Description

Technical Field

[0001] This application belongs to the field of air compressor technology, specifically relating to a clutch air compressor. Background Technology

[0002] The number of power take-off points in existing vehicles is limited by the engine structure design. Vehicles require numerous driven components, including at least an air compressor, steering hydraulic pump, air conditioning compressor, and urea injection pump, all of which rely on the engine's power take-off points. Therefore, existing vehicle engines cannot meet the independent power needs of multiple driven components. Since the steering hydraulic pump is a core component ensuring vehicle steering function, given the limited number of engine power take-off points, the vehicle needs to integrate the power input of the steering hydraulic pump into the air compressor's power take-off point. Therefore, the vehicle's steering hydraulic pump can only be installed on the air compressor's power take-off point. However, the crankshaft of existing clutch-operated air compressors cannot rotate continuously. When the clutch is disengaged, the crankshaft stops rotating, failing to drive the steering hydraulic pump. The steering hydraulic pump requires a continuous power supply to ensure the steering system's responsiveness. Existing clutch-operated air compressors cannot continuously provide power to the steering hydraulic pump; the power to the steering hydraulic pump is interrupted due to the clutch operation of the air compressor. Therefore, existing clutch-operated air compressors are unsuitable for continuously driven components such as the steering hydraulic pump. Utility Model Content

[0003] This application provides a clutch-operated air compressor to solve the technical problem that existing clutch-operated air compressors cannot continuously provide power to the driven components.

[0004] The technical solution adopted in this application is as follows: A clutch-operated air compressor includes an air compression section and a power output section. The air compression section includes a drive component, a compression actuator shaft, and a clutch device. The power output section is located radially outside the compression actuator shaft. The drive component is driven to the compression actuator shaft via the clutch device. The drive component is also driven to the power output section. The clutch device has a transmission state connected to the drive component and a disengagement state disconnected from the drive component. In both the transmission and disengagement states, the drive component can continuously transmit power to the power output section.

[0005] The clutch-type air compressor in this application also includes the following additional technical features: The power output unit includes a driven member, a mounting member, and an output shaft rotatably mounted on the mounting member. The output shaft is connected to the driven member, and the driving member is connected to the driven member in a transmission manner. The air compression unit also includes a main body and a receiving cavity disposed in the main body. The mounting member and the main body are integrally formed.

[0006] The cavity contains a compression component. The rotation of the compression actuation shaft drives the compression component to move up and down. The mounting component is located on the side of the compression actuation shaft away from the compression component.

[0007] The compression actuator includes an execution section that drives the compression component to move and an installation section connected to the execution section. The drive component and clutch device are arranged sequentially along the axial direction of the installation section.

[0008] The drive component is rotatably mounted on the compression actuator shaft. The clutch device includes a housing rotatably mounted on the compression actuator shaft. The housing is movably mounted on the compression actuator shaft. The drive component is drive-connected to the housing. The housing is drive-connected to the compression actuator shaft. The clutch air compressor also includes a pusher component that can drive the housing to move so that the housing is drive-connected to or disengaged from the drive component.

[0009] The housing has a mounting cavity, the drive unit is connected to the rotating unit, the rotating unit is rotatably mounted on the compression actuator shaft, the inner wall of the mounting cavity is provided with a friction element, the friction element is in contact with the rotating unit, and the drive unit drives the housing to rotate.

[0010] The clutch air compressor also includes a fixing component that is fixedly connected to the compression actuator shaft. The fixing component is located in the mounting cavity and has multiple guide grooves. The inner wall of the mounting cavity has guide protrusions that cooperate with the guide grooves.

[0011] An elastic reset element is provided between the fixing component and the housing, which can drive the housing to reset.

[0012] The housing is connected to the movable component via an elastic reset component. The movable component has a movable hole. The fixed component has a protrusion extending toward the side opposite to the driving component. One of the movable hole and the protrusion has a movable protrusion, and the other has a movable groove. The pushing component is used to drive the movable component to move.

[0013] The pushing component includes a telescopic component that drives the moving component to move and an air supply assembly for driving the telescopic component to extend and retract. The air compression unit includes a main body and a receiving cavity disposed in the main body, and the air supply assembly is disposed on the inner wall of the receiving cavity.

