Description

Technical Field

[0001] This utility model relates to the field of clutch technology, and in particular to an oil-immersed hydraulic clutch. Background Technology

[0002] The clutch is an important component in the mechanical transmission system of automobiles and other vehicles. It is mainly used to connect and disconnect the power transmission between the engine and the transmission. When the vehicle starts, by gradually engaging the clutch, the engine's power can be smoothly transmitted to the transmission, allowing the vehicle to start slowly. During gear shifting, temporarily disengaging the clutch can interrupt power, facilitate gear switching, and avoid gear collision. When driving, the clutch remains engaged to ensure continuous and effective power transmission, allowing the vehicle to drive normally.

[0003] In existing technologies, some clutches using cable-operated mechanisms are prone to wear and jamming of the cable, which requires a lot of force to operate the clutch, resulting in a poor driving experience and increased driver fatigue. This makes it difficult for users to operate the clutch after long periods of driving. Therefore, an oil-immersed hydraulic clutch was designed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an oil-immersed hydraulic clutch.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An oil-immersed hydraulic clutch includes a flywheel. A clutch housing is fixedly connected to one side of the flywheel. A piston cylinder is disposed inside the clutch housing. The piston cylinder has a cylindrical structure, with the side near the flywheel sealed and a cylindrical piston disposed on the other side. A collar is slidably engaged with the outer circumferential wall of the piston cylinder near the flywheel. Multiple protrusions are fixedly connected at equal intervals to the outer circumferential wall of the piston cylinder near the collar. Multiple grooves that match the protrusions are equally spaced on the inner circumferential wall of the collar. A friction plate is fixedly connected to the outer circumferential wall of the collar by an annular fixing plate, and the friction plate is adapted to the flywheel.

[0007] As a further embodiment of this utility model, a torsional damper is fixedly connected to the inner side of the piston cylinder near the collar. The torsional damper has a circular hole in the middle, and multiple slots are equally spaced around the edge of the circular hole. A gearbox input shaft is rotatably connected to the circular hole, and multiple teeth are fixedly connected at equal distances near the slots on the gearbox input shaft, with the teeth matching the slots.

[0008] As a further embodiment of this utility model, a cylindrical piston is slidably fitted on the inner wall of the piston cylinder on the side away from the flywheel. A sealing disc is rotatably connected to the middle of the cylindrical piston. A circular hole adapted to the gearbox input shaft is opened in the middle of the sealing disc. A rubber sealing ring containing metal is provided at the contact point between the sealing disc and the gearbox input shaft. The sealing mechanism between the sealing disc and the gearbox input shaft is similar to the existing connection method between the gearbox input shaft and the gearbox. The oil inside the gearbox does not affect the rotation of the gearbox input shaft.

[0009] As a further embodiment of this utility model, three Z-shaped fixing blocks are fixedly connected at equal intervals on the edge of the cylindrical piston away from the flywheel. The three Z-shaped fixing blocks are fixedly connected to the same pressure plate on the side closer to the flywheel, and the pressure plate is adapted to the friction plate.

[0010] As a further embodiment of this utility model, a disc stop is fixedly connected to the side of the gearbox input shaft away from the cylindrical piston, and a compression spring is sleeved on the circumferential surface of the gearbox input shaft located between the disc stop and the sealing turntable.

[0011] As a further embodiment of this utility model, the side of the sealing turntable away from the flywheel is fixedly connected to an input oil pipe, and the input oil pipe is connected to the input oil cylinder through a hydraulic oil pipe.

[0012] The beneficial effects of this utility model are as follows:

[0013] This utility model, by employing technologies such as a piston cylinder, cylindrical piston, Z-shaped fixed block, and pressure plate, enables the cylindrical piston to move away from the friction plates via a hydraulic system when the user depresses the clutch pedal. This hydraulic system amplifies the force, effectively solving the problem of difficult operation mentioned in the background technology. Consequently, it enables the clutch to engage and disengage quickly and accurately according to the driver's operating intentions, making the driving process more comfortable and convenient, and improving the vehicle's performance.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Reference Figures 1-4 An oil-immersed hydraulic clutch includes a flywheel 1, a clutch housing 2 fixedly connected to one side of the flywheel 1, a piston cylinder 5 disposed inside the clutch housing 2, a collar 8 slidably engaged with the outer circumferential wall of the piston cylinder 5 near the flywheel 1, a plurality of protrusions 501 fixedly connected at equal intervals to the outer circumferential wall of the piston cylinder 5 near the collar 8, a plurality of grooves 801 adapted to the protrusions 501 being equally spaced on the inner circumferential wall of the collar 8, and a friction plate 802 fixedly connected to the outer circumferential wall of the collar 8 by an annular fixing plate, and the friction plate 802 being adapted to the flywheel 1.

