The technical scheme that its technical matters that solves the utility model adopts is: this system has forward mounting and back to hang two partly, forward and backward propelling rod forms framed structure, air bellow, comprehensive shock absorber, stabilizer rod form vibration insulating system, the equilibrium of resolution system structure stress, effectiveness in vibration suppression problem; The forward mounting combined isolator is placed on the propons, and rear overhang hangs up the propelling rod bearing and can change, and joist and back axle connection location are adjustable, resolution system structure applicability problem; The back hangs the joist extrusion molding, and liner brace panel, propelling rod spindle nose adopt double layer innerliner wire loop Bush structure, solve member problem in service life.

In the forward mounting, last longitudinal rod, down longitudinal rod is parallel, and is vertical with lateral rod, is connected the formation framed structure respectively with chassis, propons by bearing; Forward mounting air bellow, comprehensive shock absorber are arranged in juxtaposition, and vertical ground is the major and minor fulcrum of load, and stabilizer rod laterally connects, and forms the frame arrangement vibration insulating system; Forward mounting propelling rod, comprehensive shock absorber, stabilizer rod directly are connected with total bearing, and the air bellow bearing is installed on total bearing, forms in conjunction with bearing, is installed on the axle beam.In the forward mounting, passenger-carrying chassis, air bellow, comprehensive shock absorber, left and right sides support, propons and wheel form load carrying device, and 4 longitudinal rods transmit the vertical gravitation of vehicle body, system's stress equalization, and overall structure is strong, can satisfy the requirement of different passenger vehicles to load.Can propons not needed processing in addition at the propons side travel when propelling rod bearing, air bellow and absorber seat are installed again, just can satisfy the requirement of various passenger vehicle width dimensions.

During the back hung, last longitudinal rod, following longitudinal rod became " V " to arrange respectively, are connected with chassis, back axle, joist respectively by bearing, form framed structure; Upper thrust rod bearing basic fixed is on rear-axle casing, and propelling rod bearing and basic bolt together are changed different-thickness propelling rod bearing, can satisfy the requirement of differing heights vehicle frame; The back hangs joist, adopt high strength bolt by upper and lower bearing, joist and vehicle bridge are linked together, vertically the bearing pin location, laterally can adjust the position of upper and lower bearing on axle housing, to satisfy different model, different in width passenger vehicle to the laterally requirement of (axially) size.The back hangs joist, and its upper and lower plate is integral extrusion forming, the horizontal brace panel of intermediary interface place liner, and the vertical brace panel of the liner that keeps at a certain distance away, the connection hole adds the semicircle brace panel, is welded into integral body, and is in light weight, heavy burden intensity height; During the back hung, passenger-carrying chassis, air bellow, comprehensive shock absorber, joist, axle housing and wheel formed load carrying device, can satisfy the requirement of large and medium bus to different load.

In the forward and backward suspension, propelling rod goalpost oblique crank Z head adopts the double layer innerliner wire loop, and filling polysulphide rubbers injection-compression molding becomes Bush's structure; The forward mounting stabilizer rod is connected with bearing, and employing vertebra degree is 1: 10 cone hole, axle assembling; The back hangs stabilizer rod and is connected with joist by pipe link, and pipe link two ends spindle nose adopts Bush's structure.

The beneficial effects of the utility model are: applicability is strong, and it is little to take up room, and can be fit to the requirement of different load, different size large and medium bus; Stress equalization, good damping result; Compact conformation, long service life; Can reduce the destruction of passenger vehicle road pavement, keep the safety and comfort of passenger and chaufeur.
