Technical Field

[0001] The present application relates to the technical field of vehicle steering systems, and in particular to a vibration absorbing device, a steering system and a vehicle. Background Art

[0002] Vehicles are used more and more widely in life and production. With the development of technology, people have higher and higher requirements for the stability and comfort of driving vehicles.

[0003] The vehicle's steering system is the component through which the driver most directly perceives the vehicle's stability and comfort. However, since the steering system's cantilever structure easily amplifies engine vibration, how to improve the stability of the steering system has become one of the research topics in the industry. Utility Model Content

[0004] In order to solve the above technical problems, the present application provides a vibration absorption device, a steering system and a vehicle. The vibration absorption device can be applied to the steering system, so as to absorb the vibration of the steering system, improve the stability of the steering system, and thereby improve the stability and comfort of people when driving the vehicle.

[0005] This application is implemented through the following technical solutions.

[0006] The first aspect of the present application provides a vibration absorbing device, which includes: a shell having a accommodating space; a mass block located in the accommodating space; an elastic member located in the accommodating space; a bracket partially passing through the shell and connected to the mass block via the elastic member, the mass block can move relative to the bracket, and the bracket is used to connect to the steering column.

[0007] Because the mass can move relative to the bracket, it absorbs vibrations from the bracket. Since the bracket is connected to the steering column, the mass absorbs vibrations from the steering column. This vibration-absorbing device can be applied to steering systems, thereby absorbing steering system vibrations and improving steering stability, thereby enhancing vehicle stability and comfort. Furthermore, because the vibration-absorbing device includes a housing within which the mass and elastic member are located, interference between the mass and surrounding structures is avoided, extending the service life of the mass and elastic member. Furthermore, this structure is simple to set up and can be applied to different vehicle models.

[0008] In some embodiments, the bracket has a cylindrical wall extending along a first direction, and the outer peripheral surface of the cylindrical wall is provided with a protrusion protruding radially outward. Along the first direction, the elastic member is connected between the protrusion and the mass block, and the elastic member can at least be elastically deformed along the first direction.

[0009] The bracket has a cylindrical wall, so the steering column can pass through the cylindrical wall, and the cylindrical wall and the steering column are connected. The elastic member is connected between the protruding portion and the mass, so the elastic connection between the bracket and the mass can be easily achieved, and the mass can at least absorb the vibration of the bracket and / or the steering column in the first direction, and the structure is simple.

[0010] In some embodiments, the mass has a groove; the protruding portion includes a first protruding portion; the elastic member includes at least one first elastic member; in the first direction, one end of the first elastic member is connected to the first protruding portion, and the other end of the first elastic member is connected to the surface of the groove opposite to the first protruding portion in the first direction, and the first elastic member is at least partially accommodated in the groove.

[0011] In this way, the elastic connection between the mass and the first protruding portion can be achieved, and the mass can at least absorb the vibration of the bracket and / or the steering column in the first direction, and since the first elastic member is at least partially accommodated in the groove, the occupied space of the first elastic member and the mass can be reduced, and the volume of the vibration absorbing device can be reduced.

[0012] In some embodiments, in the first direction, the first protruding portion and the first elastic member are accommodated in the groove.

[0013] In this way, the occupied space of the bracket, the first elastic member and the mass can be further reduced, and the volume of the vibration absorbing device can be further reduced.

[0014] In some embodiments, in the direction perpendicular to the first direction, there is a gap between the first elastic member and the cylindrical wall, and there is a gap between the first elastic member and the groove wall.

[0015] In this way, the deformation space of the first elastic member in the direction intersecting the first direction (for example, the second direction or the third direction) can be provided, the first elastic member can be deformed in the direction intersecting the first direction (for example, the second direction or the third direction), and the vibration of the bracket or the steering column in the direction intersecting the first direction (for example, the second direction or the third direction) can be absorbed.

[0016] In some embodiments, the mass has at least one protruding portion; the protruding portion includes at least one second protruding portion; the elastic member includes at least one second elastic member; in the first direction, one end of the second elastic member is connected to the second protruding portion, and the other end of the second elastic member is connected to the protruding portion.

[0017] In this way, the elastic connection between the protruding portion and the second protruding portion can be achieved, and the function of the mass absorbing the vibration of the bracket and / or the steering column can be achieved.

