Description
RAZBREMENILNO DVIGALO ZA DVIG VOZILVEHICLE RELIEF LIFT
Področje tehnikeThe field of technology
Izum sodi v področje naprav za dviganje, bolj natančno v področje okvirjev in mehanizmov za dvigovanje vozil in drugih težjih predmetov ali oseb. Izum se nanaša na razbremenilno dvigalo za dvig vozil.The invention belongs to the field of lifting devices, more precisely to the field of frames and mechanisms for lifting vehicles and other heavy objects or persons. The invention relates to a relief lift for lifting vehicles.
Ozadje izuma in tehnični problemBackground of the Invention and Technical Problem
Vozila, še posebno težka vozila, se med dolgotrajnim parkiranjem zaradi svoje teže spustijo. Pnevmatike se zato sploščijo, kar se ob pričetku vožnje občuti, lahko pa predstavlja tudi nevarnost, saj pnevmatike niso v optimalnem stanju. Starejše kot so pnevmatike, bolj se te deformacije poznajo in težje med vožnjo dosežejo običajno obliko. Tehnični problem je konstrukcijska zasnova dvižne ploščadi za vozilo, s katero bo možno le-tega dvigniti, da ne bo med dolgotrajnim parkiranjem vozila prišlo do deformacije pnevmatik.Vehicles, especially heavy vehicles, fall due to their weight during long-term parking. The tires therefore become flat, which is felt at the start of the ride, but can also represent a danger, as the tires are not in optimal condition. The older the tires, the more these deformations are known and the more difficult it is for them to reach their normal shape during driving. The technical problem is the structural design of the lifting platform for the vehicle, with which it will be possible to raise it, so that the tires will not be deformed during long-term parking of the vehicle.
Stanje tehnikeState of the art
Znane so rešitve dvigal za avtomobile, ki so namenjena za parkirne garaže, kot je na primer opisano v patentu FR2461078, vendar pa se od pričujoče rešitve razlikujejo po konstrukciji. Tudi dvigala za popravilo vozil so zasnovana drugače. Tako na primer dokument DE3529069 opisuje ločene paralelne sani, na katere lahko zapelje vozilo. Slednjega se lahko dvigne s pomočjo škarjastega mehanizma, kije nameščen v saneh. Uporabni model opisuje DE 102004009092 podobno rešitev, vendar pa so sani med seboj povezane, v rešitvi predstavljeni v uporabnem modelu DE102010027889 pa so sani povezane v spodnjem delu. Slednji dokument uporablja dvojni škarjasti mehanizem za dvig sani, kar se razlikuje od pričujočega izuma. Patent RS96104 razkriva drugačno rešitev avtomobilske dvigalke. Te rešitve ne omogočajo dviga vozila na način, da bi bila kolesa v zraku, saj vozilo stoji s kolesi na omenjenih saneh.Car lift solutions intended for parking garages are known, as for example described in patent FR2461078, but they differ from the present solution in terms of construction. Vehicle repair lifts are also designed differently. For example, document DE3529069 describes separate parallel sleds on which a vehicle can drive. The latter can be lifted with the help of a scissor mechanism installed in the sled. The utility model DE 102004009092 describes a similar solution, but the sleds are connected to each other, and in the solution presented in the utility model DE 102010027889, the sleds are connected in the lower part. The latter document uses a double scissor mechanism to lift the sled, which differs from the present invention. Patent RS96104 reveals a different solution for a car lift. These solutions do not allow the vehicle to be lifted in such a way that the wheels are in the air, as the vehicle stands with the wheels on the said sled.
Patent DE3943425 opisuje dvigalko za vozilo, ki ima dve tirnici oziroma stezi dvižni s pomočjo dveh križnih konstrukcij medsebojno povezanih v osrednjem vrtišču. Križni konstrukciji sta dvižni s pomočjo hidravličnih cilindrov. Alternativno, ta dokument razkriva dvigalko, katere stezi se dvigneta s pomočjo paralelogramskega mehanizma. Na podlago je sta pritrjeni dve podporni palici, od katerih je ena opreljena s hidravličnim cilindrom za zagotavljanje dviga, druga pa se iztegne avtomatsko zaradi dviga prve. Obe sta povezani s tirnico, kar tvori paralelogram. Le-ta se razlikuje od konstrukcije pričujočega izuma.Patent DE3943425 describes a lift for a vehicle that has two rails or tracks lifted by means of two cross structures connected to each other in a central pivot. The cross structures are lifted with the help of hydraulic cylinders. Alternatively, this document discloses an elevator whose tracks are raised by means of a parallelogram mechanism. Two support rods are attached to the base, one of which is attached to a hydraulic cylinder to provide lift, while the other extends automatically due to the lift of the first. Both are connected by a rail, forming a parallelogram. This differs from the construction of the present invention.
