Abstract
The utility model discloses a pre-pull rod following steering device, comprising a draw bar, a deflecting plate and two following steering axle shafts that are installed on a car frame; one end of the draw bar is connected with the car frame and the other end of the draw bar is connected with one end of the deflecting plate through an anterior longitudinal pull bar; the symmetric center of the deflecting plate is connected with the car frame; the following steering axle shafts are installed on the car frame, wherein one following steering axle shaft is connected with the other end of the deflecting plate through a posterior longitudinal pull bar, and the two following steering axle shafts are connected through a steering tie rod. A full trailer can steer and align flexibly along with the steering of main vehicle so as to greatly reduce the turning radius of the whole vehicle and simultaneously avoid abnormal abrasion of tire largely and reduce the replacing frequency of tire, thereby solving the problems of large turning radius of rigid axle shaft and various abrasion of tire.
Description
Technical field
The utility model relates to a kind of fully-trailed trailer, is applied to a kind of preposition rod-pulling type follower steering device that can follow main car working direction wheel certain angle on the preceding supporting bridge of fully-trailed trailer specifically, belongs to automotive field.
Background technology
The antero posterior axis of tradition independent trailer is a rigid shaft all, and tire serious wear and turn radius are big during turning, and the scope that causes independent trailer to be used is narrower, and present domestic recoverable amount is less.The application of abroad little in fact tonnage independent trailer is very extensive, is mainly used in caravan, special equipment transport trolley, load-carrying vehicle etc.Development along with the domestic automobile industry, especially the lifting of engine power and road construction is perfect, the demand two of the independent trailer of special purpose is more and more higher, and the present invention is applied to the independent trailer front axle, has eliminated two big inferior positions of puzzlement independent trailer development from structure.
The utility model content
At the deficiency that prior art exists, technical problem to be solved in the utility model is, a kind of preposition rod-pulling type follower steering device is provided, and can solve to join rigidity axletree independent trailer tire serious wear and the big problem of turn radius when turning.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of preposition rod-pulling type follower steering device, comprise the draw bar, deflecting plate and the two follow-up steering axletrees that are arranged on the vehicle frame, described draw bar one end connects to ground, the other end is connected with deflecting plate one end by preceding longitudinal tie, deflecting plate center of symmetry place connects to ground, the follow-up steering axletree is arranged on the vehicle frame, wherein a follow-up steering axletree is connected with the deflecting plate other end by the back longitudinal tie, and described two follow-up steering axletrees connect by tierod.
Above-mentioned preposition rod-pulling type follower steering device, described forward and backward longitudinal tie and tierod comprise the pull bar body of rod and rod head, and the two connects by the internal and external threads cover, and the pull bar body of rod that matches with the internal and external threads cover is provided with clip.
Above-mentioned preposition rod-pulling type follower steering device, described deflecting plate is symmetrical fusiformis structure, the center of symmetry place is provided with a rotating hole, described deflecting plate is connected with permanent seat on being welded on vehicle frame by bolt, two ends at deflecting plate respectively are provided with a through hole, pass through bolted connection with forward and backward longitudinal tie respectively.
Above-mentioned preposition rod-pulling type follower steering device, described tierod two ends are connected with both sides follow-up steering axletree by bolt respectively.
The advantage of a kind of preposition rod-pulling type follower steering device of the utility model is, overturned the Design Mode of traditional independent trailer axletree, the independent trailer draw bar is connected with the steerable axle by pull bar, realized that independent trailer follows main car and turn to, independent trailer can turn to main car and turn to flexibly and just return, reduced the car load turn radius greatly, the crossing ability of car load is strengthened, avoided simultaneously the inordinate wear of tire to a great extent, reduced the replacing frequency of tire, rigidity axletree turn radius is big, the problem of severe wear tire thereby solved.

The specific embodiment
Below in conjunction with drawings and the specific embodiments the utility model is described in further detail;
As shown in Figure 1, 2, a kind of preposition rod-pulling type follower steering device of the utility model, comprise the draw bar 1, deflecting plate 4 and the two follow-up steering axletrees 5 that are arranged on the vehicle frame, draw bar 1 one ends connect to ground, the other end is connected with deflecting plate 4 one ends by preceding longitudinal tie 2, deflecting plate 4 center of symmetry places connect to ground, follow-up steering axletree 5 is arranged on the vehicle frame, wherein a follow-up steering axletree 5 is connected with deflecting plate 4 other ends by back longitudinal tie 3, and described two follow-up steering axletrees 5 connect by tierod 6.
As shown in Figure 4, be the structural representation of preceding longitudinal tie 2, back longitudinal tie 3 and tierod 6, it comprises the pull bar body of rod 10 and rod head 7, and the two connects by internal and external threads cover 8, be provided with clip 9 with the internal and external threads cover 8 pull bar bodies of rod 10 that match, clip 9 is fastening by bolt 14.When realizing the different vehicle of coupling or load change need adjust longitudinal tie when big the tire initial position is ajusted, two longitudinal ties adopt the structure that has increased internal and external threads cover 8 between the screw thread fit of the traditional rod head 7 and the pull bar body of rod 10 in this device, it is adjustable its length that the longitudinal tie that has solved the band drop need not dismounting, has saved Unit Installation, adjustment time greatly.
As shown in Figure 5, structural representation for deflecting plate 4, this deflecting plate 4 is symmetrical fusiformis structure, the center of symmetry place is provided with a rotating hole 11, deflecting plate 4 is by being installed in the bolt in the rotating hole 11, be connected with the permanent seat 13 on being welded on frame beam, a through hole 12 respectively be set, pass through bolted connection with preceding longitudinal tie 2, back longitudinal tie 3 respectively at the two ends of deflecting plate 4.
As shown in Figure 3, structural representation for the follow-up steering axletree 5 of automobile, described tierod 6 two ends are connected with the follow-up steering axletree 5 of both sides by bolt respectively, formation is rotationally connected, automobile passes through the rotation of the follow-up steering axletree 5 of a side when turning, by the effect drive opposite side wheel steering of tierod 6.
During automobile turning, main car turns to drive draw bar 1 to turn an angle, this rotating torque is delivered on the deflecting plate 4 by preceding longitudinal tie 2 immediately, be delivered on the longitudinal tie 3 of back with this rotational angle amplification or after dwindling by deflecting plate 4, little in the effect of rotating push-pull effort, the tierod 6 of follow-up steering axletree 5 drives inside and outside wheel flutter around the different angle of stub deflection, and this moment, the four-wheel line of centers of independent trailer met at a bit, avoid the sliding phenomenon of dragging of tire, realize the independent trailer follow-up steering.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
