Description

Technical Field

[0001] The present invention relates to the field of vehicles, in particular to an all-terrain vehicle. Background Art

[0002] In an all-terrain vehicle, considering off-road performance and passability, its suspension system usually adopts an upper and lower longitudinal beam structure, and also includes an upper control arm and a lower control arm connected to the upper and lower longitudinal beams. There is usually a front vertical beam in front of the upper and lower longitudinal beams to increase the stability of the frame structure. On the one hand, if you want to miniaturize the all-terrain vehicle or need to increase the space in the front of the frame, you can only reduce the width of the upper and lower longitudinal beams in the front and rear directions, but this will sacrifice the structural stability of the all-terrain vehicle. On the other hand, if you want to improve the structural stability of the all-terrain vehicle, you can only extend the width of the upper and lower longitudinal beams in the front and rear directions, which will lead to insufficient space in the front of the frame or increase the overall volume of the all-terrain vehicle.

The left knuckle 310 is connected to the left wheel of the all-terrain vehicle 100, and the right knuckle 320 is connected to the right wheel of the all-terrain vehicle 100.

[0029] The upper control arm is located above the lower control arm. One end of the upper control arm is connected to the upper longitudinal beam 220. One end of the lower control arm is connected to the lower longitudinal beam 230.

[0030] The upper control arm includes a left upper control arm and a right upper control arm, and the lower control arm includes a left lower control arm and a right lower control arm. That is, one end of each of the left upper control arm and the right upper control arm is connected to the upper longitudinal beam 220. One end of each of the left lower control arm and the right lower control arm is connected to the lower longitudinal beam 230.

[0031] The other end of the left upper control arm and the other end of the left lower control arm are connected to the left steering knuckle 310. The other end of the right upper control arm and the other end of the right lower control arm are connected to the right steering knuckle 320.

[0032] Further, the left upper control arm includes a first front control sub-arm 411 and a first rear control sub-arm 412.

[0033] It can be understood that the first front control sub-arm 411 is located in front of the first rear control sub-arm 412, and the connection point between the first rear control sub-arm 412 and the upper longitudinal beam 220 is located at the rear side of the connection point between the first front control sub-arm 411 and the upper longitudinal beam 220. The second front control sub-arm 421 is located in front of the second rear control sub-arm 422, and the connection point between the second rear control sub-arm 422 and the upper longitudinal beam 220 is located at the rear side of the connection point between the second front control sub-arm 421 and the upper longitudinal beam 220. The third front control sub-arm 431 is located in front of the third rear control sub-arm 432, and the connection point between the third rear control sub-arm 432 and the lower longitudinal beam 230 is located at the rear side of the connection point between the third front control sub-arm 431 and the lower longitudinal beam 230. The fourth front control sub-arm 441 is located in front of the fourth rear control sub-arm 442, and the connection point between the fourth rear control sub-arm 442 and the lower longitudinal beam 230 is located at the rear side of the connection point between the fourth front control sub-arm 441 and the lower longitudinal beam 230.

[0034] In addition, the connection point between the first front control sub-arm 411 and the upper longitudinal beam 220 and the connection point between the second front control sub-arm 421 and the upper longitudinal beam 220 are both located in front of the connection point between the front vertical beam 210 and the upper longitudinal beam 220 (the upper end of the front vertical beam 210) in the front-to-back direction. The connection point between the third front control sub-arm 431 and the lower longitudinal beam 230 and the connection point between the fourth front control sub-arm 441 and the lower longitudinal beam 230 are both located in front of the connection point between the front vertical beam 210 and the lower longitudinal beam 230 (the lower end of the front vertical beam 210) in the front-to-back direction. At the same time, a space is formed between the front side of the front vertical beam 210, the upper longitudinal beam 220 and the lower longitudinal beam 230.

