- Switchable transmissions have become indispensable in the field of motorized vehicles for the past 100 years. They are also used in drive technology on numerous machines. Very often, these are gearbox designs that work with the help of gears as a spur gear or epicyclic gear (planetary gear). However, the production technology of this transmission is usually very complicated and expensive. Since these power-transmitting gear components are usually made of steel, the weight is currently always in the focus of criticism and is to be regarded as a disadvantage. For example, lighter transmissions would Lower energy consumption.
- the novelty to be described below can be used in all imaginable product branches and, especially with regard to the low weight, is excellently suitable for use in vehicles, since fiber-reinforced plastics are used as force-transmitting components.
- land vehicles, aircraft and watercraft can be seen, which can be equipped with internal combustion engines, electric motors or other units.
- a use in vehicles is conceivable, which are powered by muscle power.
- the vehicles must be exceptionally light. The functional description of the transmission should be made for this reason, for example, on a bicycle.
- a rotatable bottom bracket with one or more chainrings is mounted on the frame, which forms the main component of the bicycle with all its mounting points for the front fork, the seat post and the rear wheel.
- a cassette consisting of up to ten different sized pinions.
- a derailleur is mounted, whose task is to guide the chain on the pinions of the cassette and to enable switching operations.
- Bicycles with a shifting system as described above are generally referred to as derailleur bicycles.
- the planetary gear is brought by the primary drive to a higher speed to withstand the forces acting.
- this design reduces the efficiency of the drive. This is to be seen as a disadvantage compared to the invention.
- similar transmissions are known for example from US 5553510, US4955247, US5924950, DE20201787U1, WO2006 / 039880 A1, US2004 / 0067804A1 and US2004 / 0066017A1.
- Their structure is usually very difficult and complex.
- the invention provides a lightweight and simply built solution for the cited type of transmission. Put all these gearboxes different translations between two parallel waves ago.
- one of the shafts is usually the drive shaft and another shaft is the output shaft.
- the drive shaft is referred to below as the input shaft.
- the output shaft is referred to below as the output shaft. If in the following only the term wave is used, then the input or the output wave is meant.
- the invention thus improves multiple transmission with input shaft and output shaft, wherein the input shaft is configured to receive the input torque and the output shaft is usually led out of the gear housing and is configured at this end for forwarding the torque to the wheels of the vehicle.
- the housing for example, Zaffenson are mounted in parallel on the input shaft and the output shaft and connected in pairs with traction means. With the help of a shift control the Glasstofftex can be coupled to the output shaft.
- the vehicle may be, for example, a bicycle, where the input shaft for receiving cranks is designed there and guided out with its two ends from the transmission housing.
- the output shaft has at its end a pinion for transmitting torque to the rear wheel.
- the vehicle may be a motorcycle in which the transmission is advantageously located behind the crankcase.
- the input shaft is suitably connected to the crankshaft.
- the output shaft transmits the torque through another machine element (eg chain, timing belt, cardan) to the rear wheel.
- Another machine element eg chain, timing belt, cardan
- Such a traction mechanism is known for example from US4,158,316.
- This gear several sprockets with different diameters are rotatable on the
- the so-called secondary ratio is formed by two further Buchstoffmanner that transmit the torque from the transmission to the rear wheel. It is beneficial if this
- Traction drives generally have a discrete center distance, which depends solely on the pitch and the length of the traction device, and the diameter or the number of teeth of the Switzerlandstoffmannmann used.
- This center distance can be described by the following formula:
- At least one component within the coupling means has the properties of a permanent magnet with a magnetic north and south pole
- the state of the coupling means changes by the variation of an additional magnetic field within or in the immediate vicinity of the coupling means, and i) during at least one switching operation the state of at least two coupling means changes simultaneously
- At least one component within the coupling means has the properties of a permanent magnet with a magnetic north and south pole and the state of the coupling means by changing an additional magnetic field within or in the immediate vicinity of the coupling means changes and that during at least one switching operation of the Condition of at least two coupling means changes simultaneously and that at least one coupling means can only transmit torques in one direction of rotation, it is impossible that is switched by a switching errorrucdlich in an idle position of the transmission, causing damage to the gearbox and possibly Injuries in a cyclist can occur. Since only magnetic fields are changed for a gear change, switching changes under load and in the state are possible.
