Vlečna naprava za priklopna vozilaTowing device for trailers
Izum zadeva vlečno napravo za priklopna vozila z naletno zavorno napravo, ki pri relativnem gibanju med vlečnim drogom, povezanim s krogelno sklopko, in vlečnim ojesom preko preusmernega vzvoda deluje na zavorno drogovje, in z od naletne zavorne naprave neodvisno delujočim ročnim zavornim vzvodom, ki preko sojemala deluje na preusmerni vzvod, pri čemer sta preusmerni vzvod in ročni zavorni vzvod uležiščena skupaj na tečaju na vlečnem ojesu.The invention relates to a towing device for trailers with an impact braking device which, on relative movement between the coupling rod connected to the ball coupling and the drawbar, acts on the brake pole via a retractable lever, and with a manually operated, manually operated, lever operated on the launching device. The clamp acts on the reversing lever, with the reversing lever and the manual brake lever mounted together on the hinge on the drawbar.
Tovrstne vlečne naprave za priklopna vozila so znane v raznih izvedbah. Ker je sojemalo med ročnim zavornim vzvodom in preusmernim vzvodom izvedeno kot pod skupnim tečajem na enem od obeh vzvodov zasnovano podaljšanje, ki je bočno zapognjeno -in sodeluje z ustreznim podaljškom drugega vzvoda, imajo pri znanih vlečnih napravah opraviti ne le z zmanjšanjem odmika od tal, temveč tudi s potrebo po tem, da z dodatno talno oporo poskrbijo, da pri odstavitvi priklopnega vozila, odpetega od sklopilne krogle vlečnega vozila, in pri tem na tla spuščenem vlečnem ojesu ne more priti do nehotenega premika zavornega drogovja, predvsem ne do sprostitve ročnega zavornega vzvoda.Such trailers for trailers are known in the various embodiments. Since the coupling between the manual brake lever and the diversion lever is designed as a joint hinge on one of the two levers designed to be laterally folded -and interact with the corresponding extension of the other lever, not only by reducing the ground clearance, but also with the need for additional ground support to prevent the trailer from being pulled away from the coupling ball of the towing vehicle and thereby to prevent the brake rod from moving downwards on the ground, in particular by not releasing the parking brake. leverage.
Izum temelji na nalogi, tako nadalje razviti vlečno napravo zgoraj opisane vrste za priklopna vozila, da bo hkrati s povečanim odmikom od tal dobljena zanesljiva namestitev zveze med ročnim zavornim vzvodom in preusmernim vzvodom.The invention is based on the task of further developing the towing device of the type described above for trailers in order to obtain a reliable connection between the manual brake lever and the reversing lever with increased ground clearance.
Rešitev tako zastavljene naloge po izumu je značilna po tem, da je sojemalo uležiščeno na tečaju kot tudi nezasučno povezano z ročnim zavornim vzvodom in da sojemalo zagrabi v območju med tečajem in naležno ploskvijo za vlečni drog na preusmernem vzvodu.The solution of such a task according to the invention is characterized by the fact that the saddle is mounted on the hinge as well as non-rotationally connected with the handbrake lever and that the grapple is caught in the area between the hinge and the contact surface for the drawbar on the retractable lever.
Z nadaljnjo spopolnitvijo po izumu znane vlečne naprave je dosežena prednost, da se po eni strani s sojemaloma, prioblikovanima na ročnem zavornem vzvodu ali preusmernem vzvodu, odpravi zmanjšanje odmika od tal in po drugi lahko sojemalo zaščiteno spravimo v območju ohišju podobne izvedbe vlečnega ojesa, tako da se lahko odrečemo dodatnim ukrepom proti nehotenemu premikanju zavornega drogovja.By further upgrading the known drawbar according to the invention, it is advantageous to eliminate the reduction of ground clearance on the one hand with the couplers formed on the hand brake lever or the reversible lever, and on the other hand, the buckle can be secured securely in the housing area of a similar design of the drawbar. that additional measures can be taken to prevent the brake rod from moving accidentally.
