[0013] The following will be described in detail in combination with the accompanying drawings. Figure 1 - Figure 3 The present application will be further described in detail.
[0014] Embodiment:
[0015] A multi-torque clutch gear structure, referring to Figure 1 - Figure 3 , comprising a clutch gear shaft 1, a clutch gear one 2 and a clutch gear two 3 are installed on the clutch gear shaft 1, the clutch gear two 3 is arranged at the rear side of the clutch gear one 2, a plurality of friction plates 4 are arranged inside the clutch gear two 3, an extra and knurled structure 5 is arranged on the clutch gear shaft 1, the friction plates 4 are installed on the clutch gear shaft 1, and the inner diameter of the friction plates 4 is in interference fit with the clutch gear shaft 1, a rotation-stopping key 6 is arranged on one side of the friction plates 4, a thin edge 7 and a thick edge 8 are arranged on the friction plates 4, the thin edge 7 and the thick edge 8 are symmetrically arranged, a clamping groove 9 is arranged inside the rear side of the clutch gear two 3, the plurality of friction plates 4 are arranged inside the rear side of the clutch gear two 3, and the rotation-stopping key 6 of the friction plates 4 is arranged inside the clamping groove 9 of the clutch gear two 3;
[0016] The rotation-stopping key 6 of the friction plates 4 and the clamping groove 9 of the clutch gear two 3 are integrated, the inner diameter of the friction plates 4 is in interference fit with the clutch gear shaft 1, a certain interference force is generated, and friction torque is generated when the clutch gear shaft 1 and the friction plates 4 rotate relative to each other; the front-stage gear drives the clutch gear two 3 to rotate, the clutch gear two 3 and the friction plates 4 drive the clutch gear shaft 1 to rotate, the clutch gear shaft 1 and the clutch gear one 2 are connected and fixed into an integrated whole through the flat position and the knurled structure 5, and the clutch gear one 2 is driven to rotate; when the friction torque generated by the friction plates 4 and the clutch gear shaft 1 is greater than the load torque of the clutch gear 2, that is, the friction torque can overcome the load torque, the clutch is integrated into a whole; when the friction torque generated by the friction plates 4 and the clutch gear shaft 1 is less than the load torque of the clutch gear 2, the friction torque cannot overcome the load torque, and the clutch is separated; the difference in wall thickness of the friction plates 4 is used to generate different torque values in two directions, which can be applied to some special occasions, such as manual opening and closing of the charging port cover, manual opening of the port cover in the closed state, and manual closing of the port cover in the open state.
[0017] When the clutch gear shaft 1 rotates counterclockwise, the friction force generated between the friction plate 4 and the clutch gear shaft 1 is in the opposite direction of the motion, i.e., the friction force is clockwise, the friction force drives the friction plate 4 to lock inward, and the torque becomes larger; when the clutch gear shaft 1 rotates counterclockwise, the friction force generated between the friction plate 4 and the clutch gear shaft 1 is clockwise, the friction force drives the friction plate to expand outward, and the torque becomes smaller; the thin edge 7 and the thick edge 8 of the friction plate 4 are symmetrical in two directions, generating bidirectional equal torque; by adjusting the number, direction and structure of the friction plate 4, the requirement of different torque values can be realized.
[0018] The working principle of the multi-torque clutch gear structure is that when the clutch gear shaft 1 and the friction plate 4 rotate relative to each other, a friction torque is generated; the front-stage gear drives the clutch gear two 3 to rotate, the clutch gear two 3 and the friction plate 4 drive the clutch gear shaft 1 to rotate, the clutch gear shaft 1 and the clutch gear one 2 are connected and fixed into one body through the flat position and the knurled structure 5, and the clutch gear one 2 is driven to rotate; when the friction torque generated between the friction plate 4 and the clutch gear shaft 1 is greater than the load torque of the clutch gear two 2, i.e., the friction torque can overcome the load torque, the clutch is integrated into one whole; when the friction torque generated between the friction plate 4 and the clutch gear shaft 1 is less than the load torque of the clutch gear two 2, the friction torque cannot overcome the load torque, and the clutch is separated.
