[0032] Reference below Figure 1-Figure 7 The following describes a suspension assembly 10 according to an embodiment of the first aspect of the present invention, wherein the suspension assembly 10 is applied to a vehicle 100 as an example, but the invention is not limited thereto.

[0033] like Figure 1-Figure 7 As shown, the suspension assembly 10 according to the embodiment of the first aspect of the present utility model includes: a subframe 110 , two steering gears 120 and two control arms 130 .

[0034] Specifically, two steering gears 120 are provided on the subframe 110, a first end of each control arm 130 is connected to the steering gear 120, and a second end of each control arm 130 is adapted to be connected to the brake 20. The two control arms 130 are arranged in an inverted figure eight shape.

[0035] For example, in Figure 1-Figure 7 In the example, when the suspension assembly 10 is applied to the vehicle 100, the suspension assembly 10 is arranged at the rear wheel of the vehicle 100, and the brake 20 is connected to the rear wheel, and the brake 20 is located on the outside of the suspension assembly 10. The subframe 110 is arranged under the vehicle body, and the two steering gears 120 are located on the side of the brake 20 away from the front wheel of the vehicle 100. The two steering gears 120 control the two rear wheels respectively. For example, the steering gear 120 can control the pull rod through the internal motor to control the left and right deflection of the brake 20 and the rear wheel. Different angles of deflection of the two rear wheels can be achieved simultaneously, so that the entire vehicle can implement more steering strategies. Optionally, the maximum deflection angle of the rear wheel controlled by the steering gear 120 exceeds 12 degrees.

[0036] The two control arms 130 are arranged on the side of the subframe 110 away from the vehicle body. The two control arms 130 are both located on the outside of the subframe 110, and the first end of each control arm 130 is connected to one of the brakes 20 through a rubber sleeve, and the second end of each control arm 130 is connected to the subframe 110.

[0037] Among them, the two steering gears 120 are both located behind the brake 20, and the minimum distance between the two control arms 130 gradually decreases in the direction from the brake 20 to the steering gear 120. That is, in the length direction of the vehicle 100, that is, in the X-direction, the minimum distance between the first ends of the two control arms 130 is smaller, and the minimum distance between the second ends of the two control arms 130 is larger. When the viewing angle is parallel to the X-direction and toward the front of the vehicle, when looking down at the suspension assembly 10, the two control arms 130 are designed in an inverted figure eight shape.

[0038] Because the subframe 110 is located between the two control arms 130, the rear drive assembly 30 is mounted on the subframe 110. The highly integrated, rearward-facing, and high-power rear drive assembly 30 places significant cooling demands on its motor, such as an oil-cooled motor. The heat exchanger 320 and oil pump 330 required for cooling the oil-cooled motor typically protrude from the housing 310 of the rear drive assembly 30. This is limited by the size of the motor and reducer in the Y-direction (the width of the vehicle 100), and by human comfort and vehicle ground clearance in the Z-direction (the height of the vehicle 100). Consequently, the heat exchanger 320 and oil pump 330 are typically positioned behind the motor in the X-direction. This results in an unusually congested layout space between the output of the rear drive assembly 30 and the subframe 110 in the X-direction.

[0039] Therefore, the two control arms 130 with an inverted figure-eight design increase the layout space between the two control arms 130, thereby increasing the layout space from the output end of the rear drive assembly 30 to the subframe 110, so that the highly integrated rear drive assembly 30 can have a larger layout space, thereby ensuring that the rear drive assembly 30 can have more layout methods, improving the applicability of the suspension assembly 10, and facilitating the layout of the entire vehicle.

[0040] It should be noted that the two control arms 130 with an inverted figure-eight design are more advantageous for a highly integrated rear-reversing dual-motor drive assembly, especially for a vehicle 100 with a short wheelbase but still wanting to ensure three rows of footrest space.

[0041] According to the suspension assembly 10 of the embodiment of the present invention, the minimum distance between the two control arms 130 in the direction from the brake 20 to the steering gear 120 is gradually reduced, so that the two control arms 130 are designed in an inverted eight shape, so that the highly integrated rear-wheel drive assembly 30 can have a larger layout space, thereby ensuring that the rear-wheel drive assembly 30 can have more layout methods, improving the applicability of the suspension assembly 10, and facilitating the layout of the entire vehicle.