Do sedaj znane rešitve so dvižne sani prilagojene le za dvig nujen za popravilo, ne pa za dolgotrajno parkiranje vozila.The solutions known so far are lifting sleds adapted only for lifting necessary for repairs, but not for long-term parking of the vehicle.
Opis rešitve tehničnega problemaDescription of the solution to the technical problem
Cilj izuma je rešiti pomanjkljivosti zgoraj opisanih znanih rešitev ter posledično razbremenilno dvigalo za dvig vozil, ki daljši čas ne bodo v uporabi.The goal of the invention is to solve the shortcomings of the above-described known solutions and, as a result, a load-relieving lift for lifting vehicles that will not be in use for a long time.
Bistvo razbremenilnega dvigala za dvig vozil po izumu je v tem, da je sestavljen iz: - osnovne konstrukcije vsaj dveh medsebojno vzporednih tirnic, ki sta lahko opcijsko dodatno povezani s poljubnim številom vmesnih povezovalnih elementov;The essence of the relief lift for lifting vehicles according to the invention is that it consists of: - a basic structure of at least two mutually parallel rails, which can optionally be additionally connected with any number of intermediate connecting elements;
- vsaj enega hidravličnega cilindra, ki je na eni strani povezan pogonsko enoto, prednostno s hidravlično črpalko ali agregatom, na drugi strani pa je povezan na dvižni sestav, pri čemer se omenjeni vsaj en hidravlični cilinder lahko kontrolira preko ustreznih ventilov, prednostno preko proporcionalnih hidravličnih ventilov,- at least one hydraulic cylinder, which is connected to the drive unit on one side, preferably with a hydraulic pump or aggregate, and on the other side is connected to the lifting assembly, whereby said at least one hydraulic cylinder can be controlled via appropriate valves, preferably via proportional hydraulic valves,
- dvižnega sestava, ki je sestavljen iz:- lifting assembly, which consists of:
o vsaj dveh prvih prečnih palic, ki povezuje obe vzporedni tirnici, o dveh notranjih tirnic, ki se nahajata med obema tirnicama osnovne konstrukcije, in sta na prve prečne palice povezani s parom povezovalnih ročic zasukljivo vpetih v vpetjih na notranji tirnici in prvih prečnih palicah, tako da se notranji tirnici lahko dvigneta bistveno nad višino osnovne konstrukcije, o vsaj ene druge prečne palice, ki povezuje omenjeni notranji tirnici, in je hkrati povezana na eno izmed prvih prečnih palic z dodatnim parom zasukljivih povezovalnih ročic.o at least two first transverse bars connecting the two parallel rails, o two inner rails located between the two rails of the basic structure, and connected to the first transverse bars by a pair of connecting arms rotatably clamped in the clamps on the inner rail and the first transverse bars, so that the inner rails can be raised significantly above the height of the base structure, by at least one other crossbar connecting the mentioned inner rails, and at the same time is connected to one of the first crossbars with an additional pair of rotatable connecting arms.
Vpetje ročic na prečne palice je poljubno, omogočati mora rotacijo ročic okoli prečnih palic. Prednostno je ročica opremljena z izrezom, v katerega se namesti prečna palica, okoli katere lahko rotira. Vpetje povezovalne ročice na notranjo tirnico je lahko katerokoli, prednostno je izvedeno z vijaki. Zaželeno je, da je vsaka povezovalna ročica v paru, torej, da je na vsaki strani vsake prve prečne palice za povezavo na notranjo tirnico uporabljen dvojni par ročic 8 zaradi boljše stabilnosti in zanesljivosti.The attachment of the arms to the crossbars is arbitrary, it must allow rotation of the arms around the crossbars. Preferably, the handle is provided with a cut-out into which a transverse rod is placed, around which it can rotate. The connecting lever can be attached to the inner rail in any way, it is preferably done with screws. It is desirable that each connecting arm is in a pair, i.e. a double pair of arms 8 is used on each side of each first cross bar for connection to the inner rail for better stability and reliability.
