DETAILED DESCRIPTION

[0030] The following detailed description is presented to aid the reader in gaining a comprehensive understanding of the methods, apparatuses, and / or systems described herein. However, various changes, modifications, and equivalents can be used, and thus particular embodiments described herein are not intended as being exhaustive of what the present disclosure can provide. For example, although processes are described with regard to particular operational flows, various changes can be made within the scope of the present disclosure. For example, the order of operations can be changed, or certain operations can be performed in parallel. In addition, for the sake of brevity and clarity, some features of the description including features known in the art can not be described.

[0031] The features described herein can be implemented in different forms and should not be construed as limited to the examples described herein. Rather, these examples are provided as illustration of some of the many possible forms in which the methods, apparatuses, and / or systems described herein can be implemented.

[0032] Throughout the specification, when an element (such as a layer, region, or substrate) is referred to as being "on" another element, "connected to" another element, "coupled to" another element, "adjacent to" another element, "on top of" another element, or "covering" another element, it can be directly on, connected to, coupled to, adjacent to, on top of, or covering the other element, or one or more other elements can be interposed therebetween. In contrast, when an element is referred to as being "directly on," "directly connected to," "directly coupled to," "directly adjacent to," "directly on top of," or "directly covering" another element, there are no other elements interposed therebetween.

[0033] As used herein, the term "and / or" includes any one of the listed items and any combination of two or more of the listed items.

[0034] Although terms such as "first," "second," and "third" can be used herein to describe various elements, components, regions, layers, or sections, these elements, components, regions, layers, or sections should not be limited by these terms. Rather, these terms are only used to distinguish one element, component, region, layer, or section from another element, component, region, layer, or section. Thus, the element, component, region, layer, or section referred to as the first element, component, region, layer, or section in the examples described herein can also be referred to as the second element, component, region, layer, or section without departing from the teachings of the examples.

[0035] For ease of description, spatial terms, such as "above", "upper", "below", and "lower" can be used herein to describe the orientation of one element relative to another element as shown in the figures. Such spatial terms are intended to encompass different orientations of the device in use or operation, in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, then a component described as above relative to another component would now be below relative to the other component. Accordingly, the term "above" encompasses both a "above" and "below" orientation depending on the spatial orientation of the device. The device can be oriented in other ways (e.g., rotated 90 degrees or at other orientations) and an appropriate reorientation of the spatial terms used herein will encompass those other orientations.

[0036] The terminology used herein is for the purpose of describing various examples only and is not intended to be limiting of the disclosure. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms "comprises", "comprising", "includes", "including" and "has", "having" as used herein, are specifically intended to be construed as open-ended terms (i.e., the terms do not allow for exclusion of any other elements, but rather allow for inclusion of some or all other elements in a list or group of elements). The term "or" as used herein is specifically intended not to be exclusive (i.e., the use of "or" in the "either A or B" sense is intended).

[0037] Variations in the shapes of the elements shown in the figures can occur because of manufacturing processes and / or tolerances. Thus, the examples described herein are not limited to the precise shapes shown in the figures, but include variations in shapes that would be apparent to one of ordinary skill in the art, given the benefit of this disclosure.

[0038] Features of the examples described herein can be combined with each other as would be apparent to one of ordinary skill in the art having the benefit of the present disclosure. Furthermore, although exemplary examples have been described in some detail, various modifications and alterations to the described examples can be made in light of the teachings of the present disclosure. Accordingly, the examples described herein are not intended to limit the scope of the disclosure but rather are intended to cover all modifications and alterations to the described examples.

