[0029] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0030] Reference below Figure 1-Figure 5 The suspension assembly 100 according to the embodiment of the present invention is described. The suspension assembly 100 can be applied to a vehicle.

[0031] Combination Figure 1 and Figure 2 As shown, the suspension assembly 100 according to the utility model can mainly include: a suspension crossbeam 10, a suspension rod 20 and a mounting bracket 30, wherein the suspension crossbeam 10 is used to be arranged between two longitudinal beams arranged laterally spaced apart and used to be connected to the powertrain, the suspension rod 20 is arranged on the suspension crossbeam 10, and the length of the suspension rod 20 is adjustable, and the mounting bracket 30 is arranged at one end of the suspension rod 20 laterally away from the suspension crossbeam 10 and used to be connected to the longitudinal beam.

[0032] Specifically, by arranging the suspension rod 20 on the suspension cross beam 10, and arranging the mounting bracket 30 on one end of the suspension rod 20 laterally away from the suspension cross beam 10, the suspension cross beam 10, the suspension rod 20 and the mounting bracket 30 are assembled to form the overall structure of the suspension assembly 100, and the suspension assembly 100 is designed in a segmented manner. The suspension assembly 100 can be connected between two longitudinal beams arranged laterally at intervals, and can be connected to the powertrain.

[0033] In a specific embodiment of the present invention, there are two suspension rods 20 and two mounting brackets 30. The two suspension rods 20 are respectively arranged at the two lateral ends of the suspension beam 10, and the two mounting brackets 30 are respectively arranged at one end of the two suspension rods 20 that is laterally away from the suspension beam 10, thereby forming the overall structure of the suspension assembly 100. The two mounting brackets 30 can be respectively connected to the two longitudinal beams, and the suspension beam 10 can be connected to the powertrain.

[0034] In this way, on the one hand, compared with the prior art in which a crossbeam is connected to a longitudinal beam, and a suspension bracket is arranged on the crossbeam to connect to the powertrain, the suspension assembly 100 of the present application can integrate the functions of the crossbeam and the suspension bracket, reduce the number of components, and solve the adaptation problem of the crossbeam of the subframe and the suspension bracket. On the other hand, the segmented design of the suspension crossbeam 10, the suspension rod 20 and the mounting bracket 30 is also more flexible and changeable. Any one of the suspension crossbeam 10, the suspension rod 20 and the mounting bracket 30 can be replaced according to the actual application scenario, so that the suspension assembly 100 can be adapted to more different vehicle models, thereby improving the platformization rate of the suspension assembly 100 and reducing the development and reliability verification costs.

[0035] Furthermore, the length of the suspension rod 20 is made adjustable, so that the overall lateral length of the suspension assembly 100 can be adjusted by adjusting the length of the suspension rod 20, thereby further making the suspension assembly 100 adaptable to more different vehicle models, improving the platformization rate of the suspension assembly 100, and reducing development and reliability verification costs.

[0036] Therefore, by setting the suspension rod 20 on the suspension beam 10, and setting the mounting bracket 30 at one end of the suspension rod 20 laterally away from the suspension beam 10, wherein the suspension beam 10 is used to be connected to the powertrain, the mounting bracket 30 is used to be connected to the longitudinal beam, and the length of the suspension rod 20 is adjustable, the suspension assembly 100 can be adapted to more different vehicle models, the platform rate of the suspension assembly 100 can be improved, and the development and reliability verification costs can be reduced.

[0037] Combination Figure 1-Figure 5 As shown, a first suspension bushing 11 is arranged on the suspension beam 10, and the first suspension bushing 11 is used to be connected to the powertrain. A second suspension bushing 21 is arranged between one end of the suspension rod 20 and the suspension beam 10, and a third suspension bushing 31 is arranged between the other end of the suspension rod 20 and the mounting bracket 30.

[0038] Specifically, by arranging the first suspension bushing 11 on the suspension crossbeam 10, the first suspension bushing 11 can be used to connect with the powertrain, and the first suspension bushing 11 can play a role of vibration isolation. By arranging the second suspension bushing 21 between one end of the suspension tie rod 20 and the suspension crossbeam 10, the second suspension bushing 21 can play a role of vibration isolation. By arranging the third suspension bushing 31 between the other end of the suspension tie rod 20 and the mounting bracket 30, the third suspension bushing 31 can play a role of vibration isolation.

