The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0073] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0074] Example

[0075] Figure 1 This is a top view of a vehicle 1000 according to an embodiment of this application.

[0076] See Figure 1 This embodiment provides a vehicle 1000, which may be, for example, a fuel vehicle (such as a gasoline vehicle, a diesel vehicle, etc.), an electric vehicle (such as a pure electric vehicle, a fuel cell vehicle), or a hybrid electric vehicle.

[0077] The vehicle 1000 includes a body 1100, wheels 1200, and a suspension 1300. The suspension 1300 connects the wheels 1200 and the body 1100, and can buffer vibrations from the road surface transmitted to the body 1100 through the wheels 1200, thereby improving the driving experience. It should be noted that... Figure 1 This is only used to illustrate the relative positions of the body 1100, wheels 1200 and suspension 1300, and does not represent the actual structure of the body 1100, wheels 1200 and suspension 1300.

[0078] In this embodiment, the suspension 1300 can be a front suspension or a rear suspension.

[0079] In some embodiments, bushings are provided at the connection points between the components of the suspension 1300 or at the connection points between the suspension 1300 and the vehicle body 1100 to provide a certain buffering and vibration isolation function.

[0080] Figure 2 for Figure 1 A partial structural schematic diagram of the suspension 1300 in the illustrated embodiment; Figure 3 for Figure 1 Partial structural cross-sectional view of the suspension 1300 in the illustrated embodiment; Figure 4 for Figure 1 A partial structural cross-sectional view of the suspension 1300 in the illustrated embodiment.

[0081] See Figure 2 to Figure 4This embodiment provides a suspension 1300, including a first component 200, a bushing 100, a second component 300, and fasteners 400 (such as bolts). The bushing 100 includes an outer tube 10, an inner tube 20, and an elastic body 30. The inner tube 20 includes a tube body 21 and a reinforcing end 22. The tube body 21 defines a first through hole 211a. The reinforcing end 22 is separately disposed from the tube body 21 and connected to one end of the tube body 21. The reinforcing end 22 is provided with a second through hole 22a, which is coaxially disposed with and communicates with the first through hole 211a. The end face of the reinforcing end 22 away from the tube body 21 is a conical surface 2211. The first component 200 is provided with a mounting hole 200a, through which the outer tube 10 passes. The second component 300 is provided with a tapered hole 300a and a connecting hole 300b. The tapered hole 300a mates with the end of the reinforcing end 22 away from the tube body 21, and the connecting hole 300b is axially connected to the end of the tapered hole 300a away from the tube body 21. Fasteners 400 pass through the first through hole 211a, the second through hole 22a, and the connecting hole 300b respectively to fasten the first component 200 and the second component 300 together.

[0082] Thus, the bushing 100 is installed in the mounting hole 200a of the first component 200, and the bushing 100 is connected to the second component 300 by fasteners 400 passing through the inner tube 20 of the bushing 100 and the second component 300. The inner tube 20 of the bushing 100 contacts the second component 300 through the reinforcing end 22, and because the tapered surface 2211 of the reinforcing end 22 contacts and fits into the tapered hole 300a of the second component 300, the contact area between the inner tube 20 of the bushing 100 and the second component 300 is increased, reducing the risk of crushing between them, and making the contact surface between the bushing 100 and the second component 300 more uniformly stressed in all directions, thereby improving the connection reliability. In use, when the bushing 100 is subjected to lateral impact force, the end of the reinforcing end 22 with the conical surface 2211 provides lateral support force. Since the reinforcing end 22 and the tube body 21 are set separately, the surface strength (or hardness) of the conical surface 2211 of the reinforcing end 22 can be flexibly controlled. For example, the material of the reinforcing end 22 can be changed or the surface of the conical surface 2211 can be treated, so that the bushing 100 can resist the lateral impact force of higher load without deformation, thereby making the connection between the first component 200 and the second component 300 stable and reliable.

[0083] It should be noted that the reinforced end 22 and the tube body 21 are set separately, meaning that the reinforced end 22 and the tube body 21 are formed separately and assembled together by means of interference fit or other methods.

[0084] During assembly, the bushing 100 is first pressed into the mounting hole 200a of the first component 200 by a press-fitting process. Then, the fasteners 400 are passed through the inner tube 20 and the second component 300 respectively to connect and install the first component 200 and the second component 300 together.

[0085] Optionally, such as Figure 2 As shown, the first component 200 can be a control arm 201, and the second component 300 can be a steering knuckle 301. The end of the control arm 201 away from the steering knuckle 301 is used to connect to the vehicle body 1100 (such as a frame or subframe, see...). Figure 1 In use, when the wheel 1200 is subjected to a lateral impact (such as when the vehicle 1000 sideslips and hits a curb), the impact force is transmitted to the control arm 201 through the steering knuckle 301. The bushing 100, as the connecting part between the control arm 201 and the steering knuckle 301, is subjected to the impact force. Since the bushing 100 is in contact with the second component 300 through the conical surface 2211, and the reinforced end 22 is provided to improve the surface strength of the conical surface 2211, the resistance of the contact surface between the bushing 100 and the second component 300 to lateral impact force is improved, making the contact surface less prone to deformation. Therefore, the service life of the parts and driving stability are extended, and the risk of loosening or abnormal noise at the connection between the first component 200 and the second component 300 is reduced.

