[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will further describe the specific technical solutions of this application in detail in conjunction with the accompanying drawings in the embodiments of this application. The following embodiments are used to illustrate this application but are not used to limit the scope of this application.

[0040] In the embodiments of this application, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of this application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0041] In addition, in the embodiments of this application, orientation terms such as "upper", "lower", "left", and "right" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, and they are used for relative description and clarification, and they can change accordingly with the change of the orientation of the components placed in the accompanying drawings.

[0042] In the embodiments of this application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral body; it can be directly connected or indirectly connected through an intermediate medium.

[0043] In the embodiments of this application, the terms "include", "comprise", or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device including a series of elements not only includes those elements but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article, or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article, or device including that element.

[0044] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or having more advantages than other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0045] Embodiments of the present application provide a vehicle. It should be noted that the vehicle in the present application can refer to large vehicles, small vehicles, special vehicles, etc. Exemplarily, classified by vehicle type, the vehicle in the present application can be a sedan model, an off-road model, a multi-purpose vehicle (MPV) model or other models. For a vehicle, it can include an extended-range electric vehicle. The range extender consists of an engine, a generator and a controller. The engine is not connected to the vehicle drive system by a drive shaft or other means of transmission. When the on-vehicle rechargeable energy storage system cannot meet the vehicle's cruising range requirements, the range extender provides electrical energy for the vehicle's power system to extend the cruising range. In the suspension systems of fuel vehicles and pure electric vehicles, the stabilizer bar assembly is generally arranged above the front subframe and in front of the steering gear, and consists of a stabilizer bar body, a bushing body and a mounting bracket. The mounting bracket, the stabilizer bar body and the bushing body are installed along the up-and-down direction of the whole vehicle by bolts to be fixed on the subframe. The stabilizer bar body is connected between the suspension systems on both sides of the vehicle to provide additional support force when the vehicle turns, to reduce body roll and improve vehicle handling stability.

[0046] The mounting bracket is in the shape of an "Ω" structure and is formed by bending and punching a stamping part. It is simple to manufacture and easy to mass-produce. The parts outside the left and right mounting points of the stabilizer bar body generate torsion and form a motion envelope as the suspension reciprocates up and down, which requires space; the parts inside the left and right mounting points of the stabilizer bar body need to avoid the components of each system in the front compartment, thus generating a bent shape. If the front compartment space is sufficient and there is no need to avoid, it can be designed as a straight section shape, which is convenient for processing. However, for an extended-range electric vehicle, it is necessary to arrange the engine, generator and controller components, which greatly occupies the space in the up-and-down, left-and-right and front-and-rear directions of the front compartment. Limited by requirements such as vehicle travel, ground clearance, range extender selection, and steering gear selection, it is extremely difficult to arrange the stabilizer bar assembly.

[0047] On this basis, referring to Figures 1-5 , embodiments of the present application provide a stabilizer bar assembly 30. The stabilizer bar assembly 30 is used for a vehicle. The vehicle includes a subframe 10. The subframe 10 includes a subframe main body and a first cross member 11. The subframe main body is connected to the first cross member 11. The first cross member 11 extends along the left-and-right direction of the vehicle. The first cross member 11 is connected in front of the subframe main body. Specifically, the first cross member 11 is connected to the side of the subframe main body close to the forward direction of the vehicle.

[0048] For example, the subframe 10 can be a full-frame subframe. The full-frame subframe is an integrally formed frame structure, and the full-frame subframe forms a complete frame structure at the bottom of the vehicle.

[0049] For another example, the subframe 10 can be a non-full-frame subframe, and the non-full-frame subframe adopts the form of a partial frame.

[0050] The stabilizer bar assembly 30 includes a stabilizer bar body 3 and a mounting bracket 4. The mounting bracket 4 is used to connect the stabilizer bar body 3 to the first cross beam 11. In the vertical direction of the vehicle, the stabilizer bar body 3 is located below the subframe main body. Specifically, the stabilizer bar body 3 is located on the side of the subframe main body close to the ground, and the stabilizer bar body 3 is arranged parallel to the first cross beam 11, without occupying the space above the subframe main body, providing a layout space for the arrangement of other components of the vehicle. For example, if the vehicle is an extended-range electric vehicle, it can provide a layout space for the engine, generator, and controller assembly of the range extender.

