Abstract
Description
Technical Field
[0001] This utility model relates to the field of clutch technology, specifically to a vibration reduction structure that doubles the transmitted torque. Background Technology
[0002] Clutch damping structures are key components in automotive transmission systems used to suppress torsional vibrations and buffer power shocks. They are mainly integrated into the clutch driven plate and reduce torque fluctuations between the engine and transmission through the synergistic effect of elastic buffering and damping energy dissipation, thereby protecting transmission components and improving ride smoothness.
[0003] Existing clutch damping structures are typically based on a composite mechanism of "elastic deformation + damping dissipation": the core components include damping springs, damping plates, driven disc bodies, and limiting mechanisms. When there are fluctuations in engine output torque (such as idling vibration or rapid acceleration impact), relative torsion occurs between the driven disc and the driving disc. The damping springs (usually helical springs distributed along the circumference) undergo compression or stretching deformation, converting the instantaneous impact into elastic potential energy, achieving flexible torque transmission, and avoiding damage to gears and other components from rigid impacts. At the same time, the damping plates (mostly friction plate groups) generate sliding friction during relative torsion, consuming vibration energy through frictional resistance and suppressing the continuous amplification of resonance phenomena. The limiting mechanism, by setting a maximum torsion angle, prevents excessive deformation and failure of the spring, ensuring structural stability.
[0004] Currently, clutch products are all driven plate assembly vibration damping system structures. Due to the limited space size of the clutch, the transmission of engine torque through the vibration damping structure can no longer exceed the upper limit. Now, for special engineering vehicles, it is necessary to design and develop a clutch vibration damping system that can transmit twice the engine torque. Utility Model Content
[0005] The technical problem to be solved by this utility model is that the existing vibration damping structure is limited by the size of the clutch space, and the transmission of engine torque by the vibration damping structure can no longer break through the upper limit. Now, for special engineering vehicles, it is necessary to design and develop a clutch vibration damping system that can transmit engine torque twice as much.
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a vibration damping structure that doubles the transmitted torque includes a long disc hub, a first vibration damping system provided at one end of the long disc hub, the first vibration damping system including a first vibration damping disc sleeved on the outer surface of the long disc hub, a second vibration damping disc sleeved on the outer surface of the long disc hub, and a first outer disc hub, the first outer disc hub being used to separate the first vibration damping disc and the second vibration damping disc, a limiting platform fixedly connected to one end of the long disc hub to support the first vibration damping disc, and a limiting platform provided at the other end of the long disc hub. The second vibration damping system includes a first damping disc sleeved on the outer surface of the long disc hub, a fourth damping disc sleeved on the outer surface of the long disc hub, and a second outer disc hub. The second outer disc hub is used to separate the third damping disc and the fourth damping disc. Several first limiting teeth are fixedly connected to the outer surface of the long disc hub. A pre-damping system is set in the middle of the long disc hub. The pre-damping system includes two limiting discs sleeved on the outer surface of the long disc hub. The surface of each limiting disc has a mounting groove, and a buffer spring is fixedly connected inside each mounting groove.
[0007] The beneficial effects of this utility model are: the long disc hub connects the first damping disc, the second damping disc, the third damping disc and the fourth damping disc to expand the contact surface for torque transmission; the buffer spring synchronously deforms to buffer and dampen vibration, improving the overall stability of the device; when the long disc hub rotates, it can drive the first damping disc, the second damping disc, the third damping disc and the fourth damping disc and the limiting disc to rotate simultaneously to transmit torque; the torque is doubled because the damping system doubles.
[0008] Based on the above technical solution, the present invention can be further improved as follows.
[0009] Furthermore, the surfaces of the first damping disc and the second damping disc are each provided with a number of first insertion holes, and the surfaces of the first outer disc hub near the first insertion holes are each provided with second insertion holes. The first insertion holes and the second insertion holes are located in the same vertical direction, and the first insertion holes and the second insertion holes are distributed at intervals with the first limiting teeth.
[0010] Furthermore, the first damping disc, the second damping disc, the third damping disc, and the fourth damping disc are all symmetrically distributed. The third damping disc and the fourth damping disc have the same external structure as the first damping disc and the second damping disc. The third damping disc has a first slot in the middle, and the long disc hub and the first limiting tooth are respectively inserted into the middle of the first slot.
[0011] Furthermore, a second slot is provided in the middle of the second outer hub, and the long hub and the first limiting tooth are sequentially engaged with the outer surface on which the second slot is sleeved.
[0012] Furthermore, grooves are provided on the sidewalls of the first limiting teeth for engaging and limiting.
[0013] Furthermore, a third slot is provided in the middle of the limiting plate, and the long plate hub and the first limiting tooth are sequentially inserted into the middle of the third slot.
[0014] Furthermore, the surface of the limiting plate is provided with several third insertion holes, and a rivet is inserted into the middle of the third insertion hole, with the rivet passing through the first insertion hole and the second insertion hole.
[0015] Furthermore, a through groove is provided in the middle of the long disc hub, and several second limiting teeth are fixedly connected to the inner side wall of the through groove.
[0016] The beneficial effect of adopting the above-mentioned further solution is that by providing a groove, a third slot, and a third insertion hole, the internal dimensions of the third slot are adapted to the external dimensions of the long disc hub and the first limiting tooth, thereby improving the accuracy and stability of the installation and positioning of the limiting disc.

