DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0031] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0032] like Figure 1 , 2, 6 to 9, in the first aspect, the embodiment of the present application provides a clutch actuator, including a driving mechanism 1, the driving mechanism 1 is used to be fixed on the transfer case housing, the driving mechanism 1 can generate an axial driving force, the transmission mechanism is connected to the driving mechanism 1 through a transfer mechanism 2, so that the axial driving force of the driving mechanism 1 can be transmitted to the transmission mechanism, the transmission mechanism includes a swinging member 3 and a fixed component connected to the swinging member 3, the fixed component is in contact with the transfer case housing, the swinging member 3 can be driven by the driving mechanism 1 to reciprocate relative to the transfer mechanism 2, and can generate an axial displacement relative to the fixed component to engage or disengage the clutch, so that The embodiment of the present application only uses one component, the swing member 3, to achieve both receiving the power transmitted by the drive mechanism 1 and engaging and disengaging the clutch. Compared with the prior art, the thickness of the nut and the lever makes the thickness of the clutch actuator in the axial direction of the swing member 3 thinner, that is, the volume of the clutch actuator in the axial direction of the swing member 3 is reduced, thereby improving the space utilization rate in the transfer case housing; in addition, since the embodiment of the present application only uses the axial movement of one component, the swing member 3, to engage or disengage the clutch, compared with the prior art where the nut needs to be fixed to the lever by bolts, the installation steps are also reduced, thereby improving assembly efficiency.

[0033] like Figure 2 and 5 As shown, as an embodiment, the fixing assembly includes a fixing plate 4 and a plurality of balls. The fixing plate 4 is provided with a plurality of first grooves 31 on one side facing the swinging member 3; the swinging member 3 is provided with a plurality of second grooves 41 corresponding to the first grooves 31 on one side facing the fixing plate 4. Both the first grooves 31 and the second grooves 41 are in contact with the balls, thereby limiting the position of the balls. In addition, the first grooves 31 are directly provided on one side of the swinging member 3, so as to further reduce the space occupied by the clutch actuator in the axial direction of the fixing plate 4; the depth of the first grooves 31 gradually becomes shallower from one end to the other end. It is arranged that the ball can roll from one end of the first groove 31 to the other end, and the fixed plate 4 is connected to the transfer case housing. Therefore, the fixed plate 4 is a fixed part. Since the swinging member 3 can swing back and forth, it will drive the ball to move along the first groove 31 during the swinging process. In the process of the ball moving from one end of the first groove 31 to the other end, the ball is gradually protruding or gradually recessed in the axial direction of the fixed plate 4. For the swinging member 3, the axial protrusion and recess of the ball can also drive the swinging member 3 to move axially relative to the fixed plate 4, so as to realize the engagement or disconnection of the clutch.

[0034] Optionally, the second groove 41 can be of the same depth, and the depth of the first groove 31 gradually becomes shallower from one end to the other end. The first groove 31 and the second groove 41 are both arc-shaped grooves and are located on a circle with the same radius. When the clutch is disconnected, one end of the second groove 41 coincides with the deepest end of the first groove 31, and the other end of the second groove 41 extends away from the first groove 31. At this time, the ball is at the deepest end of the first groove 31. In the axial direction, the fixed disk 4 can fit with the swing member 3, which is equivalent to no displacement between the swing member 3 and the fixed disk 4; when the clutch needs to be engaged, the swing member 3 swings, and the overlap area of ​​the first groove 31 and the second groove 41 gradually increases. The ball can move from the deepest end of the first groove 31 to the shallowest end, axially protruding relative to the fixed disk 4, and driving the swing member 3 to axially protrude, generating displacement between the fixed disk 4, and further realizing the engagement of the clutch.

