Abstract
A composite suspension system of a semitrailer comprises a rear support, a variable-cross-section plate spring, a balance beam, a middle support and a front support. The composite suspension system of the semitrailer is characterized in that the variable-cross-section plate spring is fixedly connected with an axle through bolts and an axle installation plate, a composite air bag is arranged on the axle installation plate above the variable-cross-section spring plate, and the upper end of the composite air bag is connected with a frame. According to the composite suspension system of the semitrailer, the composite air bag is additionally arranged on the basis of a steel plate balanced suspension of the traditional semitrailer. Therefore, the composite suspension system of the semitrailer has a variable stiffness characteristic, low natural vibration frequency can be obtained easily, and ride performance of an automobile is improved. During no-load, the air bag is filled with less gas pressure under the control of a solenoid valve, so that the composite suspension system can bear load of the empty frame; during full load, the air bag is filled with a great amount of gas pressure under the control of the solenoid valve, so that the composite suspension system can bear load of the loaded goods; therefore, ride comfort of the automobile is improved greatly.
Description
Technical field
The utility model relates to a kind of superimposed trailer compound suspension frame system.
Background technology
Current superimposed trailer suspension, all to adopt steel spring balance suspension, this is suspended in actual enforcement the impact due to the reverse load producing in the impact of road roughness and vehicle launch damped condition, the suspension strut of superimposed trailer can be subject to the effect of reverse load, under this reverse load repeated action, can there is crack initiation and propagation, and cause unexpected fracture, leave potential safety hazard.
Summary of the invention
The purpose of this utility model is just to provide a kind of simple in structure, lightweight, superimposed trailer compound suspension frame system that productive costs is low.
Superimposed trailer compound suspension frame system of the present utility model, comprise after poppet, changeable section plate spring, equalizing bar, medium-height trestle, front frame, it is characterized in that, changeable section plate spring is fixedly connected with vehicle bridge by bolt, vehicle bridge adapter plate, on the vehicle bridge adapter plate of changeable section plate spring top, composite air bag is installed, the upper end of composite air bag is connected with vehicle frame.
Superimposed trailer compound suspension frame system of the present utility model, is to increase composite air bag on traditional superimposed trailer steel plate balance suspension basis, has change stiffness characteristics, easily obtains lower eigentone, can improve ride of vehicle.When unloaded, by solenoid control, make to be full of in air bag a small amount of gaseous tension, guarantee to bear the load of empty wagons frame, at full load, by solenoid control, make to be full of in air bag a large amount of gaseous tensions, guarantee to bear the load of institute's cargo, the travelling comfort of automobile is greatly improved.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
1-after poppet, 2-changeable section plate spring, 3-composite air bag, 4-equalizing bar, 5-medium-height trestle, 6-reinforced rib, 7-bolt, 8-vehicle bridge, 9-vehicle bridge adapter plate, 10-tension bar, 11-front frame.
The specific embodiment
A kind of superimposed trailer compound suspension frame system, comprise after poppet 1, changeable section plate spring 2, equalizing bar 4, medium-height trestle 5, front frame 11, it is characterized in that, changeable section plate spring 2 is fixedly connected with vehicle bridge 8 by bolt 7, vehicle bridge adapter plate 9, on the vehicle bridge adapter plate 9 of changeable section plate spring 2 tops, composite air bag 3 is installed, the upper end of composite air bag 3 is connected with vehicle frame.
