[0046] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0047] Embodiment 1

[0048] like Figure 1-Figure 3 As shown, a large torque angle clutch assembly specially used for a gas heavy truck comprises:

[0049] An output shaft 1 is provided on the inner ring surface and the internal gear 11 is meshed with the input shaft of the gearbox, a driven mechanism 2 is connected to the output shaft 1, a plurality of damping mechanisms 3 are arranged on the driven mechanism 2 at equal intervals along the circumference of the output shaft 1, and a damping plate 4 is connected to the driven mechanism 2 and used for limiting the output shaft 1 and the damping mechanism 3 from being separated from the driven mechanism 2;

[0050] The vibration reduction mechanism 3 includes a first spring 31 with an arc-shaped axis arranged in the mounting hole 211 of the driven mechanism 2, a second spring 32 coaxially arranged inside the first spring 31, and two connecting components 33 with one side respectively positioned and inserted into the inner rings at both ends of the first spring 31 and the second spring 32 and the other side positioned and connected to the connecting groove 212 in the mounting hole 211.

[0051] In this embodiment, the second spring 32 is positioned and connected inside the first spring 31 by setting a connecting component 33, and the space inside the first spring 31 is used to set the second spring 32, so that the space utilization rate is good, the torsion angle and torque of the single vibration reduction mechanism 3 are improved, and the vibration reduction effect is good. The first spring 31 and the second spring 32 are bent and connected in the mounting hole 211 through the connecting component 33, and then adapted to the rotation direction of the driven mechanism 2, and are easy to deform with the rotation of the driven mechanism 2, so that the structure is more reasonable, and the vibration reduction effect is further improved.

[0052] It should be noted that, since the available space on the driven mechanism 2 is limited, the present application preferably has five damping mechanisms 3 to ensure the rational use of the space on the driven mechanism 2 and to make the first spring 31 and the second spring 32 of appropriate size, thereby ensuring the requirements of large torsion angle and large torque while facilitating assembly during production.

[0053] Further, if Figure 3-Figure 5 As shown, the connecting assembly 33 includes a connecting seat 331, a first positioning block 332 arranged on one side of the connecting seat 331 and positioned and inserted in the inner ring of the first spring 31, a second positioning block 333 arranged on the first positioning block 332 and positioned and inserted in the inner ring of the second spring 32, and a connecting block 334 arranged on the other side of the connecting seat 331 and connected to the connecting groove 212.

[0054] In this embodiment, the first spring 31 and the second spring 32 are positioned and connected by setting a connecting seat 331 to cooperate with the first positioning block 332 and the second positioning block 333 on one side, and at the same time cooperate with the connecting block 334 on the other side to connect the connecting groove 212 to realize the connection and fixation between the first spring 31, the second spring 32 and the driven mechanism 2.

[0055] It should be noted that the connecting block 334 is a hemispherical structure, and the connecting block 334 can be easily slid into and connected to the connecting groove 212 under the elastic force of the first spring 31 and the second spring 32 .

[0058] Further, if Figure 2-Figure 5 As shown, the driven mechanism 2 includes a friction plate 21, a driven plate 22 connected to the friction plate 21 and combined with the friction plate 21 to form a mounting hole 211 and a connecting groove 212, a driven gear 23 formed on the inner annular surface of the friction plate 21 and meshing with the external gear 12 on the outer annular surface of the output shaft 1, and a plurality of side tooth grooves 24 formed on the driven plate 22 at equal intervals along the circumference of the output shaft 1 and used to connect to the four peripheral racks 41 on the damping plate 4.

[0059] In this embodiment, the friction plate 21 and the driven plate 22 are connected to form the mounting hole 211 and the connecting groove 212. Not only is the connecting groove 212 located on one side of the friction plate 21 and the driven plate 22, which is convenient for the forming process of the connecting groove 212, but the connecting groove 212 is also large enough to improve the stability of the connection. Moreover, the connected damping mechanism 3 is located between the friction plate 21 and the driven plate 22, and the damping effect in the forward and reverse directions is relatively balanced. In addition, a side tooth groove 24 is provided on the driven plate 22, and the connection and assembly of the damping plate 4 is achieved by connecting the side rack 41.