[0018] In some embodiments, the plurality of protruding portions are distributed on two sides of the cylindrical wall in the radial direction, the plurality of second protruding portions are distributed on two sides of the cylindrical wall in the radial direction, and the plurality of second elastic members are distributed on two sides of the cylindrical wall in the radial direction.

[0019] Thus, the elastic connection between the protruding portion and the second protruding portion can be achieved, thereby achieving the function of absorbing the vibration of the bracket and / or the steering column by the mass block. In some embodiments, the second elastic member has a gap with the cylindrical wall in a direction perpendicular to the first direction, and the second elastic member has a gap with the mass block.

[0020] Thus, the deformation space of the second elastic member in the cross direction (e.g., the second direction or the third direction) of the first direction can be provided, and the second elastic member can be deformed in the cross direction (e.g., the second direction or the third direction) of the first direction, thereby further absorbing the vibration of the bracket or the steering column in the cross direction (e.g., the second direction or the third direction) of the first direction.

[0021] In some embodiments, the cylindrical wall is formed by a first half-cylindrical wall and a second half-cylindrical wall, the protruding portion is arranged on the first half-cylindrical wall, the first half-cylindrical wall is at least partially accommodated in the accommodation space, and the first half-cylindrical wall is connected to the shell.

[0022] Thus, as many components as possible in the vibration absorbing device can be located in the shell, thereby eliminating the interference between the mass block and the peripheral components, ensuring the reliable operation of the vibration absorber, and minimizing the occupied space of the vibration absorbing device. Moreover, since the cylindrical wall is formed by the first half-cylindrical wall and the second half-cylindrical wall, the connection difficulty of the cylindrical wall and the steering column can be reduced.

[0023] In some embodiments, the elastic member is a rubber member, both ends of the rubber member in the first direction are provided with threaded connection portions, and the rubber member is connected to the protruding portion through the threaded connection portions.

[0024] Thus, the connection of the elastic member with the bracket and the mass block can be achieved.

[0025] The second aspect of the present application provides a steering system, which comprises a steering column and the vibration absorbing device provided by the first aspect of the present application, and the steering column is connected to the bracket of the vibration absorbing device.

[0026] Thus, the vibration of the steering system can be absorbed, the stability of the steering system is improved, and the stability and comfort of the vehicle are further improved.

[0027] In some embodiments, the bracket comprises a cylindrical wall, the cylindrical wall is formed by a first half-cylindrical wall and a second half-cylindrical wall, the first half-cylindrical wall and the second half-cylindrical wall are arranged to be capable of clamping the steering column.

[0028] Thus, the difficulty of connecting the cylindrical wall and the steering column can be reduced, and reliable connection of the cylindrical wall and the steering column can be achieved.

[0029] The third aspect of the present application provides a vehicle, the vehicle comprising the steering system provided in the second aspect of the present application.

[0030] Thus, the stability and comfort of the vehicle can be improved.

[0031] In some embodiments, the vehicle is a forklift.

[0032] Thus, the stability and comfort of the forklift can be improved.

[0050] In the following, the embodiments of the present application will be described in detail.

[0051] Vehicles are more and more widely used in life and production, and with the development of technology, people have higher and higher requirements for stability and comfort during driving vehicles.

[0052] The steering system of the vehicle is the most direct perception component of the driver for the stability and comfort performance of the whole vehicle, but because the cantilever structure of the steering system is easy to amplify the vibration of the engine, how to improve the stability of the steering system has become one of the research topics in the industry.

[0053] In the prior art, a vibration absorber is usually added to the steering system to solve the problem of steering wheel vibration and improve driving comfort, but the structure of the steering system is relatively complex, and the arrangement space of the vibration absorber is often restricted. Through research, the support and the mass block can be elastically connected, and then the support and the steering column are connected. Thus, the mass block can absorb the vibration of the steering column, thereby improving the stability of the steering column and the stability of the steering system, and improving the stability and comfort of the driver during driving.

[0054] Based on such a design concept, the application designs a vibration absorbing device, which comprises: a shell having a containing space; a mass block located in the containing space; an elastic member located in the containing space; a support partially penetrating the shell and connected with the mass block through the elastic member, the mass block being movable relative to the support, and the support being used for connecting with a steering column.

