Abstract

The subject of invention is a movable driving bicycle drum mounted by spokes to the rear wheel of a bicycle, especially a movable centre mechanism (movable element, spring) which enables the mobility of the hub by means of a shaft and bearings. A technical problem the invention tends to solve is such a structure of a driving hub, which would enable rotability or mobility of the central part of the hub around its shaft independently of the rotability of the exterior driven part of the hub which is mounted by spokes to the wheel rim, and would eliminate in this manner the play of the bicycle's cranks, which would affect a higher speed of the bicycle consequently. The technical problem according to the invention is solved by that the exterior driven part of the hub is linked to the interior driving part, to which a bearing hub of a sprocket assembly is fixed by screws. The driven and the driving part of the hub are intersupported by a needle bearing which allows a torsion spring to make a certain path independently of the exterior driven part of the hub. In the centre of the hub, the torsion spring is attached both with a lever, which is anchored under a suitable angle to the shaft, into a groove of the interior driving part of the hub, and with another lever which is backed by a threaded pin screwed into the exterior driven part of the hub. Because the exterior driven and interior driving part of the hub are interlinked and bearing-supported as previously described, the play of the bicycle's cranks is eliminated, as the straining or releasing of the spring enable the motion of the centre mechanism (interior part of the hub) independently of the exterior part of the hub.

Description

Predmet izuma je gibljivo gonilno kolesno pesto, ki je s špicami montirano na zadnjem kolesu kolesa, zlasti gibljiv sredinski mehanizem (gibljiv element, vzmet), ki z osjo ter ležaji omogoča gibljivost pesta.The subject of the invention is a movable drive wheel hub, which is mounted with spokes on the rear wheel of the wheel, in particular the movable center mechanism (moving element, spring), which enables the hub to move with the axle and the bearings.

Funkcija do sedaj znanih vrst zadnjih kolesnih pest je predvsem omogočanje vrtljivosti kolesa okoli osi, ki je vpeta skozi center pesta in s tem omogočanje gibanja oziroma premikanja kolesa po določeni poti.The function of the known types of rear wheel hubs so far is primarily to allow the wheel to rotate about an axis that is threaded through the center of the hub, thereby allowing the wheel to move or move along a certain path.

Tehnični problem, ki ga rešuje izum, je takšna konstrukcija gonilnega pesta, ki bo omogočala vrtljivost oz. gibljivost sredinskega dela pesta okrog osi neodvisno od vrtljivosti zunanjega dela pesta, ki je s špicami pritrjen na obroč kolesa, in s tem odpravo mrtvega hoda gonilk kolesa, kar bo posledično vplivalo na višjo hitrost kolesa.The technical problem that is solved by the invention is such a design of the drive hub, which will allow rotation or. movability of the center part of the hub around the axle independently of the rotation of the outer hub, which is fastened with the spokes to the wheel ring, thereby eliminating dead movement of the wheel cranks, which will in turn affect the higher speed of the wheel.

Ostali problemi, ki jih rešuje pričujoči izum so, kako izboljšati izkoristek kolesarja brez uporabe prepovedanih, danes vse bolj zlorabljenih dopingških sredstev za doseganje vedno boljših rezultatov.Other problems solved by the present invention are how to improve cyclist efficiency without the use of illicit, increasingly misused, doping agents to achieve ever better results.

Do sedaj znana rešitev odprave mrtvega hoda gonilk je po patentu EPO148192 (slika 1). Mehanizem za odpravo mrtvega hoda gonilke je sestavljen iz objemke (1), ki je pritijena na zadnji vilici navpično z dvema kovinskima palicama (2 in 3), ki sta sestavni del vilic, točno nad zadnjim kolesom.A known solution to the deadlocking of crankshafts so far is the patent EPO148192 (Figure 1). The deadbolt deadbolt mechanism consists of a clamp (1) that is attached to the rear fork vertically by two metal rods (2 and 3), which are an integral part of the forks, just above the rear wheel.

Dolžina te objemke je nekoliko daljša od vodoravne razdalje ene gonilke (8) do druge (9). Skrajna dela gonilk (8,9) sta povezana z objemko preko dveh elastičnih vrvic (4,7) na obeh straneh kolesa.Ti dve vrvici oziroma elastična kabla pa sta povezana na gonilke (5,10) s spojkama (6) ali kako drugo vrsto konektorjev, ki sta pritrjena na notranji skrajni del vsakega pedala poleg gonilke (8,9).The length of this clamp is slightly longer than the horizontal distance of one crank (8) to the other (9). The ends of the cranks (8,9) are connected to the clamp via two elastic cords (4,7) on either side of the wheel. These two cords or elastic cables are connected to the cranks (5,10) by clamps (6) or otherwise. a series of connectors attached to the inner extremity of each pedal next to the crank (8,9).

