Description

An isolation elastomer structure with energy-saving friction plate Technical Field

[0001] The present invention relates to the field of friction plates, and in particular to an isolation elastic body structure of a friction plate with energy-saving function. Background Art

[0002] Multi-disc friction plates are widely used in brakes and clutches of various engineering machinery, petroleum, coal mining, geological drilling, shipbuilding, marine engineering, and military equipment. The number of applications worldwide is calculated in the billions. The resulting material consumption and friction loss energy are quite enormous. How to separate the dynamic and external friction plates in the non-braking state, and then reduce the friction between the dynamic and external friction plates during relative rotation, thereby reducing wear, energy consumption and heat generation, is the key difficulty in the current technological development.

[0003] To solve the above problems, the applicant has carried out a lot of research and development work, and proposed a structure for reducing friction when the friction plate in the brake or clutch is disengaged, with application number 202020687140.1, and a brake with application number 202011466262.9.

[0004] The structure for reducing friction when the friction plates in a brake or clutch are disengaged and operating, with application number 202020687140.1, specifically discloses that N holes are provided near the outer ring on each outer friction plate connected to the housing, a positioning shaft a is provided in each hole, and N springs are provided between every two adjacent outer friction plates, the springs are sleeved on the positioning shaft a, and one end or both ends of the N positioning shafts a are fixed on a baffle fastened to the housing; M holes are provided near the outer circle of the spline gear on each inner friction plate connected to the spline gear, a positioning shaft b is provided in each hole, and M springs are provided between every two adjacent inner friction plates, the springs are sleeved on the positioning shaft b, and the two ends of the M positioning shafts b are respectively fixed on the baffle a and the baffle b; the left and right shaft stops on the spline gear are used to position the baffle a and the baffle b, respectively. The structural parts have many assembly steps, resulting in high production costs. In actual use, the positioning shafts a and b will bend and deform or even break due to the vibration of the corresponding outer friction plates and inner friction plates. At the same time, the positioning shafts also have surface coaxiality requirements during the production and processing process. The production process requirements are high, and there are cases of processing scrap and breakage during the processing, which further increases the production cost, as shown in Figure 1.

[0005] The brake application with application number 202011466262.9 employs a small, oil-resistant, NBR O-shaped spacer bonded to the right side of each inner friction plate, near the main shaft, and a large, oil-resistant NBR O-shaped spacer bonded to the right side of each outer friction plate, away from the main shaft. The O-ring acts as a spring, pushing the friction plates apart and maintaining a certain gap when the brake is engaged. When the brake is engaged, the corresponding friction plates are compressed, but the O-ring's compression and deformation do not affect the friction plate's compression. When the brake is disengaged, the elasticity of the O-ring maintains an equal spacing between the disengaged inner and outer friction plates. However, in actual use, the oil-resistant NBR O-rings are prone to adhesive failure due to frequent compression and reset, resulting in a short lifespan. This can lead to wear and displacement of the O-rings, which can cause brake or clutch failure, as shown in Figure 2.

[0006] In order to solve the above problems, the present invention proposes an isolation elastomer structure with a friction plate having an energy-saving function. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide an isolation elastomer structure of a friction plate with energy-saving function which has a simple structure, is easy to assemble, can reliably separate the inner friction plate and the outer friction plate, and has a long service life.

[0008] In order to solve the above technical problems, the present invention is solved through the following technical solutions: an isolation elastomer structure with energy-saving friction plates, including multiple inner friction plates and multiple outer friction plates arranged in a brake or clutch, and elastic isolation members are arranged between two adjacent inner friction plates and two adjacent outer friction plates. The number of elastic isolation members contained in each group of adjacent inner friction plates or adjacent outer friction plates is N, where N≥2. The elastic isolation members are used to separate two adjacent inner friction plates or two adjacent outer friction plates so that a gap is maintained between the adjacent inner friction plates and the outer friction plates. The elastic isolation members include an elastomer and a positioning portion. The elastomer is located between adjacent inner friction plates or adjacent outer friction plates. The inner friction plates and outer friction plates are both provided with positioning holes corresponding to the elastic isolation members, and the positioning portion of the elastic isolation member is embedded in the corresponding positioning hole.