[0039] In this way, by setting the first suspension bushing 11, the second suspension bushing 21 and the third suspension bushing 31, a three-stage vibration isolation system can be formed in the suspension assembly 100. Compared with the single-stage or double-stage vibration isolation system in the prior art, the ratio of the dynamic and static stiffness of the suspension assembly 100 is greatly reduced, which can effectively improve the vibration isolation effect and play a good role in isolating vibration in a wider frequency range. In addition, this can also effectively suppress the strong impact and load force of the powertrain or the ground during vehicle acceleration, deceleration, braking or abuse conditions, improve the problem of reduced vibration isolation performance due to large torque direction stiffness and rapid stiffness increase, and improve the driving experience of the whole vehicle.

[0040] It should be noted that the structures and sizes of the first suspension bushing 11, the second suspension bushing 21 and the third suspension bushing 31 are of equal or unequal structural design, and the dynamic and static stiffness of the first suspension bushing 11, the second suspension bushing 21 and the third suspension bushing 31 can also be adjusted to adapt to the application of different vehicle models, which will not be elaborated here.

[0042] Specifically, by providing a second through hole 22 at one end of the suspension rod 20, the second suspension bushing 21 can be installed in the second through hole 22, and the second suspension bushing 21 and the second through hole 22 are interference fit, so that the second suspension bushing 21 can be arranged on the suspension rod 20, which is not only simple and convenient, but also stable and reliable. And by providing a first through hole 12 on the suspension beam 10, when assembling the suspension assembly 100, it is only necessary to make the first through hole 12 correspond to the second suspension bushing 21, and then make the first fastener penetrate the first through hole 12 and the second suspension bushing 21 at the same time, so that the detachable connection between the suspension beam 10 and the suspension rod 20 can be achieved, and the second suspension bushing 21 can isolate the transmission of vibration between the suspension beam 10 and the suspension rod 20, thereby ensuring the vibration isolation effect of the suspension assembly 100.

[0043] Optionally, a first mounting hole 16 can be set at one end of the suspension beam 10, at least part of the suspension rod 20 and the second suspension bushing 21 are set in the first mounting hole 16, and the second through hole 22 is located in the first mounting hole 16, and the second through hole 22 corresponds to the second suspension bushing 21.

[0044] Combination Figure 1-Figure 5As shown, a third through hole 23 is provided at the other end of the suspension rod 20, a fourth through hole 32 is provided on the mounting bracket 30, a third suspension bushing 31 is installed in the fourth through hole 32 and is interference fit with the fourth through hole 32, and the third through hole 23 and the third suspension bushing 31 correspond to each other and are detachably connected by a second fastener.

[0045] Specifically, by setting the fourth through hole 32 on the mounting bracket 30, the third suspension bushing 31 can be installed in the fourth through hole 32, and the third suspension bushing 31 and the fourth through hole 32 are interference fit, so that the third suspension bushing 31 can be set on the mounting bracket 30, which is not only simple and convenient, but also stable and reliable. And by setting the third through hole 23 at the other end of the suspension rod 20, when assembling the suspension assembly 100, it is only necessary to make the third through hole 23 correspond to the third suspension bushing 31, and then make the second fastener penetrate the third through hole 23 and the third suspension bushing 31 at the same time, so as to realize the detachable connection between the suspension rod 20 and the mounting bracket 30, and make the third suspension bushing 31 isolate the transmission of vibration between the suspension rod 20 and the mounting bracket 30, thereby ensuring the vibration isolation effect of the suspension assembly 100.

[0046] Optionally, a second mounting hole 26 can be set at the other end of the suspension rod 20, and the fourth through hole 32 of the mounting bracket 30 and the third suspension bushing 31 extend into the second mounting hole 26. The third through hole 23 is located on the side wall of the second mounting hole 26. There are two third through holes 23, and the two third through holes 23 correspond to the third suspension bushing 31.

