specific Embodiment approach 1

[0022] Specific implementation mode one, combining figure 1 figure 2 Explanation: The 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 double-ring gear outer ring 3 has gear teeth. The inboard of double ring gear inner ring 4 is equipped with fulcrum ring 5, bearing is arranged between fulcrum ring 5 and double ring gear inner ring 4, and hole is arranged on the fulcrum ring 5. Support 10 is fixedly installed on the axle 6, and fulcrum shaft 7 is installed on the support 10, and fulcrum shaft 7 penetrates in the hole of fulcrum ring 5, and fulcrum shaft 7 can rotate in the hole of fulcrum ring 5. The gear teeth on the inner side of the double ring gear outer ring 3 are meshed with the gear teeth of the hub gear 8 . A cog 1 is arranged on the double ring gear, and a chain 2 is installed on the cog 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...
