[0001] The present application relates to the technical field of vehicle manufacturing, and in particular to a suspension swing arm with a quick-release function and a vehicle. Background Art

[0002] Suspension swing arms usually play an important role in vehicle suspension systems. They are responsible for connecting the wheel axle and the frame or body to ensure the stability and controllability of the vehicle during driving. The existing suspension swing arm bushings are interference fit with the swing arm body. During assembly, a pressure device is required to press the bushing into the swing arm body. After the bushing is pressed in, it cannot be disassembled. Forced disassembly will cause damage to the bushing body and the arm body.

[0003] During the early development of a vehicle, for example, when adjusting the suspension, various combinations of bushings with different stiffness are generally required for adjustment. However, the bushings and swing arm bodies assembled by the existing press-fit method cannot be replaced in the adjustment field. Therefore, the existing adjustment method generally prepares multiple suspension swing arms in advance, and each suspension swing arm uses bushings with different stiffness. At the same time, each suspension swing arm needs to be installed and adjusted separately. If there are many bushings that need to be adjusted, it is necessary to make multiple suspension swing arms additionally, which will increase the adjustment cost, waste equipment and take more time. When the vehicle is in after-sales maintenance at a later stage, the existing suspension swing arm needs to be completely replaced during maintenance, which will also cause the user's maintenance cost to increase. In addition, usually the bushing is worn and the swing arm body does not need to be replaced, which also causes a waste of equipment.

[0038] According to a first aspect of the present invention, a suspension swing arm with a quick release function is provided. Figures 1 to 9As shown, the suspension swing arm with quick-release function is used in a suspension system of a vehicle, and the suspension swing arm with quick-release function comprises a swing arm body 1 and a plurality of bushing bodies arranged on the swing arm body 1 .

[0039] In the following description, reference will be made to Figures 1 to 9 The detailed structures of the swing arm body 1 and the bushing body of the suspension swing arm with quick release function are described in detail.

[0040] like Figures 1 to 6 As shown, in the embodiment, the end and middle of the swing arm body 1 are both provided with mounting positions (for the purpose of distinction and convenience of description, for example, Figure 2 The first installation position 101 and the second installation position 102 are shown in the figure. The installation position can be used for installing the bushing body. The inner side wall of the installation position is provided with a first connecting thread (not shown due to the view reason) for quick release. The installation position can be formed as a through hole, and the bushing body (for the purpose of distinction and convenience of description, for example, Figure 1 The first bushing body 2 and the second bushing body 3 are arranged inside the through hole. The through hole may include two corresponding ends. The end faces of the two ends are arranged back to back. The two ends of the bushing body can be respectively engaged with the two end faces to fix the axis and prevent the bushing body from falling out. Specifically, the bushing body includes a body part and a boss part (in order to correspond to the first bushing body 2 and the second bushing body 3, the body part is Figure 3 and Figure 5 In the figure, the first body part 201 and the second body part 301 are respectively provided, and the boss part is provided at Figure 3 and Figure 5 In the figure, they are the first boss portion 202 and the second boss portion 302 respectively), the main body portion can be understood as the main body of the bushing body, and the main body portion includes two ends, one of which is provided with a boss portion, that is, the boss portion is provided at one end of the main body portion, and the boss portion protrudes radially outward along the main body portion, and when the bushing body is installed in the mounting position, the boss portion can be clamped on an end face of the mounting position. The outer wall of the main body portion is provided with a second connecting thread corresponding to the first connecting thread, and the bushing body is detachably installed in the mounting position through the first connecting thread and the second connecting thread. Due to the setting of the connecting thread, the bushing body can be disassembled from the swing arm body 1, so that in the early development, bushing bodies with different stiffness can be replaced without replacing the swing arm body 1, and in the later maintenance, only the bushing body can be replaced without replacing the entire suspension swing arm.

[0041] Furthermore, both ends of the bushing body are respectively clamped to two end surfaces facing away from each other at the installation position through the clamping parts and the boss parts to achieve fixation in the axial direction, where the axial direction refers to the axial direction of the bushing body.

[0042] To sum up, the suspension swing arm with quick-release function cooperates with the bushing body and the swing arm body 1 so that the bushing body can be easily and quickly removed from the swing arm body 1 and replaced. Therefore, whether in the early stage of research and development and design or in the later stage of maintenance, only the bushing body can be replaced to realize research and development testing and maintenance, avoiding waste of equipment, shortening research and development and maintenance time, and reducing research and development and maintenance costs.

[0043] Preferably, if Figures 1 to 6 As shown, in the embodiment, two bushing bodies are included, namely a first bushing body 2 and a 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 kinds of combinations can be achieved when one swing arm body 1 is used, avoiding the need to prepare n*m ​​sets of suspension swing arms in the original research and development design, reducing equipment waste and reducing research and development costs.