[0055] Since the mass block is movable relative to the support, the mass block can absorb the vibration of the support; the support is used for connecting with the steering column, so the mass block can also absorb the vibration from the steering column. The vibration absorbing device can be applied to a steering device, thereby absorbing the vibration of the steering system, improving the stability of the steering system, and further improving the stability and comfort of the vehicle. In addition, since the vibration absorbing device comprises the shell, the mass block and the elastic member are located in the shell, the interference between the mass block and the surrounding structure can be avoided, and the service life of the mass block and the elastic member can be prolonged. Moreover, this structure is simple and can be applied to different vehicle models.

[0056] The vibration absorbing device of the application embodiment can be applied to a steering system or other systems that need to be damped.

[0057] The steering system of the application embodiment can be a mechanical steering system or a power steering system.

[0058] The vehicle of the application includes a car or a forklift, etc.

[0059] Below, with reference to Figures 1 to 4 Some embodiments of the application are described in detail.

[0060] Figure 1 A perspective view of part of the structure of the vibration absorbing device 1 provided for some embodiments of the application is shown; Figure 2 Another perspective view of part of the structure of the vibration absorbing device 1 provided for some embodiments of the application is shown; Figure 3 A perspective view of the vibration absorbing device 1 provided for some embodiments of the application is shown; Figure 4 A perspective view of the shell 11 provided for some embodiments of the application is shown.

[0061] In the description of the embodiments of the present disclosure, the first direction X is represented by the direction of arrow X, the second direction Y is represented by the direction of arrow Y, and the third direction Z is represented by the direction of arrow Z. The first direction X, the second direction Y and the third direction Z intersect with each other.

[0062] As shown in Figures 1 to 4 , the vibration absorbing device 1 of the present application comprises a shell 11 having a containing space 111, a mass block 12 located in the containing space 111, an elastic member 13 located in the containing space 111, and a support 14 partially penetrating the shell 11 and connected with the mass block 12 through the elastic member 13. The mass block 12 can move relative to the support 14, and the support 14 is used to connect with a steering column (not shown).

[0063] The material of the shell 11 is not limited in the present application. For example, the shell 11 can be made of metal.

[0064] Optionally, the shell 11 can be cylindrical or rectangular, etc. In a specific embodiment, as shown in Figure 4 , the shell 11 is rectangular.

[0065] In some embodiments, the material of the mass block 12 is not limited in the present application. The mass block 12 is made of a material with as large density as possible, so as to reduce the volume of the vibration absorbing device 1.

[0066] Since the vibration absorbing device comprises a shell, the interference between the mass block and the surrounding parts (such as wire harness) can be avoided.

[0067] In some embodiments, the outer contour of the mass block 12 can be generally cylindrical, rectangular or other irregular shapes, etc.

[0068] Optionally, the elastic member 13 can be one or more. The elastic member 13 is a part with elasticity, such as spring or rubber, etc. In a specific embodiment, the elastic member 13 is rubber.

[0069] The support 14 and the elastic member 13 can be directly connected, such as bonding or welding; or indirectly connected, such as through bolt connection.

[0070] The mass block 12 and the elastic member 13 can be directly connected, such as bonding or welding; or indirectly connected, such as through bolt connection.

[0071] Optionally, the support 14 can be made of metal or plastic, etc.

[0072] Optionally, the bracket 14 can be designed in various forms as long as it can be mounted on the steering column, for example, the bracket 14 can be a plate structure and is fixedly connected on the steering column by threaded fasteners. In a specific embodiment, as shown in Figure 3 the bracket 14 is in a cylindrical shape matching the steering column (not shown), and when mounted, the bracket 14 is directly sleeved on the outer periphery of the steering column (not shown), and is fixedly connected with the steering column by welding or fasteners. Of course, when the bracket 14 is in a cylindrical shape, the mass block 12 can also be connected with the bracket 14 in more forms.

[0073] In some embodiments, one end of the steering column can be provided with a steering wheel.

[0074] Since the mass block 12 can move relative to the bracket 14, the mass block 12 can absorb the vibration of the bracket 14; the bracket 14 is used to connect with the steering column, so the mass block 12 can also absorb the vibration from the steering column, and the vibration absorbing device 1 can be applied to the steering device, thereby absorbing the vibration of the steering system, improving the stability of the steering system, and further improving the stability and comfort of the vehicle. In addition, since the vibration absorbing device 1 includes the housing 11, the mass block 12 and the elastic member 13 are located in the housing 11, so the interference between the mass block and the surrounding structure can be avoided, and the service life of the mass block 12 and the elastic member 13 can be prolonged. And this structure is simple to set up and can be applied to different vehicle models.

