Description

A power shift oil groove wet clutch friction plate mechanism Technical Field

[0001] This invention relates to the field of wet clutch friction plate technology, and in particular to a power shift oil groove wet clutch friction plate mechanism. Background Technology

[0002] Wet brake pads are a type of friction material used in wet brake systems. They typically consist of a friction material and a metal support, used to generate friction within the brake, thereby slowing or stopping the movement of mechanical equipment. Wet brake pads are usually made of wear-resistant friction materials and can operate in wet or lubricated environments. They are commonly used in equipment such as industrial machinery, vehicles, and motorcycles to provide reliable braking performance.

[0003] Chinese patent publication number "CN219888554U" discloses a novel wet clutch friction plate mechanism with an oil groove. The mechanism includes a clutch friction plate body, comprising an annular core plate, a first friction strip, a second friction strip, a third friction strip, and a fourth friction strip. The annular core plate has uniformly distributed splines on its inner circle. The paper base within the product is individually distributed, and the oil groove depth is equal to the paper base thickness. The paper base is designed with a general shape of evenly interspersed equilateral and inverted triangular circles. This design replaces the conventional radial oil groove with an oblique straight-through groove, increasing the contact area with the friction plate and thus better dissipating heat from the friction plate surface. This friction plate helps reduce the shear resistance of the lubricating oil between the friction materials while also improving the heat dissipation of the friction plate.

[0004] To reduce power loss during clutch disengagement, the aforementioned friction elements require a reduction in drag torque between the friction plates and steel plates. However, to improve both fuel efficiency and power performance for enhanced shift response, the following tendencies exist: the gap between the friction plates and steel plates is smaller than before; the drag torque generated by the intermediate oil film during idling is greater; and the heat dissipation performance of the friction plates is not high and needs improvement. Furthermore, the existing friction elements employ a one-piece design, often requiring replacement of the entire friction element when friction wear occurs. However, during wear, some parts of the friction element may be excessively worn while others remain usable, making replacement wasteful of resources. Additionally, the overall structure is inconvenient for manufacturing. Therefore, the current friction elements have high overall operating costs and require improvement. Summary of the Invention

The semi-ring base is configured in four groups. The two ends of the assembly block are slidably connected to the inner sides of the locking groove and receiving groove between two groups of semi-ring bases, respectively. A square groove is provided on the inner side of both the semi-ring base and the inner side of the assembly block. The limiting plate is slidably connected to the inner side of the square groove.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] Firstly, in this invention, the first oblique straight groove, the second oblique straight groove, the third oblique straight groove, the fourth oblique straight groove and the first straight groove can increase the contact area with the friction plate, extend the residence time of the lubricating oil, and better remove the heat from the surface of the friction plate, thereby improving the heat dissipation of the friction plate.

[0019] Secondly, in this invention, the first, second, third, and fourth oblique grooves, the first triangular groove, the second triangular groove, and the annular groove, which are distributed at intervals, can reduce the shear resistance of the lubricating oil between the annular friction plates, thus making it easier to reduce the drag torque.

[0020] Thirdly, in this invention, by setting up an assembly group, the friction pad can be used during operation by inserting the assembly block into the slot and receiving groove between two sets of semi-ring bases. Then, the limiting plate is inserted into the square groove, and the fixing bolt is threaded through the mating hole and connected to the inside of the mounting hole. At this time, the limiting plate can help fix the assembly block to the inside of the receiving groove and slot. By fixing the mounting block, the four sets of semi-ring bases can be connected. When disassembly is required, the limiting plate can be quickly removed by inserting a screwdriver through the slot and into the hexagonal button slot, and then the fixing bolt can be turned to quickly disassemble the four sets of semi-ring bases. The detachable assembly design allows the friction pad to be quickly disassembled and assembled, and the worn parts can be flexibly replaced, reducing the wear of the friction pad and also reducing the cost of use.