[0044] Preferably, if Figures 1 to 6 As shown, in the embodiment, the middle part of the swing arm body 1 is the first installation position 101, the end of the swing arm body 1 is the second installation position 102, and the first installation position 101 is perpendicular to the second installation position 102. The swing arm body 1 can be a common structure in the prior art, which includes three connecting ends, which can be connected to the vehicle body, the wheel and the suspension system respectively, so it is only necessary to set two bushing bodies at the end and the middle of the swing arm body 1. Since in the embodiment, the installation space and installation position of the first installation position 101 and the second installation position 102 are different, the installation method of the bushing bodies installed at these two places is somewhat different. However, in actual application, according to the different 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, such as the installation method of the first bushing body 2 described below, or the installation method of the second bushing body 3 described below, or the installation method of the first bushing body 2 and the second bushing body 3 combined.

[0045] Preferably, if Figures 1 to 6 As shown, in the 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 being clamped to the first mounting position 101 by a first connector, and the second bushing body 3 being clamped to the second mounting position 102 by a second connector. The first bushing body 2 and the second bushing body 3 may be clamped to corresponding mounting positions by different clamping members.

[0046] Preferably, if Figure 3 and Figure 4As shown, in the embodiment, the main body portion (i.e., the first main body portion 201) of the first bushing body 2 is provided with a clamping groove, which is arranged at one end of the first main body portion 201 away from the first boss portion 202. The first connecting member includes a clamping member and an adjusting member. When the first bushing body 2 is installed in the first installation position 101, the adjusting member is arranged between the first installation position 101 and the first boss portion 202, and the clamping member is arranged in the clamping groove, and the clamping member abuts the first installation position 101. The first bushing body 2 is clamped to the first installation position 101 through the cooperation of the clamping member, the adjusting member and the first boss portion 202, and the axial fixation of the first bushing body 2 can also be achieved.

[0047] Preferably, if Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, in the embodiment, the clamping groove is formed as a clamping spring groove 203, the clamping member is a clamping spring 4, and the adjusting member is an adjusting gasket 5. When the first bushing body 2 is installed in the first installation position 101, the clamping spring 4 and the adjusting gasket 5 are respectively clamped at two opposite ends of the first installation position 101. Since the first bushing body 2 is vertically installed relative to the swing arm body 1 and has more installation space, the clamping spring 4 and the adjusting gasket 5 can be used to fix the two ends to ensure axial stability.

[0048] Preferably, if Figure 5 and Figure 6 As shown, in the embodiment, the second connecting member is a locking member, and the inner wall of the locking member is provided with a third connecting thread. When the second bushing body 3 is installed in the second installation position 102, the locking member is sleeved on the second bushing body 3, and one end of the locking member abuts against the second installation position 102.

[0049] Preferably, if Figure 5 , Figure 6 and Fig. 9 As shown, in the embodiment, the locking member is a locking ring 6, the inner side wall of the locking ring 6 is provided with a third connecting thread, and the outer side 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, and the other end of the second bushing body 3 is clamped with the swing arm body 1 through the second boss portion 302.

[0050] Preferably, if Fig. 9 As shown, in the embodiment, there are two split grooves 601, and the two split grooves 601 are oppositely arranged on the outer side wall of the locking ring 6. The split grooves 601 can be used to assist locking, which is convenient for operators to operate.

[0051] Preferably, if 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 arranged correspondingly, the second end 104 is arranged in the middle of the swing arm body 1, the first end 103 and the second end 104 are provided with installation positions, which are respectively a first installation position 101 and a second installation position 102, and the third end 105 is connected to the body of the vehicle through a ball head 7.

[0052] The use of the suspension swing arm with quick release function is as follows: the end of the first bushing body 2 provided with the first boss portion 202 is placed with an adjustment gasket 5, and then screwed into the first installation position 101 by means of threaded connection. At this time, the adjustment gasket 5 is located between the first boss portion 202 and the first installation position 101, and then the end without the first boss portion 202 is clamped with a retaining ring 4 to achieve axial fixation, and the circumferential direction is fixed by threaded connection. The second bushing body 3 is screwed into the second installation position 102 by means of threaded connection until the second boss portion 302 abuts against the end surface of the second installation position 102, and then the locking ring 6 is sleeved on the end of the second bushing body 3 without the second boss portion 302, and the locking and fixing is achieved by using the locking ring 6 and the second boss portion 302. During the early stage of research and development and design, the operator can select the first bushing body 2 and the second bushing body 3 with different stiffness, and install the first bushing body 2 and the second bushing body 3 with different stiffness to the installation position in the manner shown above. When replacing, they can be quickly replaced by means of threaded connection, avoiding the problem that the original press-fitting cannot replace the bushing body; during the later vehicle maintenance, the bushing body can also be quickly replaced by means of threaded connection, so there is no need to replace the swing arm body 1.

[0053] The suspension swing arm with quick-release function cooperates with the bushing body and the swing arm body so that the bushing body can be easily and quickly removed from the swing arm body and replaced. Therefore, whether in the early stage of research and development and design or in the later stage of maintenance, only the bushing body can be replaced to achieve research and development testing and maintenance, thus avoiding waste of equipment, shortening research and development and maintenance time, and reducing research and development and maintenance costs.

[0054] In addition, according to a second aspect of the present invention, a vehicle is provided, the vehicle comprising the suspension swing arm with quick release function as described above. In the early stage of the research and development design of the vehicle, the suspension swing arm with quick release function can be used to speed up the research and development progress and reduce the research and development cost.