[0047] Combination Figure 2 and Figure 4 As shown, the suspension rod 20 can mainly include a first rod 24 and a second rod 25, one end of the first rod 24 is connected to the suspension beam 10, one end of the second rod 25 is connected to the mounting bracket 30, and the other end of the first rod 24 is movably connected to the other end of the second rod 25 so that the length of the suspension rod 20 is adjustable.

[0048] Specifically, one end of the first tie rod 24 is connected to the suspension beam 10, and one end of the second tie rod 25 is connected to the mounting bracket 30. By movably connecting the other end of the first tie rod 24 with the other end of the second tie rod 25, the length of the suspension tie rod 20 can be adjusted, thereby adjusting the overall lateral length of the suspension assembly 100, thereby making the suspension assembly 100 adaptable to more different vehicle models, improving the platformization rate of the suspension assembly 100, and reducing development and reliability verification costs.

[0049] Combination Figure 2 and Figure 4As shown, the second pull rod 25 is at least partially sleeved on the outer periphery of the first pull rod 24, the first pull rod 24 is provided with a plurality of elastic protrusions 2421, the second pull rod 25 is provided with a plurality of fixing holes 251, and at least part of the plurality of elastic protrusions 2421 is selectively elastically connected with at least part of the plurality of fixing holes 251.

[0050] Specifically, at least part of the multiple elastic protrusions 2421 on the first pull rod 24 can be locked with at least part of the multiple fixing holes 251 on the second pull rod 25, thereby ensuring the structural reliability of the suspension rod 20, and the second pull rod 25 can be moved relative to the first pull rod 24 by applying force to the suspension rod 20. The elastic protrusions 2421 are selectively squeezed in the process and then selectively locked with the fixing holes 251 again.

[0051] That is, the number of locking fits between the elastic protrusion 2421 and the fixing hole 251 can be changed to achieve telescopic fit between the first pull rod 24 and the second pull rod 25, thereby adjusting the length of the suspension pull rod 20 and making the adjustment of the length of the suspension pull rod 20 simpler and more reliable.

[0052] Combination Figure 2 and Figure 4 As shown, the first pull rod 24 may include a pull rod body 241 and an arc-shaped spring piece 242. The pull rod body 241 is provided with an avoidance hole 2411. The arc-shaped spring piece 242 is arranged in the pull rod body 241. An elastic protrusion 2421 is arranged on the arc-shaped spring piece 242. The elastic protrusion 2421 extends from the avoidance hole 2411 and is selectively elastically fixed to the fixing hole 251.

[0053] Specifically, an avoidance hole 2411 is opened on the pull rod body 241, and an arc-shaped spring piece 242 is arranged in the pull rod body 241 and corresponds to the avoidance hole 2411. The arc-shaped spring piece 242 has elasticity, so that when the elastic protrusion 2421 is not compressed, the arc-shaped spring piece 242 restores the elastic deformation, and the elastic protrusion 2421 extends out through the avoidance hole 2411. When the elastic protrusion 2421 is compressed, the arc-shaped spring piece 242 can be elastically deformed, and the elastic protrusion 2421 is retracted into the pull rod body 241 through the avoidance hole 2411, thereby making the structure of the first pull rod 24 simpler and more reliable, and making the movable connection between the first pull rod 24 and the second pull rod 25 simpler and more reliable. The arc spring piece 242 may be made of manganese steel, and may be a semicircular manganese steel sheet. The arc spring piece 242 may be locked with the second pull rod 25 by utilizing its super elasticity and the principle of not deforming under repeated strong pressure, thereby ensuring the structural reliability of the suspension pull rod 20.

[0054] Combination Figure 3As shown, the suspension beam 10 can mainly include a main body 13 and a mounting portion 14, the main body 13 is connected to the suspension rod 20, the mounting portion 14 is arranged on the main body 13, a first suspension bushing 11 is arranged on the suspension beam 10, the first suspension bushing 11 is used to be connected to the powertrain, the first suspension bushing 11 is arranged on the mounting portion 14, reinforcement portions 15 are arranged between the lateral sides of the mounting portion 14 and the main body 13, and the reinforcement portion 15, the mounting portion 14 and the main body 13 are together arranged to form a triangle.

