Description

A kind of reciprocating type moving axis transmission vibration damping bicycle

The utility model relate to existing coventional type and variable speed model bicycle improvement---a kind of reciprocating type moving axis transmission vibration damping bicycle is suitable for existing all kinds of bicycles are reequiped use.

Existing all types of bicycles, no matter coventional type or variable speed model are all stepped on pivoted arm with both feet and are made circular movement by the transmission to minor sprocket of hinge wheel, chain, to realize speed change, speedup motion, all are dead axle line type of drive.Its weak point is: transmitting ratio is little, improve the speed of a motor vehicle, and the one, strengthen the power of pedaling and quicken the frequency of pivoted arm circular movement, also or by the diameter that strengthens or reduce sprocket wheel realize, still exist province's merit not laborsaving.Particularly must make circular movement, can not doing movable in a big way people for the single leg of part has increased difficulty by bike.

The purpose of this utility model is exactly to design a kind of reciprocating type moving axis transmission vibration damping bicycle in order to overcome above-mentioned the deficiencies in the prior art, and it not only can significantly improve the speed of a motor vehicle, and no matter both legs or single leg can be ridden normally per capita.

The purpose of this utility model is to realize by following mode: the shock absorber that adopts reciprocating type foot-operated arm and moving axis driving device and seat cushion to divide into is realized.Promptly be provided with extension spring between Jia Chang reciprocating type foot-operated arm and the locating dowel pin, the moving axis driving device is installed on the frame, frame is welded in the triangular frame joint, this driving device is by the left side of the overriding clutch that the roller type one way transmission is installed, the right threading arm becomes running-fit to be connected with tumbler shaft, the left threading arm is connected with overriding clutch with screw, the body of overriding clutch, be that pinion carrier is passed through the satellite gear bearing pin and linked to each other with satellite gear, satellite gear and inner gear and sun wheel engagement, frame and sun wheel, all be equipped with antifriction-bearing box between sun wheel and the tumbler shaft, sun wheel and hinge wheel are rigidly connected, the right threading arm is connected with overriding clutch with screw, is equipped with chain on the hinge wheel and cooperates composition with flywheel on the back axle.

The shock absorber that seat cushion is divided into is connected to form by screw thread and cylinder body by the gland of tool seat pad axis dowel hole, two pistons are housed in the cylinder body, from top to bottom cylinder chamber is separated into common pressure chamber, hydraulic cavities, atmospheric pressure cavity, the atmospheric pressure cavity below is provided with valve and and the integrally welded lifting shaft of cylinder body.

The utility model analytical test as calculated has following advantage: left and right pin respectively scrunches once 90 ° high effect stroke, and 90 ° idle travel (return stroke) is arranged, and is converted to rotary component expeditiously thereby obtain the power that scrunches; Reciprocating type foot-operated arm must not pass through nadir (overhead height), so can realize that foot-operated arm increases on structure, promptly when the power of scrunching equated, arm of force growth obtained rotating torque and increases, the foot-operated arm lengthening 30～45% of the comparable existing circumference formula of arm; Reciprocating type foot-operated arm is because of the effect of the overriding clutch of unidirectional rotation and reset and can be realized by mechanical energy or gas, liquid, can realize that single leg scrunches, another leg can step on reposefully be placed on the stretcher motionless; The combination that increases institute's acquisitions rotation reinforcement square by the big speed ratio (circumference formula chain-driving ratio is 2, then the planetary transmission ratio is 5.7) of planetary transmission train and the arm of force makes the speed of a motor vehicle significantly improve (being three times of the former speed of a motor vehicle, two times of the raising speed of a motor vehicle); Can improve the speed of a motor vehicle based on the vibration loss speed of a motor vehicle, vibration damping, so divide into the shock absorber that makes up by gas, liquid at former spring seat cushion, partly substitute tire air-sprung vibration damping, also the loss of the speed of a motor vehicle is needed that tire is filled up air pressure condition is provided for reducing tire and ground friction.The utility model can reach 30km/h under the condition that scrunches power increase by 30%, stepping frequency raising 25%.

Below in conjunction with accompanying drawing the utility model structure is described in further detail.
