Abstract
Description
Technical Field
[0001] This utility model relates to the field of clutch drive technology, and in particular to a two-way clutch. Background Technology
[0002] The clutch, a crucial mechanical transmission device, plays a vital role in mechanical systems. Its primary function is to connect and disconnect a power source (such as an engine or electric motor) from a driven device (such as a transmission or working mechanism). During power transmission, the clutch can smoothly engage or disengage as needed, controlling the transmission and interruption of power. When engaged, the clutch ensures that the torque generated by the power source is effectively transmitted to the driven device, driving the mechanical equipment to operate normally. When power transmission needs to be interrupted, the clutch can quickly and smoothly disengage, avoiding impact and damage to the mechanical equipment. The clutch also has overload protection. When the mechanical equipment encounters excessive resistance or torque during operation, the clutch can automatically slip, protecting the equipment from damage. Existing clutches have relatively complex structures and poor stability during power transmission, affecting their transmission performance. Therefore, improvements are needed to the existing clutch structure for power transmission. Utility Model Content
[0003] To address the aforementioned problems, this invention achieves bidirectional transmission, precise positioning, and high efficiency and stability through ingenious structural design and innovative transmission methods. This bidirectional clutch enhances the overall performance of the clutch.
[0004] The technical solution adopted by this utility model is as follows: a bidirectional clutch, including a housing, a connecting member, a transmission member, and a limiting member. The housing is provided with a cavity, and a connecting hole is provided on one side of the housing. The wall of the cavity is provided with multiple positioning grooves. The connecting member is disposed in the cavity and is provided with a connecting part, one end of which extends into the positioning groove. The transmission member is disposed in the cavity and is provided with a driving groove, which is opposite to the positioning groove. The limiting member is disposed between the driving groove and the positioning groove. Push blocks are provided on both sides of the driving groove. When the transmission member rotates in the cavity, the pushing blocks push the limiting member toward the positioning groove and place it into the positioning groove for positioning, so as to drive the housing to rotate through the pushing blocks.
[0005] A further improvement to the above solution is that multiple positioning grooves are evenly distributed in a circumferential direction on the wall of the cavity, and guide arc surfaces are provided on both sides of the positioning grooves. The guide arc surfaces are used to guide the limiting member toward the positioning groove.
[0006] A further improvement to the above scheme is that the number of positioning grooves is twice the number of driving grooves.
[0007] A further improvement to the above solution is that the connector is provided with a connecting plate, the connecting plate is disposed in the cavity, and the connecting part is disposed on the connecting plate.
[0008] A further improvement to the above solution is that the connecting part is provided with a mating hole, and the mating hole is provided with a mating groove.
[0009] A further improvement to the above solution is that the transmission component is provided with a drive mounting hole, and the drive mounting hole is coaxial with the docking hole.
[0010] A further improvement to the above solution is that the transmission component includes an outer disk body and a drive disk, the drive disk is disposed on one side of the outer disk body, and the drive groove is disposed on the outer periphery of the drive disk.
[0011] A further improvement to the above scheme is that the drive disk includes an inner disk body and a drive outer ring. The outer periphery of the inner disk body is provided with a mating tooth block, and the inner periphery of the drive outer ring is provided with a mating tooth groove, which is used to engage the mating tooth block. The drive groove is provided on the outer periphery of the drive outer ring.
[0012] A further improvement to the above solution is that guide slopes are provided on both sides of the driving groove, and the guide slopes are used to guide the limiting member toward the positioning groove.
[0013] A further improvement to the above solution is that the two ends of the limiting member are chamfered.
