Description
One, technical field:
The present invention relates to a kind of multiaxis semitrailer, particularly relate to a kind of novel semi-trailer that has automatic synchronization steering mechanism.
Two, background technology:
Semitrailer is the important component part of carrier, and the trailer of present domestic most superimposed trailers does not partly have the function of turning to, and the minimum turning radius and the maximum channel width of car load are big, and maneuvering performance is poor; And trailer wheels can not be made pure rolling when turning, lateral slip power is arranged, and (radius of turn is more little, side force is big more), this side force not only influences the stability of locomotive and semi-mounted, also strengthen range of movement simultaneously, increased the requirement of road width condition, in addition, also strengthen centnifugal force, increased the driving difficulty.Because road width is limited, bogie must be implemented the tune operation in the original place; Even when the inbound/outbound process field, the tune operation is also unavoidable.Existing as shown in Figure 1 superimposed trailer is made up of main car and trailer two parts.Main car provides traction power and turns to, and trailer provides carrying.Generally there is multiaxis (to three) at the trailer rear portion, and these axles can only carry and can not turn to.And superimposed trailer generally all is fixed on the traction crossbeam with vertical form, therefore after main car is being cared for load-carrying, implement to turn to, and during tune, need make the deflection angle greater than 90 °, and trailer car tyre is realized turning to by with ground cliding friction taking place by force.Like this, tyre temperature is raise, the tire internal gas pressure increases, and has increased the possibility of blowing out.If when being equal to or greater than 90 ° of angles and turning to, folding phenomenon can take place in main car and superimposed trailer, because main car is also in operation, then can cause the both sides tire of superimposed trailer to do dragging of horizontal non-rolling, when then tire is laterally dragged under the situation of load-carrying, be about to surface of tyre and ground-surface contact site and scrape, form the major injury of tire.This loss occupies about 60% of whole traffic cost.And tire accounts for that whole automobile be worth about 25%, and plays significant effects in the dynamic property of automobile, economy, stability, operability, ride comfort, safety.And this trailer form is when overcast and rainy driving, and during because of traction braking, trailer promptly can break away, and is very dangerous.Existing a kind of axle steer formula superimposed trailer, this kind superimposed trailer is equipped with oil cylinder at the Trailer car shaft place, makes the corresponding rotation with wheel of Trailer car shaft by hydostatic transmission when tractor truck turns to, and has improved the maneuverability of superimposed trailer, has suitably reduced Tyte Wear.Transversal displacement is bigger during the semi-trailer direction changing of this axle steer formula, turns to servo-actuated poor, can not guarantee that still trailer wheels and main car steering wheel around same instantaneous rotation, promptly turn to synchronously.Also have only a few to be used for the superimposed trailer of defence product transportation, adopted the hydrodynamic power-assisted, the steering hardware of quiet liquid feedback can satisfy operating needs, but complex structure, cost height are not easy to promote.
Distance is excessive between the driving wheel that second shortcoming of existing superimposed trailer is main car and the BOGEY WHEEL of trailer, and overhanging portion is long, can be because the difference of the load-bearing number of axle and load-bearing tire load-bearing pressure difference before and after causing before and after the trailer since like this, before being generally heavy after gently.Because overhanging portion is long,, just must strengthen crossbeam in addition for guaranteeing the necessary security coefficient.Some vehicle be exactly to cause because of the crossbeam insufficient strength trailer after long-term use crossbeam to recessed, thereby the force structure of change trailer influences service life of trailer.
Want to overcome the above problems, will manage at the anterior BOGEY WHEEL that increases of superimposed trailer, will be along with turning to of the main car corresponding automatic steering of BOGEY WHEEL before making, so crucial annexation problem that is to solve preceding BOGEY WHEEL and superimposed trailer and main car, to satisfy simultaneously when main car turns to, steering linkage or mechanism can not with vehicle other not link come in contact, also to guarantee main car turn to superimposed trailer before the turning to synchronously of BOGEY WHEEL, promptly cireular frequency is identical.
Three, summary of the invention:
The present invention overcomes the deficiency that prior art exists, front portion at trailer, the rear portion of main car owner's driving wheel increase a row can be along with turning to of main car the BOGEY WHEEL of corresponding automatic steering, to increase the supporting point of trailer front portion, thereby reduce the length of trailer overhanging portion, reduce the load-bearing of main car owner's driving wheel, thereby improve the stressed of whole chassis, increase the vehicle operation life-span, particularly relate to a kind of novel semi-trailer that has automatic synchronization steering mechanism.
