Definitions
- the invention relates to a kit for motorized assistance or light motorization of a vehicle, in particular a light vehicle, such as a bicycle, unicycle, tricycle, four-wheel, rolling chair, with a drive.
- a light vehicle such as a bicycle, unicycle, tricycle, four-wheel, rolling chair, with a drive.
- CONFIRMATION COPY There are, equipped with a motor in the hub of the wheel, similar products in concept BionX. It is the Stromer of Thoemus and the Grace One, which are proposed as integrated e-bikes. The frame is therefore designed especially for the integration of the battery. These two models are not shown in the test series described below. But they are capable concepts to support mountain driving and are therefore competitors to the models studied here.
- the entire kit should be lightweight and composed of high-performance components available on the market. Individuals should be able to retrofit their existing bike and equip it with efficient support. The person should also buy a frame from the market and be able to assemble his bicycle to his liking.
- the concept of speed must also be understood in order to better interpret the support.
- the driving speed is generally 15 km / h without support. With assistance, 25 km / h or 40 km / h can be achieved. In the city, for example, 15 km / h are plentiful and help limit the risk of accidents.
- the bicycle paths e.g. are not sufficiently available in Switzerland. The cars run too often with the bikes on the streets. As a result of an increase in driving speed by 8 km / h must be expected to significantly increase the braking distance, so with an increase in the risk of accidents in the city.
- the invention described herein aims to convince that support is especially useful when driving uphill. In flat urban areas it is recommended to neutralize the support. The risks of accidents are better managed. This explains the reason of a mechanical design of the system, with the possibility of pedaling with the best efficiency without support. This is also an objective of this invention.
- the solution to the problem also leads to the fact that the at least one drive with motor has at least one drive element which laterally engages an area between the tire and the hub.
- the drive has an engine with a rotational speed when the vehicle is traveling at a travel speed of 25 km / h, higher than 2800 revolutions per minute, preferably higher than 4000 revolutions per minute higher than 5000 revolutions per minute.
- motors are known in particular from model making. These are usually electric motors, but also internal combustion engines. Within the scope of the invention are all such extreme light engines.
- the weight of such a motor is less than 300 g, preferably less than 200 g, preferably less than 180 g.
- the volume of the engine is less than 2 dcl, preferably less than 1 dcl, preferably less than 0.6 dcl.
- the diameter of a main body of the engine is less than 80 mm, preferably less than 60 mm, preferably less than 45 mm.
- a characterization value motor cooling area x engine power per engine volume is higher than 5,000 dm 2 W7dm 3, preferably higher than 10,000 dm 2 W / dm 3 , preferably higher than 15,000 dm 2 W / dm 3 .
- a respective reduction gear is assigned to the motor, so that drive elements can easily set a corresponding wheel of a vehicle in motion or can rotate with it without difficulty.
- the reduction drives the rim or rims, so that the driver gets a driving assistance or an engine by means of one or more engine (s), wherein the engine speed is in an ideal range. This allows a reduction of engine torque.
- the main advantage of this system is a fundamental increase in efficiency and a drastic reduction in weight. The efficiency is fundamental to keep the weight of the charged energy as small as possible. The children will particularly appreciate the lightness of the system.
- the second advantage is a significant improvement in the heat transfer coefficient, which prevents overheating of the engine when driving uphill.
- drive elements are mainly those elements in question, preferably a frictional connection with correspondingly assigned to the wheel surfaces or non-positive connections with a chain, a belt or the like. can enter. If the drive elements engage the corresponding wheel surfaces laterally, it has proven to be advisable to design the drive elements as disc-shaped drive rollers. The role scope can then be designed accordingly. For example, it is conceivable that it is covered with a corresponding plastic, but there are many possibilities conceivable, up to a rough ceramic coating, similar to an emery paper, whereby the frictional engagement with the wheel surface is ensured.
- the drive unit of motor, reduction gear and drive element via a chain, a belt or the like. with a gear, a pulley or the like. to connect on the hub.
