Description
Technical Field
[0001] This invention belongs to the field of winch technology, specifically relating to a motor-embedded integrated electric winch. Background Technology
[0002] Winches are a commonly used traction tool, frequently used in daily life for pulling heavy objects. For example, winches are mounted on vehicles for roadside assistance. Currently, winches with higher pulling capacity tend to be larger, which limits their installation range. Traditional winches have the motor and reducer mounted on opposite sides of the drum, connected by a transmission rod. This type of winch is often too long along the drum's axial length, resulting in a longer transmission component connecting the reducer and motor, leading to low motor transmission efficiency. Therefore, there is a need to design a smaller, more efficient winch with an embedded motor. Summary of the Invention
[0003] This invention addresses the problems existing in the prior art by designing a motor-embedded integrated electric winch. The invention significantly shortens the length of the winch by embedding the motor, and the embedded motor is directly connected to the reducer assembly, which greatly improves the transmission efficiency of the motor.
[0004] The objective of this invention is achieved through the following technical solution: a motor-embedded integrated electric winch, comprising a motor bracket, the motor bracket being fixedly connected to the tail end of a drive motor, the head end of the drive motor being provided with a transfer plate fixedly connected thereto, the transfer plate being fixedly connected to the inner wall of a drum via a bearing; the motor shaft on the drive motor passes through the transfer plate and is connected to a reducer assembly; the reducer assembly includes a primary driven wheel meshing with the motor shaft and a fourth-stage driving wheel meshing with an internal gear ring on the drum, the drive motor driving the primary driven wheel to rotate while the fourth-stage driving wheel drives the drum to rotate.
[0005] Preferably, the reducer assembly includes a housing and a mounting base. The mounting base houses a four-stage driving wheel and a three-stage driven wheel. The drive shaft on the four-stage driving wheel meshes with the three-stage driven wheel. The four-stage driving wheel meshes with the internal gear ring of the drum. The housing is equipped with a clutch assembly for keeping the drive shaft on the four-stage driving wheel disengaged or engaged with the three-stage driven wheel. The three-stage driven wheel is mounted on the drive shaft of the four-stage driving wheel, and the clutch assembly drives the three-stage driven wheel to move on the drive shaft of the four-stage driving wheel.
[0006] The reducer assembly is equipped with a clutch assembly for controlling the engagement or disengagement of the drive shaft on the fourth-stage drive wheel and the third-stage driven wheel. The clutch assembly allows for convenient control of the gear engagement state of the entire reducer assembly. When the drive shaft on the fourth-stage drive wheel is engaged with the third-stage driven wheel, the reducer assembly can drive the drum to rotate. When the drive shaft on the fourth-stage drive wheel is disengaged from the third-stage driven wheel, the reducer assembly will not drive the drum to rotate, and the drive motor will be in an idling state.
[0007] Preferably, the clutch assembly includes a clutch spring and a clutch ring. The clutch ring is sleeved on the drive shaft of the fourth-stage drive wheel and connected to the third-stage driven wheel via a bearing. The clutch spring is also sleeved on the drive shaft of the fourth-stage drive wheel, with one end resting against the clutch ring and the other end resting against the housing. When the clutch spring compresses the clutch ring, the third-stage driven wheel moves closer to the fourth-stage drive wheel.
[0008] When the clutch assembly is in the open state, the clutch spring will be further compressed from its initial compressed state, so that the drive shaft on the third-stage driven wheel and the fourth-stage driving wheel are always disengaged. When the clutch assembly is in the closed state, the clutch spring will continuously engage the clutch ring, which, together with the third-stage driven wheel, will press against the drive shaft on the fourth-stage driving wheel. During the rotation of the third-stage driven wheel, as long as it is fully aligned with the teeth on the drive shaft on the fourth-stage driving wheel, the third-stage driven wheel will automatically engage with the drive shaft on the fourth-stage driving wheel under the action of the clutch spring. In this way, the clutch assembly facilitates the meshing of the teeth between the third-stage driven wheel and the drive shaft on the fourth-stage driving wheel.
