Shock absorbers have wide application in practical production and manufacture. For example, the shock absorber may comprise an automotive shock absorber.

For example, in the automotive industry, shock absorbers for automobiles may include shock absorbing members and strut members, through which the shock absorber may be connected to a vehicle frame. The shock absorbing member is located on a side of the strut member remote from the frame and is connected to the vehicle body by a top end connector. For example, the shock absorbing members of the shock absorber include spring members that compress when the vehicle body is subjected to a downward pressure near the frame; when the downward pressure is cancelled, the automobile body will return to rebound, and the rebound of the shock absorber to the spring plays a damping role at the moment so as to avoid the spring to be compressed and rebound for a plurality of times, and the automobile body tends to be stable after rebound for a plurality of times. The shock absorber can play a role in damping shock absorption when the spring rebounds. In addition, a bearing member is provided between the tip end connector of the damper and the spring. For example, when the wheels of an automobile rotate, the bearing members of the shock absorber may effect axial rotation of the shock absorber relative to the vehicle body.

In research, the inventors of the present application found that only one bearing member is provided between the strut member and the spring in the existing automotive shock absorber, and that the bearing member needs to withstand the pressure from between the vehicle body and the vehicle frame and achieve the rotation of the shock absorber relative to the vehicle body. Therefore, the risk of failure of the bearing components during long-term use of the shock absorber is greater, and the service life thereof is shorter, thereby possibly affecting the performance of the shock absorber.

At least one embodiment of the present utility model provides a shock absorber connection assembly including a fixed end cap, a shock isolation mount, a body portion, and first and second bearings. The shock insulation mounting seat is connected with the fixed end cover; the main body part is configured to be connected with the shock absorber, the main body part comprises a first mounting seat, the first mounting seat comprises a protruding part, and the protruding part protrudes radially relative to the first mounting seat; the first bearing and the second bearing are respectively positioned at two sides of the protruding part along the axial direction of the first mounting seat. The fixed end cover comprises a first part and a second part which are connected with each other, the shock insulation installation seat comprises a third part and a fourth part which are connected with each other, and the second part of the fixed end cover is connected with the fourth part of the shock insulation installation seat. In the axial direction of the first mount, the projection is located between the first portion of the fixed end cap and the third portion of the shock-insulating mount, the first bearing is located between the first portion of the fixed end cap and the projection, the second bearing is located between the third portion of the shock-insulating mount and the projection, and the first portion of the fixed end cap and the third portion of the shock-insulating mount overlap at least partially in the axial direction of the first mount.

According to the shock absorber connecting assembly provided by at least one embodiment of the utility model, through the arrangement of the two bearings, the steering torque of the shock absorber connecting assembly can be improved, the activity performance of the shock absorber connecting assembly can be improved, and the service life of the bearings can be prolonged.

The damper connection assembly and the damper assembly are described below with reference to the drawings and by way of some embodiments.

FIG. 1 is a perspective view of a shock absorber attachment assembly provided in accordance with at least one embodiment of the present utility model; FIG. 2 is a side view of a shock absorber attachment assembly provided in accordance with at least one embodiment of the present utility model; FIG. 3 is a cross-sectional view of a shock absorber attachment assembly provided in accordance with at least one embodiment of the present utility model.

Referring to fig. 1 and 2, the shock absorber connection assembly 01 includes a fixed end cap 10, a shock insulation mount 11, and a main body 12. The shock insulation mount 11 is connected to the fixed end cap 10, and the main body 12 is configured to be connected to a shock absorber.

Referring to fig. 3, the main body 12 includes a first mount 13, the first mount 13 includes a protrusion 14, and the protrusion 14 protrudes radially with respect to the first mount 13.

Referring to fig. 3, the damper connecting assembly 01 further includes a first bearing 15 and a second bearing 16, the first bearing 15 and the second bearing 16 being located at both sides of the protruding portion 14 in the axial direction X of the first mount 13, respectively.

Referring to fig. 3, the stationary end cap 10 includes a first portion 17 and a second portion 18 that are connected to each other, the shock insulation mount 11 includes a third portion 19 and a fourth portion 20 that are connected to each other, and the second portion 18 of the stationary end cap 10 is connected to the fourth portion 20 of the shock insulation mount 11.

