Abstract
The invention provides a pure rolling steering trapezoidal mechanism for a transport trailer. The pure rolling steering trapezoidal mechanism is a six-connection-rod mechanism formed by a fixing rod, a pair of connection frame rods, a pair of sliding blocks and a connection rod. In particular, the fixing rod is parallel to the connection rod, and the sliding blocks are symmetrically hinged to the two ends of the connection rod and slide along the Ackerman locus; the connection frame rods are connected between the ends of the fixing rod and the sliding blocks respectively and formed by welding turning shafts and guide rods. The turning points of the turning shafts are connected with the ends of the fixing rod. The tail ends of the turning shafts are connected with a front wheel through supports. The guide rods slide in holes in the sliding blocks. According to the pure rolling steering trapezoidal mechanism, an Ackerman principle serves as a theoretical basis, angle compensation is achieved through the six-connection-rod structure additionally provided with the sliding blocks, a traction rod is adopted to drive the connection rod to rotate around the fixing rod, the connection rod drives the sliding blocks to walk along the locus, the sliding blocks drive the connection frame rods to rotate, and the front wheel is fixed to the connection rod so as to obtain the right turning angle, so that the steering mechanism can achieve pure rolling in a real sense.
Description
Technical field
The invention relates to a kind of transtainer pure rolling tie rod linkage, belongs to Machining Technology field.
Background technology
In aircraft portion, general assembly process, there is the turnover of spare part in same workshop or different workshop and transportation problem, need the transtainer of different size, wherein common with four-wheel trailer.
Trapezium structure is one of keystone configuration of ground trailer steering system, when it makes trailer turn to, left and right front-wheel obtains rational angle of inclination coupling, thus make each wheel circumferentially make pure rolling around same instantaneous center of turn different, break away to avoid or to reduce wheel, stability when this service life to prolongation wheel, raising car are turned is extremely important.But the tie rod linkage that actual design is made now all cannot realize ensureing that each wheel can roll around same instantaneous center of turn when turning, and the relation of each wheel angle all can only be made to meet ideal relationship substantially.
Innovation and creation content
The object of the invention is to provide a kind of transtainer pure rolling tie rod linkage, transtainer is turned to more laborsaving, and improves the service life of wheel.
The invention is implemented by the following technical programs: transtainer pure rolling tie rod linkage, it is a six bar mechanism formed by a fixed link, a pair side link, a pair slide block, a connecting rod, be embodied in, fixed link placement parallel with connecting rod, a pair slide block symmetry is hinged on the two ends of connecting rod and slides along Ackermam track, and a pair side link is connected between the end of fixed link and slide block; Described side link is by turning axle and guide rod is welded, and the end of the flex point and fixed link that wherein turn axle is connected, and turn the tip of the axis portion and be connected with front-wheel by bearing, guide rod slides in the hole of slide block.
The beneficial effect of the invention: the invention is using Ackerman principle as theoretical foundation, by the slippage reason of the trapezoidal four bar linkage steering engine structure of analysis conventional, propose and increase slide block composition six-bar linkage structure to realize angle compensation, utilize that draw bar drivening rod rotates around fixed link, connecting rod band movable slider drives along track walking, slide block that side link rotates, front-wheel to be fixed on connecting rod to obtain correct corner, enable the pure rolling that steering hardware realizes truly.

Detailed description of the invention
A kind of transtainer as shown in Figures 3 and 4, which employs the pure rolling tie rod linkage that the invention provides, and specifically comprises draw bar 2, car body 1, fixed link 4, side link 5, slide block 6, connecting rod 7, frame turn to chute 8, front-wheel 12, trailing wheel 3.
The invention pure rolling tie rod linkage be one by a fixed link 4, a pair side link 5, a pair slide block, 6, six bar mechanism that connecting rod 7 is formed, as shown in Figure 1, fixed link 4 placement parallel with connecting rod 7, draw bar 2 respectively with fixed link 4 and connecting rod 7 hinged, slide along Ackermam track 13 in the two ends turning in chute 8 in frame that a pair slide block 6 symmetry is hinged on connecting rod 7, a pair side link 5 is connected between the end of fixed link 4 and slide block 6; Described side link 5 is by turning axle 11 and guide rod 9 is welded, the flex point wherein turning axle 11 is connected with the end of fixed link 4, the terminal part turning axle 11 is connected with front-wheel 12 by bearing 10, and guide rod 9 slides in the hole of slide block 6, thus completes the coupling of the instantaneous angle of inclination of left and right front-wheel 12.
Described frame turns to chute 8 to be screwed onto on car body 1 and with straight pin location, adjustment time convenient for assembly and resetting when repairing.Draw bar 2 has slotted hole with the hinged place of connecting rod 7, the change in displacement of hinge during to adapt to different angles.
The defining method of described Ackermam track 13: make Ackermam track by CatiaV5 sketch instrument after 1, determining two stub width between centers K and front and back wheel wheelspan L, as shown in Figure 2, in before making, wheel meets relational expression with the corner of front foreign steamer: ctgA-ctgB=K/L.Draw bar drivening rod is utilized to be fixed on connecting rod to obtain correct corner along track walking, the rotation of slide block drive side link, front-wheel around fixed link rotation, connecting rod band movable slider.In order to obtain larger corner, lengthen geometric locus.
