Steering machine outer tie rod-2.8T
Steering rod is an important part in the steering mechanism of the car, which directly affects the stability of the car's handling, the safety of running and the service life of the tire. Steering rods are divided into two categories, namely, steering straight rods and steering tie rods. The steering tie rod is responsible for transmitting the movement of the steering rocker arm to the steering knuckle arm; the steering tie rod is the bottom edge of the steering trapezoidal mechanism, and is a key component to ensure the correct kinematic relationship between the left and right steering wheels.
Steering tie rod is an important part in the steering mechanism of the car. It plays a role in transmitting motion in the steering system, and directly affects the stability of the car's handling, the safety of running and the service life of the tire. Steering rods are divided into two categories, namely, steering straight rods and steering tie rods. The steering tie rod is responsible for transmitting the movement of the steering rocker arm to the steering knuckle arm; the steering tie rod is the bottom edge of the steering trapezoidal mechanism, and is a key component to ensure the correct kinematic relationship between the left and right steering wheels.
Classification and function
Steering tie rod. The steering tie rod is the transmission rod between the steering rocker arm and the steering knuckle arm; the steering tie rod is the bottom edge of the steering trapezoidal mechanism.
The steering tie rod is responsible for transmitting the movement of the steering rocker arm to the steering knuckle arm; the steering tie rod is the bottom edge of the steering trapezoidal mechanism, and is a key component to ensure the correct kinematic relationship between the left and right steering wheels.
Structure and Principle
The automobile steering tie rod is mainly composed of: ball joint assembly, nut, tie rod assembly, left telescopic rubber sleeve, right telescopic rubber sleeve, self-tightening spring, etc., as shown in Figure 1.
steering rod
There are mainly two structures of the straight tie rod: one has the ability to ease the reverse impact, and the other has no such ability. In order to ease the reverse impact, a compression spring is arranged at the head of the straight tie rod, and the axis of the spring is connected to the straight pull rod. The opposite direction is consistent, as it needs to bear the force along the axis of the straight tie rod, and can eliminate the gap between the spherical part of the ball stud pin and the ball stud bowl due to wear. For the second structure, the priority is the rigidity of the connection rather than the ability to cushion the impact. This structure is characterized by the axis of the compression spring located under the ball stud in the same direction as the ball stud. Compared with the former, the compression The force condition of the tight spring is improved, and it is only used to eliminate the gap caused by the wear of the spherical part.
tie rod
The steering tie rod in the non-independent suspension is different in structure from the steering tie rod in the independent suspension.
(1) Steering tie rod in non-independent suspension
The steering tie rod in the non-independent suspension of a certain car. The steering tie rod is composed of a tie rod body 2 and a tie rod joint screwed at both ends, and the joints at both ends have the same structure. The afterbody of ball stud pin 14 in the figure is connected with trapezoidal arm, and upper and lower ball stud seat 9 is made of polyoxymethylene, has good wear resistance, guarantees that two ball stud seats are in close contact with the ball head, and acts as a buffer, Its preload is adjusted by a screw plug.
The two joints are connected with the tie-rod body by threads, and the threaded parts of the joints have cutouts, so they are elastic. The joints are screwed onto the tie-rod body and clamped with clamping bolts. One end of the thread at both ends of the tie rod is right-handed, and the other end is left-handed. Therefore, after the clamping bolt is loosened, the total length of the tie rod can be changed by turning the tie rod body, thereby adjusting the toe-in of the steering wheel.
