Description

Technical Field

[0001] This application relates to the field of vehicle manufacturing technology, and in particular to a suspension control arm with quick-release function and a vehicle. Background Technology

[0002] Suspension arms typically play a crucial role in a vehicle's suspension system, connecting the wheel axles to the frame or body to ensure stability and handling during driving. Existing suspension arm bushings use an interference fit with the arm body, requiring pressure equipment to press the bushing into the arm body during assembly. Once pressed in, the bushing cannot be removed; forcibly removing it will damage the bushing and the arm itself.

[0003] During the early stages of vehicle development, such as suspension tuning, various combinations of bushings with different stiffnesses are typically required. However, existing press-fit bushing and control arm bodies cannot be replaced on-site. Therefore, current tuning methods generally involve preparing multiple suspension control arms in advance, each using bushings with different stiffnesses, and each control arm requiring individual on-vehicle tuning. If many bushings need tuning, multiple additional control arms must be manufactured, increasing tuning costs, wasting materials, and adding time. Later, during after-sales maintenance, existing suspension control arms often need complete replacement, increasing user maintenance costs. Furthermore, often only the bushings wear out, without requiring replacement of the control arm body itself, again resulting in material waste.

[0004] Therefore, a suspension control arm with quick-release function needs to be designed to solve the above problems. Summary of the Invention

[0005] In view of this, in order to overcome the shortcomings of the prior art, the present invention provides a suspension control arm and vehicle with quick release function, which effectively solves the problems of material waste, increased adjustment or maintenance time and cost in the early stage of vehicle adjustment and later maintenance of the existing suspension control arm.

[0006] According to a first aspect of the present invention, a suspension control arm with a quick-release function is provided, wherein the suspension control arm with a quick-release function includes a bushing body and a control arm body, and mounting positions are provided at both the end and the middle of the control arm body. A first connecting thread is provided on the inner sidewall of the mounting position. The bushing body includes a body portion and a boss portion. The boss portion is located at one end of the body portion, and a second connecting thread is provided on the outer wall of the body portion. The boss portion protrudes outward along the radial direction of the body portion. The two ends of the bushing body are respectively engaged with the two opposite end faces of the mounting position by snap-fit ​​members and the boss portion. The bushing body is detachably mounted to the mounting position by the first connecting thread and the second connecting thread.

[0009] Preferably, the body portion of the first bushing body has a snap-fit ​​groove, which is located at the end of the body portion away from the boss portion. The first connector includes a snap-fit ​​member and an adjusting member. When the first bushing body is installed in the first mounting position, the adjusting member is located between the first mounting position and the boss portion, and the snap-fit ​​member is located in the snap-fit ​​groove and abuts against the first mounting position.

[0010] Preferably, the second connector is a locking member, and the inner sidewall of the locking member is provided with a third connecting thread. When the second bushing body is installed in the second mounting position, the locking member is fitted onto the second bushing body, and one end of the locking member abuts against the second mounting position.

[0011] Preferably, the snap-fit ​​groove is formed as a snap-fit ​​groove, the snap-fit ​​element is a snap-fit ​​spring, and the adjusting element is an adjusting shim. When the first bushing body is installed in the first mounting position, the snap-fit ​​spring and the adjusting shim are respectively snapped into the two opposite ends of the first mounting position.

[0012] Preferably, the locking element is a locking ring, the inner sidewall of the locking ring is provided with the third connecting thread, and the outer sidewall of the locking ring is provided with a split groove.

[0013] Preferably, there are two slots, which are disposed opposite to each other on the outer side wall of the locking ring.

[0014] Preferably, the swing arm body includes a first end, a second end, and a third end, the first end and the third end are respectively disposed, the second end is disposed in the middle of the swing arm body, the first end and the second end are provided with the mounting position, and the third end is connected to the vehicle body.

[0015] According to a second aspect of the invention, a vehicle is provided, wherein the vehicle includes a suspension control arm with a quick-release function as described above.

[0016] According to the present invention, the suspension swing arm with quick-release function, through the cooperation of the bushing body and the swing arm body, allows the bushing body to be easily and quickly removed from the swing arm body and replaced. Thus, whether in the early stage of research and development or in the later stage of maintenance, only the bushing body needs to be replaced to achieve research and development testing and maintenance, avoiding waste of materials, shortening research and development and maintenance time, and reducing research and development and maintenance costs.

[0030] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0031] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0032] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0033] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as the second component, assembly, region, layer, or part may also be referred to as the second component, assembly, region, layer, or part.

[0034] For ease of description, spatial relation terms such as “above,” “upper,” “below,” and “lower” are used herein to describe the relationship between one element and another, as shown in the accompanying drawings. Such spatial relation terms are intended to include not only the orientation depicted in the drawings but also different orientations of the device during use or operation.