Notranje tirnice so lahko enodelne ali več delne, pri čemer so v primeru slednjega kontakti oziroma vpetja izvedeni na katerikoli primeren način. Pri večdelnih tirnicah so lahko posamezni odseki tudi različnih oblik ali iz različnih materialov, kar je odvisno od tega kateri del vozila podpirajo.Internal rails can be one-part or multi-part, and in the case of the latter, the contacts or fastenings are made in any suitable way. With multi-part rails, individual sections can also be of different shapes or made of different materials, which depends on which part of the vehicle they support.
Hidravlični cilinder je prednostno pritrjen na omenjeno drugo prečno palico, tako da jo lahko ob iztegu bata hidravličnega cilindra dvigne, s tem pa tudi notranje tirnice. Vsi deli dvižnega sestava se morajo premikati sinhrono, zato da pri dvigu ne pride do nagiba vozila. V najvišji višini notranjih tirnic so povezovalne ročice pravokotne na prve prečne palice, medtem ko so v zloženem položaju dvigala vzporedne tirnicam, tako osnovnim, kot tudi notranjim. Z opcijskimi vijaki se lahko nastavi višino povezovalnih ročic, ki se zavihtijo. Položaj notranjih tirnic se lahko ustavi tudi pri katerem drugem kotu povezovalnih ročic na prve prečne palice, kar se določi z ustrezno kontrolo hidravličnega cilindra. Vklop razbremenilnega dvigala po izumu je z vklopom pogona, ki nato poskrbi za kontrolo ventila, ki posledično vpliva na stanje hidravličnega cilindra ter pozicijo dvižnega sestava.The hydraulic cylinder is preferably attached to said second transverse rod, so that when the piston of the hydraulic cylinder is extended, it can be lifted, and thus also the inner rails. All parts of the lifting assembly must move synchronously, so that the vehicle does not tilt during lifting. At the highest height of the inner rails, the connecting arms are perpendicular to the first crossbars, while in the folded position the elevators are parallel to the rails, both base and inner. Optional screws can be used to adjust the height of the swinging link arms. The position of the inner rails can also be stopped at any other angle of the connecting arms to the first transverse bars, which is determined by the appropriate control of the hydraulic cylinder. The unloading lift according to the invention is switched on by switching on the drive, which then controls the valve, which in turn affects the state of the hydraulic cylinder and the position of the lifting assembly.
Pogon razbremenilnega dvigala je prednostno izveden preko hidravlične črpalke ali agregata, lahko pa se izvede tudi z elektromotorjem ali katerim drugim pogonom. Premik notranjih tirnic bi bil lahko namesto s hidravliko izveden tudi s pomočjo aktuatorja in elektromotorja, s pomočjo navojnega vretena ali podobnih strojnih elementov, vendar pa te izvedbe niso tako učinkovite in zanesljive kot hidravlika.The unloading lift is preferably driven via a hydraulic pump or aggregate, but it can also be driven by an electric motor or some other drive. Instead of hydraulics, the movement of the internal rails could also be carried out with the help of an actuator and an electric motor, with the help of a threaded spindle or similar mechanical elements, but these implementations are not as efficient and reliable as hydraulics.
Razbremenilno dvigalo po potrebi lahko nadalje vključuje še druge komponente, kot je na primer opcijska elektronika, ki kontrolira hidravlične ventile hidravličnih cilindrov, in/ali krmilnik s prednostnim zaslonom za izbiro pozicije oziroma višine notranjih tirnic dvigala. Dodatno ima lahko razbremenilno dvigalo še varovalo, prednostno mehansko. Če bi hidravlika začela popuščati, se varovalo aktivira, in prepreči, da bi vozilo padlo.If necessary, the relief lift can further include other components, such as, for example, optional electronics that control the hydraulic valves of the hydraulic cylinders and/or a controller with a priority screen for selecting the position or height of the internal rails of the lift. In addition, the relief lift can have a safety device, preferably a mechanical one. If the hydraulics begin to fail, the safety device is activated and prevents the vehicle from falling.
