Description
Technical field
The present invention relates to semitrailer field, a kind of semitrailer high abrasion suspension arrangement.
Background technology
Suspension arrangement of semitrailer is one of critical piece of semitrailer, and its Main Function is semitrailer axle componental movement
Parts and semitrailer crossbeam are tied effectively and reasonably and firmly.The suspension arrangement of highway semitrailer, suspension holdfast is welded on
Semitrailer main longitudinal grider lower end, the load that vehicle body bears passes to leaf spring by suspension holdfast, then passes on axletree；Axletree
Opposite side is connected by stayed mast and an adjacent dumb iron, is used for bearing horizontal force.Use this outstanding
The semitrailer of extension mode, when the wheel contact ground having during some wheel hangings, arises that all load of semitrailer are equal
The phenomenon born by the wheel on contact ground, at this moment, on the one hand there is a possibility that other axletrees overload, and on the other hand can reduce many
The pull strength of shaft-driven vehicle, thus easily cause wheel, axletree and leaf spring because damaging beyond its intensity time limit.
Meanwhile, during vehicle travels, every steel plate of the leaf spring of suspension arrangement of semitrailer all can be transported up and down
Dynamic, thus produce friction, and this friction can interact, so that steel spring plate easily damages, thus gives driver
Personal safety bring very big hidden danger.
Summary of the invention
In order to make up the deficiencies in the prior art, heretofore described a kind of semitrailer high abrasion suspension arrangement, it can
Solve the unsettled problem of road surface piece wheel of jolting, and the abrasion of leaf spring and bearing pin can be slowed down.

Pad, described each U-bolt is all nested with a Wear-resistant skid-proof rubber set, each bearing pin is all nested with No. two wear-resisting antiskid rubbers
Gum cover, is disposed with Wear-resistant skid-proof rubber pad between described suspension holdfast and leaf spring；Number Wear-resistant skid-proof rubber set, No. two
The effect of Wear-resistant skid-proof rubber set and Wear-resistant skid-proof rubber pad is the mill slowing down U-bolt, steel spring plate, suspension holdfast and bearing pin
Damage, and a Wear-resistant skid-proof rubber set, No. two Wear-resistant skid-proof rubber sets and Wear-resistant skid-proof rubber pad also can be carried out by cooling main body
Cooling, prevent because of with high temperature and accelerated wear test.
Described cooling main body includes nozzle, cooling supervisor and cooling tubule, and described nozzle quantity is two, two nozzles
Lay respectively at directly over front spring and rear spring；Described cooling is responsible for one end and is connected two nozzles, and cooling supervisor's other end leads to
Cross external hydraulic pump to be connected with coolant water tank；Described cooling tubule quantity is four, and four cooling tubule one end all connect
Cooling supervisor, four cooling tubule other ends embed in the inlet opening of each grasswort respectively；Described front spring and rear spring are
Upper end is mounted on temperature sensor；When the front spring that temperature sensor detects and rear spring temperature are too high, then cool down master
Body running, a coolant part sprays through nozzle, and to lower the temperature leaf spring, U-bolt and suspension holdfast, another part is through cold
But in tubule flows into each grasswort, so that bearing pin is lowered the temperature.
Beneficial effect:
(1) position of vehicle bridge in traditional approach is moved on to leaf spring rear and front end in the middle part of leaf spring by the present invention, and
Vehicle bridge can be rotated around balance axle by leaf spring, and it can solve the problem that the problem that the road surface piece wheel that jolts is unsettled so that nothing
Under which kind of jounce condition of opinion, each wheel all can touch with ground, it is to avoid the overload of other axletrees, extends suspension arrangement
Service life.