[0021] Fourthly, in this invention, the friction component on the assembly assembly allows the friction pad to be installed by inserting a limiting block through the slot into the limiting grooves on the front and back of the assembly block. When the bolt is turned to install the limiting plate, the limiting plate abuts against the assembly block as it moves downward. Due to the limitation of the slot, the limiting block cannot move. At this time, the limiting block slides against the top of the limiting groove. Both the limiting block and the limiting groove are L-shaped, and they engage with each other. Thus, the friction component can be quickly installed while assembling the four semi-ring bases. When the friction component needs to be disassembled, a screwdriver is inserted into the hexagonal knob slot, and the fixing bolt is turned to rotate it outward. At this time, the limiting plate is removed, and the assembly block is pulled out and moved outward. The limiting groove and the limiting block then engage and separate, allowing the friction component to be separated. This makes the friction pad easy to quickly disassemble and assemble, and facilitates flexible disassembly, maintenance, and use. Attached Figure Description

[0033] The annular assembly core plate 1 is composed of four assembly groups 101. Each of the four assembly groups 101 is provided with an assembly block 102 and a limiting plate 103.

An annular plate 109 is fixedly installed on the inner side of the inner support arc plate 108. Splines 20 are evenly arranged on the inner side of the annular plate 109.

[0034] A first oblique straight groove 15 is formed between the first friction strip 2 and the fourth friction strip 5; a second oblique straight groove 16 is formed between the second friction strip 3 and the third friction strip 4; a third oblique straight groove 17 is formed between the third friction strip 4 and the sixth friction strip 7; a fourth oblique straight groove 18 is formed between the fourth friction strip 5 and the fifth friction strip 6; and a first straight groove 19 is formed between the first friction strip 2, the second friction strip 3, and the fifth friction strip 6 and the sixth friction strip 7, which are adjacent in the counterclockwise direction.

[0035] Please refer to Figures 1-7. The first oblique straight through groove 15, the second oblique straight through groove 16, the third oblique straight through groove 17, the fourth oblique straight through groove 18 and the first straight through groove 19 can increase the contact area with the friction plate, extend the residence time of the lubricating oil, and better remove the heat from the surface of the friction plate, thereby improving the heat dissipation of the friction plate.

[0036] Please refer to Figures 1-7. Splines 20 are provided at equal intervals on the inner circle of the annular plate 109; the annular assembly core plate 1 can be easily installed through the splines 20.

[0037] Please refer to Figures 1-7. The annular assembled core plate 1 has a first surface and a second surface opposite to the first surface. The first friction strip 2, the second friction strip 3, the third friction strip 4, the fourth friction strip 5, the fifth friction strip 6 and the sixth friction strip 7 are spaced apart and uniformly fixed on the first surface and the second surface of the annular assembled core plate 1 along the radial direction, which can improve the wear resistance and stability of the annular assembled core plate 1.

[0038] Please refer to Figures 1-7. The dimensions of the first oblique groove 9, the second oblique groove 10, the third oblique groove 14, and the fourth oblique groove 13 range from 1 to 2.0 mm. The dimensions of the first oblique straight groove 15, the second oblique straight groove 16, the third oblique straight groove 17, the fourth oblique straight groove 18, and the first straight groove 19 range from 0.5 to 2.0 mm. By controlling the dimensions of the first oblique groove 9, the second oblique groove 10, the third oblique groove 14, and the fourth oblique groove 13, the shear resistance of the lubricating oil between the annular friction plates can be reduced. By controlling the dimensions of the first oblique straight groove 15, the second oblique straight groove 16, the third oblique straight groove 17, and the fourth oblique straight groove 18, the contact area with the friction plates can be increased to better remove heat from the surface of the friction plates.

[0039] Please refer to Figures 1-7. The inner included angle of the third friction strip 4 is A, and the angle A of the inner included angle of the third friction strip 4 is 20° to 60°. The inner included angle of the fourth friction strip 5 is B, and the angle B of the inner included angle of the fourth friction strip 5 is 40° to 80°. By controlling the angle range, it is easy to ensure the control of the residence time of the lubricating oil between the friction discs.