[0035] The all-terrain vehicle provided according to the embodiment of the present invention increases the width of the upper control arm and the lower control arm in the front-to-back direction by arranging the connection point between the first front control sub-arm and the upper longitudinal beam and the connection point between the second front control sub-arm and the upper longitudinal beam in front of the connection point between the front vertical beam and the upper longitudinal beam, and arranging the connection point between the third front control sub-arm and the lower longitudinal beam and the connection point between the fourth front control sub-arm and the lower longitudinal beam in front of the connection point between the front vertical beam and the lower longitudinal beam, thereby increasing the structural stability of the all-terrain vehicle. In addition, since a space is formed between the front side of the front vertical beam, the upper longitudinal beam and the lower longitudinal beam, the space can be used to arrange vehicle structural parts such as a winch and a bumper, making the structure of the all-terrain vehicle compact, making full use of the space, and improving the space utilization rate of the all-terrain vehicle.

[0036] Therefore, the all-terrain vehicle provided by the embodiment of the present invention has the advantages of good structural stability and high space utilization.

[0037] exist Figure 1-Figure 5In the specific embodiment shown, the upper longitudinal beam 220 includes a left upper longitudinal beam 221 and a right upper longitudinal beam 222 that are spaced apart in the left-right direction. The left upper longitudinal beam 221 and the right upper longitudinal beam 222 are aligned in both the up-down direction and the left-right direction. The lower longitudinal beam 230 includes a left lower longitudinal beam 231 and a right lower longitudinal beam 232 that are spaced apart in the left-right direction. The left lower longitudinal beam 231 and the right lower longitudinal beam 232 are aligned in both the up-down direction and the left-right direction. Further, as Figure 3 As shown, the left upper longitudinal beam 221 , the right upper longitudinal beam 222 , the left lower longitudinal beam 231 , and the right lower longitudinal beam 232 are symmetrically arranged relative to the all-terrain vehicle 100 .

[0038] The front vertical beam 210 includes a left front vertical beam 211 and a right front vertical beam 212. The left front vertical beam 211 is connected to each of the left upper longitudinal beam 221 and the left lower longitudinal beam 231, and the right front vertical beam 212 is connected to each of the right upper longitudinal beam 222 and the right lower longitudinal beam 232. Specifically, the upper end of the left front vertical beam 211 is connected to the left upper longitudinal beam 221, the lower end of the left front vertical beam 211 is connected to the left lower longitudinal beam 231, the upper end of the right front vertical beam 212 is connected to the right upper longitudinal beam 222, and the lower end of the right front vertical beam 212 is connected to the right lower longitudinal beam 232. Further, the left front vertical beam 211 and the right front vertical beam 212 are aligned in the front-to-back direction to make the structure of the all-terrain vehicle 100 more reasonable.

[0039] One end of the left upper control arm (the first front control sub-arm 411 and the first rear control sub-arm 412) is connected to the left upper longitudinal beam 221, and one end of the right upper control arm (the second front control sub-arm 421 and the second rear control sub-arm 422) is connected to the right upper longitudinal beam 222. One end of the left lower control arm (the third front control sub-arm 431 and the third rear control sub-arm 432) is connected to the left lower longitudinal beam 231, and one end of the right lower control arm (the fourth front control sub-arm 441 and the fourth rear control sub-arm 442) is connected to the right lower longitudinal beam 232. Further, the first front control sub-arm 411 and the second front control sub-arm 421 are symmetrically arranged relative to the left upper longitudinal beam 221 and the right upper longitudinal beam 222, and the first rear control sub-arm 412 and the second rear control sub-arm 422 are symmetrically arranged relative to the left upper longitudinal beam 221 and the right upper longitudinal beam 222. The third front control sub-arm 431 and the fourth front control sub-arm 441 are symmetrically arranged relative to the left lower longitudinal beam 231 and the right lower longitudinal beam 232. The third rear control sub-arm 432 and the fourth rear control sub-arm 442 are symmetrically arranged relative to the left lower longitudinal beam 231 and the right lower longitudinal beam 232, so as to make the structure of the all-terrain vehicle 100 more reasonable.