[0051] In the vertical direction of the vehicle, and the stabilizer bar body 3 is located below the subframe main body. When it is necessary to replace or repair the stabilizer bar body 3, the stabilizer bar body 3 can be disassembled from the bottom of the vehicle, which is convenient for the disassembly of the stabilizer bar body 3, improves the disassembly and assembly convenience, reduces the maintenance man-hours, and thus reduces the user's usage cost.

[0052] Optionally, the stabilizer bar body 3 can be located below the first cross beam 11. Specifically, the stabilizer bar body 3 is located on the side of the first cross beam 11 close to the ground.

[0053] Optionally, the stabilizer bar body 3 can be located on one side in the front-rear direction of the first cross beam 11. Specifically, the stabilizer bar body 3 can be located on the side of the first cross beam 11 close to the forward direction of the vehicle, or the stabilizer bar body 3 can be located on the side of the first cross beam 11 close to the reverse direction of the vehicle.

[0054] For example, the structural material of the stabilizer bar body 3 is spring steel, which can be a solid structure or a hollow structure, and is processed by hot forming and cold bending forming processes. The two ends are processed by upsetting and punching processes.

[0055] For another example, the mounting bracket 4 can be stamped from a high-strength metal steel plate.

[0056] It should be noted that the vertical direction is the vertical direction of the vehicle, and the vertical direction of the vehicle is the direction along the vertical axis of the vehicle; the direction from the ground to the top of the vehicle is the upward direction, and the direction from the top of the vehicle to the ground is the downward direction. The left-right direction is the left-right direction of the vehicle, and the left-right direction of the vehicle is the direction along the transverse axis of the vehicle; the direction from the driver's side of the vehicle (usually the left side, and the right side in some countries and regions) to the co-driver's side is the rightward direction, and the direction from the co-driver's side of the vehicle (usually the right side, and the left side in some countries and regions) to the driver is the rightward direction. The front-rear direction is the front-rear direction of the vehicle, and the front-rear direction of the vehicle is the direction along the longitudinal axis of the vehicle. The direction from the front to the rear is the backward direction, that is, the forward direction of the vehicle; the direction from the rear to the front is the forward direction, that is, the reverse direction of the vehicle.

[0057] According to the stabilizer bar assembly 30 of the embodiments of the present application, the mounting bracket 4 is used to connect the stabilizer bar body 3 and the subframe 10, and the stabilizer bar body 3 is located below the subframe main body, which not only facilitates the layout of the stabilizer bar assembly 30, but also releases the space above the subframe 10, facilitating the layout of other vehicle components; and when it is necessary to replace or repair the stabilizer bar assembly 30, the stabilizer bar assembly 30 can be disassembled from the bottom of the vehicle, improving the disassembly and assembly convenience, reducing the repair man-hours, and thus reducing the user's usage cost.

[0058] Referring to Figures 1-4 , in some embodiments of the present application, the vehicle further includes a steering gear 20. The subframe main body includes a plurality of longitudinal beams 13 and a second cross beam 12. The first cross beam 11 is located in front of the second cross beam 12 and is spaced apart in the front-rear direction. The first cross beam 11 can be located at the very front end of the vehicle head, and the second cross beam 12 is located between the two front wheels of the vehicle. The plurality of longitudinal beams 13 are spaced apart in the left-right direction, and the plurality of longitudinal beams 13 are connected between the first cross beam 11 and the second cross beam 12. For example, there are two longitudinal beams 13, and the two longitudinal beams 13 are spaced apart in the left-right direction of the vehicle.

[0059] The first cross beam 11 is located below the plurality of longitudinal beams 13, and the first cross beam 11 is located on the side of the plurality of longitudinal beams 13 close to the ground. The stabilizer bar body 3 is located on the side of the first cross beam 11 close to the second cross beam 12, that is, the stabilizer bar body 3 is located behind the first cross beam 11. There is a layout space below the plurality of longitudinal beams 13. By arranging the stabilizer bar body 3 behind the first cross beam 11 and below the plurality of longitudinal beams 13, it is avoided that the stabilizer bar body 3 occupies the up-down space of the vehicle, resulting in an increase in the up-down dimension of the vehicle.

