Abstract

A quasi-rhombic automobile features that its 4 wheels are arranged in rhombic mode, that is, two steering wheels as respectively installed on front axle and rear axle, and two drive wheels are installed at left and right each end of central axle. Said steering wheels have different turning directions. The engine assemblage is installed at central position of chassis. The car body is in streamline shape. Its advantages are high collision damping performance, small turning radius, light weight, acsthetic appearance, good aerodynamic performance and flexible operation.

Description

Quasi-rhombic automobile

The present invention relates to the automotive engineering field, the quasi-rhombic automobile of specifically a kind of new ideas structure and moulding.

The automobile particularly development of car has experienced structure from simple to complexity, performance becomes better and approaching perfection day by day, the process that safety, level of comfort are more and more higher, but till settled the present, automobile had only three wheeled motor vehicle and four-wheel automobile two classes by the layout classification of wheel, the former front axle dress single-wheel, rear axle is adorned left and right the wheel, on the latter's the forward and backward axle left and right the wheel is housed respectively.Automotive engine also has only preposition and rearmounted two kinds, and the automobile of this traditional design layout has its advantage, and the four-wheel automobile of engine behind front wheel is the main vehicle of car at present.This vehicle is improved through years development, continues raising safety and operation stability and does not also have much leeway.In order to improve vehicle safety performance, improve outward appearance, need the automobile of exploitation new ideas structure and moulding, increase the new varieties of automobile.

Purpose of the present invention is exactly for increasing the kind of new ideas structure and moulding automobile; a kind of quasi-rhombic automobile is provided; its buffering energy-absorbing performance to collision is stronger; safety guard-safeguard performance to the passenger is higher, and turn radius is little, flexible operation; expendable weight; the profile smoothness is attractive in appearance, and aerodynamic performance is good, saves the energy.

The object of the present invention is achieved like this:

A kind of quasi-rhombic automobile comprises body assembly, chassis assembly, engine assembly, electrical equipment assembly, it is characterized in that:

A. the layout that assumes diamond in shape of four wheels in the chassis assembly, forward and backward axle is respectively adorned a wheel, and this two wheel is wheel flutter, the left and right wheel of respectively adorning of axis, and this two wheel is a drive wheel;

B. the steering hardware in the chassis assembly connects the bogie truck of front and rear wheel respectively, and the direction of rotation of this front and rear wheel;

C. engine assembly is installed in the middle part on chassis.

Described chassis frame assumes diamond in shape, and it becomes " worker " font by the vertical frame in former and later two horizontal frames and middle part is affixed, and this forward and backward horizontal frame respectively has the arc overhanging beam;

The structure of the steering hardware in the described chassis assembly is: front and back wheel is connected with bogie truck by shock absorber, bogie truck connects to ground by bearing pin, one articulation steering pull bar is respectively arranged about trailing or leading bogie, the left articulation steering pull bar of forecarriage is connected with the right articulation steering pull bar of trailing truck by flexible wire ropes, the right articulation steering pull bar of forecarriage is connected with the left articulation steering pull bar of trailing truck by flexible wire ropes, flexible wire ropes is fixed with the lever of " L " type, the other end of " L " type lever is connected by slideway with an end of spur rack, spur rack and straight gear engagement, this straight gear is fixed on the axostylus axostyle of bearing circle;

Described engine assembly is installed on the vertical frame in middle part of vehicle frame, this engine assembly is connected left wheel by universal-joint with semiaxis, be connected right wheel with semiaxis by universal-joint, the wheel carrier of this wheel is fixed in left and right swing arm, this two swing arm end in addition respectively is articulated in rotating shaft, the hinged damper that is with spring of this wheel carrier, this damper end in addition are articulated in vehicle frame, and described wheel is arranged in the interval of " worker " glyph framework of vehicle frame.

Swept-out centre symmetrical before and after described vehicle body is is wide, the class rhombus of two terminal circle arcuation.

Front-row seats is towards identical with the automobile working direction in the described vehicle body, and back seat is towards opposite with the automobile working direction.

The present invention has following actively useful effect:

1. the present invention presses each one of front and back, middle two layouts with the four wheels of automobile, the four wheels layout that assumes diamond in shape, and vehicle frame (chassis portion) also assumes diamond in shape, its collision safety performance must obtain improvement in essence than common four-wheel automobile, when being head-on crash, front-wheel at first contacts and is bumped object, play buffer action, owing to the diamond features of vehicle frame, when similar vehicle bumped against, car body can deflect simultaneously, thereby reduce to collide severe degree, because engine assembly is positioned at the middle part, the buffer zone of front and back increases, and helps the protection to the occupant again;

Since the centre have engine assembly and about two tires, when side collision and automobile taking place rolling, automobile improves greatly to occupant's protective value;

3. because back seat when head-on crash towards opposite with the automobile working direction, takes place, back row's seat occupant need not safety strap and air bag for protection, only needs to consider the seat headrest safety measure of anti-occupant's neck injury;

4. vehicle body adopts the airflow design with fine aerodynamic performance, helps reducing air resistance, thereby cuts down the consumption of energy, and also can improve the stability of running at high speed simultaneously;

5. the wheel rhombus is arranged, turn radius is little, flexible operation;

6. interposed structure can be very compact in the engine assembly, is convenient to expendable weight;

7. can be designed to forward and backward left-right symmetric shape, novel structure, good looking appearance.

Now in conjunction with the accompanying drawings:
