Den foreliggende bremse angår en sikkerhedsbremse til skinnevogne, omfattende et chassis, dér med to på ^ hver sin fælles aksel anbragte hjulpar bevæges op og - ned ad en skrå skinnebane ved hjælp af en fra skinne- l : ... - banens øverste punkt til vognen tilspændt wire. Bremsen er af den art, der vil bevirke en bremsning, såfremt vognens hastighed overskrider en forud fastsat værdi.'The present brake relates to a safety brake for rail cars, comprising a chassis, where two pairs of wheels mounted on each common axle are moved up and down a sloping track by means of a rail: ... - the top of the track to wagon tightened wire. The brake is of the kind that will cause a brake if the speed of the vehicle exceeds a predetermined value. '

Hvis den udspændte wire brister, eller hvis den mo-‘ tor, der trækker wiren, fejler, vil skinnevognen med ' stadig voksende hastighed af tyngdekraften blive bevæget ned langs skinnebanen. Det er derfor vigtigt at skinnevognen forsynes med en bremse, der f.eks. kan være af den ovennævnte art. Ved opfindelsen tilsigtes det at angive en bremse af denne art, der er meget éhkel i sin udformning og samtidig driftsikker.If the tensioned wire breaks or if the motor pulling the wire fails, the rail car will be moved down the rail track at an ever increasing speed of gravity. Therefore, it is important that the rail car is provided with a brake, which e.g. may be of the above type. It is an object of the invention to provide a brake of this kind which is very simple in its design and at the same time reliable.

Ifølge opfindelsen er der til den ene af de med hjulene roterende aksler fastgjort en radialt udstående arm, der bærer en i forhold til armen drejelig krog eller et lignende gribeorgan, og at der i vognens chassis er lejret et bremseorgan, med hvilket gribeorganet på grund af centrifugalkraften går i indgreb, hvis vognens fart overstiger den forud fastsatte værdi.According to the invention, a radially protruding arm is attached to one of the axles rotating with the wheels, which carries a pivotable hook or similar gripping means and that a braking means is mounted in the car chassis with which the gripping means due to the centrifugal force engages if the vehicle speed exceeds the predetermined value.

Ved denne udformning med det direkte på den roterende aksel lejrede gribeorgan opnår man tinder anvendelse af få og enkle maskinelementer en hurtig og effektiv bremsning i tilfælde af løbsfckørsel. Den voksende hastig-hed af hjulakslen vil medføre, at gribeorganet går i indgreb med bremseorganet, der kan være udformet således, at det går i indgreb med den pågældende hjulaksel, så hjul-' parret blokeres. Dette medfører, at yogaens fart bremses.In this design, with the gripping means directly mounted on the rotating shaft, the use of a few and simple machine elements is obtained, a rapid and effective braking in case of run-off. The increasing speed of the wheel axle will cause the gripper to engage the braking means, which may be designed to engage the particular axle so that the wheel pair is blocked. This causes the speed of yoga to slow down.

Ved lange og/eller stærkt skrånende skinnebaner og/ eller, når skinnevognen er tung, kan det være ønskeligt at opnå en større afbremsning af vognen end den, der opnås ved et blokeret hjulpar.For long and / or heavily sloped rail tracks and / or when the rail car is heavy, it may be desirable to achieve greater braking of the car than that achieved by a blocked wheel pair.

