A kind of semitrailer high abrasion suspension arrangement
Technical field
The present invention relates to semitrailer field, specifically a kind of semitrailer high abrasion suspension arrangement.
Background technology
Suspension arrangement of semitrailer is one of critical piece of semitrailer, and main function is semitrailer axle componental movement
Component effectively and reasonably and is firmly tied with semitrailer crossbeam.The suspension arrangement of highway semitrailer, suspension holdfast are welded on
Semitrailer main longitudinal grider lower end, the load born on vehicle body passes to leaf spring by suspension holdfast, then passes on axle;Axle
The other side is connected by the stayed mast dumb iron adjacent with one, for bearing horizontal force.Using this outstanding
The semitrailer of extension mode, when the wheel having contacts ground and some wheel hangings, all load that just will appear semitrailer are equal
At this moment the phenomenon that wheel by contacting ground is born on the one hand there is a possibility that other axles overload, on the other hand can reduce more
The tractive force of shaft-driven vehicle, to easily cause wheel, axle and leaf spring to be damaged because exceeding its intensity time limit.
Meanwhile during vehicle travels, every steel plate of the leaf spring of suspension arrangement of semitrailer can all be transported up and down
Dynamic, to generate friction, and this friction can interact, so that steel spring plate easily damages, to give driver
Personal safety bring very big hidden danger.
Invention content
In order to make up for the deficiencies of the prior art, heretofore described a kind of semitrailer high abrasion suspension arrangement, can
It solves the problems, such as that bumpy road piece wheel is hanging, and the abrasion of leaf spring and axis pin can be slowed down.
The technical solution adopted by the present invention to solve the technical problems is:A kind of semitrailer high abrasion suspension arrangement, including