[0075] In some embodiments, as shown in Figure 1 and Figure 2 the bracket 14 has a cylindrical wall 141 extending along the first direction X, the outer periphery of the cylindrical wall 141 is provided with a protruding portion 142 protruding towards the radial outer side, and the elastic member 13 is connected between the protruding portion 142 and the mass block 12 along the first direction X, and the elastic member 13 can at least elastically deform along the first direction X.

[0076] As shown in Figure 1 , since the bracket 14 has the cylindrical wall 141, when mounted, the bracket 14 can be directly sleeved on the outer periphery of the steering column (not shown). Of course, the cylindrical wall 141 can also be formed by two half-cylindrical walls (for example Figure 1 the first half-cylindrical wall 1411 and the second half-cylindrical wall 1412) as shown, so that when mounted, the steering column (not shown) can be placed in the corresponding position of one of the half-cylindrical walls (for example Figure 1 the first half-cylindrical wall 1411), and then the two half-cylindrical walls are covered to make the mounting of the bracket 14 and the steering column more convenient.

[0077] The shape of the protruding portion 142 is not limited in the present application as long as the elastic member 13 can be connected. In a specific embodiment, as shown in Figure 1and Figure 2 As shown, the protrusion 142 is plate-shaped.

[0078] Optionally, the protrusion 142 can be connected to the cylindrical wall 141 indirectly or directly. The protrusion 142 can also be connected to the cylindrical wall 141 by bolts, welding, bonding, etc. Of course, the protrusion 142 and the cylindrical wall 141 can also be integrally formed.

[0079] Optional, such as Figure 1 and Figure 2 As shown, there may be one or more protrusions 142, and different protrusions 142 may be located at the same or different heights of the outer circumference of the cylindrical wall 141 along the first direction X, or a part of the protrusions 142 (for example Figure 1 The second protrusions 1422 shown are distributed on both sides of the cylindrical wall 141.

[0080] In some embodiments, the elastic member 13 can be elastically deformed along a first direction X. Of course, the elastic member 13 can also be elastically deformed along a direction intersecting the first direction X (e.g., a second direction Y and / or a third direction Z). As a result, vibrations of the steering column can be transmitted to the mass 12 via the bracket 14 and effectively absorbed.

[0081] Because bracket 14 has cylindrical wall 141, a steering column (not shown) can be passed through cylindrical wall 141, thereby achieving a connection between cylindrical wall 141 and the steering column. Because elastic member 13 is connected between protrusion 142 and mass 12, an elastic connection between bracket 14 and mass 12 can be easily achieved, thereby enabling mass 12 to at least absorb vibration of bracket 14 and / or steering column along the first direction X. This structural design is simple.

[0082] In some embodiments, as Figure 2 As shown, the mass block 12 has a groove 121; the protrusion 142 includes a first protrusion 1421; the elastic member 13 includes at least one first elastic member 131; along the first direction X, one end of the first elastic member 131 is connected to the first protrusion 1421, and the other end of the first elastic member 131 is connected to the surface of the groove 121 opposite to the first protrusion 1421 along the first direction X, and the first elastic member 131 is at least partially received in the groove 121.

[0083] The present application does not specifically limit the shape of the groove 121. In a specific embodiment, Figure 2 As shown, the groove 121 is a "U"-shaped groove.

[0084] In some embodiments, as Figure 2 As shown, along the first direction X, the first elastic member 131 is connected between the first protrusion 1421 and the groove 121 .

[0085] In some embodiments, as shown in Figure 2 The first elastic member 131 is at least partially received in the groove 121, and of course the first elastic member 131 can be entirely received in the groove 121.

[0086] Optionally, there is one first elastic member 131, and of course there can be multiple first elastic members 131, and the multiple first elastic members 131 are respectively connected between the first protruding portion 1421 and the surface in the groove 121 opposite to the first protruding portion 1421 along the first direction X. In a specific embodiment, as shown in Figure 2 There are two first elastic members 131, and the two first elastic members 131 are spaced apart along the second direction Y.

