Description

Technical Field

[0001] The utility model relates to the technical field of automobile suspensions, in particular to a suspension connection mechanism for automobile suspension durability tests. Background Technique

[0002] Automobile suspensions are directly related to vehicle driving safety, handling stability, and riding comfort. Therefore, automobile manufacturers attach great importance to the performance of vehicle suspensions, especially durability; users also have higher and higher requirements for the durability of automobile chassis, especially suspension durability. Based on this, during the process of automobile R & D, trial production, and mass production, automobile manufacturers need to conduct durability tests on suspension components. Since existing automobile suspension durability test devices generally use actuators to directly drive the suspension, the test efficiency is low and the test cycle is increased. Therefore, Patent CN216012746U proposes "a suspension connection mechanism for automobile suspension durability tests". After the suspension connection mechanism is connected to the drive assembly, the suspension can be driven in a road excitation manner. If the installation of suspension components is kept consistent with the suspension installation state on the vehicle at the same time, the test accuracy can be greatly improved, the test efficiency can be improved, the development and test cycle of automobile suspensions can be reduced, and the equipment use cost can be reduced.

[0003] However, in this scheme, the cooperation of the lead screw seat and the lead screw is used to realize the length adjustment of the suspension connection assembly. Since the connecting piece will be repeatedly pulled during the test, the probability of lead screw thread damage will be increased, and the service life of the connection structure will be shortened. Therefore, a suspension connection mechanism for automobile suspension durability tests is proposed. Summary of the Utility Model

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figures 1 to 4 The utility model provides a suspension connection mechanism for automobile suspension durability test: comprising a sensor mounting seat 1 and a spherical joint 2, wherein a tension and pressure sensor 3 is fixedly arranged on the top of the sensor mounting seat 1;

[0027] Referring to Figure 2 Figure 2 , to achieve the purpose of facilitating the replacement of the spherical plain bearing 5, a fixing structure 4 is fixedly provided at the bottom of the sensor mounting seat 1. The fixing structure 4 includes an upper mounting frame 401 and a lower mounting frame 402. The upper mounting frame 401 is fixedly connected to the bottom of the sensor mounting seat 1, and the lower mounting frame 402 is inserted into the upper mounting frame 401. Two slots 404 are provided at the bottom of the upper mounting frame 401. Limit frames 405 are fixedly provided on both sides of the upper mounting frame 401. A plug rod 407 is movably provided on the limit frame 405. A baffle 409 is fixedly provided on the plug rod 407. A first spring 408 is sleeved on the plug rod 407. One end of the first spring 408 abuts against the inner wall of the limit frame 405, and the other end of the first spring 408 abuts against the baffle 409. A plug rod 407 is movably provided on the limit frame 405. A through hole 406 is provided on the inner wall of one side of the slot 404. Two plug plates 403 are fixedly provided at the top of the lower mounting frame 402. The plug plates 403 are adapted to the slots 404. A jack is provided on the plug plate 403. The jack, the through hole 406 and the plug rod 407 are adapted to each other. By pulling the two plug rods 407 outwards simultaneously, when one end of the plug rod 407 disengages from the jack on the plug plate 403, the upper mounting frame 401 and the lower mounting frame 402 can be separated, and the spherical plain bearing 5 can be taken out for separate replacement, which can reduce the use cost of the equipment;

[0028] Referring to Figures 3 to 4 Figures 3 to 4 , to achieve the purpose of adjusting the length, a spherical plain bearing 5 is provided inside the fixing structure 4. A wheel bracket adapter 6 is provided at the top of the spherical joint 2. An adjusting structure 7 is provided between the spherical joint 2 and the load cell 3 and the spherical joint 2. The adjusting structure 7 includes a first mounting cylinder 701 fixedly connected to the spherical joint 2 and a second mounting cylinder 702 fixedly connected to the load cell 3. Arc-shaped grooves are provided inside the first mounting cylinder 701 and the second mounting cylinder 702. A plurality of positioning holes 703 are provided on both of the two arc-shaped grooves. A connecting rod 704 is movably provided inside the first mounting cylinder 701 and the second mounting cylinder 702. Two receiving holes 705 are provided on the connecting rod 704. A second spring 706 is fixedly provided inside the receiving hole 705. A guide plate 707 is fixedly provided between the second spring 706 and the positioning rod 708. The guide plate 707 is movably connected to the receiving hole 705. A positioning rod 708 is fixedly provided at one end of the second spring 706. By pressing the two positioning rods 708 inwards simultaneously, the positioning rod 708 compresses the second spring 706. When one end of the positioning rod 708 retracts into the arc-shaped groove, the first mounting cylinder 701 and the second mounting cylinder 702 can be pulled to move towards or away from each other, realizing the adjustment of the length of the equipment, replacing the method of using a lead screw and a lead screw seat to cooperate to adjust the length, which can effectively prevent the phenomenon of lead screw breakage and slipping, and extend the service life of the equipment.

[0029] Working principle: When it is necessary to adjust the length of the device, press the two positioning rods 708 inward simultaneously. The positioning rod 708 squeezes the second spring 706. After one end of the positioning rod 708 retracts into the arc-shaped groove, the first mounting cylinder 701 and the second mounting cylinder 702 can be pulled to move closer to or away from each other, realizing the adjustment of the device length. This replaces the method of using a lead screw and a lead screw seat to adjust the length, effectively preventing the phenomenon of silk path breakage and slipping, and prolonging the service life of the device. The spherical plain bearing 5 is a consumable part. When the spherical plain bearing 5 is damaged, there is no need to replace the entire connected installation kit. Pull the two insertion rods 407 outward simultaneously. When one end of the insertion rod 407 disengages from the insertion hole on the insertion plate 403, the upper mounting frame 401 and the lower mounting frame 402 can be separated, and the spherical plain bearing 5 can be taken out and replaced separately, which can reduce the use cost of the device.
