The specific embodiment

Use later-model embodiment to further describe below in conjunction with accompanying drawing to this.

No chain is ridden car instead of walk by wheel 1, reciprocator 2, vehicle frame 3, pedal 4 with brake and 5 form.

Wheel 1 comprises a front-wheel 11 and two trailing wheels 12.The outer ring 234 and front-wheel 11 flush fits of unidirectional flywheel in the reciprocator 2.

Vehicle frame 3 comprises front-wheel support 31, rotating shaft 32, front running board connecting rod 33, king-rod 34 and hind axle 35.Front-wheel support 31 welding one end is welded on the shell 21 of reciprocator 2, and the other end is with on the bolt front running board connecting rod 33, and front running board connecting rod 33 is connected through rotating shaft 32 with king-rod, and king-rod is connected with hind axle 35 through bearing.

Every pedal 4 is made up of front running board 41 and back step 42 two parts, and front running board and back step separate, and all there is back-up ring at the edge.Said front running board 41 is fixed on the two ends of front running board connecting rod 33, and is not movable.Back step 42 is connected with moving bar 25 in the reciprocator 2.Moving bar 25 is the bar of cranking arm, and is as shown in Figure 3, can do around the center shaft of front-wheel ± 15 degree rotations.

Reciprocator's bag, change-gear set 22, unidirectional flywheel 23, side steering 24 and moving bar 25.Like Fig. 4, shown in Figure 5, moving bar 25 links to each other with back step 42, change-gear set 22 be about two groups, every group has 4 grades of speed change transmissions, gears at different levels are connected through cylindrical bearing with center shaft, intermesh between each gear.The primary pinion of change-gear set and moving bar 25 are coaxial, inner ring 231 engagements of final stage gear and unidirectional flywheel.Change-gear set can be amplified to the rotational angle that moves bar 15 degree more than 360 degree, and promptly moving bar rotates 15 degree, and inner ring rotates more than the circle.Said inner ring 231 has two, respectively with about the final stage gear mesh of two change-gear sets.

In conjunction with shown in Figure 6, a plurality of jacking blocks 233 that have spring 232 are housed on the inner ring 231 of unidirectional flywheel, the internal spline of the end of jacking block and unidirectional flywheel outer ring 234 matches; Captive joint with front-wheel 11 in the outer ring 234 of unidirectional flywheel.The structure of jacking block and spring assembly has guaranteed that outer ring 234 can only be towards anticlockwise motion among Fig. 6.When inner ring 231 rotated counterclockwise, jacking block withstood the internal spline of outer ring, made inner ring drive the outer ring and rotated; When inner ring clockwise rotated, to the extruding of spring 232 directions, spring 232 compressed the internal spline of outer ring with jacking block, and jacking block is avoided the internal spline of outer ring, and inner ring is in neutral state always, can not promote the outer ring.

Side steering 24 in the reciprocator is made up of left bevel gear 241, right bevel gear 243 and more than one transition bevel gear 242.Three gears intermesh, and make the rotation direction of left bevel gear 241 and right bevel gear 242 just in time opposite.Its effect is, and is as shown in Figure 3, steps on when back step on one side, and the pedal of another side rises.

Because unidirectional flywheel has guaranteed that front-wheel can only rotate forward, therefore no matter left foot is stepped on still is that right crus of diaphragm is stepped on, and front-wheel can only roll forward, and can not rotate backward.

As scheme to brake and 5 be installed on the hind axle 35, form by brake facing 51 and brake wheel 52.Brake wheel 62 is fixing with hind axle 36, between brake facing 51 and the brake wheel 52 slit is arranged.Brake facing 51 is processed for rubber, when the user steps down on the brake facing 51, brake facing and brake wheel is rubbed, and plays the effect of deceleration.

As the beginner, not easy-to-use sole is held direction, and the no chain car of riding instead of walk can increase handle and conveniently controls.As shown in Figure 2, above rotating shaft 32, extend a vertical rod 36 and handle 37, both hands buttress handle 37, both have been convenient to keep one's balance, and also are convenient to turn to.Captive joint with block 361 in vertical rod 36 bottoms, front-wheel support is welded on the block 361, drives front-wheel and handle and rotate synchronously.

Further, as shown in Figure 7, rotating shaft 32 inside can also be provided with torsion spring 38, and forward during straight-line motion, torsion spring is a relaxation state at front-wheel.When front-wheel turns to, no matter be left or to the right, all can make torsion spring 38 hold power, when external force was removed, torsion spring resetted rotating shaft, kept straight ahead.

This nothing chain car of riding instead of walk is light laborsaving, and left and right sides heel is alternately stepped on back step, and the no chain car of riding instead of walk is advanced, and gait of march is very fast, and double-legged sharp may command direction is easy to learn, but user's at high speed gains the essentials.And the tricycle structure ratio is easier to control direction, and it is also flexible relatively to turn.The no chain car of riding instead of walk has satisfied that young man is curious, the nature of sensation seeking, for body-building apparatus market has increased a kind of new selection.
