Abstract
The utility model provides a double drive front wheel three-wheel vehicle, which is characterized in that the structure is an inverted three-wheel structure. Two front wheels are disposed, and the two front wheels are connected to the steering wheel through the steering mechanism and connected to the engine through the transmission mechanism, the two front wheels are also driving wheels. A rear wheel is positioned at the lower part of the central of the back vehicle. The output shaft of the engine (5) is connected to the telescopic universal transmission shaft (6) through the universal joint and is connected to the front wheels (1). The structure of double drive and steering front wheel-rear wheel in the utility model is an original in the vehicle design, which simplifies the transmission mechanism radically and improves the stability and security of the driving vehicle. The comfortable steering wheel operation is retained. The fully-closed vehicle body is realized. The inner space is spaciousness. The vehicle body can fully adopts the common vehicle structure, which can suite for the development of family popularization in our country and the urban writers.
Description
Technical field
The utility model relates to self-propelled vehicle, particularly relates to the self-propelled vehicle that three-wheel is only arranged.
Background technology
The car of people's driving at present all is a four wheels, technology is quite ripe, but four-wheel car are made complicated, price is higher, also exist the safety hazard that the four-wheel structure is caused, the front-wheel steering of Here it is four-wheeled vehicle has a time difference to rear-axle steering, just trailing wheel can not turn at once during front-wheel steering, because the existence of this time difference, so produce the vehicle rear swing when turning to during four-wheeled vehicle travels, the speed of a motor vehicle is fast more, and amplitude of fluctuation is big more, and this situation has influenced the stability of four-wheeled vehicle.The three-wheel locomotive that many types are also arranged, wherein most three-wheel locomotive has a steering front wheel and two rear drive sprockets that are set parallel to each other, the three-wheel locomotive has to be made simply, cost is low, fuel-efficient, advantages such as convenience, but prior art constructions has some driving performance shortcoming, as side thrust is big when turning to, easily skid when braking and acceleration etc., therefore people are also at the three wheeled motor vehicle of exploring another kind of wheel configuration structure, as Chinese patent application 90215635 " three wheeled motor car ", Chinese patent application 87201409 " three wheeled motor vehicles of two front-wheels " China is application 01119104 " three-wheel vehicle with two steering front wheeles " specially, Chinese patent application 03222691.8 " a kind of self-propelled vehicle " etc.
Summary of the invention
It is a kind of simple and reasonable for structure that the purpose of this utility model is to provide, and volume is little, and is in light weight, low price, reliable, fuel-efficient, three wheeled motor vehicle easily.
The utility model three wheeled motor vehicle comprises vehicle body, wheel, driving engine, it is characterized in that three wheels are down tricycle structure, front-wheel is two, two front-wheels link by steering hardware and bearing circle and link by transmission device and driving engine, two front-wheels be steering wheel be again drive wheel, a trailing wheel is positioned at below, body tail center and is balance wheel, it is flower wheel, owing to save a trailing wheel than general four-wheeled, make the weight saving of car, running resistance reduces, and two preceding steering wheels have dwindled the car turn radius, and the time to turn that has thereupon shortened front and back wheel when turning to is poor, making turns becomes more flexible, steering wheel can also prevent effectively that vehicle ' from turning to the side thrust of generation before two, reduces the amplitude of fluctuation of Ackermann steer angle, makes vehicle ' safety and stable more.
Because two front-wheels are again drive wheels, dynamic property is preferable, engine behind front wheel, and transmission is arranged compact, the transmission shaft before and after not passing through can reduce bodywork height, alleviates car weight, increases vehicle stability, improves the streamline contour of car body.
Driving engine places the front end of vehicle body, and in fact, driving engine can be selected motor cycle engine for use, owing to motor cycle engine is used widely, and technical maturation, so its maintenance is very convenient.Driving engine and preceding two-wheel can adopt universal drive shaft mechanism to connect.
Compared with prior art, the utility model is simple and practical, and low price is safe and reliable, and energy consumption is low, and trailer reversing is convenient and simple, and interior space is spacious relatively.
Description of drawings
Fig. 1 is the utility model front-wheel steering scheme drawing
Fig. 2 is the utility model major part schematic top plan view
Among the figure: 1 is front-wheel, and 2 is trailing wheel, and 3 is vehicle frame main beam, and 4 is bearing circle, 5, be driving engine, and 6 is telescopic universal drive shaft, and 7 is the direction machine, and 8 is the direction pull bar, and 9 are the brake clip, and 10 are the brake video disc, and 11 hold up for the speed change hand, and 12 sail seat for frame, and 13 is universal-joint.
The specific embodiment
Embodiment 1:
Fig. 1 has described steering swivel system of the present utility model, and vehicle steering 4 is by its axostylus axostyle steering machine 7, and direction of passage pull bar 8 drives double front wheel 1 and turns to.
Fig. 2 is the utility model major part birds-eye view, driving engine 5 places the front end of car, place between two front-wheels 1, driving engine 5 adopts 150 type motor cycle enginees, add reversible gear, its output shaft links by universal-joint 13 and telescopic universal drive shaft 6, and join with double front wheel 1, telescopic universal drive shaft 6 is announced as prior art in Chinese patent application 200420104547 " compound type universal drive shaft " specification sheets, it can adapt to double front wheel 1 and turn to the transmission shafts that causes to change to length, guarantees the flexible, reliable of transmission.The speed change hand is held up the 11 speed reduction gearing control speed of a motor vehicle by driving engine 5, and brake pedal may command brake clip 9 is checked brake video disc 10, makes vehicle brake.2 one of flower wheel trailing wheels are placed in the bottom of elastic support, form the inverted triangle topology layout with two front-wheels.Frame is sailed seat 12 and is arranged on the vehicle frame main beam 3.
The structure of two drivings of the utility model and steering front wheel one trailing wheel is created in the automotive designs of prior art, fundamentally simplified transmission device, improve safety, the stability of vehicle ', kept comfortable steering wheel type maneuverability pattern simultaneously again.Driving engine is placed on body structure, be convenient to the cooling and the maintenance of driving engine, simultaneously, can realize totally-enclosedization of vehicle body, the interior of body space is spacious relatively, and vehicle body can adopt vehicle structural commonly used, three to four seats can be set, the demand for development that adapts to China family mass car is fully enjoyed the car sensation with the three-wheel vehicle price, and the roadlice of family expenses is made in suitable city.