[0040] The connection point between the first rear control sub-arm 412 and the left upper longitudinal beam 221 is located behind the connection point between the left front vertical beam 211 and the left upper longitudinal beam 221 in the front-to-rear direction, the connection point between the second rear control sub-arm 422 and the right upper longitudinal beam 222 is located behind the connection point between the right front vertical beam 212 and the right upper longitudinal beam 222 in the front-to-rear direction, the connection point between the third rear control sub-arm 432 and the left lower longitudinal beam 231 is located behind the connection point between the left front vertical beam 211 and the left lower longitudinal beam 231 in the front-to-rear direction, and the connection point between the fourth rear control sub-arm 442 and the right lower longitudinal beam 232 is located behind the connection point between the right front vertical beam 212 and the right lower longitudinal beam 232 in the front-to-rear direction.

[0041] It is understandable that the left front vertical beam 211 and the right front vertical beam 212 are arranged at intervals. Therefore, a space with a certain length in the left-right direction is formed in front of the left front vertical beam 211 and the right front vertical beam 212, in front of the left upper longitudinal beam 221 and the left lower longitudinal beam 231, and between the right upper longitudinal beam 222 and the right lower longitudinal beam 232, and the volume of the space is larger, which can further improve the space utilization rate.

[0042] like Figure 1-Figure 3 As shown, the left upper longitudinal beam 221 and the right upper longitudinal beam 222 are connected by a plurality of cross beams 500, and the left lower longitudinal beam 231 and the right lower longitudinal beam 232 are connected by a plurality of cross beams 500, which improves the structural stability and bearing capacity of the frame. It is understandable that in order to improve the structural stability of the frame, a plurality of connecting rods 600 for connecting and supporting can be provided between the upper longitudinal beam 220 and the lower longitudinal beam 230.

[0043] Furthermore, if Figure 1 As shown, the connection point between the first front control sub-arm 411 and the left upper longitudinal beam 221 is aligned with the connection point between the second front control sub-arm 421 and the right upper longitudinal beam 222 in the front-to-back direction, the connection point between the third front control sub-arm 431 and the left lower longitudinal beam 231 is aligned with the connection point between the fourth front control sub-arm 441 and the right lower longitudinal beam 232 in the front-to-back direction, the connection point between the first rear control sub-arm 412 and the left upper longitudinal beam 221 is aligned with the connection point between the second rear control sub-arm 422 and the right upper longitudinal beam 222 in the front-to-back direction, and the connection point between the third rear control sub-arm 432 and the left lower longitudinal beam 231 is aligned with the connection point between the fourth rear control sub-arm 442 and the right lower longitudinal beam 232 in the front-to-back direction, so as to make the structure of the all-terrain vehicle 100 more reasonable.

[0044] Furthermore, if Figure 1 and Figure 2 As shown, the length of the upper longitudinal beam 220 is shorter than that of the lower longitudinal beam 230. The front ends of the upper longitudinal beams 220 (the left upper longitudinal beam 221 and the right upper longitudinal beam 222) are located in front of the front ends of the lower longitudinal beams 230 (the left lower longitudinal beam 231 and the right lower longitudinal beam 232), and the rear ends of the upper longitudinal beams 220 are located in front of the rear ends of the lower longitudinal beams 230.

The connection point between the third front control sub-arm 431 and the left lower longitudinal beam 231 is located at the rear side of the connection point between the first front control sub-arm 411 and the left upper longitudinal beam 221. It can also be said that the connection point between the fourth front control sub-arm 441 and the right lower longitudinal beam 232 is located at the rear side of the connection point between the second front control sub-arm 421 and the right upper longitudinal beam 222, so as to improve the passability of the all-terrain vehicle 100.

