Description
Technical field
The invention is related to a kind of transtainer pure rolling tie rod linkage, belongs to machining technology field.
Background technology
During aircraft portion, general assembly, there is turnover and transportation problem of the spare part in same workshop or different workshops,
The transtainer of different size is needed, wherein most commonly seen with four-wheel trailer.
Trapezium structure is one of primary structure of ground trailer steering system, it make trailer when turning to left and right front-wheel closed
The deflection angle matching of reason so that each wheel makees pure rolling around same instantaneous center of turn on different circumference, to avoid or
Reduce wheel break away, this to extend wheel service life, improve car turn when stability it is extremely important.But it is now actual
Design the tie rod linkage being made and can not all realize and ensure that each wheel can be rolled around same instantaneous center of turn during turning, and all only
The relation of each wheel angle can be made to generally conform to ideal relationship.
Innovation and creation content
The purpose of the invention is to provide a kind of transtainer pure rolling tie rod linkage, turns to transtainer
It is more laborsaving, and improve the service life of wheel.
The invention is implemented by the following technical programs：Transtainer pure rolling tie rod linkage, is one
The individual six bar mechanism formed by a fix bar, a pair of side links, a pair of sliding blocks, a connecting rods, is embodied in, fix bar
It is placed in parallel with connecting rod, a pair of sliding blocks are symmetrically hinged on the two ends of connecting rod and slided along Ackermam track, a pair of side link difference
It is connected between the end of fix bar and sliding block；The side link is welded by turning axle and guide rod, wherein turn the flex point of axle with
The end connection of fix bar, turns the tip of the axis portion and is connected by bearing with front-wheel, guide rod is slided in the hole of sliding block.
The beneficial effect of the invention：The invention is, using Ackerman principle as theoretical foundation, to be passed by analyzing
The sliding reason of the trapezoidal four bar linkage steering engine structure of system, it is proposed that increase sliding block constitutes six-bar linkage structure to realize angle compensation,
Rotated using draw bar drivening rod around fix bar, connecting rod band movable slider is walked along track, sliding block drives side link rotation, front-wheel
It is fixed on connecting rod to obtain correct corner, steering mechanism is realized pure rolling truly.
Brief description of the drawings
Fig. 1 is the structural representation of the invention pure rolling tie rod linkage.
Fig. 2 is Ackermam trajectory diagram when the invention is turned at an angle.
Fig. 3 is the integrally-built front view of the invention transtainer.
Fig. 4 is Fig. 3 top view.
Embodiment
A kind of transtainer as shown in Figures 3 and 4, which employs the pure rolling steering trapezium machine that the invention is provided
Structure, specifically include draw bar 2, car body 1, fix bar 4, side link 5, sliding block 6, connecting rod 7, frame turn to chute 8, front-wheel 12, after
Wheel 3.
The invention pure rolling tie rod linkage is one by a fix bar 4, a pair of side links 5, a pair of sliding blocks
6th, the six bar mechanism of the formation of connecting rod 7, as shown in figure 1, fix bar 4 and connecting rod 7 are placed in parallel, draw bar 2 is respectively with consolidating
Fixed pole 4 and connecting rod 7 are hinged, and a pair of sliding blocks 6 are symmetrical to be hinged on the two ends of connecting rod 7 and turned in frame in chute 8 along Ackermam rail
Mark 13 is slided, and a pair of side links 5 are connected between the end of fix bar 4 and sliding block 6；The side link 5 is by turning the He of axle 11
Guide rod 9 is welded, wherein the flex point for turning axle 11 is connected with the end of fix bar 4, turn the terminal part of axle 11 by bearing 10 with
Front-wheel 12 is connected, and guide rod 9 is slided in the hole of sliding block 6, so as to complete the matching of the instantaneous deflection angle of left and right front-wheel 12.
The frame turns to chute 8 and is screwed onto on car body 1 and uses cylinder finger setting, during adjustment and repairing when convenient for assembly
Resetting.The hinged place of draw bar 2 and connecting rod 7 is provided with slotted hole, to adapt to the change in displacement of hinge during different angles.
The determination method of the Ackermam track 13：1st, pass through after determining two stub centre-to-centre spacing K and front and back wheel wheelspan L
CatiaV5 sketch instruments make Ackermam track, as shown in Fig. 2 lubrication groove and the corner of preceding foreign steamer meet relational expression before making：
ctgA-ctgB=K/L.Rotated using draw bar drivening rod around fix bar, connecting rod band movable slider is walked along track, sliding block drives
Side link rotation, front-wheel are fixed on connecting rod to obtain correct corner.In order to obtain bigger corner, lengthening geometric locus is
Can.
