The four link suspension support axle device has the advantages that the coordination and reliability of movement of the whole system can be ensured. The whole system is convenient for installing, has light deadweight and low price and improves the vehicle cost performance greatly.
Description
Technical field:
The present invention relates to four connection-rod hovering loading-bridge device a kind of and the drive axle interlock, belong to commercial Chefei and drive carrying bridge and air suspension apparatus, this device is connected to form work system by support, bearing with vehicle frame, carrying bridge, air spring suspension etc.
Background technology:
Can promote the follow-up bridge air suspension apparatus does not have in actual use and can well be used, incompatibility national legislation requirement, and conventional drive axle leaf spring or hovering draft hitch Heavy Weight, price height.
Summary of the invention:
The purpose of this invention is to provide a kind of four connection-rod hovering loading-bridge device that has good ride comfort, can protect ground-surface and drive axle interlock well; this device compares with conventional drive axle draft hitch; own wt is light; increased the charge material amount of vehicle; cost of price is much lower, has improved the cost performance of vehicle greatly.
The objective of the invention is to be achieved through the following technical solutions:
The present invention includes preceding end support, back end support, air bellow, air bellow bearing, carrying bridge, guide arm, shock absorber, pneumatic control components, it is characterized in that: preceding end support is fixed on the vehicle frame, air bellow top is fixed by back end support and vehicle frame, the bottom is fixed by air bellow bearing and carrying bridge, two guide arms and air bellow bearing and preceding end support connect and compose parallelogram linkage, and shock absorber connects vehicle frame and air bellow bearing.
Described pneumatic control components is made up of tracheae, pressure regulating valve, load sensing valve, compression indicator, the input end tracheae of pressure regulating valve connects gas cylinder, the mouth tracheae of pressure regulating valve links to each other with the input end tracheae of load sensing valve, the mouth tracheae of load sensing valve links to each other with manometric input end tracheae, and manometric mouth tracheae is communicated with the air bag of air bellow.
Guide arm and preceding end support, air bellow bearing are by its in-to-in rubber bush bonded assembly.
Advantage of the present invention is: the harmony and the reliability that can guarantee the whole system motion.Parallelogram linkage makes the motion of carrying bridge and air bellow form comparatively ideal translation track; The use of air bellow and pneumatic control components has improved vehicle ride comfort; The side force in the vehicle ' has effectively been resisted in the use of rubber bush.Whole system is easy for installation, and low from heavy and light, price, the cost performance of vehicle is greatly improved.
Four connection-rod hovering loading-bridge device with the drive axle interlock of the present invention can mate installation on Liang Qiao, three bridges and multiaxis commercial vehicle/comm..vehicle.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is that the A of Fig. 1 is to revolved view;
Fig. 3 is a gas circuit control chart of the present invention, and the direction of arrow is air flow line among the figure.
The specific embodiment:
With reference to accompanying drawing, end support 2 is fixed on the vehicle frame 1 before the device of the present invention, and air bellow 6 tops are fixing with vehicle frame 1 by back end support 5, and air bellow 6 bottoms are fixing with carrying bridge 7 by air bellow bearing 8, and air bellow 6 bears vertical power.Air bellow bearing 8 is connected with preceding end support 2 by guide arm 3, guide arm 3 connects into an integral body with device, constitutes parallelogram linkage, makes air bellow 6 and carrying bridge 7 form the translational motion track, do not rotate, guarantee under good state, to work in the vehicle ' process.The spring performance that air bellow is desirable can play good buffering, damping of vibrations.The guide arm 3 of quadrilateral connecting rod mechanism is connected by the rubber bush of inner major diameter, length with support 2, bearing 8, vibration that can reducing mechanism, and can resist side force.Shock absorber 4 connects vehicle frame 1 and air bellow bearing 8, and the vibration of attenuation factor rapidly makes system's smooth working.Pressure regulating valve 11 input end tracheaes connect gas cylinder, and pressure regulating valve 11 has reduced gas cylinder and come atmospheric pressure, define the maximum gas pressure in the air bellow, unlikelyly cause that air pressure is excessive and damage the system zero parts; Pressure regulating valve 11 mouth tracheaes link to each other with load sensing valve 10 input end tracheaes, and load sensing valve 10 is the important spare parts in the gas circuit control, can make carrying bridge and driving rear axle bear load in proportion, and unlikely propulsive effort deficiency and the braking force of causing is influenced; Load sensing valve 10 mouth tracheaes link to each other with compression indicator 9 input end tracheaes, and compression indicator 9 mouth tracheaes are communicated with air-spring bellows, and compression indicator 9 can show the operation pressure in the air bellow in good time.
Package unit has well guaranteed the ride comfort of vehicle, has reduced the impact that causes because of the road surface is uneven, has reduced the parts early failure that causes because of resonance; Alleviated the impact that vehicle bridge is subjected to, and transmission shaft, Tyte Wear, fuel oil consumption saved.Minimizing improves all transfer efficients of vehicle because of the standing time of maintenance, creates economic benefit; Reduce the be hit bounce-back of road pavement of vehicle bridge, the damage of road pavement plays a protective role.Used load sensing valve in this cover mechanism.Load sensing valve makes carrying bridge and driving rear axle bear load in proportion, be vehicle in zero load in heavily loaded process, the load of carrying bridge is also changed from small to big, avoid air bellow air pressure constant, the carrying bridge was too much shared load when vehicle was unloaded, make the driving rear axle carrying too small, cause propulsive effort deficiency and braking force influenced.Pressure regulating valve makes the interior air pressure of air bellow within the maximum gas pressure scope of setting simultaneously, the unlikely situation of damaging the system zero parts because of bearing load is excessive that causes.
