Steering rod is an important part of the steering mechanism of a car, which directly affects the stability of the car’s handling, the safety of operation and the service life of the tire. Steering rods are divided into 2 types, namely steering straight rods and steering cross rods. The steering straight rod is responsible for transmitting the movement of the steering rocker arm to the knuckle arm; the steering tie rod is the bottom edge of the steering trapezoidal mechanism, and it is a key component to ensure that the right and left steering wheels have a correct motion relationship.
The automobile steering rod is mainly composed of: ball joint assembly, nut, tie rod assembly, left telescopic rubber sleeve, right telescopic rubber sleeve, self-tightening spring, etc.
Steering rods are divided into 2 types, namely steering straight rods and steering cross rods. The steering straight rod is the transmission lever between the steering rocker arm and the steering knuckle arm; the steering cross rod is the bottom edge of the steering trapezoidal mechanism.

Steering Straight Rod The structure of the steering straight rod is mainly two types: one has the ability to mitigate reverse impact, and the other does not have this ability. In order to mitigate the reverse impact, a compression spring is provided at the rod end of the straight rod. The spring axis is the same as the straight rod in the opposite direction. As a result, it needs to withstand the force in the direction of the straight rod axis. The gap between bowls due to wear. For the second structure, priority is given to the rigidity of the connection rather than the ability to mitigate the impact. This structure is characterized in that the axis of the compression spring located below the ball pin is the same as the ball pin direction. Compared with the former, the pressure The tension of the tension spring is improved, and it is only used to eliminate the gap caused by wear on the spherical surface.
Tie rod The tie rods in a non-independent suspension are structurally different from the tie rods in an independent suspension. (1) Steering tie rod in non-independent suspension The steering tie rod is composed of a tie rod body and a tie rod joint that is screwed on both ends. The joint structure at both ends is the same. The two joints are connected to the tie rod body by threads, and the thread part of the joint has a cutout, so it is elastic. The joint is screwed onto the tie rod body and clamped with a clamping bolt. One end of the thread at both ends of the tie rod is right-handed and one end is left-handed. Therefore, after loosening the clamping bolt, the total length of the tie rod can be changed by turning the tie rod body, thereby adjusting the toe of the steering wheel. (2) Steering tie rods in independent suspension In order to adapt to the independent suspension, the steering trapezoid must also be divided into two or three sections.