Referring to fig. 3, in the axial direction X of the first mount 13, the projection 14 is located between the first portion 17 of the fixed end cap 10 and the third portion 19 of the shock-insulating mount 11, at least part of the first bearing 15 is located between the first portion 17 of the fixed end cap 10 and the projection 14, at least part of the second bearing 16 is located between the third portion 19 of the shock-insulating mount 11 and the projection 14, and the first portion 17 of the fixed end cap 10 and the third portion 19 of the shock-insulating mount 11 overlap at least part in the axial direction X of the first mount 13.

For example, referring to fig. 1 and 2, the stationary end cap 10 is located at the top end of the shock absorber attachment assembly 01 and is configured to be attached to the vehicle body by the attachment member 40. For example, the number of the connection members 40 may be 3, but is not limited thereto. For example, the shock insulation mount 11 and the fixed end cap 10 are connected by the connection member 41 so that there is no relative movement between the shock insulation mount 11 and the fixed end cap 10. For example, the number of the connection members 41 may be 6 to 20, but is not limited thereto. For example, the connection members 40 and 41 may be bolts, but are not limited thereto.

For example, referring to fig. 3, at least one of screwing, welding and riveting may be performed between the second portion 18 of the fixed end cap 10 and the fourth portion 20 of the shock insulation mounting seat 11, which is not limited by the embodiment of the present utility model, and may be selected according to design requirements.

For example, referring to fig. 3, the body portion 12 may include a first mount 13 and a plurality of connection members within the first mount 13, and at least part of the damper may be connected with the plurality of connection members. For example, the first mount 13 may serve as an outer housing of the main body 12. For example, the first mount 13 may be cylindrical. For example, the protrusion 14 may be integrally formed with a portion of the first mount 13 excluding the protrusion 14, but is not limited thereto. The projection 14 is spaced apart from the shock-insulating mount 11 such that the projection 14 is movable relative to the shock-insulating mount 11.

For example, referring to fig. 3, the first portion 17 of the fixed end cap 10 may be a portion opposite to the protrusion 14 in the axial direction X of the first mount 13, and at least a portion of the first bearing 15 is located between the first portion 17 and the protrusion 14, whereby relative rotation therebetween is enabled. The second portion 18 of the stationary end cap 10 may be the portion that is connected to the shock isolation mount 11. For example, the first portion 17 is integrally formed with the second portion 18, but is not limited thereto.

For example, referring to fig. 3, the third portion 19 of the shock insulation mount 11 may be a portion opposite to the projection 14 in the axial direction X of the first mount 13, and at least a portion of the second bearing 16 is located between the third portion 19 and the projection 14, whereby relative rotation therebetween can be achieved. For example, the third portion 19 is integrally formed with the fourth portion 20, but is not limited thereto.

Referring to fig. 3, the first portion 17 of the stationary end cap 10 at least partially overlaps the third portion 19 of the shock insulation mount 11 in the axial direction X of the first mount 13. For example, in the axial direction X of the first mount 13, when the first mount 13 in the damper connecting assembly 01 receives a force in a direction away from the fixed end cap 10, the pressure received by the second bearing 16 will be greater than the pressure received by the first bearing 15; conversely, when the first mount 13 in the damper connection assembly 01 is subjected to a force in the direction toward the fixed end cap 10, the first bearing 15 will be subjected to a greater pressure than the second bearing 16. Thus, in the axial direction X of the first mount 13, the stress of the damper connecting assembly 01 can be distributed over the first bearing 15 and the second bearing 16, as compared to providing only one bearing between the fixed end cap 10 and the main body 12.

Therefore, the shock absorber connecting assembly 01 provided by the embodiment of the utility model can improve the steering flexibility of the shock absorber connecting assembly 01, optimize the activity performance of the shock absorber connecting assembly and prolong the service lives of the first bearing 15 and the second bearing 16 by arranging two bearings.

FIG. 4 is a perspective view of a first mount provided in at least one embodiment of the present disclosure; fig. 5 is a side view of a first mount provided in at least one embodiment of the present utility model.

For example, referring to fig. 4 and 5, the first mount 13 further includes a plurality of contact blocks 21, and the plurality of contact blocks 21 are disposed outside the first mount 13 and along the circumferential direction of the first mount 13. For example, the distance between the side of the plurality of contact blocks 21 away from the protruding portion 14 and the protruding portion 14 in the axial direction X of the first mount 13 is M.

