Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to a suspension system and vehicle. Background Technology

[0002] In existing technology, a suspension system is typically installed between the vehicle body and the wheels. The main function of the suspension system is to ensure proper contact between the wheels and the ground and to absorb impacts and vibrations from uneven road surfaces. The suspension system includes springs and shock absorbers. Springs bear the vertical load from the wheels and provide elastic support. The main function of shock absorbers is to absorb impacts and vibrations from uneven road surfaces to improve vehicle comfort and handling. Especially in off-road or rough road conditions, shock absorbers mitigate the relative movement between the wheels and the vehicle body, ensuring vehicle stability and passenger comfort.

[0003] However, in certain extreme driving conditions, such as challenging off-road driving, mountain climbing, and traversing sandy or muddy terrain, wheel lift-off is quite common. When the wheel is completely off the ground, the shock absorber's effectiveness is greatly affected, causing it to fail to perform its intended function, and the vehicle's traction drops significantly. At this point, the wheel no longer generates sufficient friction with the ground, and the vehicle loses its normal driving ability. Especially during off-road driving, after the wheel has been off the ground for a period of time, the vehicle may not be able to regain sufficient ground contact, making it unable to pass obstacles or climb hills, and there is also the possibility of spring dislodgement.

[0030] The following is for reference. Figures 1-5 Description of a suspension system 100 according to an embodiment of the present utility model.

[0031] like Figure 1 As shown, a suspension system 100 according to an embodiment of the present invention includes: a fixed seat 10, a spring member 20, a support member 30, and an elastic pad 40.

[0032] The mounting base 10 is used to connect one of the vehicle body and the wheel assembly, and the spring member 20 is used to connect the other of the vehicle body and the wheel assembly. The support member 30 is located between the mounting base 10 and the spring member 20, and the support member 30 is connected to the end of the spring member 20 near the mounting base 10. The elastic pad 40 is located between the support member 30 and the mounting base 10.

[0033] The fixed seat 10 and the spring member 20 are disposed between the vehicle body and the wheel assembly. When the vehicle travels on an uneven road surface, the spring member 20 undergoes elastic deformation, causing the wheel assembly to fall to the ground.

[0034] In existing technology, a suspension system is typically installed between the vehicle body and the wheels. The main function of the suspension system is to ensure proper contact between the wheels and the ground and to absorb impacts and vibrations from uneven road surfaces. The suspension system includes springs and shock absorbers. Springs bear the vertical load from the wheels and provide elastic support. The main function of shock absorbers is to absorb impacts and vibrations from uneven road surfaces to improve vehicle comfort and handling. Especially in off-road or rough road conditions, shock absorbers mitigate the relative movement between the wheels and the vehicle body, ensuring vehicle stability and passenger comfort.

[0035] However, in certain extreme driving conditions, such as challenging off-road driving, mountain climbing, and traversing sandy or muddy terrain, wheel lift-off is quite common. When the wheel is completely off the ground, the shock absorber's effectiveness is greatly affected, causing it to fail to perform its intended function, and the vehicle's traction drops significantly. At this point, the wheel no longer generates sufficient friction with the ground, and the vehicle loses its normal driving ability. Especially during off-road driving, after the wheel has been off the ground for a period of time, the vehicle may not be able to regain sufficient ground contact, making it unable to pass obstacles or climb hills, and there is also the possibility of spring dislodgement.

[0036] In this embodiment of the invention, the elastic pad 40 can also undergo elastic deformation through the cooperation of the fixed seat 10, the support member 30 and the elastic pad 40. In extreme driving environments, compared with the distance between the vehicle body and the wheel assembly in related technologies, the distance between the vehicle body and the wheel assembly in this embodiment of the invention is larger, so that the wheel assembly is always in contact with the ground, thus improving passability.

[0037] Meanwhile, it should be noted that in related technologies, under extreme driving conditions, the wheel assembly bounces, and the shock absorber device experiences a lower limit impact, resulting in abnormal noise and impact sensation. In this embodiment of the present invention, through the cooperation of the fixed seat 10, the support member 30 and the elastic pad 40, even if the vehicle encounters the same driving environment, the lower limit impact will not occur, thereby improving the situation of abnormal noise and impact sensation and improving comfort.

[0038] Specifically, when the fixed seat 10 is connected to the vehicle body, the spring member 20 is connected to the wheel assembly; or, when the fixed seat 10 is connected to the wheel assembly, the spring member 20 is connected to the vehicle body.

