Description

Technical Field

[0001] This invention belongs to the field of front strut technology, specifically relating to a front strut assembly and a vehicle. Background Technology

[0002] In a car's suspension system, the front strut plays a crucial role. The shock absorbers in the front strut absorb impacts from the road surface and reduce vibrations, accelerating the attenuation of vibrations between the chassis and body to improve ride comfort. It significantly influences the dynamic performance of the car's suspension, thereby affecting the vehicle's handling stability and ride comfort.

[0003] The connection structure between the front strut shock absorber and the vehicle body is also crucial. In most models, the upper end of the shock absorber is directly connected to the vehicle's tower, while the lower oil reservoir is connected to a connecting bracket, the bottom of which is then connected to the vehicle's control arm. For example, a front shock absorber for automobiles is disclosed in Chinese Patent (Application No. 201920751722.9). Figure 1-3 As shown, the upper end of the lower bracket has an opening. When connecting the shock absorber and the lower bracket, insert the lower end of the shock absorber into the opening of the lower bracket, and then tighten the opening with bolts.

[0004] While the aforementioned patent facilitates the installation of the front strut shock absorber onto the vehicle body, when encountering shock absorbers with different lower diameters, the opening of the lower bracket needs to be designed with different dimensions to accommodate the installation of the shock absorber, which is not conducive to the platform design and cost optimization of the product. Summary of the Invention

[0005] The purpose of this invention is to provide a front strut assembly and vehicle to solve the problem mentioned in the background art, where when the diameter of the lower end of the shock absorber is different, the opening of the lower bracket needs to be designed with different sizes to accommodate the installation of the shock absorber, which is not conducive to the platform design and cost optimization of the product.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0007] In a first aspect, a front strut assembly is provided, including a shock absorber body and a connecting bracket, one end of the shock absorber body being fixed to the shock absorber tower of a vehicle, one end of the connecting bracket being hinged to the control arm of a vehicle, a connecting support being fixed to the end of the shock absorber body away from the shock absorber tower, and a connecting block being fixed to the end of the connecting bracket away from the control arm, the connecting block being detachably mounted on the connecting support.

[0008] In conjunction with the first aspect, it is further specified that when the connecting block and the connecting support are not relatively fixed, the connecting bracket can rotate around the hinge center between the connecting bracket and the control arm.

[0009] In conjunction with the first aspect, further defining the connection support as having a U-shaped structure, having an installation space within the connection support that accommodates the connection block, allowing the connection block to enter the installation space and be fixed to the connection support, and allowing the connection block to exit the installation space and separate from the connection support.

[0010] In conjunction with the first aspect, further defining the connection support, the connection support includes a main connection plate and side connection plates fixed on both sides of the main connection plate. The main connection plate and the side connection plates on both sides together form the installation space. The side of the main connection plate facing away from the installation space is welded to the shock absorber body.

[0011] In conjunction with the first aspect, it is further specified that the connecting block is detachably installed on the connecting support by means of bolt connection.

[0012] In conjunction with the first aspect, further defining the first bolt connection hole on the connecting block and the second bolt connection hole adapted to the first bolt connection hole on the connecting support, when the first bolt connection hole and the adapted second bolt connection hole are coaxial, the first bolt connection hole and the second bolt connection hole can be used together to pass through the fixing bolt, and the end of the fixing bolt away from the nut is threaded with a nut.

[0013] In conjunction with the first aspect, further defining the shock absorber body, an upper mounting base is fixed at one end away from the connecting support, and the upper mounting base is installed on the shock absorber tower by means of bolt connection; an upper spring pad is fixed on the upper mounting base, a lower connecting base is installed in the middle of the shock absorber body, and a helical spring and a dust cover are installed between the upper spring pad and the lower connecting base on the shock absorber body.

[0014] In conjunction with the first aspect, further defining the first aspect, the connecting bracket has two connecting legs, and the connecting legs are provided with hinge holes adapted to the hinge points of the control arm.

