Abstract
The suspension device for automobile comprises elastic components, a guiding mechanism, and a shock-absorption device. Between the front and the back elastic components which are on same side of automobile is set a connecting mechanism. Each of the two ends of a pull rod is connected respectively to the front and the back elastic component through a triangular lifting-ear hinged with the frame. There is a central support in the middle part of a balancing device, on each of two sides of the central support there is a balancing spring. A balancing brake is fitted by the pull rod which crosses through the holes of the central support, and it can brake simutaneously with the automobile. Advantage: good shock-absorption effect etc..
Description
The present invention relates to the suspension gear of automobile, specifically, is a kind of mechanism that connects automobile homonymy fore suspension and rear suspension elastic element, and this bindiny mechanism is applicable to and connects the vertical elastic elements such as steel spring, coil spring of putting.
The elastic element that uses on modern bus and the truck is of a great variety, performance is different, generally steel spring, coil spring, torsion bar spring, gas spring and rubber spring are arranged than general-duty, any spring no matter, when automobile runs into irregular road surface and beats, can both absorb most of impact energy that wheel is subjected to, the vibration when having reduced driving.But, no matter adopt dependent suspension, still adopt the elastic element of independent suspension, the effect of its fore suspension and rear suspension elastic element all is independently, be independent of each other mutually, in the vehicle ' process, the vibration of front and back wheel is without any contact, the impact meeting that vehicle is subjected to if the direction of vibration of front and back wheel is opposite is bigger, the motion that falls after before vehicle body will produce, in addition, when four wheels during not on same plane or have a pair of horn ring stressed when big, then the Frame and Body skeleton will be subjected to certain torsion, therefore, adopt the suspension gear of this structure, elastic element is fragile, the Frame and Body skeleton also damages easily, simultaneously, also can cause the damage of goods or make the occupant feel uncomfortable.
The suspension gear that the purpose of this invention is to provide a kind of automobile, it makes automobile fore suspension and rear suspension elastic element have the good whole elastic performance, and effectiveness in vibration suppression is obvious.
The objective of the invention is to be achieved through the following technical solutions: adopting the vertical automobile homonymy of putting steel spring and coil spring as elastic element, before, set up a bindiny mechanism between the back elastic element, it comprises pull bar, balance position device and balanced brake, the two ends of pull bar respectively by with vehicle frame pivotally attached triangle hanger and before, back elastic element is connected, the balance position device comprises center frame and balance spring, before center frame places, the middle body of back elastic element, the top and the vehicle frame of center frame are connected, the bottom is provided with boss, boss is provided with cross through hole, pull bar passes through hole, and can in through hole, move, the front, bottom of center frame has rectangular opening, balanced brake is installed in the rectangular opening, balance spring has two, the both sides of center frame are placed in, balanced brake adopts the butterfly drg, the pull bar that passes through hole is sandwiched between two Friction disks of balanced brake, the oil pipe of balanced brake and automobile brake oil pipe are connected, lever connection simultaneously during car brakeing, thus bindiny mechanism is braked.
The forward and backward elastic element of automotive suspension adopts following several selection schemes, all can realize purpose of the present invention:
Forward and backward elastic element all adopts steel spring;
Forward and backward elastic element all adopts coil spring;
Preceding elastic element adopts coil spring, and back elastic element adopts steel spring.
Suspension gear of the present invention, the set betwixt bindiny mechanism of the forward and backward elastic element of homonymy acts on down, improved the vibration situation on uneven road surface in the vehicle traveling process, when if front-wheel or trailing wheel are subjected to up or down power, rotate up or down simultaneously around fixing round end with two triangle hangers of elastic element pivotally attached, the pull bar two ends all are subjected to pulling force or thrust, thereby applied a subsidiary load opposite with ground force to front and rear wheel, approximately can offset 1/2 amplitude, reduce the horizontal vibration of vehicle body.If the direction of vibration of front and rear wheel is opposite, amplitude is identical, approach zero by the vibration of whole vehicle body, at this moment, the effectiveness in vibration suppression of suspension gear of the present invention is best, and automobile can still keep horizontal motoring condition.When four wheels during not on same plane, because the effect of triangle hanger and pull bar makes front and rear wheel be subjected to identical power, the wheel at diagonal angle also just is subjected to identical power, thus this moment vehicle frame and body framwork can not be subjected to torsion, prolong the vehicle operation life-span.
