Hand-rocking bicycle provided with high-low gears speed regulation transmission mechanism

Abstract

The invention provides a hand-rocking bicycle provided with a high-low gears speed regulation transmission mechanism, and relates to a bicycle. Existing hand-rocking bicycles almost have no perceptions of gears, and the speed is controlled through the hand speed. The hand-rocking bicycle comprises a bicycle body, a bicycle front wheel, a bicycle rear wheel, a seat, a hand-rocking handle, a speed regulation transmission mechanism, a steering mechanism, a pedaled braking device and pedals; the bicycle rear wheel or the bicycle front wheel is a driving wheel, the speed regulation transmission mechanism comprises a sun wheel and a planet wheel, wherein the sun wheel is fixedly connected with the bicycle body, and the planet wheel is connected with the sun wheel in an engaged mode and can be separated from the engagement; the planet wheel is connected with a bicycle shaft of the driving wheel through a transmission assembly, a connecting rod is fixedly connected to the lower end of the hand-rocking handle, and the connecting rod is connected with a central shaft of the planet wheel through a bearing; and the lower end of the connecting rod is connected with an axle of the driving wheel through a single-way bearing, and the driving wheel is connected with the axle through a single-way bearing. According to the hand-rocking bicycle provided with the high-low gears speed regulation transmission mechanism, shifting and speed regulation between a high speed gear and a low speed gear can be achieved conveniently, adapting to different occasional application such as plain travelling and slope climbing is facilitated, shifting of the gears is convenient, and operation is simple.

Description

technical field [0001] The invention relates to a hand-operated bicycle with a speed-regulating transmission mechanism for high and low gears. Background technique [0002] At present, there is basically no concept of gears on hand-operated bicycles, and the speed is controlled by the hand speed. In actual use, it is desirable to have greater force and lower speed when climbing a slope, and the transmission is relatively small; Higher speed and less effort require a large transmission ratio. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to perfect and improve the existing technical solutions, and to provide a hand bicycle with a high-low gear speed regulating transmission mechanism for the purpose of realizing high and low gear speed regulation. For this reason, the present invention takes the following technical solutions. [0004] A hand bicycle with high and low gear speed regulating ...