[0015] In a second aspect, a vehicle is provided, the vehicle comprising a vehicle body, a shock absorber tower, a control arm, a steering knuckle assembly, and a front strut assembly of the first aspect, wherein the shock absorber tower, the control arm, the steering knuckle assembly, and the front strut assembly are all mounted on the vehicle body, one end of the control arm is mounted on the steering knuckle assembly, and both ends of the front strut assembly are respectively mounted on the shock absorber tower and the control arm.

[0016] The invention employing the above technical solution has the following advantages:

[0017] 1. Through the cooperation of the connecting bracket and the connecting block, it is not only easy to fix the shock absorber body and the connecting bracket together, but also the connecting bracket can be fixed on the shock absorber body of any diameter, so it can be used with shock absorbers of any diameter, which is very beneficial to the platform design and cost optimization of the product.

[0018] 2. By cooperating with the connecting bracket and the connecting block, when it is necessary to disassemble the shock absorber body and / or the connecting bracket, simply make the connecting block and the connecting bracket not fixed relative to each other, and then rotate the connecting bracket to separate the shock absorber body and the connecting bracket. The shock absorber body and / or the connecting bracket can be disassembled without disassembling the control arm and the steering knuckle assembly, which is quite convenient.

[0031] The present application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. In the description of this application, terms such as "first" and "second" are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figure 8 As shown, this application embodiment provides a front strut assembly, mainly including a shock absorber body 100 and a connecting bracket 200. The upper end of the shock absorber body 100 can be fixed to the vehicle's shock absorber tower 300, and the lower end of the connecting bracket 200 is hinged to the vehicle's control arm 400. The lower end of the shock absorber body 100 is connected to the upper end of the connecting bracket 200, thereby forming the vehicle's force transmission structure, thereby absorbing the impact from the road surface on the front suspension of the car and reducing vibration, and accelerating the attenuation of the vibration of the frame and body.

[0033] like Figures 5-7 As shown, in this embodiment, a connecting support 110 is fixed to the end of the shock absorber body 100 away from the shock absorber tower 300, and a connecting block 210 is fixed to the end of the connecting bracket 200 away from the control arm 400. The connecting block 210 is detachably mounted on the connecting support 110. Through the cooperation of the connecting support 110 and the connecting block 210, it is not only convenient to fix the shock absorber body 100 and the connecting bracket 200 together, but also the connecting support 110 can be fixed on the shock absorber body 100 of any diameter, thus making it suitable for shock absorbers of any diameter. This is very beneficial for the platform design and cost optimization of the product.

[0034] Figure 4 This is a partial schematic diagram of the shock absorber body 100 and connecting bracket 200 installed on a vehicle in the prior art, as shown below. Figure 4As shown, when it is necessary to disassemble the shock absorber body 100 and / or the connecting bracket 200, the bolts that pre-tighten the opening of the connecting bracket 200 are first removed. However, since the lower end of the shock absorber body 100 is installed in the opening of the connecting bracket 200, and the lower end of the shock absorber body 100 is always pressed against the connecting bracket 200 under its own elastic force, the Z-direction space of the connecting bracket 200 is insufficient. Therefore, to separate the shock absorber body 100 and / or the connecting bracket 200, other tools must be used to move the lower end of the shock absorber body 100 out of the opening of the connecting bracket 200, or the vehicle's control arm 400 must be removed. In some models, it is even necessary to simultaneously remove the control arm 400 and the steering knuckle assembly 500 to separate the shock absorber body 100 and the connecting bracket 200, making the disassembly process very troublesome.

[0035] like Figure 9 As shown, in this embodiment, when the connecting block 210 and the connecting support 110 are relatively fixed, the shock absorber body 100 and the connecting bracket 200 can serve as the force transmission structure of the vehicle; while when the connecting block 210 and the connecting support 110 are not relatively fixed, the connecting bracket 200 can rotate around the hinge center between the connecting bracket 200 and the control arm 400. With this design, when it is necessary to disassemble the shock absorber body 100 and / or the connecting bracket 200, it is only necessary to make the connecting block 210 and the connecting support 110 not relatively fixed, and then rotate the connecting bracket 200 to separate the shock absorber body 100 and the connecting bracket 200. The shock absorber body 100 and / or the connecting bracket 200 can be removed without disassembling the control arm 400 and the steering knuckle assembly 500, which is quite convenient.