For example, referring to fig. 3, the plurality of contact blocks 21 are located on a side of the projection 14 remote from the first bearing 15. The second bearing 16 is located on a side of the plurality of contact blocks 21 away from the first mount 13 in the radial direction of the first mount 13, and one end of the plurality of contact blocks 21 away from the protruding portion 14 is farther from the protruding portion 14 than the third portion 19 of the shock-insulating mount 11 in the axial direction X of the first mount 13.

For example, the projection 14 may receive a force in the axial direction X from the first mount 13 through the plurality of contact blocks 21. For example, an elastic member may be provided at an end of the contact block 21 remote from the projection 14. For example, the elastic member may be a spring, and in this case, the force in the axial direction X from the first mount 13 may be the elastic force of the spring. By causing a force in the axial direction X from the first mount 13 to act on the plurality of contact blocks 21 adjacent to the second bearing 16, the risk of failure of the second bearing 16 can be reduced.

For example, referring to fig. 3, the second bearing 16 includes a first housing portion 22, a second housing portion 23, and a sliding support portion 24, the sliding support portion 24 being located between the first housing portion 22 and the second housing portion 23, the first housing portion 22 being located on a side of the sliding support portion 24 near the projecting portion 14, the second housing portion 23 being located on a side of the sliding support portion 24 near the third portion 19 of the shock-insulating mount 11. The first housing portion 22 includes a buffer portion 25, the buffer portion 25 is located on a side of the first housing portion 22 near the protruding portion 14, and the buffer portion 25 is in interference fit with the protruding portion 14.

For example, referring to fig. 3, the buffer portion 25 of the first housing portion 22 is an interference fit with the projection 14, and the buffer portion 25 may be a portion of the first housing portion 22 adjacent to the projection 14. For example, the buffer 25 may include an elastic material. For example, the material of the portion of the first housing portion 22 other than the buffer portion 25 may be the same as that of the second housing portion 23, and may be a rigid material, for example. For example, the buffer 25 may include an elastic rubber body, but is not limited thereto, and embodiments of the present utility model are not limited to the type of elastic material.

For example, referring to fig. 3, by providing the buffer portion 25, it is possible to alleviate the impact between the first mount 13 and the second bearing 16 and reduce abnormal sounds generated due to the impact, to protect the device.

For example, referring to fig. 3, the first bearing 15 is L-shaped in cross section along a plane passing through the rotation axis R of the main body 12. For example, a part of the L-shape is located between the first portion 17 of the fixed end cap 10 and the first mount 13 in the radial direction of the first mount 13, and another part of the L-shape is located between the second portion 18 of the fixed end cap 10 and the projection 14 in the axial direction X of the first mount 13.

Thereby, it is possible to make the contact area between the first bearing 15 and the main body portion 12 distributed in the axial direction X of the first mount 13 and in the radial direction of the first mount 13, thereby increasing the contact area between the first bearing 15 and the first mount 13 and the fixed end cover 10, so that the activity of the first bearing 15 is enhanced and the relative rotation between the first mount 13 and the fixed end cover 10 is better achieved.

For example, referring to fig. 3, the first bearing 15 and the second bearing 16 may each be a planar bearing, but are not limited thereto. When the first bearing 15 and the second bearing 16 employ a planar bearing, high-precision rollers (e.g., cylindrical needle rollers) in the planar bearing can increase the contact area, so that the first bearing 15 and the second bearing 16 can obtain high load capacity and high rigidity in a smaller space, and the life of the first bearing 15 and the second bearing 16 is longer. Further, in the damper connecting assembly 01, the first bearing 15 and the second bearing 16 may be in direct contact with the contact surface, whereby some structures (e.g., washers, etc.) may be omitted, so that the design structure is more compact.

Fig. 6 is a cross-sectional view of a first mount provided in at least one embodiment of the present utility model.

For example, referring to fig. 6, the first mount 13 further includes a support portion 26, and the support portion 26 is located inside the first mount 13. The support portion 26 is provided along the circumferential direction of the first mount 13, and the support portion 26 includes a passage 261 so that the inside of the first mount 13 is penetrated.

For example, referring to fig. 3, the body portion 12 further includes a bushing assembly 27 and an inner cover 28. The bushing assembly 27 and the inner cover 28 are located inside the first mount 13, and the inside of the bushing assembly 27, the inside of the inner cover 28, and the inside of the first mount 13 communicate with each other.

For example, referring to fig. 3, a bushing assembly 27 and an inner cover 28 are sequentially provided on a side of the support portion 26 near the fixed end cap 10, and the inner cover 28 is connected with the first mounting seat 13.