[0060] Referring to Figures 1-3 , the two longitudinal beams 13 extend in the front-rear direction of the vehicle, and the longitudinal beam 13 includes a first part and a second part. The second part is connected to the rear end of the first part, that is, the second part is located on the side of the first part close to the vehicle's reverse direction. The first part extends horizontally in the front-rear direction of the vehicle, and the first cross beam 11 is located below the first parts of the two longitudinal beams 13; the second part extends obliquely in the front-rear direction of the vehicle, and the second cross beam 12 is connected to the rear ends of the second parts of the two longitudinal beams 13. The first cross beam 11 and the second cross beam 12 can be located in the same plane of the vehicle, or the first cross beam 11 can also be located below the second cross beam 12. There is a layout space below the two longitudinal beams 13, which facilitates arranging the stabilizer bar body 3 below the two longitudinal beams 13.

[0061] The first crossbeam 11, a longitudinal beam 13, the second crossbeam 12 and another longitudinal beam 13 are connected end to end to enclose a frame structure, so as to form an accommodation space between the first crossbeam 11, the second crossbeam 12 and the two longitudinal beams 13, which can be used to accommodate other components of the vehicle. For example, the range extender of a range-extended electric vehicle includes an engine, a generator and a controller assembly.

[0062] The steering gear 20 is installed above the second crossbeam 12. Specifically, the steering gear 20 is connected to the second crossbeam 12 and is located on the side of the second crossbeam 12 close to the top of the vehicle. The steering gear 20 is located behind the stabilizer bar body 3, and enough space is reserved between the stabilizer bar body 3 and the steering gear 20 to be used for arranging other components of the vehicle. For example, the range extender of a range-extended electric vehicle includes an engine, a generator and a controller assembly.

[0063] Refer to Figures 5-9 , in some embodiments of the present application, the mounting bracket 4 includes an arc-shaped groove 41, a first plate body 42 and a second plate body 43. The first plate body 42 and the second plate body 43 are respectively connected to both ends of the arc-shaped groove 41. The stabilizer bar body 3 is located in the arc-shaped groove 41. The first plate body 42 and the second plate body 43 are respectively located on the upper and lower sides of the first crossbeam 11. The mounting bracket 4 is designed as a U-shaped bracket. The first plate body 42 and the second plate body 43 of the U-shaped bracket can cover the upper and lower surfaces of the first crossbeam 11. The first plate body 42 and the second plate body 43 can increase the contact area between the mounting bracket 4 and the first crossbeam 11, and further increase the mounting strength between the mounting bracket 4 and the first crossbeam 11.

[0064] Refer to Figure 1 , Figure 4 , the mounting bracket 4 connects the stabilizer bar body 3 to the rear of the first crossbeam 11. The stabilizer bar body 3 is located in the arc-shaped groove 41, that is, the arc-shaped groove 41 of the mounting bracket 4 is located on the side of the first crossbeam 11 close to the reverse direction of the vehicle. The first plate body 42 and the second plate body 43 are respectively connected to the side of the arc-shaped groove 41 close to the forward direction of the vehicle and extend towards the direction of the first crossbeam 11. The first plate body 42 and the second plate body 43 are respectively located on the upper and lower surfaces of the first crossbeam 11.

[0065] In a specific example, the first plate body 42 and the second plate body 43 are in clearance fit with the first crossbeam 11 in the up and down directions to improve the assembly convenience, and the clearance amount is 0.25 mm - 0.9 mm.

[0066] According to the arrangement position and size of the first crossbeam 11, the mounting bracket 4 can be designed into a symmetric or asymmetric shape to match different first crossbeams 11.

[0067] Refer to Figures 5-9, in some embodiments of the present application, the stabilizer bar assembly 30 further includes: a first fastener 61; the first plate body 42 has a second fastener 421, the second plate body 43 has a first connection hole 431, the first cross beam 11 has a through hole communicating with the first connection hole 431, and the first fastener 61 sequentially passes through the first connection hole 431 and the through hole to be connected to the second fastener 421. The first fastener 61 is installed from bottom to top, which can improve the convenience and detachable property of the assembly of the stabilizer bar body 3.

