Problems solved by technology
Due to the complex force on the steering rod, it has to bear the swing, rotation and axial force, and it is difficult to completely simulate it. There is no electro-hydraulic servo fatigue testing machine that can completely simulate the actual working conditions in China.
Domestic steering rod manufacturers and R&D institutions basically adopt the scheme of separately simulating the force in each direction, which will lead to a large deviation between the test and the actual working conditions, resulting in inaccurate test data

Embodiment Construction
[0029] Accompanying drawing is the specific embodiment of the present invention. Such as Figure 1 to Figure 5 As shown, this electro-hydraulic servo fatigue testing machine includes a swing mechanism, a rotation mechanism and a horizontal loading mechanism installed on the frame 1, and the swing mechanism and the rotation mechanism are connected by a connecting rod 2, wherein:
[0030] The swing mechanism comprises a swing cylinder 3 with a vertically arranged main shaft. A swing arm 4 is fixed on the upper end of the swing cylinder 3 and the connecting rod 2 respectively. The arms 4 form a parallelogram;
[0031] The rotating mechanism includes a double output shaft swing cylinder 6 with the output shaft 61 horizontally arranged. The double output shaft swing cylinder 6 is located in the frame 7, and its two output shafts 61 protrude from the frame 7, and the lower end of the coupling rod 2 is fixedly connected with the frame 7. , the two output shafts 61 of the double out...

The invention relates to the field of performance testing of materials and components, and particularly discloses an electro-hydraulic servo fatigue testing machine. The electro-hydraulic servo fatigue testing machine comprises a swinging mechanism, a rotary mechanism and a horizontal loading mechanism, wherein the swinging mechanism is connected with the rotary mechanism through a connecting link and comprises a swinging cylinder, the upper ends of the swinging cylinder and the connecting link are each provided with a swinging arm, the two ends of each swinging arm are each hinged to a swinging rod, and the two swinging rods and the two swinging arms form a parallelogram; the horizontal loading mechanism comprises a linear actuator and the swinging rods. The electro-hydraulic servo fatigue testing machine can completely simulate the actual work conditions of a steering pull rod, rotary force, swinging force and axial force can be simultaneously applied to the steering pull rod, and a load spectrum can be also input for coordinated control. Meanwhile, two samples are tested at the same time, so that the problem that force components in various directions interfere in one another in the stressed process is well resolved.
Description
[0001] (1) Technical field [0002] The invention relates to the field of material and component performance testing, in particular to an electro-hydraulic servo fatigue testing machine. [0003] (2) Background technology [0004] The steering rod is used to connect the steering knuckle and the steering gear of the front wheel of the car, so that when the steering wheel is turned, the front wheel can be swung from one side to the other. Steering tie rods are divided into steering straight rods and steering tie rods. The steering tie rod is a part of the steering trapezoid of the car, which plays the role of steering force transmission. The steering straight rod is a rod connecting the steering arm and the left arm of the steering knuckle. After the power of the steering machine is transmitted to the steering knuckle, the wheels can be controlled. [0005] The ball joint assembly is a key part of the steering rod, and fatigue damage is the main damage form of this part. [00...