- this arrangement may be the gear set for the treadle, but it is also conceivable to arrange it on the same side.
- the inventive drive also supports the actual pedal crank drive, in which case a separate gear or a separate pulley can be provided.
- at least one, preferably two drives are provided on a scaffold.
- the scaffold or the two drives are designed so that a distance between the two Drive elements is mutually variable. This means that the drive (s) can be engaged by the driver himself, if desired, to support the actual driving performance of the vehicle. If this is not desired, a frictional engagement between the drive element and the wheel surface is canceled.
- pre-existing components are used on a vehicle to couple the kit. This can be, for example, already existing brake cams, wheel frame holes or brake fasteners. Especially in the latter case, the corresponding drives can be arranged on a respective lever arm, which are similar to the actual brake.
- the kit should be designed so that it is provided with a corresponding adapter for corresponding vehicles.
- the actuation of the support frame or lever arms can be done manually, pneumatically or hydraulically.
- the corresponding adjustable support frame or lever arms to be connected via known Bowden cables with a handle on the handlebar or at another point of the vehicle. Again, many possibilities are conceivable, which should be encompassed by the present invention.
- the wheel surfaces that can be attacked by the drive elements especially the lateral areas of the tire, the rim or even between the rim and hub arranged wheel rings, which are connected to the spokes. From the power efficiency ago, of course, offers the lateral area of the tire or the rim.
- the control of the drive is preferably carried out from the handlebar of the vehicle.
- a corresponding throttle grip is connected to the electronics of the engine (s).
- Another aspect of the invention relates to the power supply of the drives.
- the vehicle For the selected engines, it obviously makes sense to equip the vehicle with corresponding solar cells.
- solar cells For example, there are enough surfaces in a bicycle that can be covered with solar cells. This applies once for the area enclosed by the wheel frame, but also for the area within the rims or within the spokes.
- solar cells could be readily arranged, so that the operation of the vehicle is completely autonomous. Should the capacity of the cells be insufficient, it would also be conceivable to cover the vehicle, similar to what is known for certain BMW motorcycles.
- the required area is about 0.4 m 2 for the selected engines.
- the invention should be able to be installed in particular on an existing bicycle. But it also gives you the opportunity to integrate this concept in a new design.
- the novelty is to equip a conventional frame with as light and efficient support as possible.
- the energy must be condensed in small engines that operate at high speed.
- the reduction must be careful to keep the local forces as small as possible at each stage. This allows easy construction.
- the heat technology is realized by the choice of high efficiency motors.
- the distribution of power on two or more motors makes it possible to increase the heat transfer area, knowing that a small motor has a larger specific heat transfer area.
- a light construction that is kept as small as possible at each step, thanks to local forces.
- the power from the engine to the ground does not have to be too much vary in different reduction levels. So a light structure can be built.
- Figure 1 is a schematic representation of a kit according to the invention for mounting on a mountain bike, which is equipped with cantilever cams for the attachment of the brakes;
- Figures 2 to 7 are schematic representations of embodiments of kits for mounting on in particular a standard road bicycle, which is equipped with a frame mounting screw or a frame mounting hole;
- Figure 8 is a perspective and schematic representation of another embodiment of a kit according to the invention for the motorization of a bicycle.
- Figure 1 illustrates a kit especially for a mountain bike or city bike or cyclocross, which is equipped with cantilever mounting cams.
- the kit is therefore arranged on the cam by means of adjustable support pieces 9.1, 9.2.
- the support pieces 9.1, 9.2 of the support kit are rotatable on the cam and subjected by springs 10 a constraining force against a wired side train 6.
- the brakes they can be mounted in different ways:
- the support pieces 9.1, 9.2 are each assigned to a support frame 24.1 and 24.2, wherein the support frame 24.1 a drive 25.1 and the support frame 24.2 another drive 25.2 is arranged.
- this type of storage it is possible to change the two support frame 24.1 and 24.2 in their distance from each other, which is done by the side pull 6.