[0014] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows: 1. This application addresses the issue of the power output unit's continuous power transmission to the drive unit whether the clutch is in a driving or disengaged state, ensuring a constant power supply. Even when the clutch is disengaged and the compressor shaft stops rotating, the power output unit maintains a stable power output, ensuring continuous operation of the driven components and preventing power interruption due to clutch engagement / disengagement. By controlling the operation of the compressor shaft through the clutch, power transmission is cut off when compressed air is not needed, reducing energy consumption. By positioning the power output unit radially outside the compressor shaft, radial space is fully utilized, avoiding excessive increases in the axial dimension of the clutch compressor and enabling integrated installation of the vehicle's powertrain.

[0015] 2. As a preferred embodiment of this application, by setting the driving component and the driven component to maintain a meshing state, the driving component can continuously drive the driven component to rotate, providing continuous power to the output shaft. By setting the mounting component to be integrally formed with the main body, the stability and rigidity of the overall structure are improved. The connection gap and assembly error between the mounting component and the main body are eliminated, and the mounting component can more stably support the rotation of the output shaft, reducing component wear caused by vibration or uneven force, and extending the service life of the equipment. At the same time, it can simplify the production and assembly process, eliminating the need to separately manufacture the mounting component and perform subsequent connection and assembly processes, reducing the number of parts and assembly complexity, and helping to improve production efficiency and reduce manufacturing costs. The integral molding design makes the structure of the mounting component and the main body more compact, and the cooperation with other structures such as the receiving cavity is more coordinated, further saving the overall space of the equipment and better adapting to the compact layout requirements of the vehicle power system.

[0016] Furthermore, by placing the mounting component on the side of the compression actuator shaft away from the compressor, the working parts connected to the output shaft are axially distributed with the compressor, avoiding structural interference and achieving a compact design for the clutch air compressor, thus providing operational convenience for subsequent maintenance and component replacement.

[0017] Furthermore, by setting the compression actuator shaft to include an execution section and an installation section, the functional partitioning of the compression actuator shaft is achieved. The execution section directly drives the compression component to complete the compression action, ensuring direct power transmission; the installation section carries the drive component and clutch device, making power input and clutch control independent modules. At the same time, by setting the drive component and clutch device sequentially along the axial direction of the installation section, the radial dimension increase caused by radial stacking is avoided, making the structure of the clutch air compressor more compact and facilitating the installation of the clutch air compressor.

[0018] 3. In a preferred embodiment of this application, a drive member is rotatably mounted on the compression actuator shaft. In the disengaged state, the drive member can rotate around the compression actuator shaft. The housing of the clutch device can both rotate around the compression actuator shaft and be movably mounted on the compression actuator shaft. The housing is moved by a pusher member, enabling the housing to connect or disconnect from the drive member. When the housing is connected to the drive member, the power of the drive member can be efficiently transmitted to the compression actuator shaft for compression. When the housing disconnects from the drive member, the power can be quickly cut off, preventing the compression actuator shaft from running continuously and improving the energy consumption control capability of the clutch air compressor.

[0019] Furthermore, by setting friction elements on the inner wall of the mounting cavity of the housing, the rotating component connected to the drive component can be engaged or disengaged from the friction elements through the axial movement of the housing. When the rotating component is engaged with the friction elements, the power of the drive component can be efficiently transmitted to the housing through friction transmission, thereby driving the compression actuator to move. The friction engagement method can reduce the impact of rigid connection and make the power transmission smoother.

[0020] 4. As a preferred embodiment of this application, by providing a fixing member, the fixing member cooperates with the guide protrusion on the inner wall of the housing mounting cavity through the guide groove. When the guide protrusion of the housing moves along the guide groove, it can ensure that the fixing member and the housing rotate synchronously, thereby improving the stability of power transmission.

[0021] Furthermore, by incorporating an elastic reset component, the housing can automatically reset itself using its own elastic potential energy after the pushing component stops driving. This allows the friction component to engage with the rotating component, enabling the driving component to rotate the housing. The reset action can be completed without additional power input, simplifying the control process and improving the equipment's response speed to changes in operating conditions. Simultaneously, the continuous preload of the elastic reset component reduces axial movement of the housing during transmission, resulting in a tighter fit between the guide protrusion and the guide groove, enhancing the continuity of power transmission.

[0022] 5. In a preferred embodiment of this application, a pushing member is provided to drive the moving member to move. The moving protrusion can slide smoothly along the moving groove, driving the housing to move synchronously, making the clutch switching process smoother. By providing the moving member, the moving member provides a stable abutment part for the pushing member, so that the driving force of the pushing member can be directly and concentrated on the moving member, improving driving efficiency.

[0023] Furthermore, by placing the air supply components on the inner wall of the housing cavity, the internal space of the housing cavity is fully utilized, eliminating the need for additional installation space and making the overall structure of the clutch air compressor more compact.

