Definitions
- TITLE COMPLETE FULL TRANSMISSION SYSTEM FOR BIKES WITH ADAPTATION TO MOTORCYCLES.
- the invention presented here relates to a two-wheel drive transmission assembly for bicycles and motorcycles.
- bikes are equipped with a crankset with one or more chainrings, a chain, a rear drive wheel with freewheel with toothed gears of different sizes.
- the gears are obtained, via derailleurs, by positioning the chain on the various chainrings and toothed sprockets.
- the bicycle transmission described below does not contain a chainwheel, chain, rear chain sprockets or derailleur, but includes a 16-speed gearbox housed in the crankset hub, 2 drive shafts, one for the rear wheel and one for the front wheel, the movements of which are transmitted to the wheels by angle gears and freewheel for the rear wheel, and idler gears with "imitation differential" and freewheel for the front wheel.
- bottom frame rails are found very high, which limits any contact of the frame with the environment. It is the ideal shape for mountain bikes. - No visible mechanical parts, except, of course, the pedals, at the bottom of the bottom bracket. Therefore, no risk of deterioration due to impacts with stones or rocks.
- the all-wheel drive mountain bike (MTB) will be the only one that allows you to put all your weight on the front wheel (for example, in a dancer) to climb difficult passages without the risk of loss of grip.
- the gearbox is located in the hub (0) of the crankset. This hub must therefore have a sufficient diameter (about 11 cm) to contain all the gears
- Figure 1 and Figure 2 (the box and a section).
- the crankshaft carries, in an integral manner, four primary toothed pinions (1 - 2 - 3 - 4) whose diameters are respectively (2.4 cm - 3.8 cm - 5.3 cm - 6 cm).
- the bevel pinion (7) which drives the two output shafts (8) is integral with the pinions (A, B, C and D) whose diameters are respectively (6cm- 5cm- 4cm- 3cm). This assembly, mounted on balls, turns freely on the bottom bracket axle.
- gear sets A, B, C or D is selected by pressing the corresponding pin (only one at a time, the three other toothed rings must continue to rotate freely under penalty of blocking the box.)
- the final gearbox report will be a combination of the primary and secondary reports.
- the speed is controlled by rotating a shaft (9) on which are fixed cams (10) which press on the pins.
- the correct positioning of the cams makes it possible to obtain speed control in order, even with the return of the speed number selected on the handlebars.
- the case containing the gearbox can be perfectly sealed, it is possible to introduce a fluid oil base to improve its operation.
- the rear drive shaft is located inside the right frame tube. On the wheel side, it is fitted with a bevel gear 4 cm in diameter and rotates twice as fast as the wheel.
- the bevel gear wheel is 8 cm in diameter and is mounted on a freewheel as for conventional bicycle sprockets.
- Figure 3 (the bike, with a classic frame shape, seen from the right side).
- the front drive shaft (8) is located at
- Figure 4 (the bike, with a suitable all-terrain frame, seen from the right side).
- the transmission shaft at the outlet of the box (8 ') drives, via a relay box (0'), the two shafts (8) located inside the bottom tubes of the frame, which themselves same, are perpendicular to the tube supporting the saddle and to the pivot axis of the fork.
- Figure 5 (the fork seen from the front).
- front transmission (8) rotates clockwise.
- the pinion (11) also.
- the gears (12) are driven and actuate the shafts (14) by
- the shafts (14), integral with the bevel gears (15) drive the toothed wheels (16) and therefore the gears (17) which, in turn, rotate in the same direction, which has the effect of driving the gables (18) relative to the axis of the wheel and therefore the wheel itself at the same speed as the pinions (16). Or more precisely, at the average speed of the two toothed wheels (16), their speed being able to vary during changes of angle of the handlebar.
- FIGURE 6 (the motorcycle fork seen from the front).
- the drive shaft to the front wheel comes from the motorcycle gearbox.
- a differential between the front and rear drive shafts is essential when exiting the gearbox.
- the shaft for the rear wheel is mounted as is already common for many motorcycles that do not have a chain.
- the drive shaft for the front wheel drives a pinion (11) in contact with pinions (12) which rotate freely around the pivot axis of the fork (12 ').
- Figure 7 (the front wheel seen from the front).
- the brake discs (21) are mounted without problem on the wheel, as at present.
- the different sealed ball bearings and the O-rings (22) make it possible to have completely sealed casings (23) in which it is possible to put oil.
- This patent concerns the transmission to the front wheel of a driving force for a motorcycle.
- It includes a motor shaft fitted with a universal joint, idler gears and a sliding shaft mounted in the telescopic fork.
- the patent which is the subject of the present filing does not specifically include a gimbal. the articulation of the fork, which also allows the fork to pivot at an angle of more than 90 °. (no gimbal allows it).
- my mechanism can only work if it has two shafts (one in each tube of the fork) to bring the driving force to the front wheel.
- a single shaft assembly cannot therefore follow the same operating principle.
- This patent concerns a gearbox with gears still in gear.
- gear selection is done by a shaft which, by turning, pushes a lever, and only one, which makes the corresponding primary pinion integral with the primary shaft which carries it.
- the selection was made by a tree which, by turning, pushes rods, two by selected speed, which, on the contrary, block the rotation of toothed crowns.
- this patent relates to a 13-speed gearbox for pedal cycles.
- the Hartmann system is designed to be installed in the bottom bracket which is also the hub of the front wheel of a cycle. (recumbent trike or bike. as shown in the abstract). My system, mounted in the bottom bracket, is, on the contrary, particularly suitable for classic bikes.
- the Hartmann gear selection system is a dog clutch system, controlled by cables, (cables that make an angle of 90 ° set with a box, ie wonder how we can change them when they break, which will be inevitable). This interconnection secures the selected pinion with the shaft on which it is mounted.
- My selection system blocks a toothed crown, which causes the drive of the corresponding shaft, very different mechanism on the principle used, compared to
- the selection system is always a dog clutch system, controlled by cables. (with an angle of 90 °!). My system does not use interconnection.
- the 16 speeds are obtained by combinations of 3 stages of ratios, (2 times 5 speeds plus a direct catch).
- the 16 speeds of my patent are obtained by combinations of 2 stages, (4 times 4 speeds without direct drive).
- the pieces always rotate in the same direction, or do not rotate, when they are blocked by the rods. This is not the case with the Hartmann mechanism, where certain parts turn, either in one direction or the other, which forces it to mount three complex systems of ratchet wheels ( Figures 4 and 6 of its plans) .