[0042] According to some embodiments of the present invention, referring to Figure 1 、 Figure 2 and Figure 7 The sub-frame 110 includes two longitudinal beams 111 and two transverse beams. The two longitudinal beams 111 are arranged along a first direction (eg, Figure 1 The two beams are spaced apart along the second direction (eg, Figure 1 The first direction may be the width direction of the vehicle 100 (eg, the X direction in FIG. 1 ). Figure 1 The second direction may be the length direction of the vehicle 100 (eg, Figure 1 in the X direction).

[0043] like Figure 1 、 Figure 2and Figure 6 As shown, each longitudinal beam 111 extends along the length of the vehicle 100, and the two longitudinal beams 111 are generally parallel. The two cross beams are a front cross beam 112 and a rear cross beam 113. The ends of the front cross beam 112 are connected to the front ends of the two longitudinal beams 111, respectively. In the width direction of the vehicle, the length of the front cross beam 112 is slightly greater than the maximum distance between the two longitudinal beams 111, that is, the ends of the front cross beam 112 protrude from the longitudinal beams 111, facilitating the connection between the front cross beam 112 and the vehicle body. Similarly, the ends of the rear cross beam 113 are connected to the rear ends of the two longitudinal beams 111, respectively. In the width direction of the vehicle, the length of the rear cross beam 113 is slightly greater than the maximum distance between the two longitudinal beams 111, that is, the ends of the rear cross beam 113 protrude from the longitudinal beams 111, facilitating the connection between the rear cross beam 113 and the vehicle body.

[0044] At least a portion of at least one of the two cross beams protrudes in a direction away from the center of the sub-frame 110 to form a protruding portion 114, and both steering gears 120 are provided on the protruding portion 114. For example, a protruding portion is formed on one of the two cross beams (not shown); or, a protruding portion is formed on both cross beams (e.g., Figure 7 shown).

[0045] like Figure 7 As shown, the two side surfaces of each crossbeam in the second direction can be a first surface and a second surface. The first surface is adjacent to the center of the subframe 110, and a portion of the first surface protrudes toward the second surface to form a raised portion. The width of the raised portion in the second direction is smaller than the width of the remaining portion. This arrangement ensures the structural strength of the subframe 110 while increasing the area of ​​the hollow region of the subframe 110, thereby providing more space for the rear drive assembly 30.

[0046] Optionally, the rear drive assembly 30 may be fixed to the subframe 110 using four suspension brackets.

[0047] Furthermore, if Figure 1-Figure 3 As shown, the two crossbeams are the front crossbeam 112 and the rear crossbeam 113, and the two steering gears 120 are both located near the middle of the rear crossbeam 113. In the third direction, the two steering gears 120 are both located below the rear crossbeam 113. The third direction, the second direction, and the first direction are orthogonal to each other. It should be noted that the third direction can be the height direction of the vehicle 100 (for example, Figure 3 in the Z direction).

[0048] With this arrangement, the two steering gears 120 are arranged in a figure-eight shape and are symmetrical about the central axis of the subframe 110. This allows the center of gravity of the suspension assembly 10 to be located at its central axis, ensuring level and stability during vehicle travel. Furthermore, the space below the subframe 110 is effectively utilized, making the suspension assembly 10 compact.

[0049] According to some specific embodiments of the present invention, Figure 1 and Figure 4 The subframe 110 further includes two connecting plates 115, each connected to either side of the rear cross member 113 in the third direction. Each steering gear 120 includes a first connecting post 121 and a second connecting post 122. The first connecting post 121 is connected to the rear cross member 113, and the second connecting post 122 passes through one of the connecting plates 115, connecting the rear cross member 113 to the other connecting plate 115.