[0009] Furthermore, positioning parts can be provided on both sides of the elastomer, and the positioning parts are embedded in adjacent inner friction plates or adjacent outer friction plates; the advantage is that providing positioning parts on both sides of the elastomer can further ensure the stability of the elastomer between the two adjacent inner friction plates or between the two adjacent outer friction plates, and prevent it from falling off.

[0010] Furthermore, the elastic isolation member is made of rubber or a composite material of rubber and plastic, which has elasticity. The advantage is that the elastic isolation member made of rubber or a composite material of rubber and plastic is low in cost and has high stability.

[0011] Furthermore, the elastic isolation member is a spring made of metal material with a positioning portion; the advantage is that the elastic isolation member made of metal material has high strength and is suitable for high-strength hydraulic brakes, and the restoring force after compression is more reliable.

[0012] Furthermore, the number of elastic isolators set between two adjacent inner friction plates is the same as the number of elastic isolators set between two adjacent outer friction plates; or the number of elastic isolators set between two adjacent inner friction plates is different from the number of elastic isolators set between two adjacent outer friction plates; the advantage is that when the number of elastic isolators set between two adjacent inner friction plates is the same as the number of elastic isolators set between two adjacent outer friction plates, it can ensure that the elastic isolators exert the same force on the inner friction plates and the outer friction plates, thereby ensuring the balance of the separation distance, thereby reducing the energy loss caused by the contact between the inner friction plates and the outer friction plates in the non-braking state; when the number of elastic isolators set between two adjacent inner friction plates is different from the number of elastic isolators set between two adjacent outer friction plates, it can reduce the manufacturing cost while ensuring the reliable separation between the inner friction plates and the outer friction plates.

[0013] Furthermore, the size of the elastomer is larger than the size of the positioning portion, and the thickness of the positioning portion is not greater than the thickness of the corresponding inner friction plate or outer friction plate; the advantage is that by setting a large-sized elastomer, the effective area between the elastomer and the corresponding inner friction plate and outer friction plate can be guaranteed, thereby ensuring that the elastomer can reliably drive the outer friction plate or inner friction plate to separate and ensure the gap.

[0014] Furthermore, the elastic isolators between adjacent inner friction plates do not interfere with the outer friction plates, and their positions can be set arbitrarily; the elastic isolators between adjacent outer friction plates do not interfere with the inner friction plates, and their positions can be set arbitrarily; the advantage is that by arranging the inner friction plates and the outer friction plates in a staggered manner, the assembly and use of the elastic isolators can be facilitated, avoiding interference between the elastic isolators and the corresponding inner friction plates and outer friction plates, which would reduce the service life of the elastic isolators.

[0015] Furthermore, the inner friction plates and the outer friction plates are arranged in sequence at intervals, and the elastic isolation members between multiple groups of adjacent inner friction plates are coaxially arranged, and the elastic isolation members between multiple groups of adjacent outer friction plates are coaxially arranged; or the elastic isolation members between multiple groups of adjacent inner friction plates are non-coaxially arranged, and the elastic isolation members between multiple groups of adjacent outer friction plates are non-coaxially arranged; the advantage is that the coaxial arrangement of the elastic isolation members can effectively improve production efficiency, and at the same time ensure that the force acting when the elastic isolation members push the adjacent inner friction plates or outer friction plates outward is on the same straight line, thereby improving the integrity.

