[0023] The principles and features of the present utility model are described below with reference to the drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.
[0024] As Figure 1 shown, the steering gear endurance test bench of Embodiment 1 of the present utility model includes a steering gear fixing table 1. Both the left and right sides of the steering gear fixing table 1 are fixedly connected with support components 2. Electric push rods 4 are fixedly installed on both the left and right sides of the bottom of the steering gear fixing table 1.
[0025] The steering gear fixing table 1 is the installation area of the steering gear. The moving direction of the steering gear is left and right. First, adjust the position of the test component 3 according to the length of the steering gear. At the same time, start the two electric push rods 4 at the bottom of the steering gear fixing table 1. The electric push rods 4 extend outwards or retract inwards according to the length of the steering gear, thereby driving the test component 3 to move linearly in the support component 2. When the test components 3 on both sides are located on both sides of the steering gear, turn off the electric push rods 4. During the steering process of the steering gear, it will repeatedly contact the test component 3. During the contact process, the test component 3 can conduct an endurance test on it and transmit and save the test data.
[0026] As Figure 2 shown, the steering gear endurance test bench of Embodiment 2 of the present utility model, on the basis of Embodiment 1, the support component 2 includes a side guard plate 20, a support plate 21 and a limiting rod 22. The bottom of the inner side of the side guard plate 20 is fixedly connected with the support plate 21. Two limiting rods 22 are fixedly connected between the side guard plate 20 and the steering gear fixing table 1. The test component 3 is slidably connected to the outside of the limiting rod 22. The support component 2 has the functions of support, limitation and protection, and can improve the stability and accuracy of the test component 3 during the moving adjustment process. Among them, the side guard plate 20 is in the shape of "[", and the side guard plate 20 and the support plate 21 are an integral body. The support plate 21 and the side guard plate 20 respectively protect the bottom and both sides of the test component 3, and can limit the movement of the test component 3 to prevent it from being affected by external forces. A transverse opening is provided in the middle of the support plate 21. The function of the transverse opening is to facilitate the connection between the test component 3 and the electric push rod 4.
[0027] As Figure 3As shown in the figure, for the steering gear durability test bench in Embodiment 3 of the present utility model, on the basis of Embodiment 1, the test assembly 3 includes a movable plate 30, a fixing member 31, a resistance regulator 32, a reset device 33, a contact plate 34, a test rod 35, a distance measuring sensor 36 and a connecting plate 37. An installation hole is provided on the movable plate 30, and a fixing member 31 is fixedly installed inside the installation hole. One side of the fixing member 31 is fixedly installed with a resistance regulator 32. Four reset devices 33 are fixedly connected to the side of the movable plate 30 away from the resistance regulator 32 at equal intervals. One end of the reset device 33 away from the movable plate 30 is fixedly connected to the contact plate 34. A test rod 35 is fixedly connected to the side of the contact plate 34 close to the movable plate 30. One end of the test rod 35 away from the contact plate 34 penetrates through the movable plate 30 and extends into the resistance regulator 32. A distance measuring sensor 36 is fixedly installed on the side of the contact plate 34 close to the movable plate 30. The bottom of the movable plate 30 is fixedly connected to a connecting plate 37. The connecting plate 37 is in contact with the inner side of the horizontal opening provided on the support plate 21. The contact plate 34 is in direct contact with the steering gear. During the test, the contact plate 34 will be pushed. The distance measuring sensor 36 will record the movement data when the contact plate 34 is pushed, so as to judge the number of turns or the number of operations of the steering gear. Moreover, bilateral synchronous testing is adopted, which is convenient for data comparison or data verification. After the contact plate 34 on one side is separated from the steering gear, the reset device 33 will reset the contact plate 34, which is convenient for repeated testing until the durability test is completed. The resistance regulator 32 can adjust the resistance size, so that the contact plate 34 connected to the test rod 35 is subjected to different resistances when being pushed by the steering gear, making the test more realistic. There are two limiting holes provided at the bottom of the movable plate 30. The limiting holes are sleeved with the limiting rods 22. After the limiting holes and the limiting rods 22 are sleeved, the movement of the movable plate 30 is further restricted, avoiding tilting during its movement and making the data detected by the distance measuring sensor 36 more accurate. A cushion is attached to the outer surface of the side of the contact plate 34 away from the test rod 35. The cushion is circular, reducing damage to the contact plate 34 and improving its service life. The connecting plate 37 is fixedly connected to the telescopic end of the electric push rod 4.
[0028] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
