Description

Tricycle

The utility model relates to a kind of manual tricycle.

Existing three-wheel vehicle is to pedal by the pedal car, drives the trailing wheel rotation to drive sprocket wheel and chain.Its weak point is that the speed of a motor vehicle is slower.

The purpose of this utility model is to overcome above-mentioned weak point of the prior art and a kind of three-wheel vehicle is provided.

The purpose of this utility model can reach by following measure: the utility model is made up of pedal, treadle, hand, handle, four inflators, storage tank, promotion cylinder, connecting rod, piston, distributing ring, spring, jacking block, front forked frame, sleeve pipe, bearing, steel cable, crutches axle, vehicle frame, front-wheel, trailing wheel, seat and supports.There is pedal left and right treadle rear end, and front end cuts with scissors the both ends that are loaded on front forked frame respectively, and front forked frame passes the sleeve pipe that is welded on the vehicle frame, and fork props up on front wheel spindle, and bearing is arranged in the sleeve pipe.The treadle front end is being fixed pressure rod, and pressure rod is loaded in the inflator, and the inflator hinge is loaded on the vehicle frame.Hand hinge is loaded on the support of vehicle frame, cuts with scissors the dress pressure rod at hand chord position respectively in support position up and down, and pressure rod is loaded in the inflator, and the inflator hinge is loaded on the vehicle frame.Left and right pedal of left and right bipod trampling and both hands shake hand, respectively the air in four inflators is compressed, pressurized air enters in the storage tank, pass through valve mechanism, make pressurized air enter left and right promotion cylinder successively, rotate together with trailing wheel thereby promote connecting rod drive crank shaft, advance forward to drive three-wheel vehicle.

The drawing of accompanying drawing is described as follows:

Fig. 1 is a front elevation of the present utility model.

Fig. 2 is top view of the present utility model (seat does not draw) figure.

Fig. 3 is the A-A cutaway view of Fig. 2, amplifies to illustrate distribution (air inlet) mechanism that promotes cylinder.

Fig. 4 is the scheme drawing of the exhaust gear of promotion cylinder.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing: the utility model comprises: a left side, right-hand tread plate 1 and 2, a left side,

right inflator

3 and 4, storage tank 5, front forked frame 6, steel cable sleeve 7, hand 8, sleeve pipe 9, on, following pressure rod 10 and 11, on, following inflator 12 and 13, a left side, the right cylinder 16 and 17 that promotes, crutches axle 18, a left side, right treadle 19 and 20, vehicle frame 21, a left side, right connecting

rod

22 and 23, before, trailing

wheel

24 and 25, a left side, right steel cable 26 and 27, piston 28, distributing ring 29, jacking block 41, spring 30, accumulation chamber 44, seat 31, support 32, a left side,

right pressure rod

33 and 34 and handle 35.There are left and right pedal 1 and 2 in left and right treadle 19 and 20 rear end, and front end cuts with scissors the both ends that are loaded on front forked frame 6 respectively, and front forked frame passes the sleeve pipe 9 that is welded on the vehicle frame 21, and fork has bearing 38 on front-wheel 24 and wheel shaft 39 in the sleeve pipe.The front end of left and right treadle is being fixed left and

right pressure rod

33 and 34, and pressure rod is loaded in left and right inflator 3 and 4.Hand 8 hinge is loaded on the support 32 of vehicle frame, cut with scissors respectively at hand 8 position up and down that is positioned at support 32 load onto, pressure rod 10 and 11 down, pressure rod 10 and 11 is loaded in upper and lower inflator 12 and 13, upper and lower inflator hinge is loaded on the vehicle frame 21.The structure of above-mentioned left and right, upper and lower four inflators (comprising the inlet and outlet structure), action and function are identical with the hand air pump that existing bicycle is used always.