[0050] The two connecting plates 115 may be a first connecting plate and a second connecting plate. The first connecting plate is fixed to the upper surface of the rear cross beam 113, and the second connecting plate is fixed to the lower surface of the rear cross beam 113. Each connecting plate 115 is formed with two first mounting holes, and the rear cross beam 113 is formed with two second mounting locations. The first connecting post 121 of each steering gear 120 is connected to one of the second mounting locations, and the second connecting post 122 of each steering gear 120 passes through one of the first mounting holes and is connected to the other first mounting hole of the rear cross beam 113 to secure the steering gear 120 to the rear cross beam 113.

[0051] In this way, the steering gear 120 can be arranged in the Z direction, so that the Z-direction cross-section area of ​​the rear cross beam 113 is smaller. There is no need to set a structure extending downward on the rear cross beam 113 for mounting the steering gear 120. While ensuring the structural strength of the subframe 110, the cost can be reduced, and the space below the rear cross beam 113 can be vacated, which is conducive to the arrangement of other components.

[0052] Furthermore, each connecting plate 115 includes a first sub-plate 115a and a second sub-plate 115b connected to each other, the first sub-plate 115a is connected to the rear cross beam 113, and the second sub-plate 115b is located on the side of the rear cross beam 113 away from the cross beam. Each steering gear 120 has a third connecting post, and the third connecting post is connected to the two second sub-plates 115b. Figure 4 and Figure 7 As shown, the first sub-plate 115a is generally rectangular in shape. The two first sub-plates 115a are spaced apart along the height of the vehicle to define a clamping slot, within which the protrusion of the rear cross member 113 is clamped. The second sub-plate 115b is generally triangular in shape and is located behind the rear cross member 113. The two second sub-plates 115b are welded together to form two third mounting holes. The third mounting holes provide a third fixing point for each steering gear 120. Specifically, the third connecting column fits within the third mounting holes, further securely securing the steering gear 120 to the rear cross member 113.

[0053] According to some embodiments of the present invention, each longitudinal beam 111 includes a first beam segment and a second beam segment connected to each other, wherein in the third direction, the first beam segment is located on a side of the second beam segment adjacent to the diverter 120. The first beam segment is a solid structure, and the second beam segment is a hollow structure.

[0054] Since the rear axle load of the three-motor model is relatively large, the weight of the whole vehicle is also increasing with the increase of vehicle power and functions, resulting in greater force on the air spring 190 and a larger diameter. At the same time, the highly integrated rear dual electric drive requires a large Y-direction space for the arrangement of the motor and reducer.

[0055] By making the upper half of the longitudinal beam 111 (i.e., the first beam section) a solid structure and the lower half of the longitudinal beam 111 (i.e., the second beam section) a hollow structure, the Y-direction cross-sectional area of ​​the longitudinal beam 111 can be made smaller, which can increase the Y-direction space of the subframe 110. This is conducive to the suspension assembly adapting to vehicles 100 with limited vehicle width and larger air springs 190 / coil springs, providing feasibility for highly integrated rear-drive assemblies 30 and new energy vehicles 100 with larger rear axle loads, and can make the Y-direction design of the suspension assembly 10 more compact.

[0056] According to some embodiments of the present invention, Figure 1 As shown, the suspension assembly 10 further includes two first connecting arms 140 and a lateral stabilizer bar 150. The two first connecting arms 140 are respectively disposed on either side of the subframe 110 in the first direction, with the two ends of each first connecting arm 140 respectively connected to the subframe 110 and the brake 20. The lateral stabilizer bar 150 is disposed on a side of the rear cross member 113 away from the front cross member 112. In the third direction, the lateral stabilizer bar 150 is located between the connecting plate 115 and the steering gear 120, and the two ends of the lateral stabilizer bar 150 are connected to the two first connecting arms 140.

[0057] For example, in Figure 1 and Figure 2 In the example, two first connecting arms 140 are located on the left and right sides of the subframe 110, respectively. Each first connecting arm 140 is located between the brake 20 and the subframe 110 and above the control arm 130. The ends of each first connecting arm 140 are connected to the subframe 110 and the brake 20, respectively, via rubber sleeves. A stabilizer bar 150 is connected to the two first connecting arms 140 via stabilizer rod balls at each end. The stabilizer bar 150 is positioned above the steering gear 120 and fixed to the rear of the subframe 110. Two connecting plates 115 on the rear cross member 113 wrap around and protect the stabilizer bar 150. Thus, the stabilizer bar 150 and the steering gear 120 are arranged in the Z direction, which saves space in the X direction for the suspension assembly and makes the suspension assembly more compact, which is more advantageous for vehicles 100 with limited rear overhang length.