In the description of this application, "a plurality of" means two or more, unless otherwise precisely specified.
[0028] like Figure 1-7As shown, the vibration damping structure that doubles the transmitted torque includes a long disc hub 1. A through groove 8 is provided in the middle of the long disc hub 1 for equipment connection. Several second limiting teeth 9 are fixedly connected to the inner sidewall of the through groove 8. The second limiting teeth 9 are used for support and limiting, improving the accuracy and stability of the long disc hub 1's installation and positioning. A first vibration damping system 2 is provided at one end of the long disc hub 1. The first vibration damping system 2 includes a first damping disc 201 sleeved on the outer surface of the long disc hub 1, and also includes a damping plate 201 sleeved on the first damping disc 201. The outer surface of the long disc hub 1 has a second damping disc 202 and a first outer disc hub 203. The first outer disc hub 203 separates the first damping disc 201 and the second damping disc 202. One end of the long disc hub 1 is fixedly connected to a limiting platform 4 to support the first damping disc 201. The other end of the long disc hub 1 is provided with a second damping system 3. The second damping system 3 includes the first damping disc 201 sleeved on the outer surface of the long disc hub 1, and also includes a damping system sleeved on the outer surface of the long disc hub 1. The fourth damping disc 302 and the second outer disc hub 303 are used to separate the third damping disc 301 and the fourth damping disc 302. Several first limiting teeth 5 are fixedly connected to the outer surface of the long disc hub 1. A pre-damping system 6 is provided in the middle of the long disc hub 1. The pre-damping system 6 includes two limiting discs 601 sleeved on the outer surface of the long disc hub 1. Mounting grooves 603 are formed on the surface of each limiting disc 601, and buffer springs 602 are fixedly connected inside each mounting groove 603. The long hub 1 connects the first damping disc 201, the second damping disc 202, the third damping disc 301, and the fourth damping disc 302 to expand the contact surface for torque transmission. The buffer spring 602 synchronously deforms elastically to buffer and dampen vibration, improving the overall stability of the device. When the long hub 1 rotates, it can drive the first damping disc 201, the second damping disc 202, the third damping disc 301, the fourth damping disc 302, and the limiting disc 601 to rotate simultaneously to transmit torque. Because the damping system doubles the torque, it doubles the torque.
[0029] The surfaces of the first damping disc 201 and the second damping disc 202 are each provided with a plurality of first insertion holes 204. The surfaces of the first outer disc hub 203 near the first insertion holes 204 are each provided with second insertion holes 205. The first insertion holes 204 and the second insertion holes 205 are located in the same vertical direction. The interiors of the first insertion holes 204 and the second insertion holes 205 can be fixed by inserting rivets. The first insertion holes 204 and the second insertion holes 205 are respectively distributed at intervals with the first limiting teeth 5, thereby improving the performance.
[0030] The first damping disc 201, the second damping disc 202, the third damping disc 301, and the fourth damping disc 302 are all symmetrically distributed. The third damping disc 301 and the fourth damping disc 302 have the same external structure as the first damping disc 201 and the second damping disc 202. The third damping disc 301 has a first slot 304 in the middle, and the long disc hub 1 and the first limiting tooth 5 are respectively inserted into the middle of the first slot 304. The second outer disc hub 303 has a second slot 305 in the middle, and the long disc hub 1 and the first limiting tooth 5 are sequentially engaged with the outer surface on which the second slot 305 is fitted.
[0031] The limiting plate 601 has a third slot 604 in the middle. The long plate hub 1 and the first limiting tooth 5 are inserted into the middle of the third slot 604 in sequence. The surface of the limiting plate 601 has several third insertion holes 605. A rivet is inserted into the middle of the third insertion hole 605. The rivet passes through the first insertion hole 204 and the second insertion hole 205. The side wall of the first limiting tooth 5 has a groove 7 to engage the limiting block and thus limit the limiting plate 601. The internal dimensions of the third slot 604 are adapted to the external dimensions of the long plate hub 1 and the first limiting tooth 5, which improves the accuracy and stability of the installation and positioning of the limiting plate 601.
[0032] Working principle: When using this vibration damping structure to double the transmitted torque, the operator first places the long disc hub 1 onto the movable shaft inside the transmission. The long disc hub 1 is used to accommodate the first damping disc 201, the second damping disc 202, the third damping disc 301, and the fourth damping disc 302. The first damping disc 201 is limited by the limiting platform 4, and the first limiting teeth 5 restrict the sliding displacement of the first damping disc 201, the second damping disc 202, the third damping disc 301, and the fourth damping disc 302 on the outer surface of the long disc hub 1. The multiple long disc hubs 1 provide support and limit the movement, thereby... To prevent the long disc hub 1 from sliding and deviating, when the long disc hub 1 rotates, it can drive the first damping disc 201, the second damping disc 202, the third damping disc 301, the fourth damping disc 302, and the limiting disc 601 to rotate simultaneously to transmit torque. The long disc hub 1 connects the first damping disc 201, the second damping disc 202, the third damping disc 301, and the fourth damping disc 302 to expand the contact surface for torque transmission. Because the damping system doubles the torque, the buffer spring 602 is installed in the middle of the two mounting slots 603 to improve the overall stability of the device by elastically deforming and buffering the vibration.
[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
