[technical field]
The utility model relates to the rear overhang shelf structure, air suspension structure behind particularly a kind of full-floating light bus four gasbags.
[background technology]
Traditional suspension system as elastic element, adopts this suspension pattern with the spring of steel or leaf spring, always need seek a meticulous balance in the middle of road-holding property and traveling comfort.If improved road-holding property, then can influence travelling comfort; If improved travelling comfort, manoeuvereability of automobile and stability can reduce again.At present, monosaccate (per car wheel) airsuspension system is at city motor bus, and long-distance bus is used on the heavy duty truck to some extent.This air suspension structure makes the distribution of weight of vehicle even inadequately, and the service life of air bag is low.At the drawback that said structure exists, the utility model has been researched and developed air suspension structure behind a kind of full-floating light bus four gasbags.
[summary of the invention]
Problem to be solved in the utility model is the defective that overcomes prior art, and air suspension structure behind a kind of full-floating light bus four gasbags is provided.
Technical solutions of the utility model are: air suspension structure behind a kind of full-floating light bus four gasbags, comprise vehicle frame, back axle, air receiver, electric air compressor and control unit thereof, and it is characterized in that:
The front end of leaf spring and the flat spring bracket of chassis side rail are hinged, and the middle part of leaf spring is fixed with clevis bolt and Connection Block and back axle central siphon, and the leaf spring caudal end is unsettled;
About air bag each two, totally four, each air bag top is connected with the air bag bearing, and the air bag bearing is fixedly linked on chassis side rail or the frame panel complex, and the air bag bottom is fixed on the leaf spring top airfoil.Air bag is installed with vertical state, so that bear vertical load;
Lateral rod is a straight-bar structure, an end connected to ground be a rubber-bushed straight hole disc pin head, be articulated on the propelling rod upper bracket that links to each other with vehicle frame with bearing pin, an end that links to each other with vehicle bridge is a horizontal ball-and-socket type joint, is fixed on the propelling rod bearing by clevis bolt and axle attachment;
Gas circuit control box, electric air compressor, air receiver, levelling valve and air bag constitute the air-channel system of this air suspension jointly by tracheae.
Because the utility model has adopted air suspension structure behind a kind of full-floating light bus four gasbags, the weight of vehicle can obtain distributing more equably, promptly improve the traveling comfort of vehicle, increased the service life of air bag again, improved the handling and stable of vehicle simultaneously.The high-power compressor of air suspension by a levelling valve on the vehicle frame and a compact carries out tolerance to be augmented, and makes vehicle automatic compensation ride-height under different roads and load condition.