[0068] There are two mounting brackets 4. Each mounting bracket 4 has two first connection holes 431. Correspondingly, the number of the first fasteners 61 is four. When disassembling, assembling and maintaining, the four bolts connecting the stabilizer bar assembly 30 and the subframe 10 and the two nuts at both ends of the stabilizer bar body 3 can be loosened, and the stabilizer bar assembly 30 can be directly taken out from the lower side. It is not necessary to disassemble the entire suspension system and power system like fuel vehicles and pure electric vehicles to repair or replace the stabilizer bar body 3, which greatly improves the convenience of disassembly and assembly, reduces the maintenance working hours, and reduces the user's usage cost.

[0069] For example, the first fastener 61 can be a bolt, and the second fastener 421 can be a welded nut welded on the first plate body 42. Through the cooperation of the bolt and the nut, the way of fixing the stabilizer bar body 3 by the mounting bracket 4 can be simple.

[0070] In a specific example, the first connection hole 431 is a counterbore hole, and the counterbore hole is recessed in the direction towards the first cross beam 11 to avoid problems such as uneven interface force and loosening abnormal sound caused by poor flatness control of the entire large plane of the second plate body 43 of the mounting bracket 4; or, if the flatness control ability is good, the mounting surface of the mounting bracket 4 and the first cross beam 11 can be set as a large plane.

[0071] Refer to Figures 1-4 , in some embodiments of the present application, there are two mounting brackets 4. The two mounting brackets 4 are respectively located at both ends of the first cross beam 11 in the left - right direction. The two mounting brackets 4 are spaced apart on the stabilizer bar body 3 and are used to further increase the connection strength between the stabilizer bar body 3 and the first cross beam 11.

[0072] Wherein, the stabilizer bar body 3 between the two mounting brackets 4 is a straight bar extending in the left - right direction, and the extending direction of the stabilizer bar body 3 between the two mounting brackets 4 is the same as the extending direction of the first cross beam 11. The middle section of the stabilizer bar body 3 is set to be straight. During the reciprocating movement of the suspension system, it does not deform and does not occupy extra space, and can avoid interference with other components arranged between the subframe 10 and the steering gear 20.

[0073] The mounting bracket 4 includes an arc-shaped groove 41, a first plate body 42 and a second plate body 43. The stabilizer bar body 3 is located within the arc-shaped groove 41. The first plate body 42 and the second plate body 43 are respectively located on the upper and lower surfaces of the first cross beam 11. The stabilizer bar body 3 between the two mounting brackets 4 is located on one side of the first cross beam 11 close to the vehicle reverse direction.

[0074] The stabilizer bar body 3 between the two mounting brackets 4 is a straight bar extending in the left-right direction, which is the first straight bar. A first rod body and a second rod body are respectively connected to the left and right ends of the first straight bar. The first rod body and the second rod body both extend obliquely backward and extend to the left and right ends of the subframe body. Mounting points are provided at the ends of the first rod body and the second rod body facing away from the first straight bar, and are all used to be connected to the tie rod of the vehicle.

[0075] Refer to Figure 5 、 Figures 7-8 In a specific example, the two mounting brackets 4 are divided into a left mounting bracket and a right mounting bracket. The left mounting bracket has a first positioning connection hole 441 and a first positioning groove 442. The first positioning groove 442 is located at the edge of the left mounting bracket facing the first cross beam 11, and the first positioning connection hole 441 is a circular hole; the right mounting bracket has a second positioning connection hole 451 and a second positioning groove 452. The second positioning groove 452 is located at the edge of the right mounting bracket facing the first cross beam 11, and the first positioning connection hole 441 is an oval hole.

[0076] When installing the stabilizer bar body 3, the first positioning groove 442 and the second positioning groove 452 are used to position the mounting hole of the mounting bracket 4 and the first cross beam 11; the first positioning connection hole 441 and the second positioning connection hole 451 are both connected to the assembly hole of the first cross beam 11.

[0077] When the assembly requirements for the stabilizer bar body 3 are not high, or the first positioning connection hole 441 and the second positioning connection hole 451 are designed as large through holes or waist-shaped grooves, the mounting brackets 4 can also be not divided into left and right parts.

[0078] Refer to Figures 5-6 、 Figures 10-12 In some embodiments of the present application, the stabilizer bar assembly 30 further includes: a bushing body 51 and a bushing base 52. The bushing base 52 is located on the side of the bushing body 51 close to the first cross beam 11. The bushing base 52 can be fixed between the bushing body 51 and the first cross beam 11 through the extrusion action between the bushing body 51 and the first cross beam 11. The bushing base 52 provides an installation position for the bushing body 51, and the bushing base 52 plays a role in protecting the bushing body 51. For example, the bushing base 52 is located between the first plate body 42 and the second plate body 43. The two end faces of the bushing base 52 in the up-down direction are flat surfaces, which are convenient for being arranged between the first plate body 42 and the second plate body 43.

