Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of vehicle assembly, and in particular to an assembly tool for a front strut assembly. Background Art

[0002] The suspension system of a vehicle, also known as the suspension system, is a support structure that connects the vehicle body and the wheels in the vehicle. Its function is to transmit the forces and torques acting between the wheels and the vehicle body, buffer the impact force transmitted from the uneven road surface to the frame or the vehicle body, and at the same time attenuate the vibration caused thereby, so as to ensure that the vehicle can drive smoothly. In the suspension system, the function of the front strut assembly is to elastically connect the steering knuckle and the vehicle body and play a role in alleviating the road surface impact. During the vehicle assembly process, generally, the front strut assembly is first assembled with the steering knuckle, and then assembled with the shock tower on the vehicle body.

[0003] In the solutions of the related art, when the front strut assembly is connected to the shock tower, it is necessary to assemble the bolts at the end of the front strut assembly with the corresponding threaded holes on the shock tower. During the assembly, the operator is located on the side of the shock tower away from the front strut assembly, and the front strut assembly moves towards the shock tower for assembly. Since the operator's line of sight is blocked by the shock tower, the assembly situation cannot be directly observed; if the front strut assembly swings during the assembly process, it may cause the problem that the bolts cannot be aligned with the threaded holes, resulting in difficult assembly. Summary of the Utility Model

[0004] In view of this, the embodiments of the present application provide an assembly tool for a front strut assembly to reduce the assembly difficulty between the front strut assembly and the shock tower.

[0005] In order to achieve the above object, the technical solution of the embodiments of the present application is realized as follows:

[0006] The embodiments of the present application provide an assembly tool for a front strut assembly, including: a tooling body, the tooling body is used for detachably installing at the end of the front strut assembly, and the tooling body is also used for passing through the through hole of the shock tower.

[0007] During the assembly of the embodiments of the present application, the tooling body can be detachably connected to the end of the front strut assembly, and then the tooling body is passed through the through hole of the shock tower. The operator is located on the side of the shock tower away from the front strut assembly, and the tooling body exposed outside the shock tower is pulled to guide the front strut assembly close to the shock tower, so as to ensure that the bolts at the end of the front strut assembly are aligned with the corresponding threaded holes on the shock tower, thereby reducing the assembly difficulty between the front strut assembly and the shock tower.

[0008] In a possible implementation of the present application, in a plane perpendicular to the assembly direction of the front pillar assembly, along the assembly direction of the front pillar assembly, the cross-sectional area of ​​the tooling body gradually decreases, and the cross-sectional area of ​​the through hole gradually decreases.

[0009] Along the assembly direction of the front pillar assembly, the embodiment of the present application sets the cross-sectional area of ​​the tooling body to be gradually reduced, so as to adapt to the through hole with a gradually reduced cross-sectional area. During assembly, the end of the tooling body with a smaller cross-sectional area first contacts the end of the through hole with a larger cross-sectional area to ensure that the tooling body can smoothly enter the through hole; as the assembly proceeds, the cross-sectional area of ​​the tooling body at a certain fixed position in the through hole gradually increases, so that the tooling body fits the inner wall of the through hole, thereby achieving a guiding effect on the tooling body, ensuring that the tooling body can move along the through hole, so as to guide the bolts at the end of the front pillar assembly to gradually approach the corresponding threaded holes on the vibration damping tower.

[0010] In a possible implementation of the present application, in a plane perpendicular to the assembly direction of the front pillar assembly, the maximum diameter of the tooling body is smaller than the minimum inner diameter of the through hole, and the difference between the minimum inner diameter of the through hole and the maximum diameter of the tooling body is 2-3 mm.

[0011] The embodiment of the present application limits the difference between the maximum diameter of the front pillar assembly and the minimum diameter of the through hole to within a range of 2-3 mm to ensure that the tooling body has a smaller swing range after entering the through hole. When the tooling body swings in the through hole, one side of the tooling body sticks to the inner wall of the through hole, and then uses the inner wall of the through hole as a guide to gradually move along the inner wall of the through hole to guide the bolts at the end of the front pillar assembly to gradually approach the corresponding threaded holes on the shock absorbing tower.

[0012] In a possible implementation of the present application, the tooling body includes a first surface and a side surface connected to the first surface, the first surface is used for detachable connection with the front pillar assembly, and an end of the side surface facing away from the first surface is also provided with an arc-shaped transition surface.

