Description
Technical Field
[0001] The utility model relates to the technical field of ship equipment, in particular to a clutch engagement buffering structure and a marine clutch. Background Art
[0002] The marine hydraulic wet clutch is an important part of the ship power system. The clutch drives the piston to press the friction plates through hydraulic pressure, so as to realize its own engagement function. The specific process is as follows: The operator controls the hydraulic oil to enter the piston cavity from the external oil cylinder. The piston drives the thrust plate to move together under the oil pressure of the hydraulic oil. The thrust plate will push the inner and outer friction plates to make the friction plates in a pressed state. At this time, the clutch housing and the friction plate seat form a whole, so as to drive the output shaft to rotate and realize the forward or backward movement of the ship; When the ship needs to stop, the operator stops supplying hydraulic oil, and the piston will reset under the action of the back pressure spring, so as to realize the disengagement of the clutch.
[0003] In the process of the conventional clutch engaging, the thrust plate of the piston will directly abut against the friction plate under the action of the oil pressure, which will cause a large impact on the friction plate. The engagement impact will destroy the smoothness of the clutch during engagement, and at the same time, it will also generate a large amount of noise. And the long-term engagement impact will have an irreversible impact on the service life of the clutch. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a clutch engagement buffering structure and a marine clutch, which can buffer the impact during engagement, so as to ensure a gentle engagement.
[0005] To achieve the above purpose, the utility model adopts the following technical solutions:
[0006] The utility model provides a clutch engagement buffering structure, which is arranged between the piston and the friction plate and includes:
[0007] A push plate, which is connected to the piston and can move along a first direction under the drive of the piston;
[0008] A push block, which is arranged on the push plate. A first elastic member is arranged between the push block and the push plate. The push block is used to abut against the friction plate. The first elastic member is configured to make the push block have a movement tendency of always moving away from the push plate along the first direction. The push block is used to abut against the friction plate;
[0009] A second elastic member is arranged between the piston and the fixed seat of the input shaft. The second elastic member is configured to make the piston have a movement tendency of always moving away from the friction plate along the first direction.
[0010] Preferably, a plurality of push blocks are provided.
[0011] Preferably, the push plate is in an annular structure, and a plurality of the push blocks are uniformly arranged on the push plate in the circumferential direction.
[0012] Preferably, one side of the push plate close to the friction plate is a connection and arrangement surface for pushing and pressing the friction plate. An avoidance hole is formed in the connection and arrangement surface, the first elastic member is arranged in the avoidance hole, and the push block abuts against the first elastic member.
[0013] The avoidance hole is used to accommodate the push block, so that when the push block abuts against the friction plate, the end surface of the push block can be flush with the connection and arrangement surface.
[0014] Preferably, the push block includes a rod portion and a head portion connected to each other. The rod portion passes through the first elastic member, and the head portion abuts against the first elastic member along the first direction.
[0015] Preferably, the clutch connection and arrangement buffer structure further includes a limit stop block arranged in the avoidance hole. The limit stop block can abut against the push block and is configured to prevent the push block from falling off the avoidance hole.
[0016] Preferably, the push plate is bolted to the piston.
[0017] A marine clutch includes a piston, a friction plate, a fixed seat, a second elastic member, and the above-mentioned clutch connection and arrangement buffer structure.
[0018] The beneficial effects of the present invention are as follows:
[0019] For the clutch connection and arrangement buffer structure provided by the present invention, the push plate is connected to the piston, and the push block is arranged on the push plate. The push plate can move along the first direction under the drive of the piston, so as to drive the push block to abut against the friction plate along the first direction, and then push and press the friction plate to realize the connection and arrangement of the clutch. Since a second elastic member is arranged between the piston and the fixed seat of the input shaft, the second elastic member can apply an elastic force to the piston to make the piston have a movement tendency away from the friction plate. Then when the hydraulic oil is no longer used to drive the piston, the piston can be reset under the drive of the second elastic member, so that the push plate and the push block are both separated from the contact with the friction plate, thereby realizing the disengagement of the clutch. Since a first elastic member is arranged between the push block and the push plate, when the push block pushes and presses the friction plate under the drive of the push plate, the first elastic member and the second elastic member act together to buffer the pressure on the piston, reduce the connection and arrangement impact on the friction plate, and play an effective role in protecting the friction plate, thereby prolonging the service life of the clutch.
[0020] The marine clutch provided by the present utility model includes a piston, a friction plate, a fixed seat, and a second elastic member, and adopts the above clutch engagement buffer structure, which can reduce the impact during engagement, the engagement is gentle, stable, and the engagement noise is small.

In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.