[0014] The beneficial effects of this utility model are:
[0015] Compared to existing clutches, this invention provides a solid foundation for the precise fit between the connecting and transmission components by incorporating a cavity and positioning groove within the outer casing. The connecting portion on the connecting component extends precisely into the positioning groove. This structure not only enhances the overall stability of the clutch but also ensures reliable connections between components, effectively preventing functional failures caused by loosening or misalignment. Secondly, the drive groove on the transmission component is arranged opposite to the positioning groove, utilizing spatial layout, with the limiting component positioned between them. This simplifies the internal structure of the clutch and improves its transmission efficiency. When the transmission component rotates within the cavity, the pusher blocks function, pushing the limiting component towards and positioning it within the positioning groove. This process not only achieves the bidirectional transmission function of the clutch but also ensures the accuracy and stability of the transmission. Furthermore, the design of the pusher blocks is a major highlight of this solution. They not only drive the movement of the limiting component but also indirectly drive the rotation of the outer casing through the cooperation between the limiting component and the positioning groove. This not only enhances the clutch's transmission capacity but also makes it more flexible and adaptable to more complex working conditions in practical applications. This invention, through its ingenious structural design and innovative transmission method, achieves bidirectional transmission, precise positioning, and high efficiency and stability in the clutch, thereby improving the overall performance of the clutch.

Detailed Implementation
[0025] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.
[0026] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.
[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Figures 1-8As shown, in one embodiment of this utility model, a bidirectional clutch is disclosed, comprising a housing 1, a connecting member 2, a transmission member 3, and a limiting member 4. The housing 1 has a cavity 11, and a connecting hole 12 is provided on one side of the housing 1. The wall surface of the cavity 11 is provided with multiple positioning grooves 13. The connecting member 2 is disposed in the cavity 11 and has a connecting portion 21, one end of which extends into the positioning groove 13. The transmission member 3 is disposed in the cavity 11 and has a driving groove 31, which is opposite to the positioning groove 13. The limiting member 4 is disposed between the driving groove 31 and the positioning groove 13. Push blocks 32 are provided on both sides of the driving groove 31. When the transmission member 3 rotates in the cavity 11, the pushing blocks 32 push the limiting member 4 toward the positioning groove 13 and place it into the positioning groove 13 for positioning, thereby driving the housing 1 to rotate. This embodiment provides a solid foundation for the precise cooperation between the connecting member 2 and the transmission member 3 by setting the cavity 11 and the positioning groove 13 inside the housing 1. The connecting portion 21 on the connector 2 extends precisely into the positioning groove 13. This structure not only enhances the overall stability of the clutch but also ensures reliable connection between various components, effectively preventing functional failure due to loosening or misalignment. Secondly, the drive groove 31 on the transmission component 3 is arranged opposite to the positioning groove 13, utilizing spatial layout, with the limiting component 4 positioned between them. This simplifies the internal structure of the clutch and improves its transmission efficiency. When the transmission component 3 rotates within the cavity 11, the push block 32 functions, pushing the limiting component 4 towards the positioning groove 13 and positioning it therein. This process not only realizes the bidirectional transmission function of the clutch but also ensures the accuracy and stability of the transmission. Furthermore, the design of the push block 32 is a major highlight of this solution. It not only drives the movement of the limiting component 4 but also indirectly drives the rotation of the outer casing 1 through the cooperation of the limiting component 4 and the positioning groove 13. This not only enhances the transmission capacity of the clutch but also makes it more flexible and adaptable in practical applications, meeting the needs of more complex working conditions. This embodiment achieves bidirectional transmission, precise positioning, and high efficiency and stability of the clutch through ingenious structural design and innovative transmission method, thereby improving the overall performance of the clutch. In the above embodiment, the limiting member 4 is a limiting pin, and the depth of the positioning groove 13 is less than the outer diameter of the limiting pin. When the push block 32 rotates, it abuts against the outer diameter of the limiting pin, thereby pushing the outer shell 1 to rotate.
[0028] Multiple positioning grooves 13 are evenly distributed circumferentially on the wall of the cavity 11. Guide arc surfaces 131 are provided on both sides of each positioning groove 13, guiding the limiting member 4 towards the positioning groove 13. Specifically, the number of positioning grooves 13 is twice the number of driving grooves 31. In this embodiment, it is ensured that the limiting member 4 can accurately enter the positioning groove 13. The design of the guide arc surfaces 131 cleverly guides the limiting member 4 to move along a predetermined path, reducing errors during assembly and improving the overall assembly accuracy of the clutch. Secondly, the number of positioning grooves 13 is set to be twice the number of driving grooves 31. This design not only enhances the stability of the clutch structure but also improves its transmission efficiency. When the clutch is working, more positioning grooves 13 mean more contact points, which helps to distribute stress, reduce wear on individual components, and thus extend the service life of the clutch.
