[0038] An input shaft 1, wherein the input shaft 1 is fixedly connected to a clutch outer hub 2;
[0039] A centrifugal deflection part 3, which is arranged on the clutch outer hub 2 and can automatically deflect when rotating at high speed;
[0040] A high-speed coupling part, which is arranged inside the clutch outer hub 2 and can be automatically coupled when the clutch outer hub 2 rotates at a high speed;
[0041] An output sleeve 9, wherein the output sleeve 9 is arranged on the input shaft 1;
[0042] Through the above technical solution, the input end and the output end are controlled by controlling the rotational speed, and a one-way bearing is configured to achieve the torque isolation function between the output and input ends, thereby realizing a clutch with composite purposes, and realizing the dual functions of rotational speed control output combination and torque isolation, so that the weight can be reduced through a reasonable layout, making the present application particularly suitable for realizing friction transmission, rotational speed control output combination, torque isolation and other functions in gear transmission systems, and can be widely used in mechanical transmission fields such as aviation, automobiles, and ships.
[0043] The input shaft 1 is fixedly connected to the clutch outer hub 2 by bolts;
[0044] The centrifugal deflection unit 3 includes an eccentric swing block 301 and a pin 302, and the eccentric swing block 301 is hingedly connected to the clutch outer hub 2 through the pin 302. Through the technical solution, the eccentric swing block 301 has a deflection function through the setting of the pin 302, so that the centrifugal deflection unit 3 can be deflected when the clutch outer hub 2 rotates at a high speed.
[0045] The centrifugal deflection parts 3 are provided in a plurality, and the plurality of centrifugal deflection parts 3 are distributed in an annular shape and are equidistantly arranged on the clutch outer hub 2;
[0046] The high-speed coupling part includes an active friction plate 4 and a driven friction plate 6. A radial groove is provided inside the clutch outer hub 2. The active friction plate 4 and the radial groove of the clutch outer hub 2 are clearance-matched. The active friction plate 4 can slide along the axial direction.
[0047] The clutch outer hub 2 is provided with a driven friction plate 6 inside, and the inner ring of the driven friction plate 6 is provided with spline teeth. The clutch outer hub 2 is provided with a spline core 7 inside, and the spline teeth and the spline core 7 are clearance-matched and can slide axially.
[0048] A release spring 5 is arranged inside the clutch outer hub 2, and the release spring 5 and the clutch outer hub 2 are guided by a pin shaft, and the release spring 5 is arranged between the active friction plate 4 and the driven friction plate 6; the spline core 7 and the output sleeve 9 are coaxially supported by a deep groove ball bearing, and a one-way bearing 8 is arranged inside the clutch outer hub 2, and the one-way bearing 8 is installed between the spline core 7 and the output sleeve 9; the output sleeve 9 and the output flange 10 are fixed by positioning pins and bolts;
[0049] During operation of the present application, the input shaft 1 drives the clutch outer hub 2 to rotate, so that the eccentric block 301 is driven to rotate due to the rotation of the clutch outer hub 2, so that the eccentric block 301 is continuously displaced radially along the hinge axis of the eccentric block 301 as the speed of the clutch outer hub 2 increases, and the cam of the eccentric block 301 is pressed against the active friction plate 4. Since a separation spring 5 is provided between the active friction plate 4 and the driven friction plate 6, the axial pressure generated by the rotation of the eccentric block 301 is balanced with the pressure of the separation spring 5, and the separation spring 5 is gradually compressed as the speed increases. When the gap between the active friction disc 4 and the driven friction plate 6 is compressed and eliminated, the active friction disc 4 can drive the driven friction plate 6 to rotate by friction. The driven friction plate 6 drives the spline core 7 to rotate through the action of the spline teeth. Since the output sleeve 9 uses a deep groove ball bearing to coaxially match the spline core 7, and the one-way bearing 8 is used for one-way support and force transmission, the power input by the input shaft 1 is transmitted to the output sleeve 9 and transmitted by the output flange 10, thereby realizing the function that when the clutch input shaft maintains the maximum speed, the clutch output end will transmit the output with constant torque.
