| 1. | This first claim for this'TwoWheeisForward'invention, typically for steering system suitable to the vehicles (scooter, little motorcycle, motorcycle, bicycle) = (becoming with 3 wheels) is realized, whether via 2 parallel arms with 2 parallel singular wheels (instead of one), or similarly, with 2 parallel'Y. forks' and their 2 singular wheels ; both wheels have the equidistance from the middle of the steering stem that, at its base, via the 2 extremities of a rigid shaft, brings the 2 top ends of the two arms, or the two stems of the 2'Y. forks'. |
| 2. | Each arm brings its wheel via a speclal elastic indipendent sospension. Both arms, via the steering stem, allow to steer and incline and each wheel adhere, consistently and proportionally according to the balanced weight, at the ground, . |
| 3. | This second claim for this'TwoWheeisForward'invention, whose the preceding claims have been done, improve the interesting vehicles to stand up without using the side stand or the center stand, either in parking or in stopping at the red traffic light ; we automatically also obtain, a major stability in marching,'due to the 3 wheels'. For these reasons is convenient to suit the vehicles with more robust or heavier structure in order to apply electric tractionfheaur. baXeriesXand new hard. cove new reinforced little sidedoors, new safety. belts. and so on.., so the drivers and/or passengers will have best protections. |
| 4. | This third claim for this'TwoWheelsForward'invention, whose the preceding claims have been done, typically for the vehicles can be doted with the reverse. geared and in 2 front. wheels the hand parking rake . |
| 5. | This fourth claim forthis'TwoWheelsForward invention, whose the preceding claims have been done, typically for thevehiclesthe steering stem can be doted with hand. bar or with steednc tialfsteerinq. wheef or similar ; or to have the steering stem directly on each single arm or indirectly, via other mechanisms or via 'steering. serve'. |
| 6. | This fifth claim for this'TwoWheelsForward'invention, whose the preceding claims have been done, typically for the vehicles can be doted of specia elastic sospensions made with bow. spring or similar. |
| 7. | This sixth claim for this'TwoWheeIsForward'invention, whose the preceding claims have been done, typically for the vehicles doted of the rigid shaft joining the two arms or the two'Y. forks'that support both wheels and so on.., made with bow. springor similar. |
| 8. | This seventh claim for this'TwoWheelsForward'invention, whose the preceding claims have been done, typically for the vehicles having the two arms either inside of 2 vertical planes of wheels (wheels outside), or outside of 2 vertical planes of wheels (wheels inside). |
| 9. | This eighth claim for this'TwoWheeIsForward'invention, whose the preceding claims have been done, typically for the vehicles can be similar to the version showed in'fig. 6'. Beginning from the bottom, namely, the 2 parallel wheels, with their special singular elastic sospensions E'+'H'+'Gi'+'A'are sustained on top by 2 orizzontal parallel frames'C' linked to 2 vertical parallel telescopic. t1st before/2nd behind). elastic. .. sospensions'B', where on, the steering stem'X'is suitable (fixed'F'), to steer.. to incline.. and so on.. like the actual system whith single front wheel. Let's specify better: The second lower frame supports two other little 2 arms 'G', where a crossing. orizzontal shaft'H'hinges in the middle ; those 2 arms support (like 2 neutral rods) the 2 opposite tired rods'E'of the 2 parallel wheels and at its estremities, bring the specia elastic sospensions'A', The first upper frame brings (linked to the lower) the two vertical parallel telescopic. (16t before/2nd bL. hind). elastic. ssospensions'B', where on the steering stem'X'is suitable (fixed'F') ; so the entire system can curve and incline. Each wheel is elastically indipendent because it has one (or two) mechanical sospension with special elastic support. (Dual sospensions mean mechanical simmetry"'balanced"'and/or less"vibration"with driving). |
| 10. | This nineth claim for this'TwoWheeisForward'invention, whose the preceding claims have been done, typically for the vehicles can be similar to the version showed in'fig. 7'. Beginning from the bottom, namely, the 2 parallel wheels, with their special singular elastic sospensions 'E'+'H'+'G'+'A'are sustained by a cross. skeleton'D2'linked to 2 vertical parallel telescopic. (ist before/2nd behind). elastic. supports'B'that are linking upper to an orizzontal frame'1) 1'where on the steering stem'X' is suitable (fixed'F'); so the entire system can curve and incline. Each wheel is elastically indipendent because has one (or two) sospension with sPecial elastic support (Dual sospensions mean mechanical simmetry"'balanced"'and/or less"vibration"with driving) W... . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . |
This invention can have also new versions likewise showed in'Fig. 6 and fig. 7': namely, the 2 front wheels, with their special singular elastic suspensions'A', are on top sustained, eithertr. sy by 2 orizontal parallel frames'C'joined to 2 parallel vertical telescopic (1 st betbre/Snd behind) elastic-suspensions'B', where on, the steering stem'X'is suitable (fixed'F'), {'tig-7't Or ('fig. 7') similarly, by an orizzontal parallel frame'D1'up and a parallel cross- .-skeleton'D2'down, built to steer and incline exactly like actual system.