[0046] The connection point between the first rear control sub-arm 412 and the left upper longitudinal beam 221 is located in front of the connection point between the third rear control sub-arm 432 and the left lower longitudinal beam 231. It can also be said that the connection point between the second rear control sub-arm 422 and the right upper longitudinal beam 222 is located in front of the connection point between the fourth rear control sub-arm 442 and the right lower longitudinal beam 232, which facilitates the installation of components (such as the steering gear assembly 900) at the rear of the frame, making the structure of the all-terrain vehicle 100 more reasonable.

[0047] Furthermore, if Figure 3 As shown, the distance between the connection point between the first front control sub-arm 411 and the left upper longitudinal beam 221 and the connection point between the second front control sub-arm 421 and the right upper longitudinal beam 222 in the left-right direction is A, and the distance between the connection point between the third front control sub-arm 431 and the left lower longitudinal beam 231 and the connection point between the fourth front control sub-arm 441 and the right lower longitudinal beam 232 in the left-right direction is B, and A is greater than B. In addition, the projection of the left upper longitudinal beam 221 in the up-down direction is located on the left side of the projection of the left lower longitudinal beam 231 in the up-down direction, and the projection of the right upper longitudinal beam 222 in the up-down direction is located on the right side of the projection of the right lower longitudinal beam 232 in the up-down direction. The upper end of the left upper longitudinal beam 221 is located on the left side of its lower end, and the upper end of the right upper longitudinal beam 222 is located on the right side of its lower end. The left upper longitudinal beam 221 and the right upper longitudinal beam 222 are both arranged obliquely. The above arrangements all improve the structural stability and structural rationality of the all-terrain vehicle 100.

[0048] like Figure 3As shown, the left steering knuckle 310 is located at a lower position on the left side of the vehicle frame, the right steering knuckle 320 is located at a lower position on the right side of the vehicle frame, and the upper control arm and the lower control arm are both inclined downward from the connection point with the vehicle frame, that is, the connection points of the upper control arm with the left steering knuckle 310 and the right steering knuckle 320 are both located below the connection points with the vehicle frame, and the connection points of the lower control arm with the left steering knuckle 310 and the right steering knuckle 320 are also located below the connection points with the vehicle frame. Specifically, the left upper control arm and the left lower control arm both extend downward to the left from the connection point with the vehicle frame to connect with the left steering knuckle 310, and the right upper control arm and the right lower control arm both extend downward to the right from the connection point with the vehicle frame to connect with the right steering knuckle 320.

One end of each of the left shock absorber 710 and the right shock absorber 720 is connected to the vehicle frame. The other end of the left shock absorber 710 is connected to the left upper control arm. The left shock absorber 710 extends downward to the left from the connection point with the vehicle frame and is connected to the left upper control arm, that is, the other end of the left shock absorber 710 is located at the lower left of the one end. The other end of the right shock absorber 720 is connected to the right upper control arm. The right shock absorber 720 extends downward to the right from the connection point with the vehicle frame and is connected to the right upper control arm, that is, the other end of the right shock absorber is located at the lower right of the one end.

[0050] like Figure 3 As shown, the connection point between the left shock absorber 710 and the vehicle frame is located to the upper right of the connection point with the left upper control arm, and the connection point between the right shock absorber 720 and the vehicle frame is located to the upper left of the connection point with the left upper control arm. Preferably, the left shock absorber 710 and the right shock absorber 720 are symmetrically arranged. It can also be said that the upper end of the left shock absorber 710 and the upper end of the right shock absorber 720 are connected to the vehicle frame, the lower end of the left shock absorber 710 is connected to the left upper control arm, and the lower end of the right shock absorber 720 is connected to the right upper control arm.