Tehnični problem je po izumu rešen s tem, daje zunanji - gnani del pesta s torzijsko vzmetjo povezan z notranji - gonilnim delom, na katerega je z vijaki pritajeno nosilno pesto sklopa zobnikov. Gnani in gonilni del pesta sta med seboj uležajena z igličnim ležajem, ki dopušča, da torzijska vzmet opravi določen hod neodvisno od zunanjega - gnanega dela pesta. Torzijska vzmet je vpeta v centru pesta z ročico, ki je zasidrana pod primernim kotom na os v utor notranjega - gonilnega dela pesta ter z drugo ročico, ki je prislonjena na zatični vijak, ki je privit v zunanji - gnani del pesta. Mrtvi hod gonilk kolesa je odpravljen, saj vzmet s tem, ko se napenja oziroma sprošča, dopušča gibanje notranjega dela pesta neodvisno od zunanjega dela pesta.The technical problem according to the invention is solved by the fact that the outer drive part of the hub with a torsion spring is connected to the inner drive part, to which the bearing hub of the gear assembly is fastened with screws. The driven and driving parts of the hub are interconnected by a needle bearing, which allows the torsion spring to perform a certain stroke independently of the outer - driven part of the hub. The torsion spring is clamped in the center of the hub with a lever anchored at a suitable angle to the axis in the groove of the inner - driving part of the hub, and with the other lever resting on a pin screw that is screwed into the outer - driven part of the hub. The dead wheel travel is eliminated because the spring, by tilting or releasing, allows movement of the inner part of the hub independently of the outer part of the hub.

Ostali problemi so po izumu rešeni s tem, da torzijska vzmet v sredinskem mehanizmu omogoča odpravo mrtvega hoda gonilk kolesa in s tem boljši izkoristek ter manj porabljene vložene energije kolesaija, kar se posledično pozna na hitrosti kolesa.Other problems according to the invention are solved by the fact that the torsion spring in the central mechanism allows the deadlift of the wheel cranks to be eliminated, and thus the better utilization and less spent energy of the wheel, which is consequently known at the speed of the wheel.

Podrobneje so značilnosti izuma pojasnjene v nadaljevanju z opisom izvedbenega primera (prototipa) in s pomočjo risb, ki prikazujejo:The features of the invention are explained in more detail below by a description of an embodiment (prototype) and by means of drawings showing:

Zunanji - gnani del pesta (1) je s torzijsko vzmetjo (7) povezan z notranjim - gonilnim delom pesta (3), nanj pa je s pomočjo vijakov pritrjeno nosilno pesto (2) sklopa zobnikov. Gnani in gonilni del pesta sta med seboj uležajena z igličnim ležajem (6), ki dopušča oziroma omogoča, da torzijska vzmet (7) opravi določen hod neodvisno od zunanjega - gnanega dela pesta (1). Torzijska vzmet (7) je vpeta v centru pesta z ročico, kije zasidrana pod primernim kotom glede na os (5) v utor notranjega - gonilnega dela pesta ter z drugo ročico (11), ki je prislonjena na zatični vijak (10), ki je privit v zunanji - gnani del pesta (1). Mrtvi hod gonilk kolesa je odpravljen, saj torzijska vzmet (7) s tem, ko se napenja oziroma sprošča, omogoča gibanje notranjega - gonilnega dela pesta (3) preko igličnega ležaja (6) neodvisno od zunanjega - gnanega dela pesta (1).The outer - driven part of the hub (1) is connected to the inner - driving part of the hub (3) by means of a torsion spring (7), and to it is secured by means of screws the supporting hub (2) of the gear assembly. The driven and driving parts of the hub are interconnected by a needle bearing (6) which permits or allows the torsion spring (7) to perform a certain stroke independently of the outer driven part of the hub (1). The torsion spring (7) is clamped in the center of the hub with a lever anchored at a suitable angle with respect to the axis (5) into the groove of the inner drive part of the hub, and with the other lever (11) resting on the pin screw (10), which it is screwed into the outer - driven part of the hub (1). The dead wheel travel is eliminated, since the torsion spring (7), by tensioning or releasing, enables the movement of the inner - driving part of the hub (3) through the needle bearing (6) independently of the outer - driven part of the hub (1).

Torzijska vzmet (7) se pri premiku sklopa zobnikov preko nosilnega pesta (2) in notranjega gonilnega dela pesta (3) napne ter tako pritiska preko zatičnega vijaka (10) na zunanji - gnani (1) in preko ročice (8) na notranji - gonilni (3) del pesta v obratni smeri kot se vrti sklop zobnikov. Vzmet (7) je med potiskanjem gonilk kolesa neprestano napeta vse do pozicije mrtvega hoda gonilk.The torsion spring (7) is tensioned when the gear assembly is moved through the support hub (2) and the inner drive part of the hub (3), so that it is pressed through the pin screw (10) on the outer drive (1) and through the lever (8) on the inner one. the drive (3) part of the hub in the opposite direction as the gear assembly rotates. The spring (7) is continuously tensioned while pushing the wheel sprocket until it is deadlocked.

V začetni točki mrtvega hoda gonilk, kolesar s potisno silo ustvaga oporo na ročico (8), ki je zasidrana v utoru (9) notranjega - gonilnega dela pesta. V tej točki se torzijska vzmet (7) prične sproščati preko zatičnega vijaka (10), ki je privit v zunanjem - gnanem (1) delu pesta in tako povzroča navor kolesa, ki dovoljuje razbremenjen premik mrtvega hoda gonilk.At the starting point of the dead center of the gearboxes, the cyclist pushes the support to the lever (8), which is anchored in the groove (9) of the inner - driving part of the hub. At this point, the torsion spring (7) starts to be released through the locking screw (10), which is screwed into the outer (1) part of the hub, thus causing the wheel torque to allow for a relaxed movement of the dead gear.

V mrtvem hodu gonilk omogoča gonilno silo akumulirana energija v torzijski vzmeti, ki požene gnani - zunanji del pesta za določen kot, ki je približno enak premiku mrtvega hoda gonilk.In the dead-end of the gearboxes, the driving force is the accumulated energy in the torsion spring which drives the driven - the outer part of the hub by a certain angle approximately equal to the displacement of the dead-gear of the gearboxes.