- an independent storage of the two support frame for example, on a luggage rack 8 or on a frame tube possible.
- a rim 1 is acted upon by two drive rollers 2.1, 2.2 of the drive 25.1, 25.2 side.
- the drive rollers 2.1, 2.2 are each mounted on an underarm 1.1, 11.2, on each of which a motor 4.1, 4.2 and a gear transmission 3.1, 3.2 sits. This consists of a gear 12 with 90 teeth, a gear wheel 13 with 52 teeth and a gear wheel 14 with 32.
- a maximum travel speed can be set, respectively, 40, 25 and 14 km / h.
- Each motor 4 has a small gear 16 with 15 teeth.
- the axles 11.1, 11.2 of the drive rollers 2.1, 2.2 are spaced so as to leave the zone of tires 5, fender 7 and luggage rack 8 free.
- the wired side pull 6 makes it possible to press the drive rollers 2.1, 2.2 on the rim 1, if the support is desired. However, it is possible at departure or desired free travel to loosen or cancel the train on the side of train 6, so that the drive rollers preferably spring-assisted lift from the rim 1. So the rim is completely free.
- a spring 10 On both sides is a spring 10 (only one shown), which maintains the position of the drive rollers away from the rim 1.
- the design of the spring is identical to that of Shimano V-brakes.
- the bike is thus freed of everyone, with the support kit and associated mechanical impact.
- This is an undeniable advantage compared to the BionX kit, which allows inertia to turn a mass at an unfavorable location.
- the other advantage of the invention is the fact that the rear wheel can be taken apart in the same way as if no kit was mounted on the bicycle. Hub quick release are applicable, which is not the case with kit BionX.
- the BionX requires nuts and a tightening of 40 Nm. Without that, the motor breaks its wiring by rotating the axle.
- the weight reduction afforded by the present invention results from two possibilities:
- the driving of the rim which already exists, makes it possible to ensure a high reduction ratio without the addition of additional mass.
- FIG. 2 is a sketch showing an embodiment of the invention mounted on a road bicycle.
- the wheels (28 or 29 inches) are characterized by an even higher reduction factor between the drive rollers 2.1, 2.2 and the rim 1.
- the kit attachment is so different compared to the mountain bike.
- a central brake mounting hole 17 of a frame is used to fix the new support kit.
- FIG. 2 shows a system which presses the drive rollers 2.1, 2.2 against the rim 1 by means of symmetrical lever arms 18.1, 18.2.
- the length of the lever arms is chosen so that the normal compressive force of the drive rollers 2.1, 2.2 is thus increased in comparison to the actuating manual force.
- FIG. 3 shows an alternative to pressing on how the drive rollers 2.1, 2.2 are pressed onto the rim by means of asymmetrical lever arms 18.3, 18.4.
- This system resembles the clutches of classic brakes, one 18.3 rotating around the attachment hole 17 and the other 18.4 rotating about an offset screw 19 with the intention of increasing the length of this lever arm extend.
- a connection between the two lever arms is made by a screw 20 to synchronize the movement of each drive roller 2.1, 2.2 against the rim 1.
- a single lever arm is tensioned by a spring, not shown, and the other is carried along by the synchronization screw 20.
- the screw 20 makes it possible to adjust the position of the drive rollers 2.1, 2.2 to the rim 1.
- FIG. 4 illustrates a further alternative for pressing, as the drive rollers 2.1, 2.2 are pressed against the rim 1 by means of asymmetrical lever arms 18.5, 18.6.
- This system is a further development of Figure 3 in that it does not allow the first arm to rotate about the attachment hole 17, but about a screw 21 offset from the other side. The result is thus a set of two offset rotation points 21.1, 21.2. The intention is to extend the length of the two lever arms.
- FIG. 5 shows an alternative to FIG. 2 with two offset rotational points 21.1, 21.2 in order to extend the two lever arms.
- FIG. 6 shows an alternative based on the cantilever principle, where the tensile force is centered.