[0058] In other optional embodiments, the steering gear 120 may be arranged above the rear cross beam 113 , and the transverse stabilizer bar 150 may be fixed to the side of the rear cross beam 113 , which can further increase the structural strength of the rear cross beam 113 .

[0059] Furthermore, if Figure 1-Figure 2 As shown, the suspension assembly 10 further includes two guide arms 160, two trailing arms 170, and two second connecting arms 18015. The two guide arms 160 are respectively disposed on either side of the front cross member 112 in the first direction, with each guide arm 160 having two ends connected to the front cross member 112 and the brake 20. The two trailing arms 170 are respectively disposed on either side of the subframe 110 in the first direction, with each trailing arm 170 located between the guide arm 160 and the first connecting arm 140, and each trailing arm 170 having two ends connected to the longitudinal beam 111 and the brake 20. The two second connecting arms 180 are respectively disposed on either side of the subframe 110 in the first direction, with each second connecting arm 180 located between the trailing arm 170 and the first connecting arm 140, and each second connecting arm 180 having two ends connected to the longitudinal beam 111 and the brake 20.

[0060] Reference Figure 1 and Figure 2 The trailing arm 170, guide arm 160, second connecting arm 180, control arm 130, and anti-roll bar 150, located on the same side of the subframe 110, are arranged in sequence along the direction from the brake 20 to the steering gear 120. The ends of each trailing arm 170 are connected to the brake 20 and the end of the front cross member 112 via rubber sleeves, respectively. The ends of each guide arm 160 are connected to the brake 20 and the longitudinal beam 111 via rubber sleeves, respectively. The ends of each second connecting arm 180 are connected to the brake 20 and the longitudinal beam 111 via rubber sleeves. This makes the structure of the suspension assembly 10 more compact, facilitating the layout of the suspension assembly 10 on the vehicle.

[0061] Furthermore, the suspension assembly 10 further includes: two empty springs 190 and two transmission shafts 210, the two empty springs 190 are respectively provided on the two second connecting arms 180, and each empty spring 190 is located above the steering gear 120 in the third direction, and each transmission shaft 210 is provided between the guide arm 160 and the empty spring 190, and the two ends of each transmission shaft 210 are respectively suitable for connecting to the rear drive assembly 30 and the brake 20. Figure 1 and Figure 2Each free spring 190 is positioned between the guide arm 160 and the first connecting arm 140. The two ends of each free spring 190 are connected to the second connecting arm 180 and the vehicle floor, respectively, to support the vehicle body. Each drive shaft 210 is positioned in front of the corresponding free spring 190. One end of each drive shaft 210 is connected to the output of the rear drive assembly 30, and the other end of each drive shaft 210 is connected to the corresponding brake 20. Two shock absorbers 230 are arranged outside the two free springs 190. One end of each shock absorber 230 is connected to the brake disc of the brake 20, and the other end of each shock absorber 230 is connected to the side panel of the vehicle body. Thus, the drive shaft 210, shock absorber 230, subframe 110, first connecting arm 140, and second connecting arm 180 are all arranged around the free spring 190, making the structure of the suspension assembly 10 more compact.

[0062] Among them, since the transmission shaft 210 is arranged above the longitudinal beam 111, in order to ensure the structural strength and rigidity of the longitudinal beam 111 near the transmission shaft 210, the longitudinal beam 111 is divided into a first beam section and a second beam section to form an O-shaped wrapping for the transmission shaft 210.

[0063] Optionally, the air spring 190 and the shock absorber 230 can be integrated into one body, which can further reduce the space occupied by the suspension assembly 10 and provide more possibilities for a highly integrated rear-wheel drive assembly 30.