[0040] Please refer to Figures 1-7. The assembly 101 includes a semi-ring base 1011. One end of the inner side of the semi-ring base 1011 has a receiving groove 1012, and the other end has a locking groove 1013. Four sets of semi-ring bases 1011 are configured. The two ends of the assembly block 102 are slidably connected to the inner sides of the locking groove 1013 and the receiving groove 1012 between two sets of semi-ring bases 1011, respectively. Square grooves 1014 are provided on the inner sides of both the semi-ring bases 1011 and the assembly block 102. A limiting plate 103 is slidably connected... The mounting holes 104 are respectively opened on the inner side of the square groove 1014 of the semi-ring base 1011 and the square groove 1014 of the assembly block 102. Friction components 1015 are provided on both sides of the semi-ring base 1011. By setting the semi-ring base 1011 to cooperate with the assembly block 102, the mounting block can be slid into the slot 1013 and the receiving slot 1012 during use. Then, the limiting plate 103 is installed by fixing bolt 106, which can assist in the installation and connection of the semi-ring base 1011 and facilitate the combination and installation of this friction plate.

[0041] Please refer to Figures 1-7. The friction assembly 1015 includes a side arc groove 10151, a limiting groove 10152, a hollow groove 10153, and a mounting arc plate 10154. The side arc groove 10151 is formed on both sides of the semi-annular base 1011. The hollow groove 10153 is formed on both sides of the front and back of the semi-annular base 1011. The limiting groove 10152 is formed at the four corners of the front and back of the assembly block 102. Limiting blocks 10 are fixedly installed on both ends of the inner side of the mounting arc plate 10154. 155, the limiting block 10155 is inserted into the inner side of the limiting groove 10152 through the hollow groove 10153. The first friction strip 2, the second friction strip 3, the third friction strip 4, the fourth friction strip 5, the fifth friction strip 6, and the sixth friction strip 7 are all disposed on the outer side of the mounting arc plate 10154. The first friction strip 2, the second friction strip 3, the third friction strip 4, the fourth friction strip 5, the fifth friction strip 6, and the sixth friction strip 7 are all composed of friction bodies. By setting the friction assembly 1015, the friction plate... During use, the mounting arc plate 10154 can be attached to both sides of the semi-circular base. At this time, the limiting block 10155 is inserted into the inner side of the limiting groove 10152. After the assembly block 102 is assembled, it moves downwards, causing the slot 1013 and the limiting block 10155 to engage, thus quickly connecting the mounting arc plate 10154. When wear becomes severe, the assembly block 102 can be disassembled and pulled upwards, allowing the mounting arc plate 10154 to be tilted laterally. The friction pad can be easily pulled out for disassembly, allowing it to be synchronously snapped onto the mounting arc plate 10154 after the bottle is filled during use. This facilitates flexible disassembly, assembly, and maintenance of the friction pad. The inner side of the mounting arc plate 10154 is provided with anti-slip protrusions at equal intervals, and the inner side of the side arc groove 10151 is provided with anti-slip grooves at equal intervals. The anti-slip protrusions are inserted into the inner side of the anti-slip grooves, which can improve the friction between the inner sides of the semi-arc base and the mounting arc plate 10154 after they are assembled together, thereby improving the overall stability of the friction pad installation.

[0042] Please refer to Figures 1-7. The cross-sectional shape of the limiting block 10155 and the limiting groove 10152 is set to L-shape, the cross-sectional shape of the assembly block 102 is set to I-shape, the cross-sectional shape of the receiving groove 1012 and the card slot 1013 is also set to convex shape, the bottom view shape of the limiting plate 103 is rectangular, and the two ends of the annular plate 109 are provided with slots 1010. By setting the receiving groove 1012, the card slot 1013 and the assembly block 102 to be convex, the stability of the interlocking installation can be improved, and the slots 1010 can help reserve space for disassembly and assembly, making it convenient for disassembly and assembly.

