Abstract
A bicycle without a chain comprises a front wheel, a handlebar, a horizontal bicycle frame, a bicycle seat, a vertical rear fork, a rear fork U-shaped groove, a planet gear speed increaser, pedals and a rear wheel. The horizontal bicycle frame is connected with the vertical rear fork into a whole; a U-shaped groove is arranged at the lower end of the vertical rear fork and inserted onto a bearing support; a sun gear of the planet gear speed increaser is mounted at the right end of a rear axle skin by the aid of an internal spline and fixed by an external clamp ring; a gear frame is mounted on a rear axle spline on the right side by the aid of an internal spline; two ends of the gear frame are positioned by thrust washers; four planet gears mounted on the gear frame by the aid of needle roller bearings mesh with the sun gear and an internal toothed ring; the internal toothed ring is mounted on the right side of the gear frame by the aid of thrust bearings and ball bearings; a one-way clutch is mounted on the right side of the internal toothed ring; a canal-shaped groove is arranged on the right side of an outer ring of the one-way clutch; the rear fork U-shaped groove is clamped inside the canal-shaped groove; and the pedals mesh with the gear frame by the aid of rear axles. The bicycle without a chain has the advantages of simple structure, high efficiency and labor economization.
Description
Technical field
The utility model belongs to the Personal Transporter, particularly a kind of bicycle product.
Background technology
At present, traditional bicycle is chain gear, and its drive disk assembly is many, the structure relative complex, and driving efficiency also has much room for improvement.
Summary of the invention
The purpose of this utility model is to change the structure of cycle chain transmission to overcome aforesaid drawbacks.
The technical solution of the utility model is: the utility model is by front-wheel, handlebar, horizontal frame, vehicle seat, vertical back vent, the back vent U-lag, planet gear speed increaser, pedal, trailing wheel is formed, it is characterized in that: horizontal frame is connected as a single entity with vertical back vent, there is U-lag vertical back vent lower end, U-lag is inserted on the bearing seat, the sun wheel of planet gear speed increaser is installed in hind axle skin right-hand member by female splines, fix with outer snap ring, tooth rest is installed on the back male splines on right side by female splines, locate with thrust washer at two ends, four planetary wheels are installed on the tooth rest by needle bearing, with sun wheel and internally toothed annulus engagement, internally toothed annulus is installed in the tooth rest right side by thrust baring and ball-bearing casing, free-wheel clutch is equipped with on the internally toothed annulus right side, there is canal shape groove on right side, free-wheel clutch outer ring, the back vent U-lag is stuck in the canal shape groove, and pedal is by rear axle and tooth rest engagement.
The beneficial effects of the utility model: adopt planet gear speed increaser to make bicycle become chain-driving and be gear transmission, simple in structure, high-effective and labour-saving.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is planet gear speed increaser inner structure scheme drawings.
The specific embodiment
Vehicle frame 3 levels are installed, with back vent 5 vertical weldings be one, the back vent lower end is welded with U-lag 6, trailing wheel 9 is installed on the rear axle 22 by bearing 21, with axle sleeve 11 and thrust washer 14 location, planet gear speed increaser 7 and free-wheel clutch 17 are equipped with in the trailing wheel right side, and bearing seat 20 is equipped with at rear axle 22 two ends, and the bearing seat cylindrical has canal shape groove, the back vent U-lag inserts on the bearing seat canal shape groove, fixing with locking pad 26 and nut 25, bearing 21 usefulness thrust washers 14, interior snap ring 24 and nut 23 location, the rear axle outermost end is equipped with pedal 8, vehicle seat 4 is back installation partially above trailing wheel, move after the center of gravity, the front-wheel load-bearing alleviates, and has reduced the rolling resistance of front-wheel.When pedal 8 drove planet gear speed increaser 7 and trailing wheel 9 rotations by rear axle 22, free-wheel clutch 17 combinations realized speedup, and free-wheel clutch 17 separates when sliding.
The inner structure of planet gear speed increaser 7 and principle of work: the sun wheel 12 of planet gear speed increaser 7 is installed in hind axle skin 10 right-hand members by female splines, fix with outer snap ring 13, tooth rest 15 is installed on rear axle 22 splines on right side by female splines, locate with thrust washer 14 at two ends, four planetary wheels 27 are installed on the tooth rest 15 by needle bearing 28, with sun wheel 12 and internally toothed annulus 16 engagements, internally toothed annulus 16 is installed in tooth rest 15 right sides by thrust baring 19 and ball-bearing casing 21, free-wheel clutch 17 is equipped with on internally toothed annulus 15 right sides, there is canal shape groove on 18 right sides, free-wheel clutch outer ring, the rectangular pawl 6 of back vent is stuck in the canal shape groove, pedal 8 rotates by rear axle 22 driven gear framves 15, free-wheel clutch 17 combinations, internally toothed annulus 16 is fixing with free-wheel clutch outer ring 18, tooth rest drives sun wheel 12 by planetary wheel 27 and trailing wheel 9 rotates, realize speedup, over-speed gear ratio is 1: 2.8, slide or pedal when reversing, free-wheel clutch 17 separates, and the internally toothed annulus reversing realizes sliding or the pedal reversing, planetary planet gear speed increaser axial spacing is little, only transmit torsion, no diametral load, efficient is higher.
