Description
The utility model belongs to technical field of bicycles, specifically a kind of stepless gearing and energy accumulating bycicle with hydraulic commission that increases moment of torsion by hydraulic transmission.
As everyone knows, bicycle has had centuries history so far from its invention, through continuous differentiation and improvement for many years, its structure is increasingly rationalized, performance is constantly improved, function also is on the increase, but it is not so far also thoroughly on structure, change on the principle, still follow the pattern of in the past leaning on mechanical transfer power, although occur the bicycle of some different styles and purposes in recent years, as cross-country car, mountain bike, full landforms car, new bicycles such as city car, it only is not on material, very big improvement has been arranged on the color, do not carried out substantial change.Along with improving constantly of the people life and the level of consumption, people are also more and more higher to the requirement of the performance of existing bicycle and style.
The purpose of this utility model provides a kind of stepless gearing and energy accumulating bycicle with hydraulic commission that utilizes the planetary wheel speed increasing mechanism and increase moment of torsion by hydraulic transmission.
The purpose of this utility model is achieved in that it comprises bicycle body, axis sprocket wheel, chain and rear flywheel, it is characterized in that being provided with a planet gear increaser structure at the axis place of stretcher, wherein stretcher is connected with the input shaft of planetary wheel speed increasing mechanism, and the output shaft of planetary wheel speed increasing mechanism is captiveed joint with the axis sprocket wheel of bicycle, and the axis sprocket wheel links to each other with rear flywheel by chain; Rear axle is provided with one by hydraulicdriven turbine transformer, this turbine transformer is by mutual cooresponding pump impeller, turbine, the cavity and the seal closure formation of liquid oil formed and be full of to guide wheel, the rear axle that links to each other with rear flywheel is captiveed joint with pump impeller by the spline housing and the spline of its end, turbine is captiveed joint with the back rim by gusset, on rear axle, also be set with an axle sleeve, one end of axle sleeve is captiveed joint with vehicle frame, and the other end is bearing on the spline housing by bearing, guide wheel is fixed on the middle part of axle sleeve, be evenly distributed with centrifugal arcuation blade in the inboard of pump impeller, equally also be evenly distributed with centrifugal arcuation blade in the inboard of turbine, just centrifugal direction and pump impeller is opposite, be evenly equipped with in the inboard of guide wheel both sides respectively with pump impeller and the corresponding guide card of turbine.Its principle of work is: when the cyclist drives the axis rotation by stretcher, by planetary wheel speed increasing mechanism speedup, the rotating speed of axis sprocket wheel can increase 20-60 doubly, pass through chain this moment, rear axle, the pump impeller of spline housing captive joint is the while high speed revolution also, then the power fluid of pump impeller inboard is also stirred simultaneously, and throw away along its inboard uniform formed centrifugal passage of centrifugal arcuation blade (cavity excircle), the power fluid that throws away enters turbine and impulse turbine blade, throw away from the other end passage (cavity inner periphery) of turbine blade simultaneously and enter guide wheel, opposite side from guide wheel turns back to pump impeller inside again, causes power fluid along above-mentioned circulating motion.Because guide wheel is fixed on the vehicle frame by rear axle housing, no relative motion, so can not rotate, at this moment impact the power fluid of guide wheel and give moment of reaction of turbine, the resulting moment of turbine this moment is the reaction torque sum that the pump impeller input torque is added guide wheel, at this moment turbine begins to quicken rotation on the impact of power fluid and the basis that continues to increase, also begins to rotate by rim behind the gusset bonded assembly (being rear wheel) simultaneously, and this bicycle travels gentle acceleration.
The simple mechanical drive of rear axle is the hydraulic transmission that the planetary wheel speed increasing mechanism matches with turbine transformer to the utility model in the existing bicycle owing to changing, variation by resistance to motion, energy automatically regulating moment of torsion, so the front and back change-speed box and the cone pulley mechanism that have omitted existing derailleur, realize stepless change, thereby being through with in the past, variable speed bicycle has fundamentally reduced because the resistance that mechanical wear produced by the history of mechanical transfer power and speed change.Advantages such as that the utility model also has is rational in infrastructure, attractive in appearance, laborsaving, long service life, applied range.
The utility model is described in further detail below in conjunction with accompanying drawing:
