Description
Technical field
The present invention relates to a kind of heavy-duty car air suspension, more particularly to a kind of non-driven support bridge band airbag lift
The single swing arm air suspension system of device.
Background technology
For multi-axle heavy type automobile, when vehicle deadhead operation, the effect that non-driven support bridge plays is smaller, this
When, the driving support bridge of vehicle just undertakes the weight of vehicle body enough, and does not need non-driven support bridge to share stress,
But existing structure is limited to, during vehicle deadhead operation, the tire in non-driven support bridge still contacts with ground, causes tire to grind
Damage, and tire contacts with ground and resistance be present, correspondingly also increases oil consumption during vehicle zero load.
The content of the invention
The problem of in background technology, the present invention propose a kind of list of the non-driven support bridge with airbag lift device
Swing arm airsuspension system, the single swing arm air suspension system include two sets and are oriented to arm assembly, through beam and two air bullets
Spring；The guiding arm assembly includes being oriented to arm support, leading arm and connector；One end of the leading arm turns with being oriented to arm support
Dynamic connection, the other end of leading arm are connected with the downside of insertion beam end, the leading arms on two sets of guiding arm assemblies respectively with
Through beam both ends are corresponding；The lower end of the air spring with penetrate beam end upper side be connected, two air springs respectively with
Through beam both ends are corresponding, and the upper end of air spring is connected by support base with vehicle frame, and two air springs correspond to two branch respectively
Support seat；Support bridge is horizontally installed on the top of two sets of guiding arm assemblies, and two sets of connectors being oriented on arm assembly will be accordingly oriented to
The middle part of arm is connected with support bridge；
Its innovation is：Airbag lift device is provided with the single swing arm air suspension system；The airbag lift dress
Put and be made up of lifting air bag, lift arm, link and support arm；The lifting air bag is arranged on above through beam, two air
Opening position between spring, is lifted between air bag and through beam spaced, lifts the force direction and air spring of air bag
Force direction is parallel；The lift arm is inverted U-shaped, and the downside and the upper surface of lifting air bag of lift arm depressed part connect
Connect, the both ends of lift arm opening portion are respectively positioned at the both sides of through beam axial direction；Upper side and through beam in the middle part of the link
Downside connection, the position of link positioned at the underface of lifting air bag, the both ends of link respectively with lift arm opening portion
Both ends connection；The support arm is U-shaped structure, and support arm depressed part is arranged between lifting air bag and through beam, support arm
The upper side of depressed part is connected with lifting the lower surface of air bag, between being left between the downside of support arm depressed part and through beam
Every the both ends of support arm opening portion are connected with two support bases respectively.
The present invention principle be：When heavy-duty car is in loading conditions, control air spring is in inflated condition, lifting
Air bag is in air deflating state, and the tire at support bridge both ends contacts with ground, when surface relief, support bridge, leading arm and insertion
Beam all moves up and down therewith, and now, because lifting air bag is in air deflating state, lift arm freely can also follow through beam to transport
Dynamic, now, airbag lift device does not work；When heavy-duty car is in bare weight state, control air spring be in air deflating state,
Lifting air bag is in inflated condition, and the axial length for lifting air bag is forced to extend, because the lower end for lifting air bag passes through support
Arm is fixed on support base, is lifted the lower end of air bag and relative displacement can not be occurred with vehicle frame, the length for lifting air bag can only be upward
Extension, at this moment, lift arm will be pulled up in the presence of lifting air bag upper end, and link and through beam are also just upward
Lift, because again the end of leading arm is connected on through beam, support bridge links together with leading arm, support bridge and its two
The tire at end is just pulled up, and after support bridge is promoted to certain altitude, tire in support bridge is just and surface separation
, this can effectively reduces the abrasion of tire, and reduces oil consumption；
Because single swing arm air suspension system is common apparatus of the prior art, it is contemplated that innovative point of the invention is main
It is the installation airbag lift device in single swing arm air suspension system, then inventor only makees to single swing arm air suspension system
Simple to introduce, in the prior art, damper, anti-sway bar etc. have been there is likely to be in single swing arm air suspension system, and other are filled
Put, just do not describe one by one herein, the detailed construction of single swing arm air suspension system, those skilled in the art can be found in existing
Technology.
The method have the benefit that：Propose a kind of simple pendulum arm of the non-driven support bridge with airbag lift device
Airsuspension system, non-driven support bridge can be lifted up by the program in vehicle zero load, so as to reduce the mill of corresponding tire
Damage and reduction oil consumption.
