[0002] With the enhancement of people's environmental awareness and the development of electric vehicle technology, the penetration rate of new energy light trucks is getting higher and higher, and more and more customers choose to use new energy light trucks. The problem of short cruising range remains the main problem of new energy vehicle models. At present, the most effective solution is to increase the battery power and vehicle lightweighting. However, when using a large-capacity mid-mounted battery, its large volume leads to a compact layout space for the rear suspension structure.

[0003] The rear suspension structure of traditional new energy light trucks adopts a longitudinal leaf spring non-independent suspension. To ensure ride comfort and handling stability, shock absorbers and anti-roll bars are usually installed. Among them, the shock absorber is arranged in front of the axle, and to avoid interference with the brake air chamber, the anti-roll bar is arranged behind the drive axle and under the frame. The lower bracket of the stabilizer bar is arranged at a relatively low position, and the rear-mounted stabilizer bar will cause poor passing performance of the vehicle due to the installation height problem.

A first fastener and a second fastener are respectively provided at the first positioning hole and the second positioning hole.

[0014] Preferably, the first connecting portion and the second connecting portion have the same morphological structure.

[0015] Due to the adoption of the above technical solutions, the beneficial effects obtained by this application are as follows:

[0016] (1) In this solution, by arranging the main body of the stabilizer bar above the leaf spring, when the main body of the stabilizer bar is connected to the leaf spring, it is not necessary to be arranged at a very low position to avoid components such as the electric drive axle, and it can avoid the long connecting bracket between the main body of the stabilizer bar and the leaf spring or the vehicle frame due to the low position of the main body of the stabilizer bar. The height between the main body of the stabilizer bar and the leaf spring and the vehicle frame is shortened, so the connection distance between the main body of the stabilizer bar and the leaf spring and the vehicle frame is relatively close, which can shorten the lengths of the first limiting member and the second limiting member, thereby reducing the weight of the intermediate connecting member between the main body of the stabilizer bar and the leaf spring and the vehicle frame, realizing the lightweight of the rear stabilizer bar assembly, and providing more sufficient layout space for components such as the electric drive axle.

[0017] (2) By setting the positioning sleeve to realize the connection between the main body of the stabilizer bar and the vehicle frame, the short-distance connection can realize the positioning and installation of the main body of the stabilizer bar on the one hand, and on the other hand, it is beneficial to make the main body of the stabilizer bar close to the vehicle frame and the leaf spring, with a compact layout. The structure of the positioning sleeve is simple, the manufacturing and assembly difficulty is low, and the space required for the assembly of the positioning sleeve itself is small. At the same time, it can position the main body of the stabilizer bar close to the vehicle frame and the leaf spring, realizing structural lightweight and compact assembly.

[0018] (3) The top of the cover plate of the leaf spring is convex to form a connecting bracket. The connecting bracket is connected to the suspension rod and is connected to the main body of the stabilizer bar through the suspension rod to limit the main body of the stabilizer bar in the vertical direction, and cooperate with the first limiting member to realize the limiting layout of the main body of the stabilizer bar. The connecting bracket is directly formed by the cover plate, which is beneficial to strengthening the structural stability of the connecting bracket and the connection stability between the cover plate and the suspension rod bracket, and is beneficial to reducing the installation steps during assembly.

[0029] This application provides a rear stabilizer bar assembly. As Figure 1 , Figure 2 shown, the vehicle rear suspension is provided with a leaf spring 5. The rear stabilizer bar assembly includes a stabilizer bar main body 1 located above the leaf spring 5 and a hanger 2 connected to the stabilizer bar main body 1. The stabilizer bar main body 1 is connected to the vehicle frame 8 through a first limiting member, and the hanger 2 is connected to the leaf spring 5 through a second limiting member.

[0030] In this solution, by arranging the stabilizer bar main body 1 above the leaf spring 5, when the stabilizer bar main body 1 is connected to the leaf spring 5, it is not necessary to be arranged at a very low position to avoid components such as the electric drive axle 7, and it can avoid the long connecting bracket 3 between the stabilizer bar main body 1 and the leaf spring 5 or the vehicle frame 8 due to the low position of the stabilizer bar main body 1. The height between the stabilizer bar main body 1 and the leaf spring 5 and the vehicle frame 8 is shortened, so the connecting distance between the stabilizer bar main body 1 and the leaf spring 5 and the vehicle frame 8 is relatively close, which can shorten the lengths of the first limiting member and the second limiting member, thereby reducing the weight of the intermediate connecting member between the stabilizer bar main body 1 and the leaf spring 5 and the vehicle frame 8, achieving the lightweight of the rear stabilizer bar assembly, and providing more sufficient layout space for the electric drive axle 7, etc.