[0009] Preferably, the clutch assembly further includes a clutch handle and a clutch shaft; the clutch handle and the clutch shaft are fixedly connected, the clutch ring is provided with a limiting groove, and the lower end face of the clutch shaft is provided with a limiting protrusion at an eccentric position. The limiting protrusion is stuck in the limiting groove. When the clutch shaft rotates, it drives the limiting protrusion to push the clutch ring to move. The clutch ring is connected to the three-stage driven wheel through a bearing.
[0010] The third-stage driven wheel is connected to the clutch ring via a bearing. When the clutch handle is rotated, the limiting protrusion on the clutch shaft rotates. As the limiting protrusion rotates, it pushes the side wall on the limiting groove, thereby causing the clutch ring to move relative to the drive shaft on the fourth-stage driving wheel. As the clutch ring moves, it keeps the third-stage driven wheel and the drive shaft on the fourth-stage driving wheel engaged or disengaged. Therefore, when the clutch assembly is opened or closed, it ensures that the third-stage driven wheel and the drive shaft on the fourth-stage driving wheel are engaged or disengaged, improving the reliability of the clutch assembly.
[0011] Preferably, the motor shaft passes through the interior of the adapter plate and is connected to the inner wall of the adapter plate via a bearing.
[0012] The motor shaft is connected to the adapter plate via bearings, and the adapter plate is connected to the roller via bearings. This ensures that the motor shaft remains stable during rotation and does not deviate axially from the roller, greatly improving the stability of the drive motor's rotation and thus increasing the transmission efficiency of the drive motor.
[0013] Preferably, the drive motor includes a motor tail cover, which is fixed on the motor bracket, and the end face of the motor tail cover is provided with an electrical control box for controlling the rotation of the drive motor.
[0014] The motor tail cover is fixed to the motor bracket, so that the drive motor and the motor bracket will maintain a stable connection, and the drive motor will remain stable during rotation. The electrical control box is directly installed on the end face of the motor tail cover, which greatly shortens the distance between the electrical control box and the drive motor, thus shortening the overall length of the winch.
[0015] Preferably, the reducer assembly includes a mounting base, a first-stage driven wheel, a second-stage driving wheel, a second-stage driven wheel, a third-stage driving wheel, a third-stage driven wheel, and a fourth-stage driving wheel; all four stages are mounted on the mounting base; the first-stage driven wheel meshes with the motor shaft, and its rotation simultaneously drives the second-stage driving wheel; the second-stage driving wheel meshes with the second-stage driven wheel, and its rotation simultaneously drives the third-stage driving wheel; the third-stage driving wheel meshes with the third-stage driven wheel, and its rotation simultaneously drives the transmission shaft on the fourth-stage driving wheel; the transmission shaft on the fourth-stage driving wheel rotates synchronously with the fourth-stage driving wheel, and its rotation simultaneously drives the drum to rotate.
[0016] The gears on the reducer assembly are directly connected to the motor shaft, so that when the motor shaft rotates, it can directly drive all the gears on the reducer assembly to rotate simultaneously, which greatly improves the transmission efficiency of the drive motor.
[0017] Preferably, the secondary driven wheel is provided with a manual wheel that is fixedly connected to it. The manual wheel is connected to the housing through a bearing and extends out of the housing. The manual wheel is provided with an inlet for inserting an external handle.
[0018] The secondary driven wheel is fixedly connected to the manual wheel. When the drive motor is not working, an external handle is inserted into the inlet, and rotating the external handle simultaneously drives the secondary driven wheel to rotate. The rotation of the secondary driven wheel drives all the gears on the reducer assembly, which in turn drives the drum to rotate, facilitating winch operation in power-off environments. Because the secondary driven wheel has a larger diameter, its angular velocity is lower for the same linear velocity. This means the external handle does not need to be rotated quickly to drive the drum, reducing the number of rotations per unit time and optimizing manual operation.
[0019] Preferably, the fourth-stage drive wheel meshes with the internal gear ring on the drum, and the fourth-stage drive wheel is connected to the mounting base through the first bearing.
