Abstract
Abstract of the Disclosure:
Side sills for two-axle railroad freight cars transmit horizontal buffer forces, accept a vertical cargo load and support devices for mounting axles. The object of the invention was to provide a side sill for two-axle railroad freight cars which was formed of simple, economically produc-ible components, which allowed a simple and economical configuration of required cross members, which reduced noise emission of a running gear and which improved aerodynamic properties in the region of an underframe. Therefore, the side sill of the invention is formed of a single metal sheet of uniform wall thickness being bent a number of times and extending from buffer beam to buffer beam of the railroad freight car. The side sill has a joint-free construction in cross-section. An upper longitudinal end of the side sill has three steps, wherein an uppermost step forms a loading plane, a central step forms a support for a floor covering and a bottom step forms a support for cross members of the railroad freight car.

Description
Mp.-Nr. 93/717 SIDE SILLS FOR TWO-AXLE RAILROAD FREIGHT CARS
Backaround of the Invention:
Field of the Invention:
The invention relates to side sills or outer longitudinal supports for two-axle railroad freight cars or wagons, which transmit horizontal buffer forces, accept a vertical cargo load and support devices for mounting axles.
Side sills for two-axle railroad freight cars generally are formed of a continuous rolled, bent or welded section with which downwardly-projecting, fishbellied reinforcements in the form of trussed girders or sheet-metal profiles are disposed between the axles. In order to accommodate the axles, sheet-metal axle guides are welded to the known side sills and secured by means of axle-guide straps which reach around the axle guides on the inside and are welded-on underneath the side sills. Those known side sills are ;
constructed from a multiplicity of separate components, which must be welded together in an involved manner. Another disadvantage with such known side sills is the requirement for accurate insertion of cross members, which must be butt-welded to the side sills from the inside.

~ 21~6~1 Mp.-Nr. 93/717 In accordance with a further feature of the invention, the upper longitudinal end of the side sill has three steps, namely an uppermost step forming a loading plane, a central step forming a suppor~ for a floor covering and a bottom step forming a support for cross members of the railroad freight car. This stepped construction of the side sill in its upper region allows simple insertion of the floor covering and the cross members of the railroad freight car with great freedom with regard to dimensional accuracy and allows them to be secured by simple means and in an economical manner.
In accordance with an added feature of the invention, the side sill is of continuous construction with the same overall height over the axles towards the buffer beam. The "skirts"
of the side sill, which cover the axle regions of the rail-road freight car, provide a marked reduction in the noiseemission of the running gear. The aerodynamic characteris-tics, in particular air resistance and wind noise, are reduced.
In accordance with an additional feature of the invention, there are provided downwardly open cutouts in the side sills in the region of the axles for accommodating axle-box cases of the axles, the cutouts being closable at the bottom in a known manner by means of an axle-guide web, and slide-ways being disposed on vertical e~ges of the side sills at the cutout to provide longitudinal stops for the axle-box cases.

Referring now to the figures of the drawing in detail and first, particularly, to Fig. 1 thereof, there is seen a side sill or outer longitudinal support 1 according to the inven-tion on a two-axle sliding-side wagon or car. It is seen that between buffer beams 2 of the railroad freight car, the side sill 1 is formed of a single metal sheet of uniform cross-section which is bent a number of ti~es, and that only - -in the vicinity of the buffer beams 2 of the railroad freight car, in the region of axles 3 and in the region of suspension links 4, is it provided with cutouts.
.. ::
A~ is seen in Figs. 3, 4 and 5, the side sill 1 has an upper ~ ;
longitudinal side at which it is bent to form three steps, ~-i namely an uppermost step 6 lying in a loading plane of the railroad freight car and framing that plane toward the side, a central step 7 forming a support for a floor covering 8 and a bottom step 9 being provided to support required cross members 10 of an underframe or chassis of the railroad ~reight car. A vertical region 11 of the side sill 1, which has a horizontal bend 12 at its lower longitudinal side, extends with the same cross section beyond the axles 3 and ~
into the vicinity of the buffer beams 2. In the vicinity of -the buffer beams 2, the side sill 1 is cut out from below and extends to the level of the buffer beams 2 with a taper, as is seen in Figs. 1 and 4. This taper of the side sill 1 is achieved by punching or cutting out the side sill 1. Cutouts ~ 211 g 611 Mp.-Nr. 93/717 13 which are open at the bottom are provided in the region of the axles 3 to accommodate axle-box cases 1~ of the axle 3, which are seen in Figs. 1, 2 and 3. These cutouts 13 can be closed by axle-guide webs 15. Slide-ways 16 are secured on vertical edges of the sills 1 at the cutout 13 to provide longitudinal stops for the axle-box cases 14. Openings 17 in the vertical region 11 of the side sill 1 at the level of the links 4 serve for the inspection of the brake system. Leaf springs 18 are disposed vertically on both sides of the cutout 13, on the inside of the side sill 1.
These leaf springs 18 are force-lockingly clamped-in at the top on the side sill 1 and, in the region of the axle-box cases 14, they lie at a defined spacing in front of the side sill 1 and serve to transmit transverse forces between the underframe or chassis and the axle-box cases 14.
