Therefore, the electric winch needs to have high reliability and stability.

[0003] In order to further improve the ease of use of the current electric winch, an electric winch with electric clutch is proposed, which requires the provision of an electric structure, but the current structure is not easy to separate, so further research is needed. Utility Model Content

The transmission shaft is connected to an electric driving structure, which is used to drive the transmission shaft to move axially to drive the second sun gear to move axially. When the transmission shaft moves axially to the left, the second sun gear moves axially to the left to separate the connecting portion from the input side planetary carrier to release the transmission connection, thereby achieving the purpose of clutch separation. When the transmission shaft moves axially to the right to reset, the second sun gear moves axially to the right to combine the connecting portion with the input side planetary carrier to restore the transmission connection, thereby achieving clutch engagement and reset. At the same time, the second ring gear is fixedly arranged to enable the second planetary carrier to output to the output side planetary gear set or the next-stage intermediate transmission planetary gear set.

[0009] In some embodiments, the planetary gear reducer includes a cover shell, a rear end cover of the cover shell is provided with a through hole, and the rear end of the cover shell is connected to a rear cover, which is axially sealed to the rear end cover, and an electromagnetic pusher is provided between the rear cover cover and the rear end cover as an electric pushing structure. After the transmission shaft passes through the input side planetary gear set, it further extends to one side of the rear end cover, so that the right end of the transmission shaft is close to or inserted into the through hole. The push rod of the electromagnetic pusher is coaxially arranged with the through hole, and the right end of the transmission shaft and the left end of the push rod can be connected against each other through the through hole.

When the push rod moves to the right, the left end of the push rod is away from the right end of the transmission shaft so that the transmission shaft can move to the right and reset, thereby achieving clutch engagement and reset.

[0010] In some embodiments, it also includes an installation cover plate, which is provided with a plug-in hole, a first connecting hole and a connecting hole connecting the through hole. The installation cover plate is fixed to the rear end cover by a first bolt and a first connecting hole, and the end of the electromagnetic pusher is provided with a plug-in protrusion that cooperates with the plug-in hole.

[0012] In some embodiments, the rear end cover is further provided with an annular retaining rib, which is axially sleeved with the mounting cover plate.

[0013] In some embodiments, the rear end cover is provided with a second connection hole on the outer periphery of the annular retaining rib, and the portion of the cover shell corresponding to the second connection hole is provided with an outward protrusion to provide a connection seat for a second bolt.

[0014] In some embodiments, a second connection hole is provided through the circumferential shell, the rear end cover and the rear cover of the cover shell, and a second bolt is connected in the second connection hole to axially connect the circumferential shell, the rear end cover and the rear cover of the cover shell.

[0015] In some embodiments, when the transmission shaft is in the initial position, the right end of the transmission shaft and the left end of the push rod are both inserted into the through hole, and the right end of the transmission shaft and the left end of the push rod are spaced apart; the initial position refers to the clutch engagement position.

[0016] In some embodiments, the drive shaft is connected to a spring and a retaining ring, and the left end of the spring is limited. When the drive shaft moves to the left, the spring is compressed by the retaining ring to store energy. At this time, the push rod moves to the left to achieve the purpose of clutch separation. When the push rod moves to the right, the left end of the push rod moves away from the right end of the drive shaft, so that the drive shaft can move to the right and reset under the action of the spring, thereby achieving clutch engagement and reset.

[0017] In some embodiments, each planetary gear set shares a common fixed ring gear.

[0018] In some embodiments, the planetary gear reducer includes a casing, and the ring gear is formed on the inner surface of the casing.

[0020] In the present disclosure, the clutch position is set in the second-stage planetary gear set, and the second sun gear is provided with a connecting part on one side of the input side planetary carrier. The axial movement of the transmission shaft drives the axial movement of the second sun gear, so that the connecting part can be easily separated from the engaged state. Since the second sun gear is axially guided by the second planetary gear, the separation process is stable and reliable. In this way, as long as the transmission shaft can move axially, it can be separated smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The embodiments described below are for example only, and those skilled in the art may think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0032] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0033] like Figures 1 to 7 As shown, the present disclosure provides an axially electric clutched electric winch, comprising an electric motor 1, a bracket 2, a hoisting drum 3 and a planetary gear reducer 4, wherein the electric motor 1 and the planetary gear reducer 4 are respectively mounted on both sides of the bracket 2, the hoisting drum 3 is rotationally connected between the brackets 2, the electric motor 1 and the planetary gear reducer 4 are connected via a transmission shaft 6, the transmission shaft 6 passes through the hoisting drum 3 to reach the input side planetary gear set 7 of the planetary gear reducer 4, and is transmission-connected with the input sun gear 8 of the input side planetary gear set 7, the input side planetary gear set 7 is located on the side away from the bracket 2, the planetary gear set of the planetary gear reducer 4 close to the bracket 2 is an output side planetary gear set 42 9 for driving the hoisting drum 3 to rotate, and also comprises an intermediate transmission planetary gear set 23, the intermediate transmission planetary gear set 23 is one or more sets, the input side planetary gear set 7, each intermediate transmission planetary gear set 23, and the output side planetary gear set 42 9 are transmission-connected and reduced in sequence along the axial direction.