[0013] During assembly of the embodiment of the present application, the arcuate transition surface first enters the through hole, and the arcuate transition surface is used to achieve a guiding function during assembly, thereby ensuring that the tooling body smoothly enters the through hole.

[0014] In a possible implementation of the present application, a gripping portion is further provided on the arc-shaped transition surface.

[0015] The embodiment of the present application provides a gripping portion to facilitate an operator to pull the tool body to adjust the position of the tool body in the through hole, thereby ensuring that the bolts at the ends of the front strut assembly are aligned with the corresponding threaded holes on the shock absorbing tower.

[0016] In a possible implementation manner of the present application, the holding portion includes a connecting section and a holding section. In a plane perpendicular to the assembly direction of the front strut assembly, the size of the connecting section is smaller than that of the holding section.

[0017] In the embodiment of the present application, by setting the size of the holding section to be larger than that of the connecting section, it is convenient for the operator to grasp the holding section to adjust the position of the tooling body in the through hole.

[0018] In a possible implementation manner of the present application, an assembly hole is provided on the first surface, and the assembly hole is used for detachably connecting with the piston rod of the front strut assembly.

[0019] In the embodiment of the present application, by providing that the assembly hole is detachably connected with the piston rod on the front strut assembly, there is no need to provide a corresponding detachable connection structure on the front strut assembly, making full use of the existing structure on the front strut assembly, which is beneficial to reducing the number of parts.

[0020] In a possible implementation manner of the present application, a magnetic member is provided in the assembly hole, and the magnetic member is used for detachably connecting with the piston rod.

[0021] In the embodiment of the present application, the detachable connection between the assembly hole and the piston rod is realized by magnetic attraction, thus ensuring a relatively fast installation and disassembly speed of the tooling body and the front strut assembly.

[0022] In a possible implementation manner of the present application, a threaded section is provided in the assembly hole, and the threaded section is used for threaded connection with the piston rod.

[0023] In the embodiment of the present application, by providing a threaded section in the assembly hole, the threaded section is used to connect with the existing thread on the piston rod, making full use of the existing structure on the front strut assembly, which is beneficial to reducing the number of parts.

[0024] In a possible implementation manner of the present application, an avoidance groove is further provided on the first surface. The assembly hole is located in the avoidance groove, and the avoidance groove is used for adapting to the protrusion on the front strut assembly.

[0025] In the embodiment of the present application, by providing the avoidance groove, the tooling body can be attached to the end of the front strut assembly, so that the stress can be dispersed, reducing the situation of single-point force on the tooling body, which is beneficial to improving the strength of the overall structure.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will further describe the specific technical solutions of the present application in detail with reference to the accompanying drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present application, unless otherwise specified, the meaning of "plurality" is two or more.

[0036] In addition, in the embodiments of the present application, orientation terms such as "upper", "lower", "left", and "right" are defined relative to the orientation in which the components in the drawings are schematically placed. It should be understood that these directional terms are relative concepts, and they are used for relative description and clarification, and they may change accordingly with the change of the orientation in which the components in the drawings are placed.

[0037] In the embodiments of the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be fixedly connected, detachably connected, or integrated; it can be directly connected or indirectly connected through an intermediate medium.

[0038] In the embodiments of the present application, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising a..." does not exclude the existence of additional identical elements in the process, method, article or device comprising such element.

[0039] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations.

Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0040] As described in the background art, there is a problem of difficult assembly when the front strut assembly is assembled with the shock tower on the vehicle body. The reason for the above problem is that: after the front strut assembly is first assembled and fixed with the steering knuckle and then moved together towards the shock tower for assembly, there is still a certain assembly distance between the front strut assembly and the shock tower at this time. During the movement of the front strut assembly towards the shock tower, the swing amount in the plane is relatively large, making it difficult for the bolts at the end of the front strut assembly to align with the corresponding threaded holes on the shock tower. Since the operator is located on the side of the shock tower away from the front strut assembly during assembly, the operator's line of sight is blocked by the shock tower, so the assembly situation cannot be directly observed; it is difficult to straighten the bolts at the end of the front strut assembly after they are offset, resulting in difficult assembly.