[0043] Please refer to Figures 1-7. The composite friction body 22 includes a tungsten carbide base layer 221, which is disposed on the outer side of the composite friction body 22. A silicon carbide base layer 222 is fixedly connected to the inner side of the tungsten carbide base layer 221, and a titanium carbide base layer 223 is fixedly connected to the inner side of the silicon carbide base layer 222. The silicon carbide base layer 222 is a friction body made of silicon carbide material, which has high hardness, wear resistance and high temperature resistance, and can be used in high-speed friction and wear environments. The tungsten carbide base layer 221 is a friction body made of tungsten carbide material, which has extremely high hardness and wear resistance, and can be used as a friction material under high speed, high load and high temperature. The titanium carbide base layer 223 is a friction body made of titanium carbide material, which has good wear resistance and corrosion resistance. It can be seen that the use of the composite friction body 22 makes the device as a whole have strong friction resistance, which can improve its friction life and effect.

[0044] The working principle of this invention is as follows: The friction plate is assembled by inserting the assembly block 102 into the slot 1013 and receiving groove 1012 between two sets of semi-ring bases 1011. Then, the limiting plate 103 is inserted into the square groove 1014. The fixing bolt 106 is threaded through the mating hole 105 and connected to the inside of the mounting hole 104. The limiting plate 103 then helps to fix the assembly block 102 to the inside of the receiving groove 1012 and slot 1013. By fixing the mounting block, four sets of semi-ring bases 1011 can be connected. When disassembly is required, a screwdriver can be inserted through the slot 1010 into the hexagonal knob slot 107 to twist the fixing bolt 106 and quickly remove the limiting plate 103. The four semi-ring bases 1011 can be quickly disassembled, and the detachable assembly design allows for rapid disassembly and assembly of the friction pad, enabling flexible replacement of worn parts, reducing friction pad wear, and lowering operating costs. Through the friction component 1015 on the assembly 101, during use and installation, the limiting block 10155 can be inserted through the slot 10153 into the limiting grooves 10152 on the front and back of the assembly block 102. When the bolt is turned to install the limiting plate 103, the limiting plate 103 abuts against the assembly block 102, causing it to move downwards. Due to the limiting of the slot 10153, the limiting block 10155 cannot move, and at this time, the limiting block 10155 is in the limiting groove 10152. The inner side of 152 slides against the top. Both the limiting block 10155 and the limiting groove 10152 are L-shaped. At this time, the limiting block 10155 and the limiting groove 10152 engage with each other, allowing for quick installation of the friction assembly 1015 while assembling the four semi-ring bases 1011 of the assembly 101. When the friction assembly 1015 needs to be disassembled, a screwdriver is inserted into the inner side of the hexagonal knob slot 107, and the fixing bolt 106 is turned to rotate it outwards. At this time, the limiting plate 103 is removed, and the assembly block 102 is pulled outwards. The limiting groove 10152 and the limiting block 10155 then engage and separate, allowing the friction assembly 1015 to be separated. This facilitates quick disassembly and assembly of the friction plate as a whole. The friction plate is designed for easy and flexible disassembly and maintenance. The spaced-out first oblique groove 9, second oblique groove 10, third oblique groove 14, fourth oblique groove 13, first triangular groove 11, and second triangular groove 12, in conjunction with the annular groove 8, reduce the shear resistance of the lubricating oil between the annular friction plates, thus facilitating a reduction in drag torque. The first oblique straight groove 15, second oblique straight groove 16, third oblique straight groove 17, fourth oblique straight groove 18, and first straight groove 19 increase the contact area with the friction plate, extending the lubricating oil's residence time and better removing heat from the friction plate surface, thereby improving the friction plate's heat dissipation. The first straight groove 19 ensures that the flow of lubricating oil is not affected.
