other pair of rubber-metal rails. that the pivot bearing by ..two ^ opposite rubber-metal rails against one of these.

surrounding frame is supported, which is supported by two more to the first mentioned rubber-metal rails by 90 ' ⁰ and attached to the outside of the frame with the bogie frame. connected is.

An example embodiment of the invention is shown schematically in the drawing. On a frame 20 are inside on two opposite sides Sides two rubber-metal rails 11 and 11 'attached, with which the bearing 9' for the guide pivot is resiliently supported so that these rails in the vehicle longitudinal direction only Allow a small amount of play, but swing in the transverse direction of the vehicle with a greater amount of play can. A second pair of rubber-to-metal rails 21 and 21 'are at 90' degrees' to the rubber-to-metal rails 11 and ii 'offset - on the outside of the frame 20 attached. The rubber-metal rails 21 and 2i 'are on their outer surface with the bogie frame S connected.

The mode of operation of the arrangement according to the invention is as follows :. The. on the pivot bearing 9 'Forces acting in the longitudinal direction of the vehicle are transmitted via the rubber-metal rails, which are subjected to pressure 11 and 11 '' on the frame 20 and transferred from this 'via the rubber-metal rails 21 and 21' to the bogie frame 5, wherein the rubber-metal rails 21 and 21 'are loaded on thrust and a Displacement of the frame 20 up to the limit stops provided on the bogie frame 5 Allow 22 and 22 'or 23 and 23'.

"Forces occurring in the transverse direction of the vehicle: result Shear stresses "of the rubber-metal rails 11 and 11 'and resilient play up to Stop of the pivot] agers 9 'on the frame 20, from which it is via "the rubber-metal rails 21 and 2i 'are transferred to the bogie frame 5. Longitudinal and transverse directions of the frame 20 can also be swapped; then the longitudinal vibrations of the vehicle as thrust ■ forces through the rubber-metal rails 11 and 11 '. And the transverse vibrations as shear forces through the rubber-metal rails 21 and 21 ' - wear.

The inventive design of the bearing of a pivot pin 9 is not limited to that the guide pivot is mounted in the bogie frame 5 below the axle spring support level is. The storage according to the invention can be used on trunnions in any Height are arranged in the bogie frame, regardless of whether the bogie frame is inside or is supported outside the wheels.