[0035] As a parallel implementation, the fixed assembly includes a fixed plate 4 and a plurality of balls. The fixed plate 4 is provided with a plurality of first grooves 31 on one side facing the swinging member 3; the swinging member 3 is provided with a plurality of second grooves 41 corresponding to the first grooves 31 on one side facing the fixed plate 4. Both the first grooves 31 and the second grooves 41 are in contact with the balls, thereby limiting the position of the balls. In addition, the first grooves 31 are directly provided on one side of the swinging member 3, so as to further reduce the space occupied by the clutch actuator in the axial direction of the fixed plate 4; the depth of the second grooves 41 gradually becomes shallower from one end to the other end. It is arranged that the ball can roll from one end of the second groove 41 to the other end, and the fixed plate 4 is connected to the transfer case housing. Therefore, the fixed plate 4 is a fixed part. Since the swinging member 3 can swing back and forth, it will drive the ball to move along the second groove 41 during the swinging process. In the process of the ball moving from one end of the second groove 41 to the other end, the ball is gradually protruding or gradually recessed in the axial direction of the fixed plate 4. For the swinging member 3, the axial protrusion and recess of the ball can also drive the swinging member 3 to move axially relative to the fixed plate 4, thereby realizing the engagement or disconnection of the clutch.

[0036] Optionally, the first groove 31 can be of the same depth, and the depth of the second groove 41 is gradually shallower from one end to the other end. The first groove 31 and the second groove 41 are both arc-shaped grooves and are located on a circle with the same radius. When the clutch is disconnected, one end of the first groove 31 coincides with the deepest end of the second groove 41, and the other end of the first groove 31 extends away from the second groove 41. At this time, the ball is at the deepest end of the first groove 31. In the axial direction, the fixed disk 4 can fit with the swing member 3, which is equivalent to no displacement between the swing member 3 and the fixed disk 4; when the clutch needs to be engaged, the swing member 3 swings, and the area of ​​the first groove 31 and the second groove 41 overlap gradually increases. The ball can move from the deepest end of the second groove 41 to the shallowest end, axially protruding relative to the fixed disk 4, and driving the swing member 3 to axially protrude, generating displacement between the fixed disk 4, and further realizing the engagement of the clutch.

[0037] like Figure 2 and 5 As shown, as an embodiment, the fixing assembly includes a fixing plate 4 and a plurality of balls. The fixing plate 4 is provided with a plurality of first grooves 31 on one side facing the swinging member 3; the swinging member 3 is provided with a plurality of second grooves 41 corresponding to the first grooves 31 on one side facing the fixing plate 4. Both the first grooves 31 and the second grooves 41 are in contact with the balls, thereby limiting the position of the balls. In addition, the first groove 31 is directly provided on one side of the swinging member 3, so as to further reduce the space occupied by the clutch actuator in the axial direction of the fixing plate 4; the depths of the first grooves 31 and the second grooves 41 are gradually shallowed from one end to the other end, so that when the balls roll, the axial displacement of the swinging member 3 can be further increased, thereby reducing the axial force generated by the driving mechanism 1 and reducing energy consumption.

[0038] When the clutch is disconnected, the first ends of the corresponding groups of first grooves 31 and second grooves 41 coincide with each other, that is, the deepest ends coincide with each other, so that the ball is at the deepest ends of the first grooves 31 and the second grooves 41, and there is no displacement between the swinging member 3 and the fixed plate 4. The second ends of the first grooves 31 and the second ends of the second grooves 41 extend away from each other, that is, the shallowest ends of the first grooves 31 and the second grooves 41 do not coincide with each other. The depth of the first ends of the first grooves 31 and the second grooves 41 is greater than the depth of the second ends. In the process of gradual swinging of the swinging member 3, which is also the process of engaging the clutch, the ball rolls in the first grooves 31 and the second grooves 41, and the overlapping area of ​​the first grooves 31 and the second grooves 41 gradually increases. In the process of rolling in the second grooves 41, the ball also rolls from deep to shallow and axially protrudes relative to the fixed plate 4. At the same time, the first grooves 31 also roll from deep to shallow, thereby further increasing the axial displacement of the swinging member 3 and achieving engagement with the clutch. At the same time, the number of parts of the clutch actuator is reduced, the assembly difficulty is reduced, and the axial thickness is also reduced.

[0039] Optionally, the embodiment of the present application can reduce the number of installation steps and provide structural stability by cooperating between the swinging member 3 and the fixed disk 4, compared with fixing the nut on the lever. In addition, a first groove 31 is directly opened on the swinging member 3, which is equivalent to the swinging member 3 being able to swing and move. Compared with the connection between the lever and the nut in the prior art, the axial thickness can be reduced and the occupied volume can be reduced.

