Abstract
The invention relates to a vibration-reducing buffer gooseneck of a semitrailer. The vibration-reducing buffer gooseneck comprises an upper vibration-reducing airbag bracket, a vibration-reducing airbag, a lower vibration-reducing airbag bracket, a hydro-pneumatic spring cylinder, an air discharge switch valve, a pneumatic depressurizing valve, an air charge switch valve, a longitudinal gooseneck beam, a rear gooseneck crossbeam and a front gooseneck crossbeam. According to the vibration-reducing buffer gooseneck of the semitrailer, the relative vertical vibration of a connecting part between a tractor and the gooseneck of the semitrailer can be effectively reduced, relative vibration between the tractor and the semitrailer in the driving direction can be reduced, the pressure and the height of the vibration-reducing airbag can be conveniently regulated, and the requirements of vehicles with different heights and different deadweights are met; under the working conditions of emergency brake, collision and the like of the vehicle, the hydro-pneumatic spring cylinder can be used for effectively reducing impact on the semitrailer, so that the safety of transported cargoes is guaranteed to the greatest extent.
Description
Technical field
The present invention relates to a kind of semitrailer vibration reduction and cushioning gooseneck.Belong to field of mechanical technique.
Background technology
At present, semitrailer has become main force's equipment of highway transportation.Using mechanical between traditional semitrailer and tractor
Hard link, when Uneven road, when turn inside diameter, semitrailer and tractor junction occur violent vibration,
Thus aggravating the vibration of semitrailer and tractor.Meanwhile, the vibration of tractor also can be delivered to by this mechanical Hard link
Semitrailer.This not only possible double trailer goods carried causes to damage, simultaneously can be to the driving performance of vehicle and driving safety
Property impacts.
Content of the invention
It is an object of the invention to overcoming above-mentioned deficiency, provide a kind of semitrailer vibration reduction and cushioning gooseneck, its structure is simple, gas
Dynamic system is succinct, easy to operate.This device both can reduce the Relative vertical of tractor and semitrailer gooseneck connecting portion effectively
Vibration, the Relative Vibration that also can reduce between tractor and semitrailer on direction of traffic, so that semitrailer is run more steadily, more pacify
Entirely, also farthest protect the safety of transported goods.
The object of the present invention is achieved like this：A kind of semitrailer vibration reduction and cushioning gooseneck, it includes setting successively from top to bottom
Vibration damping air bag bracket, vibration damping air bag and the vibration damping air bag bottom bracket put, and hydro-pneumatic spring cylinder, air inlet switch valve, pneumatic subtract
Pressure valve, exhaust switch valve, gooseneck longeron, gooseneck rear cross beam and gooseneck front beam, described vibration damping air bag bracket is installed on gooseneck
At front beam, guide groove is adopted to coordinate and gooseneck longeron between, described vibration damping air bag bottom bracket is fixed on tractor saddle, described
Vibration damping air bag bracket is placed on the guide pillar being arranged on vibration damping air bag bottom bracket, described vibration damping air bag bracket rear end and oil gas
Spring cylinder one end is hinged, and the described hydro-pneumatic spring cylinder other end is hinged with gooseneck rear cross beam, described pneumatic pressure-release valve import and source of the gas
Connect, outlet is connected with described air inlet switch valve one end, and the described air inlet switch valve other end is opened with vibration damping air bag and exhaust respectively
Close valve to connect, the described exhaust switch valve other end is directly communicated to air.
Compared with prior art, the invention has the beneficial effects as follows：
The present invention connects semitrailer gooseneck and tractor by vibration damping air bag, thus effectively reduce semitrailer and tractor it
Between Relative vertical vibration.The blowing pressure in vibration damping air bag can be adjusted by pneumatic pressure-release valve, by air inlet switch valve and row
Exhaust switch valve can adjust vibration damping airbag aeration amount, thus adapting it to the semitrailer of different loading capacity and multi-form.Subtract
The air bag bracket that shakes is coordinated by guide groove with gooseneck longeron, simultaneously horizontal after hydro-pneumatic spring cylinder connects vibration damping air bag bracket and gooseneck
Beam, the Relative Vibration that can effectively reduce between tractor and semitrailer on direction of traffic, occur during travelling simultaneously
Bring to a halt, collide etc. operating mode when, by impacting that hydro-pneumatic spring cylinder can reduce that semitrailer is subject to, thus farthest ensureing
The safety of transport goods.