[0029] The connecting member 2 is provided with a connecting plate 22, which is disposed within the cavity 11, and the connecting part 21 is disposed on the connecting plate 22. Specifically, the connecting part 21 is provided with a mating hole 211, and a mating groove 212 is provided on the mating hole 211. The mating hole 211 is used for connecting an externally mounted connecting shaft, and the mating groove 212 is used to fix the connecting shaft to the connecting part 21 to achieve a limiting position. The transmission member 3 is provided with a drive mounting hole 33, which is coaxial with the mating hole 211. In this embodiment, the connecting plate 22 on the connecting member 2 is cleverly embedded within the clutch cavity 11, which not only optimizes the spatial layout but also ensures the compactness and stability of the structure. As an intermediary, the connecting plate 22 effectively connects the connecting part 21 to the clutch body, laying a solid foundation for the smooth transmission of power. The carefully designed mating hole 211 and mating groove 212 of the connecting part 21 demonstrate high manufacturing precision and ease of assembly. The mating hole 211 is coaxially arranged with the drive mounting hole 33 on the transmission component 3, ensuring accurate power transmission and reducing energy loss and component wear caused by misalignment. At the same time, the introduction of the mating groove 212 further improves the connection stability and reliability between the connecting part 21 and the transmission component 3, effectively preventing loosening or detachment caused by vibration or load changes.
[0030] The transmission component 3 includes an outer disk body 34 and a drive disk 35. The drive disk 35 is disposed on one side of the outer disk body 34, and a drive groove 31 is disposed on the outer periphery of the drive disk 35. Specifically, the drive disk 35 includes an inner disk body 351 and a drive outer ring 352. The inner disk body 351 is connected to the outer disk body 34. The outer periphery of the inner disk body 351 is provided with a mating tooth block 3511, and the inner periphery of the drive outer ring 352 is provided with a mating tooth groove 3521 for meshing with the mating tooth block 3511. The drive groove 3521 is disposed on the outer periphery of the drive outer ring 352. In this embodiment, the transmission component 3 is mainly composed of an outer disk body 34, a drive disk 35, and a drive groove 31 thereon. The drive disk 35 is further subdivided into an inner disk body 351 and a drive outer ring 352. Through the precise meshing of the mating tooth block 3511 and the mating tooth groove 3521, the structural stability and transmission accuracy are achieved. During the operation of the two-way clutch, the drive groove 31 on the drive outer ring 352 can effectively cooperate with the corresponding components in the clutch to realize the transmission and conversion of power. Due to the design of the mating tooth block 3511 and the mating tooth groove 3521, the connection between the inner and outer parts of the drive disc 35 is tighter, reducing transmission errors caused by loosening or wear, thereby improving the transmission accuracy and reliability of the clutch. In addition, this structure also enhances the durability of the transmission component 3. The meshing of the mating tooth block 3511 and the mating tooth groove 3521 not only provides stable support, but also disperses the stress during clutch operation to a certain extent, reducing component damage caused by long-term high-load operation.
[0031] Guide ramps 311 are provided on both sides of the drive groove 31, which guide the limiting member 4 toward the positioning groove 13. In this embodiment, the guide ramps 311 can accurately guide the limiting member 4 to the positioning groove 13, ensuring smoothness and precision of the clutch during engagement and disengagement. This design reduces frictional losses caused by misalignment or jamming of the limiting member 4, thereby extending the service life of the clutch. In addition, the application of the guide ramps 311 also enhances the clutch's self-adaptability. When faced with different operating conditions or load changes, the clutch can quickly adjust and maintain a stable working state, effectively avoiding malfunctions caused by instability in the transmission system.
[0032] The limiting member 4 has chamfers 41 at both ends. In this embodiment, the chamfers 41 are designed to facilitate assembly of the structure, reduce friction, and improve transmission stability.
[0033] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