[0039] According to a first aspect of the present application there is provided a stabilizer bar arrangement, such as Figure 1 and Figure 2As shown, the stabilizer bar device includes a barrel portion, a stabilizing mechanism and a rocker arm 140, the barrel portion surrounds a containing space, the stabilizing mechanism is arranged in the containing space, the stabilizing mechanism includes a motor assembly 400, a speed reducer assembly 200 and a shock absorbing mechanism 300 connected in sequence, one end of the rocker arm 140 is connected with the shock absorbing mechanism 300, the other end of the rocker arm 140 is connected with the vehicle suspension, so that the output torque of the motor assembly 400 is transmitted to the vehicle suspension via the speed reducer assembly 200, the shock absorbing mechanism 300 and the rocker arm 140 in sequence, the number of the stabilizing mechanism is two, the number of the rocker arm 140 is two, the two shock absorbing mechanisms 300 included by the two stabilizing mechanisms are connected with the two rocker arms 140 respectively, and the two stabilizing mechanisms are symmetrical about the symmetry plane F-F' perpendicular to the axial direction of the barrel portion. The stabilizer bar device of the present application is provided with two stabilizing mechanisms connected with the two rocker arms 140 respectively, so that the two motor assemblies 400 of the two stabilizing mechanisms can output different torques to the two rocker arms 140 respectively, when the two motor assemblies 400 output torques in opposite directions to the two rocker arms 140, the roll of the vehicle can be buffered, when the two motor assemblies 400 output torques in the same direction to the two rocker arms 140, the suspension of the vehicle can be lifted or lowered, which enriches the function of the stabilizer bar device, so that the vehicle can adapt to various use environments.

[0040] Further, the stabilizer bar device further includes a controller (not shown in the figure), the controller is arranged separately from the barrel portion, the number of the controller is two, the two controllers are fixed on the vehicle suspension, and the two controllers are in communication connection with the two motor assemblies included by the two stabilizing mechanisms respectively, so as to control the output torque of the two motor assemblies respectively, so as to realize the switching of the function of the stabilizer bar device. Figures 1 to 14

[0041] Specifically, when the vehicle appears a left tilting trend, the rocker arm 140 connected with the left side of the vehicle suspension exerts an upward force on the left side of the vehicle suspension, and the rocker arm 140 connected with the right side of the vehicle suspension exerts a downward force on the vehicle suspension, so as to buffer the left tilting trend of the vehicle; when the vehicle appears a right tilting trend, the rocker arm 140 connected with the left side of the vehicle suspension exerts a downward force on the left side of the vehicle suspension, and the rocker arm 140 connected with the right side of the vehicle suspension exerts an upward force on the vehicle suspension, so as to buffer the right tilting trend of the vehicle. When the vehicle travels at a high speed, both of the rocker arms 140 exert a downward force on the suspension, so that the vehicle suspension is lowered, which can ensure the stability of the vehicle in traveling. When the vehicle encounters a bumpy road section, both of the rocker arms exert an upward force on the suspension, so that the vehicle suspension is raised, which can avoid damage to the chassis of the vehicle.

[0042] As Figure 1 and Figure 2 ​As shown, the barrel portion includes two barrel members 100, which are symmetrical about the symmetry plane F-F', and the barrel member 100 on the left side, the rocker arm 140, and the stabilizing mechanism will be described below.

[0043] As shown in Figure 1 and Figure 2 , the barrel member on the left side includes a first barrel 110, a second barrel 120, and a third barrel 130 connected in sequence from right to left, and the two first barrels 110 of the two barrel members 100 are connected, as shown in Figure 3 , Figure 4 and Figure 5 , the right end of the third barrel 130 is provided with a first groove 131 recessed from the inner side wall of the third barrel 130 to the outside of the third barrel 130, and the left end of the second barrel 120 is provided with a first protrusion 121 matched with the first groove 131, and the first protrusion 121 of the second barrel 120 can be arranged in the first groove 131 of the third barrel 130. By arranging the first groove 131 and the first protrusion 121, the installation precision between the third barrel 130 and the second barrel 120 can be improved.

