Description

Technical Field

[0001] The utility model relates to the technical field of thrust rod deflection experiments, in particular to a heavy truck suspension thrust rod deflection experiment device. Background Art

[0002] V-type thrust rods play a crucial role on trucks, preventing not only fore-aft and aft shifting of the center and rear axles but also side-to-side shifting. During production, Sinotruk successfully developed a V-type thrust rod for trucks by overcoming the two major challenges of machining the upper ball seat and heat-pressing the connection. These rods are typically installed on the center and rear axles of trucks in pairs, with one end hinged to the vehicle frame via a spherical pin and the other mounted on the axle via a spherical bearing. Their primary function is to stabilize the axle and maintain stability. Therefore, V-type thrust rods are crucial suspension components, carrying longitudinal and lateral forces and providing guidance. To enhance vehicle comfort, they require a certain degree of elasticity. The ball pin portion of a V-type thrust rod is one of the components with the highest failure rates, primarily due to dislodged ball pins, broken ball pin seats, and worn and loose ball joints. Therefore, after production, V-type thrust rods undergo durability testing to ensure quality. Utility Model Content

[0024] Example 1:

[0025] Please combine Figures 1 to 4 As shown, the utility model provides a heavy truck suspension thrust rod deflection test device, including a base plate 13, the upper side wall of the base plate 13 is fixedly connected to the tail end limit plate 2 and the front end limit plate 6, the tail end limit plate 2 and the front end limit plate 6 are respectively located at the two ends of the base plate 13, the base plate 13 is connected to the oil cylinder 16 through the lifting pair 5, one end of the oil cylinder 16 is provided with an oil cylinder piston rod 15, one end of the oil cylinder piston rod 15 is provided with a motion pair bracket 18, one end of the motion pair bracket 18 is connected to the guide wheel 1, and the guide wheel 1 slides on It is connected to a support frame 14, on which a V-shaped thrust rod 4 is provided, a lifting frame 3 is provided on the tail end limit plate 2, an oil inlet pipeline 11 and an oil return pipeline 10 are fixedly connected to the oil cylinder 16, and an oil tank 17 is provided at one end of the oil inlet pipeline 11 and the oil return pipeline 10, and optical sensors are provided on the V-shaped thrust rod 4 and the cylinder piston rod 15, one of the optical sensors is connected to the V-shaped thrust rod 4 by magnetic attraction, and the other optical sensor is fixedly connected to the cylinder piston rod 15 by a fixed manner.

[0026] When in use, clamp the V-shaped thrust rod 4 on the support frame 14, then slide the support frame 14 left and right, adjust the distance between the support frame 14 and the guide wheel 1, so that one end of the V-shaped thrust rod 4 is in close contact with the guide wheel 1, and then fix and lock the support frame 14 with the anchor bolt 12. A hydraulic pump is provided in the oil tank 17. The hydraulic pump sucks the oil in the oil tank 17 out from the inside, and delivers it to the oil inlet of the oil cylinder 16 through the oil inlet line 11, and flows into the cylinder cavity of the oil cylinder 16, so that the cylinder piston rod 15 moves outward. When the cylinder piston rod 15 needs to retract, the oil in the cylinder 16 flows back to the oil tank 17 through the return oil line 10, is sucked again, and is recycled. The cylinder piston rod 15 performs reciprocating motion Movement, wherein the first time needs to adjust the yaw angle of the V-type thrust rod 4 to the required angle, set the torque used when the yaw angle is reached, and repeat the cycle. The computer records the yaw angle of each operation and the torque required for each push. When the cylinder piston rod 15 moves left and right, the guide wheel 1 moves back and forth, thereby moving the V-type thrust rod 4, thereby performing a yaw motion. The optical sensors on the V-type thrust rod 4 and the cylinder piston rod 15 can record the displacement of the cylinder piston rod 15 and the number of swings of the V-type thrust rod 4, and transmit this information to the computer for recording and display. The optical sensor on the V-type thrust rod 4 is installed by magnetic attraction, which is convenient for installation on different test V-type thrust rods 4.

[0027] Based on the first embodiment, the solution in the first embodiment is further detailed in combination with the following specific working method, which is described below for details.

[0028] Example 2:

[0029] The lifting pair 5 includes a U-shaped frame 51, which is fixedly connected to the upper side wall of the bottom plate 13. A rotating rod 52 is rotatably connected to the U-shaped frame 51. The bottom end of the rotating rod 52 is fixedly connected to a fixing ring 53. The oil cylinder 16 is fixedly connected to the inner side wall of the fixing ring 53. The upper end of the rotating rod 52 is fixedly connected to a second turning handle 54.

[0030] By rotating the handle 54 clockwise and counterclockwise, the rotating rod 52 is rotated clockwise and counterclockwise, and the fixing ring 53 below is rotated accordingly, so that the direction of the fixing ring 53 can be adjusted, so that the oil cylinder 16 and the moving sub-bracket 18 are horizontally parallel, with no tilt angle between the two, further facilitating the progress of the experiment.

[0031] The kinematic sub-bracket 18 includes two U-shaped frames 181, which are fixedly connected to the upper side wall of the base plate 13. A fixed rod 182 is fixedly connected to each of the U-shaped frames 181. A sliding plate 183 is slidably connected to each of the fixed rods 182. A connecting plate 184 and a hinge 185 are fixedly connected to the side walls of the sliding plate 183. The hinge 185 is connected to the cylinder piston rod 15. The guide wheel 1 is provided on the connecting plate 184.

[0032] When the cylinder piston rod 15 moves back and forth, it brings the sliding plate 183 to move back and forth on the two fixed rods 182, thereby causing the guide wheel 1 installed on the connecting plate 184 to move back and forth. The reciprocating movement of the cylinder piston rod 15 will cause the guide wheel 1 to move back and forth, thereby causing the V-shaped thrust rod 4 to swing back and forth. By using the equipment to push and pull horizontally and with the help of the lever principle, the push and pull force is changed into the swing angle value, thereby realizing the swing angle experiment.

[0033] The lifting frame 3 includes a mounting plate 31, which is fixedly connected to the side wall of the tail end stop plate 2. A threaded rod 32 is rotatably connected to the mounting plate 31, and a movable plate 33 is threadedly connected to the threaded rod 32. The movable plate 33 contacts the tail end stop plate 2, and a handle 34 is fixedly connected to the upper end of the threaded rod 32.

[0034] The clockwise and counterclockwise rotation of the handle 34 can cause the threaded rod 32 to rotate. Since the movable plate 33 is in close contact with the tail end limit plate 2, the movable plate 33 will not rotate with the threaded rod 32. Therefore, the movable plate 33 will move up and down when the threaded rod 32 rotates. The main function is to adjust the support of the push-pull cycle operation of the horizontal thrust rod.

[0035] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
