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.
Further, 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.
Further, the propelling rod Connection Block is arranged fixedly all 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.
Further, described carriage middle part is connected with bottom plate by rubber shaft bearing, and bottom plate and vehicle bridge are fixed.
Further, the front end of described carriage is connected with the lower end of cantilever by rubber shaft bearing.
Further, the rear end of described two carriages connects by crossbeam.
The beneficial effects of the utility model are:
1, the utility model is to adopt 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 improve the riding comfort of car load and the traveling comfort of taking greatly.
2, the utility model can obtain lower offset frequency, satisfies higher ride comfort and traveling comfort requirement; Guarantee the system architecture compactness simultaneously, 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 utility model and cantilever lower end adopt rubber shaft bearing to be connected, and carriage middle part and bottom plate 9 are connected by rubber shaft bearing, and its locus of reasonable Arrangement is to guarantee to obtain higher reliability and effects such as minimizing noise, wearing and tearing.
4, simple in structure, easy to use, the handling ease of the utility model, advantage such as it is light to have quality, and cost is low, and the intensity height is high integrated, and comformability is strong, simple and reasonable, safe and reliable, be fit to the mass production requirement.