Po nadaljnjih značilnostih izuma je sojemalo zasnovano kot poseben sestavni del, tečaj pa razporejen v po načinu ohišja podaljšanem delu vlečnega ojesa, ki oklepa preusmerni vzvod in sojemalo.According to further features of the invention, the handle is designed as a separate component, and the hinge is arranged in a housing-like extension of the drawbar that encloses the diversion lever and the handle.
Na risarski predstavitvi je predstavljen izvedbeni primer vlečne naprave po izumu, pri čemer kažeta sl. 1 vlečno napravo v vzdolžnem prerezu in sl. 2 presek čez vlečno napravo po rezni črti II-II v sl. 1.The drawing shows an embodiment of a towing device according to the invention; 1 is a longitudinal cross-sectional view of the towing device; and FIG. 2 is a cross-sectional view of the towing device along the cutting line II-II in FIG. 1.
Na skicah predstavljeni izvedbeni primer kaže vlečno napravo z ojesno cevjo 1, ki je pritrjena na voznem okviru tu črtkanopikčasto nakazanega priklopnega vozila 2 in v svojem prednjem delu sprejme ležiščno ohišje 3 za naletno zavorno napravo, ki nadalje obsega vlečni drog 4. Na prednjem koncu tega vlečnega droga 4 je s pomočjo vijačnega sornika 6 pritrjena krogelna sklopka 5, s katere pomočjo lahko priklopno vozilo 2 sklopimo z nenarisano sklopilno kroglo vlečnega vozila. Skica sl. 1 nadalje kaže sklopilni vzvod 5a in meh 7, ki na koncu krogelne sklopke 5 vlečni drog 4 tesni proti ležiščnemu ohišju 3 oz. ojesni cevi 1.In the drawings, the exemplary embodiment shows a drawbar device with an axial tube 1 which is attached to the drive frame here by a dotted-pointed trailer 2 and in its front part receives a bearing housing 3 for an oncoming brake device further comprising a drawbar 4. At the front end of this of the drawbar 4, a ball clutch 5 is attached by means of a screw bolt 6, by which the trailer 2 can be coupled to an unmarked coupling ball of the drawbar. Sketch of FIG. 1 further shows a coupling lever 5a and a bellows 7 which, at the end of the ball coupling 5, draw the drawbar 4 against the bearing housing 3 or. axle pipes 1.
Pri zaviranju vlečnega vozila pride zaradi vztrajnosti mase priklopnega vozila 2 do relativnega gibanja med v ojesni cevi 1 razporejenim ležiščnim ohišjem 3 in vlečnim drogom 4. Pri tem se vlečni drog 4 premakne v smeri proti priklopnemu vozilu 2 v ojesni cevi 1 in s svojim zadnjim koncem zadene ob preusmerni vzvod 8, katerega naprej ukrivljeni zgornji krak 8a je razporejen v notranjosti ojesne cevi 1 in ki je zavihtljiv okoli pod ojesno cevjo 1 razporejenega tečaja 9. Na spodnjem vzvodnem kraku 8b preusmernega vzvoda 8 je s pomočjo sklopilnega kosa lOa zgibno priključen prednji konec zavornega drogovja 10. Premiku naletne zavorne naprave zato sledi poteg zavornega drogovja 10 v smeri vožnje, s čimer se aktivira zavora priklopnega vozila 2.When the trailer is braked, due to the persistence of the mass of the trailer 2, relative movement between the axle tube 1 of the bearing housing 3 and the drawbar 4 occurs. The drawbar 4 moves in the direction of the trailer 2 in the drawbar 1 and with its rear end. hit by a diversion lever 8 whose forward curved upper arm 8a is disposed in the interior of the hose 1 and which pivots about under the hose 1 of the arranged hinge 9. On the lower lever arm 8b of the diversion lever 8, the front end is articulated via a coupling piece lOa. 10. The displacement of the oncoming braking device is therefore followed by the pulling of the brake rod 10 in the direction of travel, thereby activating the brake of the trailer 2.
Da lahko zategnemo zavoro odklopljenega priklopnega vozila 2, je na ojesni cevi 1 nadalje razporejen ročni zavorni vzvod 11, ki preko sojemala 12 deluje na preusmerni vzvod 8, tako da se pri zavihtitvi ročnega zavornega vzvoda 11 v urnem smislu zavorno drogovje 10 prav tako vlečno aktivira.In order to tighten the brake of the disconnected trailer 2, a manual brake lever 11 is further disposed on the axial pipe 1, which acts on the reversing lever 8 via the handle 12, so that when the manual brake lever 11 is rotated, the brake lever 10 is also towed .