[0020] The fourth-stage driving wheel is connected to the mounting base via the first bearing. The fourth-stage driving wheel rotates when the third-stage driven wheel rotates. At the same time, the fourth-stage driving wheel rotates relative to the mounting base and drives the internal gear ring of the roller to rotate. This planetary gear transmission method allows the roller to generate greater torque, making it easier to pull heavier items.
[0021] Compared with existing technologies, the present invention has the following advantages: The present invention fixes the tail end of the drive motor to the motor bracket and inserts the head of the drive motor into the drum and fixes it to the inner wall of the drum via bearings. This allows the drive motor to be stably installed inside the drum, significantly shortening the overall length of the winch and providing more installation positions. Simultaneously, the drive motor is embedded inside the drum, bringing the motor shaft closer to the reducer assembly. The motor shaft is directly connected to the reducer assembly, reducing energy loss during motor rotation and greatly improving the transmission efficiency of the drive motor. Therefore, the present invention significantly improves the transmission efficiency of the motor while shortening the winch size, resulting in good practical performance. Attached Figure Description

[0030] The present invention will be further described below with reference to the embodiments illustrated in the accompanying drawings:
[0031] like Figures 1 to 7 As shown, this invention discloses a motor-embedded integrated electric winch, including a motor bracket 1, which is fixedly connected to the tail of a drive motor 2. The head of the drive motor 2 is provided with a transfer plate 3 fixedly connected to it, and the transfer plate 3 is fixedly connected to the inner wall of a drum 4 through a bearing. The motor shaft 21 on the drive motor 2 passes through the transfer plate 3 and is connected to a reducer assembly 5. The reducer assembly 5 includes a primary driven wheel 51 that meshes with the motor shaft 21 and a fourth-stage driving wheel 52 that meshes with the internal gear ring on the drum 4. When the drive motor 2 drives the primary driven wheel 51 to rotate, the fourth-stage driving wheel 52 drives the drum 4 to rotate.
[0032] The reducer assembly 5 includes a housing 53 and a mounting base 54. The mounting base 54 is provided with a four-stage driving wheel 52 and a three-stage driven wheel 55. The drive shaft on the four-stage driving wheel 52 meshes with the three-stage driven wheel 55. The four-stage driving wheel 52 meshes with the internal gear ring of the roller 4. The housing 53 is provided with a clutch assembly 6 for keeping the drive shaft on the four-stage driving wheel 52 in a disengaged or engaged state with the three-stage driven wheel 55. The three-stage driven wheel 55 is sleeved on the drive shaft of the four-stage driving wheel 52. The clutch assembly 6 drives the three-stage driven wheel 55 to move on the drive shaft of the four-stage driving wheel 52. The clutch assembly 6 includes a clutch spring 61 and a clutch ring 64. The clutch ring 64 is sleeved on the drive shaft of the fourth-stage drive wheel 52 and connected to the third-stage driven wheel 55 via a bearing. The clutch spring 64 is also sleeved on the drive shaft of the fourth-stage drive wheel 52. One end of the clutch spring 61 rests against the clutch ring 64, and the other end rests against the housing 53. While the clutch spring 61 compresses the clutch ring 64, the third-stage driven wheel 55 moves closer to the fourth-stage drive wheel 52. The clutch assembly 6 further includes a clutch handle 62 and a clutch shaft 63; the clutch handle 62 and clutch shaft 63 are fixedly connected, the clutch ring 64 is provided with a limiting groove 65, and the lower end face of the clutch shaft 63 is provided with a limiting protrusion 66 at an eccentric position. The limiting protrusion 66 is engaged in the limiting groove 66. When the clutch shaft 63 rotates, it drives the limiting protrusion 66 to push the clutch ring 64 to move. The clutch ring 64 is connected to the three-stage driven wheel 55 through a bearing. The motor shaft 21 passes through the interior of the adapter plate 3 and is connected to the inner wall of the adapter plate 3 through a bearing. The drive motor 2 includes a motor tail cover 22, which is fixed on the motor bracket 1. The end face of the motor tail cover 22 is provided with an electrical control box 7 for