Dimenzije razbremenilnega dvigala so poljubne in prilagojene velikosti vozila, ki ga je potrebno dvigniti za dalj časa. Dolžina povezovalnih ročic je lahko poljubna, da se lahko prilagodi višina dvignjenih notranjih tirnic v skladu z velikostjo koles vozila. Širina tirnic osnovne konstrukcije in notranjih tirnic je lahko prilagojena vozilu, ki je lahko osebni avtomobil, avtodom, tovorno vozilo ali katerikoli drugo cestno prevozno sredstvo. Glede na dolžino vozila se lahko prilagodi dolžina tirnic, kot tudi število in oblika delov notranje tirnice. Dvigalo podpre vozilo pod vsemi osmi, ki jih ima vozilo, da ne pride do kakšnih premikov ali nestabilnosti.The dimensions of the relief lift are arbitrary and adapted to the size of the vehicle that needs to be lifted for a long time. The length of the connecting arms can be arbitrary, so that the height of the raised inner rails can be adjusted according to the size of the vehicle's wheels. The width of the rails of the basic structure and the internal rails can be adapted to the vehicle, which can be a car, motorhome, truck or any other means of road transport. Depending on the length of the vehicle, the length of the rails can be adjusted, as well as the number and shape of the parts of the inner rail. The lift supports the vehicle under all axles that the vehicle has, so that no movement or instability occurs.
Razbremenilno dvigalo po izumu ima torej vsaj dve poziciji, in sicer:The relief lift according to the invention therefore has at least two positions, namely:
- začetno pozicijo, v kateri so povezovalne ročice vzporedne z notranjimi tirnicami, ki so vzporedne z osnovno konstrukcijo, tako da je dvižni sestav na podlagi, kjer je dvigalo nameščeno, ali pa je kot med ročicami in podlago (osnovnimi tirnicami) oster, prednostno manj kot 45 stopinj, pri čemer je omenjeni lahko tolikšen, da je višina notranjih tirnic še vedno toliko nizka, da lahko vozilo zapelje nad divgalo, ne da bi se notranje tirnice dotikale podvozja ali katerega drugega dela vozila; ter- the initial position in which the connecting arms are parallel to the internal rails, which are parallel to the base structure, so that the lifting assembly is on the base where the lift is installed, or the angle between the arms and the base (base rails) is sharp, preferably less an angle of 45 degrees, whereby the mentioned can be such that the height of the inner rails is still so low that the vehicle can drive over the lift without the inner rails touching the chassis or any other part of the vehicle; and
- dvignjeno pozicijo, v kateri so notranje tirnice dvignjene na osnovno konstrukcijo, kjer je prednostno kot med povezovalnimi ročicami in podlago (osnovnimi tirnicami) večji od 45 stopinj, običajno okoli 90 stopinj, da so notranje tirnice v stiku s podvozjem oziroma osmi vozila, ki je dvignjeno za toliko, da so kolesa v zraku.- a raised position in which the inner rails are raised on the base structure, where preferably the angle between the connecting arms and the base (base rails) is greater than 45 degrees, usually around 90 degrees, so that the inner rails are in contact with the chassis or axles of the vehicle, which is raised so much that the wheels are in the air.
Dvigalo po izumu se uporablja tako, da se vozilo za parkiranje zapelje nad konstrukcijo, nato se z vklopom pogona sproži delovanje ventila ter posledično hidravličnega cilindra, ki dvigne dvižni sestav. Ko pride do končne želene pozicije, se vozilo dvigne toliko, da so kolesa v zraku, s čemer se prepreči deformacije pnevmatik.The lift according to the invention is used in such a way that the parking vehicle is driven over the structure, then by switching on the drive, the operation of the valve and consequently of the hydraulic cylinder, which raises the lifting assembly, is initiated. When the final desired position is reached, the vehicle is raised so much that the wheels are in the air, thus preventing deformation of the tires.
Razbremenilno dvigalo za dvig vozil po izumu bo v nadaljevanju podrobneje opisano s pomočjo izvedbenih primerov in slik, ki prikazujejo:The relief lift for lifting vehicles according to the invention will be described in more detail below with the help of examples and pictures showing:

V obsegu izuma, kot je tukaj opisan in definiran v zahtevkih, so lahko možne tudi druge izvedbe razbremenilnega dvigala, ki so jasne strokovnjaku s področja tehnike, kar pa ne omejuje bistva izuma, kot je opisan tukaj in definiran v zahtevkih. Izvedbeni primer je uporabljen le za ilustracijo možne konstrukcije razbremenilnega dvigala in ni omejujoč.Within the scope of the invention as described herein and defined in the claims, other embodiments of the relief lift may be possible, which are clear to a person skilled in the art, but which does not limit the essence of the invention as described herein and defined in the claims. The embodiment is used only to illustrate the possible construction of the relief lift and is not limiting.