[0051] Specifically, Figure 3As shown, the vehicle frame includes a first support rod 450 connected to the left upper longitudinal beam 221 and a second support rod 460 connected to the right upper longitudinal beam 222. The first support rod 450 extends upward from the connection with the left upper longitudinal beam 221, and the second support rod 460 extends upward from the connection with the right upper longitudinal beam 222. The vehicle frame also includes a first connecting frame 470 and a second connecting frame 480. The upper end of the first support rod 450 is connected to the first connecting frame 470, and the upper end of the second support rod 460 is connected to the second connecting frame 480. The lower end of the left shock absorber 710 is connected to the first rear control sub-arm 412, and the lower end of the right shock absorber 720 is connected to the second rear control sub-arm 422. The left shock absorber 710 extends to the right and upward from the connection with the first rear control sub-arm 412, and the upper end of the left shock absorber 710 is connected to the upper end of the first support rod 450 through the first connecting frame 470. The right shock absorber 720 extends to the left and upward from the connection with the second rear control sub-arm 422, and the upper end of the right shock absorber 720 is connected to the upper end of the second support rod 460 through the second connecting frame 480.

[0052] In addition, the connection point between the left shock absorber 710 and the first rear control sub-arm 412 (the connection point between the lower end of the left shock absorber 710 and the first rear control sub-arm 412) is located near the left steering knuckle 310, and the connection point between the right shock absorber 720 and the second rear control sub-arm 422 (the connection point between the lower end of the right shock absorber 720 and the second rear control sub-arm 422) is located near the right steering knuckle 320, that is, the lower end of the left shock absorber 710 is set as far to the left as possible, and the lower end of the right shock absorber 720 is set as far to the right as possible, so that the extension length of the left shock absorber 710 and the right shock absorber 720 is longer, so that the movement stroke of the left shock absorber 710 and the right shock absorber 720 can be longer, thereby improving the shock absorption performance and improving the comfort of the all-terrain vehicle 100.

[0053] It is understandable that in other embodiments, the left shock absorber 710 and the right shock absorber 720 may be connected in other ways, which will not be described in detail here.

[0054] like Figure 3 As shown, the all-terrain vehicle 100 further includes a left headlight 730 and a right headlight 740, and the left headlight 730 and the right headlight 740 are symmetrically arranged. The connection point between the left shock absorber 710 and the vehicle frame (the connection point between the left shock absorber 710 and the first connecting frame 470) is located behind the left headlight 730, and the connection point between the right shock absorber 720 and the vehicle frame (the connection point between the right shock absorber 720 and the second connecting frame 480) is located behind the right headlight 740. Since the upper end of the left shock absorber 710 is connected to the first connecting frame 470, and the upper end of the right shock absorber 720 is connected to the second connecting frame 480, it can also be said that the upper end of the left shock absorber 710 is located behind the left headlight 730, and the upper end of the right shock absorber 720 is located behind the right headlight 740.

[0055] In addition, the upper end of the left shock absorber 710 (the connection point between the left shock absorber 710 and the first connecting frame 470) is also located above at least a portion of the upper surface of the left headlight 730 in the vertical direction, and the upper end of the right shock absorber 720 (the connection point between the right shock absorber 720 and the second connecting frame 480) is also located above at least a portion of the upper surface of the right headlight 740 in the vertical direction. This arrangement increases the length of the left shock absorber 710 and the right shock absorber 720 to a certain extent. Therefore, the movement stroke of the left shock absorber 710 and the right shock absorber 720 can be longer, so that the shock absorption performance is better, the comfort of the all-terrain vehicle 100 is improved, and the internal space of the all-terrain vehicle 100 is reasonably used, so that the spatial layout of the all-terrain vehicle 100 is more reasonable.

[0056] Furthermore, if Figure 3 As shown, the upper surface of the left headlight 730 and the upper surface of the right headlight 740 both have a certain inclination angle. Specifically, the upper surfaces of the left headlight 730 and the right headlight 740 are both inclined surfaces that are inclined inwardly and downwardly, and are bilaterally symmetrical. Here, "inwardly" means that the left and right sides of the all-terrain vehicle 100 point to the direction of the middle of the all-terrain vehicle. It can also be said that the upper surfaces of the left headlight 730 and the right headlight 740 are both inclined surfaces that are inclined outwardly and upwardly, and are bilaterally symmetrical. Designing the upper surfaces of the left headlight 730 and the right headlight 740 as inclined surfaces that are inclined inwardly and downwardly improves the aesthetics of the all-terrain vehicle 100. Since the left shock absorber 710 and the right shock absorber 720 are both inclinedly arranged, the upper end of the left shock absorber 710 is located obliquely above the upper surface of the left headlight 730, and the upper end of the right shock absorber 720 is located obliquely above the upper surface of the right headlight 740, so that the structure of the all-terrain vehicle 100 is more reasonable.