[0044] Further, the right end of the second barrel 120 is provided with a second groove 122, and the left end of the first barrel 110 is provided with a second protrusion 111, and the second protrusion 111 can be arranged in the second groove 122, and the installation precision between the second barrel 120 and the first barrel 110 can be improved.

[0045] As shown in Figure 2 , the reducer assembly 200 can include a first planetary reducer 210, a second planetary reducer 220, and a third planetary reducer 230 arranged in sequence from right to left, the first planetary reducer 210 is located in the first barrel 110, the second planetary reducer 220 and the third planetary reducer 230 are located in the second barrel 120, and the shock absorbing mechanism 300 is arranged in the third barrel 130. The inner wall of the left end of the first barrel 110 is provided with a first ring gear 112, and the first ring gear 112 is engaged with the first planetary reducer 210; the inner wall of the right end of the second barrel 120 is provided with a second ring gear 123, and the second ring gear 123 is engaged with both the second planetary reducer 220 and the third planetary reducer 230. Through the first ring gear 112 and the second ring gear 123, the transmission of the reducer assembly 200 can be realized.

[0046] As shown in Figure 5 , the second ring gear 123 is provided with a spline 124, and the inner side wall of the first barrel 110 is provided with a spline groove, when the first barrel 110 is connected with the second barrel 120, the spline 124 is arranged in the spline groove, which can avoid the relative rotation of the first barrel 110 and the second barrel 120.

[0047] Further, compared with the case that the barrel member 100 is an integral whole, the barrel member 100 is divided into the first barrel 110, the second barrel 120 and the third barrel 130, which can facilitate the processing of the first ring gear 112 and the second ring gear 123, and facilitate the installation of the reducer assembly 200, the stabilizing assembly and the motor assembly 400 inside the barrel member 100. At the same time, it is convenient to assemble two barrel members 100 together to form the barrel portion.

[0048] As shown in Figures 6 to 9 The damping mechanism 300 includes an input assembly 310, an output assembly 320 and an elastic assembly 330, the input assembly 310 is connected with the reducer assembly 200, the output assembly 320 is connected with the rocker arm 140, the input assembly 310 includes a plurality of input teeth 313, and the output assembly 320 includes a plurality of output teeth 322. The elastic assembly 330 is arranged between the input assembly 310 and the output assembly 320, and the elastic assembly 330 is in a pre-compressed state. When the input assembly 310 rotates, the input teeth 313 move towards the output teeth 322 on one side, thereby pressing the elastic assembly on one side of the input teeth 313. At this time, the space between the input teeth 313 and the output teeth 322 on the other side increases. Since the elastic assembly 330 is in a pre-compressed state, the elastic assembly 330 on the other side of the input teeth 313 recovers at this time, and can fill the space between the input teeth 313 and the output teeth 322 on the other side. When the input teeth 313 move towards the output teeth 322 on the other side of the input teeth, the input teeth 313 can still contact the elastic assembly to achieve the buffering effect. In this way, the damping mechanism can buffer the force in two directions.

[0049] The damping mechanism can have two forms. The first form of the damping mechanism is shown in Figure 6 and Figure 7 The input assembly 310 can include an input portion 311, a mounting column 312 and eight input teeth 313. The input portion 311 can be a planet carrier of the three-stage planetary reducer 230. The mounting column 312 is arranged in the middle of the input portion 311. The eight input teeth 313 are arranged equidistantly along the circumference of the mounting column 312.

[0050] The elastic assembly 330 includes a buffer 331 and a buffer protrusion 332. The buffer 331 is sleeved on each input tooth 313. The buffer protrusion 332 is arranged on the buffer 331 and protrudes away from the input tooth 313. The buffer 331 is provided with a support 333, so that the buffer 331 has a certain strength. The elastic assembly 330 further includes a connecting piece. Two adjacent buffers 331 among the eight buffers 331 are connected by the connecting piece.