[0016] Furthermore, the elastomer and the positioning portion are an interconnected whole, and the shapes of the elastomer and the positioning portion are arbitrary; the advantage is that the one-piece molded elastomer and the positioning portion can effectively improve the integrity and stability of the elastic isolation component, and ensure the reliability of the fit between the elastic isolation component and the corresponding inner friction plate and outer friction plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects: by providing elastic spacers between multiple adjacent inner friction plates, and between multiple adjacent outer friction plates, the separation distance between the inner friction plates and the outer friction plates can be effectively maintained, thereby effectively reducing the friction between the inner friction plates and the outer friction plates in the non-braking state, thereby reducing energy loss and friction noise caused by friction in the non-braking state. The elastic spacer of this design includes an elastomer and a positioning portion. The positioning portion can effectively assemble the elastic spacer on the corresponding inner friction plate or outer friction plate, so that the elastic spacer and the inner friction plate or outer friction plate form a whole, effectively improving stability, and thus avoiding the problems of slippage and failure of the bonded O-ring and deformation of the positioning shaft in the prior art.

The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

Therefore, the above terms should not be understood as limiting the present invention.

[0029] Embodiment 1: As shown in FIG4 , an isolation elastic body structure of a friction plate with an energy-saving function includes a plurality of inner friction plates 1 and a plurality of outer friction plates 2 disposed within a brake or clutch. The inner friction plates 1 and the outer friction plates 2 are annular with a hole in the middle. The inner friction plates 1 and the outer friction plates 2 are arranged in sequence. An elastic isolation member 3 is disposed between two adjacent inner friction plates 1 and two adjacent outer friction plates 2. Each group of adjacent inner friction plates or adjacent outer friction plates includes N elastic isolation members, where N ≥ 2. The elastic isolation member 3 is used to separate two adjacent inner friction plates 1 or two adjacent outer friction plates 2 so that a gap is maintained between the adjacent inner friction plates and the outer friction plates. The elastic isolation member 3 includes an elastic body 3.1 and a positioning portion 3.2. The elastic body 3.1 is located between two adjacent inner friction plates 1 or two adjacent outer friction plates 2. The inner friction plates 1 and the outer friction plates 2 are each provided with a positioning hole corresponding to the elastic isolation member 3. The positioning portion 3.2 of the elastic isolation member is embedded in the corresponding positioning hole.

[0030] When the inner friction plates 1, outer friction plates 2, and elastic spacers 3 are used in a brake, the inner and outer friction plates 1 and 2 are sequentially mounted on the brake piston. The ends of the brake piston are equipped with a stopper and a right seal to prevent the inner friction plates from slipping. When in the braking compression state, adjacent inner and outer friction plates 1 and 2 compress the elastic spacers 3, causing them to contact each other and achieve friction braking. When in the non-braking state, the elastic spacers 3 exert a force on the adjacent inner and outer friction plates 1 and 2, forcing them apart. Thus, by providing the elastic spacers 3 between adjacent inner friction plates 1 and between adjacent outer friction plates 2, the separation distance between the inner and outer friction plates 1 and 2 is maintained, effectively reducing friction between the inner and outer friction plates 1 and 2 in the non-braking state, thereby reducing energy loss and friction noise caused by friction in the non-braking state. At the same time, the elastic isolation member 3 of the present design includes an elastic body 3.1 and a positioning portion 3.2. The elastic isolation member 3 can be effectively assembled on the corresponding inner friction plate 1 or outer friction plate 2 through the positioning portion 3.2, so that the elastic isolation member 3 and the inner friction plate 1 or outer friction plate 2 form a whole, effectively improving the stability, thereby avoiding the problem of slippage failure of the adhesive O-ring in the existing design and the deformation of the positioning shaft.

[0031] On the basis of the above, in order to further improve the stability of the elastic isolation member 3, positioning parts 3.2 can be set on both sides of the elastic body 3.1, and the positioning parts 3.2 are embedded in the two adjacent inner friction plates 1 or the two adjacent outer friction plates 2, so as to avoid the elastic isolation member 3 from falling off.

[0032] On the basis of Example 1, the elastic isolation member 3 is composed of rubber or an elastic material synthesized from rubber and plastic. The elastic isolation member 3 composed of rubber or a composite of rubber and plastic is low in cost and has high stability. The elastic isolation member 3 can be composed of heat-resistant and oil-resistant rubber or a composite material of rubber and plastic.