[0031] In one embodiment, as Figure 1 , Figure 2 shown, the first limiting member includes a positioning sleeve 4 sleeved on the outer circle of the stabilizer bar main body 1, and both ends of the positioning sleeve 4 are fixed to the vehicle frame 8.

[0032] By setting the positioning sleeve 4, the connection between the stabilizer bar main body 1 and the vehicle frame 8 is realized. The short-distance connection can, on the one hand, realize the positioning installation of the stabilizer bar main body 1, and on the other hand, is conducive to making the stabilizer bar main body 1 close to the vehicle frame 8 and the leaf spring 5, with a compact layout. Moreover, the structure of the positioning sleeve 4 is simple, the manufacturing and assembly difficulty is low, and the space required for the assembly of the positioning sleeve 4 itself is small. At the same time, the stabilizer bar main body 1 can be positioned closer to the vehicle frame 8 and the leaf spring 5, achieving structural lightweight and compact assembly.

[0033] Preferably, the positioning sleeve 4 is made of a flexible material, and the inner wall of the positioning sleeve 4 closely adheres to the outer wall of the stabilizer bar body 1.

[0034] The flexible sealing sleeve is located outside the stabilizer bar body 1. In addition to limiting the stabilizer bar body 1 by fixing the sealing sleeve to the vehicle frame 8, the stabilizer bar body 1 is protected by the flexible sealing sleeve, which is beneficial to reducing wear.

[0035] Furthermore, both ends of the positioning sleeve 4 extend away from each other to form extension segments parallel to the vehicle frame 8, and fasteners for connecting the positioning sleeve 4 to the vehicle frame 8 are provided at the extension segments.

[0036] The extension segments fix the entire positioning sleeve 4 to the vehicle frame 8. The fixing position of the fastener at the extension segment can be selected according to the actual size of the stabilizer bar body 1, so as to achieve the adaptive limiting effect on the stabilizer bar body 1.

[0037] In one embodiment, as Figure 1 shown, the leaf spring 5 is provided with a cover plate 6, and the second limiting member includes a connecting bracket 3 fixed to the cover plate 6. The hanger rod 2 is connected to the cover plate 6 through the connecting bracket 3. The cover plate 6 is outside the leaf spring 5, indirectly realizing the fixation of the hanger rod 2 on the leaf spring 5.

[0038] Furthermore, the connecting bracket 3 is integrally formed with the cover plate 6 or the hanger rod 2. This is beneficial to ensuring the connection stability between the connecting bracket 3 and the cover plate 6 or the hanger rod 2, and is also beneficial to reducing the installation difficulty.

[0039] Preferably, the top of the cover plate 6 protrudes vertically to form the connecting bracket 3. In this way, the top of the cover plate 6 of the leaf spring 5 is set to protrude outward to form the connecting bracket 3. The connecting bracket 3 is connected to the hanger rod 2, and is connected to the stabilizer bar body 1 through the hanger rod 2, realizing the limit of the stabilizer bar body 1 in the vertical direction, and cooperating with the first limiting member to realize the limit arrangement of the stabilizer bar body 1. The connecting bracket 3 is directly formed by the cover plate 6, which is beneficial to strengthening the structural stability of the connecting bracket 3 and the connection stability between the cover plate 6 and the hanger rod 2, and is also beneficial to reducing the installation steps during assembly.

[0040] In one embodiment, as Figure 1 shown, the hanger rod 2 is provided with a first connecting portion 21 connected to the stabilizer bar body 1 and a second connecting portion 22 connected to the first limiting member. The first connecting portion 21 and the stabilizer bar body 1 are oppositely provided with a first positioning hole, and the second connecting portion 22 and the first limiting member are oppositely provided with a second positioning hole. A first fastener and a second fastener are respectively provided at the first positioning hole and the second positioning hole.

[0041] Preferably, the morphological structures of the first connecting portion 21 and the second connecting portion 22 are the same.

[0042] This is beneficial to maintaining the overall structural stability of the hanger rod 2 and reducing the manufacturing difficulty of the hanger rod 2.
