Description

Technical Field

[0001] The utility model relates to the technical field of clutches, in particular to a hydraulic clutch with an oil drain hole. Background Art

[0002] The clutch is located in the flywheel housing between the engine and transmission. The clutch assembly is screwed to the rear surface of the flywheel. The clutch's output shaft is the transmission's input shaft. While the car is in motion, the driver can depress or release the clutch pedal as needed to temporarily disengage and gradually engage the engine and transmission, cutting off or transferring power from the engine to the transmission.

[0003] The clutch is usually driven by a hydraulic telescopic rod, but the stroke of the hydraulic telescopic rod is fixed. When the clutch contacts the flywheel, the power of the hydraulic telescopic rod will be overloaded, causing the risk of cylinder explosion. It is impossible to control the oil pressure inside the hydraulic telescopic rod within a reasonable range, which can not only ensure the contact between the clutch and the flywheel, but also achieve safe unloading of the internal oil pressure. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a hydraulic clutch with an oil drain hole.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A hydraulic clutch with an oil drain hole comprises a clutch, a cam shaft fixedly connected to the surface of the clutch, a hydraulic cylinder mounted on one side of the clutch, a moving column slidably connected to the inner wall of the hydraulic cylinder, a driving plate rotatably connected to the inner wall of the moving column, a fixed plate mounted on one side of the driving plate, the driving plate being rotatably connected to the surface of the fixed plate, an avoidance hole being formed on the surface of the driving plate, the cam shaft being mounted inside the avoidance hole, and a pressure relief sensing mechanism fixedly connected to the surface of the moving column;

[0007] The pressure relief sensing mechanism includes a mounting plate fixedly connected to the surface of the moving column, a U-shaped plate fixedly connected to the surface of the mounting plate, a moving block slidably connected to the inner wall of the U-shaped plate, a positioning plate slidably connected to the surface of the moving column, a first pressure sensor fixedly connected to one side of the positioning plate, a deformable plate fixedly connected to one side of the mounting plate, the deformable plate having toughness and being able to bend and deform, and a second pressure sensor fixedly connected to one side of the deformable plate;

[0008] The inner wall of the hydraulic cylinder is fixedly connected with a partition, the inner wall of the partition is rotatably connected with an electric roller, a pressure relief hole is opened on the surface of the electric roller, and the surface of the electric roller is in contact with the inner wall of the partition.

[0009] Preferably, a spring is fixedly connected to the surface of the U-shaped plate, and one end of the spring is fixedly connected to the surface of the moving block.

[0010] Preferably, a connecting plate is fixedly connected to the surface of the moving column, a screw rod is threadedly connected to the inner wall of the connecting plate, and one end of the screw rod is rotatably connected to one side of the positioning plate.

[0011] Preferably, a first one-way valve and a second one-way valve are fixedly connected to the inner wall of the partition.

[0012] Preferably, a swing plate is fixedly connected to the surface of the hydraulic cylinder, and a through hole is opened on the surface of the swing plate.

[0013] Preferably, the second pressure sensor corresponds to the position of the moving block, and the first pressure sensor corresponds to the position of the second pressure sensor.

[0014] The beneficial effects of the utility model are:

[0015] 1. The moving column pushes the clutch under high pressure. The movement of the moving column drives the mounting plate and the U-shaped plate to move as a whole, so that the moving block can contact the surface of the driving plate. At this time, the compression spring becomes shorter for buffering. When one side of the moving block is pressed and contacted with the surface of the second pressure sensor, the deformed plate is driven to bend and deform. The deformed plate after bending and deformation does not contact the surface of the first pressure sensor. At this time, the first pressure sensor will not feel the pressure. When the second pressure sensor feels the pressure, the PLC control is used to stop the moving column and keep it still. The pressure relief hole is blocked by the inner wall of the partition to maintain a high-pressure sealing state. At this time, the clutch friction fits the flywheel and drives the flywheel to rotate.

[0016] 2. During pressure relief, the PLC continues to apply pressure to the moving column. At this time, the friction plate on the flywheel continues to be squeezed. At this time, one side of the deformable plate presses the surface of the first pressure sensor to apply pressure. The first pressure sensor senses and is controlled by the PLC to drive the electric roller to rotate, so that the opening of the pressure relief hole is unobstructed, achieving the effect of flow pressure relief inside the hydraulic cylinder.