[0039] According to the embodiment of the present utility model, the suspension system 100, through the cooperation of the fixed seat 10, the support member 30 and the elastic pad 40, increases the distance between the vehicle body and the wheel assembly in extreme driving environments, so that the wheel assembly is always in contact with the ground, reducing the probability of the spring member 20 coming off, improving passability, and improving the situation of abnormal noise and impact feeling, thus improving comfort.

[0040] like Figure 1 , Figure 5 As shown, in some embodiments, the fixed base 10 is provided with a first guide structure 11, and the support member 30 is provided with a first mating part 31. The first guide structure 11 and the first mating part 31 cooperate to guide the support member 30 to move.

[0041] The first guide structure 11 cooperates with the first mating part 31, and the support member 30 moves according to a predetermined trajectory.

[0042] In the above scheme, the cooperation between the first guide structure 11 and the first mating part 31 enables the support member 30 to move stably and avoids the support member 30 from shaking, thereby improving the stability of the structural movement and the reliability of the suspension system 100.

[0043] In some specific embodiments, one of the first guiding structure 11 and the first mating part 31 is a columnar structure and the other is a structural hole. The columnar structure is inserted into the structural hole, so that the support member 30 can move stably.

[0044] In some embodiments, the first guide structure 11 is configured as a hollow tube, and the first mating part 31 is configured as a mating post, which is inserted into the hollow tube.

[0045] The mating column is inserted into the hollow tube, and the inner wall of the hollow tube contacts the outer wall of the mating column, causing the hollow tube to move along the extension direction of the mating column.

[0046] In the above scheme, the hollow tube moves along the extension direction of the mating column through the cooperation of the hollow tube and the mating column, making the movement of the support 30 more stable, thereby improving reliability and avoiding the shaking of the support 30.

[0047] like Figure 1 As shown, in some embodiments, the elastic pad 40 is provided with a second mating part 41, which engages with the first guiding structure 11 to guide the movement of the elastic pad 40.

[0048] The elastic pad 40 is provided with a second mating part 41. Under the guidance of the first guide structure 11, the elastic pad 40 moves along the extension direction of the first guide structure 11 to avoid the elastic pad 40 from shaking.

[0049] In the above solution, by providing a second mating part 41 on the elastic pad 40, and the second mating part 41 cooperating with the first guide structure 11, the elastic pad 40 can move stably, avoiding the elastic pad 40 from shaking, and improving the reliability of the suspension system 100.

[0050] Specifically, the first guide structure 11 is constructed as a mating post, and the second mating part 41 is constructed as a structural hole. The mating post is inserted into the structural hole to stabilize the elastic pad 40.

[0051] like Figure 1 As shown, in some embodiments, the fixing base 10 is provided with a fixing plate 12, which is located on the side of the fixing base 10 facing the support member 30. The fixing plate 12 is provided with a clearance hole 121. The elastic pad 40 has a first end near the fixing base 10 and a second end near the support member 30. The size of the first end is larger than the size of the clearance hole 121, and the size of the second end is smaller than the size of the clearance hole 121.

[0052] The clearance hole 121 on the fixing plate 12 avoids the elastic pad 40, which extends from one side of the fixing plate 12 to the other side to abut against the support member 30. The two ends of the elastic pad 40 are a first end and a second end, respectively. The first end is close to the fixing seat 10, and the second end is close to the support member 30. The size of the second end is smaller than the size of the clearance hole 121, so that the second end passes through the clearance hole 121 and abuts against the support member 30.

[0053] In the above scheme, by setting a first end and a second end, the size of the first end is larger than the size of the clearance hole 121, and the size of the second end is smaller than the size of the clearance hole 121, the fixing plate 12 restricts the elastic pad 40, preventing the elastic pad 40 from falling off, and at the same time making the elastic pad 40 and the support member 30 abut well.

[0054] Specifically, the elastic pad 40 is shaped like a frustum, which is inverted within the clearance hole 121, and the clearance hole 121 is used to position the frustum. The size of the first end is the diameter of one end of the frustum, and the size of the second end is the diameter of the other end of the frustum.

[0055] like Figure 1 As shown, in some embodiments, the support member 30 is provided with a second guide structure 32, and the fixing plate 12 is provided with a third mating part 122. The second guide structure 32 and the third mating part 122 cooperate to guide the movement of the support member 30.

[0056] The second guide structure 32 on the support member 30 cooperates with the third mating part 122 on the fixed plate 12 to guide the movement of the support member 30 and prevent the support member 30 from shaking.

[0057] In the above scheme, the support member 30 is stabilized by the cooperation of the second guide structure 32 and the third mating part 122. The overall structure is simple and practical, avoids the shaking of the support member 30, and improves the overall reliability.