[0041] In view of this, the embodiments of the present application aim to provide an assembly tooling for the front strut assembly. By providing a tooling body for detachably connecting to the end of the front strut assembly, the tooling body is also used to pass through the through hole of the shock tower. During assembly, the tooling body can be detachably connected to the end of the front strut assembly, and then the tooling body is passed through the through hole of the shock tower. The operator is located on the side of the shock tower away from the front strut assembly, and by pulling the tooling body exposed outside the shock tower to guide the front strut assembly close to the shock tower, it is ensured that the bolts at the end of the front strut assembly are aligned with the corresponding threaded holes on the shock tower, so as to reduce the assembly difficulty between the front strut assembly and the shock tower.

[0042] Next, the embodiments of the present application will be described in detail with reference to the drawings. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation of the present application.

[0043] The embodiment of the present application provides an assembly tool for a front strut assembly, which is used to assist in the assembly of a vehicle. It should be noted that the vehicle in the present application may refer to large vehicles, small vehicles, special vehicles, etc. Exemplarily, classified by vehicle type, the vehicle in the present application may be a sedan model, an off-road model, a multi-purpose vehicle (MPV) model or other models. For a vehicle, generally, wheels, a body, and a suspension system provided between the wheels and the body are provided. The suspension system can transmit the forces and torques acting between the wheels and the body, buffer the impact force transmitted from the uneven road surface to the frame or the body, and at the same time attenuate the vibration caused thereby to ensure that the vehicle can drive smoothly.

[0044] It should be noted that in the embodiment of the present application, the type of the suspension system of the vehicle is not limited. Exemplarily, the suspension system may be a non-independent suspension system or an independent suspension system. The suspension system includes components such as a front strut assembly, a shock tower, and a guiding mechanism. The assembly tool for the front strut assembly in the embodiment of the present application can be used to assist in the assembly of the front strut assembly and the shock tower on the vehicle body.

[0045] Please refer to Figures 1-4 , the assembly tool for the front strut assembly provided by the embodiment of the present application includes: a tool body 100. The tool body 100 is used for detachably installing at the end of the front strut assembly 200, and the tool body 100 is also used for passing through the through hole 310 of the shock tower 300.

[0046] Exemplarily, as Figures 2-4 shown, for some vehicles, a plurality of bolts 210 are provided at the end of the front strut assembly 200, a through hole 310 and a plurality of bolt holes 320 are provided on the shock tower 300, and the plurality of bolt holes 320 are arranged around the through hole 310. The plurality of bolts 210 correspond to the plurality of bolt holes 320 one by one. When the front strut assembly 200 is connected to the shock tower 300, the front strut assembly 200 moves along the Figure 4 X direction shown by the arrow in Figure 4 to respectively assemble and connect the plurality of bolts 210 with the plurality of bolt holes 320 one by one. Since there is a certain assembly distance between the bolt 210 and the bolt hole 320, and the front strut assembly 200 will swing in the

[0047] Please continue to refer to Figure 1 and Figure 4The tooling body 100 of this embodiment can be generally truncated cone or prism-shaped, preferably generally truncated cone-shaped to roughly match the shape of the through hole 310. During assembly of the embodiment of the present application, the tooling body 100 can be detachably connected to the end of the front pillar assembly 200, and then the tooling body 100 is inserted into the through hole 310 of the vibration-damping tower 300. The operator is located on the side of the vibration-damping tower 300 away from the front pillar assembly 200, and guides the front pillar assembly 200 to approach the vibration-damping tower 300 by pulling the tooling body 100 exposed outside the vibration-damping tower 300, thereby ensuring that the bolts 210 at the end of the front pillar assembly 200 are aligned with the corresponding threaded holes 320 on the vibration-damping tower 300, so as to reduce the difficulty of assembling the front pillar assembly 200 and the vibration-damping tower 300.