controlling the rotation of the drive motor 2. The reducer assembly 5 includes a mounting base 54, a first-stage driven wheel 51, a second-stage driving wheel 57, a second-stage driven wheel 58, a third-stage driving wheel 59, a third-stage driven wheel 55, and a fourth-stage driving wheel 52. All four wheels are mounted on the mounting base 54. The first-stage driven wheel 51 meshes with the motor shaft 21. Rotation of the first-stage driven wheel 51 simultaneously drives the second-stage driving wheel 57 to rotate. The second-stage driving wheel 57 meshes with the second-stage driven wheel 58. Rotation of the second-stage driven wheel 58 simultaneously drives the third-stage driving wheel 59 to rotate. The third-stage driving wheel 59 meshes with the third-stage driven wheel 55. Rotation of the third-stage driven wheel 55 simultaneously drives the transmission shaft on the fourth-stage driving wheel 52 to rotate. The transmission shaft on the fourth-stage driving wheel 52 rotates synchronously with the fourth-stage driving wheel 52. Rotation of the fourth-stage driving wheel 52 simultaneously drives the roller 4 to rotate.The secondary driven wheel 58 is equipped with a manual wheel 8 fixedly connected to it. The manual wheel 8 is connected to the housing 53 via a bearing and extends out of the housing 53. The manual wheel 8 is provided with an inlet 81 for inserting an external handle. The fourth-stage driving wheel 52 meshes with the internal gear ring on the roller 4. The fourth-stage driving wheel 52 is connected to the mounting base 54 via a first bearing 9.
[0033] The specific working process of this invention is as follows: When the winch needs to be in an idling state, the clutch handle 62 is turned, and the clutch shaft 63 rotates with the clutch handle 62. The limiting protrusion 66 at the end of the clutch shaft 63 moves in the limiting groove 65 and drives the clutch ring 64 to approach the housing 53. The clutch ring 64 is fixedly connected to the third-stage driven wheel 55 through a bearing. The third-stage driven wheel 55 also approaches the housing 53 with the clutch ring 64. During the movement, the third-stage driven wheel 55 will disengage from the drive shaft of the fourth-stage driving wheel 52. Thus, when the drive motor 2 rotates, it cannot drive the fourth-stage driving wheel 52 to rotate. The fourth-stage driving wheel 52 cannot drive the drum 4 to rotate, and the drive motor 2 will be in an idling state. At this time, the clutch assembly 6 is in a disengaged state.
[0034] When the winch needs traction, the clutch handle 62 is rotated. During rotation, the limiting protrusion 66 on the clutch shaft 63 pushes against the side wall of the limiting groove 65. The clutch ring 63, being pushed, moves closer to the fourth-stage drive wheel 52. Because a clutch spring 61 is provided between the clutch ring 63 and the first bearing 9, the clutch spring 61 is always compressed and provides elasticity to the clutch ring 63. In this way, the clutch ring 63 and the third-stage driven wheel 55 will always compress the drive shaft on the fourth-stage drive wheel 52. When the third-stage driven wheel 55 rotates a certain angle, it will automatically engage with the drive shaft on the fourth-stage drive wheel 52. When the three-stage driven wheel 55 rotates, it synchronously drives the four-stage driving wheel 52 to rotate. When the drive motor 2 rotates, the motor shaft 21 drives the first-stage driven wheel 51 to rotate. The first-stage driven wheel 51 rotates simultaneously with the second-stage driving wheel 57. The second-stage driving wheel 57 rotates simultaneously with the second-stage driven wheel 58. The second-stage driven wheel 58 rotates simultaneously with the third-stage driving wheel 59. The third-stage driving wheel 59 rotates simultaneously with the third-stage driven wheel 55. The third-stage driven wheel 55 rotates simultaneously with the fourth-stage driving wheel 52. The fourth-stage driving wheel 52 rotates simultaneously with the roller 4.
[0035] The secondary driven wheel 58 is provided with a manual wheel 8 fixedly connected to it, and the manual wheel 81 is provided with an inlet 81 for inserting an external handle; when the drive motor 2 cannot rotate in the power-off state, the handle wheel 8 is driven to rotate by the external handle, so that the secondary driven wheel 58 will drive all the gears on the reducer assembly 5 to rotate, so that the reducer assembly 5 will drive the roller 4 to rotate.
[0036] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
