Description
Technical field
The present invention relates to technical field of automobile parts, more particularly, relate to a kind of adjustable air suspension.
Background technology
Automobile-used suspension gear is the general name that the elastic joint part between automobile chassis frame and the vehicle bridge divides, and is used for supporting frame, transmits various power and moment between road surface and vehicle frame, alleviates and absorbs impact and the vibrations when going.Truck is in motion because load and ground-surface variation; Require suspension stiffness along with variation, general cargo truck all adopts steel spring as suspension, the function of the existing buffering of invar laminated spring, vibration damping; Play power transmission and guiding again; Make suspended structure greatly simplify and low price, though it is there is not stiffness variation in the steel spring low price, fragile.The truck that adopts the equalizing suspension system of steel spring formula is when road traveling; The road surface is very big to the impact meeting of automobile; When particularly on the very poor road surface of road conditions, going, this impulsive force is bigger, causes the infantile failure of automobile parts; To driving the handling very big influence that has, the damage of road pavement is more serious.Comfortable but the complex structure of PS Pneumatic Suspension structure; The combined type air suspension that AIRMATIC Dual Control can be divided into full PS Pneumatic Suspension and be made up of leaf spring and air bag; The vertical load of automobile is carried by leaf spring and air bag jointly; Have the advantages that vibration isolation property is good, ride comfort is high, compare, have more the strong advantage of anti-roll capability with full PS Pneumatic Suspension.
Chinese patent CN200820157153.7 illustrates a kind of combined type air suspension that has leaf spring; Referring to Fig. 1, it discloses a kind of PS Pneumatic Suspension with flat spring bracket, shackle bracket, air bag assembly together support vehicle frame weight, wherein; Flat spring bracket is installed on the front end grasswort of veneer spring; Shackle bracket is installed on the rear end grasswort of veneer spring, bears vertical load together by veneer spring and air bag, improves ride comfort, the stability of running car.Referring to Fig. 2; For the bigger truck of load carrying ability; Three of the following common needs of its vehicle frame or the supporting of above axletree in the installation process of axletree, also need the position relation of the interaxle distance of car, axletree and vehicle frame axis is made adjustment; Prevent that the phenomenon of beat from appearring in axletree, be commonly called as adjustment AB line.The support of suspension is to be fixed on the crossbeam of vehicle frame; Therefore, for rigging position and the direction of adjusting axletree, often need adjust the rigging position of axletree and suspension when mounted; But; The arrangement of existing composite air suspension (like CN200820157153.7) veneer spring and suspension holdfast is unreasonable, is difficult to the axletree beat is made fine setting, can not fully satisfy the automotive use requirement.
Summary of the invention
The technical matters that the present invention will solve is, to the deficiency that above-mentioned prior art exists, a kind of adjustable air rational in infrastructure suspension is provided, and makes the position relation of axletree and vehicle frame axis can access fine setting, the rideability of assurance vehicle.
The technical scheme that the present invention adopts is; A kind of adjustable air suspension is installed in the front frame of PS Pneumatic Suspension, and said front frame is fixed on the vehicle frame; The left and right sides portion of said front frame is provided with first mounting hole, second mounting hole respectively; Between the sidepiece of the left and right sides of said front frame, be provided with Large lining, bolt shaft is passed the axis hole of first mounting hole, second mounting hole and the said Large lining of said front frame, and said Large lining is arranged in the grasswort hole, end of leaf spring; The other end of said leaf spring is clipped in the air bag base of PS Pneumatic Suspension and being connected between the base plate of axletree; Also comprise the eccentric gasket cover that is fixed on said first mounting hole, said eccentric gasket is arranged with eccentric gasket cover heavy stand, on said eccentric gasket cover heavy stand, is provided with eccentric gasket cover slotted hole; The eccentric adjustment ring can rotate on said eccentric gasket cover heavy stand; Said eccentric adjustment ring is provided with accentric regulating ring axis hole, and the major axis of said eccentric gasket cover slotted hole is longer than the shaft hole diameter of said eccentric adjustment ring, and said bolt shaft is passed said regulating ring axis hole, eccentric gasket cover slotted hole.
Second mounting hole of said front frame is provided with concentric regulating ring, and said bolt shaft is passed the axis hole of said concentric regulating ring.
The heavy stand cross section of said eccentric gasket cover is a closed curve, the two ends circular arc that comprises two parallel short sides and connect two parallel short sides, and the distance of said two parallel short sides is suitable with said eccentric adjustment ring diameter.
The end face of said eccentric adjustment ring is provided with the eccentric adjustment ring open slot that the hexagonal head that is used to prevent said bolt shaft is skidded and rotated.
Compared with prior art, the present invention has the following advantages:
Advantage such as that the present invention has is simple in structure, rationally distributed, easy to assembly, easy care, maintenance cost handling and ride comfort low, locomotive are good.Two oblique rubber shear springs have been adopted in the rubber suspension of truck, and assist spring is fixed on the Shackle assembly, and saddle is an integral structure, and the rubber shear spring can be dismantled separately, and the rubber shear spring is connected by a Shackle assembly.
The present invention has good damping effect, provides a kind of rubber flexible to support to heavy duty truck, reduced the vibrations under truck zero load and the load effectively, thereby reduced the injury to people and locomotive, and road pavement also plays the certain protection effect.Can prolong the vehicle operation life-span, reduce the M R expense of truck, improve the comfort level of driving, reduce fatigue, reduce of the infringement of bad road surface goods.