[0022] In this embodiment, a torsional damper 502 is fixedly connected to the inner side of the piston cylinder 5 near the collar 8. The torsional damper 502 has a circular hole in the middle, and multiple slots 503 are equally spaced around the edge of the circular hole. The gearbox input shaft 7 is rotatably connected to the circular hole, and multiple teeth 703 are fixedly connected at equal distances near the slots 503 on the gearbox input shaft 7. The teeth 703 are adapted to the slots 503. The arrangement of the teeth 703 and the slots 503 allows the torsional damper 502 to slide on the gearbox input shaft 7. However, when the torsional damper 502 rotates with the piston cylinder 5 and the collar 8, the gearbox input shaft 7 will definitely rotate.

[0023] In this embodiment, a cylindrical piston 6 is slidably sleeved on the inner wall of the piston cylinder 5 on the side away from the flywheel 1. A sealing turntable 601 is rotatably connected to the middle of the cylindrical piston 6. A round hole adapted to the gearbox input shaft 7 is opened in the middle of the sealing turntable 601, and a rubber sealing ring containing metal is provided at the contact point between the sealing turntable 601 and the gearbox input shaft 7.

[0024] In this embodiment, three Z-shaped fixing blocks 602 are fixedly connected at equal distances on the side edge of the cylindrical piston 6 away from the flywheel 1. The same pressure plate 3 is fixedly connected on the side of the three Z-shaped fixing blocks 602 close to the flywheel 1, and the pressure plate 3 is adapted to the friction plate 802.

[0025] In this embodiment, a disc stop 702 is fixedly connected to the side of the gearbox input shaft 7 away from the cylindrical piston 6, and a compression spring 701 is sleeved on the circumferential surface of the gearbox input shaft 7 located between the disc stop 702 and the sealing turntable 601. By setting the compression spring 701, when the clutch pedal is not pressed, the compression spring 701 pushes the cylindrical piston 6 and the Z-shaped fixing block 602 to press the pressure plate 3 tightly onto the friction plate 802.

[0026] In this embodiment, the side of the sealing turntable 601 away from the flywheel 1 is fixedly connected to the input oil pipe 603, and the input oil pipe 603 is connected to the input oil cylinder through the hydraulic oil pipe.

[0027] Working principle: During normal operation of the engine and transmission, the cylindrical piston 6, along with the Z-shaped fixing block 602 and pressure plate 3, tightly presses the friction plate 802, causing the friction plate 802 to be in a state of static friction with the engine flywheel 1. When it is necessary to separate the engine from the transmission, the clutch pedal drives the input piston inside the input cylinder to move and compress the hydraulic oil. This causes a large amount of hydraulic oil to be input into the piston cylinder 5 through the hydraulic oil pipe, pushing the cylindrical piston 6 away from the flywheel 1. At this time, the compression spring 701 is compressed, and simultaneously, the Z-shaped fixing block 602, along with the pressure plate 3, compresses the piston. The movement of the pressure plate 3 prevents it from pressing the friction plate 802, thus separating the transmission from the flywheel 1. When the friction plate 802 contacts the flywheel 1, kinetic energy is transferred to the piston cylinder 5. Through the torsional damper 502, the kinetic energy is transferred to the transmission input shaft 7. The torsional damper 502 is a current technology in existing clutches, mainly to avoid the rigid connection between the flywheel 1 and the transmission input shaft 7, which would lead to severe wear. At the same time, the piston cylinder 5 is filled with hydraulic oil, which not only provides hydraulic pressure but also lubricates the internal components of the piston cylinder 5. The hydraulic control makes operation easier and smoother.