[0057] Furthermore, if Figure 3 As shown, the first connecting frame 470 and the second connecting frame 480 each include an inclined side 471 and at least two connecting positions 472 arranged in sequence along the inclined direction of the inclined side 471, wherein the relative height of the connecting position 472 on each inclined side 471 is different, and the left shock absorber 710 and the right shock absorber 720 can be selectively connected to one of the at least two connecting positions 472 on the corresponding inclined side 471. Figure 3 In the illustrated embodiment, three connection positions 472 are provided on each inclined bevel 471, and the left shock absorber 710 is connected to the connection position 472 located in the middle on the inclined side 471 of the first connecting frame 470, and the right shock absorber 720 is connected to the connection position 472 located in the middle on the inclined side 471 of the second connecting frame 480. The left shock absorber 710 and the right shock absorber 720 are arranged in this way, and the length can be adjusted according to the shock absorption demand. For example, when the left shock absorber 710 is connected to the connection position 472 located at the bottom, its shock absorption length is the shortest, and when it is connected to the connection position 472 located at the top, its shock absorption length is the longest.

[0058] Furthermore, if Figure 1 As shown, the inclined side 471 of the first connecting frame 470 is parallel to the upper surface of the left headlight 730, and the inclined side 471 of the second connecting frame 480 is parallel to the upper surface of the right headlight 740. The projection of the left headlight 730 along the front-to-back direction at least partially overlaps with the projection of the left shock absorber 710 along the front-to-back direction, and the projection of the right headlight 740 along the front-to-back direction at least partially overlaps with the projection of the right shock absorber 720 along the front-to-back direction. The connection point of the left shock absorber 710 and the first connecting frame 470 is at the highest point of the left headlight 730, and the connection point of the right shock absorber 720 and the second connecting frame 480 is lower than the highest point of the right headlight.

[0059] The all-terrain vehicle 100 further includes a stabilizer bar 830, the middle portion of which is located between the upper longitudinal beam 220 and the lower longitudinal beam 230 in the vertical direction and can be connected to the lower longitudinal beam 230. In addition, a first end of the stabilizer bar 830 is located between the left upper control arm and the left lower control arm in the vertical direction and is connected to the left lower control arm, and a second end of the stabilizer bar 830 is located between the right upper control arm and the right lower control arm in the vertical direction and is connected to the right lower control arm.

[0060] like Figure 1 As shown, the stabilizer bar 830 is U-shaped, and the middle portion of the stabilizer bar 830 extends in the left-right direction and is connected to each of the left lower longitudinal beam 231 and the right lower longitudinal beam 232. Each of the first end of the stabilizer bar 830 and the second end of the stabilizer bar 830 is located in front of the middle portion of the stabilizer bar 830. The first end of the stabilizer bar 830 is connected to the third rear control sub-arm 432, and the second end of the stabilizer bar 830 is connected to the fourth rear control sub-arm 442.

[0061] Specifically, Figure 1-Figure 5 As shown, the all-terrain vehicle 100 further includes a mounting seat 831, a first connecting rod 832, and a second connecting rod 833. The mounting seats 831 include two, and the middle portion of the stabilizer bar 830 is connected to each of the left lower longitudinal beam 231 and the right lower longitudinal beam 232 through the two mounting seats 831. As an example, Figure 4 As shown, the mounting seat 831 is mounted on the upper surface of the right lower longitudinal beam 232 and defines a through hole for the stabilizing rod 830 to pass through with the right lower longitudinal beam 232. The stabilizing rod 830 passes through the through hole, so the stabilizing rod 830 and the right lower longitudinal beam 232 are fixed to each other. The positional relationship between the stabilizing rod 830 and the left lower longitudinal beam 231 is similar, and will not be described here.