[0064] According to some embodiments of the present invention, the suspension assembly 10 further includes: a plurality of bushings 220. In the description of the present invention, "a plurality" means two or more. The plurality of bushings 220 are respectively arranged at the corners of the subframe 110. The first end of each bushing 220 is connected to the subframe 110, and the second end of each bushing 220 is suitable for connecting to the vehicle body. For example, Figure 1-Figure 2 In the example, there are four bushings 220, two of which are located at the ends of the front cross member 112, and the remaining two bushings 220 are located at the ends of the rear cross member 113. The bushings 220 on the rear cross member 113 are positioned between the air spring 190 and the steering gear 120 in the X-direction. Because the subframe 110 has a "II"-shaped structure and the four bushings 220 are arranged at the four corners of the subframe 110, this arrangement shortens the length of the cross member protruding from the longitudinal beam 111. This reduces excess subframe 110, making it more compact and reducing its weight while also saving costs.

[0065] like Figure 1-Figure 3 As shown, a vehicle 100 according to an embodiment of the second aspect of the present invention includes: a suspension assembly 10, a brake 20 and a rear drive assembly 30. The suspension assembly 10 is the suspension assembly 10 according to the embodiment of the first aspect of the present invention.

[0066] Specifically, the brake 20 is provided on the outside of the suspension assembly 10, and the rear drive assembly 30 is provided on the subframe 110 of the suspension assembly 10. Figure 1-Figure 3 In the example, there are two brakes 20, which are respectively arranged on the left and right sides of the suspension assembly 10, and the rear drive assembly 30 is arranged in the hollow area of ​​the subframe 110, and the output end of the rear drive assembly 30 is connected to the drive shaft 210 to transmit power to the brake 20 to achieve braking of the vehicle 100.

[0067] The vehicle 100 according to the embodiment of the present invention adopts the above-mentioned suspension assembly 10, which provides multiple layout possibilities for the highly integrated rear drive assembly 30, saves space in the X and Y directions of the entire vehicle, and is more beneficial to the layout of the entire vehicle.

[0068] According to some embodiments of the present invention, referring to Figure 1-Figure 3 The rear drive assembly 30 includes a housing 310, a heat exchanger 320, and an oil pump 330. The housing 310 is located on a side of the steering gear 120 of the suspension assembly 10 adjacent to the front cross member 112. The heat exchanger 320 is located between the housing 310 and the steering gear 120 in the second direction, and is located above the steering gear 120 in the third direction. The oil pump 330 and the heat exchanger 320 are both located on the same side of the housing 310 in the second direction, and the steering gear 120 is located between the oil pump 330 and the heat exchanger 320 in the third direction.

[0069] Because the steering gear 120 is mounted on the subframe 110 along the Z-direction, the Z-direction cross-section of the rear cross member 113 of the subframe 110 is smaller, thereby providing more space for wiring, parts placement, or motor assembly and maintenance at the rear lower portion of the rear drive assembly 30. Furthermore, the heat exchanger 320 and oil pump 330 can be arranged in the space between the protruding portion 114 of the rear cross member 113 and the housing 310, with the oil pump 330 positioned below the steering gear 120. This effectively utilizes the space at the rear lower portion of the rear drive assembly 30, making the vehicle 100 more compact.

[0070] According to some embodiments of the present invention, Figure 3As shown, the rear drive assembly 30 also includes: an oil filter 340. In the third direction, the oil filter 340 is arranged between the steering gear 120 and the oil pump 330. The cooling oil of the rear drive assembly 30 requires the oil filter 340 to filter impurities. Usually, the oil filter 340 is arranged below the electric drive where there is more oil or in a dry oil sump below the electric drive. After long-term use, the filter element of the oil filter 340 needs to be replaced. When replacing, the oil filter 340 needs to be pulled out of the rear drive assembly 30. The Y-direction extraction may be blocked by the subframe 110, the five-link or the exhaust pipe. Therefore, by arranging the oil filter 340 below the steering gear 120, there are no other components arranged near the oil filter 340, which is convenient for replacing the oil filter 340 and can improve replacement efficiency.
