Abstract
This invention relates to a rhombic suspending and steering mechanism. Its suspending part consists of a front-rear suspending and a middle-suspending unit. The front-rear suspending unit consists of two longitudinal swing arms and torsion springs. The both longitudinal swing arms are respectively connected with front and rear wheel at their both ends, and connected with chassis via a torsion spring. The middle suspending unit consists of two lateral swing arms and torsion springs. The both lateral swing arms are respectively connected with one of side wheels at one of their ends, and connected with the chassis via a torsion spring. The steering part consists of a steering frame and a swing lever. The steering frame is connected with the front and rear wheels, and the swing lever, of which front portion is equipped with a large gear wheel engaged with a small gear wheel that is connected with the steering wheel. The front wheel and rear wheel are located on a lnogitudinal line. The suspending mechanism occupies space less and can turn in a short radius. It has a bumping effect due to its front suspending unit when a collision occurs.
Description
Technical field:
The present invention relates to the Vehicle Engineering field, be specifically related to supporting, the steering hardware on a kind of quasi-rhombus vehicle chassis.
Background technology:
At present, automobile is mainly two kinds of three wheeled motor vehicle and four-wheel automobiles by the classification of the layout of wheel, and 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, and the automobile of this structure improves through years of development, 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.The Decree of Patent Office of China a kind of quasi-rhombic automobile, (application number: 00128286.7), its four wheels are by each one of front and back, middle two layouts that assume diamond in shape, four-wheel automobile has bigger variation in structure and moulding relatively, but the whole connection mode that its wheel is traditional with remaining employing being connected of vehicle frame, the front and rear wheel employing fork structure that connects to ground, though chassis take up space is less than four-wheel automobile, but still occupy certain space, adopt the type of drive of rack-and-gear simultaneously in the steering hardware, be not easy to the layout of other member.
Summary of the invention:
Technical matters to be solved by this invention is the defective that overcomes present prior art, and it is little to provide a kind of chassis to take up space, and turn radius is little, compact conformation, and flexible operation, in light weight, quasi-rhombus vehicle supporting, steering hardware that the safety guard-safeguard performance is higher.
Technical matters of the present invention is to solve by following technical scheme.It is characterized in that wheel supporting mechanism is made up of forward and backward sprung parts and intermediate suspension member, described forward and backward sprung parts comprises two trailing arms and torsion bar spring, wherein two trailing arms, one end links to each other with trailing wheel with front-wheel separately, 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, and transversal swinging arm links to each other with vehicle frame by torsion bar spring; 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.
As a further improvement on the present invention, two trailing arms are hinged by stub and front-wheel and trailing wheel in its sprung parts, and this stub places front-wheel and rear axis position, and are vertical with the main shaft that front-wheel and trailing wheel are installed, between vehicle frame and trailing arm and transversal swinging arm, damper is housed also.
The present invention has following technique effect:
1) four wheels of the present invention layout that assumes diamond in shape, each wheel support adopts suspension frame structure to link to each other with vehicle frame respectively, each member of vehicle frame is arranged at grade, simple in structure, the chassis takes up space little, space that can corresponding increase interior of body, simultaneously production technology is simplified greatly, the corresponding reduction of cost, weight saving also can be convenient to the control of quality bills of materials;
2) because front, chassis sprung parts is positioned at chaufeur or front occupant position, when automobile generation head-on crash, front suspension can contact with the collision thing earlier, can play buffer action, and during similar vehicle collision, vehicle body can deflect, thereby alleviates the severe degree of collision, and its collision safety performance can obtain improvement in essence; 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) steering hardware drives bogie truck by fork and large and small gear meshing and moves, its structure design compactness, and front and rear wheel is positioned on same vertical straight line, and realizes the interlock of steering hardware by flexible wire ropes, flexible operation, turn radius is little;
4) 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 the glancing impact motor turning.