[0048] like Figure 4 As shown, in some embodiments, in a plane perpendicular to the assembly direction of the front pillar assembly 200 (ie Figure 4 AA plane), along the assembly direction of the front pillar assembly 200 (i.e. Figure 4 In the X direction as indicated by the arrow in the middle), the cross-sectional area of ​​the tool body 100 gradually decreases, and the cross-sectional area of ​​the through hole 310 gradually decreases. That is to say, the cross-sectional area of ​​the tool body 100 and the cross-sectional area of ​​the through hole 310 of this embodiment are gradually changed, so that the tool body 100 and the through hole 310 are adapted to each other. Since the position of the vibration damping tower 300 is fixed, during assembly, along the assembly direction of the front pillar assembly 200, the end with a smaller cross-sectional area of ​​the tool body 100 is first matched with the end with a larger cross-sectional area of ​​the through hole 310 to ensure that the tool body 100 can smoothly enter the through hole 310. As the assembly proceeds, the cross-sectional area of ​​the tooling body 100 at a certain fixed position in the through hole 310 gradually increases, so that the tooling body 100 fits against the inner wall of the through hole 310, thereby achieving a guiding effect on the tooling body 100 and ensuring that the tooling body 100 can move along the through hole 310 to guide the bolt 210 at the end of the front pillar assembly 200 to gradually approach the corresponding threaded hole 320 on the vibration damping tower 300.

[0049] like Figure 1 , Figure 3 and Figure 4 As shown, further, in a plane perpendicular to the assembly direction of the front pillar assembly 200, the maximum diameter D1MAX of the tool body 100 is smaller than the minimum inner diameter D2MIN of the through hole 310, and the difference between the minimum inner diameter D2MIN of the through hole 310 and the maximum diameter D1MAX of the tool body 100 is 2-3 mm.

[0050] It can be understood that along the assembly direction of the front strut assembly 200, since the cross-sectional area of the tooling body 100 gradually decreases, one side of the tooling body 100 for connecting the front strut assembly 200 is at its maximum diameter; since the cross-sectional area of the through hole 310 also gradually decreases, the side of the through hole 310 facing away from the front strut assembly 200 is at its minimum diameter. In the embodiment of the present application, by limiting the range of the difference between the maximum diameter D1MAX of the front strut assembly 200 and the minimum diameter D2MIN of the through hole 310 to be within 2 - 3 mm, it is ensured that the tooling body 100 has a small swing range after entering the through hole 310. When the tooling body 100 swings in the through hole 310, one side of the tooling body 100 abuts against the inner wall of the through hole 310, and then using the inner wall of the through hole 310 as a guide, it gradually moves along the inner wall of the through hole 310 to guide the bolt 210 at the end of the front strut assembly 200 to gradually approach the corresponding threaded hole 320 on the shock absorber tower 300.

[0051] Please continue to refer to Figure 1 , in some embodiments, the tooling body 100 of the embodiment of the present application includes a first surface 110 and a side surface 120 connecting the first surface 110, and an arc transition surface 130 is further provided at one end of the side surface 120 facing away from the first surface 110. Among them, the first surface 110 is used for detachably connecting with the front strut assembly 200, and its specific detachable connection structure can be set according to actual needs. The side surface 120 is an inclined surface, so that the cross-sectional area of the tooling body 100 along the assembly direction of the front strut assembly 200 gradually decreases. Compared with the side surface 120, the cross-sectional area of the tooling body 100 along the assembly direction of the front strut assembly 200 further decreases at the arc transition surface 130, so that one end of the tooling body 100 that first enters the through hole 310 is much smaller than the inner diameter of the through hole 310, so as to play a guiding role during assembly.

[0052] It can be understood that during the assembly of the embodiment of the present application, the arc transition surface 130 first enters the through hole 310, and the arc transition surface 130 is used to realize the guiding role during assembly to ensure that the tooling body 100 smoothly enters the through hole 310.

[0053] In some embodiments, a holding portion 140 is further provided on the arc transition surface 130 of the embodiment of the present application. The structure of the holding portion 140 can be set according to needs, for example, it can be a pull ring, a handle and other structures provided on the arc transition surface 130.

[0054] By providing the holding portion 140 in the embodiment of the present application, it is convenient for the operator to pull the tooling body 100, so as to facilitate the operator to adjust the position of the tooling body 100 in the through hole 310, so as to straighten the bolt 210 at the end of the front strut assembly 200 after it is offset, and ensure that the bolt 210 at the end of the front strut assembly 200 is aligned with the corresponding threaded hole 320 on the shock absorber tower 300.

