ROAD VEHICLE FOR TRANSPORTING PEOPLE AND GOODS, WITH VARIABLE WEIGHTS DISPLACEMENT

Abstract: In the traditional vehicles, the driver's position is fixed on one of the 2 sides; this involves an unbalancing of the weights in the order of 6/7 %. In a small vehicle a fixed position of the driver could cause weight's unbalance above 25 %. This fact can decrease the vehicle stability on the bends. This industrial invention allows the side shifting of the driver's position in the vehicle, thus always allowing the establishment of the weights balance. Therefore it provides the best road holding to the vehicle. Moreover, the system facilitates the use of such vehicle by handicapped people.

Description: 1 D E S C R I P T I O N Title: "ROAD VEHICLE FOR TRANSPORTING PEOPLE AND GOODS, WITH WARIABLE WEIGHTS DISPLACEMENT" In order to better explain the essence of this Invention, I make reference to two precedent PCT on the same vehicle, whose drawings are reported on the attachement 2/2. FIG. 8), 9) & 10) refer to PCT/ I T 98/00359 filed 11.12.98; FIG. 11), 12), 13) & 14) refer to PCT/ I T 99/00006 filed 19-1.99. B A C K G R O U N D A R T Usually, in the traditional vehicles, the steering wheel has a fixed I oca tion on one side of the vehicle. -Therefore, also the driver's position is fixed on the left side or on the right side (England). -So, when the driver is alone, a weights unbalance originates in the vehicle. The vehicles manufacturers partially obviate to this unbalance, by pl cing , on the opposite side, some heavy component, such as: the battery, the reservoir, the differential, pumps, alternators, ect. -It happens that, when the passenger is much more heavy than the driver, the weight unba I ance i s emphas i zed. However, in a medium-size traditional vehicle that weights about 1.300 Kgs the side position of the driver induces an unbalance of ab. 6/7 %, tha is considerable only in extreme driving conditions. But, i n a sma I I veh i c I e that we i ghs about 300 Kgs . , if the dr i ver i s alone, he can induce an unbalance above 25%. -If in these conditions, the vehicle turns right with a sharp angle and a considerable speed, the i ns ide whee I s cou Id r i se. D I S C L O S U R E OF I N V E N T I O N The innovations that are the object of this Industrial Invention, have the scope of eliminating the weights unbalance in a small vehicle, through the poss i b i I i ty of sh i ft i ng the steer i ng whec I and the dr i vcr's position, in order to reach a perfect balance, considering also the weights of passengers and goods. For example, the driver can seat in the center, if he is alone; scat no mally on the left, if he is accompanied, and, in any case, situate his position in the right place to balance the actual weiths of passengers and I uggage . -For the r i ght-hand-dr i ve ve i c I es, everyth i ng is reverse . The above i s obta i ncd by mov i ng the support of the steer i ng whee I , in order to place it right in front of the d iver, wherever he could choose to sit, shifting sideway in the vehicle. This is possible because, j n a small vehicle where, in any case, the distance of the pedals from the seat must be anatomical, such distance is relatively long; therefore it allows that the lateral moves of the driver's position, induce a minimum displacement of the steering wheel as regards the pedals, that could be mesured in about 10° (degrees). This limited displacement, that allows the balancing of weights, is pra£ tically irrelevant and more contained than in many vehicles ci culating to day. -This displacement is felt even less, when the ve icle has a continuously variable transmission that, reducing pedals only to break and accelerator, allows to drive with one foot only. Although unnecessary, it could be adopted a mechanism that turns pedals i n correspondence w ith the moves of the steer i ng set-up. THE POSSIBILITY OF LATERAL SHIFTING OF THE DRIVER, THAT IS ACHIEVED THROUGH A SUITABLE CHANGE OF THE ANGLES OF THE STEERING WHEEL PLANE & SUPPORT IS THE PRINCIPAL ASPECT OF THIS INDUSTRIAL INVENTION, INDEPENDENTLY FROM THE MECHANISM ADOPTED. - The mechanisms shown below as examples, are anyhow part of the Invention. The move of the steering wheel can be obtained in different ways, amongst them: 3 1) If the steering wheel column is set laterally as in FIG.l) &4) of the attached Drawings table, - important part of this Invention - its rota tion for a few angle degrees, can achieve the centering of the steering wheel in front of the driver, in any point he may seat, comprised between the center and the lateral end of the vehicle, (left for Italy). FIG. 1) shows, with a projection from above, a lateral steering column pi oting on (4) that, at the end of an horizontal arm (2), bears the steer i ng whee I . When the driver seats centrally on the bench seat, the steering column, pivoting on (4) moves the horizontal arm and the steering wheel, rispec- tively to the positions (2a) & (3a), putting the steering wheel in a co rect pos it ion in front of the dr iver . FIG.4) shows the same steering system as in FIG.l), but seen from the front of the vehicle. - N° (4) & (5) of FIG.4) show 2 possible positions that the driver can take. -The steering column (2) of FIG. 4) can turn clock-wise and viceversa, and