A kind of school bus with single longitudenal arm after air suspension, wherein: comprise carriage, vehicle frame, vehicle bridge, air bag, bumper and propelling rod, two carriages be arranged in parallel, and the carriage front end is connected with vehicle frame by cantilever, middle part and the vehicle bridge of carriage are fixed, the carriage rear end is provided with air bag, and air bag lower end and carriage are fixed, and the air bag upper end is fixed with vehicle frame, vehicle bridge is connected by propelling rod with vehicle frame, also be provided with bumper between carriage and the vehicle frame, upper end and the vehicle frame of bumper are fixed, and the lower end of bumper is connected with carriage.
Technical scheme of the present invention can also be achieved in that described propelling rod is the V-type propelling rod, and the tip of V-type propelling rod is connected with vehicle bridge, and two divergent ends of V-type propelling rod are connected with vehicle frame respectively.
Technical scheme of the present invention can also be achieved in that and all be fixed with the propelling rod Connection Block on described vehicle bridge and the vehicle frame, the tip of V-type propelling rod and the propelling rod Connection Block on the vehicle bridge are hinged, two divergent ends of V-type propelling rod respectively with vehicle frame on the propelling rod Connection Block hinged.
Technical scheme of the present invention can also be achieved in that described carriage middle part is connected with bottom plate by rubber shaft bearing, and bottom plate and vehicle bridge are fixed.
Technical scheme of the present invention can also be achieved in that the front end of described carriage is connected with the lower end of cantilever by rubber shaft bearing.
Technical scheme of the present invention can also be achieved in that the rear end of described two carriages connects by crossbeam.
Beneficial effect of the present invention is:
1, the present invention adopts air bellow to replace steel spring, and because the rigidity of air bellow is little, offset frequency is low, can better relax the ground impact load, and then can greatly improve the riding comfort of car load and the traveling comfort of taking.
2, the present invention can obtain lower offset frequency, satisfies higher ride comfort and traveling comfort requirement; Guarantee that simultaneously system architecture is compact, assembling is convenient, makes resource obtain rationalizing and uses; On the basis of the reliability requirement that the assurance system uses, optimize parts design, rationally reduce weight, reach the purpose that reduces vehicle operating cost.
3, carriage front end of the present invention and cantilever lower end adopt rubber shaft bearing to be connected, be connected by rubber shaft bearing with bottom plate 9 in the middle part of the carriage, and its locus of reasonable Arrangement are to guarantee to obtain higher reliability and noise reduction, wearing and tearing texts.
4, simple in structure, easy to use, the handling ease of the present invention, it is light to have quality, and cost is low, and intensity is high, and is high integrated, and the advantages such as strong adaptability are simple and reasonable, safe and reliable, are fit to the mass production requirement.
