[technical field]
The utility model relates to automotive suspension structure, particularly a kind of air suspension of vehicle-borne lifting bridge band follow-up steering function.
[background technology]
Constantly perfect along with developing of automobile industry and arteries of communication, high-grade commercial vehicle/comm..vehicle demand is increasing, becomes the developing direction of commercial vehicle/comm..vehicle.Particularly in order to prevent transport vehicle " overload ", country has formulated new standard, has promoted developing rapidly of large-scale multiaxis commercial vehicle/comm..vehicle.
The sprung parts of domestic production at present is divided into leaf spring suspension and air suspension two big classes, and wherein air suspension can be divided into full air suspension and compound suspension (by leaf spring and the common suspension system of forming of air bag assembly) again.
Spring type suspension rear suspension structure is by chassis side rail, crossbeam, steel spring and support thereof, shock absorber and upper and lower support thereof are formed, vertical load is all born by leaf spring, so the vibration isolation of system is poor, ride comfort is bad, and empty, at full load overall height changes greatly, i.e. boarding is poor, but anti-roll capability is better than combined type air suspension.
Combined type air rear suspension structure is made up of chassis side rail, crossbeam, steel spring and support thereof, air bag assembly and upper and lower bearing thereof, shock absorber and upper and lower support thereof.The vertical load of automobile is carried jointly by leaf spring and air bag assembly, and it is suspended on vibration isolation, the ride comfort than leaf spring and increases, but also has gap with the commercial vehicle/comm..vehicle standard of higher one-level, and its anti-roll capability of spring type suspension descends to some extent relatively.
[summary of the invention]
The utility model technical issues that need to address provide a kind of have good ride comfort, cargo transportation security, road-holding property, can increase substantially whole bearing capability, and the all-air suspension mechanism of the band follow-up steering that can when vehicle is unloaded, follow-up bridge can be lifted.
The utility model is its problem of solution by following technical proposals: a kind of all-air suspension mechanism of vehicle-borne lifting bridge band follow-up steering comprises vehicle frame, vehicle bridge and the wheel hub that is rotationally connected with vehicle bridge.The vehicle frame both sides are provided with a carrying air bag assembly respectively, and the upper end of this carrying air bag assembly is fixedly connected on the below of vehicle frame by the air bag upper cover plate, and its lower end is fixedly connected on the air-bag support, and this air-bag support is connected with axle attachment; Two outsides of vehicle frame also are fixedly equipped with the preceding end support of vertical propelling rod respectively, be somebody's turn to do and pass through upward vertical propelling rod of heavy lining flexible connection and following vertical propelling rod on the preceding end support of vertical propelling rod, the other end that should go up vertical propelling rod and following vertical propelling rod is movably connected on the air-bag support by heavy lining, and make this two propelling rod be parallel shape, a lifting air bag assembly is fixedly connected between vertical propelling rod and the following vertical propelling rod; Captive joint one damper bracket is also distinguished in the both sides of vehicle bridge, and another damper bracket is fixedly connected on the steering swivel of both sides wheel hub, and an end of servo-actuated shock absorber is movably connected on the damper bracket, and its other end is movably connected on the damper bracket.
The utility model is owing to adopted technique scheme, vehicle handling stability and cargo transportation security had both been kept, improved whole bearing capability greatly, reduced the follow-up bridge wear on tyres, and when vehicle is unloaded, follow-up bridge can be lifted, reduce vehicle oil consumption, further improve the vehicle its usage economy.