[0079] The stabilizer bar body 3 is inserted through the bushing body 51 and is in interference fit with the bushing body 51. The bushing body 51 is press-fitted and fixed to the stabilizer bar body 3 with special glue, and then bonded into one body through a thermal induction heating process to improve the connection strength between the bushing body 51 and the stabilizer bar body 3.

[0080] When the vehicle is running, the bushing body 51 can effectively absorb and buffer the vibrations and impacts generated by the stabilizer bar body 3 during operation, thereby reducing the direct transmission of vibrations to the vehicle body and improving the riding comfort. Moreover, during various movements of the vehicle's suspension system, the bushing body 51 can allow the stabilizer bar body 3 to have a certain rotation and displacement space, enabling the suspension system to operate more freely while maintaining the effectiveness of the stabilizer bar body 3.

[0081] For example, the interference amounts of the bushing body 51 and the stabilizer bar body 3 in the front-rear direction and the up-down direction of the vehicle are both greater than or equal to 0.75 mm. During the reciprocating movement of the vehicle, the bushing body 51 and the stabilizer bar body 3 always maintain an interference state to prevent the bushing body 51 from separating from the stabilizer bar body 3 during large-stroke torsion to generate gaps, resulting in abnormal noises when encountering splashing rainwater.

[0082] The bushing body 51 is composed of rubber and a skeleton. The selection of rubber needs to be adaptively designed according to requirements such as vehicle performance, heat damage requirements, and target market environment. The skeleton is generally made of metal or plastic according to the vehicle handling stability, comfort performance, and reliability requirements. The skeleton is placed inside the bushing and is produced into the bushing body 51 with the bushing through a vulcanization process. The bushing base 52 is processed from a metal material, and a casting process can be used to improve production efficiency.

[0083] Refer to Figure 5 、 Figures 10-13 In some embodiments of the present application, the bushing base 52 has a first limiting block 521, the first limiting block 521 faces the bushing body 51, the bushing body 51 has a first limiting groove 511, and the first limiting groove 511 is used to accommodate the first limiting block 521. Both the first limiting block 521 and the first limiting groove 511 extend in the up-down direction.

[0084] Among them, the first limiting block 521 is provided with a first limiting structure 5211, and a second limiting structure 5111 is provided in the first limiting groove 511. The first limiting structure 5211 cooperates with the second limiting structure 5111 to limit the position of the bushing body 51 and the bushing base 52 in the left-right direction when they are fitted together.

[0085] The first limiting block 521 and the first limiting groove 511 cooperate to increase the mating surface between the bushing body 51 and the bushing base 52, and the first limiting structure 5211 cooperates with the second limiting structure 5111 to limit the positions of the bushing body 51 and the bushing base 52. When the vehicle is running, it ensures that there is no relative movement between the bushing body 51 and the bushing base 52 during the full-stroke torsional movement, which may cause frictional abnormal noise, and avoids the problem of slippage between the stabilizer bar body 3 and the bushing body 51 and the bushing base 52.

[0086] For example, the first limiting structure 5211 can be a T-shaped block or a wedge-shaped block provided on the bushing base 52, and the second limiting structure 5111 can be a T-shaped groove or a wedge-shaped groove provided on the bushing body 51. The T-shaped block is located in the T-shaped groove, and the wedge-shaped block is located in the wedge-shaped groove.

[0087] For example, the bushing base 52 and the bushing body 51 are in an interference fit in the front-rear direction, and the interference amount is greater than or equal to 2 mm.

[0088] In a specific example, the bushing base 52 has a plurality of first limiting blocks 521, and the plurality of first limiting blocks 521 are arranged at intervals in the left-right direction. A second limiting groove 523 is formed between two adjacent first limiting blocks 521; the bushing base 52 has a plurality of first limiting grooves 511, and the plurality of first limiting grooves 511 are arranged at intervals in the left-right direction. The side wall between two adjacent first limiting grooves 511 is a second limiting block 512, and the second limiting blocks 512 are respectively located in the second limiting grooves 523.