[0034] Among them, the intermediate transmission planetary gear set 23 located at the input side planetary gear set 7 is recorded as the second-stage planetary gear set 24, and the second-stage planetary gear set 24 includes a second sun gear 29, a second planetary carrier 33, a second planetary gear 34 and a second ring gear 4035. The input side planetary gear set 7 includes an input side planetary carrier 36, an input side planetary gear 37, the input sun gear 8 and an input side ring gear 4038. The input sun gear 8 rotates and drives the input side planetary carrier 36 to rotate through the input side planetary gear 37. The input side ring gear 4038 is fixedly arranged to enable the input side planetary carrier 36 to output.

[0035] In addition, the second sun gear 29 is provided with a connecting portion 39 on one side of the input side planetary carrier 36. The second sun gear 29 and the transmission shaft 6 are arranged in a relatively rotatable socket connection. The transmission shaft 6 is connected to an electric propulsion structure 28, which is used to drive the transmission shaft 6 to move axially to drive the second sun gear 29 to move axially. When the transmission shaft 6 moves axially to the left, the second sun gear 29 moves axially to the left to separate the connecting portion 39 from the input side planetary carrier 36 to release the transmission connection, thereby achieving the purpose of clutch separation. When the transmission shaft 6 moves axially to the right to reset, the second sun gear 29 moves axially to the right to combine the connecting portion 39 with the input side planetary carrier 36 to restore the transmission connection, thereby achieving clutch engagement and reset. At the same time, the second ring gear 4035 is fixedly arranged to enable the second planetary carrier 33 to output to the output side planetary gear 42 group 9 or the next-stage intermediate transmission planetary gear group 23.

[0036] like Figure 2 As shown, the planetary gear reducer 4 is exemplified as having a three-stage planetary gear set, namely an input side planetary gear set 7, a set of intermediate transmission planetary gear sets 23, and an output side planetary gear set 42 9. The power transmission path is a transmission shaft 6, an input sun gear 8, an input side planetary gear 37, an input side planetary carrier 36, a second sun gear 29 integrated with a connecting part 39, a second planetary gear 34, a second planetary carrier 33, an output side sun gear 43, an output side planetary gear 42, and an output side planetary carrier 41. The output side planetary carrier 41 is connected to the right end of the winch drum 3, thereby driving the winch drum 3 to rotate.

[0037] The use of a three-stage planetary gear set and a disclosed clutch structure arrangement makes it not only easy to separate but also has a short axial dimension and a compact structure.

[0038] In some embodiments, Figure 1 , 2As shown in Figure 3, the planetary gear reducer 4 includes a housing 5, which is composed of a circumferential housing 25 and a rear end cover 10 located at one end of the circumferential housing 25. The rear end cover 10 is provided with a through hole 11. The rear end of the housing 5 is connected to a rear cover 12, which is axially sealed with the rear end cover 10. An electromagnetic pusher 13 is provided between the rear cover 12 and the rear end cover 10. The transmission shaft 6 passes through the input side planetary gear set 7 and further extends to one side of the rear end cover 10, so that the right end of the transmission shaft 6 is close to or Inserted in the through hole 11, the push rod 32 of the electromagnetic pusher 13 is coaxially arranged with the through hole 11, and the right end of the transmission shaft 6 and the left end of the push rod 32 can be connected with each other through the through hole 11. When the push rod 32 moves to the left, the left end of the push rod 32 pushes the transmission shaft 6 to move to the left through the through hole 11, thereby achieving the separation purpose of the clutch. When the push rod 32 moves to the right, the left end of the push rod 32 is away from the right end of the transmission shaft 6 so that the transmission shaft 6 can move to the right to reset, thereby achieving the clutch engagement and reset. In this way, on the one hand, through the setting of the through hole 11, the axial sealing connection between the rear cover 12 and the rear end cover 10, and the electromagnetic pusher 13 between the rear cover 12 and the rear end cover 10, convenient assembly is achieved, which is beneficial to controlling the coaxiality of the assembly and improving reliability. On the other hand, the rear cover 12 is axially sealed and connected to the rear end cover 10, and the through hole 11 of the rear end cover 10 only needs to meet the requirement that the right end of the transmission shaft 6 and the left end of the push rod 32 can be abutted and connected through the through hole 11, so the size of the through hole 11 can be smaller. In this way, the probability of foreign matter entering the planetary gear reducer 4 is greatly reduced, which is beneficial to improving reliability.

[0039] The electromagnetic pusher 13 controls the axial reciprocating motion of the push rod 32 through electromagnetic force, and the existing technology can be used, which will not be described in detail here.

[0040] In some embodiments, Figure 3 As shown, the portion of the rear end cover 10 located at the outer periphery of the annular retaining rib 21 is sleeved with a first sealing ring 27, and when the rear cover 12 is axially connected to the rear end cover 10, an axial sealing connection is performed through the first sealing ring 27. In this way, better sealing is achieved, which is beneficial to reliability.