[0026] In the present invention, the moving column 8 is provided to cause the driving plate 5 to rotate, the fixed plate 4 is provided to maintain the stability of the rotation of the driving plate 5, the avoidance hole 6 is provided to guide the cam 7 to drive the clutch 1 to move, the U-shaped plate 17 is provided to maintain the stability of the sliding of the moving block 16, and the first pressure sensor 13 is provided. When subjected to pressure, the electric roller 20 is started to rotate to perform a pressure relief operation through PLC control. The first pressure sensor 13 is provided. Through PLC control, the pressure relief hole 24 is fitted with the inner wall of the partition 21 for sealing. The deformation plate 19 is provided. The bending deformation can be generated after being subjected to force. The partition 21 is provided to guide the flowing oil inside the hydraulic cylinder 2.

[0027] A spring 14 is fixedly connected to the surface of the U-shaped plate 17 , and one end of the spring 14 is fixedly connected to the surface of the moving block 16 .

[0028] In the present invention, the spring 14 is provided to drive the movement block 16 to reset and perform compression buffering.

[0029] A connecting plate 10 is fixedly connected to the surface of the moving column 8 , a screw rod 11 is threadedly connected to the inner wall of the connecting plate 10 , and one end of the screw rod 11 is rotatably connected to one side of the positioning plate 12 .

[0030] In the present invention, by providing a screw rod 11 , an operator rotates the screw rod 11 to drive the position of the positioning plate 12 to slide and adjust to adapt to the curvature of the deformable plate 19 .

[0031] A first one-way valve 22 and a second one-way valve 23 are fixedly connected to the inner wall of the partition 21 .

[0032] In the present invention, the first one-way valve 22 and the second one-way valve 23 are provided to prevent the oil from flowing back.

[0033] The surface of the hydraulic cylinder 2 is fixedly connected to a swing plate 3 , and a through hole 15 is opened on the surface of the swing plate 3 .

[0034] In the present invention, by providing the through hole 15 and rotatably mounting it with an external shaft, the hydraulic cylinder 2 can rotate stably when the moving column 8 is in operation.

[0035] The second pressure sensor 18 corresponds to the position of the moving mass 16 , and the first pressure sensor 13 corresponds to the position of the second pressure sensor 18 .

[0036] In the present invention, by arranging the second pressure sensor 18 to correspond to the position of the moving block 16 , the first pressure sensor 13 and the second pressure sensor 18 are also arranged to correspond to each other, so that the first pressure sensor 13 can receive the pressure from the second pressure sensor 18 .

[0037] Working principle: When the hydraulic cylinder 2 is energized, its moving column 8 pushes the clutch 1 under high pressure. The movement of the moving column 8 drives the mounting plate 9 and the U-shaped plate 17 to move as a whole, so that the moving block 16 can contact the surface of the driving plate 5. At this time, the compression spring 14 shortens to buffer. When one side of the moving block 16 is pressed and contacted with the surface of the second pressure sensor 18, the deformed plate 19 is driven to bend and deform. The deformed plate 19 after bending and deformation does not contact the surface of the first pressure sensor 13. At this time, the first pressure sensor 13 will not feel the pressure. When the second pressure sensor 18 feels the pressure, the PLC control is used to stop the moving column 8 and keep it still. The pressure relief hole 24 is closed by the partition 21. The inner wall blocks and maintains a high-pressure sealed state. At this time, the clutch 1 frictionally fits the flywheel and rotates with the flywheel. When pressure relief is required to reset the moving column 8, pressure is continued to be applied to the moving column 8 through the PLC. At this time, the friction plate on the flywheel continues to be squeezed. At this time, one side of the deformable plate 19 presses the surface of the first pressure sensor 13 to apply pressure. The first pressure sensor 13 senses and is controlled by the PLC to drive the electric roller 20 to rotate, so that the opening of the pressure relief hole 24 is not blocked, thereby achieving the effect of flow pressure relief inside the hydraulic cylinder 2, and the moving column 8 is reset under the action of pressure. With the above structure, the oil pressure inside the hydraulic telescopic rod is controlled within a reasonable range, and the safe unloading of the internal oil pressure can be achieved.

Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