[0040] Optionally, when the clutch is disengaged, the swing member 3 may be coaxial with the adapter block 21 , and when the clutch is engaged, the swing member 3 may swing relative to the adapter block 21 .

[0041] Optionally, the fixed disk 4 is annular so that the transfer case input shaft can pass through it.

[0042] like Figure 2 and 4 As shown, optionally, a second connecting bearing 6 is further provided on one side of the swing member 3, and the second connecting bearing 6 is in contact with the clutch. When the swing member 3 is in the initial position, the clutch can be in a disconnected state. When the swing member 3 produces an axial displacement, it can also push the second connecting bearing 6, and the second connecting bearing 6 is in contact with the clutch, thereby realizing the engagement of the clutch; when the clutch needs to be disconnected, the swing member 3 swings back to the initial position in the opposite direction, and the ball also rolls to the deepest position of the first groove 31 and the second groove 41. At the same time, the clutch return spring pushes the second connecting bearing 6 in the opposite direction, and the second connecting bearing 6 is separated from the clutch, and the clutch is in a disconnected state. By providing the second connecting bearing 6, the friction loss between the clutch and the swing member 3 can be reduced.

[0043] As an implementation mode, the first groove 31 and the second groove 41 are both arc-shaped to facilitate the rolling of the ball, and the multiple first grooves 31 and the multiple second grooves 41 are all on a circle with the same radius, so that the swing member 3 can swing relative to the fixed plate 4 to produce axial displacement.

[0044] like Figure 2 As shown, as an embodiment, the outer surface of the fixed plate 4 is used to adapt to the inner hole of the transfer case housing to achieve radial fixation of the fixed plate 4. The fixed plate 4 is also provided with a radially protruding limit block 42, and the limit block 42 is used to adapt to the groove on the transfer case housing, thereby limiting the circumferential rotation of the fixed plate 4.

[0045] like Figure 1 , 2 As shown in Figure 4, as an embodiment, the adapter mechanism 2 includes an adapter block 21, and the adapter block 21 is provided with a through elongated hole 211. By setting the elongated hole 211, a movable space can be provided for the swing member 3, and the swing member 3 can produce axial displacement in the direction; the swing member 3 includes an integrally formed cantilever and a swing ring connected to the cantilever, so as to improve the structural stability of the swing member 3, and a cylindrical pin 32 is provided at one end of the cantilever, and a bearing 33 is sleeved on the outer surface of the cylindrical pin 32, and the outer ring of the bearing 33 contacts the elongated hole 211, so as to limit the swing member 3 relative to the width direction of the elongated hole 211, and at the same time, the swing member 3 can swing relative to the adapter block 21, and reduce the wear between the cylindrical pin 32 and the adapter block 21.

[0046] like Figure 3 , 7 As shown in FIG. 9 , optionally, the adapter mechanism 2 further includes a piston shaft bolt 22 , which fixes the adapter block 21 to one end of the piston shaft 12 , and the piston shaft bolt 22 is coaxial with the piston shaft 12 .

[0047] like Figure 2 and 4 As shown, optionally, a retaining ring 34 is fixed to one end of the cylindrical pin 32 to limit the axial position of the bearing 33 and prevent the bearing 33 from falling off the cylindrical pin 32 .

[0048] Optionally, the swing ring can be used to allow the transfer case input shaft to pass through, and the swing ring is provided with a plurality of first grooves 31 .

[0049] like Figure 1 and 2As shown, as an embodiment, the driving mechanism 1 includes a power cylinder assembly, which includes a cylinder body 13 and a piston 11 located in the cylinder body 13. The piston 11 is connected to the adapter block 21. The piston 11 can move axially along the cylinder body 13, thereby driving the adapter block 21 to move synchronously. The movement of the adapter block 21 will drive the cantilever to swing synchronously, and the swing ring will produce axial displacement due to the limitation of the fixed plate 4 and the ball, thereby realizing the transmission of the driving force of the piston 11 to the swing member 3.