- the two lever arm 18.7 and 18.8 each have a pivot point 22.1 and 22.2 on the frame and are connected at their other end in each case with a part 6.1, 6.2 of a pull cord 6.
- FIG. 7 is based on the same principle in which the motors 4.1, 4.2 are offset downwards. Again, two lever arms turn 18.9 and 18.10 to corresponding pivot points 22.3 and 22.4 on the frame.
- FIG. 8 shows a support kit with a single motor 4.3.
- This motor drives a large gear 23.1, which drives its opposite brother 23.2 to distribute the driving force on the two sides of the rim. Because the drive rollers have an opposite direction of rotation, so the two large gears can be coupled. Operation of the present invention:
- a mountain bike is equipped with the new support kit based on the present invention. Its wheels have 26 inches, the 1989 Scott Racing frame is made of steel.
- This prototype is equipped with 2 Pro-Tronik engines, model DM 2825-650.
- the two lithium polymer (LiPo) batteries are from the brand Jack Power. Each battery has the following characteristics: 500 grams, 14.8 volts and 4200 mAh effective capacity.
- the two speed regulators are from the brand robbe, model Roxxy BL-Control 960-6 60A, weighing each 60g.
- the total weight of the kit mounted on the bike is 2.9 kg and the complete bike equipped with the kit weighs 15.3 kg.
- the speed of the engines is regulated on the right with a set inverted turning handle on the handlebars.
- the twist grip is reversed because the cable pull is on its right side.
- the reason of this new configuration is to allow actuation of the shift lever without inhibitions. Access to the shift lever is thus free without increasing the diameter.
- the normal force which presses the drive rollers 2.1, 2.2 on the rim 1 is created on the left with a lever on the handlebar.
- An energy balance is determined to determine the efficiency of the various models.
- the energy balance is to be determined in two ways. One is to go through the height differences to exhaustion of the injected supply of energy. With the second, the amount of charged energy is determined by measurement.
- the brand of charger for the LiPo batteries is XPeak 230 Bai. He shows the amount of charged energy. Datasheet of the prototype, design 25 km / h for the ascent:
- the contact pressure of the drive rollers on the rim depends on the coefficient of friction. It is about selecting a material pair with an acceptable coefficient of friction in order to obtain a driving force with a reasonable contact pressure.
- the material pair aluminum / aluminum gives a coefficient of friction of about 1. In order to obtain a driving force of 10 kg, so it needs a contact pressure of 10 kg.
- the first test is carried out with aluminum drive rollers on an aluminum rim. The efficiency is very good, but the noise generated is very uncomfortable. The rim looks like a soundboard. The configuration is then improved to eliminate the noise in the transmission of the driving force.
- the drive rollers are rotated to obtain an O-ring groove on the circumference.
- the O-ring material is an elastomer such as EPDM, NBR, SBR, BR, NR (natural rubber), PVC, PUR.
- the material of the drive rollers is determined by its efficiency by being influenced by the coefficient of friction according to the rim type aluminum material, ceramic material or carbon fiber material.
- the treatment of surfaces and the consistency of the drive rollers have the goal to reduce the glide through cold, wet or snowy weather.
- the second test is performed with rubber drive rollers on an aluminum rim. Surprisingly, the efficiency is as good as in the first attempt, with the advantage that the noise is completely gone. The tests have been carried out on a 7.9% gradient.
- the metered energy balances provide an efficiency of 0.95 in both attempts to transfer the driving force from the drive rollers to the rim.
- test track On a test track of known slope, an energy balance is measured to determine the overall efficiency of the various models.
- the test track consists of three gradients and three descents. The climbs each have a height difference of about 170 meters.
- the comparison table shown below is a summary of the fundamental values of the tested e-bike models of the market, ie the state of the art, as well as the built prototype.
- the comparison table thus represents an energetic balance for each model.
- the pedaling power is a value estimated on the level of the breath with cyclist feelings. These values remain within a performance range between a walking man and a non-sporting cyclist.
