Example Embodiment

[0022] Specific embodiment one, combined figure 1 figure 2 Note: A hub gear 8 is installed on the hub, and an overrunning clutch is installed between the hub gear 8 and the hub. The inner side of the outer ring 3 of the double-ring gear has gear teeth. A fulcrum ring 5 is arranged on the inner side of the inner ring 4 of the double-ring gear, a bearing is arranged between the fulcrum ring 5 and the inner ring 4 of the double-ring gear, and a hole is provided on the fulcrum ring 5. A bracket 10 is fixedly installed on the axle 6, and a fulcrum shaft 7 is installed on the bracket 10. The fulcrum shaft 7 penetrates into the hole of the fulcrum ring 5, and the fulcrum shaft 7 can rotate in the hole of the fulcrum ring 5. The gear teeth on the inner side of the outer ring 3 of the double ring gear mesh with the gear teeth of the hub gear 8. There is a tooth 1 on the double ring gear, and a chain 2 is installed on the tooth 1.

Abstract

The invention discloses a labor-saving bicycle. A hub gear or a hub gear ring is mounted on each hub; a double-ring gear is composed of two rings with the same axial central line and different radiuses; gear teeth are arranged on the outer ring; the gear teeth of the outer ring of the double-ring gear are meshed with the hub gear or the hub gear ring; a fulcrum shaft is arranged on a support; the fulcrum shaft can be integrated with a bicycle shaft; the fulcrum force of the fulcrum shaft acts on the inner ring of the double-ring gear. As the gear teeth are arranged on the double-ring gear, the double-ring gear can be driven to rotate when the gear teeth are driven to rotate by a chain, the hub gear or a hub can be also driven to rotate, and thus the labor-saving bicycle is labor-saving when being compared with common bicycles.

Description

technical field [0001] The technology belongs to the field of vehicles, and is applicable to bicycles, electric vehicles, tricycles and the like. Background technique [0002] Bicycles are the lightest and most environmentally friendly means of transportation, but they are strenuous to ride. People do everything possible to make bicycle labor-saving, but according to present patent document, the effect that existing technology makes bicycle labor-saving is not obvious. Contents of the invention [0003] In order to improve the labor-saving effect of the bicycle, the present invention adopts the following scheme: [0004] The overall structure and characteristics of the labor-saving bicycle of the present invention are: a hub gear or a hub gear ring is installed on the hub, and an overrunning clutch is installed between the hub gear or the hub gear ring and the hub. The axial centerlines of the axle, hub, hub gear or hub gear ring coincide. Double ring gears consist of t...