[0060] Embodiment 2

[0061] like Figure 1-Figure 2 as well as Figure 6-Figure 7 As shown, an automatic assembly system of a clutch assembly is used to assemble the above-mentioned large torque angle clutch assembly dedicated to a gas heavy truck, comprising:

[0062] A conveying mechanism 5 for positioning and conveying the clutch assembly, an assembling mechanism 6 and a welding mechanism 7 sequentially arranged along the conveying direction of the conveying mechanism 5, the assembling mechanism 6 being used to assemble a plurality of damping mechanisms 3 in the driven mechanism 2 on the conveying mechanism 5, and the welding mechanism 7 being used to weld and connect the driven mechanism 2 and the damping plate 4;

[0063] The conveying mechanism 5 includes a first conveying component 51, a support plate 52 rotatably disposed on the first conveying component 51 and used to support the driven mechanism 2, and a support gear 53 disposed on the support plate 52 and meshed with the internal gear 11, thereby limiting the displacement movement of the driven mechanism 2.

[0064] In this embodiment, by setting a first conveying assembly 51 to cooperate with the support plate 52 and the rotating support gear 53, the driven mechanism 2 is positioned and conveyed to the assembly mechanism 6 and the welding mechanism 7 to realize automatic assembly of the vibration damping mechanism 3 and automatic welding connection of the vibration damping plate 4. The degree of automation is high, manual intervention is avoided, and safety hazards during production are reduced.

[0065] In detail, when in use, first, the driven mechanism 2 is supported on the support plate 52, and then the internal gear 11 of the output shaft 1 is meshed with the support gear 53 and the external gear 12 is meshed with the driven gear 23 on the inner ring surface of the driven mechanism 2. Then the first conveying component 51 conveys the driven mechanism 2 to the assembly mechanism 6. After the assembly mechanism 6 assembles the first spring 31, the second spring 32 and the two connecting components 33 into the vibration reduction mechanism 3, the assembly mechanism 6 squeezes the vibration reduction mechanism 3 to shrink and bend it so that it can be installed in multiple installation holes 211 in the driven mechanism 2, and cooperates with the rotation of the support plate 52 to position and install multiple vibration reduction mechanisms 3. Finally, the welding mechanism 7 welds the vibration reduction plate 4 to the driven mechanism 2 to limit the output shaft 1 and the vibration reduction mechanism 3 from being separated from the driven mechanism 2, thereby completing the automated production.

[0066] It should be noted that the first conveying assembly 51 is a conveyor belt structure. When the support plate 52 is transmitted to the top of the first conveying assembly 51, the internal gear 11 can be meshed with the support gear 53 manually or by a robot to support the driven mechanism 2; when the support plate 52 is transmitted to the bottom of the first conveying assembly 51, the assembled clutch assembly can automatically disengage the support gear 53 to complete the unloading;

[0067] In addition, there are multiple supporting plates 52 and supporting gears 53 to facilitate production at different workstations at the same time, thereby achieving high production continuity and high production efficiency.

[0068] Further, if Figure 8 As shown, the assembly mechanism 6 includes a positioning component 61, an assembly component 62 and a second conveying component 63 arranged on the outside of the conveying mechanism 5, the positioning component 61 is used to position the second spring 32 in the first spring 31 and position the two to overlap axially, the assembly component 62 is used to assemble the connecting component 33, the first spring 31 and the second spring 32 into a clutch assembly and to assemble the clutch assembly on the driven mechanism 2, and the second conveying component 63 is used to position and convey the first spring 31, the second spring 32 and the connecting component 33.

