Abstract
Description
Technical Field
[0001] This utility model relates to the field of independent suspension support technology, and specifically to an independent suspension support structure. Background Technology
[0002] In the field of commercial vehicle engineering, traditional independent suspension models generally adopt a shock absorber support structure with bolts fixed on one side. This support is anchored to the belly surface of the frame (i.e., the side wall plane of the frame) on one side by a group of high-strength bolts, forming a cantilever connection. From a mechanical point of view, this connection method has significant defects under vehicle driving conditions: when the vehicle encounters lateral (Y-direction) loads such as road lateral protrusions and centrifugal forces in curves, the shock absorber support, as the force transmission hub, bears dynamic alternating stress. However, since the support is a single-point connection, it cannot form an effective constraint surface, and the lateral (Y-direction) load is difficult to distribute evenly, resulting in significant stress concentration in the support. Long-term stress concentration will cause deformation of the support, seriously threatening driving safety and transportation efficiency. We propose an independent suspension support structure to solve the above problems. Utility Model Content
[0003] The present invention aims to provide an independent suspension support structure to solve the problem that the lateral load of the existing support is difficult to distribute, resulting in the deformation of the support.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: an independent suspension support structure, comprising a support part, a fixing part, and an extension part connected in sequence. The fixing part is fixedly installed on the outer wall of the vehicle frame by bolts. The support part is located at the upper end of the fixing part. The end of the support part away from the fixing part is provided with a connecting surface for installing a shock absorber. The extension part is located at the lower end of the fixing part and abuts against the lower end of the vehicle frame. The extension part is parallel to the connecting surface.
[0005] The beneficial effects of this solution are as follows: By fixing the fixed part and the extension part to the outer wall of the frame respectively, the shock absorber support is supported along the direction of the extension part (i.e., the Y direction), which reduces the Y-direction deformation of the shock absorber support from 6mm to 4mm, a reduction of 40%-50%, greatly enhancing the lateral support stability of the suspension; at the same time, the setting of the extension part can make the stress distribution on the bracket more uniform, increasing the fatigue life of the frame connection area by more than 3 times; moreover, this support is compatible with the existing frame structure, without the need to modify the production line, significantly reducing production modification costs and time costs while ensuring high performance.
[0006] Preferably, as an improvement, the support portion has a through groove.
[0007] The beneficial effects are: opening through slots in the support section can effectively reduce the overall weight of the support, achieving structural lightweighting without affecting the key load-bearing capacity.
[0008] Preferably, as an improvement, the sidewall of the support part is provided with side plates symmetrically, and the side plates are connected to the sidewall of the connecting surface.
[0009] The beneficial effects are: the symmetrically distributed side plates, support parts, and connecting surfaces form a closed mechanical frame, which can evenly distribute the force to the entire structure when the shock absorber transmits the load.
[0010] Preferably, as an improvement, the connection between the side plate and the support is rounded.
[0011] Preferably, as an improvement, the fixing part is configured as an L-shape, and the two sides of the fixing part are symmetrically provided with reinforcing plates.
[0012] Preferably, as an improvement, the connection between the fixing part and the supporting part is rounded. Attached Figure Description

[0017] Example
[0018] The basic implementation examples are as follows: Figures 1-1 As shown, Figure 1 The diagram shows an independent suspension support structure, with supports 1 symmetrically arranged on the left and right sides of the vehicle frame 2, as shown. Figure 2The support 1 shown includes a support part 3, a fixing part 4, and an extension part 5 connected sequentially from top to bottom. The support 1 is integrally formed by stamping technology. The fixing part 4 is fixedly installed on the outer wall of the frame 2 by bolts. The fixing part 4 is L-shaped. Reinforcing plates 9 are symmetrically fixed on the left and right sides of the fixing part 4. The support part 3 is located at the upper front end of the fixing part 4. The connection between the fixing part 4 and the support part 3 is rounded. A through groove 7 is provided in the middle of the support part 3. The through groove 7 is rectangular. A connecting surface 6 is provided at the upper end of the support part 3. The connecting surface 6 is used to install shock absorbers. Side plates 8 are symmetrically provided on the left and right side walls of the support part 3. The upper end of the side plate 8 is connected to the side wall of the connecting surface 6. The connection between the side plate 8 and the support part 3 is rounded. The extension part 5 is located at the lower end of the fixing part 4 and abuts against the lower end of the frame 2. The extension part 5 is fixedly connected to the lower wall of the frame 2 by bolts. The extension part 5 is parallel to the connecting surface 6.
[0019] The specific implementation process is as follows:
[0020] By fixing the fixing part 4 and the extension part 5 to the outer wall of the frame 2 respectively, the shock absorber support 1 is supported along the direction of the extension part 5 (i.e., the Y direction), which reduces the Y-direction deformation of the shock absorber support 1 from 6mm to 4mm, a reduction of 40%-50%, greatly enhancing the lateral support stability of the suspension. At the same time, the setting of the extension part 5 can make the stress distribution on the bracket more uniform, increasing the fatigue life of the connection area of the frame 2 by more than 3 times. Moreover, the support 1 is compatible with the existing frame 2 structure, without the need to modify the production line, which significantly reduces the production modification cost and time cost while ensuring high performance.
