As shown in Figure 1 and Figure 2, the utlity model has vehicle frame 4, front and back wheel 1 ' and 1, the upright beam 42 of vehicle frame passes through two floors, 12 connections, one axle sleeve 22 of weld together with it, and the axis 18 that rotates around it is installed in this axle sleeve, is provided with a pair of antifriction-bearing box 20 between axle sleeve and the axis.Two free ends of the axis that stretches out from axle sleeve are installed with left and right ratchet-gear wheel 21,23 respectively, are installed with the sprocket wheel 6 that rear wheel 1 is rotated on the right free end of axis.Its mounting means is at the affixed left spindle nose cap 19 of the left free end of axis, left ratchet-gear wheel 21 is threaded with left spindle nose cap 19, so left ratchet-gear wheel 21 drives axis 18 rotations by left spindle nose cap 19, and in like manner right ratchet-gear wheel 23 drives axis 18 rotations by right spindle nose cap 7.Different with left spindle nose cap is to have flange on the right spindle nose cap 7, and sprocket wheel 6 is fixed on this flange, realizes the purpose that the right free end of axis and sprocket wheel 6 are affixed.As Fig. 1, shown in Figure 10, install on the chain stay 43 of vehicle frame one have two sprocket wheels respectively with sprocket wheel 6 and rear wheel on the corresponding chain sprocket 3 in sprocket wheel 1a position, two sprocket wheels of this chain sprocket 3 respectively by chain 2 ', 2 be connected with sprocket wheel 1a on the rear wheel with sprocket wheel 6.An above-mentioned left side, right ratchet-gear wheel 21,23 external tooth respectively and be arranged at its fwd, be positioned at vehicle frame both sides, left side perpendicular to the ground up-and-down movement, right rack- plate 17,10 are meshed, a left side, right rack- plate 17,10 are equipped with a left side respectively, right pedal roller 15,9 and left, right steps 16,8, on a left side, right rack- plate 17,10 periphery is provided with respectively to have track to make rack-plate do alternatively up and down in its track reciprocating, lower port is sealed and the left side that rack-plate is spacing, right guide pipe 13,5, a left side, right guide pipe 13, have respectively on 5 that above-mentioned pedal roller is done the alternatively up and down crank motion and the rectangular groove 13a that passes through, 5a.As Fig. 1, Fig. 3, shown in Figure 4, described left and right guide pipe 13,5 is individually fixed in chain stay 43 places of the crossbeam 41 and the vehicle frame of vehicle frame by attaching parts 24, attaching parts 24 is made up of left and right arc sheetmetal 24b, 24c, aglet bar 24a, binding bolt 24d, the inner arc surface of left and right arc sheetmetal 24b, 24c and the crossbeam 41 of vehicle frame match, and its exterior arc surface is with aglet bar 24a and is locked by binding bolt 24d.Attaching parts 24 also can be by respectively with affixed two couples of angle steel 24e, the 24h up and down of left and right guide pipe, a pair of binding bolt 24f, 24k form up and down, the crossbeam 41 of vehicle frame is located at up and down between two couples of angle steel 24e, the 24h, and binding bolt is connected every pair of angle steel respectively.Attaching parts also can be binding bolt (not drawing among the figure), and binding bolt is passed across the crossbeam of affixed fin in left and right guide pipe both sides and vehicle frame and the chain stay radial direction through hole of vehicle frame, also can make the chain stay of the crossbeam of left and right guide pipe and vehicle frame and vehicle frame affixed.As Fig. 1, Fig. 2, Fig. 5, Fig. 6, shown in Figure 7, on left and right guide pipe 13,5 left outer, right pedal roller 15,9, be fixed with left and right turning drag hook 14,11 respectively, between the left and right guide pipe 13,5 pulley 26 is being installed below the crossbeam of vehicle frame, steel rope 27 its two ends of this rope race of process are connected with left and right turning drag hook 14,11 respectively.Above-mentioned pulley 26 is installed in to be located on the substrate 29 that is fixed together with left and right guide pipe between the left and right guide pipe, the pulley endoporus is equipped with the antifriction-bearing box 30 that cooperates with it, binding bolt 25 cooperates with antifriction-bearing box 30, its termination is affixed by nut 28 and substrate 29, steel rope breaks away from grooving when preventing to move backward, and is provided with an arc cover 31 on pulley top.As Fig. 8, shown in Figure 9, left and right rack- plate 17,10 with contacted each side of the track of left and right guide pipe on have respectively the antifriction-bearing box 32,33,34,35 and 32 that reduces force of sliding friction ', 33 ', 34 ', 35 ', the periphery of described each antifriction-bearing box contacts with the track inwall of guide pipe.Be located at left and right rack-plate topmost face and bottom two groups of antifriction-bearing boxs 32,32 of face ' and 35,35 ' in, one group of antifriction-bearing box, 32,32 ' when mounted best axle center deflections of its upper surface are away from the direction of two rack-plates, and one group of antifriction-bearing box, 35,35 ' when mounted best axle center deflections of its lower surface are near the direction of two rack-plates.Can offset left and right guide pipe like this because the heeling error that the motion of rack-plate brings.If above-mentioned antifriction-bearing box is not set, also can inlay the less High molecular material of friction coefficient between guide pipe and the rack-plate, also can directly lubricate by apply lubrication oil.In the utility model when work,, left and right two rack- plates 17 and 10 are done the synchronous crank motion of alternatively up and down with the effect of people's bipod in track separately, and it alternately is along the left and right slip realization of pulley 26 synchronously by steel rope 27.When right rack-plate 10 passes in right rack-plate by vertex to lower slider because of the people acts on power on the pedal, it can drive right ratchet-gear wheel 23 rotations simultaneously, thereby the fixing sprocket wheel 6 that drives on the right spindle nose cap 7 rotates, then drive chain 2 ' make sprocket wheel 1a, rear wheel 1 rotation on chain sprocket 3, the rear wheel, three-wheel vehicle is advanced.When right rack-plate 10 slides to nadir,, and right rack-plate stopped it is stopped because the lower port of guide pipe seals.At this moment, left rack-plate 17 upwards slides into vertex by the pulling of steel rope, and left foot is firmly down pedaled left foot pedal 16 then, and left rack-plate 17 is to lower slider, and by horizontal reset on the right rack-plate 10 of steel rope 27 drives, right crus of diaphragm is not exerted oneself simultaneously.Left side rack-plate 17 drives left ratchet-gear wheel 21 rotations, then drive with the affixed axis 18 of left spindle nose cap 19 and rotate, and then drive sprocket wheel 6 rotations of being fixed on the right spindle nose cap, and rotate by the sprocket wheel 1a on chain 2 ' drive chain sprocket 3, the rear wheel, rear wheel 1, three-wheel vehicle is advanced.