[0069] In this embodiment, the second conveying assembly 63 is provided to cooperate with the positioning assembly 61 and the assembling assembly 62 to realize the automatic assembly of the vibration reduction assembly itself and the automatic assembly between the vibration reduction assembly and the driven mechanism 2 .

[0070] In detail, when in use, the second conveying component 63 conveys the first spring 31 and the second spring 32 to the positioning component 61 for positioning, and then the connecting component 33 conveyed by the second conveying component 63 is connected to the two ends of the first spring 31 and the second spring 32 through the assembling component 62 to assemble into the vibration damping mechanism 3, and finally the assembling component 62 is able to squeeze the vibration damping mechanism 3 to shrink and bend, and then the vibration damping component is bent and assembled on the driven mechanism 2.

[0071] It should be noted that the present application does not limit the specific structure of the second conveying assembly 63. The following only provides a structure for reference, for example:

[0072] It includes a spring feeder 631 arranged on the outside of the conveying mechanism 5 and used for positioning and conveying the first spring 31 and the second spring 32 to the positioning component 61, a conveyor belt 632 arranged on the outside of the conveying mechanism 5 and used for conveying the connecting component 33, and a guide plate 633 arranged on the conveyor belt 632 and used for guiding the positioning of the connecting component 33 and the assembly component 62; the positioning and conveying of the first spring 31, the second spring 32 and the connecting component 33 are realized.

[0073] Further, if Figure 9-10 As shown, the positioning assembly 61 includes a frame 611 arranged on the outside of the conveying mechanism 5, a support seat 612 arranged on the frame 611 and used to support the first spring 31 and the second spring 32, a plurality of first positioning rods 613 arranged on the support seat 612 at equal intervals along the circumference of the first spring 31 and movable in the radial direction and used to support and position the outer ring of the first spring 31, a plurality of second positioning rods 614 arranged on the support seat 612 at equal intervals along the circumference of the first spring 31 and movable in the radial direction and used to support and position the inner ring of the second spring 32, and a first driving member 615 arranged on the frame 611 and used to drive the first positioning rod 613 and the second positioning rod 614 to move radially inward or outward.

[0074] In this embodiment, the first positioning rod 613 and the second positioning rod 614 are provided to respectively position the outer ring of the first spring 31 and the inner ring of the second spring 32. The positioning structure is reasonable, which facilitates the support seat 612 to support the bottom of the first spring 31 and the second spring 32. The positioning effect is good, which facilitates the assembly of the subsequent connecting component 33.

[0075] In detail, when in use, multiple first positioning rods 613 move radially outward, and multiple second positioning rods 614 move radially inward. Then, the first spring 31 and the second spring 32 are conveyed to between the first positioning rod 613 and the second positioning rod 614 through the spring feeder 631, and the bottom of the first spring 31 and the second spring 32 are supported by the conveying support seat 612. Finally, multiple first positioning rods 613 move radially outward and inward to support and position the outer ring of the first spring 31, and multiple second positioning rods 614 move radially outward to support and position the inner ring of the second spring 32.

[0076] It should be noted that the present application does not limit the specific structure of the first driving member 615. The following only provides a structure for reference, for example:

[0078] The first driving member 615 includes a driving disk 6151 rotatably disposed on the support seat 612, a first driving groove 6152 disposed on the driving disk 6151 and slidably connected to the first positioning rod 613, and a second driving groove 6153 disposed on the driving disk 6151 and slidably connected to the second positioning rod 614. When the driving disk 6151 rotates, the first positioning rod 613 and the second positioning rod 614 slide in the first driving groove 6152 and the second driving groove 6153 respectively, thereby forcing the first positioning rod 613 and the second positioning rod 614 to move radially inward and outward respectively.

