Description

Technical Field

[0001] The present invention relates to the technical field of vehicle suspension systems, and specifically to a connecting device for detecting vehicle suspension struts. Background Technique

[0002] A suspension is the general term for all force transmission connecting devices between the vehicle frame (or integral body) and the axle (or wheels). Its function is to transmit the forces and torques acting between the wheels and the frame, and to buffer the impact force transmitted from the uneven road surface to the frame or body, and reduce the resulting vibration to ensure that the vehicle can drive smoothly. A typical suspension structure consists of elastic elements, guiding mechanisms, shock absorbers, etc. Some structures also have buffer blocks, anti-roll bars, etc. Elastic elements include leaf springs, air springs, coil springs, torsion bar springs, etc. Modern car suspensions mostly use coil springs and torsion bar springs, and some high-class cars use air springs. The performance of the vehicle suspension strut is one of the key performances of the vehicle suspension. During the design and development process of the whole vehicle and the suspension, to verify whether the strut performance meets the product design requirements, it is necessary to detect the performance of the strut such as stiffness, resistance, resistance direction, maximum contour, etc.

[0003] The current common practice is to indirectly verify the strut performance by detecting the components of the strut or to verify the performance by installing it on the vehicle. Mechanical testing equipment such as spring test benches and electronic universal test benches are required to detect the performance of the strut. During the detection process, a connecting device is needed to fix the strut and automatically align the upper part of the strut to make the upper installation center of the strut on the center line connecting the upper and lower test discs of the detection equipment.

[0004] However, the existing connecting device has a relatively complex structure and is rather cumbersome when aligning the strut, thus affecting the detection efficiency of the strut.

[0005] Therefore, we propose a connecting device for detecting vehicle suspension struts. Summary of the Invention

[0006] The purpose of the present invention is to provide a connecting device for detecting vehicle suspension struts to solve the problem in the above background technique that the existing connecting device has a relatively complex structure and is rather cumbersome when aligning the strut, thus affecting the detection efficiency of the strut.

[0007] To achieve the above purpose, the present invention provides the following technical solutions:

[0008] A connecting device for detecting vehicle suspension struts, comprising:

[0009] An upper seat, a central threaded hole is provided at the central position of the upper seat;

[0010] The upper seat is connected to the bottom of the detection device through a central threaded hole in cooperation with a first fixing bolt;

[0011] A pillar upper limit plate is arranged at the bottom of the upper seat. The pillar upper limit plate is provided with a connecting threaded hole, and the pillar upper limit plate is connected with a pillar main body placed at the bottom of the pillar upper limit plate through the connecting threaded hole in cooperation with a second fixing bolt;

[0015] As a further solution of the present invention, a positioning pin is clamped in the limiting hole, and the bottom of the positioning pin is located at the inner bottom of the connecting hole.

[0016] Through the above technical solution, the following technical effects can be achieved: By clamping the positioning pin into the limiting hole and the connecting hole, the alignment of the upper seat, the boss, and the pillar upper limit plate can be quickly completed, and then the alignment of the pillar main body can be quickly completed, and it is promoted that the pillar main body and the detection device are on the same central connection line, improving the alignment speed and detection efficiency of the pillar main body.

[0017] As a further solution of the present invention, a fixing hole communicating with the connecting hole is arranged at the bottom of the pillar upper limit plate, and a fixing threaded hole is arranged at the bottom of the positioning pin;

[0018] A fixing screw is threadedly connected in the fixing hole and the fixing threaded hole.

[0019] Through the above technical solution, the following technical effects can be achieved: The positioning pin is locked and fixed by the fixing screw in cooperation with the fixing hole and the fixing threaded hole, aiming to limit and fix the upper seat, the boss, the pillar upper limit plate, and the pillar main body, and to prevent the upper seat, the boss, the pillar upper limit plate, and the pillar main body from shifting when detecting the pillar main body, thereby avoiding the influence on the detection efficiency of the pillar main body.

[0020] As a further solution of the present invention, two protrusions are symmetrically and fixedly connected to the inner wall of the limiting hole;

[0021] The distance between the two protrusions is the same as the inner diameter of the connecting hole.

[0026] Through the above technical solutions, the following technical effects can be achieved: By providing a groove, the groove can avoid the interference between the upper seat and the bolts of the pillar.

[0027] As a further solution of the present invention, the specific steps of the usage method of the connection device are as follows:

[0028] Step 1: First, use the first fixing bolt to connect the upper seat to the bottom of the detection device, and then the user uses the second fixing bolt to connect the pillar body to the bottom of the upper limiting plate of the pillar;

[0029] Step 2: Secondly, by placing the upper limiting plate of the pillar on the bottom of the upper seat, at this time, the connection hole on the surface of the upper limiting plate of the pillar and the limiting hole of the boss on the outer wall of the upper seat are on the same straight line. At this time, the user then clamps the positioning pin into the limiting hole and the connection hole, and the alignment work of the upper seat, the boss, and the upper limiting plate of the pillar can be quickly completed. At the same time, use the fixing screw to cooperate with the fixing hole and the fixing threaded hole to lock and fix the positioning pin, aiming to limit and fix the upper seat, the boss, the upper limiting plate of the pillar, and the pillar body. After the fixing screw locks the positioning pin, it indicates that the connection and fixation of the pillar body, the upper seat, and the upper limiting plate of the pillar are completed. The user then starts the detection device to detect the pillar body;

[0030] Step 3: Finally, when disassembling the whole, remove the second fixing bolt. At this time, the upper limit plate on the pillar is separated from the pillar main body; then remove the fixing screw from the fixing hole and the fixing threaded hole. At this time, the user can take out the positioning pin from the limit hole and the connection hole. At this time, the upper limit plate on the pillar is separated from the upper seat; then remove the first fixing bolt. At this time, the upper seat and the detection device are separated.

At this time, the connection hole 108 on the surface of the upper limit plate 107 of the pillar and the limit hole 105 of the boss 104 on the outer wall of the upper seat 101 are on the same straight line. Then the user snaps the positioning pin 106 into the limit hole 105 and the connection hole 108. At this time, the user uses the fixing screw 110 in cooperation with the fixing hole 109 and the fixing threaded hole 111 to lock and fix the positioning pin 106. After the fixing screw 110 locks the positioning pin 106, the user then uses the second fixing bolt 113 to connect the pillar main body 114 to the bottom of the upper limit plate 107 of the pillar;

[0048] Secondly, the user then starts the detection device to detect the pillar main body 114;

[0049] Finally, when the detection work of the pillar main body 114 is completed, the user needs to disassemble the whole at this time. First, the user can disassemble the second fixing bolt 113, and at this time, the upper limit plate 107 of the pillar is separated from the pillar main body 114;