[0087] In this way, the mass 12 and the first protruding portion 1421 can be elastically connected, and the mass 12 can at least absorb the vibration of the bracket 14 and / or the steering column along the first direction X, and since the first elastic member 131 is at least partially received in the groove 121, the occupied space of the first elastic member 131 and the mass 12 can be reduced, and the volume of the vibration absorbing device 1 can be further reduced.

[0088] In some embodiments, as shown in Figure 2 The first protruding portion 1421 and the first elastic member 131 are received in the groove 121 along the first direction X.

[0089] In this way, the occupied space of the bracket 14, the first elastic member 131 and the mass 12 can be further reduced, and the volume of the vibration absorbing device 1 can be further reduced.

[0090] In some embodiments, as shown in Figure 2 There is a gap between the first elastic member 131 and the cylindrical wall 141 along the direction perpendicular to the first direction X, and there is a gap between the first elastic member 131 and the groove wall 1211 (for example, the left groove wall and / or the right groove wall) of the groove 121. Figure 1

[0091] The size of the gap between the first elastic member 131 and the groove wall 1211 is not specifically limited in the present application, and the deformation space of the first elastic member 131 can be provided.

[0092] In this way, the deformation space of the first elastic member 131 along the cross direction (for example, the second direction Y or the third direction Z) of the first direction X can be provided, that is, the first elastic member 131 can deform along the cross direction (for example, the second direction Y or the third direction Z) of the first direction X.

[0093] ​In some embodiments, there is a gap between the bracket 14 and the mass 12 in the static state. Thus, in the vibration state, the mass 12 can generate displacement to absorb the vibration of the bracket 14. The present application does not make specific limitation on the size of the gap between the bracket 14 and the mass 12.

[0094] Thus, the deformation space of the first elastic member 131 along the cross direction (for example, the second direction Y or the third direction Z) of the first direction X can be provided, the first elastic member 131 can be deformed along the cross direction (for example, the second direction Y or the third direction Z) of the first direction X, and thus the vibration of the bracket 14 or the steering column (not shown) along the cross direction (for example, the second direction Y or the third direction Z) of the first direction X can be absorbed.

[0095] In some embodiments, as shown in Figure 1 the mass 12 has at least one protruding portion 122; the protruding portion 142 includes at least one second protruding portion 1422; the elastic member 13 includes at least one second elastic member 132; one end of the second elastic member 132 is connected to the second protruding portion 1422 along the first direction X, and the other end of the second elastic member 132 is connected to the protruding portion 122.

[0096] The mass 12 can include a mass body and the protruding portion 122, and the mass body can be connected to the protruding portion 122, which can be indirectly connected or directly connected, for example, welding or bonding, etc. In a specific embodiment, the mass body and the protruding portion 122 are integrally formed.

[0097] The present application does not make specific limitation on the shape of the protruding portion 122, as long as the second elastic member 132 can be connected. In a specific embodiment, as shown in Figure 1 the protruding portion 122 is a cuboid.

[0098] In some embodiments, as shown in Figure 1 the second elastic member 132 is connected between the second protruding portion 1422 and the protruding portion 122 along the first direction X.

[0099] In some embodiments, as shown in Figure 1 the surface of the second protruding portion 1422 connected to the second elastic member 132 is opposite to the surface of the protruding portion 122 connected to the second elastic member 132 along the first direction X.

[0100] Optionally, the protruding portion 122 can be one or more; the second protruding portion 1422 can be one or more. In a specific embodiment, as shown in Figure 1 the number of the protruding portion 122 is the same as that of the second protruding portion 1422, and the protruding portion 122 and the second protruding portion 1422 each have two. In a specific embodiment, as shown in Figure 1As shown, along the second direction Y, two of the protrusions 122 are located on two sides of the cylindrical wall 141, and two of the second protrusions 1422 are located on two sides of the cylindrical wall 141; further, along the second direction Y, the two protrusions 122 are symmetrically arranged relative to the cylindrical wall 141, and the two second protrusions 1422 are symmetrically arranged relative to the cylindrical wall 141.

