However, each chainring of the known lock-tooth type or cassette flywheel is adjacent to and fixed in the manner of being sleeved on the threading shaft of the ratchet, and the inner diameter of the bushing hole in the middle of the smallest toothed plate is affected by the outer diameter of the threading shaft. The limit cannot be reduced, so the smallest chainring of the flywheel cannot be made smaller due to the above limitations. Generally, the smallest chainring is about 14 teeth. At present, the smallest chainring is found to be 11 teeth, but even if the smallest chainring is only 11 teeth, it still cannot meet the requirements. Needed for small wheel bike riders

Embodiment Construction
[0040] Please also see Figure 1-5 As shown, the flywheel 1 of the present invention is applied to the threaded surface 210 of the wheel hub 20 one end 21 of a bicycle rear wheel 2 as an example, and the flywheel 1 is combined with the wheel hub 20. Pass through, and the two ends of this axle shaft 22 are fixed with vehicle frame again. The Flywheel 1 contains:
[0041] An intermediary wears a suite of 10, such as Figure 4-5 As shown, it is hollow, and the two sides protrude axially outward respectively and are a first hollow shaft 100 and a second shaft 101. The shafts of the first and second shafts 100, 101 The center overlaps with the axis of the intermediary sleeve 10. The outer peripheral surfaces of the first and second sleeve shafts 100, 101 are respectively a first sleeve segment 102 and a second sleeve segment 104. The tooth structure 107, the tooth groove of the ratchet structure 107 is axially extended. The end surfaces of the first and second sleeve shafts 10...

The flying wheel comprises a hollow medium external member and fluted discs. The fluted discs are sleeved and fixed out of the medium external member. The fluted discs are arranged according to the size of the diameters in order. The fluted disc end of the medium external member with the minimum diameter is provided with a joint hole and a tail end gear wheel. The tail end gear wheel is arranged at the outer side of the joint hole. The center of the circle of the tail end gear wheel is provided with a central hole. The tail end gear wheel faces the joint end of the joint hole and is embedded in the joint hole. The joint end and the joint hole are joint and fixed in a joint means. The joint means can limit the connection movement of the tail end gear wheel and the medium external member. The tail end gear wheel is sleeved out of the medium external member to reduce the outer diameter of the tail end gear wheel, improve the gear wheel ratio and improve the speed of the vehicle.
Description
【Technical field】 [0001] The invention provides a flywheel for a vehicle, especially a flywheel structure for a vehicle that can make the outer diameter of the end gear of the flywheel smaller, increase the gear ratio of the vehicle, and increase the riding speed. 【Background technique】 [0002] The flywheel of the bicycle is connected to the hub of the rear wheel, and the flywheel and the front sprocket are connected by a chain. The front sprocket is driven to rotate by stepping on the pedal, and the flywheel and the rear wheel are driven to rotate by the chain to make the bicycle move forward. The flywheel is mainly composed of a plurality of large and small toothed plates with different outer diameters and matching different numbers of teeth and a ratchet. The ratchet makes the large and small toothed plates only rotate in one direction and cannot be reversed. Arranged from largest to smallest. The rider can control the front and rear derailleurs through the two shift ha...
