Abstract
The utility model discloses a high-speed, safe and portable bicycle, which comprises a frame and front and rear wheels and splash guards disposed on the frame. The frame is provided with a front shaft, a middle shaft and a rear shaft, which are all planet gear shafts. Each planet gear shaft is formed by two planet gear sets meshed with each other. Each planet gear set comprises a gear ring, planet gears and a planet carrier; the circumference of the disc-shaped planet carrier is provided with six planet gear installing holes uniformly; the center of planet carrier is provided with a gear shaft; the planet gears are installed in the installing holes of the planet carrier in a spaced manner and are meshed with the gear ring; and the gear shaft is meshed with planet gears disposed on another planet carrier set. The bicycle is simple in structure, portable, labor-saving, and high-speed, and enables comfortable and safe riding.
Description
Technical field
The utility model relates to a kind of bicycle, relates in particular to a kind of high-speed secure portable bicycle.
Background technology
At present, the motion of traditional bicycle is by acting on the power of pedaling on the pedal, drive axis, fixing a chain sprocket on the axis, and through chain sprocket, chain drives the rear flywheel rotation, realizes that the back-wheel drive bicycle advances.Transmission shaft all adopts ball bearing of main shaft to realize rotating, and bearing exists the life-span weak point like this, and power transmission is 1: 1, and therefore not light in the process of riding, moving velocity is slow, and speed is slow especially when especially on the ramp, going, and energy consumption is high.
Summary of the invention
The purpose of the utility model is to solve the defective that prior art exists, and provides a kind of simple in structure, light laborsaving, speed is fast, the comfortable safe high-speed secure portable bicycle of riding.
The described high-speed secure portable bicycle of the utility model comprises: vehicle frame is arranged on front and back wheel and mudwing on the vehicle frame; Described vehicle frame is provided with front axle, axis, rear axle, and described front axle, axis and rear axle are compensating-gear shaft, and described compensating-gear shaft is made up of two intermeshing compound planet gears; Described compound planet gear is made up of gear ring, planetary wheel and pinion carrier; Described pinion carrier is a disc, and circumferencial direction evenly is provided with 6 planetary wheel mounting holes, and circle centre position is provided with gear wheel shaft; Described planetary wheel is installed in the mounting hole of pinion carrier at interval, and is meshed with gear ring; Planetary wheel engagement on described gear wheel shaft and another group pinion carrier.
Aforesaid high-speed secure portable bicycle is characterized in that: described vehicle frame is welded by aluminium alloy pipe.
Aforesaid high-speed secure portable bicycle is characterized in that: described mudwing is that glass-felt plastic is processed.
The utlity model has: simple in structure, light laborsaving, speed is fast, the comfortable safe advantage of riding.