[0026] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0031] like Figure 1 , Figure 2 , Figure 3 As shown, a clutch-type air compressor includes an air compression unit 1 and a power output unit 2. The air compression unit 1 includes a drive member 11, a compression actuation shaft 12, and a clutch device 13. The power output unit 2 is located radially outside the compression actuation shaft 12. The drive member 11 is connected to the compression actuation shaft 12 via the clutch device 13. The drive member 11 is also connected to the power output unit 2. The clutch device 13 has a transmission state connected to the drive member 11 and a disengagement state disconnected from the drive member 11. In both the transmission and disengagement states, the drive member 11 can continuously transmit power to the power output unit 2.

[0032] This application ensures that the drive unit 11 continuously transmits power to the power output unit 2 whether the clutch device 13 is in the driving or disengaged state, allowing the power output unit 2 to continuously receive power. Even when the clutch device 13 is disengaged and the compression actuator 12 stops rotating, the power output unit 2 can still stably output power, ensuring the continuous operation of the driven components and avoiding power interruption caused by the clutch operation of the air compressor. By controlling the operation of the compression actuator 12 through the clutch device 13, power transmission is cut off when compressed air is not needed, thereby reducing energy consumption. By placing the power output unit 2 radially outside the compression actuator 12, radial space is fully utilized, avoiding excessive increase in the axial dimension of the clutch air compressor and achieving integrated installation of the vehicle power system.

[0033] In this application, the connection method between the mounting component 22 and the main body 14 can be any of the following embodiments: Implementation method one: such as Figure 1 , Figure 2 , Figure 3As shown, the power output unit 2 includes a driven member 21, a mounting member 22, and an output shaft 23 rotatably mounted on the mounting member 22. The output shaft 23 is connected to the driven member 21, and the driving member 11 is drive-connected to the driven member 21. The air compression unit 1 also includes a main body 14 and a receiving cavity 15 disposed in the main body 14. The mounting member 22 is integrally formed with the main body 14. Preferably, the driving member 11 is a drive gear, and the driven member 21 is a driven gear. The driving member 11 meshes with the driven member 21, and the driving member 11 is drive-connected to the vehicle's engine. Those skilled in the art will understand that the drive member 11 and the driven member 21 can be driven by meshing, by a transmission chain, or by a synchronous belt, etc. This application does not limit the connection. The driving member 11 can be driven by an electric motor or drive-connected to the vehicle's engine, etc.

[0034] By maintaining the engagement between the driving component 11 and the driven component 21, the driving component 11 can continuously drive the driven component 21 to rotate, providing continuous power to the output shaft 23. The integral molding of the mounting component 22 with the main body 14 improves the stability and rigidity of the overall structure. Eliminating the connection gap and assembly error between the mounting component 22 and the main body 14, the mounting component 22 can more stably support the rotation of the output shaft 23, reducing component wear caused by vibration or uneven stress, and extending the service life of the equipment. Simultaneously, it simplifies the production and assembly process, eliminating the need to separately manufacture the mounting component 22 and perform subsequent connection and assembly processes, reducing the number of parts and assembly complexity, and helping to improve production efficiency and reduce manufacturing costs. The integral molding design allows for a more compact structure of the mounting component 22 and the main body 14, and better coordination with other structures such as the receiving cavity 15, further saving overall equipment space and better adapting to the compact layout requirements of the vehicle's powertrain system.

[0035] Implementation Method 2: Unlike Implementation Method 1, the mounting component 22 is detachably connected to the main body 14.

[0036] In embodiment one, the mounting component 22 can be installed in any of the following embodiments: Example 1: As Figure 2 As shown, a compression component 16 is provided in the receiving cavity 15. The compression actuation shaft 12 rotates to drive the compression component 16 to compress up and down. The mounting component 22 is located on the side of the compression actuation shaft 12 away from the compression component 16.

[0037] By setting the mounting component 22 on the side of the compression actuator 12 away from the compressor component 16, the working parts connected to the output shaft 23 are axially distributed with the compressor component 16, avoiding structural interference, realizing a compact design of the clutch air compressor, and providing operational convenience for subsequent maintenance and component replacement.

[0038] Example 2: As shown in the figure, the cavity 15 is provided with a compression component 16. The compression execution shaft 12 rotates to drive the compression component 16 to compress up and down. Along the circumference of the main body 14, the mounting component 22 and the compression component 16 are spaced apart.