- At least one component assumes a position at a distance relative to a toothing of a coupling body after two identically poled magnetic fields have moved toward one another, it is possible to ensure that the switching forces are reduced in comparison to the prior art.
- the positive coupling means is formed by freewheel teeth, which can engage in a toothing, the overall structure can be kept very simple ..
- a very space-saving design results when the teeth are designed as internal teeth within the coupling means.
- the freewheel teeth are arranged symmetrically to the toothing within the coupling means in order to transmit the forces uniformly.
- An advantageous control of the transmission is implemented when the change in the magnetic field is achieved by axial displacement of permanent magnets along the axis of rotation of the shaft, which is the coupling means.
- gearbox without space-related access to the interior of the waves can be constructed according to the novelty, when the axial displacement of the permanent magnet outside the input shaft is completed.
- the permanent magnets are inserted in different polarity in the spool component, so by the use of many equal parts the manufacturing costs can be kept low.
- a very inexpensive solution for the axial movement of the spool component is achieved when the spool component communicates with a traction means.
- the spool component assumes detent points within its axial movement relative to the shaft to reproducibly alter the magnetic field within or in the immediate vicinity of the coupling means.
- the switching precision is improved.
- the necessary switching forces are kept low if the positive non-rotatable connection between the shaft and the gear can be canceled with the help of the energy that was stored in the magnetic field prior to decoupling.
- a fully electronic control of the state of the coupling means can be achieved when the change of an additional magnetic field within or in the immediate vicinity of the coupling means is accomplished by electromagnets. This may be advantageous in some applications of the transmission.
- the gearbox is protected against external contamination if the frame of the gearbox is designed as a closed housing.
- the dead weight is greatly reduced when the gear ratios located between the input shaft and the output shaft are designed as traction drives with toothed belts as traction means and with toothed belt pulleys as gears.
- the traction means are reinforced by aramid, kevlar or carbon fiber materials.
- a particularly low wear on the traction means is obtained when the fiber materials of the toothed belt are coated with polyurethane.
- the skipping of the toothed belt on the toothed belt pulleys can be achieved in an advantageous manner, if the kidney-like shape of the traction means is formed under load by a straight shape of the load strand and by an increased concave curvature of the empty strand.
- the friction can be additionally reduced if at least one component that presses the traction means in a kidney-shaped form, is designed as a roller.

- the eccentric housing 50, 51 is fastened with 5 screws 29 to the housing covers 13 and 14 (not visible). Due to the rotatable mounting of the bottom bracket eccentric 21 and 22, the axis distance from input shaft 7 to output shaft 8 can be varied.
- the drive cranks 5 On both sides of the drive cranks 5 are secured by a hexagonal Aufhahme on the shaft and also fixed by long nuts 35 and a pull rod 24 located in the shaft.

- the flanged wheels 59 serve as spacers and secure the axial position of the drive pulley pulleys 60 relative to the traction means 66 during operation.
- the output traction pulleys 61 are mounted congruently with the drive traction pulleys 60 on the output shaft 8.
- the traction mechanism assemblies 56 enclose the respectively associated traction pulleys 60 and 61.
- the pulleys 60 and 61 are chosen in size and arrangement so that a uniform gradation of the individual gears is possible.
- On the bottom bracket 7 are in each case the drive pulleys 60 in the following order and number of teeth 34, 31, 41, 38, 40, 45 and 49.
- the output pulleys 61 are in the following order and number of teeth: 34, 27, 31, 25, 23, 23 and 22 attached. These numbers of teeth are chosen only as an example to explain the construction and can also be chosen differently. Depending on which output pulley is coupled to the output shaft through a mechanism to be described, one obtains a different ratio between the drive shaft and output shaft.
- the traction means are designed as fiber-reinforced toothed belts.
- the structure of the output shaft assembly 65 is shown in Figure 7a and Figure 7b.
- freewheel teeth 58 are each mounted between the Abtriebszugstoffin.
- the movement of the freewheel teeth 58 on the multi-tooth axis 23 is controlled by the switching part 87, which is not visible in this figure.
- axial wedges 96 are recessed to axially secure the inner rings of deep groove ball bearings 62 and to keep at a distance at certain positions of the shaft.
- the output shaft has 8 recesses in which the freewheel teeth 58 can perform tilting movements. By this tilting movement, a positive connection between the freewheel teeth and an internal toothing of freewheel bodies 63 are made.
