Background technology:

Developing of automobile industry has experienced by simple to complicated, performance becomes better and approaching perfection day by day, the process that safety, traveling comfort are more and more higher, but up to now, automobile is nothing but two kinds of three wheeled motor vehicle and four-wheel automobiles by the classification of the layout of wheel, wherein three wheeled motor vehicle is to load onto single-wheel at front axle, adorns left and right the wheel on the rear axle; And four-wheel automobile is on forward and backward axle left and right the wheel to be housed respectively, and the driving engine of automobile adopts preposition and rearmounted dual mode.The main vehicle of automobile is the four-wheel automobile of engine behind front wheel at present, and the process years of development of this structure is improved, and the continuation of its safety and operation stability improves has not had great leeway, because each wheel of front, rear, left and right be arranged in parallel, therefore, its turn radius is relatively large, and operation neither be very flexible, simultaneously, its chassis is the structure of a spatial destribution, has the space and occupies greatly the defective that structural behaviour is bad, be unfavorable for alleviating complete vehicle weight, improve service life.Along with the continuous progress of auto-industry, comprehensive vehicle performance especially safety performance requires to improve day by day, and its outward appearance is also constantly being improved, the automobile of exploitation new ideas structure and moulding, and the new varieties that increase automobile have become developing of automobile industry trend.

The utility model content:

Technical problem to be solved in the utility model is the defective that overcomes present prior art, provides a kind of turn radius little, and flexible operation is in light weight, and institute takes up space little, the safety guard-safeguard performance is higher and so on rhombus chassis.

Technical matters of the present utility model is to solve by following technical scheme.It comprises vehicle frame, is four wheels that the class rhombus distributes, described front-wheel links to each other with steering hardware with trailing wheel, revolver links to each other with driver train with right wheel, it is characterized in that front-wheel links to each other with vehicle frame by forward and backward sprung parts respectively with trailing wheel, and revolver links to each other with vehicle frame by middle suspension with right wheel.Described forward and backward sprung parts comprises two trailing arms and torsion bar spring, wherein two trailing arms, one end is hinged by stub and front-wheel and trailing wheel separately, this stub places front-wheel and trailing wheel centre plane, vertical with the main shaft that front-wheel and trailing wheel are installed, the other end links to each other with vehicle frame by torsion bar spring, suspension comprises two transversal swinging arms and torsion bar spring in the middle of described, revolver links to each other with transversal swinging arm separately with right wheel, transversal swinging arm links to each other with vehicle frame by torsion bar spring, between vehicle frame and trailing arm and transversal swinging arm damper is housed also.Described steering hardware comprises bogie truck, fork, and described bogie truck links to each other with trailing wheel with front-wheel respectively, links to each other with fork by steel rope simultaneously, and the big gear wheel that is meshed with miniature gears wherein is housed on the front roll bar, and miniature gears and bearing circle join.Described driver train comprises driving engine, transmission shaft, diff and two-semiaxle, and driving engine places the vehicle frame rear portion, links to each other with diff by transmission shaft, and two-semiaxle one end joins with revolver and right wheel respectively, and the other end links to each other with diff.

The utlity model has following technique effect:

1) the utility model with four wheels of automobile by each one of front and back, middle two layouts that assume diamond in shape, and vehicle frame also assumes diamond in shape, and each wheel adopts suspension frame structure to link to each other with vehicle frame respectively, can make the chassis form a plane, simple in structure, it is little to take up space, and space that can corresponding increase interior of body can make production technology simplify greatly simultaneously, the corresponding reduction of cost, weight saving, fuel-efficient, also can be convenient to the control of quality bills of materials.

2) because the front, chassis is a sprung parts, when automobile generation head-on crash, can contact with the collision thing earlier, can play buffer action, simultaneously because the diamond features of vehicle frame, during similar vehicle collision, vehicle body can deflect, thereby alleviate the severe degree of collision, its collision safety performance is compared the improvement that can obtain in essence with common four-wheel automobile; Simultaneously, because the front and rear wheel sprung parts is positioned at the vehicle frame side, when automobile generation offset collision, can be effectively crashproof under the condition that does not increase special structure, the safety that has further improved auto against.

3) because there are left and right two wheels the centre, when generation side collision and automobile rolled, automobile had bigger improvement to occupant's protective value, and the possibility of rolling is littler;

4) the chassis layout that assumes diamond in shape, its front and rear wheel and connect by linkage steering mechanism on same vertical straight line, and turn radius is little, flexible operation;

5) power that acts on the vehicle frame of forward and backward sprung parts is close to center, elevation profile, chassis, has reduced greatly under equal conditions, can reduce the rigidity of vehicle frame and vehicle body because the ground injustice causes the moment of torsion to vehicle frame and vehicle body, and further expendable weight reduces oil consumption.

6) the front and rear wheel stub is positioned at tire elevation profile centre plane, when running into the road surface and be uneven, helps preventing the shake of front and rear wheel pendulum, and can prevent that the glancing impact vehicle body from turning to.