[0086] In some embodiments, such as Figure 3 As shown, the fastener 400 includes a screw 410 and a bolt head 420. The screw 410 passes through the inner tube 20 and the second component 300, respectively. The end of the screw 410 away from the second component 300 extends out of the inner tube 20 and connects to the bolt head 420. The suspension 1300 also includes a washer 500, which is sleeved on the outside of the screw 410 and located between the bolt head 420 and the inner tube 20 to protect the surface of the inner tube 20 near the bolt head 420 and improve the firmness and stability of the fastening connection. Optionally, the surface of the inner tube 20 near the bolt head 420 is configured as a plane.

[0087] In some embodiments, such as Figure 4 As shown, the cone angle α of the tapered hole is smaller than the cone angle β of the tapered surface, so that the reinforcing end 22 is interference-fitted with the tapered hole 300a under the preload provided by the fastener 400. For example, the cone angle α of the tapered hole is 118 degrees, and the cone angle β of the tapered surface is 120 degrees.

[0088] It should be noted that because the reinforcing end 22 and the tube body 21 are separate, the surface strength (or hardness) of the reinforcing end 22 can be easily controlled, ensuring that the material strength of the reinforcing end 22 is greater than the material strength of the wall of the tapered hole 300a. This allows the preload provided by the fastener 400 to press the reinforcing end 22 into the second component 300, achieving an interference fit. For example, the reinforcing end 22 can be made of a high-strength material such as steel, while the second component 300 can be made of a lower-strength material such as aluminum alloy. This allows the installed reinforcing end 22 to embed into the tapered hole 300a, achieving a more stable and reliable connection. It should be noted that the interference fit of the reinforcing end 22 is a small amount, and the reinforcing end 22 and the tapered hole 300a must not yield when pressed in.

[0089] Since the surface strength (or hardness) of the reinforced end 22 can be flexibly controlled, in order to further improve the hardness and surface strength of the conical surface 2211, heat treatment can also be performed on the conical surface 2211 of the reinforced end 22.

[0090] Figure 5 for Figure 1 A schematic diagram of the bushing 100 in the illustrated embodiment; Figure 6 for Figure 1 A cross-sectional view of the bushing 100 in the illustrated embodiment.

[0091] See Figure 5 and Figure 6 In this embodiment, the bushing 100 includes an outer tube 10, an inner tube 20, and an elastomer 30. As mentioned above, the inner tube 20 includes a tube body 21 and a reinforcing end 22. The tube body 21 is disposed inside the outer tube 10, defining a filling space 100a between the tube body 21 and the outer tube 10. The tube body 21 defines a first through hole 211a. The reinforcing end 22 is separately disposed from the tube body 21 and connected to one end of the tube body 21. The reinforcing end 22 has a second through hole 22a, which is coaxially disposed with and communicates with the first through hole 211a. The end face of the reinforcing end 22 away from the tube body 21 is a conical surface 2211. The elastomer 30 fills the filling space 100a and is connected between the outer tube 10 and the tube body 21.

[0092] The bushing 100, by providing a tapered surface 2211 on the reinforcing end 22, increases the contact area between the reinforcing end 22 and the connecting component (such as the second component 300 in this embodiment), reducing the risk of crushing. Furthermore, the tapered surface 2211 and the connecting component experience more uniform stress in all directions, further improving connection reliability. Moreover, by separating the reinforcing end 22 from the tube body 21, it is easier to control the strength of the reinforcing end 22. For example, the reinforcing end 22 can be made of a high-strength material, thereby improving the bushing 100's resistance to bending and deformation, and thus enhancing the reliability of the bushing 100 connection. A first through hole 211a and a second through hole 22a are provided to allow the fastener 400 to pass through the inner tube 20. By being disposed on the elastomer 30, since the elastomer 30 can deform during use (such as when the vehicle 1000 is in motion), relative movement between the first component 200 and the second component 300 is allowed, and the elastomer 30 provides cushioning and vibration isolation, absorbing vibrations generated by road surface excitation from the wheel 1200, thereby improving driving stability and ride comfort.

[0093] Alternatively, the conical surface 2211 can be machined by processes such as machining, cold heading, or casting.

[0094] In some embodiments, the tube body 21 is made of a first material, and the reinforcing end 22 is made of a second material. The strength of the second material is greater than that of the first material to improve the mechanical properties of the reinforcing end 22, such as increasing its resistance to bending moment and making it less prone to deformation when subjected to lateral force compression. This improves the structural strength of the connection between the reinforcing end 22 and the second component 300, making the connection more reliable. Furthermore, the first material can be a lightweight material, which helps reduce weight and meet lightweight requirements. For example, since the battery and motor of new energy vehicles make the vehicle heavy, the bushing 100 can be applied to new energy vehicles to reduce weight. Optionally, the first material is aluminum alloy, and the second material is steel.