This vehiclehas 3 points of contact to the ground, (instead of 2, obviously, like the actual system), and similarly it, normally, allows it to curve with the regular inclination, but addin the function of'sfandna up'when it is in temporal stoped or arked ; it usually, mantains a spectacular agility and stability on the variable soil route ; therefore, for these reasons, this application is suitable on each kind of actual (vehicße 17at2ß. 4) scooter, little motorcycle, motorcycle and bicycle and therefore allows to improve the safety on the normal roads (on the variable soil routes) due to the improved stability to the questioned vehicle and this is especially valid during the situations of: 'A)-variable weather ( ?) ; covering roads with slimy sand (stewing) or routes where inside are tram-railways becoming slippy, and so on.. covering straight line or uniformt or twisted or variable way, either"speeding"or"braking"or"accelerating".
'C)-during brief halts at the red traffic light, it will be not more usefull to put feet on the ground, viceversa could be dangerous.
'D)-in parking, the side and I or center stand, are now cumbersome.
This'Two FrontWheels'invention integrally transforms the actual steering system with 1 singular wheel, in a system with 2 wheels maintaining the typical agility of the vehicle during every kind of drivening position, whether vertical or inclined, improving the stability and the adhesion (3 points of contact), simplifing also parking, namely, without the side or center cumbersome stand, (unusefuti).
This application will seriously reduce the quantity of the accidents of the scooters, little motorcycle,.. cycles.. and, only for that, it is convenient to suite on every vehicles ; also to the taxi-motorcycle that must be safety more than others having also clients I passengers ; it is suitable also to the patrol-motorcycle that, in case of runnig after, would be operativly more playing it safe (less stewed) This application further allows to support an eventual'hard coverage' (fig. sa) with reinforced little'side-afoors', because, jointly to the 'safety belt', would produce a further protection (a ! so without the helmet) 'NON PLUS ULTRA' (Latin) This original invention, having the 2 frontwheels steering system, inclinable, elastically indipendent, determines a complete reliable reform of the concept of these vehicle (in the styling and driving).
Infact, whether marching or stopping it always offers major safeties and stabilities. It allows to bring heaviest structures (semptifyind also the omologation procedure for'heavy batteries'for eventual electric traction application, for'hard coveraae'for'reinforced litfle sEdedoorstoKsafetv belts'and so on...). Moreover can be doted also of 'reverse qeared'and of'hard brake'on the 2 front wheels, useful in parking This application, for vehicles with 3 wheels, will create the new commercial'3 wheels-motorcycle-segment'that will insert between the actual'2 wheels motorcycle-segment'and'4 wheels-car-segment'.
Next, the trafic produced by this'new 3 wheels-mtrcy-segm.', will most insert in the cities and will contribute to reduce, corrispondently, the '2 wheels-mtrcy-segm.'traffic, but most, the'4 wheels-car-segm.'traffic.
This'new 3 wheels-mtrcy-segm.'will most certainly produce new developments with new knowhow, new laboratory, new plants and new employment.