- the comparison table shows the support efficiency increasing, from 0.31 to 0.82, thanks to the invention. Such an improvement in efficiency makes it possible to install a much lighter battery on the bicycle. This also results in better heat control.
- the BionX model whose efficiency does not exceed 0.31, is negatively affected by its warming. It has not been possible to drive the 510 meter altitude difference without a break.
- the BionX model consumes 346 Wh along the entire route with a top speed of 16 km / h.
- the BionX requires a long break between two climbs to let the engine cool down.
- the three climbs are driven with the invention without cooling down, except the departure time, which takes a few minutes.
- the invented model even allows the start of the three climbs with a driving speed of 21 km / h.
- the total weight of the support system of 2.9 kg is for the invention, which makes it possible to raise a height difference of 408 meters, a record.
- a weight of 3.9 kg would require a height difference of 820 meters against the 7.8 kg of the speedped for an equal height difference, at an almost equal ascent rate. This means a weight saving of 50%. It is clear that this prototype can be optimized in weight thanks to another design study.
- the overall efficiency of the prototype has been determined at 0.82.
- Pro-Tronik communicates the efficiency of 0.88 for its engine.
- the value correlated in this calculation is the transmission of the driving force on the rim, be 0.95.
- the models Dolphin and Speedped are negatively affected by the low efficiency of the hub gearbox.
- the system Flyer receives the best overall efficiency of the state of the art. Its engine can achieve an efficiency of 0.78 at 2115 rpm.
- the gear drive can have an efficiency of 0.985 and the chain sprocket with 12 teeth an efficiency of 0.95 (www.bttecos.com), giving 0.73 as overall efficiency.
- the control electronics from the field of model making is very efficient. It is possible that the e-bikes of the market also have a weak motor efficiency because of the control electronics. When electronics reach a setpoint, it is expected that such a system consumes energy.
- the market models measure either the pedaling frequency or pedaling force. This results in a calculated driving force, which is continuously regulated as a setpoint. As a result, you feel an oscillating driving force on the bike. This phenomenon is even fierce on the Dolphin model.
- the twist grip is good enough to manage the driving force.
- the driver can adjust his own need for support with the rotary handle.
- Today, the speed of the vehicles is set manually anyway. This will not be questioned again. So another question is: how to differentiate a supported bike from a motorized bike? It would be enough to install a sensor that measures the driver's activity. Once the driver is measured as active, support is provided with the twist grip. Thus, the closed loop is abandoned to save energy.
- the model engines may have ribs or thin disks on the housing to increase the heat transfer area.
- the top plate can even be an anti-rain screen.
- a heat exchanger with heat transfer fluid is also conceivable.
- the position of the motor should be such that its ventilation is optimal. The smaller the engine, the easier it is to install it on a bicycle frame. Other support alternatives can benefit from the invented basic principle.
- the small motors in the field of model making can be used to transmit a driving force at the bottom of the bicycle. It was first transmitted to the rim by the drive rollers, resulting in a reduction factor of 10.55. It is also possible to transmit this force with a belt or a chain. Pulleys can also achieve a reduction factor of 10 by laying out the first disc with a diameter of 20 mm and the second with 200 mm.
- the derailleur can be controlled so that the first pinion is reserved for assistance.
- the version with a toothed belt requires a freewheel on the hub in order to be able to pick up the support.
- Flip-flop hubs can be used to transmit the treading force on the right side and the support force on the left side.
- first sprocket of the cassette requires a freewheel on the opposite sprocket. Another condition must be met in this case: the treadle chain could not be stretched enough on its upper part and too much in its lower part. So the change could break out. To avoid this problem, you should measure the degree of tension of the chain in one place with a probe. The driving force can be limited so that it does not cancel out the change.
- a single small motor could be used up to 750W at high speed.
- the advantages are as follows: The heat transfer area is increased by distributing the trekking power to two engines. However, the first reduction is usually taken over by a gear transmission. With two motors, two teeth of the large gear are operated. This force distribution on two teeth increases the life of the transmission.