[0051] The output assembly 320 comprises a protective shell 321 and eight output teeth 322, which are equidistantly arranged along the circumference of the inner side wall of the protective shell 321, and any two adjacent output teeth 322 among the eight output teeth 322 has a buffer space, the input tooth 313 sleeved with the buffer piece 331 is arranged in the buffer space, and at this time, the buffer protrusion 332 is in a compressed state. When the stabilizer bar device is driven, if the motor assembly 400 transmits a smaller torque to the input assembly 310 through the speed reducer assembly 200, the input assembly 310 rotates relative to the output assembly 320, the buffer protrusion 332 and the buffer piece 331 are compressed, and the output assembly 320 does not rotate. If the motor assembly 400 transmits a larger torque to the input assembly 310 through the speed reducer assembly 200, the buffer protrusion 332 and the buffer piece 331 are compressed to the extent that they cannot be further compressed, thereby causing the output assembly 320 to rotate, so as to transmit the torque generated by the motor assembly 400 to the output assembly 320. The protective shell 321 of the output assembly 320 is connected with the rocker arm 140, thereby achieving the transmission of the torque to the rocker arm 140.

[0052] Preferably, the elastic assembly 330 is made of rubber material.

[0053] The second form of the damping mechanism is shown in Figure 8 and Figure 9 The damping mechanism 300 comprises an input assembly 310, an output assembly 320, an elastic assembly 330 and a housing 430. The input assembly 310 comprises an input part 311, a mounting column 312 and an input tooth 313. The number of the input tooth 313 can be six, and the six input teeth 313 are equidistantly arranged along the circumference of the mounting column. The output assembly 320 comprises an output tooth 322, an output part and a mounting ring 323. The mounting ring 323 and the output tooth 322 are both fixed on the output part, and the mounting column 312 is arranged in the mounting ring 323. The output tooth 322 is equidistantly arranged along the circumference of the mounting ring 323, and the number of the output tooth 322 is six. Any two adjacent output teeth 322 among the six output teeth 322 has a buffer space, and the number of the buffer space is six.

[0054] As shown in Figure 8 and Figure 9 The elastic assembly 330 comprises a buffer piece 331, a buffer protrusion 332 and a connecting piece 334. The two sides of any input tooth 313 are both provided with the buffer piece 331, and the buffer piece 331 can be in a cubic shape and is attached to the side of the input tooth 313. The number of the buffer piece 331 is twelve, and the twelve buffer pieces 331 can be connected through the connecting piece 334, which is in an annular structure. The side of the buffer piece 331 opposite to the input tooth 313 is provided with the buffer protrusion 332, which protrudes relative to the buffer piece 331, and the number of the buffer protrusion 332 is five.

[0055] The input tooth 313 and the elastic assembly 330 are both arranged in the buffer space, so that both sides of the output tooth 322 are also in contact with the elastic assembly 330, at this time the buffer protrusion 332 is in a compressed state. When the stabilizer bar device is in transmission, when the input assembly 310 receives a small torque, the input assembly 310 rotates relative to the output assembly 320, the buffer protrusion 332 is compressed, and the output assembly 320 will not rotate, and the rocker arm 140 connected with the output assembly 320 will not rotate. When the input assembly 310 receives a large torque, the buffer protrusion 332 and the buffer piece 331 are both compressed, thereby rotating the output assembly 320 to transmit the torque generated by the motor assembly 400 to the output assembly 320, and the protective shell 321 of the output assembly 320 is connected with the rocker arm 140, thereby achieving the transmission of torque to the rocker arm 140.

[0056] Further, the buffer piece 331 includes two buffer surfaces, both of which are provided with buffer protrusions 332, one of which is directed towards the input tooth 313, and the other of which is directed towards the output tooth 322 adjacent thereto, and both ends of the two buffer surfaces close to the connecting piece 334 are provided with recesses 335, which are recessed from the buffer surface to the inside of the buffer piece 331. When the input structure rotates, the recesses 335 can provide space for the deformation of the buffer piece 331, avoiding the root of the buffer piece 331 being cut during the rotation of the input assembly 310 and the output assembly 320, thereby avoiding damage to the buffer piece 331.