- the detailed view of the Buchstoffbaueria 56 can be seen in Figure 8a and Figure 8b.
- the Buchstoff Entry 68 presses, for example with the aid of Andschreiblagern 69, the traction means 66 in the direction of Switzerlandstoffin 60 and 61. Washers 69 secure the distance to the attachment 68 and screws 67 fix the Andschreiblager 69 to the Buchstoff entry 68.
- the traction means in their construction designed so that only one Andschreiblager is necessary to press the traction means in the kidney contour.
- Both cables 76 and 77 extend in two parallel grooves on the circumference of the tension coil 72 and are secured by a clamping screw 88 or by a cylindrical end body.
- a clamping screw 88 By rotation of the tension coils in this way the trains up or unwound and it comes here to an axial movement of the switching member 87 within the output shaft 8, not shown. So that the switching member 87 can take only certain and reproducible positions within the output shaft 8 is located on the peripheral surface of the tension coils 72 locking recesses for the locking lever 73.
- the leg spring 74 presses the radial ball bearing 75 on the locking lever 73 against the undulating surface of the tension coil 72. Through the troughs on the tension coil 72 it can take a rest position only at certain angular positions.
- the leg spring 74 is located on a slide bearing 83 on a pin 81.
- a washer 84 secures the distance of the radial ball bearing 75 to the Werner 80, which is fastened with screws 82 on the Wergeophen 86.
- the radial ball bearing 70 in the interior of the tension coil 72 allows the rotational movement of the coil and a retaining ring 71 secures these bearings against displacement. Since the cable 76 must also be guided by the output pinion assembly 6, not shown, a hollow special screw 34 is necessary, which is located within the seal ring 85 and is secured by a nut 33.
- the user can thus use the cables 77 to move the shifting part 87 axially within the output shaft 8, not shown, to seven reproducible positions. If one observes the fact that five magnets 19 are additionally located on the switching part 87 on three sides, the user can adjust seven reproducible magnetic fields within the output shaft 8.
- the switching part 87 including the magnets 79 located thereon is also referred to below as a control slide 100.
- FIG. 7B the sectional plane A is shown.
- Figure 10 a illustrates a section through the output shaft in this plane A between two traction pulleys 61.
- a freewheel body 63 Per toothed belt pulley 61, a freewheel body 63 is mounted with internal teeth. It can be seen three freewheel teeth 58 arranged symmetrically within the freewheel body 63 and mounted on the multi-tooth axes 23 tilted.
- the freewheel teeth 58 are shown in this figure 10a in a non-engaged state.
- the contact surface B of the freewheeling tooth 58 is "decoupled" at a certain distance from the internal teeth of the freewheel body 63.
- the cut output shaft 8 carries on the abutment surfaces between output shaft 8 and freewheeling gear 58 small holding magnets 92, which ensure that the freewheel teeth even at External disturbances (vibrations, etc.) constantly remain in a decoupled state.
- the prerequisite here is, of course, that the freewheeling tooth 51 is made of a magnetic material.
- the switching part 87 can be seen in the middle of the figure and shown without cable 76. Also symmetrical to the center are located within the switching member 87, the rectangular magnets 79. Your Magnetic field in this configuration pushes the three freewheel tooth magnets 91 outward. Since the freewheel tooth magnets 91 are firmly embedded in the freewheel teeth 58, the tilting movement of the three freewheel teeth 58 is driven in this way.
- the multi-tooth axes are preferably made of steel and transmit the torque directly to the output pinion assembly 6. As a result, excessive material stresses are kept out of the output shaft.
- the two-sided negative polarity of the freewheeling toothed magnets 91 and the magnets 79 is shown within the figure 10a by a minus sign. This state of Figure 10a can thus be referred to as "magnetically decoupled".
- Figure IQb also represents a section through the output shaft in the plane A between two traction pulleys 61. It can be seen here, the three freewheel teeth 58 arranged symmetrically within the freewheel body 63 and mounted on the multi-tooth axes 23 tilted. The freewheel teeth 58 are shown in this figure 10b, however, in an engaged state. The contact surface B of the freewheel tooth 58 is "coupled” in a form-locking connection with the internal toothing of the freewheel body 63.
