Description

Technical Field

[0001] This utility model relates to a clutch, and more particularly to a toothed clutch. Background Technology

[0002] The clutch is located inside the flywheel housing between the engine and the transmission. The clutch is fixed to the rear surface of the flywheel with fasteners, and the output shaft of the clutch is the input shaft of the transmission.

[0003] The clutch is a common component in mechanical transmission, which can separate or engage the transmission system at any time. In working environments that require frequent separation or engagement and high torque, conventional clutches, due to their friction plate transmission method, generally have low driving torque, high friction plate temperature, and frequent engagement and disengagement, making the friction plates prone to wear and slippage, requiring frequent replacement and resulting in relatively high costs. Furthermore, traditional friction plate clutches are prone to jerking and slippage, resulting in a delay in engine torque transmission. The slow response speed when the friction plates are pressed can easily cause noticeable jerking and shaking of the vehicle body when the pedal is released during gear shifting, which is not conducive to smooth and stable driving. Therefore, friction plate clutches are very unsuitable for working conditions that require smooth power transmission.

[0004] Chinese utility model patent CN 202971666 U discloses a one-way friction clutch. This clutch is characterized by a flywheel connected to a friction plate, friction plate rivets fixing the friction plate to the outer edge of the driven disc hub, a shock absorber spring connected to the driven disc hub, shock absorber damping plates symmetrically mounted on one side of the shock absorber spring, a driven plate mounted to the clutch output shaft spline by rivets, a pressure plate tightly connected to the driven plate, a clutch cover mounted on top of the pressure plate by bolts, and a gasket installed between the bolts and the clutch cover; a support ring is provided inside the clutch cover, one end of a diaphragm spring is riveted to the clutch cover, and the other end is fixed to the pressure plate by screws, a release bearing device is mounted on a bearing guide sleeve, and one end of a wedge-shaped one-way clutch is fixed to the clutch output shaft, while the other end is fixed to the gearbox body by a mounting bracket. This clutch, by pressing the friction plate with a spring, results in slow response speed and noticeable vehicle jerking. Under high resistance conditions, it is prone to friction plate slippage, which is detrimental to the smooth transmission of force. Utility Model Content

[0005] This invention aims to overcome the shortcomings of the prior art by providing a toothed clutch that offers smooth power transmission, high torque, no slippage, and suitability for heavy-duty environments, thus meeting the requirements for smooth driving, no slippage, and high torque transmission.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: This toothed clutch includes a housing, a support base fixed inside the housing, a first transverse hole on the support base, a drive turntable rotatably connected to the first transverse hole, a drive shaft mounted on the drive turntable, a first gear plate fixed to the right end of the drive turntable, an output turntable rotatably connected to the housing at the opposite position of the drive turntable, a second transverse hole on the output turntable, a rotating block rotatably connected to the second transverse hole, an output shaft mounted on the rotating block, a second gear plate at the opposite position of the first gear plate, a circular boss fixed to the left end of the output turntable, a set of semi-circular guide blocks evenly distributed along the center of the circular boss fixed on the outer contour of the circular boss, a set of semi-circular guide holes respectively inserted and engaged with each semi-circular guide block on the second gear plate, and a set of concave holes evenly distributed along the center of the second gear plate and cross-sections smaller than the concave holes at the left end of the second gear plate. The perforation and concave hole are coaxially arranged. Each perforation is equipped with a cylindrical rod fastened to the output turntable. Each cylindrical rod has a baffle with a cross-section larger than the cylindrical rod fixed to its left end. A compression spring is installed between each baffle and the end face of each concave hole and is sleeved on the cylindrical rod. The outer contour of the second transverse hole is provided with an annular groove that is opened on the output turntable and passes through the second transverse hole. A set of first fixing blocks are fixed on the annular groove and are evenly distributed along the center of the annular groove. The left and right sides of each first fixing block are first conical surfaces in the shape of "V". A set of second fixing blocks are fixed on the outer contour of the rotating block and are evenly distributed along the center of the rotating block. The left and right sides of each second fixing block are second conical surfaces in the shape of "V". An arc block is fixed on the opposite side of each pair of adjacent first fixing blocks and second fixing blocks. A first compression spring is sleeved between each pair of adjacent arc blocks. An electromagnet is fixed to the support base on the left side of the first gear plate.The support base, first transverse hole, drive disc, first gear disc, and drive shaft here function to transmit power output from the power source (such as an engine). The rotating block, output disc, second transverse hole, output shaft, annular boss, semi-circular guide block, second gear disc, semi-circular guide hole, cylindrical rod, baffle, and compression spring here function to transmit power output from the power source, thus facilitating clutch engagement and disengagement. The annular groove, first fixed block, first conical surface, second fixed block, second conical surface, arc block, and first compression spring here function to provide a buffering effect at the moment of contact between the second and first gear discs, thereby preventing tooth wear between the two discs and extending the clutch's service life. Longer; the function of the electromagnet here is that, by using electromagnetic means, when the electromagnet is energized, the first gear plate generates a strong tooth force, thereby attracting the second gear plate to move towards the first gear plate and touch it together, thus enabling the rapid transmission of torque to the power source. This is especially suitable for working conditions that require frequent engagement and disengagement of the clutch; the function of the first cone surface, the second cone surface, and the arc block here is that when the output turntable rotates, the first compression spring will be compressed along the arc direction. When the first compression spring is compressed, it will not deviate, and the energy storage characteristics of the first compression spring are better; the function of the semi-circular guide block and the semi-circular guide hole here is that it can both move the second gear plate and drive the output turntable to rotate together when the second gear plate rotates.