[0041] The connecting portion 39 is configured as a spline shaft or a polygonal transmission shaft 6 or the like. Figure 8 The polygonal transmission shaft 6 is shown, which has good transmission reliability and is easy to separate. Accordingly, the input side planet carrier 36 is provided with a polygonal insertion hole 45 for clutch transmission connection. The polygonal insertion hole 45 is as shown in FIG. Fig. 9 shown.

[0042] like Figure 2As shown, in this example, the transmission shaft 6 is connected with a spring 30 and a retaining ring 31, and the left end of the spring 30 is limited. When the transmission shaft 6 moves to the left, the retaining ring 31 compresses the spring 30 to store energy. At this time, the push rod 32 moves to the left to achieve the purpose of clutch separation. When the push rod 32 moves to the right, the left end of the push rod 32 is away from the right end of the transmission shaft 6 so that the transmission shaft 6 can move to the right to reset under the action of the spring 30, thereby achieving clutch engagement reset. In this way, it is not easy to make the transmission shaft 6 stuck when resetting, that is, it is not affected by the push rod 32.

[0043] The spring 30 can store elastic potential energy in the form of tension or compression. As mentioned above, the spring 30 is in the form of compression in this example.

[0044] In some embodiments, Figure 3 , 4 As shown in , 5 and 6, it also includes a mounting cover plate 14, which is provided with a plug hole 15, a first connecting hole 16 and a connecting hole 17 connected to the through hole 11. The mounting cover plate 14 is fixed to the rear end cover 10 through a first bolt 18 and the first connecting hole 16. The end of the electromagnetic pusher 13 is provided with a plug-in protrusion 19 matched with the plug-in hole 15; the end of the electromagnetic pusher 13 is connected with the mounting cover plate 14 to form a first component 20, which is connected with the first bolt 18 and the first connecting hole 16 to fix the first component 20 on the rear end cover 10, and the plug-in protrusion 19 cooperates with the plug-in hole 15 to achieve circumferential limit to prevent the electromagnetic pusher 13 from rotating, and the left end of the push rod 32 is connected to the right end of the transmission shaft 6 through the connecting hole 17 and the through hole 11. In this way, disassembly and assembly are convenient and the connection is reliable.

[0045] Of course, other structures are also possible. For example, when the rear cover 12 is axially sealed and connected with the rear end cover 10, the electromagnetic pusher 13 is axially limited and fixed by the rear cover 12 between the mounting cover plate 14 and the rear cover 12, that is, it is also possible to consider limiting by the rear cover 12, and to achieve circumferential limiting by the plug-in protrusion 19 and the plug-in hole 15 to prevent the electromagnetic pusher 13 from rotating, and the left end of the push rod 32 is connected to the right end of the transmission shaft 6 through the connecting hole 17 and the through hole 11.

[0046] In some embodiments, Figure 3 , 4 As shown, the rear end cover 10 is also provided with an annular retaining rib 21, which is axially sleeved with the mounting cover plate 14. In this way, on the one hand, it is beneficial to production and assembly, and on the other hand, the annular retaining rib 21 can also play a function of blocking dirt from entering, thereby facilitating reliability.

[0047] In some embodiments, Figure 3 , 4As shown, the rear end cover 10 is provided with a second connection hole 22 on the outer periphery of the annular retaining rib 21, and the portion of the housing 5 corresponding to the second connection hole 22 is provided with an outward protrusion to provide a connection seat 44 for the second bolt 26. In this way, the connection strength is high, which is beneficial to reliability, and at the same time, the radial dimension of the housing 5 except for the connection seat 44 can be made smaller.

[0048] In some embodiments, Figure 2 As shown, when the transmission shaft 6 is in the initial position, the right end of the transmission shaft 6 and the left end of the push rod 32 are both inserted into the through hole 11, and the right end of the transmission shaft 6 and the left end of the push rod 32 are spaced apart. The initial position refers to the clutch engagement position. In this way, the clutch engagement position is reliable and the transmission shaft 6 is prevented from being unable to be completely reset to its original position under the influence of the push rod 32.

[0049] In some embodiments, Figure 2 As shown, each planetary gear set shares a fixed ring gear 40, which provides an input side ring gear 4038, a second ring gear 4035 and an output side ring gear 46 along the axial direction, thereby simplifying the structure and facilitating production and manufacturing.

[0050] Further, such as Figure 7 As shown, the planetary gear reducer 4 includes a housing 5, and the ring gear 40 is formed on the inner surface of the housing 5. In this way, it is not only convenient to manufacture, but also conducive to controlling the radial size of the planetary gear reducer 4.

[0051] When understanding the present invention, if necessary, the above structure can refer to other embodiments / attached Figure 1 And understand, no further elaboration here.

[0052] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any changes or substitutions that can be thought of by any person skilled in the art within the technical scope disclosed in the present disclosure should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