[0055] Specifically, the main body 13 is extended in the transverse direction, and the main body 13 can be used to be connected to the suspension rod 20. By setting the mounting portion 14 on the main body 13, a through hole is formed in the mounting portion 14, and the first suspension bushing 11 can be press-fitted into the through hole in the mounting portion 14 by interference fit, thereby realizing the installation of the first suspension bushing 11 on the suspension beam 10, which is not only simple and convenient, but also stable and reliable.

[0056] Furthermore, considering that the powertrain is connected to the first suspension bushing 11, the structure near the mounting portion 14 is subjected to greater stress. By arranging reinforcement portions 15 between the mounting portion 14 and the main body 13 on both lateral sides, the reinforcement portions 15, the mounting portion 14 and the main body 13 are together arranged to form a triangle. In this way, the stability principle of the triangle can be utilized to improve the structural stiffness and strength of the suspension beam 10 near the first suspension bushing 11, thereby ensuring the installation stiffness of the powertrain on the suspension assembly 100, which not only ensures the structural stability and reliability, but also improves the vibration isolation capability of the suspension assembly 100.

[0057] The suspension beam 10 can be manufactured by casting, forging, stamping or other processes according to properties such as strength and stiffness, and no specific limitation is made here.

[0058] Combination Figure 1-Figure 3 As shown, there are multiple first suspension bushings 11, and multiple first suspension bushings 11 are arranged transversely and spaced apart on the suspension crossbeam 10. Specifically, multiple mounting portions 14 can be provided, and multiple mounting portions 14 are arranged transversely and spaced apart on the main body 13. Correspondingly, multiple first suspension bushings 11 are provided, and multiple first suspension bushings 11 are arranged one by one in multiple mounting portions 14. Each first suspension bushing 11 can be used to connect with the powertrain, so that the structural design of the suspension crossbeam 10 and even the suspension assembly 100 can be further optimized to adapt to different layout positions of the powertrain.

[0059] Combination Figure 1 , Figure 2 and Figure 5 As shown, the mounting bracket 30 is provided with a fifth through hole 33 , and the fifth through hole 33 is used for connecting and fixing with the longitudinal beam. There are a plurality of fifth through holes 33 , and the plurality of fifth through holes 33 are arranged at intervals on the mounting bracket 30 .

[0060] Specifically, by providing a fifth through hole 33 on the mounting bracket 30, the third fastener can be passed through the fifth through hole 33 and connected to the longitudinal beam, thereby achieving connection and fixation between the mounting bracket 30 and the longitudinal beam, that is, the connection between the suspension assembly 100 and the longitudinal beam can be achieved, making the connection and fixation between the suspension assembly 100 and the longitudinal beam simpler and more reliable.

[0061] Furthermore, the fifth through-hole 33 can be set to be multiple, and the multiple fifth through-holes 33 are spaced apart on the mounting bracket 30. Specifically, some of the multiple fifth through-holes 33 are spaced apart in the longitudinal direction, and another part of the multiple fifth through-holes 33 are spaced apart in the up-down direction. This can not only further improve the connection stability between the suspension assembly 100 and the longitudinal beam, but also adjust the longitudinal installation position of the suspension assembly 100 by adjusting the longitudinal spacing distance between the multiple fifth through-holes 33, or adjust the up-down installation position of the suspension assembly 100 by adjusting the up-down spacing distance between the multiple fifth through-holes 33. This can facilitate the adjustment of the longitudinal and up-down positions of the powertrain, so that the suspension assembly 100 can be adapted to different vehicle models, reduce development and reliability verification costs, and improve the platformization rate of the suspension assembly 100.

[0062] The vehicle according to the utility model may mainly include: the above-mentioned suspension assembly 100. Specifically, by applying the suspension assembly 100 to the vehicle, the suspension assembly 100 and the longitudinal beam form a subframe, and the powertrain is connected to the suspension assembly 100, not only can the segmented design of the suspension assembly 100 solve the adaptation problem of various front / rear welded crossbeams and suspensions of the subframe, reduce product types, reduce development and reliability verification costs, improve platformization rate, and have strong adaptability and compatibility, but also can improve the vibration isolation capability, improve the NVH performance of the whole vehicle and the driving experience, thereby improving the product competitiveness of the vehicle and the user experience.