[0007] Further improvements include the addition of a first self-lubricating layer on the contour surface of each semi-circular guide hole. The function of this first self-lubricating layer is to minimize frictional resistance during the movement of the second gear disc and to prevent jamming. This first self-lubricating layer is made of tin bronze.

[0008] To further improve the clutch, a wear-resistant layer made of cobalt-based alloy is applied to the surface of each tooth of the first gear disc and the surface of each tooth of the second gear disc. The purpose of this wear-resistant layer is to increase the service life of the clutch and prevent wear, denting, or damage to the clutch teeth.

[0009] Further improvements include the addition of a pair of opposing mounting plates fixed to the housing, each with a set of mounting holes along its center. The purpose of these mounting plates and holes is to facilitate the convenient and secure installation of the clutch.

[0010] The beneficial effects of this utility model are:

[0011] 1) The support base, the first transverse hole, the drive turntable, the first gear plate, and the drive shaft can be used to transmit the power output from the power source;

[0012] 2) The rotating block, output turntable, second transverse hole, output shaft, annular boss, semi-circular guide block, second gear plate, semi-circular guide hole, cylindrical rod, baffle, and compression spring can be used to transmit the power output from the power source, thereby facilitating the clutch engagement and disengagement operation;

[0013] 3) The annular groove, the first fixed block, the first conical surface, the second fixed block, the second conical surface, the arc block, and the first compression spring provide a buffering effect at the moment the second gear plate contacts the first gear plate, thereby preventing tooth grinding between the second and first gear plates and extending the service life of the clutch. The electromagnet's function here is to generate a strong tooth force on the first gear plate when it is energized, thereby attracting the second gear plate to move towards the first gear plate and make contact, thus enabling rapid torque transmission to the power source.

[0014] 4) Electromagnets can be used to generate strong tooth force on the first toothed plate when the electromagnet is energized, thereby attracting the second toothed plate to move towards the first toothed plate and make contact with it. This allows for the rapid transmission of torque to the power source, which is especially suitable for applications that require frequent engagement and disengagement of the clutch.