[0057] Further, the elastic assembly 330 can be made of rubber material.

[0058] As shown in Figure 10 and Figure 11 A lubricating mechanism 500 is arranged between the output end of the primary planetary reducer 210 and the input end of the secondary planetary reducer 220, and a lubricating mechanism 500 is also arranged between the output end of the secondary planetary reducer 220 and the input end of the tertiary planetary reducer 230.

[0059] The lubricating mechanism 500 can have two forms, the first form is as shown in Figure 10As shown, the lubricating mechanism 500 includes a first lubricating part 510 and a second lubricating part 520, the first planetary reducer 210, the second planetary reducer 220 and the third planetary reducer 230 respectively include a first fixed hole, a second fixed hole and a third fixed hole, and the first fixed hole, the second fixed hole and the third fixed hole are communicated. The first lubricating part 510 and the second lubricating part 520 are both annular gaskets. Taking the lubricating mechanism 500 between the first planetary reducer 210 and the second planetary reducer 220 as an example, part of the first lubricating part 510 is arranged in the first fixed hole, and the other part of the first lubricating part 510 protrudes from the first fixed hole; part of the second lubricating part 520 is arranged in the second fixed hole, and the other part of the second lubricating part 520 protrudes from the second fixed hole, and the left end of the first lubricating part 510 is in contact with the right end of the second lubricating part 520, so that the first planetary reducer 210 and the second planetary reducer 220 are arranged at intervals. The first lubricating part 510 and the second lubricating part 520 are annular gaskets, which can reduce the contact area of the first lubricating part 510 and the second lubricating part 520, and reduce the friction between the first lubricating part 510 and the second lubricating part 520.

[0060] The setting mode of the lubricating mechanism 500 between the second planetary reducer 220 and the third planetary reducer 230 is the same as that of the lubricating mechanism 500 between the second planetary reducer 220 and the first planetary reducer 210, and details are not repeated here.

The self-aligning ball 530 is clamped between the first lubricating part 510 and the second lubricating part 520, so that the first-stage planetary reducer 210 and the second-stage planetary reducer 220 are arranged at intervals.

[0069] When the lubricating mechanism 500 is in the second form, the self-aligning ball 530 can keep the damper, the reducer assembly 200 and the motor assembly 400 operating at the center of the self-aligning ball 530. At this time, the limiting part is not required.

[0070] Further, as shown in Figure 2 and Figure 3 , the stabilizing mechanism further includes a positioning column 710 and a signal acquisition plate 720. The positioning column 710 and the signal acquisition plate 720 are arranged at the right end of the motor assembly 400.

[0071] Further, the stabilizing mechanism further includes an end cover 800 and a sealing mechanism. The end cover 800 connects the rocker arm 140 and the output assembly 320 of the damping mechanism 300. The sealing mechanism is arranged between the outer surface of the end cover 800 and the inner surface of the third cylinder 130, so as to realize the sealing between the cylinder member 100 and the rocker arm 140.

The second sealing part 920 is disposed in the gap between the stabilizing member 932 and the inner wall of the cylindrical member 100.

There is a gap between the third rubber component 953 and the second rubber component 952. When the sealing mechanism is installed, the third sealing part 930 and the fourth sealing part 940 can compress the rubber sealing part 950. The second rubber component 952 and the third rubber component 953 are compressed, which can fill the gap between the second rubber component 952 and the third rubber component 953 to ensure the sealing between the end cap 800 and the third cylinder 130.

[0074] Furthermore, the cylindrical component 100, rocker arm 140, and stabilizing mechanism located on the right side have the same structure as the cylindrical component 100, rocker arm 140, and stabilizing mechanism located on the left side, and will not be described in detail here.