What promote cylinder joins (advancing) mechanism of qi structure referring to Fig. 3, promoting cylinder 17 welds mutually with the accumulation chamber that stretches into and be fixed on the storage tank 5, jacking block 41, spring 30 and distributing ring 29 are equipped with in the left end inside of accumulation chamber, process a plurality of (present embodiment is 8) induction opening 36 around the accumulation chamber, connecting rod 23 is articulated in (the pivotally attached schematic relationships of only drawing on the figure) on the piston 28, and jacking block 41 left ends are processing a plurality of air inlet ducts 37 with induction opening 36 cooresponding positions.

Before starting three-wheel vehicle, get on the bus earlier, by foot-operated and hand air in four inflators is compressed, pressurized air enters in the storage tank, treat that the storage tank internal gas pressure reaches certain pressure intensity (present embodiment is 1.5 gauge pressures), can on storage tank, measure by the setting pressure table, also can according to step on shake with force feeling (to inflate in the bicycle with hand inflator feel similar) estimate.Get off then, promote three-wheel vehicle, treat that arbitrary connecting rod supports the left end point (see figure 3) in a left side or the right connecting rod, the piston left end is pushing away jacking block and is overcoming the elastic force of spring 30 and distributing ring 29 is pushed up to right-hand member, be that induction opening 36 is no longer sealed by distributing ring 29, pressurized air in the storage tank enters accumulation chamber immediately, promotes jacking block 44 and piston 28 and drives 15 rotations of turning right together with connecting rod 23.Meanwhile, distributing ring moves right under action of the spring to retaining platform 45 places, induction opening is sealed and stopped air inlet, because the volume of accumulation chamber is enough big, pressurized air expansion working in the accumulation chamber, continue the promotion piston and move to right, and air pressure reduction and few, thereby guarantee that the speed of connecting rod drive crank throw still has enough greatly.Treat that piston moves to the right endpoint (see figure 4), the pressurized air that accumulation chamber and piston left part promote in the cylinder can be passed through a plurality of deflation holes 42 and a plurality of air discharge duct 43 exhaust to atmospheres immediately, when like this, guaranteeing that connecting rod drives return piston stroke in the big vapour lock of a piston left side unlikely appearance in chamber.Turn right 15 when going to right endpoint, turning left 14 goes to left end point, pushes distributing ring open and allows a left side promote the cylinder entrance pressure air that contracts.At this moment, the people just can get on the bus, and is on and on foot-operated and hand, thereby constantly to the storage tank voltage supply air that contracts, three-wheel vehicle just can be ceaselessly to overtake.Along with the quickening of foot-operated and hand frequency, the three-wheel speed of a motor vehicle is constantly accelerated.Practice draws: when firmly and painstaking situation and existing driving a pedicab when close, the speed of a motor vehicle of the present utility model is than higher.

The manipulation of three-wheel vehicle working direction is referring to Fig. 1 and Fig. 2.One end of left side steel cable 26 is fixed in the left end of handle 35, left side steel cable penetrates sleeve 7 reel cage 8 of starting with of going forward side by side, be fixed in the left end of front forked frame 6 after 32 position passes from hand chord position in support, in like manner, one end of right steel cable 27 is fixed in the right-hand member of handle 35, penetrate sleeve and hand, after the same area of left steel cable passes, be fixed in the right-hand member of front forked frame.Sleeve 7 and hand 8 are tubulose part in addition, hand 8 top and handle 35 are fixedly connected, movable hinge 40 is arranged between hand 8 top and the bottom, in the movable hinge bearing is arranged, its structure is identical with function and bicycle front fork, be that handle 35 is rotatable together with hand 8 top, and does not rotate hand 8 bottom.Like this, when needs front-wheel 24 turned round to the left or to the right, handle is deflection to the left or to the right, and left and right steel cable will front forked frame together with front-wheel deflection to the left or to the right by tractive.

The utility model contrast prior art has following advantage: can bring into play simultaneously foot-operated and hand effect, thereby can obtain the higher speed of a motor vehicle.