Na sliki 1 je vidna konstrukcija razbremenilnega dvigala za dvig vozil po izvedbenem primeru v dvignjenem položaju brez vidnega vozila, pri čemer je dvigalo sestavljeno iz: - osnovne konstrukcije dveh medsebojno vzporednih tirnic 1, ki sta dodatno povezani z osmimi vmesnimi povezovalnimi elementi 2;Figure 1 shows the construction of a relief lift for lifting vehicles in a raised position without a visible vehicle according to the embodiment, where the lift consists of: - the basic structure of two mutually parallel rails 1, which are additionally connected by eight intermediate connecting elements 2;
dveh hidravličnih cilindrov 3, ki sta na eni strani povezana na hidravlično črpalko 4, na drugi strani pa sta povezana na dvižni sestav, pri čemer se omenjena hidravlična cilindra 3 lahko kontrolirata preko ustreznih ventilov, prednostno preko proporcionalnih hidravličnih ventilov,two hydraulic cylinders 3, which are connected on one side to the hydraulic pump 4, and on the other side are connected to the lifting assembly, whereby the mentioned hydraulic cylinders 3 can be controlled via appropriate valves, preferably via proportional hydraulic valves,
- dvižnega sestava, ki je sestavljen iz:- lifting assembly, which consists of:
o štirih prvih prečnih palic 5, ki povezuje obe vzporedni tirnici 1, o dveh notranjih tirnic 6, ki se nahajata med obema tirnicama 1 osnovne konstrukcije, in sta na prve prečne palice 5 povezani s štirimi dvojnimi pari povezovalnih ročic 8 zasukljivo vpetih v vpetjih na notranji tirnici 6 in prvih prečnih palicah 5, tako da se notranji tirnici 6 lahko dvigneta nad osnovno konstrukcijo, pri čemer imata notranji tirnici 6 vsaj da delih (6a, 6c), na katere nasedejo osi vozila, prečni prerez v obliki ležeče črke H, ter o druge prečne palice 7, ki povezuje omenjeni notranji tirnici 6, in je hkrati povezana na eno izmed prvih prečnih palic 5 z dvojnim parom zasukljivih povezovalnih ročic 8.o four first transverse bars 5, which connects the two parallel rails 1, o two internal rails 6, which are located between the two rails 1 of the basic structure, and are connected to the first transverse bars 5 by four double pairs of connecting arms 8, rotatably clamped in the clamps on the inner rails 6 and the first transverse bars 5, so that the inner rails 6 can rise above the base structure, whereby the inner rails 6 have at least two parts (6a, 6c) on which the vehicle axles rest, a cross-section in the form of a horizontal letter H, and about the second crossbar 7, which connects the mentioned inner rails 6, and is simultaneously connected to one of the first crossbars 5 with a double pair of rotatable connecting arms 8.
Notranji tirnici 6 sta večdelni 6a, 6b, 6c, kot je razvidno iz stranskih risov dvigala prikazanih na slikah 2a in 2b, pri čemer so kontakti oziroma vpetja 9 med deli 6a, 6b, 6c izvedeni na katerikoli primeren način. Prečni prerez delov 6a in 6c, ki sta prilagojena za sprejem osi vozila, je v obliki ležeče črke H, kot je razvidno na slikah 3a in 3b. Ti sliki tudi prikazujeta detajl povezovalnih ročic 8, saj je na vsaki strani vsake prve prečne palice 5 za povezavo na notranjo tirnico 6 predviden dvojni par ročic 8 zaradi boljše stabilnosti in zanesljivosti. Vpetje ročic 8 na tirnico je po izvedbenem primeru izvedeno z vijaki, lahko pa je tudi katerikoli drug primeren element. Povezovalna ročica 8 ima v spodnjem delu primeren izrez, v katerega se lahko namesti prečna palica 5. Ta povezava je lahko izvedena tudi kako drugače, dokler omogoča rotacijo ročic 8 okoli prečne palice 6.The internal rails 6 are multi-part 6a, 6b, 6c, as can be seen from the side views of the elevator shown in Figures 2a and 2b, and the contacts or engagements 9 between the parts 6a, 6b, 6c are made in any suitable way. The cross-section of the parts 6a and 6c, which are adapted to receive the axle of the vehicle, is in the form of a horizontal letter H, as can be seen in Figures 3a and 3b. These figures also show a detail of the connecting arms 8, as a double pair of arms 8 is provided on each side of each first cross bar 5 for connection to the inner rail 6 for better stability and reliability. According to the embodiment, the arms 8 are attached to the rail with screws, but it can also be any other suitable element. The connecting lever 8 has a suitable cut-out in the lower part, in which the transverse rod 5 can be placed. This connection can also be made in a different way, as long as it allows rotation of the levers 8 around the transverse rod 6.