Da lahko ročni zavorni vzvod 11 v njegovem zavornem položaju zadržimo, je le-ta opremljen z zaskočko lla, ki po sl. 1 uprijema v ozobje vskočne plošče 13.In order to retain the handbrake lever 11 in its braking position, it is provided with a latch which, according to FIG. 1 fits into the toothed plate face 13.
Kot najbolje izhaja iz sl. 2, je tečaj 9 uležiščen zasučno v dveh ohišnih stranskih delih la, ki pri izvedbenem primeru ojesno cev 1 podaljšujeta v smeri dol. V prostoru med tema ohišnima stranskima deloma la je s pomočjo ležiščne puše 8c zasučno uležiščen s svojim zgornjim vzvodnim krakom 8a v ojesno cev štrleči preusmerni vzvod 8. Izven enega od ohišnih stranskih delov la služi tečaj 9 nadalje za uležiščenje ročnega zavornega vzvoda 11. Med obema omenjenima deloma je slednjič na tečaju 9 zasučno uležiŠčeno sojemalo 12, ki je na eni strani nezasučno povezano z ročnim zavornim vzvodom 11 in na drugi v območju med tečajem 9 in naležno ploskvijo preusmernega vzvoda 8 za vlečni drog 4 uprijema na preusmerni vzvod 8. Pri izvedbenem primeru je sojemalo 12 izvedeno kot poseben sestavni del, ki je po načinu čelnega ozobja oblikosklepno povezan z ročnim zavornim vzvodom 11.As is best apparent from FIG. 2, the hinge 9 is pivoted pivotally into two housing side portions 1a which, in the embodiment, extend the hose 1 downwards. In the space between these housing side members la, by means of bearing bushing 8c, pivotably lever a pivoting lever 8 with its upper lever arm 8a extending into the axial tube 8. Outside one of the housing side parts la, there is a hinge 9 further to support the manual brake lever 11. Between the two the latter, in turn, is pivotally mounted on hinge 9, which is non-hingedly connected to the handbrake lever 11 on the one hand and on the other in the area between hinge 9 and the bearing face of the diversion lever 8 for the drawbar 4 to the diversion lever 8. in the case, the handle 12 is designed as a separate component, which, in the manner of the frontal gear, is closely connected to the handbrake lever 11.
Ker na tečaju 9 nista uležiščena le preusmerni vzvod 8 in ročni zavorni vzvod 11, temveč tudi z ročnim zavornim vzvodom 11 nezasučno povezano in na preusmerni vzvod 8 delujoče sojemalo 12, odmik od tal ni omejen. Razen tega imamo opraviti z zaščiteno namestitvijo za zavoro priklopnega vozila 2 pomembnih delov znotraj po načinu ohišja izvedenega podaljšanja ojesne cevi 1 s pomočjo obeh ohišnih stranskih delov la.Since the hinge 9 is not only mounted on the diversion lever 8 and the handbrake lever 11, but also with the handbrake lever 11 non-pivotally connected and on the diverting lever 8, the actuator 12 operates, the ground clearance is not limited. In addition, there are two important parts for the trailer to be secured for the trailer brake within the axle tube extension 1 by means of both housing side members 1a.
Skici sl. 1 in 2 nadalje kažeta, da pod ležiščno pušo 8c na ročnem zavornem vzvodu 11 uprijema t.i. utržna vrv 14, ki je s svojim prednjim koncem povezana z vlečnim vozilom in pri nenačrtovani popustitvi sklopke med vlečnim vozilom in priklopnim vozilom 2 samodejno povzroči aktiviranje zavore priklopnega vozila 2.Sketches fig. 1 and 2 further show that under the bearing bushing 8c on the handbrake lever 11, it resists the so-called. the rope 14, which is connected with its front end to the towing vehicle and automatically causes the trailer brake 2 to activate when the clutch is loosened loosely between the towing vehicle and the trailer 2.
