Description

A kind of middle-size and small-size passenger vehicle independence air suspension

Technical field

The utility model relates to the Vehicle Engineering technical field, particularly a kind of independent air suspension that is mainly used in middle-size and small-size passenger vehicle.

Background technology

Along with improving constantly of automobile driving speed, dependent suspension more and more can not satisfy the requirement of aspects such as vehicle running smoothness and road-holding property.Therefore, along with the car production development of technology, independent suspension arises at the historic moment and has obtained very big development.

The principal feature of independent suspension is that the wheel that is positioned at vehicle frame or vehicle body both sides is connected with vehicle frame or flexible chassis independently of one another.Present modal independent suspension for vehicle is a wishbone suspension, and the top link of this wishbone suspension and following swing arm can be isometric or not isometric.For the wishbone suspension of isometric formula not, the following swing arm of the top link on its top and bottom is not isometric, top link and following swing arm absorb the transverse force of automobile jointly, therefore lateral stiffness is big, and by reasonably arranging, the positional parameter of wheelspan and front-wheel is changed, to alleviate Tyte Wear in acceptable limited range.Make that the adaptive faculty of automobile road pavement is good, tyre contact patch is big, subsides ground property is good.

For middle-size and small-size passenger vehicle, in order to allow the antero posterior axis load equalization, road-holding property when improving high vehicle speeds, generally all require engine behind front wheel, and engine behind front wheel need take a large amount of spaces, chassis, and require body width broader, simultaneously for middle-size and small-size car, its wheelspan is less than normal, and therefore for the suspension that needs connect tire and vehicle body, its arrangement space can be very narrow and small.Especially for independent suspension, because each wheel flutter is done self-movement with respect to vehicle frame respectively, so its steeraxle must be a breakaway-element.Corresponding therewith, tie rod linkage in the steering gear (a trapezoidal steering hardware that is meant that left and right track arm and tierod and propons body form) also must be divided into two sections or three sections, and is directly driven or driven by steering drag link by the pitman arm of swinging in being parallel to the ground-surface plane.And the breakaway-element steeraxle that generally uses at present with all need a transition arm being connected of vehicle frame, so arrange on the chassis and all to need certain space, and this is difficult to realization under the prerequisite of engine behind front wheel space compactness.Based on all difficulties of above existence, the technological development of the independent front suspension of domestic centering wagon also is in blank out.

The home market is selected for use at the suspension of middle-size and small-size passenger vehicle at present, except a large amount of use steel spring dependent suspensions, the independent suspension product is the torsion bar independent suspension of import, this independent suspension has adopted virtual stub technology, steering swivel is external special exploitation, the domestic steering swivel that does not also have this type of virtual stub, development cost are very expensive again.Because domestic still not have other independent suspension product alternative, can only purchase by import, the price height, for reducing integral vehicle cost, under the prerequisite that guarantees suspension property, market presses for the torsion bar independent suspension that a kind of later-model homemade independent suspension substitutes import.