[0101] Optionally, the second elastic member 132 can be one, and of course the second elastic member 132 can also be multiple, multiple second elastic members 132 can be connected to the same second protrusion 1422 and the protrusion 122 along the first direction X respectively, and multiple second elastic members 132 can also be connected to different second protrusions 1422 and protrusions 122 along the first direction X respectively. In a specific embodiment, as shown in Figure 1 The second elastic member 132 is two, and the two second elastic members 132 are symmetrically arranged relative to the cylindrical wall 141.

[0102] Thus, the elastic connection of the protrusion 122 and the second protrusion 1422 can be realized, thereby realizing the function of the mass block 12 absorbing the vibration of the support 14 and / or the steering column.

[0103] In some embodiments, as shown in Figure 1 The protrusions 122 are even, and multiple protrusions 122 are distributed on two sides of the cylindrical wall 141 in the radial direction; the second protrusions 1422 are even, and multiple second protrusions 1422 are distributed on two sides of the cylindrical wall 141 in the radial direction; and the second elastic members 132 are even, and multiple second elastic members 132 are distributed on two sides of the cylindrical wall 141 in the radial direction.

[0104] In some embodiments, as shown in Figure 1 The protrusions 122 are distributed on two sides of the cylindrical wall 141 along the second direction Y, and further, the protrusions 122 are symmetrically distributed relative to the cylindrical wall 141 along the second direction Y. Optionally, the protrusions 122 can be two, four, six, etc., and in a specific embodiment, the protrusions 122 are two and symmetrically distributed relative to the cylindrical wall 141 along the second direction Y.

[0105] In some embodiments, as shown in Figure 1 The second protrusions 1422 are distributed on two sides of the cylindrical wall 141 along the second direction Y, and further, the second protrusions 1422 are symmetrically distributed relative to the cylindrical wall 141 along the second direction Y. Optionally, the second protrusions 1422 can be two, four, six, etc., and in a specific embodiment, the second protrusions 1422 are two and symmetrically distributed relative to the cylindrical wall 141 along the second direction Y.

[0106] In some embodiments, as shown in Figure 1As shown, along the second direction Y, the second elastic members 132 are distributed on both sides of the cylindrical wall 141, and further, along the second direction Y, the second elastic members 132 are symmetrically distributed relative to the cylindrical wall 141. Optionally, the second elastic members 132 can be two, four, six, etc., and in a specific embodiment, the second elastic members 132 are two and symmetrically distributed relative to the cylindrical wall 141 along the second direction Y.

[0107] Thus, the elastic connection of the extension 122 and the second protruding portion 1422 can be achieved, thereby achieving the function of the mass 12 absorbing the vibration of the support 14 and / or the steering column.

[0108] In some embodiments, as shown in FIG. 1, the second elastic members 132 are arranged on the cylindrical wall 141, and the second elastic members 132 are arranged on the mass 12. Figure 1 As shown, along the direction perpendicular to the first direction X, there is a gap between the second elastic members 132 and the cylindrical wall 141, and there is a gap between the second elastic members 132 and the mass 12.

[0109] In some embodiments, along the direction perpendicular to the first direction X, the second elastic members 132 are spaced apart from the cylindrical wall 141, and the second elastic members 132 are spaced apart from the mass 12. For example, along the second direction Y, there is a gap between the second elastic members 132 and the cylindrical wall 141, and there is a gap between the second elastic members 132 and the mass 12. Along the third direction Z, there is a gap between the second elastic members 132 and the cylindrical wall 141, and there is a gap between the second elastic members 132 and the mass 12.

[0110] The size of the gap between the second elastic members 132 and the cylindrical wall 141 is not specifically limited in the present application, as long as it can provide a deformation space for the second elastic members 132. The size of the gap between the second elastic members 132 and the mass 12 is not specifically limited in the present application, as long as it can provide a deformation space for the second elastic members 132.

[0111] Thus, a deformation space for the second elastic members 132 along the direction intersecting the first direction X (e.g., the second direction Y or the third direction Z) can be provided, and the second elastic members 132 can be deformed along the direction intersecting the first direction X (e.g., the second direction Y or the third direction Z), thereby further absorbing the vibration of the support 14 or the steering column along the direction intersecting the first direction X (e.g., the second direction Y or the third direction Z).

