Technical Field

The utility model relates to a vehicle turns to technical field, concretely relates to novel turn to drag link structure.

Background

The function of the steering drag link is to transfer the force and motion transferred from the steering rocker arm to the steering trapezoid arm (or knuckle arm). The structure of the steering drag link used on the existing micro-card is that the ball head of the drag link is directly screwed in the link body by threads, the structure is shown in figure 1, the ball head can only be detached from the steering rocker arm when the length of the steering drag link is adjusted, and the adjustment of the length can only be adjusted according to integral multiples of the thread pitch. The time is long, and the adjustment can only be carried out according to integral multiples of the thread pitch, so the adjustment error of the steering drag link is large.

The utility model with the publication number of CN206871174U discloses a steering drag link assembly, which comprises a connecting seat, a first rod body and a second rod body; the top of the bottom plate is fixedly provided with a ball head seat; the top of the ball pin is movably provided with a mounting bolt; one side of the bottom plate is fixedly provided with a connecting arm through welding; the first rod body is embedded and installed on the inner side of the second rod body; the connecting arm and the second rod body are fixedly connected by the connecting seat on the other side through two connecting seat fixing bolts. The utility model discloses the setting of a body of rod and No. two bodies of rod is favorable to the convenience of using, a body of rod and No. two bodies of rod are retractable structure, a body of rod and No. two bodies of rod are the thin form structure of the thick opposite side in one side, and the thin portion outside of a body of rod is provided with the external screw thread, the thin portion inboard of No. two bodies of rod is provided with corresponding internal thread, hold No. two bodies of rod and rotate a body of rod and can make a body of rod remove about, and then increase or reduce the width, the vehicle of the different widths of being convenient for uses.

When the technical scheme is actually adjusted, the adjustment can still be carried out according to integral multiples of the thread pitch, and the adjustment error is larger.

Notice No. CN 207875757U's utility model discloses a turn to drag link structure belongs to the vehicle and turns to the field, can improve the degree of accuracy of adjustment drag link and reduce the man-hour of adjustment drag link. A threaded shaft sleeve (3) is added between the inner part of a rod body (1) of the drag link and a connecting rod at the front end of a drag link ball head (2), and internal threads and external threads are respectively processed inside and outside the threaded shaft sleeve (3); the length of direct accurate adjustment drag link under the circumstances that the drag link was not dismantled, the adjustment precision is high, saves a lot of adjustment time.

This technical scheme is through increasing the screw thread axle sleeve between the connecting rod of the inside front end with the drag link bulb of the body of rod of drag link, though can solve the big problem of current regulation error that turns to the drag link, but its processing and installation degree of difficulty are big.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel turn to drag link structure.

In order to solve the technical problem, the utility model adopts the following technical scheme:

a novel steering drag link structure comprises a steering drag link and steering drag link ball heads arranged at two ends of the steering drag link, wherein the steering drag link is divided into a first rod body and a second rod body, and the first rod body and the second rod body are respectively provided with a threaded hole at the butt joint part; the first rod body and the second rod body are connected through a double-end stud, and thread sections at two ends of the double-end stud are set into threads with opposite rotation directions and are respectively in threaded connection with the corresponding threaded holes of the first rod body and the second rod body.

And an adjusting nut is fixed in the middle of the stud.

And the threaded sections corresponding to the first rod body and the second rod body on the stud are respectively provided with a locking nut in a threaded sleeve mode.

And clamping grooves are respectively formed in the first rod body and the second rod.

The utility model has the advantages that:

the utility model discloses a to turn to the drag link and divide into the first body of rod and the second body of rod to the stud that increases in the middle of the first body of rod and the second body of rod is connected, its simple structure, and processing simple to operate can directly adjust the length of turning to the drag link under the prerequisite of not dismantling to turn to the drag link, and can realize electrodeless regulation, not only save man-hour, adjust the precision again high.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 2 to 4, the novel steering drag link structure of the present invention comprises a steering drag link and a steering drag link ball 3 disposed at two ends of the steering drag link, wherein the steering drag link is divided into a first link body 1 and a second link body 2, and the first link body 1 and the second link body 2 are respectively provided with a threaded hole at the butt joint portion; the first rod body 1 and the second rod body 2 are connected through the double-end stud bolt 4, and thread sections at two ends of the double-end stud bolt 4 are set to be threads with different turning directions and are respectively in threaded connection with threaded holes of the corresponding first rod body 1 and the second rod body 2.

In this embodiment, in order to improve the efficiency of the assembly of the steering drag link, the threaded hole of the first rod body 1 is right-handed. In order to realize the length adjustment of the steering drag link, the threaded hole of the second rod body 2 is a left-hand thread. The threaded sections at the two ends of the stud 4 are respectively matched with the stud. This ensures that the first lever 1 and the second lever 2 move in opposite directions when adjusting the length of the steering drag link, so that the length of the steering drag link can be adjusted without disassembling the ball of the steering drag link.

In order to facilitate adjustment, an adjusting nut is fixed in the middle of the stud bolt 4. Clamping grooves 6 are formed in the first rod body 1 and the second rod body 2 respectively, and a wrench is convenient to clamp.

In this embodiment, the threaded sections corresponding to the first rod body 1 and the second rod body 5 on the stud 4 are respectively threaded with the locking nuts 5, so that the length of the straight pull rod can be adjusted and then locked by the two locking nuts 5.

The working principle of the utility model is as follows:

this practice has increased a screw thread and has revolved to opposite stud 4 in the middle of traditional turn to drag link structure, just so can be under the condition of not dismantling the drag link bulb direct rotation middle stud, alright in order to adjust the length of drag link to can realize electrodeless regulation, both save man-hour, and adjust the precision again high.

After the length of the straight pull rod is adjusted, locking nuts at two ends of the double-end stud are used for tightening.

The above embodiments are only used for illustrating but not limiting the technical solutions of the present invention, and although the present invention is described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that: the present invention may be modified or substituted with equivalents without departing from the spirit and scope of the invention, which should be construed as being limited only by the claims.