Det er derfor Ifølge opfindelsen fordelagtigt, at bremseorganet udgøres af en wire, hvis ender er således fastgjort til den ene ende af i hvert fald en i chassi-1‘ set drejeligt lejret arm, der af en fjeder fastholdes i , 2 142231 en udgangsstilling, men ved'gribeorganets træk i wiren svinges til en stilling, hvor armen ligger an mod i hvert fald den ene af banens to skinner. Herved udformes bremsen ifølge opfindelsen £å en enkel måde som skinnebremse, idet armen presses mod f.eks. undersiden af i hvert fald den ene skinne, hvorved man kan opnå en mere effektiv friktionsafbremsning af vognen* Bremsearmen kan eksempelvis være en omtrent på tværs af vognen liggende arm, hvis ender ved træk i bremsewiren trykkes mod indersiden af begge skinner*Accordingly, it is advantageous according to the invention that the braking means is constituted by a wire, the ends of which are thus fixed to one end of at least one arm, which is rotatably mounted in the chassis-1 ', which is held by a spring in a starting position, but by the pull of the gripper in the wire, it is pivoted to a position where the arm rests at least one of the two rails of the web. Hereby the brake according to the invention is designed in a simple manner as a rail brake, the arm being pressed against e.g. the underside of at least one rail, thereby providing a more efficient friction braking of the carriage * The brake arm may, for example, be an arm which is approximately transverse to the carriage, if the ends of the brake wire are pressed against the inside of both rails *

Bremsen ifølge opfindelsen skal i det følgende forklares nærmere i forbindelse med tegningen, hvor fig. 1 viser en skinnevogn med en sikkerhedsbremse ifølge opfindelsen, set fra oven, fig. 2 samme, set fra den ene ende, og fig. 3 et snit langs linien A-A i fig. 1.The brake according to the invention will now be explained in more detail in connection with the drawing, in which fig. 1 is a top view of a rail car with a safety brake according to the invention; FIG. 2 shows one end, and FIG. 3 is a section along the line A-A of FIG. First

Den på tegningen viste skinnevogn omfatter et chassis i form af en ramme 1, der bærer to hjulaksler 2 og 3. På den ene aksel 3 er fastgjort to bæreplader. Disse bæreplader roterer med de ligeledes til akslen 3 fastgjorte kørehjul 4. Til bæreplademe er uden for akslen 3 drejeligt fastgjort mindst et gribeorgan 5, der ved den viste udførelsesform er krogformet. I chassisrammen 1 er udspændt en wire 6 på en sådan måde, at et af gri-beorganerne 5 vil gribe fat i wiren, hvis kørehjulenes omdrejningshastighed overstiger en forud fastsat værdi.The rail car shown in the drawing comprises a chassis in the form of a frame 1 carrying two wheel axles 2 and 3. On one axle 3 are attached two support plates. These supporting plates rotate with the drive wheels 4 also attached to the shaft 3. The supporting plates are pivotally attached outside the shaft 3 at least one gripper member 5 which is hook-shaped in the embodiment shown. In the chassis frame 1, a wire 6 is stretched in such a way that one of the gripping means 5 will grip the wire if the speed of rotation of the drive wheels exceeds a predetermined value.

Herved vil akslen 3 blive fastholdt, således at kørehjulenes 4 rotation på en ikke vist skinnebane hindres, og vognen bremses.Hereby the shaft 3 will be held so that the rotation of the driving wheels 4 on a rail track not shown and the carriage is braked.

Enderne af wiren 6 er fastgjort til den ene ende af hver sin bremsearm 7. De to bremsearme 7, der er svingbart lejret i chassisrammen 1, holdes af en fjeder 8 i udgangsstilling, hvor armene ikke påvirker kørselen. Ved gribeorganets 5 træk i wiren 6 vil armene 7 imidlertid blive således drejet, at armene selv eller ved den viste udførelsesform exeenterskiver 9 med friktionsforøgende riflet overflade presses mod indersiden af skinnebanens to skinner.The ends of the wire 6 are attached to one end of each of their brake arms 7. The two brake arms 7, which are pivotally mounted in the chassis frame 1, are held by a spring 8 in the starting position where the arms do not affect the travel. However, at the pull of the gripper member 5 in the wire 6, the arms 7 will be rotated such that the arms themselves or, in the embodiment shown, friction-increasing discs 9 with friction-increasing grooved surface are pressed against the inside of the two rails of the track.

Eventuelt kan den ene bremsearm 7 udelades, idet den pågældende ende af wiren 6 da fastgøres til chassisrammen 1.Optionally, one of the brake arms 7 may be omitted, the respective end of the wire 6 being then secured to the chassis frame 1.
