Abstract
The invention provides a bicycle speed changer in CVT (Continuous Variable Transmission), which is used for changing original chain transmission of a bicycle into gear transmission according to a principle of an automobile differential mechanism and realizing a CVT effect which cannot be achieved by the chain transmission. The bicycle speed changer is characterized in that pedal treading by a person is used as power input through the gear transmission, power is transmitted to a differential mechanism shell 5 through an axle shaft 2, and the power is averagely transmitted to a left axle shaft and a right axle shaft through a planetary gear 6 and a planetary gear 7 by the differential mechanism shell 5 under a normal condition; when the rotation of a rotating disc 4 is controlled by a hydraulic friction device, residual power is used as the traveling power of the bicycle by being transmitted to the right axle shaft 8 through the planetary gears by the differential mechanism; the power is obtained by a generator 2 from the rotating disc 4 through a gear device and is used for generating electricity under a situation that the normal and smooth traveling is not influenced. The bicycle speed changer has the characteristics that the reasonable distribution of a torque moment can be carried out through the differential mechanism, the CVT of the bicycle is realized, and the defects that tooth jumping is brought by the chain rotation, the speed change impact force is large, a chain is easily broken, and the speed change is not smooth are avoided; the residual power can be utilized for generating the electricity, and a generator device and a brake device can be conveniently installed.
Description
Technical field
The present invention relates to the change-speed box with diff, is a kind of safe, efficient, stable change-speed box
Background technology
In existing bicycle, most change-speed boxs are all chain gears, and the exposed easy pollution clothes of chain often has and beats in speed change, unstable and easily pull apart chain, cause serious safety misadventure.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of change-speed box of safe, efficient, stable electrodeless variable-speed.
The technical solution used in the present invention is: by the intervention of diff, carry out the speed of continuous control bicycle by the rotating speed of continuous control rotating disk, safety is easy to operate, and speed range is large.
The useful fruit effect of the present invention invention is: can by this change-speed box safety, stable, make bicycle realize stepless change continuously, and can there is very strong transplantability, be for example transplanted on exercise bike etc.
Brief description of the drawings
Below in conjunction with drawings and embodiments, this invention is described further.
Accompanying drawing 1 is structural representation of the present invention.
1, dynamical axis, 2, electrical generator, 3, fluid power friction gear, 4, rotating disk, 5, diff shell, 6, planetary wheel, 7, planetary wheel, 8, right axle shaft (power take-off shaft).
Detailed description of the invention
On the basis of dynamical axis 1 normal input power, by controlling fluid power friction gear 3, rotating disk 4 is applied to friction, control rotary speed, and then by planetary wheel 6,7, power is exported from right axle shaft 8, can realize stable electrodeless variable-speed.
Claims (1)
1. the bicycle speed-varying unit of a continuously variable, it is characterized in that: people steps on stretcher, input as power by gear transmission, by semiaxis 1 by transmission of power to diff shell 5, under normal circumstances, power is passed through Planetary wheel 6 by diff shell 5, power is on average transported to left and right semiaxis by 7, in the time of the rotation of fluid power friction gear control rotating disk 4, diff passes to right axle shaft 8 by excess power by planetary wheel, as bicycle running power, do not affecting under the condition that normal smoothness travels, electrical generator 2 obtains power by wheel word from rotating disk 4 and generates electricity.
