Description
Technical field
The utility model relates to a kind of fort formula special trailer, the horizontal swing angle device of the hinged automatic adjustment of tail after especially a kind of fort formula special trailer.
Background technology
Fort formula special trailer, for logging transporter, be uneven because as a rule transport routes are rugged, road conditions are very poor, the road surface that the desk-top trailer of tractor truck towed artillery travels is irregular, Shi Erzhu car (i.e. tractor truck) there will be the pivot angle of transverse direction about-5 °, but existing fort formula special trailer horizontal pivot angle is under steam but at about+5 °, be round orifices orientation pin because after existing fort formula special trailer, tail is hinged, gap is little, therefore horizontal pivot angle is little, supplementary horizontal pivot angle size is carried out by the distortion of draw bar completely under special road conditions, after this fort formula special trailer, tail articulated manner is the draw bar of the main car of hinge and fort car, not only bear longitudinal traction effect, but also bear the distortion action of horizontal pivot angle, in the course of time, draw bar and vehicle frame are all yielding, fracture, and turn to effort dumb.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provides the hinged automatic adjustment of tail after a kind of fort formula special trailer horizontal swing angle device, this device can increase horizontal pivot angle amplitude, can effectively realize draw bar along with under the unbalance condition that do not coexist of road conditions run through rotate freely in pipe alerting ability, safety, high efficiency transport effect.
The technical scheme that the utility model solves the employing of its technical matters is: comprise traction seat, draw bar and pipe, draw bar all has circular hole at leading section and rearward end, the leading section of draw bar is articulated with on traction seat by circular hole, the rearward end of draw bar and pipe grafting are also fixed by circular hole, described traction seat has the long circular hole of relative above-below direction in both sides, draw bar and traction seat are hinged by the long circular hole of the circular hole on draw bar leading section and traction seat, the rear end of pipe offers the long circular hole of the left and right directions aligned up and down, after the rearward end of draw bar and pipe grafting, realize hinged by the long circular hole on the circular hole in the rearward end of draw bar and pipe.
Compared to existing technology, the horizontal swing angle device of the hinged automatic adjustment of tail after a kind of fort formula special trailer of the present utility model, it is the long circular hole traction seat on the main car of traction being arranged above-below direction, and then draw bar is contained in the long circular hole of traction seat, on the pipe at fort formula special trailer rear, offer the long circular hole of the left and right directions aligned up and down simultaneously, now define longitudinal direction by the oval arc hole of the left and right directions on the long circular hole of the above-below direction of traction seat and pipe, laterally all increase and can reach ± the pivot angle of 7 °, completely solve the discrepancy in elevation and left and right, road surface drop before and after road surface like this, also can solve the alerting ability turned to simultaneously.

Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to protection domain of the present utility model.
Fig. 1 to Fig. 6 shows the structural representation of the utility model preferred embodiment, the horizontal swing angle device of the hinged automatic adjustment of tail after a kind of fort formula special trailer in figure, comprise traction seat 1, draw bar 2 and pipe 3, draw bar 1 all has circular hole at leading section and rearward end, the leading section of draw bar 2 is articulated with on traction seat 1 by circular hole, the rearward end of draw bar 2 and pipe 3 grafting are also fixed by circular hole, described traction seat 1 has the long circular hole 4 of relative above-below direction in both sides, draw bar 2 is hinged by the long circular hole 4 of the circular hole on draw bar 2 leading section and traction seat 1 with traction seat 1, the long circular hole 4 of the left and right directions aligned up and down is offered in the rear end of pipe 3, after the rearward end of draw bar 2 and pipe 3 grafting, realize hinged by the circular hole in the rearward end of draw bar 2 and the long circular hole 4 on pipe.Long circular hole 4 according to traction seat 1 above-below direction can regulate front haulage car automatically, the front and back discrepancy in elevation on rear fort formula special trailer road surface, also automatically can regulate the drop of road surface transverse warping injustice simultaneously; The long circular hole 4 of upper and lower two transverse directions (left and right directions) in pipe 3 rear end that rear fort formula special trailer vehicle frame assembles is hinged with draw bar 2 rear end, serve automatic rotation, automatically regulate the effect of horizontal pivot angle, along with the road surface of distortion injustice regulates automatically, even if under severe road conditions, have effectively achieved the efficient importance of transportation safety, meet customer requirement and the market demand.
Further, enlarged drawing see the leading section of draw bar 2 and the connection structure assembly (K1 and K2 place) of traction seat 1: as shown in Figure 3 and Figure 4, described draw bar 2 is articulated with long circular hole 4 place of traction seat 1 by front bearing pin 5, flat gasket, spring cotter.Particularly, front bearing pin 5 through in the circular hole on the long circular hole 4 of traction seat 1 and draw bar 2 leading section, add flat gasket, load onto spring cotter.
Again further, see the rearward end of draw bar 2 in the enlarged drawing of the connection structure assembly (G1 and G2 place) of pipe 3: as shown in Figure 5 and Figure 6, after the rearward end of described draw bar 2 and pipe 3 grafting, be articulated with in long circular hole 4 by rear pin shaft 6, flat gasket, spring cotter and brace panel 7, described brace panel 7 also offers the long circular hole 4 corresponding with pipe 3.Particularly, by draw bar 2 rear end part and pipe 3 grafting, the long circular hole 4 on the circular hole of draw bar 2 rearward end and pipe 3 is aligned simultaneously, then rear pin shaft 6 through in the long circular hole of brace panel 7, then use flat gasket, spring cotter by its pinning.
The utility model traction seat 1 both sides adopt the long circular hole 4 of vertical (above-below direction), and draw bar about 2 can be regulated automatically according to road conditions, and draw bar 2 also can leave certain space according to the uneven automatic rotation of road conditions distortion simultaneously; The utility model pipe 3 and brace panel 7 adopt the long circular hole 4 of upper and lower transverse direction (left and right directions), make draw bar 2 can regulate horizontal pivot angle according to the uneven automatic rotation of road conditions distortion; The utility model have employed draw bar 2 rear ends and forms the relative long circular hole 4 for cross direction, this structure makes main car and trailer normally can travel on the road surface of road conditions height distortion injustice, and turns to the advantages such as flexible, horizontal pivot angle rotates freely, efficient transportation.
The above; be only preferred embodiment of the present utility model, not any pro forma restriction done to the utility model, every according to technical spirit of the present utility model; to any simple modification done by above embodiment and equal change, all fall within protection domain of the present utility model.