[0033] On the basis of the first embodiment, a plurality of elastic spacers 3 can be provided between two adjacent inner friction plates 1 and two adjacent outer friction plates 2 of the present design. It should be noted that the number of elastic spacers 3 provided between two adjacent inner friction plates 1 and the number of elastic spacers 3 provided between two adjacent outer friction plates 2 can be the same or different; when the number of elastic spacers 3 provided between two adjacent inner friction plates 1 is the same as the number of elastic spacers 3 provided between two adjacent outer friction plates 2, it can ensure that the elastic spacers 3 exert the same force on the inner friction plates 1 and the outer friction plates 2, thereby ensuring a balanced separation distance, thereby reducing the energy loss caused by the contact between the inner friction plates 1 and the outer friction plates 2 in the non-braking state; when the number of elastic spacers 3 provided between two adjacent inner friction plates 1 is different from the number of elastic spacers 3 provided between two adjacent outer friction plates 2, it can ensure the reliable separation between the inner friction plates 1 and the outer friction plates 2 while reducing the manufacturing cost.

[0034] On the basis of Example 1, to ensure that the elastic isolator 3 can more reliably exert force on the inner friction plate 1 or outer friction plate 2, the size of the elastic body is larger than the size of the positioning portion, that is, the size of the elastic body is larger than the size of the positioning hole, so that the elastic isolator 3 can abut against the corresponding inner friction plate 1 or outer friction plate 2, thereby ensuring a sufficient working surface so that the elastic body can reliably drive the outer friction plate 2 or inner friction plate 1 to separate and ensure a gap. At the same time, to ensure that the positioning portion can be reliably embedded in the positioning hole and does not interfere with other positioning portions, the thickness of the positioning portion is no greater than the thickness of the corresponding inner friction plate or outer friction plate.

[0035] Based on the first embodiment, the elastic spacer 3 between two adjacent inner friction plates 1 does not interfere with the outer friction plates 2. In this case, the elastic spacer can be installed in any position. The elastic spacer 3 between two adjacent outer friction plates 2 does not interfere with the inner friction plates. In this case, the elastic spacer can be installed in any position. Preferably, the friction area of ​​the outer friction plate 2 is near the inner region, and the elastic spacer 3 is installed in the outer region of the outer friction plate 2; the friction area of ​​the inner friction plate 1 is near the outer region, and the elastic spacer 3 is installed in the inner region of the inner friction plate 1.

[0036] Based on the first embodiment, the inner friction plates 1 and outer friction plates 2 are sequentially spaced apart, and the elastic spacers 3 between multiple sets of adjacent inner friction plates 1 are coaxially arranged, and the elastic spacers 3 between multiple sets of adjacent outer friction plates 2 are coaxially arranged. The coaxial arrangement of the elastic spacers 3 effectively improves production efficiency and ensures that the forces exerted by the elastic spacers 3 when they push the adjacent inner friction plates 1 or outer friction plates 2 apart are aligned, thereby improving integrity. It should be noted that in actual production, the elastic spacers 3 between multiple sets of adjacent inner friction plates 1 can also be arranged non-coaxially, and the elastic spacers 3 between multiple sets of adjacent outer friction plates 2 can also be arranged non-coaxially.

[0037] In order to improve the overall stability of the elastic isolation member 3 of this design, the elastic body 3.1 and the positioning portion 3.2 are an interconnected whole, thereby ensuring the reliability of the matching between the elastic isolation member 3 and the corresponding inner friction plate 1 and outer friction plate 2.

[0038] It is worth noting that this embodiment does not limit the shape of the positioning hole, which can be circular, square, or triangular, among other shapes. The corresponding positioning portion is also not limited, as long as it can be embedded in the positioning hole to prevent the elastic body from slipping. The shape of the elastic body 3.1 can also be varied, such as cylindrical, spherical, cubic, or triangular prism. Furthermore, each elastic body 3.1 of the multiple elastic spacers 3 can be placed at any suitable location on the same inner friction plate 1 or outer friction plate 2, as long as the elastic body 3.1 has sufficient elasticity and does not interfere with the friction area. Preferably, the multiple elastic spacers 3 on the same inner friction plate 1 or outer friction plate 2 are evenly distributed in an annular pattern.