can be locked/unlocked in (1) in order to correctly fix the steering wheel in front of the driver. This structure allows the rotation of the steering wheel and column, by an angle wider than 90° (ninety degrees); therefore, it is possible to totally free, the access to the bench-seat, by s ifting to the left side the whole steering set-up, -Also a handicapped man can then enter (backwards) the vehicle, while sitting on his wheel-chair, without help. The rotation and loc ing of the lateral stee ing column, can take place in several ways. -We desc ibe herebelow some of them: ° FIG.2) shows 2 discs (3) & (5) separated by a suitable material (cork or else), - Theese discs are pressed by eccentric members (6), screws or else, suitable to lock/unlock the rotation of the steering column. FIG.2° shows the discs separately, for better understanding. ° Or, more simply, adopting, as in FIG.3) a sleeve (1) clutched around the steering column (2) by means of flaps (3) tightened by screws (4), eccentrics, or else. 2) FIG.5) shows an alternative mechanism that, through the adjustment of: 4 a) the steering column support 5), turning as per (14); b) the rotation of the steering column (2) with the steering wheel (1), vertically in respect of the axel (13); c) the ho izontal angle of the stee ing column (2), with the stee ing whee I ( 1 ) ; a I lows to achieve the best possible position of the steering wheel in front of the d iver, in any place he would scat, on the left half of bhe bench-sea . The steering column (2) is connected to the steering axel (13), by means of an universal joint (3) / that also allows the movements described at points b) and c) above. The knob (9) turns an axel that screws in the nut (11), thus ightening 2 crown wheels (10) positioned at both ends of the perforated bar (15). This allows to fix the two gidcs (6) at an angle that give the best vertical position to the steering column/wheel assembly, as regards the dr i ve . The bearing (4) can be fixed in the wanted position by the knob (12) that, scre ing in the inside of the bea ing (4), bites the 2 gides (6), holding the ball bearing in the wanted position. -The ball joint (8) allows the stee ing wheel (l) to achieve the correct position. The bands (7) are conceived to reinforce the conjunction of the whole mechanism to the stee ing support (5). This kind of mechanism, as shown in FIG.5), allows, besides the possibj ^ I ity of giving to the steering wheel an infinite number of micrometric regulations, also the possibility of freeing easily and completely, the access to the bench seat, by rotating the steering column support (5) by more than 90° (degrees). This is useful also for letting in handicapped People sitting on thei whee I -chair, of course,after having removed part of the standard bench-seat. 3) Adopting a more traditional steering column FIG.6), integral part of this Invention, it can be actuated the side shifting of the steering wheel and, consequently, of the driver, also through a floor cardan joint (3). 5 Also through this mechanism, it is possible to achieve the weight bal nce; but it can be not equal ly functional for an use by handicapped People. In FIG.6), the steering wheel (1) and relevant column (2) are facing the driver who scats on the left side, and transmits rotation to an axel situated at the floor level, through a cardan joint (3), or other type of flexible joint. -The steering column (2) is connected to the column (5) by a sliding ball joint. -When the d iver, in order to establish the weights balance, has to shift lateral ly towards the center of the vehicle, the steering wheel, sliding along the column (5), as in FIG.6), to the positions (la), (2a) & (4a), will place itself in the ideal posi- 11 on for the dr i ver . Also in this case, by fixing the column (5) with one of the mechanism m dicated in FIG. 2) & 3), and by fixing the ball-joint (4) along column (5) it is possible to choose practically endless angles and inclinations su_i_ table to the driver and to the weghts balance. In the inferior part, the cardan joint (3) ends ith ia sleeve (7) that has on top a I rger meta I r i ng. -Sa i d s Ieevc i s engaged upon a vert i ca I axel (8) suitably shaped, from which the rotation of the stee ing wheel is transmitted, through traditional mechanisms, to the steered wheels. A sliding yoke (9) is inserted over the metal ring ( 11) of the sleeve (7), preventing the cardan joint (3) to sleep off from the axel (8). The floor (10), through the hole (11), will make possible to slip off the cardan joint (3) from the axel (8), when the yoke (9) is moved back, as per drawings. -FIG. 7) shows an enlargement of FIG.6) including the cai— dan joint and its way of angaging/disengagi ng from the lower axel (8). The dis insert ion of the column (2) from axel (8), together with the rota tion of more than 90° (degrees) of the column (5), makes it possible to totally clear the access from the front, to the inside of the vehicle, with the exception of the two diving pedals. This can be done, because the column (5), the steering wheel (1) and the column (2), through a rotation as per (6) can be set aside on the left (for the I eft-hand-dr i ve veh i c Ies) in such a pos it i on to occupy spaces not required for entering.