[0112] In some embodiments, as shown in FIG. 1, the second elastic members 132 are arranged on the cylindrical wall 141, and the second elastic members 132 are arranged on the mass 12. Figure 2 As shown, the cylindrical wall 141 is formed by covering the first half-cylindrical wall 1411 and the second half-cylindrical wall 1412, the protruding portion 142 is arranged on the first half-cylindrical wall 1411, the first half-cylindrical wall 1411 is at least partially accommodated in the accommodation space 111, and the first half-cylindrical wall 1411 is connected to the housing 11.

[0113] In some embodiments, the protrusion 142 is located in the accommodation space.

[0114] The first half-cylindrical wall 1411 and the second half-cylindrical wall 1412 can be directly connected to form the cylindrical wall 141, for example, by being bonded together; or the first half-cylindrical wall 1411 and the second half-cylindrical wall 1412 can be indirectly connected to form the cylindrical wall 141, for example, by being bolted together. In a specific embodiment, the first half-cylindrical wall 1411 and the second half-cylindrical wall 1412 each has a protrusion portion protruding towards the radial outside, and after the first half-cylindrical wall 1411 and the second half-cylindrical wall 1412 are closed, the protrusion portion on the first half-cylindrical wall 1411 and the protrusion portion on the second half-cylindrical wall 1412 are aligned and bolted together, thereby achieving the closure of the first half-cylindrical wall 1411 and the second half-cylindrical wall 1412, and thus the steering column (not shown) can be placed in the corresponding position of the first half-cylindrical wall 1411, and then the second half-cylindrical wall 1412 is closed, so that the steering column (not shown) is tightly connected with the cylindrical wall 141.

[0115] In some embodiments, the housing 11 has an opening, and the part of the first half-cylindrical wall 1411 (for example: Figure 1 the second protrusion portion 1422 shown, or / and, Figure 2 the first protrusion portion 1421 shown) is connected with the elastic member 13 through the opening. The shape and size of the opening of the housing 11 are not specifically limited in the present application, as long as the connection between the first half-cylindrical wall 1411 and the elastic member 13 can be achieved. In a specific embodiment, the shape and size of the opening of the housing 11 match the shape and size of the first half-cylindrical wall 1411, so that almost the entire first half-cylindrical wall 1411 is located in the housing 11, thereby better protecting the first half-cylindrical wall 1411 and the components on the first half-cylindrical wall 1411.

[0116] Thus, as many components as possible in the vibration absorption device 1 can be located in the housing 11, thereby eliminating the interference between the mass and the peripheral components, ensuring the reliable operation of the vibration absorber, and minimizing the occupied space of the vibration absorption device 1. Moreover, since the cylindrical wall 141 is formed by the closure of the first half-cylindrical wall 1411 and the second half-cylindrical wall 1412, the connection difficulty between the cylindrical wall 141 and the steering column can be reduced.

[0117] In some embodiments, as shown in ​ and ​ the elastic member 13 is a rubber member, and the two ends of the rubber member along the first direction X are provided with threaded connection portions (not shown), and the rubber member is connected with the protrusion portion 142 through the threaded connection portions (not shown).

[0118] The rubber part and the threaded connection part can be directly connected or indirectly connected. The protruding part 142 has a threaded hole matched with the threaded connection part, so that the rubber part and the protruding part 142 can be connected.

[0119] Thus, the elastic part 13 can be connected with the bracket 14 and the mass 12.

[0120] The second aspect of the present application provides a steering system, which comprises a steering column (not shown) and the vibration absorbing device 1 provided by the first aspect of the present application, and the steering column (not shown) is connected to the bracket 14 of the vibration absorbing device 1.

[0121] Thus, the vibration of the steering system can be absorbed, the stability of the steering system is improved, and the stability and comfort of the vehicle are improved.

[0122] In some embodiments, the bracket 14 comprises a cylindrical wall 141, which is formed by a first half-cylindrical wall 1411 and a second half-cylindrical wall 1412, and the first half-cylindrical wall 1411 and the second half-cylindrical wall 1412 are arranged to be capable of clamping the steering column (not shown).

[0123] Thus, the difficulty of connecting the cylindrical wall 141 with the steering column (not shown) is reduced, and reliable connection of the cylindrical wall 141 with the steering column (not shown) is achieved.

[0124] The third aspect of the present application provides a vehicle, which comprises the steering system provided by the second aspect of the present application.

[0125] Thus, the stability and comfort of the vehicle are improved.

[0126] In some embodiments, the vehicle is a forklift.