[0055] Exemplarily, as Figure 1 shown, the holding part 140 of this embodiment includes a connecting section 141 and a holding section 142. In a plane perpendicular to the assembly direction of the front strut assembly 200, the size of the connecting section 141 is smaller than that of the holding section 142. That is to say, the holding section 142 of this embodiment can be provided to protrude from the connecting section 141, so as to facilitate the operator to grasp the holding section 142, and then adjust the position of the tooling body 100 in the through hole 310, align the front strut assembly 200 connected to the tooling body 100, and ensure that the bolt 210 at the end of the front strut assembly 200 is aligned with the corresponding threaded hole 320 on the shock absorber tower 300.

[0056] Please continue to refer to Figure 1 and Figure 4 , in some embodiments, an assembly hole 150 is provided on the first surface 110 of the embodiment of the present application, and the assembly hole 150 is used for detachably connecting with the piston rod 220 of the front strut assembly 200.

[0057] It can be understood that by providing the assembly hole 150 to be detachably connected with the piston rod 220 on the front strut assembly 200 in the embodiment of the present application, there is no need to provide a corresponding detachable connection structure on the front strut assembly 200, making full use of the existing structure on the front strut assembly 200, which is beneficial to reducing the number of parts.

[0058] In some possible implementation manners, a magnetic member 160 is provided in the assembly hole 150 of the embodiment of the present application, and the magnetic member 160 is used for detachably connecting with the piston rod 220.

[0059] Exemplarily, the magnetic member 160 in the embodiment of the present application can be, for example, a magnet, and the piston rod 220 is a ferromagnetic metal rod, such as an iron rod. A magnetic member installation groove can be provided at the bottom of the assembly hole 150, and the magnetic member 160 is arranged in the magnetic member installation groove. The diameter of the magnetic member installation groove can be larger than the inner diameter of the assembly hole 150 to ensure that the magnetic member 160 will not fall off from the assembly hole 150. When the tooling body 100 and the front strut assembly 200 are assembled, only need to insert the piston rod 220 of the front strut assembly 200 into the assembly hole 150 of the tooling body 100, and the magnetic member 160 can adsorb the piston rod 220. When disassembly is required, only need to pull the front strut assembly 200 outward with force. When the external force applied exceeds the adsorption force between the magnetic member 160 and the piston rod 220, the front strut assembly 200 will be separated from the tooling body 100.

[0060] By providing the magnetic member 160 in the assembly hole 150 in the embodiment of the present application, the detachable connection between the assembly hole 150 and the piston rod 220 is realized, thus ensuring that the tooling body 100 and the front strut assembly 200 have a relatively fast installation and disassembly speed.

[0061] In some possible implementations, a threaded section may be provided in the assembly hole 150 for threaded connection with the piston rod 220.

[0062] Exemplarily, in the embodiments of the present application, an internal thread may also be machined in the assembly hole 150, and the internal thread is adapted to the existing external thread on the piston rod 220. When assembling the tooling body 100 and the front strut assembly 200, only need to insert the piston rod 220 of the front strut assembly 200 into the assembly hole 150 of the tooling body 100, and by rotating the front strut assembly 200 or the tooling body 100, the assembly hole 150 is threadedly connected with the piston rod 220. When disassembly is required, only need to rotate the front strut assembly 200 or the tooling body 100 in the reverse direction to separate the assembly hole 150 from the piston rod 220.

[0063] In the embodiments of the present application, by providing a threaded section in the assembly hole 150, the threaded section is used to connect with the existing thread on the piston rod 220, making full use of the existing structure on the front strut assembly 200, which is beneficial to reducing the number of components.

[0064] Please continue to refer to Figure 1 and Figure 4 , in some embodiments, an avoidance groove 170 is further provided on the first surface 110 of this embodiment, the assembly hole 150 is located in the avoidance groove 170, and the avoidance groove 170 is adapted to the protrusion on the front strut assembly 200. It can be understood that the assembly hole 150 may be located on the bottom wall of the avoidance groove 170, or, a corresponding protrusion structure may be provided in the avoidance groove 170, and the assembly hole 150 may be provided on the protrusion structure. Its specific structure can be determined according to the corresponding structure on the end of the front strut assembly 200 to ensure that the tooling body 100 and the end of the front strut assembly 200 can be closely attached.

[0065] In the embodiments of the present application, by providing the avoidance groove 170, the tooling body 100 can be attached to the end of the front strut assembly 200, so that the stress can be dispersed, reducing the situation of single-point force on the tooling body 100, which is beneficial to improving the strength of the overall structure.

The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application accordingly.