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] Referring to the attached diagram: This toothed clutch includes a housing 1, a support base 2 fixed inside the housing 1, a first transverse hole 2-1 on the support base 2, a drive disc 3 rotatably connected to the first transverse hole 2-1, a drive shaft 4 mounted on the drive disc 3, a first gear 3-1 fixed to the right end of the drive disc 3, and an output disc 5 rotatably connected to the drive disc 3 within the housing 1 at a corresponding position. The output disc 5 has a second transverse hole 5-1, a rotating block 6 rotatably connected to the second transverse hole 5-1, and an output shaft 7 mounted on the rotating block 6. A second gear disk 8 is positioned opposite to the first gear disk 3-1. A circular boss 5-2 is fixed to the left end of the output turntable 5. A set of semi-circular guide blocks 5-2a are fixed on the outer contour of the circular boss 5-2, evenly distributed along the center of the circular boss 5-2. A set of semi-circular guide holes 8-1 are opened on the second gear disk 8, which are respectively inserted and matched with each semi-circular guide block 5-2a. A set of concave holes 8-2 and through holes 8-3 with a cross-section smaller than the concave holes 8-2 are opened on the left end of the second gear disk 8. 8-3 are coaxially arranged, and each through hole 8-3 is provided with a cylindrical rod 9 fastened to the output turntable 5. The left end of each cylindrical rod 9 is fixed with a baffle 10 with a cross-section larger than the cylindrical rod 9. A compression spring 11 sleeved on the cylindrical rod 9 is installed between each baffle 10 and the end face of each concave hole 8-2. The outer contour of the second transverse hole 5-1 is provided with an annular groove 5-3 that is opened on the output turntable 5 and passes through the second transverse hole 5-1. A set of first fixing blocks 12 are fixed on the annular groove 5-3 and evenly distributed along the center of the annular groove 5-3. The left and right sides of the fixed block 12 are V-shaped first conical surfaces 12-1. A set of second fixed blocks 6-1 are fixed on the outer contour of the rotating block 6 and evenly distributed along the center of the rotating block 6. The left and right sides of each second fixed block 6-1 are V-shaped second conical surfaces 6-1a. A circular arc block 13 is fixed on the opposite side of each of the two adjacent first fixed blocks 12 and the second fixed blocks 6-1. A first compression spring 14 is sleeved between each of the two adjacent circular arc blocks 13. An electromagnet 15 is fixed on the left side of the first gear plate 3-1 at the support base 2.

[0024] A first self-lubricating layer 8-1a is provided on the contour surface of each semi-circular guide hole 8-1.

[0025] A wear-resistant layer a made of cobalt-based alloy material is provided on each tooth surface of the first tooth disk 3-1 and on each tooth surface of the second tooth disk 8.

[0026] A pair of oppositely arranged mounting plates 16 are fixed on the housing 1, and a set of mounting holes 16-1 are opened on the two mounting plates 16 along the center of the mounting plates 16.

[0027] The working principle of this utility model is as follows: When it is necessary to quickly transmit torque to the clutch, it is only necessary to activate the electromagnet 16 to generate a strong magnetic force, which in turn causes the first gear plate 3-1 to generate a strong magnetic force. At this time, the magnetic force quickly attracts the second gear plate 8, causing the teeth on the second gear plate 8 to contact and engage with the teeth on the first gear plate 3-1. At the same time, each compression spring 11 is compressed and stores energy. At the instant the teeth on the second gear plate 8 engage with the teeth on the first gear plate 3-1, the power output by the engine is transmitted to the drive turntable 3 through the drive shaft 4 to rotate, and then quickly transmitted to the second gear plate 8 through the first gear plate 3-1. Thus, the output turntable 5 rotates through the semi-circular guide hole 8-1 and the semi-circular guide block 5-2a. To avoid the teeth on the second gear plate 8 from rubbing against the teeth on the first gear plate 3-1, the first fixing block 12 will rotate quickly and compress the first compression spring 14. Only when the arc block 13 on the first fixed block 12 touches the arc block 13 on the second fixed block 6-1 will the torque generated by the engine drive the output shaft 7 to output power. Through the strong torque buffer of the first compression spring 14, at this time, the teeth on the second gear plate 8 and the teeth on the first gear plate 3-1 are completely locked together, so that the torque output by the engine can be 100% transmitted without slippage. The power output is strong and smooth, and it is especially suitable for use in heavy-duty working conditions. When it is necessary to disengage the clutch and stop outputting power, it is only necessary to turn off the electromagnet 16, so that the first gear plate 3-1 loses its magnetism. Through the elastic restoring force of each compression spring 11, the second gear plate 8 quickly disengages from the first gear plate 3-1, thereby quickly cutting off the power output. This utility model has smooth force transmission, large torque transmission, no slippage, and is suitable for heavy-duty environments, and is worth promoting and applying.