[0089] Refer to Figures 10-13 , in some embodiments of the present application, the first limiting structure 5211 includes a first groove 5212 and a second groove 5213 provided on the first limiting block 521, and the second limiting structure 5111 includes a first protrusion 5112 and a second protrusion 5113 provided in the first limiting groove 511. The first protrusion 5112 and the second protrusion 5113 are respectively located on two opposite side walls of the first limiting groove 511. The first protrusion 5112 and the second protrusion 5113 cooperate with the first groove 5212 and the second groove 5213 respectively. The bushing body 51 can be assembled to the bushing base 52 from the up-down direction, so that the first protrusion 5112 is located in the first groove 5212 and the second protrusion 5113 is located in the second groove 5213. The first protrusion 5112 and the second protrusion 5113 can prevent the first limiting block 521 from disengaging from the first limiting groove 511 in the front-rear direction or the left-right direction, and are used to further increase the connection strength between the bushing base 52 and the bushing body 51.

[0090] Refer to Figures 1-5 , Figures 10-11, in some embodiments of the present application, the stabilizer bar assembly 30 further includes: a third fastener 62; the bushing base 52 has a through hole 522 extending in the up and down direction, the mounting bracket 4 has a mounting hole communicating with the through hole 522, and the third fastener 62 passes through the mounting hole and the through hole 522 for fixing the bushing base 52 to the mounting bracket 4.

[0091] For example, the mounting bracket 4 includes a first plate body 42 and a second plate body 43. The first plate body 42 and the second plate body 43 are respectively located on the upper and lower sides of the first cross beam 11. The mounting holes include a first mounting hole 422 and a second mounting hole 432. The first plate body 42 has the first mounting hole 422, and the second plate body 43 has the second mounting hole 432. The third fastener 62 can be a bolt. The stabilizer bar assembly 30 further includes: a fourth fastener 63. The fourth fastener 63 is a nut or a welded nut welded to the second plate body 43. The bolt can sequentially pass through the second mounting hole 432, the through hole 522, and the first mounting hole 422 and be connected to the nut or the welded nut to fixedly connect the bushing base 52 and the mounting bracket 4.

[0092] For example, the bolt can be a 10.9 grade high-strength hexagon flange face lock bolt, and the specifications can be selected as M8, M10, etc., and the selection is based on strength and reliability requirements; the nut can be a 10 grade high-strength hexagon flange face nut, and the specifications are matched with the lock bolt and selected as M8, M10, etc., and the selection is based on strength and reliability requirements. It can be selected from existing conventional standard parts to reduce the development cost.

[0093] In a specific example, a small clearance fit is set between the through hole 522 of the bushing base 52, the mounting hole of the mounting bracket 4 and the third fastener 62, and the position design of the through hole 522 and the mounting hole needs to ensure the interference amount of the bushing body 51 in the front and rear direction of the vehicle, and the interference amount is greater than or equal to 2 mm. In the up and down direction, a small clearance fit is provided between the first plate body 42, the second plate body 43 and the bushing base 52 to improve the convenience of production and assembly. The distance between the first plate body 42 and the second plate body 43 is affected by the deformation amounts of the press-fitted bushing body 51 and the mounting bracket 4, and the dimensional tolerance of the mounting bracket 4 needs to be determined according to the actual verification of the production supplier.

[0094] The production process of the stabilizer bar assembly 30 is as follows:

[0095] The first step is to form, heat-treat and paint the stabilizer bar body 3;

[0096] The second step is to place the bushing body 51 in a supporting tooling and integrate it with the stabilizer bar body 3 by medium frequency induction heating and secondary vulcanization;

[0097] The third step is to press-fit the mounting bracket 4 onto the bushing body 51;

[0098] Step 4: Press-fit the bushing base 52 and the bushing body 51 until the through hole 522 of the bushing base 52 is concentric with the mounting hole of the mounting bracket 4;

[0099] Step 5: Pass the third fastener 62 through the mounting hole of the mounting bracket 4 and the through hole 522 of the bushing base, and install the fourth fastener 63 on the third fastener 62;

[0100] Step 6: Use a torque wrench or an electric torque gun to apply torque to tighten the third fastener 62 and draw a marking line;

[0101] Step 7: Mark the product, and after passing the inspection, package it and store it in the warehouse.