[0039] Embodiment 2: As shown in FIG5 , an isolation elastic body structure of a friction plate with an energy-saving function includes a plurality of inner friction plates 1 and a plurality of outer friction plates 2 disposed within a brake or clutch. The inner friction plates 1 and outer friction plates 2 are annular with a hole in the middle. The inner friction plates 1 and outer friction plates 2 are arranged in sequence. An elastic isolation member 3 is disposed between two adjacent inner friction plates 1 and two adjacent outer friction plates 2. Each group of adjacent inner friction plates or adjacent outer friction plates includes N elastic isolation members, where N ≥ 2. The elastic isolation member 3 is used to separate two adjacent inner friction plates 1 or two adjacent outer friction plates 2 so that a gap is maintained between the adjacent inner friction plates and the outer friction plates. The elastic isolation member 3 includes an elastic body 3.1 and a positioning portion 3.2. The elastic body 3.1 is located between two adjacent inner friction plates 1 or two adjacent outer friction plates 2. The inner friction plates 1 and outer friction plates 2 are each provided with a positioning hole corresponding to the elastic isolation member 3. The positioning portion 3.2 of the elastic isolation member is embedded in the corresponding positioning hole.

[0040] When the inner friction plates 1, outer friction plates 2, and elastic spacers 3 are used in a brake, the inner and outer friction plates 1 and 2 are sequentially mounted on the brake piston. The ends of the brake piston are equipped with a stopper and a right seal to prevent the inner friction plates from slipping. When in the braking compression state, adjacent inner and outer friction plates 1 and 2 compress the elastic spacers 3, causing them to contact each other and achieve friction braking. When in the non-braking state, the elastic spacers 3 exert a force on the adjacent inner and outer friction plates 1 and 2, forcing them apart. Thus, by providing the elastic spacers 3 between adjacent inner friction plates 1 and between adjacent outer friction plates 2, the separation distance between the inner and outer friction plates 1 and 2 is maintained, effectively reducing friction between the inner and outer friction plates 1 and 2 in the non-braking state, thereby reducing energy loss and friction noise caused by friction in the non-braking state. At the same time, the elastic isolation member 3 of the present design includes an elastic body 3.1 and a positioning portion 3.2. The elastic isolation member 3 can be effectively assembled on the corresponding inner friction plate 1 or outer friction plate 2 through the positioning portion 3.2, so that the elastic isolation member 3 and the inner friction plate 1 or outer friction plate 2 form a whole, effectively improving the stability, thereby avoiding the problem of slippage failure of the adhesive O-ring in the existing design and the deformation of the positioning shaft.

[0041] On the basis of the above, in order to further improve the stability of the elastic isolation member 3, positioning parts 3.2 can be set on both sides of the elastic body 3.1, and the positioning parts 3.2 are embedded in the two adjacent inner friction plates 1 or the two adjacent outer friction plates 2, so as to avoid the elastic isolation member 3 from falling off.

[0042] On the basis of Example 2, the elastic isolation member 3 is a spring with a positioning portion made of metal material, that is, the positioning portion 3.2 and the elastic body 3.1 are both springs made of metal material, wherein the spring size of the elastic body 3.1 is larger than the size of the positioning portion 3.2. The elastic isolation member 3 made of metal material has higher strength and is suitable for high-strength hydraulic brakes, and the restoring force after compression is more reliable.