For example, referring to fig. 3, the bushing assembly 27 may include a first bushing portion 271 and a second bushing portion 272, with the first bushing portion 271 and the second bushing portion 272 being connected. For example, the first sleeve portion 271 may include an elastic material (e.g., rubber). For example, the second bushing portion 272 may include a rigid material (e.g., steel, etc.). For example, the bushing assembly 27 includes a channel 273 such that the interior of the bushing assembly 27 is through-going in its axial direction. For example, one end of the damper may be inserted into the interior of the bushing assembly 27 through the passage 273 and connected to the second bushing portion 272 through the spacing washer 35 and the fastener, but is not limited thereto.

For example, referring to FIG. 3, the inner cover 28 is located on the side of the liner assembly 27 adjacent the stationary end cap 10. For example, the inner cover 28 may be screwed with the first mount 13, but is not limited thereto. For example, the side of the inner cover 28 adjacent to the fixed end cap 10 is also provided with a spacing washer 36 and a snap ring 37 to further enhance the mounting security of the inner cover 28. For example, the provision of the bushing assembly 27 may protect the components inside the first mount 13 and reduce the chance of impurities falling into the interior of the first mount 13.

For example, referring to fig. 3, the inner cover 28 further includes a passage 281 such that the inside of the inner cover 28 is through-going in its axial direction. At this time, the passage 261, the passage 273, and the passage 281 communicate with each other so that the inside of the liner assembly 27, the inside of the inner cover 28, and the inside of the first mount 13 communicate with each other.

For example, referring to fig. 5 and 6, the outer wall of the first mount 13 is provided with a first annular groove 29, and the first annular groove 29 is located on the side of the plurality of projections 14 remote from the fixed end cap 10 (refer to fig. 3). The contact block 21 is located between the first annular groove 29 and the projection 14.

For example, referring to FIG. 3, the outer wall of the bushing assembly 27 is provided with a second annular groove 30. The second annular grooves 30 are provided in 2 and distributed in the axial direction of the bush assembly 27. For example, the first annular groove 29 or the second annular groove 30 may be provided in 1 or more, for example, 3, but is not limited thereto. The embodiment of the present utility model is not limited in the number and positions of the first annular groove 29 and the second annular groove 30.

For example, referring to fig. 3, the shock absorber joint assembly 01 further includes a first seal 31 and a second seal 32. For example, the first seal 31 is located in the first annular groove 29 and is interference fit with the first annular groove 29 to achieve a good seal between the first mount 13 and other components (not shown, e.g., spring components). For example, the second seal 32 is located in the second annular groove 30. The second seal 32 is an interference fit with the second annular groove 30 to achieve a good seal between the first mount 13 and the bushing assembly 27.

For example, referring to FIG. 3, a shock absorber attachment assembly 01 may be engaged with a spring member. For example, the spring member may comprise a steel spring member or an air spring member. For example, when the damper connecting assembly 01 is mated with an air spring member, the air spring member may be disposed outside the first mount 13 on a side of the contact block 21 remote from the projection 14. The provision of the first seal 31 can enhance the sealing performance between the first mount 13 and the air spring member. For example, the spring member communicates with the interior of the first mount 13 and the provision of the second seal 32 may enhance a good seal between the first mount 13 and the bushing assembly 27.

For example, referring to fig. 3, in order to improve sealability between the damper connecting assembly 01 and the damper, a third seal 38 and a fourth seal 39 may be further provided inside the second bushing portion 272 so that a good sealing effect is provided between the damper and the second bushing portion 272. For example, the inner wall of the second sleeve portion 272 may be provided with a third annular groove 33, and the third annular groove 33 is located at an end of the second sleeve portion 272 near the end cap portion 10. For example, the third seal 38 and the fourth seal 39 may each be located within the third annular groove 33. For example, the third seal 38 may be provided in 1, and the fourth seal 39 may be provided in 2. For example, in the axial direction X of the first mount 13, the third seal 38 may be located between two fourth seals 39, but is not limited thereto.

For example, the first seal 31, the second seal 32, the third seal 38, and the fourth seal 39 may include an elastic material, such as rubber. For example, the first sealing member 31, the second sealing member 32, the third sealing member 38 and the fourth sealing member 39 may be O-shaped rubber rings, and the volume of the O-shaped rubber rings may be selected according to actual design requirements, which is not limited.

