Description

Double-driving dual-purpose tricycle

The utility model relates to a kind of trishaw.

Trishaw can loading, again can be manned, travel than bicycle safe, and be subjected to the elderly and women gradually and welcome.But three-wheel vehicle has only a cover driver train at present, and two people take and can only be driven by a people, and labour intensity is big, and the people that muscle power is relatively poor can't be competent at.

The purpose of this utility model provides the difunctional three-wheel vehicle of the two drivings in a kind of labour-saving.

The purpose of this utility model is to realize as follows: it is provided with two cover pedal drive mechanisms, pedal drive mechanism 6 and rear treadle driver train 7 promptly, preceding pedal drive mechanism 6 is installed in vehicle frame 3 preceding bottoms, vehicle frame 3 bottoms before rear treadle driver train 7 is installed between pedal drive mechanism 6 and the trailing wheel 8, two cover pedal drive mechanisms are made of foot-operated, sprocket wheel, chain and flywheel, the common trailing wheel 8 that drives can two people drive simultaneously, also can people's independent drive.12 are connected with preceding boxboard 15 usefulness hinges 14 at the bottom of the preceding case of railway carriage 9, can open, and 12 have connecting panel 11 at the bottom of the preceding case, with screw 10 be axle mounting in railway carriage 9 both sides, at the bottom of the preceding case 12 and preceding boxboard 15 place railway carriage 9 anterior original positions, promptly become load-carrying vehicle case (Fig. 1); Before below 12 cushion 13 is arranged at the bottom of the case, there is back cushion 16 in preceding boxboard 15 outsides, with 12 turning over 180 ° backward at the bottom of the preceding case, place railway carriage 9 rear portions, preceding boxboard 15 also leans against the back of railway carriage 9 thereupon, promptly becomes seat; The 9 preceding ends of railway carriage and toe lasting also all open wide, and are sitting in and can drive rear treadle driver train 7(Fig. 2 on the cushion 13).The adjusting slotted hole is arranged on the connecting panel 11, can before and after regulate before 12 seats that constitute and the distance of rear treadle driver train 7 at the bottom of the case.

The utility model compares with existing similar technology, and following advantage is arranged;

(1), can loading, can doublely take again, and be provided with child seat, pick child for man and wife both employed are on and off duty.

(2), be provided with two the cover pedal drive mechanisms, can drive simultaneously during double taking, laborsaving, the speed of a motor vehicle is fast, muscle power relatively poor the elderly and women all can drive.

Accompanying drawing is the example that the utility model provides:

Fig. 1: the difunctional three-wheel vehicle of two drivings constitutes loading railway carriage constitution diagram;

Fig. 2: the difunctional three-wheel vehicle of two drivings constitutes for the people takes constitution diagram;

As shown in the figure: 1, front-wheel, 2, handlebar, 3, vehicle frame, 4, vehicle seat, 5, child seat, 6, preceding pedal drive mechanism, 7, rear treadle driver train, 8, trailing wheel, 9, railway carriage, 10, screw, 11, connecting panel, 12, at the bottom of the preceding case, 13, cushion, 14, hinge, 15, preceding boxboard, 16, back cushion.Vehicle frame 3 is to make with steel pipe, and at the bottom of railway carriage 9, the preceding case 12, preceding boxboard 15 usefulness angle steel and sheet steel make, constructional feature has described in detail as above; All the other adopt bicycle and three-wheel vehicle common component to form, and belong to known technology, not quite clear elaboration.
