Abstract

The utility model which relates to a rickshaw and which is of the type of the four-wheeled bus is provided with a traversing mechanism controlling the direction of the two front wheels. The back wheels are provided with a reverse gear and a forward speed gear which is arranged in the inside of the back wheel head and which is driven by pedals, while the reverse gear is arranged in the outside of the back wheel head and is reversely driven by the hand. The utility model has reasonable design adopting four wheels, and is driven by the back two wheels and can be stamped by a single foot or by the two feet at the same time with little force and fast speed, and the utility model has both the forward speed gear and the reverse gear, making the reverse convenient and no need of pushing the rickshaw with getting off, beneficial to reducing or avoiding the obstructing traffic and the traffic accident, and is an ideal vehicle for old people.

Description

A kind of rickshaw

Technical field: the utility model relates to a kind of rickshaw.

Background technology: the rickshaw of prior art mainly contains bicycle and three-wheel vehicle.Though it is less that bicycle accounts for the road surface, also more convenient flexible, need higher technology by bike.Particularly more at present vehicle, pedestrian, under the relatively more crowded situation in road surface, the slow the elderly of action reflection rides usefulness, is easy to have an accident.And three-wheel vehicle generally all is single foot-operated moving, and effort is big, and speed is slow.And have only D Drive, the implementation of can only getting off when falling back, very inconvenient, down to the phenomenon that often occurs blocking the traffic.

Summary of the invention: the purpose of this utility model provides a kind of later-model rickshaw, thereby overcomes the existing above-mentioned drawback of prior art rickshaw.The purpose of this utility model is realized by following scheme: it has vehicle frame, and its main points are to be the four-wheel car formula that the front portion is provided with the direction machine, controls two front-wheels guiding; Trailing wheel is established D Drive and reverse gear, D Drive adopts pedal drive, flywheel is established in inboard at two rear wheel rotation heads, and realize engagement with the dog of wheel ratchet of a side and flywheel side, the outer of flywheel is provided with three circle grooves, the one circle system of fastening is also twined the before driving slide fastener, and the other end of slide fastener is connected on the pedal that is hinged on the vehicle frame; The one circle system of fastening is also twined the return backguy, and the other end of this backguy is connected with coil spring box on being located at vehicle frame; The shift fork of another circle plant fork type engaging and disengaging gear; Reverse gear is located at the outside of back wheel, and is identical with the D Drive structure, and direction is opposite, and the other end that drives backguy is connected the tail end that is hinged in the hand lever on the vehicle frame, manually falls to drive;

The utility model is reasonable in design, adopts four-wheel and back two-wheel drive mode, both can singly ride and move, and can step simultaneously by both feet again, and is firmly little, the speed piece; Existing D Drive has reverse gear again, and reversing is convenient, and implementations of need not getting off helps reducing and the generation with traffic accident of avoiding blocking the traffic, and is to be particularly suitable for the desirable vehicle that the elderly rides usefulness.

Description of drawings: Fig. 1 is a front view of the present utility model

Fig. 2 is a right elevation of the present utility model

The specific embodiment: accompanying drawing has provided a specific embodiment of the present utility model, and according to Fig. 1, shown in Figure 2, this car is the four-wheel car formula, and 4 is vehicle frames among the figure, and the front portion is provided with direction machine 2, controls two front-wheels, 1 guiding; Trailing wheel 9 is established D Drive and reverse gear, D Drive adopts pedal drive, take turns the inboard of head at two trailing wheels 10 and establish before driving flywheel 11, and realize engagement with the dog of wheel ratchet of a side and flywheel side, the outer of before driving flywheel 11 is provided with three circle grooves, the one circle system of fastening is also twined before driving slide fastener 5, and the other end of before driving slide fastener 5 is connected on the pedal 3 that is hinged on the vehicle frame 4; The one circle system of fastening is also twined return backguy 13, and the other end of this backguy is connected with coil spring box 14 on being located at vehicle frame 4; The shift fork of the fork type engaging and disengaging gear 12 of another circle plant before driving flywheel; Reverse gear is located at the outside of back wheel, and is identical with the D Drive structure, and direction is opposite, and the other end that drives backguy 7 is connected the tail end of the hand lever 6 that is hinged on the vehicle frame 4, manually falls to drive.Stir the handle of the fork type engaging and disengaging gear 12 of before driving flywheel 11, can realize before driving flywheel 11 and back wheel clutch, stir the handle of the fork type engaging and disengaging gear 8 of reverse-drive flywheel 9, can realize reverse-drive flywheel 9 and back wheel clutch.When before driving flywheel 11 combines with back wheel, and reverse-drive flywheel 9 is when back wheel breaks away from, and can treadle 3 to drive to move ahead; When reverse-drive flywheel 9 in the back wheel combination, and before driving flywheel 11 can be moved hand lever 6 reversings when breaking away from back wheel.In addition, when before driving and reverse-drive flywheel all break away from back wheel, can very light implementation, and when before driving and reverse-drive flywheel all combine with back wheel, vehicle can be checked, can not move ahead and to fall back, when particularly parking on the slope, can not slide race voluntarily, safe and reliable.
