Description

Technical Field

[0001] The utility model application relates to the technical field of steering tie rods, in particular to a telescopic and adjustable steering tie rod. Background Art

[0002] The steering tie rod is an important part of the automobile steering mechanism and is generally divided into two categories, namely, the steering straight tie rod and the steering transverse tie rod. The steering straight tie rod is responsible for transmitting the movement of the steering rocker arm to the steering knuckle arm, and the steering transverse tie rod is the bottom edge of the steering trapezoidal mechanism. It is a key component to ensure the correct movement relationship between the left and right steering wheels. It directly affects the stability of automobile handling, the safety of operation and the service life of the tires. It is also very common in construction machinery applications.

[0003] Currently, most steering tie rods use threads to adjust the overall length of the tie rods on both sides. The tie rods need to be rotated during adjustment. The tie rods are also rotationally connected to the steering rocker arm and the steering knuckle arm. However, since the rotation direction is inconsistent with the rotation direction when the tie rods are adjusted in length through threads, after the tie rods are rotated to adjust the length, both ends cannot meet the installation requirements at the same time. Summary of the invention

[0008] Furthermore, an insert block is fixed to one end of the straight pull rod 2 close to the straight pull rod 1, and the insert block is inserted into the straight pull rod 1, a movable plate is symmetrically slidably arranged inside the insert block, and a limit block is fixed on the outer side of the movable plate extending to one end inside the straight pull rod 1, and limit grooves cooperating with the limit block are symmetrically provided inside the straight pull rod 1, a number of springs are equidistantly fixed between the two insert blocks, and a pressure block is fixed on the outer side of the end of the insert block away from the limit block, and the pressure blocks extend to the outside of the insert block.

[0009] Furthermore, a plurality of slide bars are equidistantly slidably sleeved inside each of the insert blocks, and the upper and lower ends of the slide bars are fixed on the inner wall of the insert block, and each of the springs is slidably sleeved on the outside of the slide bars.

[0010] Furthermore, a fixed sleeve is threadedly sleeved inside the straight pull rod 1 outside the plug block, a threaded groove cooperating with the fixed sleeve is opened at one end of the dust cover close to the straight pull rod 1, and a rotating hole cooperating with the fixed sleeve and a slot cooperating with the plug block are opened inside the straight pull rod 1.

[0011] Furthermore, the length of each fixed sleeve extending to the outside of the straight pull rod 1 is less than the length between the pressure block and the straight pull rod 1, and the length of the fixed sleeve is greater than the length between the straight pull rod 1 and the dust cover.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the utility model, through the segmented adjustment structure, there is no need to rotate the tie rod 1 and the railing 2 during adjustment, so that the connecting sleeves at the ends of the tie rods are conveniently connected to the steering rocker arm or the steering knuckle arm, which solves the problem that the existing telescopic adjustable steering tie rods are easily affected in the installation connection of the tie rod ends when adjusting the length, and improves the practicality of the steering tie rods.

[0014] 2. In the utility model, by means of the detachable straight tie rod 1 and the straight tie rod 2, when the dust cover is damaged, the damaged dust cover can be removed and replaced without disassembling the steering tie rod as a whole. At the same time, the double fixing structure ensures the firmness of the connection between the straight tie rod 1 and the straight tie rod 2 when they are fixed, further improving the convenience of using the steering tie rod.
