Installed on axle two it is relative and to right angle conversion gear, a unilateral bearing 4 in the same direction is installed respectively in gear, respectively the
One unilateral bearing 41 and the second unilateral bearing 42, its rotation direction is identical and is fixed on same axis both sides, makes two gears can only
Act in the same direction on axis, and be allowed to slide, can only rotate.One right-angle steering gear is installed on semiaxis, is fixed on
Semiaxis one.Make gear on semiaxis relative in two on axis during installation and to gear be intermeshed.
When the axle on semiaxis and gear are rotated with a direction, two gears on axis also concomitant rotation, rotating
When because what is installed respectively in gear be unilateral bearing 4 in the same direction, now the first unilateral bearing 41 on axis makees diligent band to axle
Dynamic axis rotates, while the second unilateral bearing 42 is driven, axis is not made diligent；Axle and gear on semiaxis is with another side
Two gears on axis also concomitant rotation, because what is installed respectively in gear it is unilateral bearing in the same direction when rotating to when rotating
4, now the second unilateral bearing 42 on axis makees diligent drive axis rotation to axle, while the first unilateral bearing 41 is driven, no
Axis is made diligent；Though therefore the gear on semiaxis and semiaxis to that direction rotate when, can all drive axis with a side
To rotation.Such as think the rotation direction of change axis, need to only change the installation direction of unilateral bearing 4.Axis and bicycle

Two are clamped to dislocation with the gear turned left, the respectively first 154 and second gear 155 in the same direction of gear in the same direction.Rack lower end
It is fixed in same fixed plate 156, then connects a fixed slip bar 157 altogether, the lower end of the slider is provided with strap sliding block 158.Two teeth
One unilateral bearing 4 that can turn left dynamic, i.e. the 3rd unilateral bearing are installed respectively in wheel.One is corresponded on per toothed rack unidirectionally can be left
Rotating disk, two left-hand rotation ratchets are mounted side by side on same power transmission shaft 159, and power transmission shaft 159 passes with the lower end of driving section 15
Dynamic slip-knot connection.
The upper end of driving section 15 is pushed by vehicle body, pressure can make rack walk downwards, drive two ratchets to rotate,
One of them first gear 154 in the same direction unidirectionally to turn left is turned right by the negative side that the first rack 152 drives, and drives power transmission shaft
159 right-hand rotation acting outputs, because the second rack 153 is reversely to install, the second gear 155 in the same direction that another unidirectionally turns left is by second
Rack 153 drives left-hand rotation, at this moment turns left and is not done work for idle running；Vehicle body, which is depressed into limit, can go up bounce-back, during bounce-back when pushing
Acting drives two ratchets to rotate on the contrary, in resilience rack can be made to walk upwards, and descending contrast, because of second
Rack 153 is to fill, the opposite direction that at this moment second gear 155 in the same direction unidirectionally to turn left is driven by the second rack 153 relatively
Turn right dynamic, drive power transmission shaft 159 to turn right dynamic acting output, because the first rack 152 is reversely to install, another unidirectionally turn left the
One gear 154 in the same direction drives left-hand rotation by the first rack 152, at this moment turns left and is not done work for idle running；So as to reach unified acting of turning right
Output.
Under steam, wheel 3 can fluctuate car when road surface rises and falls, and wheel 3 makes the lower end of driving section 15 float, buoyancy meeting
Gear is walked upwards, drive two ratchets to rotate, the second gear 155 in the same direction that one of them unidirectionally turns left is by the second tooth
The negative side that bar 153 drives turns right, and drives power transmission shaft 159 to turn right and moves acting output, because the first rack 152 is reversely to install,
Another first gear 154 in the same direction unidirectionally to turn left drives left-hand rotation by the first rack 152, at this moment turns left and is not done work for idle running；Car
Wheel 3, which floats, to be pressed onto limit and can fall bounce-back after rise, and acting in resilience on the contrary, can make gear walk downwards when falling during bounce-back, drive
Two ratchets are rotated, with up contrast, filled because the first rack 152 is relative, at this moment one is unidirectionally turned left
First gear 154 in the same direction is turned right by the negative side that the first rack 152 drives, and drives power transmission shaft 159 to turn right and moves acting output, because
Second rack 153 is reversely to install, and another second gear 155 in the same direction unidirectionally to turn left drives left-hand rotation by the second rack 153, this
Shi Zuozhuan does not do work for idle running；So as to reach unified acting output of turning right.
Either vehicle body pushes and resilience in a word, and wheel 3 floats and fallen after rise acting, can all drive one direction of output shaft
Output acting.Output work is passed to bicycle by buffer storage equilibrium to carry out utilizing driving.
No chain labour-saving bicycle provided by the invention, provided with some right-angle steering gear-boxes.Right-angle steering gear-box is set
There are axis and semiaxis, two opposite gears are equipped with axis, be also provided with a gear on a semiaxis, the gear on semiaxis
