[0001] The present application relates to the technical field of suspension assemblies, and in particular to a linkage structure of a suspension assembly and a suspension assembly. Background Art

[0002] At present, the suspension of semi-trailers all adopts leaf spring balanced suspension. In actual driving, due to the influence of road unevenness and the alternating loads generated during vehicle starting and braking conditions, the suspension bracket of the semi-trailer will be affected by the alternating loads. Under the repeated action of such alternating loads, cracks will occur and expand. In the absence of adjustment buffering and monitoring and early warning, the suspension bracket of the semi-trailer will suddenly break, leaving a safety hazard.

[0003] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present invention, and therefore may contain information that does not constitute prior art.

[0006] To achieve the above objectives, this application is implemented through the following technical solutions:

[0007] The linkage structure of the suspension assembly includes a front bracket assembly, an intermediate bracket assembly and a rear bracket assembly.

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0026] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of this application.

[0027] Example 1

[0028] like Figures 1 to 4 As shown, the linkage structure of the suspension assembly described in this application includes a front support assembly 1, an intermediate support assembly 2, and a rear support assembly 3. A leaf spring structure is provided between the front support assembly 1 and the intermediate support assembly 2, and another leaf spring structure is provided between the intermediate support assembly 2 and the rear support assembly 3. This is the leaf spring balanced suspension currently used in semi-trailer suspensions. This suspension can absorb the effects of road roughness and the alternating loads generated during vehicle starting and braking conditions during actual operation.

[0029] The leaf spring structure includes a leaf spring member 4 and a leaf spring adjustment buffer member 5 for adjusting the posture of the leaf spring member 4. The leaf spring adjustment buffer member 5 is provided at the end of the leaf spring member 4. It is easy to understand that the two leaf spring adjustment buffer members 5 provided at both ends of the leaf spring member 4 can respectively adjust the installation position of the two ends of the leaf spring member 4.

[0030] Taking the leaf spring structure installed between the front bracket assembly 1 and the intermediate bracket assembly 2 as an example, the height of the leaf spring component 4 at one end of the front bracket assembly 1 and the height of the leaf spring component 4 at one end of the intermediate bracket assembly 2 can be adjusted separately, so that the height of the leaf spring component 4 at one end of the front bracket assembly 1 can be higher than the height of the leaf spring component 4 at one end of the intermediate bracket assembly 2, or the height of the leaf spring component 4 at one end of the front bracket assembly 1 can be lower than the height of the leaf spring component 4 at one end of the intermediate bracket assembly 2, or the height of the leaf spring component 4 at one end of the front bracket assembly 1 can be equal to the height of the leaf spring component 4 at one end of the intermediate bracket assembly 2.

[0031] Specifically, the leaf spring adjustment buffer 5 includes a fixed plate 51 and a sliding plate 52. The sliding plate 52 is fixedly connected to the end of the leaf spring member 4 and is slidably connected to the fixed plate 51. The leaf spring adjustment buffer 5 also includes a locking bolt 53 for locking the sliding plate 52 to the fixed plate 51. One end of the locking bolt 53 is connected to a bolt hole formed in the fixed plate 51, and the other end of the locking bolt 53 is fixedly connected to a corresponding one of the multiple bolt holes formed in the sliding plate 52.

[0032] It is easy to understand that after the sliding plate 52 slides relative to the fixed plate 51 to adjust the position of the end of the leaf spring 4, it is necessary to tighten the locking bolt 53 to keep the sliding plate 52 fixed relative to the fixed plate 51. Similarly, after unscrewing the locking bolt 53, the sliding plate 52 can slide again relative to the fixed plate 51.

[0033] The leaf spring structure includes a leaf spring monitoring and warning member 6 for detecting breakage before the semi-trailer's suspension bracket breaks. The leaf spring monitoring and warning member 6 is connected to the intermediate bracket assembly 2. As will be readily understood, by regularly monitoring the leaf spring monitoring and warning member 6 for breakage, the quality and service life of the semi-trailer's suspension bracket can be clearly determined.

[0034] Specifically, the leaf spring monitoring and warning component 6 includes a monitoring and warning elastic member 61, one end of which is fixedly connected to the intermediate bracket assembly 2, and the other end of which is fixedly connected. The leaf spring monitoring and warning component 6 also includes a hanging plate 62 and an adjustable plate 63. The hanging plate 62 is fixedly connected to the leaf spring component 4, the adjustable plate 63 is fixedly connected to the hanging plate 62, and the monitoring and warning elastic member 61 is fixedly connected to the adjustable plate 63.

[0035] As will be readily understood, the monitoring and warning elastic member 61 can be a coil spring of lower quality and service life than the semi-trailer's suspension bracket. By removing the adjustable plate 63 and installing it in the appropriate position on the hanging plate 62, the coil spring is restored to its original length or slightly extended. In short, the coil spring extends synchronously with the downward deformation of the leaf spring member 4. Over long-term use, the coil spring, due to its lower quality and service life than the semi-trailer's suspension bracket, may break prematurely.

[0036] The linkage structure of the suspension assembly described in the present application also includes a leaf spring auxiliary support member for assisting in adjusting the posture of the leaf spring member 4. It is easy to understand that the leaf spring auxiliary support member and the leaf spring adjustment buffer member 5 can be used in conjunction with each other to help better adjust the posture of the leaf spring member 4.

[0037] Taking the leaf spring structure installed between the front bracket assembly 1 and the intermediate bracket assembly 2 as an example, if the height of the leaf spring component 4 at one end of the front bracket assembly 1 needs to be raised, the leaf spring auxiliary support member can be retracted to help the leaf spring component 4 rise at that end of the front bracket assembly 1. In this way, the weight of the leaf spring component 4 is fully supported by the leaf spring auxiliary support member.

[0038] Specifically, the leaf spring auxiliary support member includes an adjustable telescopic cylinder 71 , one end of the adjustable telescopic cylinder 71 is rotatably connected to the leaf spring adjustment buffer member 5 , and the other end of the adjustable telescopic cylinder 71 is rotatably connected to the leaf spring monitoring and early warning member 6 .
