Abstract

The utility model relates to a steering mechanism for making a trailer change directions, which solves the problems that the steering fulcrum of the existing trailer changes with the change of steering angles, safety factors are small, and reliability is bad. The utility model is composed of a drawing rod, a steering transverse pull rod, a front beam and sheep horn shafts, wherein, the steering transverse pull rod is parallel to the front beam. The drawing rod is vertical to the front beam. The sheep horn shafts are arranged on both ends of the front beam. The utility model and a trailer body are integral, and the utility model has the advantage of strong reliability. The adoption of wheel positioning steering improves the safety factors. The steering mechanism can be widely used in various trailers.

Description

The trailer steering hardware

The utility model relates to the device that makes the vehicle change of direction, exactly is the trailer steering hardware.

Turning to of existing trailer adopts a no fix to turn to, and steering angle is big more, and the distance between two fulcrums is just more little, and safety factor is relatively more little.And the steering hardware of trailer and Trailer type frame for use in vehicle two parts are split type, and when being subjected to external force, two parts easily break away from, and occur dangerous.

The purpose of this utility model is: it is an integral body that a kind of steering hardware and vehicle frame are provided, and the location turns to the trailer steering hardware that the distance between two fulcrums does not change with steering angle.

The technical solution that realizes above-mentioned purpose is such: the trailer steering hardware, form by stayed pole, tierod, front-axle beam and goat's horn axle, be characterized in: the two ends of front-axle beam are respectively equipped with the goat's horn axle, the goat's horn axle is L-shaped, one end of two goat's horn axles is connected with tierod respectively, the other end of two goat's horn axles is being adorned wheel respectively respectively to abduction on it.Stayed pole is located at and front-axle beam, direction that tierod is vertical, and the one end is connecting tierod and front-axle beam, and its other end is connecting main car.Three place's point of connection are on same straight line on the front-axle beam, and three place's point of connection on the tierod are also on same straight line.

The utlity model has the advantage of following several aspects:

One, its steering hardware is located on the front-axle beam of vehicle frame, forms a whole with vehicle frame, does the time spent being subjected to external force, trailer steering hardware and vehicle frame break-off can not occur, has improved the safe reliability of trailer.

Two, its steering hardware adopts the location of wheel to turn to, and the pivot distance between two wheels can not change with the change of steering angle, has improved the safety factor of trailer.

Three, the reasonable in design of this steering hardware is simple in structure, and fabrication properties is good, and low cost of manufacture can be widely used on various types of trailers and the dolly.

Description of drawings.

Fig. 2 is the A-A cutaway view of Fig. 1,

Fig. 3 is the B-B cutaway view of Fig. 1,

Fig. 4 is the C-C cutaway view of Fig. 3,

Fig. 5 turns to scheme drawing for the utility model.

Below in conjunction with drawings and Examples the utility model is described further.

Be contained in the two ends of front-axle beam 5 by Fig. 1, Fig. 2, visible two the goat's horn axles 4 of Fig. 3, Fig. 4, the goat's horn axle is L-shaped, promptly curve rectangular-shapedly, the two ends of tierod 2 are connected with one side axle head of the goat's horn axle 4 at front-axle beam 5 two ends respectively by pipe link 3, and parallel and front-axle beam 5; The another side axle head abduction of goat's horn axle 4, and adorning wheel.Stayed pole 1 is installed on tierod 2 and the front-axle beam 5, and perpendicular to front-axle beam 5, can do the rotation of 120 degree scopes around the flexible connection point on the front-axle beam 5.The point of connection of the point of connection at two ends and middle part stayed pole 1 is on same straight line on the front-axle beam 5.

Three place's point of connection on the tierod 3 are also on same straight line.The other end of stayed pole 1 is connecting main car.

(see figure 5) when turning to, stayed pole 1 under the traction of main car, give part of a turn partially left, stayed pole 1 drives tierod 3 to left simultaneously, promotes goat's horn axle 4 and rotates, thereby wheel alignment is turned to.

Claims

1, trailer steering hardware comprises stayed pole, tierod, front-axle beam and goat's horn axle, it is characterized in that:

The two ends of front-axle beam are respectively equipped with the goat's horn axle, and the goat's horn axle is L-shaped, and an end of two goat's horn axles is connected with tierod respectively, and the other end of two goat's horn axles is respectively to abduction, and are connected with wheel respectively; One end of stayed pole is connected with the middle part of tierod and front-axle beam respectively, and the other end of stayed pole is connected with main car; On the front-axle beam and tierod on three place's point of connection respectively on same straight line.