[0079] Further, if Figure 9-12 As shown, the assembly component 62 includes a first base 621 that is movable up and down and rotatably arranged on the frame 611, two clamping arms 622 that are opened and closed on the first base 621 and are used to clamp the outer ring of the first spring 31, a telescopic rod 623 that is movable in the direction of approaching or moving away from the conveying mechanism 5 and axially rotatably arranged on the frame 611, a second base 624 that is arranged at the lower end of the telescopic rod 623, and two first clamping rods 625 and second clamping rods 626 that are opened and closed on the second base 624. When the two first clamping rods 625 and the second clamping rods 626 are closed, not only the outer ring surface of the connecting component 33 and the two ends of the clutch assembly can be clamped, but also the clutch assembly can be squeezed to bend by adjusting the different closing degrees of the first clamping rod 625 and the second clamping rod 626.

[0080] In this embodiment, the direction of the vibration reduction mechanism 3 is adjusted by setting a rotating first base 621 in cooperation with the clamping arm 622, and the first clamping rod 625 and the second clamping rod 626 are coordinated with the extension and retraction of the telescopic rod 623 to clamp the connecting component 33 for assembly and clamp and squeeze the vibration reduction mechanism 3 to bend for assembly, thereby realizing the bending assembly of the vibration reduction mechanism 3.

[0081] In detail, when in use, first, the telescopic rod 623 is telescoped to cooperate with the first clamping rod 625 and the second clamping rod 626 to close and clamp the connecting component 33, and then the telescopic rod 623 is extended to insert the connecting component 33 into the first spring 31 and the second spring 32, and the second machine base 624 is rotated during the process, so that the connecting component 33 is screwed into one end of the first spring 31 and the second spring 32, and the assembly is convenient, and then the first machine base 621 is rotated to cooperate with the clamping arm 622 to adjust the first spring 31 and the second spring 32 to reverse, and then the connecting component 33 can be connected to the other end of the first spring 31 and the second spring 32 to assemble into the vibration reduction mechanism 3, and finally the first machine base 621 is rotated to cooperate with the clamping arm 622 to adjust the vibration reduction mechanism 3 to a horizontal position, and the two first clamping rods 625 and the second clamping rod 626 are closed to clamp the two ends of the vibration reduction mechanism 3, and the different closing degrees of the first clamping rod 625 and the second clamping rod 626 are adjusted to squeeze the clutch assembly to bend, so that the vibration reduction mechanism 3 can be bent and assembled in the driven mechanism 2.

[0082] It should be noted that when the first clamping rod 625 and the second clamping rod 626 at both ends of the second base 624 clamp the two ends of the clutch assembly, the connecting block 334 is connected between the first clamping rod 625 and the second clamping rod 626. In the process of squeezing the clutch assembly to bend and deform, the two ends of the clutch assembly can be restricted to prevent it from falling off.

[0083] Further, if Fig.13 As shown, the fusion welding mechanism 7 includes a third conveying component 71, an assembling component 72 and a fusion welding component 73 arranged on the outside of the conveying mechanism 5, the third conveying component 71 is used to convey the vibration damping plate 4, the assembling component 72 is used to position and assemble the vibration damping plate 4 on the driven mechanism 2, and the fusion welding component 73 is used to fusion weld the driven mechanism 2 and / or the vibration damping plate 4 to achieve connection between the two.

[0084] In this embodiment, the vibration damping disc 4 transported by the transport assembly is assembled on the driven mechanism 2 by setting the assembly assembly component 72, and then the two are welded together by the welding component 73 to achieve the connection and assembly between the vibration damping disc 4 and the driven mechanism 2.