[0050] like Figure 1 and 2 As shown, optionally, the power cylinder assembly further includes a rear cover 14 , which is connected to the cylinder body 13 by bolts, and a sealing gasket 15 is also provided between the rear cover 14 and the cylinder body 13 to ensure the sealing of the chamber in the cylinder body 13 .

[0051] like Figure 2 and 3 As shown, optionally, two first sealing rings 16 are spaced apart on the outer surface of the piston 11 . By providing two first sealing rings 16 , the sealing performance in the cylinder body 13 can be further improved.

[0052] Optionally, a power cylinder assembly is used as the driving mechanism 1, which has a simpler structure, more reliable operation and lower cost compared with the actuator motor assembly and the electromagnet assembly in the prior art.

[0053] like Figure 2 and 3 As shown, optionally, the drive mechanism 1 also includes a displacement sensor magnet 7, which is placed in a cylindrical groove of the piston 11. When the piston 11 moves, the displacement sensor magnet 7 moves with the piston 11, so that the displacement sensor fixed on the transfer case housing can monitor the position of the piston 11 in real time through the displacement sensor magnet 7, thereby realizing feedback on the clutch operation command, and then feeding back the actual clamping position of the clutch.

[0054] like Figure 1 and 2 As shown, as an embodiment, a clutch engagement control hole 131 and a clutch disengagement control hole 132 are provided on the cylinder body 13. The clutch engagement control hole 131 and the clutch disengagement control hole 132 are respectively connected to the two ends of the chamber in the cylinder body 13. When air pressure or hydraulic pressure is injected into the clutch engagement control hole 131 and the clutch disengagement control hole 132, the piston 11 can be moved axially in different directions. The movement of the piston 11 will drive the swinging member 3 to swing, thereby realizing the engagement or disengagement of the clutch.

[0055] Optionally, the air pressure source and the hydraulic pressure source can be selected from those provided on the vehicle.

[0056] like Figures 1 to 3As shown, as an embodiment, the driving mechanism 1 also includes a piston shaft 12, one end of the piston shaft 12 is connected to the adapter block 21, and the other end passes through the piston 11 and is connected to the piston 11. By setting the piston shaft 12, the axial thrust of the piston 11 can be transmitted to the adapter block 21, and then transmitted to the swing member 3 by the adapter block 21.

[0057] Optionally, the adapter block 21 is perpendicular to the piston shaft 12. This arrangement ensures that after the power of the piston shaft 12 and the piston 11 is transmitted to the swing member 3, the swing member 3 can transmit torque to the fixed plate 4, which is finally converted into a thrust in the axial direction of the fixed plate 4 that is perpendicular to the axial direction of the piston shaft 12, thereby improving the practicality of the clutch actuator.

[0058] like Figure 2 and 3 As shown, optionally, a second sealing ring 17 is provided between the piston shaft 12 and the cylinder body 13 to improve the sealing inside the cylinder body 13; a third sealing ring 18 is provided between the piston shaft 12 and the piston 11 to ensure the sealing between the piston shaft 12 and the piston 11.

[0059] like Figure 2 and 3 As shown, optionally, the piston shaft 12 is connected to the piston 11 via a piston bolt 19 .

[0060] like Figure 2 and 3 As shown, optionally, a bushing 8 is provided at the position where the piston shaft 12 passes through the cylinder body 13 . The bushing 8 is arranged on the outer periphery of the piston shaft 12 . The bushing 8 can reduce the wear of the piston shaft 12 . The piston shaft 12 is also provided with a bushing retaining ring 81 for axially limiting the bushing 8 .

[0061] like Figure 1 , 2 As shown in 4, as an embodiment, the transmission mechanism also includes a first connecting bearing 5, one end of which is fitted with the fixed plate 4, and the other end is used to cooperate with the gasket plane on the transfer shaft to limit the fixed plate 4, so as to limit the axial position of the fixed plate 4. At the same time, the wear between the fixed plate 4 and the gasket is reduced, thereby improving the transmission efficiency.

[0062] In a second aspect, an embodiment of the present application further provides a vehicle, comprising a clutch actuator provided in the first aspect, the vehicle being capable of reducing noise while also improving the cooling efficiency of the end winding.
