Description
[technical field]
The utility model relates to a kind of superimposed trailer gooseneck towing pin assembly that has vibration-damping function.
[background technology]
For improving the integrity of goods transport, existing superimposed trailer suspension system has changed airsuspension system into by the leaf spring suspension system, but the towing pin at superimposed trailer gooseneck place does not have vibration insulating system, still can not make the integrity of goods transport reach optimum efficiency after being assembled on the saddle.
[summary of the invention]
The utility model is to overcome the shortcoming that above-mentioned prior art exists, and a kind of superimposed trailer gooseneck towing pin assembly that has vibration-damping function is provided.
A kind of superimposed trailer gooseneck towing pin assembly that has vibration-damping function is characterized in that the towing pin assembly is made up of air bag assembly, air bag backing plate, load bearing seat, shock absorber, levelling valve, bump rubber, bump rubber bearing, rubber bush, towing pin etc.;
The load bearing seat front portion is provided with the air bag assembly; The load bearing seat front part sides is provided with shock absorber;
The load bearing seat middle part is the bump rubber bearing; Bump rubber is arranged on the superimposed trailer gooseneck; Bump rubber is corresponding and gapped with the bump rubber support position;
The load bearing seat rear portion is columniform mount pad, and mount pad one side is provided with boss makes its aperture less than the opposite side aperture, and opposite side is provided with groove in the aperture; The rubber bush of band steel bushing is packed in the mount pad, and a side is spacing by boss, and opposite side is stuck in the groove spacing with snap ring; U type seat is secured on the crossbeam of superimposed trailer gooseneck, and the extending area at U type seat two ends and steel bushing two ends is affixed; Because the profile of rubber bush and mount pad is cylindrical, its rotational freedom is not restricted, and after towing pin was subjected to from the ground-surface vertical power, whole towing pin assembly can rotate around rubber bush;
Levelling valve is fixed on the superimposed trailer gooseneck, and height regulating rod is fixed on the load bearing seat;
Towing pin is secured on the traction pin plate on the load bearing seat in advance.
When superimposed trailer is normally exercised, the impulsive force that produces because of Uneven road at first is delivered on the towing pin 15, at this moment, load bearing seat drives air bag assembly 2 and shock absorber 5 rotates around rubber bush 14, compression and draw high air bag and shock absorber and make to decay in the certain limit and be delivered on the vehicle frame again from the ground-surface impulsive force, thus the integrity of goods guaranteed.
The utility model is by air bag and the common bearing load of load bearing seat; Cushion road shocks jointly by shock absorber and air bag, impact acceleration is decayed within the certain limit be delivered on the vehicle frame, thereby actv. has been protected handling load.

[specific embodiment]
The utility model will be further described below in conjunction with embodiment and accompanying drawing.
A kind of superimposed trailer gooseneck towing pin assembly that has vibration-damping function is made up of air bag assembly 2, load bearing seat 4, shock absorber 5, levelling valve 8, bump rubber 11, bump rubber bearing 19, rubber bush 14, towing pin 15;
The upper and lower support 7,10 of levelling valve is secured to respectively on superimposed trailer gooseneck and the load bearing seat, and levelling valve 8 and height regulating rod 9 are respectively installed on the upper and lower support of levelling valve.
Rubber bush in the utility model mainly plays the effect of moving spider, allows load bearing seat rotate around it.
The utility model bump rubber 11 is unified into an integral body by bump rubber bearing 19 and superimposed trailer gooseneck, when towing pin 15 drives whole towing pin assembly around rubber bush 14 upward movements, by the bump rubber bearing 19 on the bump rubber 11 collision load bearing seats, make jump on the saddle obtain spacing; When the towing pin assembly drives whole towing pin assembly when rubber bush moves downward, then be to draw high greatest limit by shock absorber 5, make that jumping obtains spacing under the towing pin assembly.
The utility model is connected to load bearing seat on the superimposed trailer gooseneck by the extending area at steel bushing 22 two ends of rubber bush 14, by the gentle capsule backing plate of air bag cover plate whole saddle is unified into an integral body.After towing pin 15 is subjected to from the ground-surface vertical load, drive whole towing pin assembly when rubber bush rotates by load bearing seat, by the levelling valve pilot piping, make air bag and shock absorber after the modification of short time, can return to initial condition rapidly, vehicle is still normally exercised.The utility model can will impact from the ground-surface impact-attenuating in certain limit.
The utility model adopts shock absorber to tilt to install, and makes saddle seem compact, has saved very large space.