[0037] Such as Figure 1 And Figure 2As shown in the figure, the present utility model provides a clutch engagement and disengagement buffering structure, which is arranged between the piston 100 and the friction plate 200. The clutch engagement and disengagement buffering structure includes a push plate 1 and a push block 2. The push plate 1 is connected to the piston 100 and can move along the first direction under the drive of the piston 100. The push block 2 is arranged on the push plate 1, and a first elastic member 3 is arranged between the push block 2 and the push plate 1. The push block 2 is used to abut against the friction plate 200, and the first elastic member 3 is configured to make the push block 2 have a movement tendency to always move away from the push plate 1 along the first direction. The push block 2 is used to abut against the friction plate 200. A second elastic member 300 is arranged between the piston 100 and the fixed seat 400 of the input shaft, and the second elastic member 300 is configured to make the piston 100 have a movement tendency to always move away from the friction plate 200 along the first direction. In this embodiment, the first direction is the axial direction of the input shaft. The push plate 1 is connected to the piston 100, and the push block 2 is arranged on the push plate 1. The push plate 1 can move along the first direction under the drive of the piston 100, so as to drive the push block 2 to abut against the friction plate 200 along the first direction, and then push the friction plate 200 to realize the engagement and disengagement of the clutch. Since a second elastic member 300 is arranged between the piston 100 and the fixed seat 400 of the input shaft, the second elastic member 300 can apply an elastic force to the piston 100 to make the piston 100 have a movement tendency to move away from the friction plate 200. When the piston 100 is no longer driven by hydraulic oil, the piston 100 can be reset under the drive of the second elastic member 300, so that the push plate 1 and the push block 2 are both separated from the contact with the friction plate 200, thereby realizing the disengagement of the clutch. Since a first elastic member 3 is arranged between the push block 2 and the push plate 1, when the push block 2 pushes the friction plate 200 under the drive of the push plate 1, the first elastic member 3 and the second elastic member 300 act together to buffer the pressure on the piston 100, reduce the engagement and disengagement impact received by the friction plate 200, and effectively protect the friction plate 200, thereby extending the service life of the clutch.
[0038] Further, as Figure 3 shown, a plurality of push blocks 2 are arranged. In this embodiment, a plurality of push blocks 2 are arranged on the push plate 1, and the plurality of push blocks 2 act together to buffer the impact on the piston 100, thereby further improving the smoothness of the clutch engagement and disengagement.
[0039] Specifically, as Figure 1 and Figure 3 shown, the push plate 1 is of an annular structure, and a plurality of push blocks 2 are uniformly arranged on the push plate 1 in the circumferential direction. In this embodiment, the friction plate 200 is of an annular structure and is sleeved on the output shaft. The push plate 1 is also of an annular structure to better match with the friction plate 200. Specifically, a plurality of push blocks 2 are uniformly arranged on the push plate 1 in the circumferential direction, ensuring the smooth and uniform force on the friction plate 200, thereby improving the stability of the engagement and disengagement.
[0040] Further, one side of the push plate 1 close to the friction plate 200 is a connection surface for pushing the friction plate 200. An avoidance hole 11 is provided on the connection surface, and the first elastic member 3 is disposed in the avoidance hole 11. The push block 2 abuts against the first elastic member 3. The avoidance hole 11 is used to accommodate the push block 2 so that when it abuts against the friction plate 200, the end surface of the push block 2 can be flush with the connection surface. In this embodiment, the avoidance hole 11 is provided on the push plate 1, the first elastic member 3 is fixed in the avoidance hole 11, and the push block 2 is disposed on the first elastic member 3. Specifically, before the push block 2 abuts against the friction plate 200, the push block 2 protrudes from the connection surface in the first direction. Subsequently, the push block 2 moves close to the friction plate 200 in the first direction driven by the push plate 1. The push block 2 will first push the friction plate 200 with the elastic force of the first elastic member 3. As the piston 100 drives the push plate 1 to continuously approach the friction plate 200 in the first direction, the first elastic member 3 will also be continuously compressed, and the push block 2 will also be continuously pressed into the avoidance hole 11 until the end surface of the push block 2 is flush with the connection surface of the push plate 1. At this time, the connection surface will push the friction plate 200 and finally complete the clutch connection. During this process, the elastic force of the first elastic member 3 pushing the friction plate 200 is less than the pressure of the connection surface directly pressing the friction plate 200. Therefore, the first elastic member 3 plays a good buffering role for the pressure of the connection surface.
[0041] Specifically, as Figure 2 shown, the push block 2 includes a connected head 22 and a rod portion 21. The rod portion 21 is inserted through the first elastic member 3, and the head 22 abuts against the first elastic member 3 in the first direction. In this embodiment, the outer diameter of the rod portion 21 is smaller than the outer diameter of the head 22. The first elastic member 3 is a spring, one end of which is fixed in the avoidance hole 11. The rod portion 21 of the push block 2 is inserted into the internal space formed by enclosing the first elastic member 3, and the head 22 of the push block 2 abuts against the other end of the first elastic member 3 in the first direction. The outer periphery of the rod portion 21 is in contact with the first elastic member 3, so as to limit the displacement of the push block 2 to ensure that the push block 2 always moves in the first direction.
[0042] Specifically, as Figure 2 shown, the clutch connection buffering structure further includes a limit stop block 4. The limit stop block 4 is disposed in the avoidance hole 11. The limit stop block 4 can abut against the push block 2 and is configured to prevent the push block 2 from falling off the avoidance hole 11. In this embodiment, a convex platform is provided on the outer peripheral surface of the head 22 of the push block 2. The limit stop block 4 is fixed in the avoidance hole 11, and the convex platform of the head 22 can abut against the limit stop block 4 in the first direction, thereby preventing the push block 2 from coming out of the avoidance hole 11.
[0043] Further, as Figure 3 shown, the push plate 1 is bolted to the piston 100. In this embodiment, the push plate 1 is bolted to the piston 100, which is convenient for disassembly and assembly.
[0044] This embodiment also provides a marine clutch, which includes a piston 100, a friction plate 200, a fixed seat 400, a second elastic member 300, and the above-mentioned clutch engagement buffer structure. This marine clutch has a simple structure and reliable operation, can reduce the impact during engagement, has a smooth and quiet engagement process.
[0045] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