Hidravlični cilinder 3 je pritrjen na omenjeno drugo prečno palico 7, tako da jo lahko ob iztegu bata hidravličnega cilindra 3 dvigne, s tem pa dvigne tudi notranji tirnici 6, kot je razvidno iz slike 3b. V najvišji višini notranjih tirnic, kot je prikazano na slikah 1, 4 in 5, so povezovalne ročice približno pravokotne na prve prečne palice, medtem ko so v zloženem položaju dvigala vzporedne tirnicam, tako osnovnim, kot tudi notranjim ali pa je kot med ročico 8 in podlago oster, prednostno manj kot 45 stopinj. Kot je lahko tolikšen, da je višina notranjih tirnic še vedno toliko nizka, da lahko vozilo zapelje nad divgalo, ne da bi se notranje tirnice 6 dotikale podvozja ali katerega drugega dela vozila. Položaj notranjih tirnic se lahko ustavi tudi pri katerem drugem kotu povezovalnih ročic na prve prečne palice, kot je prikazano na slikah 2 in 3, kar se določi z ustrezno kontrolo hidravličnega cilindra. Vklop razbremenilnega dvigala po izumu je z vklopom pogona, ki nato poskrbi za kontrolo ventila, ki posledično vpliva na stanje hidravličnega cilindra ter pozicijo dvižnega sestava.The hydraulic cylinder 3 is attached to the mentioned second transverse rod 7, so that when the piston of the hydraulic cylinder 3 is extended, it can lift it, thereby also lifting the inner rail 6, as can be seen in figure 3b. At the highest height of the inner rails, as shown in figures 1, 4 and 5, the connecting arms are approximately perpendicular to the first crossbars, while in the folded position the elevators are parallel to the rails, both base and inner, or the angle between the arms is 8 and the base sharp, preferably less than 45 degrees. The angle can be such that the height of the inner rails is still low enough that the vehicle can drive over the lift without the inner rails 6 touching the chassis or any other part of the vehicle. The position of the inner rails can also be stopped at any other angle of the connecting arms to the first cross bars, as shown in Figures 2 and 3, which is determined by the appropriate control of the hydraulic cylinder. The unloading lift according to the invention is switched on by switching on the drive, which then controls the valve, which in turn affects the state of the hydraulic cylinder and the position of the lifting assembly.
Sliki 4 in 5 prikazujeta razbremenilno dvigalo v uporabi z vozilom, pri čemer se vozilo pripelje nad razbremenilno dvigalo, prednostno tako, da je sprednja os nad delom 6c notranje tirnice 6, zadnji osi pa nad delom 6a notranjih tirnic 6. Višina le-teh je še vedno tako nizka, da osi niso v kontaktu z deli 6a in 6c, kolesa vozila pa so na tleh, kot je razvidno iz slike 5b. Nasprotno, je na sliki 5 razvidno, da sta notranji tirnici 6 s pomočjo povezovalnih ročic 8 dvignjeni, da sta dela 6a in 6c notranjih tirnic 6 v kontaktu z osmi vozila, kar povzroči dvig koles, ki je na sliki 5b nakazan s puščico.Figures 4 and 5 show the relief lift in use with a vehicle, whereby the vehicle is driven over the relief lift, preferably with the front axle above the part 6c of the inner rail 6 and the rear axle above the part 6a of the inner rails 6. The height of these is still so low that the axles are not in contact with parts 6a and 6c and the wheels of the vehicle are on the ground as seen in Figure 5b. On the contrary, it can be seen in Figure 5 that the inner rails 6 are raised by means of the connecting arms 8, that the parts 6a and 6c of the inner rails 6 are in contact with the axles of the vehicle, which results in the lifting of the wheels, which is indicated by the arrow in Figure 5b.
