Background technology
In the present automobile suspension arrangement, torsion bar spring generally is installed on the front-end equipment of automobile, and the forward and backward damping of automobile is with all being independently between the elasticity original paper; Have no contact each other, when like this will be at the direction of vibration of automobile front and rear wheel opposite, the impact that automobile receives can strengthen; The fluctuation that falls after rising before vehicle body can 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 receive certain torsion; Cause the comfort level taken to reduce, and problem such as elastic element is fragile, the Frame and Body skeleton is yielding.For addressing the above problem, the patent of invention in Intellectual Property in China office on July 30th, 2008 disclosed " torsion bar type automobile suspension arrangement " by name, number of patent application is 200810074135.7.This patent application is that forward and backward two torsion bar spring in automobile the same side are linked to each other each other, and links to each other with vehicle frame through registration device, can effectively improve in the vehicle traveling process; Vibration situation on uneven road surface; Vehicle frame and body framwork can not receive torsion simultaneously, prolong the vehicle operation life-span, but because complex structure; The enforcement difficulty is big, has restricted its enforcement.
Summary of the invention
The object of the invention overcomes the defective that existing automobile suspension arrangement exists; Providing a kind of connects the damping spring in the forward and backward shock absorption device of automobile; Make the forward and backward damping spring of automobile set up certain response relation, to reduce the automobile vibrations in the process of moving and the automobile suspension arrangement of raising ride quality.
Technical scheme of the present invention is: a kind of automobile suspension arrangement; Comprise the preceding damping spring and back decoupling rod spring that are installed on the automobile homonymy front and rear suspension; The end and the forward mounting that it is characterized in that above-mentioned preceding damping spring are fixedly linked, and the other end and crank are fixedly linked, and crank is hinged through an end of connecting device and fork; Fork is rotatable to be fixed on the vehicle frame, and the other end of fork is fixedly linked through an end of connecting device and above-mentioned back damping spring.
Above-mentioned fork and vehicle frame between rotatable fixedly be to be fixedly linked by an end and fork middle part, the torsion bar spring composition that resets that the other end and vehicle frame are fixedly linked.
Damping spring is a torsion bar spring with back decoupling rod spring before above-mentioned, and the two ends of fork link to each other with the crank that is fixedly connected with forward and backward torsion bar spring through connecting device respectively.
Damping spring is a torsion bar spring before above-mentioned, and back decoupling rod spring is a vibration damper steel plate, and an end of fork links to each other with the crank that is fixedly connected with preceding torsion bar spring through connecting device, and the other end of fork links to each other with the hanger of vibration damper steel plate through connecting pin.
Connecting device between above-mentioned crank and the fork comprises connecting rod I, connecting rod II and connecting rod III; One end and the crank of connecting rod I are hinged; One end of the other end and connecting rod II is hinged, and an end of the other end of connecting rod II and connecting rod III is hinged, and an end of the other end of connecting rod III and fork is hinged.
Connecting device between above-mentioned crank and the fork is made up of the oscillating bearing that is installed in crank and fork two ends, and two oscillating bearings at fork two ends are fixedly linked with the oscillating bearing that is installed on the crank respectively through pipe link.
Above-mentioned fork and be fixedly connected with before connecting device between the crank of torsion bar spring comprise connecting rod I, connecting rod II and connecting rod III; One end and the crank of connecting rod I are hinged; One end of the other end and connecting rod II is hinged; One end of the other end of connecting rod II and connecting rod III is hinged, and an end of the other end of connecting rod III and fork is hinged.
Above-mentioned fork and be fixedly connected with before connecting device between the crank of torsion bar spring; Oscillating bearing by being installed on the above-mentioned crank is formed with being installed in the oscillating bearing of cooresponding fork one end of above-mentioned oscillating bearing, and above-mentioned two oscillating bearings are fixedly linked through pipe link.
The present invention is with being provided with bindiny mechanism between the forward and backward damping spring of homonymy; Make between the forward and backward damping spring of homonymy and can produce interlock; And have characteristics rational in infrastructure, good damping effect, can effectively reduce the vibration in the vehicle traveling process, improve ride quality.
When Uneven road, when vehicle front receives impact upwards, front-wheel stressed passed to preceding torsion bar spring through the irs control arm that links to each other with front-wheel; The torsion bar spring tension distortion through the connecting rod mechanism of being made up of a plurality of connecting rods, is passed to fork with torsion before this moment; Fork is rotated; Thereby damping spring rotates or moves up and down behind the driving automobile, and automobile rear can be moved with the front portion is equidirectional, thereby can offset the amplitude of automobile bodies 1/2.Same when automobile back wheel receives the impact that makes progress, the front-wheel of automobile under the drive of this device, corresponding moving up or down, thus can offset the amplitude of automobile bodies 1/2.Direction of vibration current, trailing wheel is opposite, amplitude is identical, and forward and backward damping spring torsional deflection is zero, and the vibration of whole vehicle body approaches zero, and at this moment, the effectiveness in vibration suppression of suspension gear of the present invention is best, and automobile can keep horizontal motoring condition.When four wheels during not on same plane; Because the opposition of forward and backward damping spring makes front and rear wheel receive identical power, the wheel at diagonal angle also just receives identical power; So this moment, vehicle frame and body framwork can not receive torsion, prolonged the vehicle operation life-span.