For example, referring to FIG. 3, at least one embodiment of the present utility model provides a damper connection assembly 01 that can be used with both air spring dampers and steel spring dampers. For example, when the damper connecting assembly 01 is matched with an air spring damper, the first sealing member 31, the second sealing member 32, the third sealing member 38 and the fourth sealing member 39 are required to be disposed at corresponding positions in order to achieve a good sealing effect. For example, when the damper connecting assembly 01 is mated with a steel spring damper, the plurality of seals may be omitted as appropriate according to actual design requirements, thereby enabling the damper connecting assembly 01 to be generalized.

FIG. 7 is a cross-sectional view of a shock absorber assembly provided in accordance with at least one embodiment of the present utility model.

Referring to fig. 7, at least one embodiment of the present utility model further provides a damper assembly 02, wherein the damper assembly 02 includes the damper connection assembly 01 and the damper 50 provided in any of the above embodiments, and the damper 50 is connected with the main body 12.

For example, referring to fig. 7, the damper 50 may extend into the interior of the first mount 13 along the axial direction X of the first mount 13 and be connected to the bushing assembly 27 in the body portion 12 by fasteners 42. For example, the fastener 42 may be a bolt, but is not limited thereto.

The shock absorber assembly 02 provided by the embodiment of the utility model can improve the steering flexibility of the shock absorber connecting assembly 01 in the shock absorber assembly 02, optimize the activity performance of the shock absorber connecting assembly 01 and prolong the service life of the first bearing 15 and the second bearing 16 by arranging two bearings (for example, the first bearing 15 and the second bearing 16).

For example, referring to fig. 7, in shock absorber assembly 02, shock absorber 50 includes spring structure 51, spring structure 51 being located on a side of shock isolation mount 11 remote from fixed end cap 10.

For example, referring to fig. 7, one end of the spring structure 51 is connected to the outer wall of the first mount 13. For example, the rotation axis of the spring structure 51 coincides with the rotation axis of the first mount 13.

For example, referring to fig. 7, the spring structure 51 includes a spring mounting portion 511 and a spring body portion 512. One end of the spring main body portion 512 is connected to the spring mounting portion 511, and is connected to the outer wall of the first mount 13 via the spring mounting portion 511. For example, the spring body 512 is in a compressed state, and the spring mounting portion 511 may be in close contact with the plurality of contact blocks 21 in the first mounting seat 13 under the elastic force of the spring body 512, so as to achieve the fixation with the first mounting seat 13, but not limited thereto, the fixation manner of the spring structure 51 is not limited in the embodiment of the present utility model.

For example, the spring structure 51 may be a steel spring or an air spring. The way in which the seal member is selected for cooperation with the steel spring or the air spring is described in the above embodiments, and will not be described in detail. Therefore, the shock absorber assembly 02 provided by the embodiment of the utility model can meet the universal installation requirement for the steel spring and the air spring, so that the shock absorber assembly 02 is suitable for more application scenes and has higher use value.

For example, shock absorber 50 may be a dual-acting barrel shock absorber, with the shock absorbing components in shock absorber 50 further comprising a working cylinder 52. For example, the other end of the spring body 512 is connected to the outer wall of the cylinder block 52. For example, in the cylinder block 52, there may be provided a piston rod 53, an upper chamber, a lower chamber, an extension valve and a flow valve between the upper chamber and the lower chamber, and a compression valve and a compensation valve at the bottom of the working chamber, etc. (not shown), which are used to control the flow of oil between the upper chamber and the lower chamber.

For example, when the shock absorber 50 is compressed, the piston rod 53 descends, the upper chamber volume increases, the lower chamber volume decreases, the circulation valve opens, and the oil of the lower chamber enters the upper chamber through the circulation valve; at the same time, a part of oil opens the compression valve to enter the oil storage cylinder. The restriction of the oil by the flow and compression valves may provide damping of the compression motion of shock absorber 50. For example, when the shock absorber 50 is extended, the piston rod 53 moves upward, the upper chamber volume decreases, the lower chamber volume increases, the extension valve opens, and the oil of the upper chamber enters the lower chamber through the extension valve; meanwhile, a part of oil opens the compensation valve and enters the lower cavity from the oil storage cylinder. The expansion valve and the compensation valve can throttle oil to make the shock absorber produce damping action during expansion movement, but is not limited to the damping action.
