Abstract
The utility model relates to a speed variation device of a bicycle which comprises a medial axle and a rear axle of the bicycle. An active gear drives a driving chain wheel to realize the speed variation via a driven gear, a driving gear and a second driving gear. The driving chain wheel connects with a chain with a flywheel. The flywheel and a landing wheel form an integral entity and are mounted at the rear axle of the bicycle. The second driving gear, the driving chain wheel and the active gear have the same shaft. The driving gear and the driven gear have the same shaft. The utility model, a speed variation device of a bicycle, adopts such a configuration as follows: The active gear is direct installed at the medial axle, and the driven gear and the driving gear perform a mesh movement with the active gear to drive the chain wheel at a rate of 1:4 so as to realize the speed variation. The utility model is characterized in a simple and compact structure, a lower manufacture cost and an accelerating course subject to the force level for the regulation which can create an easier and laborsaving riding.
Description
Technical field
The utility model relates to a kind of bicycle assembly, particularly relates to a kind of derailleur.
Background technology
Existing derailleur adopts the cone pulley form usually, thereby it is to adopt group chain device that chain is in to realize speed change on the different sprocket wheels, the transmission system complex structure of this form, the manufacturing cost height, and a chain is gyrated between different sprocket wheels, fall chain easily, especially owing to rotation ratio designed on driving is excessive, make the user have to consume more muscle power in the process by bike, extremely effort.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technological deficiency, provides a kind of simple in structure, compact, low cost of manufacture and labour-saving derailleur by bike.
As follows for realizing the technical scheme that the purpose of this utility model adopted:
A kind of derailleur, comprise bicycle middle shaft and bicycle rear axle, it is characterized in that: on the above-mentioned bicycle middle shaft driving gear is installed, this driving gear by driven gear, transmission gear and again transmission gear drive driving chain wheel and realize speed change, driving chain wheel is connected by chain with flywheel, and flywheel and landing wheel one also are installed on the bicycle rear axle; Above-mentioned transmission gear again, driving chain wheel are coaxial with driving gear, and transmission gear is coaxial with driven gear.
Derailleur of the present utility model, employing is the direct mount driving gear on bicycle middle shaft, utilize the drivings device such as driven gear, transmission gear of the motion that is meshed with driving gear, rotate with 1: 4 rotation proportional band movable sprocket, thereby realize acceleration.This is simple in structure, compact, low cost of manufacture, and accelerator changes along with user's firmly situation, pedal then the speed of a motor vehicle is fast soon, pedal then the speed of a motor vehicle is slow slowly, very convenient, and more laborsaving in the process by bike.
Description of drawings
Fig. 1 is the drive mechanism simplified schematic diagram of the utility model derailleur.
The specific embodiment
Derailleur of the present utility model, comprise bicycle middle shaft 1 and bicycle rear axle 12, driving gear 2, transmission gear 5 and driving chain wheel 6 again are installed on bicycle middle shaft 1, driving gear 2 and transmission gear 5, driving chain wheel 6 are installed in the both sides of axis axle skin 9 respectively again, transmission shaft skin 10 both sides at transmission shaft 11, driven gear 3 and transmission gear 4 are installed respectively, above-mentioned driving gear 2 and driven gear 3 engagements, transmission gear 4 and transmission gear 5 engagements again, transmission gear 5 is connected with driving chain wheel 6 again, thereby realizes speed change.6 of driving chain wheels pass through chain 8 and are connected with flywheel 7, and flywheel 7 and landing wheel 13 one also are installed on the bicycle rear axle 12.