[0039] As a preferred specific example under Embodiment 1 and Embodiment 2: such as Figure 2 , Figure 3 As shown, the compression actuator 12 includes an actuator section 121 that drives the compression component 16 to move and an installation section 122 connected to the actuator section 121. The drive component 11 and the clutch device 13 are arranged sequentially along the axial direction of the installation section 122.

[0040] By configuring the compression actuator 12 into an execution section 121 and an installation section 122, the function of the compression actuator 12 is divided. The execution section 121 directly drives the compressor 16 to complete the compression action, ensuring the directness of power transmission. The installation section 122 carries the drive component 11 and the clutch device 13, making the power input and clutch control independent modules. At the same time, by arranging the drive component 11 and the clutch device 13 sequentially along the axial direction of the installation section 122, the radial dimension increase caused by radial stacking is avoided, making the structure of the clutch air compressor more compact and facilitating the installation of the clutch air compressor.

[0041] As a preferred embodiment of this application, such as Figure 1 , Figure 3 As shown, the drive member 11 is rotatably mounted on the compression actuation shaft 12. The clutch device 13 includes a housing 131 rotatably mounted on the compression actuation shaft 12. The housing 131 is movably mounted on the compression actuation shaft 12. The drive member 11 is connected to the housing 131 in a transmission connection. The housing 131 is also connected to the compression actuation shaft 12 in a transmission connection. The clutch air compressor also includes a pusher 3, which drives the housing 131 to move so that the housing 131 is connected to or disconnected from the drive member 11 in a transmission connection.

[0042] By setting the drive component 11 to rotate around the compression actuation shaft 12, in the disengaged state, the drive component 11 can rotate around the compression actuation shaft 12. The housing 131 of the clutch device 13 can both rotate around the compression actuation shaft 12 and be moved around the compression actuation shaft 12. The pusher 3 drives the housing 131 to move, realizing the connection or disconnection of the housing 131 from the drive component 11. When the housing 131 is connected to the drive component 11, the power of the drive component 11 can be efficiently transmitted to the compression actuation shaft 12 for compression work. When the housing 131 is disconnected from the drive component 11, the power can be quickly cut off, avoiding the continuous operation of the compression actuation shaft 12 and improving the energy consumption control capability of the clutch air compressor.

[0043] In embodiment three, the rotation configuration of the housing 131 can be any of the following embodiments: Example 3: As Figure 3As shown, the housing 131 has a mounting cavity 132. The driving member 11 is connected to the rotating member 7, which is rotatably mounted on the compression actuation shaft 12. The inner wall of the mounting cavity 132 is provided with a friction member 133, which is in contact with the rotating member 7. The driving member 11 drives the housing 131 to rotate. Further, the rotating member 7 includes a mating member 71 that cooperates with the friction member 133. The rotating member 7 has multiple toothed grooves (not shown in the figure) spaced apart circumferentially. Multiple mating members 71 are sequentially spaced apart in the toothed grooves along the axial direction of the rotating member 7. Multiple friction members 133 are provided in the mounting cavity 132. The friction members 133 are disposed between two adjacent mating members 71. The friction members 133 abut against the mating members 71. The driving member 11 drives the housing 131 to rotate. When the housing 131 moves, the friction members 133 separate from the mating members 71, and the housing 131 stops rotating.

[0044] By providing a friction element 133 on the inner wall of the mounting cavity 132 of the housing 131, the rotating element 7 connected to the drive element 11 can be engaged or disengaged from the friction element 133 through the axial movement of the housing 131. When the rotating element 7 is engaged with the friction element 133, the power of the drive element 11 can be efficiently transmitted to the housing 131 through friction transmission, thereby driving the compression actuator 12 to move. The friction engagement method can reduce the impact of rigid connection and make the power transmission smoother.

[0045] Example 4: This example 4 is not illustrated. The difference from example 3 is that the driving component includes a driving part and a mating part connected to the driving part and extending toward the clutch device. The mating part is used to mate with the friction component.

[0046] As a preferred specific example 2 in embodiment 3, such as Figure 3 As shown, the clutch air compressor also includes a fixing member 4 fixedly connected to the compression actuator shaft 12. The fixing member 4 is disposed in the mounting cavity 132 and has multiple guide grooves (not shown in the figure). The multiple guide grooves are arranged sequentially at intervals along the circumference of the fixing member 4. The inner wall of the mounting cavity 132 has guide protrusions 134 that cooperate with the guide grooves. It will be clear to those skilled in the art that a clearance space can also be provided on the side of the guide protrusion 134 away from the fixing member 4. When the housing 131 moves, the fixing member 4 enters the clearance space, and the housing 131 is disengaged from the fixing member 4.

