Abstract

The utility model relates to a super bicycle, which is suitable for a tool for riding instead of walking in cities, and is convenient for living a building and carrying about. The main structure is that a small wheel is fixed on an arc frame, a pedal is driven to make a connecting rod drive a crankshaft to rotate, and simultaneously a driving shaft drives a ratchet wheel to mesh with a variable speed wheel to accelerate, so that a flywheel rotates at high speed, and a driving wheel drives a rear wheel to step at high speed. The vehicle has simple structure, low cost and easy manufacture. The bicycle is safe and reliable to ride, strong in practicability and high in grade, so that riders can enjoy the trend of the times.

Description

Bicycle

The utility model relates to bicycle, is applicable to the city walking-replacing tool.Existing bicycle volume is big, is not easy to the high level carrying, and the minibike of many kind remodeling is little owing to wheel, and the stored energy amount of whipping less is little, speed unhappy, seem when riding " top-heavy ", and poor image does not satisfy city needs by bike always.And on the type of drive of bicycle, the arm of force (being that pin turns) that always is driving wheel is less than the power wheel arm of force (being the trailing wheel radius), accumulated energy flywheel (being trailing wheel) is big with the ground surface friction drag in addition, in addition, have only 100 ° in 360 ° of actual the best use of power in service of foot-operated circumference, so existing bicycle driving efficiency is not high, loss of energy is big.

The purpose of this utility model is to provide a kind of super bicycle, to realize that volume is little, speed is fast, outward appearance is luxurious and light easily folding, be convenient to high level carrying and suspension, its structural principle is: the small design front and back wheel is provided with flywheel between front and back wheel, driving wheel and change wheel are set on the flywheel, again driving wheel and wheel are in transmission connection; Adopt engine installation to connect the running of flywheel high-speed driving again, and transmission trailing wheel high speed scroll advance.

Below in conjunction with accompanying drawing structure of the present utility model and a kind of drive configuration scheme are described:

Fig. 1 is profile overall pattern of the present utility model and transmission scheme drawing;

Fig. 2 is a flywheel structure driving principle scheme drawing of the present utility model;

Fig. 3 is the utility model seat stool and arc vehicle frame folding location map;

1, a kind of arc vehicle frame 6 of design, at one end shaft clevis headstock 2 is loaded onto front vehicle wheel 1, the other end of arc vehicle frame 6 connects rear wheel 18, adorns a flywheel 11 on the arc vehicle frame 6, and flywheel 11 left sides are driving wheel 13 fixedly, the change wheel 21 of planetary wheeling mechanism is equipped with on the right, empty cover one bent axle 14 in the middle of flywheel, the right of bent axle 14 is set with axle drive shaft 20, is fixed with the ratchet drives wheel 19 of planetary wheeling mechanism on the axle drive shaft 20, be meshed with change wheel 21, following thick stick 17 both sides of arc vehicle frame are provided with stretcher 7.Bolt has connecting rod 15 on the left foot pedal 7, and an end of connecting rod 15 is captiveed joint with axle drive shaft 20; Same bolt has connecting rod 15 on the right steps 7, and the other end sky of connecting rod 15 is enclosed within on the crank shaft 22, and driving wheel 13 and back wheels of vehicle 18 are in transmission connection.

2, bicycle jaw axle 5 is set and flexibly connects, and fastening, when folding, only need tap 4 is turned round 180 °, make front vehicle wheel 1, place down thick stick 17 lower edges with wrench 3 with tap 4, unclamp again fastening wrench 3 with tap 4 by in arc vehicle frame 6 and following thick stick 17 tops.Be provided with latch 24 on the arc vehicle frame 6 of bicycle, be provided with seat rod 10 on the both sides of Che Xiagang 17, the lower end of seat rod 10 and flywheel-bracket 8 usefulness attaching partss 12 flexibly connect, and the upper end base stool 9 of seat rod 10 has pin hole 23, matches with latch 24.When needs are folding, only need mention a stool 9 seat rod 10 is moved up, make pin hole 23 break away from latch 24, get final product on the vehicle frame 16 after conveniently seat stool 9 being rested again.

When 3, riding, cocked leading 4 to required angle, and fastening again wrench 3 is turned round 180 ° smoothly; Mention a stool 9 again and move on on the latch 24, it is promptly rideable to make jack 23 be inserted in latch 24.When bipod alternately back and forth drives pedal 7, connecting rod 15 drives bent axle 14 and rotates, axle drive shaft 20 drives 19 engagement change wheel 21 accelerated services (satellite gear transmission principle) of ratchet drives wheel simultaneously, makes flywheel 11 produce high speed revolution, advances by driving wheel 13 transmission trailing wheels 18 high speed scrolls again.

In sum, its advantage of the utility model bicycle is to use small-sized wheel, makes volume extra small; Changed former bicycle transmission structure, improved transmission efficiency, realized the foot reciprocating driving, reduced idle work, made speed ultrafast; Adopted arc-shaped frame, be conducive to use light material, made vehicle body ultralight; Unique car body moulding, make outward appearance super luxurious. This vehicle type structure is simple, and is cheap, easy to manufacture, and riding safety is reliable, practical, the class height, makes the bicyclist obtain the enjoyment of the tendency of the day.