[0036] like Figures 5-7 As shown, in this embodiment, the connecting support 110 is designed as a U-shaped structure, and the connecting block 210 is a block structure. The connecting support 110 has an installation space 111 that accommodates the connecting block 210. The connecting block 210 can enter the installation space 111 and then be fixed to the connecting support 110, thereby fixing the shock absorber body 100 and the connecting bracket 200 relatively. The connecting block 210 can also exit the installation space 111, separating the connecting block 210 from the connecting support 110, thereby preventing the shock absorber body 100 and the connecting bracket 200 from being relatively fixed.

[0037] like Figure 5As shown, in this embodiment, the connecting support 110 includes a main connecting plate 112 and side connecting plates 113 integrally formed on both sides of the main connecting plate 112. The main connecting plate 112 and the side connecting plates 113 on both sides together form a U-shaped structure of the connecting support 110, and the main connecting plate 112 and the side connecting plates 113 on both sides together form an installation space 111. The side of the main connecting plate 112 facing away from the installation space 111 is welded to the lower end of the shock absorber body 100, thereby fixing the connecting support 110 to the shock absorber body 100.

[0038] like Figures 5-7 As shown, in this embodiment, the connecting block 210 is detachably installed on the connecting support 110 mainly by means of bolt connection, which facilitates the installation or disassembly of the connecting block 210 and the connecting support 110.

[0039] like Figures 5-7 As shown, specifically, the connecting block 210 has two first bolt connection holes 211, and the connecting support 110 has a second bolt connection hole 114 that matches the first bolt connection holes 211. When installing the connecting support 110 and the connecting block 210, firstly, the first bolt connection holes 211 and their matching second bolt connection holes 114 are aligned coaxially. The first bolt holes 211 and the second bolt holes 114 can both accommodate a fixing bolt. The end of the fixing bolt away from the nut is then threaded with a nut, thus fixing the connecting block 210 and the connecting support 110 together. When disassembly is required, the fixing bolt and nut can be directly removed, which is very convenient.

[0040] like Figure 5 As shown, in this embodiment, an upper mounting base 120 is fixed to one end of the shock absorber body 100 away from the connecting support 110. The upper mounting base 120 is installed on the shock absorber tower 300 by bolt connection, thereby installing the shock absorber body 100 on the shock absorber tower 300. An upper spring pad 130 is fixed on the upper mounting base 120. A lower connecting base 140 is installed in the middle of the shock absorber body 100. A coil spring 150 and a dust cover 160 are installed between the upper spring pad 130 and the lower connecting base 140 on the shock absorber body 100.

[0041] like Figure 6 As shown, in this embodiment, the connecting bracket 200 has two connecting legs 220, and the connecting legs 220 are provided with hinge holes 221 adapted to the hinge points of the control arm 400. When installing the connecting bracket 200, the connecting bracket 200 is installed onto the control arm 400 mainly by passing bushings and bolts through the hinge holes 221 of the connecting bracket 200 and the hinge points of the control arm 400. When the bolts are loosened, the connecting bracket 200 can rotate relatively easily around the hinge center. When the bolts are tightened, the connecting bracket 200 is not easy to rotate around the hinge center.

[0042] like Figure 8 and Figure 9 As shown in the illustration, this application also provides a vehicle, which includes a vehicle body, a shock absorber tower 300, a control arm 400, a steering knuckle assembly 500, and a front strut assembly as described above. The shock absorber tower 300, control arm 400, steering knuckle assembly 500, and front strut assembly are all mounted on the vehicle body. One end of the control arm 400 is mounted on the steering knuckle assembly 500, and both ends of the front strut assembly are mounted on the shock absorber tower 300 and the control arm 400, respectively. With this configuration, when it is necessary to disassemble the shock absorber body 100 and / or the connecting bracket 200 in the steering knuckle assembly 500, it is only necessary to make the connecting block 210 and the connecting support 110 not relatively fixed, and then rotate the connecting bracket 200 to separate the shock absorber body 100 and the connecting bracket 200. The shock absorber body 100 and / or the connecting bracket 200 can be removed without disassembling the control arm 400 and the steering knuckle assembly 500, which is quite convenient.