[0037] The features of the examples described herein can be combined in various ways that will be apparent upon understanding the disclosure of this application. Furthermore, although the examples described herein have a wide variety of constructions, other constructions are possible, as will be apparent upon understanding the disclosure of this application.

[0038] According to a first aspect of the present invention, a suspension control arm with a quick-release function is provided, such as Figures 1 to 9As shown, the quick-release suspension arm is used in the vehicle's suspension system. The quick-release suspension arm includes an arm body 1 and a plurality of bushing bodies disposed on the arm body 1.

[0039] In the following description, reference will be made to Figures 1 to 9 This section describes the detailed structure of the control arm body 1 and bushing body of the suspension control arm with quick-release function.

[0040] like Figures 1 to 6 As shown, in this embodiment, mounting positions are provided at both the end and the middle of the swing arm body 1 (for distinction and ease of description, for example, in...). Figure 2 The first mounting position 101 and the second mounting position 102 are shown in the diagram. These mounting positions can be used to mount the bushing body. The inner wall of each mounting position has a first connecting thread (not shown due to view limitations) for quick release. The mounting position can be formed as a through hole, and the bushing body (for distinction and ease of description, for example, in...) Figure 1 The first bushing body 2 and the second bushing body 3 are disposed inside the through hole. The through hole may include two corresponding ends, the end faces of which are arranged back to back. The two ends of the bushing body can be respectively engaged with these two end faces to fix the axis and prevent the bushing body from coming out. Specifically, the bushing body includes a body portion and a boss portion (in order to correspond with the first bushing body 2 and the second bushing body 3, the body portion is located on...). Figure 3 and Figure 5 The first body portion 201 and the second body portion 301 are respectively located in the middle, and the boss portion is in Figure 3 and Figure 5 The bushing body (represented by the first boss portion 202 and the second boss portion 302) can be understood as the main body of the bushing body. The body includes two ends, one of which has a boss portion. The boss portion protrudes radially outward from one end of the body and can engage with one end face of the mounting position when the bushing body is installed in the mounting position. The outer wall of the body has a second connecting thread corresponding to the first connecting thread. The bushing body is detachably installed in the mounting position via the first and second connecting threads. Due to the connecting threads, the bushing body can be removed from the control arm body 1. This allows for the replacement of bushing bodies with different stiffnesses during early development without replacing the control arm body 1. Similarly, during later maintenance, only the bushing body needs to be replaced without replacing the entire suspension control arm.

[0041] Furthermore, the two ends of the bushing body are respectively engaged with the two opposite end faces of the mounting position by snap-fit ​​parts and bosses to achieve axial fixation, where the axial direction refers to the axial direction of the bushing body.

[0042] In summary, the quick-release suspension arm, through the cooperation of the bushing body and the arm body 1, allows the bushing body to be easily and quickly removed from and replaced by the arm body 1. Thus, whether in the early stage of research and development or in the later stage of maintenance, only the bushing body needs to be replaced to achieve research and development testing and maintenance, avoiding waste of materials, shortening research and development and maintenance time, and reducing research and development and maintenance costs.

[0043] Preferably, such as Figures 1 to 6 As shown, in the embodiment, there are two bushing bodies, namely the first bushing body 2 and the second bushing body 3. Therefore, in the early research and development design, for example, the first bushing body 2 has n kinds of stiffness and the second bushing body 3 has m kinds of stiffness, that is, n*m combinations can be achieved by using one swing arm body 1, avoiding the need to prepare n*m ​​sets of suspension swing arms in the original research and development design, reducing the waste of materials and reducing the research and development cost.

[0044] Preferably, such as Figures 1 to 6 As shown, in this embodiment, the middle part of the swing arm body 1 is the first mounting position 101, and the end of the swing arm body 1 is the second mounting position 102. The first mounting position 101 is perpendicular to the second mounting position 102. The swing arm body 1 can be a common structure in the prior art, which includes three connecting ends that can be connected to the vehicle body, wheels, and suspension system, respectively. Therefore, only two bushing bodies need to be provided at the end and middle of the swing arm body 1. Since the installation space and installation position of the first mounting position 101 and the second mounting position 102 are different in this embodiment, the installation method of the bushing bodies installed at these two locations is somewhat different. However, in practical applications, depending on the specifications of the swing arm body 1, the operator can select a suitable installation method according to the specific structure of the swing arm body 1. For example, both can be installed using the first bushing body 2 as described below, or both can be installed using the second bushing body 3 as described below, or a combination of the first bushing body 2 and the second bushing body 3.

[0045] Preferably, such as Figures 1 to 6 As shown, in this embodiment, the bushing body may include a first bushing body 2 disposed at a first mounting position 101 and a second bushing body 3 disposed at a second mounting position 102. The first bushing body 2 is snapped into the first mounting position 101 by a first connector, and the second bushing body 3 is snapped into the second mounting position 102 by a second connector. The first bushing body 2 and the second bushing body 3 may be snapped into their respective mounting positions by different connectors.

