Description

Technical Field

[0001] The utility model relates to the field of clutches, and particularly relates to a structure of a clutch driven plate assembly. Background Art

[0002] A clutch is installed between the driving shaft and the driven shaft, inside the flywheel housing located between the engine and the gearbox, and is used to separate or engage the rotational motion of the two shafts. The output shaft of the clutch is the input shaft of the gearbox. During the driving process of an automobile, the driver can press or release the clutch pedal as needed to temporarily separate and gradually engage the engine and the gearbox, so as to cut off or transmit the power input from the engine to the transmission. A clutch is a commonly used component in mechanical transmission and can separate or engage the transmission system at any time. It has functions such as starting, stopping, reversing, and speed changing in the transmission system, and can also provide overload protection for the machine. The basic requirements for it are: smooth engagement, quick and complete separation, convenient adjustment and repair, small external dimensions, small mass, good wear resistance, sufficient heat dissipation capacity, convenient and labor-saving operation. Commonly used clutches are divided into two categories: jaw clutches and friction clutches.

[0003] A friction plate is installed on the driven plate of the clutch to contact the flywheel and transmit the power of the engine to the transmission. However, currently, the friction plate is not easy to disassemble from the driven plate, resulting in higher difficulty in replacing and repairing the friction plate, higher work burden on the staff, low efficiency, and poor self-protection effect of the current friction plate, making the friction plate prone to damage and having a lower service life, resulting in a higher replacement frequency of the friction plate;

[0004] In view of this technical problem, the present application proposes a structure of a clutch driven plate assembly. Content of the Utility Model

[0009] The friction plate transmits the power of the engine. One side of the friction plate is fixedly connected with an installation ring. The installation ring and the fixed ring are connected by a buckle assembly for installing the friction plate on the driven disc body. One side of the friction plate is provided with a buffer assembly for absorbing the vibration and impact of the friction plate.

[0013] Further, the buffer assembly includes a back plate fixedly connected to one side of the friction plate. A friction material layer is fixedly connected to one side of the back plate. A cavity is provided between the back plate and the friction material layer.

[0014] Further, a plurality of second springs are arranged inside the cavity. One end of the second spring is connected to one side of the back plate, and the other end of the second spring is connected to one side of the friction material layer.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Refer to Figures 1 - 3 , an embodiment provided by the present utility model: A clutch driven disc assembly structure includes:

[0030] A driven disc body 1 installed on the clutch, a fixing ring 6 is fixedly connected inside the driven disc body 1, square grooves 13 are opened on both the left and right sides of the fixing ring 6, an annular groove 14 is opened on the inner wall of the fixing ring 6, slots are opened on both the upper and lower sides of the annular groove 14, a friction plate 2 for transmitting the power of the engine, one side of the friction plate 2 is fixedly connected with an installation ring 5, and the installation ring 5 and the fixing ring 6 are connected to each other. Refer to Figures 4 - 6, grooves are provided on both the upper and lower sides of the mounting ring 5. A telescopic rod 8 is fixedly connected inside the groove. One end of the telescopic rod 8 is fixedly connected with a plug rod 10. The end of the plug rod 10 is inserted into the slot. A first spring 9 is sleeved on the outer wall of the telescopic rod 8. One end of the first spring 9 is connected to one side of the groove, and the other end of the first spring 9 is connected to one end of the plug rod 10. A metal plate 11 is fixedly connected to the outer wall of the plug rod 10. One end of the metal plate 11 is fixedly connected with a pull ring 12. The metal plate 11 is slidably connected in the groove;

[0031] Specifically, install the driven disk body 1 onto the clutch. Through the friction plate 2 in contact with the flywheel, the power of the engine is transmitted to the transmission. When it is necessary to replace the friction plate 2, only need to pull the pull ring 12 to make the metal plate 11 drive the plug rod 10 to move towards the annular groove 14, so that the plug rod 10 disengages from the slot and reaches the annular groove 14. Then rotate the mounting ring 5 to make the plug rod 10 rotate to the square groove 13, and the mounting ring 5 can be detached from the fixed ring 6. In this way, the friction plate 2 can be detached from the driven disk body 1, which improves the disassembly efficiency of the friction plate 2, reduces the difficulty of replacing or repairing the friction plate 2, reduces the workload of the staff and improves the work efficiency.

[0032] Refer to Figure 1 , Figure 2 and Figure 7 , one side of the friction plate 2 is fixedly connected with a back plate 4. One side of the back plate 4 is fixedly connected with a friction material layer 3. A cavity is provided between the back plate 4 and the friction material layer 3. A plurality of second springs 15 are arranged inside the cavity. One end of the second spring 15 is connected to one side of the back plate 4, and the other end of the second spring 15 is connected to one side of the friction material layer 3. A plurality of heat dissipation holes 7 are provided inside the friction plate 2;

[0033] Specifically, the plurality of heat dissipation holes 7 on the friction plate 2 are used to help dissipate heat and reduce the influence of high temperature on the performance of the friction plate 2. When the friction plate 2 is subjected to vibration or impact, the plurality of second springs 15 are used to absorb and mitigate the vibration and impact of the friction plate 2, reduce wear and noise, so as to improve the service life of the friction plate 2 through the mutual cooperation with the heat dissipation holes 7, reduce the number of times of replacing and repairing the friction plate 2, and save resources to a certain extent.

[0034] Working principle: Install the driven disk body 1 onto the clutch, make contact with the flywheel through the friction plate 2, and transmit the power of the engine to the transmission. When it is necessary to replace the friction plate 2, only need to pull the pull ring 12 to make the metal plate 11 drive the plug rod 10 to move towards the annular groove 14, so that the plug rod 10 disengages from the slot and reaches the annular groove 14. Then rotate the mounting ring 5 to make the plug rod 10 rotate to the square groove 13, and the mounting ring 5 can be disassembled from the fixed ring 6. In this way, the friction plate 2 can be disassembled from the driven disk body 1, and then the friction plate 2 can be replaced or repaired. The multiple heat dissipation holes 7 on the friction plate 2 are used to help dissipate heat and reduce the influence of high temperature on the performance of the friction plate 2. When the friction plate 2 is subjected to vibration or impact, the multiple second springs 15 are used to absorb and mitigate the vibration and impact of the friction plate 2, reduce wear and noise, and thus improve the service life of the friction plate 2 through the mutual cooperation with the heat dissipation holes 7.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