[0047] By setting a fixing member 4, the fixing member 4 cooperates with the guide protrusion 134 on the inner wall of the mounting cavity 132 of the housing 131 through the guide groove. When the guide protrusion 134 of the housing 131 moves along the guide groove, it can ensure that the fixing member 4 rotates synchronously with the housing 131, thereby improving the stability of power transmission.

[0048] As a preferred example 1 under specific example 2, such as Figure 3As shown, an elastic reset member 5 is provided between the fixing member 4 and the housing 131, and the elastic reset member 5 can drive the housing 131 to reset. Preferably, the elastic reset member 5 is a disc-type reset member, which includes a limiting section (not shown in the figure) that abuts against the fixing member 4 and a supporting section (not shown in the figure) that abuts against the housing 131. It will be clear to those skilled in the art that multiple elastic reset members 5 can be provided, and the multiple elastic reset members 5 are distributed sequentially at intervals along the circumference of the fixing member 4.

[0049] By incorporating the elastic reset component 5, the elastic reset component 5 can automatically reset the housing 131 using its own elastic potential energy after the driving component 11 stops driving. This allows the friction component 133 to engage with the rotating component 7, enabling the driving component 11 to rotate the housing 131. The reset action can be completed without additional power input, simplifying the control process and improving the equipment's response speed to changes in operating conditions. Simultaneously, the continuous preload of the elastic reset component 5 reduces the axial movement of the housing 131 during transmission, resulting in a tighter fit between the guide protrusion 134 and the guide groove, enhancing the continuity of power transmission.

[0050] Those skilled in the art will understand that when the elastic reset member 5 is provided, the pusher 3 can only move the housing 131 toward the drive member 11 to disengage the housing 131 from the drive member 11. The elastic reset member 5 can then reset the housing 131 to reconnect it with the drive member 11. Alternatively, the pusher 3 can move the housing 131 toward the drive member 11 to disengage it from the drive member 11. The pusher 3 can also move the housing 131 away from the drive member 11 to reconnect it with the drive member 11. The elastic reset member 5 serves as a buffer.

[0051] In Example 1, the elastic reset element 5 can be configured in any of the following ways: Example 1: Figure 3 As shown, the housing 131 is connected to the movable member 6 via the elastic reset member 5. The movable member 6 has a movable hole (not shown in the figure), and the fixing member 4 has a protrusion 41 extending toward the side opposite to the driving member 11. One of the movable hole and the protrusion 41 has a movable protrusion (not shown in the figure), and the other has a movable groove (not shown in the figure). The pushing member 3 is used to drive the movable member 6 to move. It will be clear to those skilled in the art that the movable member 6 can also be moved to compress the actuating shaft 12.

[0052] By setting the pusher 3 to drive the moving part 6, the moving protrusion can slide smoothly along the moving groove, driving the housing 131 to move synchronously, making the clutch switching process smoother. By setting the moving part 6, the moving part 6 provides a stable abutment part for the pusher 3, so that the driving force of the pusher 3 can be directly and concentrated on the moving part 6, improving driving efficiency. By setting the housing 131 to connect the moving part 6 through the elastic reset part 5, when the moving part 6 moves, the power is gradually transmitted to the housing 131 through the elastic reset part 5, realizing the smooth transmission of driving force and improving the stability of the movement of the housing 131.

[0053] Furthermore, such as Figure 2 , Figure 3 As shown, the pushing member 3 includes a telescopic member 31 that drives the moving member 6 to move, and an air supply assembly (not shown in the figure) for driving the telescopic member 31 to extend and retract. The air compression unit 1 includes a main body 14 and a receiving cavity 15 disposed in the main body 14, and the air supply assembly is disposed on the inner wall of the receiving cavity 15. Preferably, the air supply assembly includes an airbag (not shown in the figure), which is annularly disposed on the inner wall of the receiving cavity 15. The pushing member 3 also includes a controller connected to the main body 14.

[0054] By placing the air supply components on the inner wall of the receiving cavity 15, the internal space of the receiving cavity 15 is fully utilized, eliminating the need for additional installation space and making the overall structure of the clutch air compressor more compact.

[0055] Example 2: This example 2 is not shown in the figure. The housing 131 is connected to the joint. The joint is movably disposed on the compression actuation shaft 12. The joint is provided with a positioning hole. One of the positioning hole and the compression actuation shaft 12 is provided with a protrusion, and the other is provided with a guide groove. The pusher 3 is used to drive the joint to move.