- the holding magnets 92 arranged within the output shaft 8 do not touch the freewheel teeth in this position Their magnetic field, in this configuration, pulls the three freewheel tooth magnets 91 inwardly, symmetrically about the center point, and because the freewheel tooth magnets 91 are firmly embedded in the freewheel teeth 58, the tilting motion of the three
- the internal teeth of the freewheel body 63 are designed so that the freewheel teeth can transmit only a torque, if the pulley 61 rotates clockwise.With a counterclockwise rotation of the structure works as a freewheelMagnets attract each other, is shown in Figure 10b by a plus and a minus sign. This state of Figure 10b can thus be referred to as "magnetically coupled".
- Figure IOC also provides a section through the output shaft in the plane A between Two traction pulleys 61 dar. It can be seen here, the three freewheel teeth 58 arranged symmetrically within the freewheel body 63 and mounted on the multi-tooth axes 23 tilted. The freewheel teeth 58 are shown in this figure 10c, however, as in Fig. 10a, in a disengaged state. The contact surface B of the freewheeling tooth 58 is "decoupled a distance from the internal toothing of the freewheel body 63. The arranged within the output shaft 8 holding magnets 92 touch the made of steel and thus magnetic freewheel teeth 58 and hold them firmly in position. The switching part is here This state of Figure 10c can thus be referred to as “freely decoupled.” It should be noted that this coupling means can in principle be arranged on each shaft of a gearbox Coupling means shown on the output shaft.
- FIG. 11a shows the output shaft 8 with the 7 coupling means cut longitudinally without the freewheel bodies 63 and without the traction means disks 61.
- the switching drive already described in FIG. 9 is limited to the illustration of the switching part 87 in that the magnets 79 are inserted.
- the polarity of the magnets is represented by a plus and a minus sign.
- at least one component is mounted rotatably or displaceably within a toothing.
- the middle magnet 97 is located with its positive side facing the freewheel tooth firmly inserted into the switching part 87.
- the switching member 87 is located in the illustration exactly centered under the engaged freewheel tooth 93.
- the freewheel magnet 91 is directed with its negative pole to the switching member 97 and is thus tightened.
- the contact surface B from the representation in FIG. 10 a does not become in the internal toothing of the teeth pressed freewheel body pressed. In this way, a rotationally fixed connection is made between the input shaft and the output shaft by this positive coupling means.
- at least one component in a toothing can assume a positive-locking position within the coupling means.
- Figure IIb shows the shift from this gear two into gear three.
- the engagement process of gear three is synonymous with the tilting movement of this freewheel tooth 94.
- the switching member 87 during its movement to the right.
- the overlapping magnets 99 already effect the engagement process of the freewheel tooth 94.
- the freewheel tooth 93 is still in engagement. Since due to the different ratios within the individual gear stages not both freewheel teeth can transmit forces, working in this moment one of the two freewheel teeth 93 and 94 in its freewheeling function and imperceptible jumps for the user in the internal teeth.
- FIG. 11c shows the completed shifting process from gear two into gear three. Considering the second freewheel tooth 93 from the left side, it has been pushed out of the negative pole magnet on the scarf part of the positive locking of the freewheel body. Generally speaking, within the coupling means, at least one component can hereby assume a position at a distance relative to a toothing. It can also be seen in Figurl lc the switching member 87 again exactly in the middle in its latching position under the third freewheel tooth 94.
- FIG. 11 thus shows by way of example that the novelty is advantageously additionally characterized in that at least one component assumes a position at a distance relative to a toothing, after two identically poled magnetic fields have moved towards one another.
- Figure 12 shows a gear ratio with a traction means 66 and a pulley 60 for the drive and a pulley 61 for the output.
- the traction means 66 is formed as a toothed belt and the traction pulleys 60 and 61 as a toothed belt pulleys.
- FIG. 12a shows the gear ratio in the loaded state. It can be seen that the Andschreiblager 9 do not touch the traction means in this load condition. This prevents a skipping of the toothed belt on the toothed belt pulleys, because an increase in the load leads to an increase in the wrap angle and also to an increased concave curvature of the empty strand.
- the toothed belt tries to form a convex shape by its residual stress in the load and the return strand. However, this is prevented on the empty strand side by the Andrücklager.
- the traction means is thus pressed into a kidney-like shape during load-free rotation by at least one component. On the load side, the belt clearly reaches its convex shape in FIG. 12b.
- the skipping of the toothed belt on the pulleys is thus advantageously prevented by the kidney-like shape of the traction means is formed under load by a straight shape of the load strand and by an increased concave curvature of the empty strand.
