Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, in particular to a steering system tie rod assembly. Background Art

[0002] The car's tightening rod is used to connect the car's front wheel steering knuckle and steering gear, so that when the steering wheel is turned, the front wheel can swing from one side to the other. The tightening rod is a rod connecting the steering gear arm and the left arm of the steering knuckle. After the steering gear power is transmitted to the steering knuckle, the wheel can be controlled.

[0003] The steering lateral and straight tie rods of the prior art automobile tie rod assembly are connected by a middle steel pipe and a ball hinge joint assembly through threads, and the two ends are fastened by clamping clamps, bolts, and nuts. Due to the needs of the whole vehicle layout and specific design, the middle steel pipe is usually made into different shapes according to the space size. When assembling a new car or user maintenance, the length of the tie rod needs to be adjusted to a suitable size, and the two side tie rods are connected to other parts of the car in the form of ball hinges. If the length needs to be fine-tuned, the nuts on both sides cannot be locked, so there is a problem that the axial position of the two side tie rods changes when adjusting the length. In addition, when adjusting the length, the clamps at both ends need to be loosened to adjust. Since the middle steel pipe has a large drop, a complex shape, and a small space, the steering tie rod needs to be removed from the steering rocker arm or the steering knuckle arm for adjustment, which has a large workload and cumbersome operation, and low production efficiency, resulting in difficulty in adjusting the total length of the steering lateral and straight tie rods of the automobile tie rod assembly.