- the big gear can be made of a lightweight material. It is clear that the number of reduction stages is indefinite. Reduction alternatives, such as a continuously variable transmission, can also be used. But it is important to pay attention to efficiency. There may be other variants for driving the rim. It is about driving the rim or its periphery.
- the choice of driving through gearbox, chain or belt is not critical.
- the diameter of the motor gear is crucial. Its ideal size would be 11 mm in diameter, which would give a reduction factor of 50 for a 26-inch rim, and 55 for a 28-inch (29-inch) rim. If driving through gears makes it possible to reduce the diameter of the motor gear to 5 mm, the reduction factor doubles and becomes 100. It would thus be possible to drive the motor or motors at a speed of 20,000 rpm at a driving speed of 25 km / h, with a single reduction stage. In such a case, the accuracy of setting the circling circle becomes important.
- the chain and the timing belt in case of contamination by dust, sand and water ensure proper functioning of the transmission of the force itself.
- the driving through gearbox requires against the dust a protective measure to ensure a good functioning.
- the interface between the attached lid and the dynamic part can be protected by eyelashes while forming a comb. This is a barrier against dust and channels the water in the lower position of the wheel.
- a system with automatic lubrication can be installed to increase the efficiency of the transmission.
- Two motors of 500 W each (or of some other power) can be placed on the bike, one driving the left side and the other driving the right side of the rim.
- the possibility to increase the performance of a bike a la carte, so given.
- Pro-Tronik supplies an engine of 750 W with a thrust of 6.2 kg (motor glider), the model 3625-650 for a weight of 257 grams.
- This system could also be adapted to other means of locomotion. He is strong in assuming that light vehicles will appear in the market in terms of sustainability. Each wheel can therefore be driven.
- the driving force can even be supplied by means of an aircraft propeller mounted on each engine.
- the thrust known from model making serves as the basis for the design calculation.
- the propeller type is specified for such engine type.
- a protection is, for example in the Predicting extension of a basket to secure the machine while respecting a design curve.
- the model BionX allows the recovery of energy during braking.
- the strength of the braking force is to be programmed in the console. New it would be conceivable to develop a motorized force of braking, which is variable depending on the position of the lever. So the energy could be recovered elegantly. Recovering the energy can recharge the battery or, in the case of a pneumatic propulsion system, repress the gas.
- the support can be set in several different ways:
- twist grip With a twist grip, the support strength can be set very intuitive.
- the twist grip is equipped with an automatic return to ensure safety. This solution is very convenient when driving uphill.
- the support strength can be adjusted with a lever.
- the lever is equipped with an automatic return to ensure safety.
- the pedaling force is measured to determine the assisting force.
- the pressure on the saddle changes, and the location of the pressure on the saddle is different. From this one can adjust the support strength.
- 4. Use a probe to measure the pedaling cadence to adjust the assist level.
- the water projections created by the front wheel must be eliminated.
- the contact of the tire on the wet ground causes lateral water projections that can not be trapped with the usual fender. Water drops go past the fender on the side. Because of the driving speed, these drops will make your shoes and trousers dirty up to your knees.
- the front wheel, between the fork and the mudguard will receive strained side foils.
- This device is state of the art.
- the novelty consists of a flexible panel that extends the side tensioned cover sheets to the floor. The idea is to trap the drops of water close to the ground to protect the cyclist from dirt.
- the present invention mentions a lightweight electrical support kit.
- This concept is not limited to electrical energy. Namely, it is possible to predict a pneumatic motor (pressurized gas) or a motor fed by a cell (hydrogen / oxygen, alcohol, etc.).
- a pneumatic motor pressurized gas
- a motor fed by a cell hydrogen / oxygen, alcohol, etc.
- all the engines that spin fast can benefit from the technique presented in this text, even model-powered explosion engines.
- combustion battery it is possible to arrange it in the pipe network of the frame. Such a solution is also conceivable for the electric batteries.
