Abstract

The invention relates to a vibration damping system with steering automatic balance, belonging to the field of vibration damping and balancing systems of vehicles. A vibration damping mechanism is constituted by three or more than three ordinary vibration dampers, and the vibration dampers constitute a star-shaped (Y-shaped) or triangular (delta-shaped) or star-shaped and triangular combined structure. When an obstacle which is higher than the ground is encountered, the vibration damping which is originally relatively vertical becomes relatively horizontal, a force component of a load, which is decomposed to the horizontal direction is greater, the force component in the vertical direction is smaller, the stroke of vibration damping operation is increased and the rigidity is reduced. Oscillation is further transferred to other vibration damping mechanisms of the same vehicle for absorption and damping. Therefore, the whole vehicle can be almost prevented from jolting along with the unevenness of a pavement. When steering is performed, the pressure on the outer side of a bend is increased, the vibration damping mechanism on the outer side is compressed, the vertical vibration damper in the vibration damping mechanism on the inner side is pulled to be in the trend of getting horizontal, and the rigidity is further weakened. Therefore, a hanging vehicle body can not be inclined to the outer bend. When the vehicle needs to bear more goods, the rigidity of the vibration damping system of the whole vehicle can also be regulated.

Description

Band turns to the self-balanced shock mitigation system

Technical field

The present invention relates to the vehicle manufacture, is a kind of shock mitigation system that can regulate rigidity and can realize steering balance automatically, improves traveling comfort and the safety taken.

Background technology

In the bumper that uses now, no matter be the metal spring bumper, air bellow bumper, or liquid damper, the contradiction of elasticity, load-carrying capacity and steering balance exists all the time.Even some technology combines various bumpers, can only be in harmonious proportion contradiction between these several aspects a little, but its structure is extremely complicated, give and implement and safeguard and bring huge difficulty.

Summary of the invention

In order to change damping in present most the use along with the increase of load carrying ability or run into when being higher than the ground-surface obstacle; The problem that rigidity increases; The present invention adopts a plurality of bumpers and Metallic rod to form damping; And the whole dampings of car load are coordinated each other, form the perfect shock mitigation system of damping effect.And adopted damping to connect each other with car load, coordination absorbs simultaneously and subdues and comes from ground-surface vibration, and vibration is further weakened.And Yin Chenei does not carry inequality everywhere and the suspension tilting of car body that causes.Suspension tilting of car body degree in the time of can also alleviating simultaneously the car turning.Can also regulate the bearing capacity of car load shock mitigation system easily.

Technical scheme

The shock mitigation system of band steering balance of the present invention; Be with bumper (comprising the metal spring bumper, perhaps pneumatic bumper, perhaps liquid damper etc.) or rigid metal bar; Connect into star (Y type), triangle (Δ type) or star and leg-of-mutton unitized construction.Each unitized construction comprises three or the bumper more than three or bumper and the combination of rigid metal bar.The structure that three bumpers are formed is a star, and the structure that four bumpers are formed has on the leg-of-mutton summit and connects a bumper again, promptly has a bumper to be directly connected in vehicle bridge and to hang between the car body.Or four bumpers the head connect together, four afterbodys are on tetrahedral four summits.Having two bumpers perhaps to hang car body with vehicle bridge is connected.The connection of six bumpers is on the basis of star, increases a triangular structure again, and this vertex of a triangle is exactly afterbody of three bumpers in the star connection or the like.It is characterized in that bumper is first continuous or join end to end or the tail tail links to each other.Be that the bumper that the natural frequency of vibration is different makes up in this unitized construction, form wide band filtering unit, and realize damping, carrying and three aspect unities of opposites of balance.

Four supporting points of suspension car body respectively are equipped with such combination mechanism, become radial symmetry between four combination mechanisms, and are rotatably connected on crank of central authorities, and crank is fixed on the metallic sheath.Metallic sheath can rotate on center shaft and slide up and down.In each combination mechanism wherein, between bumper and the Metallic rod, between bumper and the bumper, being connected between bumper, Metallic rod and vehicle bridge, the suspension car body all is that rotating joint connects.Between each combination mechanism and the crank also is that rotating joint is connected.When load-carrying greatly perhaps runs into the obstacle that is above the ground level; The originally comparatively vertical damping comparatively level that becomes, the component that load-carrying is decomposed toward horizontal direction is bigger, and the component of vertical direction is less relatively; And increased the stroke of damping operation, this has been equivalent to reduce the rigidity of bumper combination.And concussion passed to other several dampings of car, high frequency oscillation all is absorbed, low frequency oscillation repeatedly absorbs the back overwhelming majority and is absorbed in shock mitigation system.When running into when low-lying, the bumper in the shock mitigation system becomes and is tending towards vertically, shock mitigation system rigidity grow, and its concussion is simultaneously almost repeatedly absorbed in the car load shock mitigation system.So car load jolts with ground-surface is uneven hardly.When turning to, the bend outside pressure increases, so outside damping is compressed, so the vertical bumper that spurs in the inboard damping is tending towards level, reduced stiffness is so the inside suspension car body sinks.So after using shock mitigation system of the present invention, the suspension car body can not tilt to excurvation, descends but car load is whole.When car need carry bigger goods, can also regulate the rigidity of car load shock mitigation system, its integral rigidity is increased.On suspension car body and crank, is connected a load-carrying adjusting elastic draw bar, the supporting power of adjusting car.When the bigger supporting power of needs, load-carrying is regulated elastic draw bar pulling metallic sheath and is turned an angle toward the direction that increases system rigidity and increase, and makes between suspension car body and the vehicle bridge to be unlikely to bump.The length of regulating elastic draw bar changes the size of supporting power.Crank and and its bonded assembly bumper between angle be 0 °-180 °.
