[0002] The steering tie rod is an important part of the automobile steering mechanism, which directly affects the stability of automobile handling, the safety of operation and the service life of tires. The steering tie rod is divided into two categories, namely the steering tie rod and the steering tie rod. The steering tie rod is responsible for transmitting the movement of the steering rocker arm to the steering knuckle arm, while the steering tie rod is the bottom edge of the steering trapezoidal mechanism and is a key component to ensure the correct movement relationship between the left and right steering wheels.
[0003] The steering rod is a car safety part, so it needs to undergo a bench durability test. Generally, hydraulic equipment is used to simulate the actual vehicle operation status. The steering rod is installed on this equipment, and the steering rod is made to rotate, swing and withstand a certain loading force. Generally, it is swung 1 million times to examine the long-term reliability of the product.
[0004] However, the swing beam of a conventional endurance testing machine is fixed and cannot be adjusted, and the lengths of the inner tie rods of different steering tie rod products vary greatly, which cannot completely match the swing beam of the environmental endurance testing machine tooling and has poor applicability. Therefore, it is often necessary to shorten the I BJ rod and then process the external thread. At the same time, the test after the I BJ is shortened deviates from the actual working conditions, which may also affect the authenticity of the test results. Utility Model Content
