Abstract
The utility model relates to a multipurpose four-wheel double-driven manpower cycle. The existing three-wheel is changed into a double-driven double-braking steering system with a steering wheel; the utility model overcomes the defects of the three-wheel manpower cycle needs great strength and is not easy to drive; the stationarity is poor; the external shape is fusty without the fresh feeling; the braking is inefficacious, etc. The utility model save the labor and the driving force is increased, compared with the three-wheel cycle, so the climbing and the loading capacity are increased; the speed and the efficiency are largely enhanced; the multipurpose four-wheel double-driven manpower cycle can be pedalled and started synchronously or asynchronously; the brake capacity is strong; use is safe; the utility model has wide practicability and has stronger enjoyment, and the use is very wide.
Description
The utility model belongs to Machine Manufacturing Technology, relates to a kind of improvement of rickshaw structure.
Existing manual tricycle has three acting point.When being in static state, have advantages of higher stability, when running state, acting point becomes two sometimes, and occurs unstable.Gently then cause the unstable wigwag motion of the car weight heart, when running into Uneven road or sharply turning, owing to the inhomogeneous centre-of gravity shift that makes whole car of the suffered pressure of two rear wheels, steerman should be controlled turning to of car, the rotation handlebar that does not stop is again adjusted the center of gravity of car, drives and also can cause overturning when unskilled.Outside inferior, the available man-power three-wheel vehicle is driven the narrow discomfort of seat, and the time of driving, long slightly very susceptible was to tired.Steerman will overcome car deadweight and these two gravity sums of load-carrying at full load, for the 2-3 of human body doubly, also be not less than 1.5 times during zero load, and the application of force direction of stretcher and direction of traffic are inconsistent etc., make single driving extremely require great effort.Also have the external form that does not become for many years, can not adapt to the progress and the development of society.
The purpose of this utility model just is to design the two driving rickshaws of a kind of four-wheel, to solve the above-mentioned problem that exists.
Feature of the present utility model is, the manual tricycle front-wheel is changed into two, make acting point be increased to four, the application force of skew about the car weight heart to front-wheel decomposed on two wheels, four-wheeled acting point under steam is less than three never, improve stationarity greatly, overcome the shortcoming of difficult driving simultaneously; Secondly, the driving of the list of existing three-wheel vehicle is changed into two the driving, increased propulsive effort; Driving the wide thin-skinned seat that seat changes the band backrest into, improve the comfort level of seat simultaneously, reduced the fatigue of steerman, and take to reduce and after move the position of seat, change the application of force direction of stretcher, the measures such as conformability of maintenance and garage's direction have reached the labour-saving purpose; Four-wheel is two to drive many actuating speed and inertia with rickshaw all increase, has also taked to change single brake here and has been the mechanism of dual brake car, has improved the safety braking performance of rickshaw.
Accompanying drawing 1 is the two structural representations that drive many with rickshaw of the designed four-wheel of the utility model, the steering swivel system structural representation that Fig. 2 drives many with rickshaw for designed four-wheel is two.Fig. 3 drives many with rickshaw external form example schematic for designed four-wheel is two.Four wheels 4,8 before and after the rickshaw of four wheel drive shown in the figure is with bearing circle bonded assembly steering swivel system; With the drive system that drives pedal 6 bonded assembly chains 7, driving flywheel 9, two cover stretchers, chain and the big small flywheel of left and right sides parallel arranged and the parallel lever connection of two covers of brake handle 3 bonded assemblys brake wheel 10 and brake drive are arranged, and copilot handrail 2 arranged, steering swivel system of the present utility model includes bearing circle 1, direction lever 11, gear 12, tooth bar 13 and turn to swivel arm 14, drive front-wheel steering axle 15, by front-wheel steer connecting arm 16, by the rotation direction of front-wheel steering connecting rod 17 tracking left and right sides front-wheels.Owing to ball bearing fit rotation direction system is arranged, turns to flexibly so reach.
5 is the chassis frame among the figure.As can be seen from Figure, the front-wheel that is increased in the utility model, drive system, steering swivel system, brake gear, copilot handrail, operator's saddle backrest and various railway carriage, all belonging to so that technology to be arranged, is that the professional and technical personnel can both finish, thereby need not to do more explanation again.
According to the development and the progress of society, people increase to the requirement and the enjoing ability of rickshaw, when pursuing the rickshaw practicality, also further pursue its appearance packaging effect.The design plan of four wheel drive rickshaw has just embodied these characteristics, created and on its concrete overall structure, satisfied in people's first requirement, also satisfy second world that requires as far as possible, can change the leeway of putting various appearance characters and carrying out beautifying and decorating as required.As repack roadlice type, classic car type etc. into.
The utility model implementation result is remarkable: 1. it is easy to drive than the more steady safety of three-wheel vehicle; 2. two drivings can be synchronously or asynchronous starting, and it is quick and labour-saving to start.Double-driving force almost is twice than three-wheel vehicle, so climbing and load carrying ability also approximately double, road speed is also accelerated a lot.Have days off by turns because of being convenient to steerman again, so need not intermediate stop, can prolong the distance of travelling continuously, this can raise the efficiency and benefit; 3. because dual brake bassinet structure brake equipment is set, the brake safe effect greatly improves; 4. operator's saddle is the chair structure, and its seat is free from worry comfortable, is beneficial to outside driver's the fatigue, also can widen the purposes of car simultaneously; Cheap beautiful appearance, practical function is outstanding.If railway carriage is reequiped a little, can make purposes such as mini engineering rolling cart, luxury travel car, dog wagon or mobile commodity mobile store.
Claims (5)