[0085] It should be noted that the present application does not limit the specific structure of the welding assembly. The following only provides one structure for reference, for example:

[0086] It includes a body 731 arranged on the outside of the conveying mechanism 5, a pressing plate 732 that is movable up and down and axially rotated on the body 731 and is used to press the vibration damping disk 4, a welding head 733 that is movable up and down on the body 731 and is used to weld the side rack 41 and / or the side tooth groove 24, and an abutment plate 734 that is movably arranged on the body 731 and is used to energize the driven mechanism 2, and the abutment plate 734 abuts against the outer wall of the driven mechanism 2 corresponding to the welding position of the welding head 733; after the pressing plate 732 presses the vibration damping disk 4 to position it, the ground plate abuts against the outer wall of the driven mechanism 2 to energize it, and then the welding head moves downward to contact the driven mechanism 2 and / or the vibration damping disk 4 for welding, and presses the welded materials to pile them into blocks to form a limiting connection. At this time, the ground plate abuts and supports the outer wall of the driven mechanism 2 corresponding to the welding position of the welding head 733 to avoid deformation of the driven mechanism 2 when the welding head is pressed.

[0087] Further, if Figure 14-15 As shown, the assembly component 72 includes a third machine base 721 that moves up and down and moves in a direction close to or away from the conveying mechanism 5 and is arranged on the third conveying component 71, a plurality of clamping plates 722 that are evenly spaced along the circumference of the vibration damping plate 4 and are opened and closed and are arranged on the third machine base 721 and are used to clamp a plurality of side racks 41 on the vibration damping plate 4, a second driving member 723 that is arranged on the third machine base 721 and is used to drive the plurality of clamping plates 722 to open and close, a baffle 724 that is arranged on the third conveying component 71 and abuts against two adjacent side racks 41 for limiting the movement and rotation of the vibration damping plate 4, and a push plate 725 that is movably arranged on the third conveying component 71 and is used to push the vibration damping plate 4 to slide on the baffle 724 to directly below the third machine base 721.

[0088] In this embodiment, the baffle 724 is provided to cooperate with the push plate 725 to facilitate the positioning of the vibration damping plate 4. The multiple clamping plates 722 can clamp the multiple side racks 41 on the vibration damping plate 4, and then cooperate with the movement of the third machine base 721 to position the vibration damping plate 4 and connect it to the driven mechanism 2.

[0089] In detail, when in use, the third conveying assembly 71 conveys the vibration damping disc 4 to abut against the conveying baffle 724, and the vibration damping disc 4 is able to rotate until the two adjacent side racks 41 on the vibration damping disc 4 abut against the baffle 724 to achieve positioning, and then the conveying push plate 725 pushes the vibration damping disc 4 to slide to the bottom of the third machine base 721, and the third machine base 721 moves and cooperates with the closing of the clamping plate 722 to clamp multiple side racks 41 to clamp the vibration damping disc 4, and finally, the third machine base 721 moves to press the vibration damping disc 4 into the driven mechanism 2, and then the clamping plate 722 opens to complete the positioning and assembly of the vibration damping disc 4.

[0090] It should be noted that the clamping plate 722 is a T-shaped structure. When clamping the side rack 41, the T-shaped structure abuts against the upper surface of the side rack 41, thereby pushing the side rack 41 to connect to the side tooth groove 24 of the driven mechanism 2;

[0091] In addition, the driving principle of the second driving member 723 may be the same as the driving principle of the first driving member 615 , and the third conveying assembly 71 is a conveyor belt structure, which will not be described in detail herein.

[0096] Next, the assembly mechanism 6 assembles the first spring 31 and the second spring 32 coaxially between the two connecting components 33, and uses the space inside the first spring 31 to set the second spring 32;

[0097] Then, the assembled multiple vibration damping mechanisms 3 are extruded and bent by the assembly mechanism 6 and then assembled into multiple mounting holes in the driven mechanism 2 in coordination with the rotation positioning of the support plate 52, so that the multiple bent vibration damping mechanisms 3 are adapted to the rotation direction of the driven mechanism 2;

[0098] Finally, the welding mechanism 7 welds the damping disc 4 to the driven mechanism 2 on the conveying mechanism 5, restricting the output shaft 1 and the damping mechanism 3 from being separated from the driven mechanism 2, thereby completing the automated production.
