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 [0001] The invention relates to a vibration-damping and buffering gooseneck of a semi-trailer. It belongs to the field of mechanical technology. Background technique [0002] At present, semi-trailers have become the main equipment for road transportation. The traditional semi-trailer and tractor are mechanically hard-connected. When the road surface is uneven, the vehicle turns, etc., there will be severe vibration at the connection between the semi-trailer and the tractor, which will intensify the vibration of the semi-trailer and tractor. At the same time, the vibration of the tractor will also be transmitted to the semi-trailer through this mechanical hard connection. This may not only cause damage to the goods transported by the semi-trailer, but also affect the driving performance and driving safety of the vehicle. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a semi-traile...
