Abstract

A bicycle frame with a seat tube ( 1 ), a headset tube ( 3 ), a pedal-bearing housing ( 5 ), and a gear housing ( 6 ) is characterized by the fact that the pedal-bearing housing ( 5 ) and the gear housing ( 6 ) are directly connected to each other.

Claims (85)

1. A bicycle frame comprising a seat tube, a headset tube on an opposing side of the frame, a pedal-bearing housing connectable to the seat tube, and a gear housing directly connected to the pedal-bearing housing, wherein at least one of:

the pedal-bearing housing has a smaller interior space than an interior space of the gear housing; and

a rear-wheel support member is movably mounted to a portion of the frame and pivoting about an axis running through the gear housing.

2. The bicycle frame according to claim 1 , wherein the pedal-bearing housing and the gear housing are a single piece.

3. The bicycle frame according to claim 1 , wherein the gear housing is closed on either side with lids.

4. The bicycle frame according to claim 3 , wherein at least one of the lids has a plurality of parts and forms a second housing.

5. The bicycle frame according to claim 4 , wherein the second housing is provided for a gear arrangement including a pedal-bearing axle installed in a pedal-bearing housing running to a gear housed in the gear housing.

6. The bicycle frame according to claim 1 , wherein a smallest distance (A) from the headset tube to the gear housing is smaller than a measured distance (B) parallel thereto leading to the pedal-bearing housing.

7. A component for use in a bicycle frame, comprising a gear housing, a pedal-bearing housing bordering on the gear housing, and lids connected to each other forming a housing for a primary drive, wherein the housing for the primary drive is separated from the gear housing by one of the lids.

8. The component according to claim 7 , wherein the pedal-bearing housing and the gear housing form a single piece.

9. The component according to claim 8 , wherein the pedal-bearing housing and the gear housing is produced by milling and/or casting.

10. The component according to claim 7 , wherein a material of the pedal-bearing housing and the gear housing is aluminum.

11. The component according to claim 7 , wherein a planetary gear is installed in the gear housing, and pedal bearings and a pedal-bearing shaft are installed in the pedal-bearing housing, and the pedal-bearing shaft is connected to the planetary gear.

12. The component according to claim 11 , wherein at least the planetary gear is switchable.

13. The component according to claim 11 , wherein the gear arrangement includes two gearwheels and either a chain or a toothed belt.

14. The component according to claim 11 , wherein the gear arrangement is a crank gear.

15. The component according to claim 14 , wherein the crank gear has at least two crankshafts.

16. The component according to claim 11 , wherein a distance between the pedal bearing and the planetary gear is adjustable.

17. The component according to claim 7 , wherein a gearing is installed in the gear housing, and pedal bearings and a pedal-bearing shaft are installed in the pedal-bearing housing, and the pedal-bearing shaft is connected to the gearing.

18. The component according to claims 7 , wherein the housing that receives the gear arrangement is sealed.

19. A bicycle comprising the component of claim 7 and a rear-wheel support member pivotally mounted to a portion of the bicycle frame.

20. A component for use in a bicycle frame, comprising:

a gear housing;

a pedal-bearing housing bordering on the gear housing;

lids connected to each other forming a housing for the pedal-bearing housing;

a planetary gear installed in the gear housing;

pedal bearings and a pedal-bearing shaft installed in the pedal-bearing housing; and

the pedal-bearing shaft being connected to the planetary gear by means of a gear arrangement,

wherein the gear arrangement includes one of:

at least three gearwheels; and

a crank gear.

21. The component according to claim 20 , wherein the gear arrangement includes four gearwheels.

22. A component for use in a bicycle frame, comprising:

a gear housing;

a pedal-bearing housing bordering on the gear housing;

lids connected to each other forming a housing for the pedal-bearing housing;

a planetary gear installed in the gear housing;

pedal bearings and a pedal-bearing shaft installed in the pedal-bearing housing;

the pedal-bearing shaft being connected to the planetary gear by means of a gear arrangement; and

a distance between the pedal bearings and the planetary gear being adjustable,

wherein the pedal bearing is eccentrically positioned in an eccentric bushing.

23. A component for use in a bicycle frame, comprising:

a gear housing;

a pedal-bearing housing bordering on the gear housing; and

lids connected to each other forming a housing,

wherein the housing houses two non-axially aligned and spaced-apart gears and a drive chain.

24. A bicycle frame comprising:

a seat tube;

a headset tube on an opposing side of the bicycle frame;

a pedal-bearing housing directly connected to a gear housing, wherein a smallest distance (A) from the headset tube to the gear housing is smaller than a measured distance (B) parallel thereto leading to the pedal-bearing housing;

the gear housing including a gear coupled to a drive pinion;

the drive pinion being arranged in a housing formed by two lid members;

a pedal bearing arranged in the pedal-bearing housing and a pedal-bearing axle arranged in the pedal bearing;

the pedal-bearing axle being connected to the gear via at least one gear wheel; and

the at least one gear wheel being arranged in an additional housing formed by two lid members connected to each other.

25. A bicycle frame comprising:

a seat tube;

a headset tube on an opposing side of the bicycle frame;

a pedal-bearing housing directly connected to a gear housing, wherein a smallest distance (A) from the headset tube to the gear housing is smaller than a measured distance (B) parallel thereto leading to the pedal-bearing housing;

the gear housing including a planetary gear coupled to a drive pinion;

the drive pinion being arranged in a housing formed by two lid members;

a pedal bearing arranged in the pedal-bearing housing and a pedal-bearing axle arranged in the pedal bearing;

the pedal-bearing axle being connected to the planetary gear via at least one gear wheel;

the at least one gear wheel being arranged in an additional housing formed by two lid members connected to each other; and

a shaft of the planetary gear being coupled to one of the two lids of the additional housing.
