Springs with degressive characteristic are advantageous if due to the bicycle geometry (caster, angle of the steering axle to the footprint, etc.), the restoring force of the bicycle steering, without the restoring force of the return element, due to a lifting of the bicycle geometry (caster, angle of the steering axle to the footprint, etc.), the restoring force of the bicycle steering, without the restoring force of the return element, due to a lifting of the
- Springs with progressive characteristic are advantageous if due to the bicycle geometry (caster, angle of the steering axle to the footprint, etc.), the restoring force of the bicycle steering, without the restoring force of the return element, for a negative and increasing
- progressive characteristic can cause here that the entire restoring force, so the negative restoring force of the bicycle steering and the restoring force of the return element in total, over the entire steering angle range is positive.
- the steering axle 37.4 viewed in the direction of travel, is located in front of the axle 39 of the front wheel 22 (FIGS. 25, 26).
- the fork bend, the so-called return f, to the rear instead of forward as in conventional bicycles.
- the return f is the distance from the axis 39 of the front wheel 22 to the steering axis 37.4.
- the return f is from 0 mm to 200 mm, preferably from 50 mm to 150 mm, in particular from 70 mm to 130 mm.
- the advantage of the rearward return f is that the distance g is greater than in a bicycle with the same angle b but with the return going to the front.
- the distance g is the
- a large distance g allows a passage through relatively deep potholes without turning over the
- the angular range of the steering axis 37.4 to the footprint B of the bicycle is different than in the inventive variant B1.
- Steering axle 37.4 of variant E according to the invention is at an angle b of 30 ° to 95 °, preferably 55 ° to 80 °, to the footprint B of the bicycle, starting from the footprint B.
- angles b of less than 80 °, compared to angles b of greater than 80 °, have the advantage that the bicycle
- the variant E1 according to the invention is an inventive
- variant E1 according to the invention has at least one reset element of variants D according to the invention.
- the inventive variant E1 has an angle b of 90 to 55 °, preferably from 82 ° to 60 °, in particular from 75 ° to 68 °, in
- FIG. 26 shows the side view of an embodiment of the variant E1 according to the invention with a return element of the variant D4 according to the invention. At angles b of less than 90 °, in conjunction with a steering axle 37.4 in front of the axle 39 of the front wheel 22, the bike lowers at a
- Angle b of greater than 55 ° have the advantage in the variant E1 according to the invention that the restoring force to be applied is less in the straight ahead position than in the case of smaller angles b.
- An advantage is thus a range of the angle b of 80 ° to 55 °. Particularly advantageous is a range of the angle b of 75 ° to 68 °. Because at an angle b smaller than 75 °, the bicycle frame 7 is even more compact than at an angle b smaller than 80 ° and at an angle b greater than 68 °, the restoring force to be applied in a straight ahead position is even lower than at an angle b greater than 55 °.
- the inventive variant E1 is at an angle b of 75 ° to 68 ° in combination with a return f of 70 mm to 130 mm particularly advantageous for the following reasons.
- FIG. 26 shows an exemplary embodiment of the variant E1 according to the invention with a restoring element of variant D4 according to the invention, in the form of a rubber element 24.2 with two steel flanks 24.3.
- Variant B1 in contrast to variant B1 according to the invention, in the variant F according to the invention the angle a is from 30 ° to 70 °,
- the angle ⁇ is the angle of the steering axis 37.4 to the footprint B of
- the steering axle 37.4 extends approximately through the axis 39 of the front wheel 22 (FIG. 27).
- the stub axle 37 thus has no return.
- the variant according to the invention is particularly advantageous when it is equipped with the restoring element according to the invention variant D, since this variant, due to the angle a and because of the missing return f of the steering knuckle 37, has no restoring force in straight ahead, but the front wheel 22 at slower
- the return element makes the bike spruchreuer by providing the necessary restoring force in straight ahead position.
- a front wheel 22 which has a diameter greater than 600 mm is particularly advantageous for all variants according to the invention. Even quieter are versions with front wheel diameters greater than 700 mm.
- Variant G corresponds to at least one of the other variants according to the invention or one of variants A4, A5, A6, A8 of European Patent Application EP 1 982 908 A1.
- the inventive variant G the synchronous chain 11 runs in the
- the synchronous chain 12 is the
- Hand crank 6 firmly connected to the axis 6.1 of the hand crank 6 and is located between the bearings of the axis 6.1 (FIG. 39).
- the lower synchronous chain chainring 13 is fixedly connected to the axis 8.1 of the crank 8 and is located between the bearings of the axis 8.1.
- the two synchronous chain chain 12,13 and the synchronous chain 11 are protected from dirt in the interior, which by the
- Bicycle frame tube 7.8 and the housing 7.9,7.10 are formed.
- the axle 6.1 and the axle 8.1 are rotatably mounted respectively via the bearings of the axles 6.1, 1.8.
- the housing 7.10 is bolted to the bicycle frame tube 7.8.
- the unit of the housing 7.9 and the bicycle frame tube 7.8 corresponds from the design principle in about the frame tube / housing unit of the recumbent GreenMachine the company Flevobike in Dronten Netherlands namely the upper
- the synchronous chain 11 is tensioned by the upper housing 7.9 slidably inserted in the bicycle frame tube 7.8. And slidably along the bicycle frame tube longitudinal axis 7.20.
- the housing is 7.9 via screws in oblong holes, which are parallel to the bicycle frame tube longitudinal axis 7.20, with the
- Bicycle frame tube 7.8 connected (not shown). To move the housing 7.9, the screws are loosened in the oblong holes and tightened after moving to connect the housing 7.9 firmly with the frame tube 7.8. As an alternative to screws in oblong holes, the housing 7.9 is clamped in the frame tube 7.8. Here it is
- Frame tube 7.8 slotted at the terminal point and has at least one clamping screw (not shown).
- the clamping works on the same principle of the usual clamping a seat post in the seat tube of a conventional bicycle.
- the housing 7.9 of the variant according to the invention is fixed to the bicycle frame tube 7.8
- the bicycle frame tube 7.8 according to the invention is fixedly connected to the steering head bearing tube via at least one bicycle frame tube 7.11 and to the rear wheel mount via at least one bicycle frame tube 7.12. These thus form the bicycle frame. 7
- the bicycle frame tube 7.8 also encloses the synchronizer chain blades 12, 13 (FIG. 43).
- the bicycle frame tube has 7.8 for each synchronous chain 12.13 each on the left side an opening for insertion and assembly of the respective synchronous chain blade 12,13, the axes 6.1,8.1 and the synchronous chain 11. These openings are after assembly with each a housing cover 7.23,7.24 closed.
- the axes 6.1.8.1 are each to the right of the respective synchronous chainring 12,13 in the bicycle frame tube 7.8 and in each case to the left of the respective synchronizing chain blade 12,13 rotatably mounted in the housing cover 7.23,7.24.
- the bicycle frame tube is over at least one
- Variant H according to the invention corresponds to at least one of the other variants according to the invention or one of variants A4, A5, A6, A8 of European Patent Application EP 1 982 908 A1. However, runs
- Bicycle frame tube 7.17 runs from the hand crank bearing in the
- Bicycle frame tube 7.17 is firmly connected to a bicycle frame tube section 7.14.
- This bicycle frame tube 7.18 is with a
- Synchronous chain 11 and the synchronous chainrings 12,13 uses a shaft drive.
- the claims characterize the scope of protection. The description is an embodiment of the inventive idea.