[0095] In some embodiments, such as Figure 6As shown, the pipe body 21 includes a first main body portion 211 and a first mating portion 212 arranged axially. The first main body portion 211 defines a first through hole 211a. The first mating portion 212 is located at the end of the first main body portion 211 near the reinforcing end 22. The first mating portion 212 has a mating hole 212a that communicates axially with the first through hole 211a, and the diameter of the mating hole 212a is larger than the diameter of the first through hole 211a. The reinforcing end 22 includes a second main body portion 221 and a second mating portion 222 arranged axially. The second mating portion 222 fits into the mating hole 212a. The second main body portion 221 is located at the end of the second mating portion 222 away from the first main body portion 211, and the second main body portion 221 is axially attached to the end of the first mating portion 212 away from the first main body portion 211. The end of the second main body portion 221 away from the second mating portion 222 has a tapered surface 2211. Thus, by inserting the second mating portion 222 of the reinforcing end 22 into the first mating portion 212 of the tube body 21, the reinforcing end 22 is connected to the tube body 21. Furthermore, since the second main body portion 221 of the reinforcing end 22 is located outside the inner tube 20, it is beneficial to increase the area of ​​the conical surface 2211, thereby reducing the pressure on the conical surface 2211 when it acts as a contact surface and improving the reliability of the contact connection. Because the second main body portion 221 is axially fitted to the first mating portion 212, the fastener 400 (see...) Figure 4 The preload provided enables the reinforced end 22 to be pressed more reliably against the second component 300.

[0096] It should be noted that the first main body 211 and the first mating part 212 can be integrally formed or separately provided. The second main body 221 and the second mating part 222 can be integrally formed or separately provided.

[0097] Optionally, the second mating part 222 is interference-fitted with the mating hole 212a to ensure a reliable connection between the tube body 21 and the reinforcing end 22. Optionally, the second mating part 222 can be press-fitted into the mating hole 212a using a press-fitting process.

[0098] In some embodiments, such as Figure 4 and Figure 6 As shown, a gap 20a is defined axially between the second mating part 222 and the first main body part 211. Thus, when the second main body part 221 abuts against the first mating part 212 axially, the second mating part 222 will not abut against the first main body part 211. Therefore, the second main body part 221 can fit more tightly against the first mating part 212 axially, allowing the preload provided by the fastener 400 to better press the reinforcing end 22 into the tapered hole 300a, making the connection more reliable.

[0099] In some embodiments, such as Figure 6As shown, the wall thickness of the second mating part 222 is less than the wall thickness of the first mating part 212. This increases the contact area between the first mating part 212 and the second main body part 221, thereby providing a reliable contact surface for the first mating part 212 and the second main body part 221 and reducing the pressure on the contact surface. It should be noted that the wall thickness of the second mating part 222 refers to the radial distance between the inner and outer circumferential surfaces of the second mating part 222, and the wall thickness of the first mating part 212 refers to the radial distance between the inner and outer circumferential surfaces of the first mating part 212.

[0100] In some embodiments, such as Figure 6 As shown, the second mating part 222 has a guide structure at the end away from the second main body part 221 to facilitate the insertion of the second mating part 222 into the mating hole 212a. Optionally, the guide structure can be a chamfer or a rounded corner, etc.

[0101] In some embodiments, the outer diameter of the second main body portion 221 near the second mating portion 222 is larger than the outer diameter of the tube body 21. Thus, since the elastic body 30 is sleeved on the outside of the tube body 21, when the design space of the bushing 100 is small, the thickness and volume of the elastic body 30 can be increased to facilitate adjustment of parameters such as the stiffness performance of the bushing 100. In other embodiments, the outer diameter of the second main body portion 221 near the second mating portion 222 may also be equal to or smaller than the outer diameter of the inner tube 20, and this is not limited here.

[0102] In some embodiments, the diameter of the first via 211a is 0 to 0.7 mm smaller than the diameter of the second via 22a to further improve connection reliability. For example, the diameter of the first via 211a is 0.5 mm smaller than the diameter of the second via 22a.

[0103] In some embodiments, the bushing 100 further includes a middle tube 40 disposed between the inner tube 20 and the outer tube 10, and the middle tube 40 is radially spaced from both the inner tube 20 and the outer tube 10, respectively, and an elastomer 30 is wrapped around the middle tube 40. Optionally, during assembly, the elastomer 30 is used to securely bond the outer tube 10, the middle tube 40, and the tube body 21 together by injection molding vulcanization, and then the reinforcing end 22 is press-fitted to the tube body 21.

[0104] In some embodiments, the elastomer 30 extends from one end of the tube 21 to the other end of the tube 21 to increase the volume of the elastomer 30.

[0105] In some embodiments, the elastomer 30 extends from one end of the outer tube 10 to the other end of the outer tube 10 to increase the volume of the elastomer 30.

[0106] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