[0058] like Figure 1 As shown, in some embodiments, there are multiple second guide structures 32, and the multiple second guide structures 32 are disposed on different sides of the first guide structure 11.

[0059] Among them, multiple second guide structures 32 play a role, multiple second guide structures 32 cooperate with multiple third mating parts 122 respectively, and multiple position guide support members 30.

[0060] In the above scheme, by setting multiple second guide structures 32 to guide the movement of the support member 30, and the multiple second guide structures 32 are respectively set on different sides of the first guide structure 11, the support member 30 is subjected to the support force of multiple parts, which further makes the support member 30 move stably.

[0061] For example, there are two second guide structures 32, which are respectively set on the left and right sides of the first guide structure 11, thus improving stability.

[0062] In some embodiments, the second guide structure 32 is configured as a guide post, and the third mating part 122 is configured as a mating hole, with the guide post inserted into the mating hole; wherein, a limiting part 321 is provided at one end of the guide post near the fixing seat 10, and the limiting part 321 is adapted to stop the fixing plate 12.

[0063] The guide post is inserted into the mating hole, and the guide post mates with the mating hole to guide the movement of the support member 30. A limiting part 321 is provided at one end of the guide post, and the limiting part 321 abuts against the fixed plate 12 to restrict the movement of the support member 30 and prevent the support member 30 from moving beyond its range, thus realizing auxiliary assembly during line assembly.

[0064] like Figure 1 As shown, in the above scheme, by setting a limiting part 321 at one end of the guide post, the size of the limiting part 321 is larger than the size of the mating hole. During the downward movement, the limiting part 321 abuts against the fixed plate 12, and the limiting part 321 restricts the movement of the support member 30, preventing the support member 30 from falling off, so that the support member 30 is always stable on the fixed plate 12, thereby improving the overall reliability.

[0065] like Figure 1 As shown, in some embodiments, the fixing base 10 and the fixing plate 12 together define a receiving space 13, and the first guide structure 11 is disposed within the receiving space 13.

[0066] The fixed base 10 and the fixed plate 12 together define the receiving space 13. The first guide structure 11 located in the receiving space 13 guides the first mating part 31. That is, the first guide structure 11 does not extend to the other side of the fixed plate 12 away from the receiving space 13, so as to avoid interference with the support member 30.

[0067] In some embodiments, the vehicle body is connected to a frame, and the mounting bracket 10 is connected to the frame by welding. In other embodiments, the mounting bracket 10 is directly connected to the vehicle body by welding.

[0068] In some specific embodiments, the suspension system 100 operates as follows:

[0069] In the initial state: due to the preload of spring 20, spring 20 will exert a large reaction force on the vehicle body (approximately 4000N). At this time, if... Figure 1 As shown, the spring force causes the support 30 and the fixed plate 12 to press together (a rubber buffer can be used in the middle); at this time, the elastic pad 40 is in a compressed state (compressed by about 1 / 2).

[0070] During the descent to the limit: During the descent, the preload of the spring 20 continues to decrease. When it decreases to near the limit position, the elastic pad 40 is subjected to less force due to the disappearance of the preload of the spring 20, and begins to return to its initial state. It releases the downward pressure and moves the support 30 downward, causing it to detach from the fixed plate 12, thereby preventing the spring 20 from coming off.

[0071] The aforementioned structure allows the vehicle to operate completely independently during smooth and stable driving conditions (by tightly adhering to the fixed plate 12 under preload), thus ensuring that the vehicle's performance is identical to that of the base model. Firstly, updated / replaced vehicles can utilize the previous tuning scheme (vehicles of the same quality / type). Secondly, compared to variable stiffness springs, the spring element 20 in this embodiment exhibits more linear stiffness characteristics, resulting in a more driver-friendly driving experience. Furthermore, the three limiting mechanisms simultaneously maintain a certain level of rigidity within the vehicle's smooth and stable driving range, increasing vehicle durability.

[0072] The aforementioned mechanism is a purely physical structure with no hydraulic or electrical components, resulting in better reliability, maintainability, and cost-effectiveness.

[0073] The vehicle according to an embodiment of the present invention includes the suspension system 100 described above.

[0074] According to the vehicle of this utility model embodiment, through the cooperation of the fixed seat 10, the support member 30 and the elastic pad 40, the distance between the vehicle body and the wheel assembly is increased in extreme driving environments, so that the wheel assembly is always in contact with the ground, reducing the probability of the spring member 20 coming off, improving passability, and improving the situation of abnormal noise and impact feeling, thus improving comfort.

[0075] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
