In the device, front and back torsion bar springs on the same side are mutually connected through a pair of meshed gears and a planar linkage mechanism; a linkage relation is established between the front and back torsion bar springs on the same side, so that the vibration condition of the automobile on uneven roads in the running process can be effectively improved, a frame and a body skeleton cannot be subjected to torsion, and the service life of the automobile is prolonged. The device has the characteristics of reasonable structure, good damping effect and the like.
Description
Technical field
The present invention relates to a kind of suspension gear of automobile, particularly a kind of automobile suspension arrangement of front and back belt torsion bar.
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 torsion bar spring in the forward and backward shock absorption device of automobile; The torsion of the forward and backward torsion bar spring of automobile can be transmitted each other, 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 of front and back belt torsion bar; Comprise the forward and backward torsion bar spring that is installed in the forward and backward suspension of automobile, link to each other through connecting device between the forward and backward torsion bar spring of automobile homonymy that an end of torsion bar spring links to each other with the forward mounting of automobile before it is characterized in that; The other end is installed with preceding torsion bar gear; One end of back torsion bar spring links to each other with the back suspension of automobile, and the other end is fixedly connected on the connecting rod I, and the connecting rod I links to each other with an end of connecting rod II through hinge; The other end of connecting rod II links to each other with an end of connecting rod III through hinge; One end of the other end of connecting rod III and force transmission shaft is fixedly linked, and the other end of force transmission shaft is installed with the power transmission gear, and power transmission gear and preceding torsion bar gear are meshing with each other.
A kind of automobile suspension arrangement of front and back belt torsion bar; Comprise the forward and backward torsion bar spring that is installed in the forward and backward suspension of automobile, link to each other through connecting device between the forward and backward torsion bar spring of automobile homonymy, it is characterized in that an end of the back torsion bar spring of automobile links to each other with the back suspension of automobile; The other end is installed with back torsion bar gear; One end of preceding torsion bar spring links to each other with the forward mounting of automobile, and the other end and connecting rod I are fixedly linked, and the connecting rod I links to each other with an end of connecting rod II through hinge; The other end of connecting rod II links to each other with an end of connecting rod III through hinge; One end of the other end of connecting rod III and force transmission shaft is fixedly linked, and the other end of force transmission shaft is installed with the power transmission gear, and the power transmission gear is meshing with each other with back torsion bar gear.
One end of the torsion bar spring that resets is captiveed joint with vehicle frame, and the other end of the torsion bar spring that resets and connecting rod III are fixedly linked, the torsion bar spring that resets and the coaxial both sides that are distributed in the connecting rod III of force transmission shaft that are fixedly mounted on the connecting rod III.
One end of the torsion bar spring that resets is captiveed joint with vehicle frame, and the other end of the torsion bar spring that resets and force transmission shaft relative fixed are installed on the power transmission gear.
Above-mentioned connecting rod III and connecting rod I are " recessed " shape, and its opening position is connected through bearing pin with the two ends of connecting rod II respectively, and the other end and the force transmission shaft of connecting rod III are fixedly linked, and the other end of connecting rod I is fixedly linked with the back torsion bar spring.
Suspension gear of the present invention; Adopt a pair of pitch wheel and planar linkage mechanism, the forward and backward torsion bar spring of automobile homonymy is interconnected, make between the forward and backward torsion bar spring of homonymy and set up interaction relation; Can effectively improve in the vehicle traveling process vibration situation on uneven road surface.When receiving power upwards suddenly like front-wheel; Under the effect of front damping device, the compartment moves up, torsion bar spring tension distortion before this moment; Through intermeshing a pair of gear and planar linkage mechanism the torsion of preceding torsion bar spring is passed to the back torsion bar spring rapidly; Make back torsion bar spring turn-back distortion, move downward, make also upward movement of rear portion, compartment thereby drive the irs control arm that links to each other with the back torsion bar spring; So just but actv. solves present automobile when jolting road traveling, the problem that the compartment pitches.Through experiment, this device approximately can reduce the amplitude in compartment 1/2, has improved the damping property of automobile.
If front-wheel receives downwards or trailing wheel when receiving power up or down, it is identical that the transmittance process of power and front-wheel receive the power that makes progress, and through the effect of front and back torsion bar spring, can make automobile bodies reach the effect of buffering, approximately can offset 1/2 amplitude.Direction of vibration current, trailing wheel is opposite, amplitude is identical, and forward and backward torsion bar spring tension is deformed into 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 torsion bar 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, had prolonged the vehicle operation life-span.
In sum, this device has rational in infrastructure, characteristics such as good damping effect.