[0062] The first end of the stabilizer bar 830 is connected to the third rear control sub-arm 432 through the first connecting rod 832, and the second end of the stabilizer bar 830 is connected to the fourth rear control sub-arm 442 through the second connecting rod 833. As an example, Figure 5As shown, the fourth rear control sub-arm 442 is connected to a second bracket 834, the lower end of the second connecting rod 833 is connected to the second bracket 834, and the upper end of the second connecting rod 833 is connected to the second end of the stabilizing bar 830. Similarly, the third rear control sub-arm 432 is connected to a first bracket (not shown in the figure), the lower end of the first connecting rod 832 is connected to the first bracket, and the upper end of the first connecting rod 832 is connected to the first end of the stabilizing bar 830.

[0063] In this way, the stabilizer bar 830 of the all-terrain vehicle 100 fully and reasonably utilizes the space between the upper longitudinal beam 220 and the lower longitudinal beam 230, and by connecting the lower longitudinal beam, the left lower control arm and the right lower control arm, the structure of the all-terrain vehicle 100 is more stable and the structural strength is enhanced, so that the all-terrain vehicle 100 can withstand stronger external loads.

[0064] like Figure 1 As shown, the all-terrain vehicle 100 further includes a differential 810, a transmission shaft 820 and a steering gear assembly 900. The differential 810 is located between the upper longitudinal beam 220 and the lower longitudinal beam 230 and is connected to the transmission shaft 820. Specifically, as shown in FIG. Figure 1 As shown, the transmission shaft 820 extends in the front-to-rear direction and is connected to the differential 810 from the rear. The middle part of the stabilizer bar 830 is located behind the differential 810, and the stabilizer bar 830 is located below the transmission shaft 820. The steering gear assembly 900 is located behind the differential 810 and above the transmission shaft 820. Such an arrangement makes the all-terrain vehicle 100 compact in structure, reasonably designed, and highly stable in structure.

[0065] Specifically, Figure 1 As shown, the stabilizer bar 830 includes a cross bar 835 located in the middle, a first longitudinal bar 836 and a second longitudinal bar 837, the cross bar 835 extends in the left-right direction, the first longitudinal bar 836 is connected to the left end of the cross bar 835, the second longitudinal bar 837 is connected to the right end of the cross bar 835, the free end of the first longitudinal bar 836 (i.e. the first end of the stabilizer bar 830) is connected to the third rear control sub-arm 432 through the first connecting rod 832, and the free end of the second longitudinal bar 837 (i.e. the second end of the stabilizer bar 830) is connected to the fourth rear control sub-arm 442 through the second connecting rod 833. The transmission shaft 820 is located above the cross bar 835 (i.e. the middle part of the stabilizer bar 830), and the perpendicular midline of the connection point between the cross bar 835 and the left lower longitudinal beam 231 and the connection point between the cross bar 835 and the right lower longitudinal beam 232 intersects with the transmission shaft 820. Furthermore, the connection point between the cross bar 835 and the left lower longitudinal beam 231 and the connection point between the cross bar 835 and the right lower longitudinal beam 232 are both located behind the connection point between the transmission shaft 820 and the differential 810 .

[0066] The steering gear assembly 900 includes a steering gear, a left steering rod 911 and a right steering rod 912. The left steering knuckle 310 is connected to the steering gear through the left steering rod 911, and the right steering knuckle 320 is connected to the steering gear through the right steering rod 912. The projection of the first longitudinal rod 836 on the horizontal plane intersects with the projection of the left steering rod 911 on the horizontal plane, and the projection of the second longitudinal rod 837 on the horizontal plane intersects with the projection of the right steering rod 912 on the horizontal plane.