[0043] On the basis of the second embodiment, a plurality of elastic spacers 3 can be provided between two adjacent inner friction plates 1 and two adjacent outer friction plates 2 of this design. It should be noted that the number of elastic spacers 3 provided between two adjacent inner friction plates 1 can be the same as or different from the number of elastic spacers 3 provided between two adjacent outer friction plates 2. When the number of elastic spacers 3 provided between two adjacent inner friction plates 1 is the same as the number of elastic spacers 3 provided between two adjacent outer friction plates 2, it can ensure that the elastic spacers 3 exert the same force on the inner friction plates 1 and the outer friction plates 2, thereby ensuring a balanced separation distance and reducing the energy loss caused by the contact between the inner friction plates 1 and the outer friction plates 2 in the non-braking state. When the number of elastic spacers 3 provided between two adjacent inner friction plates 1 is different from the number of elastic spacers 3 provided between two adjacent outer friction plates 2, it can ensure the reliable separation between the inner friction plates 1 and the outer friction plates 2 while reducing the manufacturing cost.

[0044] On the basis of the second embodiment, to ensure that the elastic isolator 3 can more reliably exert force on the inner friction plate 1 or outer friction plate 2, the size of the elastic body is larger than the size of the positioning portion, that is, the size of the elastic body is larger than the size of the positioning hole, so that the elastic isolator 3 can abut against the corresponding inner friction plate 1 or outer friction plate 2, thereby ensuring a sufficient working surface so that the elastic body can reliably drive the outer friction plate 2 or inner friction plate 1 to separate and ensure a gap. At the same time, to ensure that the positioning portion can be reliably embedded in the positioning hole and does not interfere with other positioning portions, the thickness of the positioning portion is no greater than the thickness of the corresponding inner friction plate or outer friction plate.

[0045] Based on the second embodiment, the elastic spacer 3 between two adjacent inner friction plates 1 does not interfere with the outer friction plates 2. In this case, the elastic spacer can be installed in any position. The elastic spacer 3 between two adjacent outer friction plates 2 does not interfere with the inner friction plates. In this case, the elastic spacer can be installed in any position. Preferably, the friction area of ​​the outer friction plate 2 is near the inner region, and the elastic spacer 3 is installed in the outer region of the outer friction plate 2; the friction area of ​​the inner friction plate 1 is near the outer region, and the elastic spacer 3 is installed in the inner region of the inner friction plate 1.

[0046] Based on the second embodiment, the inner friction plates 1 and outer friction plates 2 are sequentially spaced apart, and the elastic spacers 3 between multiple sets of adjacent inner friction plates 1 are coaxially arranged, and the elastic spacers 3 between multiple sets of adjacent outer friction plates 2 are coaxially arranged. The coaxial arrangement of the elastic spacers 3 effectively improves production efficiency and ensures that the forces exerted by the elastic spacers 3 when they spread the adjacent inner friction plates 1 or outer friction plates 2 outward are located on the same straight line, thereby improving integrity. It should be noted that in actual production, the elastic spacers 3 between multiple sets of adjacent inner friction plates 1 can also be arranged non-coaxially, and the elastic spacers 3 between multiple sets of adjacent outer friction plates 2 can also be arranged non-coaxially.

[0047] In order to improve the overall stability of the elastic isolation member 3 of this design, the elastic body and the positioning portion 3.2 are integrally formed, thereby ensuring the reliability of the fit between the elastic isolation member 3 and the corresponding inner friction plate 1 and outer friction plate 2.

[0048] It is worth noting that this embodiment does not limit the shape of the positioning hole, which can be circular, square, or triangular, among other shapes. The corresponding positioning portion is also not limited, as long as it can be embedded in the positioning hole to prevent the elastic body from slipping. The shape of the elastic body 3.1 can also be varied, such as cylindrical, spherical, cubic, or triangular prism. Furthermore, each elastic body 3.1 of the multiple elastic spacers 3 can be placed at any suitable location on the same inner friction plate 1 or outer friction plate 2, as long as the elastic body 3.1 has sufficient elasticity and does not interfere with the friction area. Preferably, the multiple elastic spacers 3 on the same inner friction plate 1 or outer friction plate 2 are evenly distributed in an annular pattern.

The objectives of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments.