[0046] Preferably, such as Figure 3 and Figure 4As shown, in this embodiment, the body portion (i.e., the first body portion 201) of the first bushing body 2 has a snap-fit ​​groove, which is located at the end of the first body portion 201 away from the first boss portion 202. The first connecting member includes a snap-fit ​​member and an adjusting member. When the first bushing body 2 is installed in the first mounting position 101, the adjusting member is located between the first mounting position 101 and the first boss portion 202, and the snap-fit ​​member is located in the snap-fit ​​groove, abutting against the first mounting position 101. The first bushing body 2 is snapped into the first mounting position 101 through the cooperation of the snap-fit ​​member, the adjusting member, and the first boss portion 202, which also achieves axial fixation of the first bushing body 2.

[0047] Preferably, such as Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, in this embodiment, the snap-fit ​​groove is formed as a snap-fit ​​groove 203, the snap-fit ​​element is a snap-fit ​​spring 4, and the adjusting element is an adjusting shim 5. When the first bushing body 2 is installed in the first mounting position 101, the snap-fit ​​spring 4 and the adjusting shim 5 are respectively snapped into the two opposite ends of the first mounting position 101. Since the first bushing body 2 is vertically installed relative to the swing arm body 1 and has a lot of installation space, the snap-fit ​​spring 4 and the adjusting shim 5 can be used to fix both ends to ensure axial stability.

[0048] Preferably, such as Figure 5 and Figure 6 As shown, in this embodiment, the second connector is a locking member. The inner sidewall of the locking member is provided with a third connecting thread. When the second bushing body 3 is installed in the second mounting position 102, the locking member is fitted onto the second bushing body 3, and one end of the locking member abuts against the second mounting position 102.

[0049] Preferably, such as Figure 5 , Figure 6 and Figure 9 As shown, in this embodiment, the locking element is a locking ring 6. The inner wall of the locking ring 6 is provided with a third connecting thread, and the outer wall of the locking ring 6 is provided with a split groove 601. The locking ring 6 is also threadedly connected to the second bushing body 3, and can lock one end of the second bushing body 3 to prevent the second bushing body 3 from shifting. The other end of the second bushing body 3 is engaged with the swing arm body 1 through the second boss portion 302.

[0050] Preferably, such as Figure 9 As shown, in this embodiment, there are two slots 601, which are disposed opposite to each other on the outer side wall of the locking ring 6. The slots 601 can be used to assist in locking and facilitate operation by the operator.

[0051] Preferably, such as Figure 1 and Figure 2As shown, in an embodiment, the swing arm body 1 may include a first end 103, a second end 104 and a third end 105. The first end 103 and the third end 105 are correspondingly arranged. The second end 104 is located in the middle of the swing arm body 1. The first end 103 and the second end 104 are provided with mounting positions, namely the first mounting position 101 and the second mounting position 102, respectively. The third end 105 is connected to the vehicle body through a ball joint 7.

[0052] The quick-release suspension arm is used as follows: Place an adjusting shim 5 on the end of the first bushing body 2 with the first boss 202, then screw it into the first mounting position 101 via a threaded connection. At this point, the adjusting shim 5 is located between the first boss 202 and the first mounting position 101. Then, use a retaining ring 4 to engage the end without the first boss 202 to achieve axial fixation. Circumferential fixation is achieved via a threaded connection. Screw the second bushing body 3 into the second mounting position 102 via a threaded connection until the second boss 302 abuts against the end face of the second mounting position 102. Then, fit a locking ring 6 onto the end of the second bushing body 3 without the second boss 302, using the locking ring 6 and the second boss 302 to achieve locking and fixation. During the early research and development phase, operators can select first bushing bodies 2 and second bushing bodies 3 with different stiffnesses, and assemble them to the mounting position as shown above. When replacing them, a threaded connection can be used for quick replacement, avoiding the problem that the original press-fit bushing body cannot be replaced. In the later vehicle maintenance, a threaded connection can also be used for quick replacement of the bushing body, so that the swing arm body 1 does not need to be replaced.

[0053] The quick-release suspension arm allows the bushing body to be easily and quickly removed from and replaced by the control arm body through the cooperation of the bushing body and the control arm body. Thus, whether in the early stage of research and development or in the later stage of maintenance, only the bushing body needs to be replaced to achieve research and development testing and maintenance, avoiding waste of materials, shortening research and development and maintenance time, and reducing research and development and maintenance costs.

[0054] Furthermore, according to a second aspect of the present invention, a vehicle is provided, the vehicle including a suspension control arm with a quick-release function as described above. During the early stages of research and development, the use of this suspension control arm with a quick-release function can accelerate the development process and reduce development costs. After the vehicle leaves the factory and is in a maintenance state, only the bushing body needs to be replaced, thereby reducing maintenance costs for users and improving the user experience.

[0055] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto.
