The clutch assembly is composed of two friction plates, that is, friction force is applied between the first friction plate 360 and the second friction plate 370, so that the second sleeve 340 drives the corresponding first sleeve 380 to rotate, when the first sleeve 380 drives the corresponding wind shield 320 to rotate to the open position or the closed position to stop rotating, the main shaft 330 continues to drive the second sleeve 340 to rotate, at this time, the wind shield 320 is blocked and can not rotate, that is, a resistance force is provided between the first friction plate 360 and the second friction plate 370, and the resultant force of the resistance force and the friction force between the two friction plates is smaller than the power of the rotation of the main shaft 330, so that the first friction plate 360 and the second friction plate 370 slip with each other, that is, the first friction plate 360 and the second friction plate 370 separate from each other, thereby realizing that no torque is transmitted between the second sleeve 340 and the first sleeve 380.

The second sleeve 340 is pressed by the return spring 342, so that the first friction plate 360 and the second friction plate 370 on the second sleeve 340 are tightly attached, when the wind shield 320 is driven to the opening position or the closing position to stop rotating, the protrusion 371 on the first friction plate 360 is pulled out from the groove 361 on the second friction plate 370, the return spring 342 in the second sleeve 340 is compressed, and when the protrusion 371 corresponds to the groove 361, the elastic force of the return spring 342 pushes the second sleeve 340, so that the protrusion 371 enters the groove 361, and the first friction plate 360 and the second friction plate 370 are tightly attached.
The notch 341 structure provided in the embodiment of the present invention may be directly formed on the outer wall of the second sleeve 340 along the circumferential direction, or may adopt a structure in which, as shown in fig. 8, the notch 341 extends along the axial direction of the second sleeve 340 to an end far from the corresponding first sleeve 380 and penetrates through the end of the second sleeve 340. Compared with the structure, the gap 341 penetrates through the end part of the second sleeve 340, the shifting block 350 can be firstly fixed on the main shaft 330, then the second sleeve 340 is sleeved on the main shaft 330, and the shifting block 350 is fixed on the main shaft 330, when the shifting block 350 is fixed on the main shaft 330, the space is small, so that the installation is inconvenient.
In order to further reduce the processing difficulty, as shown in fig. 8, the shifting block 350 is fixed on a fixing ring 351, then the fixing ring 351 is sleeved on the main shaft 330, the fixing ring 351 is arranged in the second sleeve 340, the fixing ring 351 rotates along with the main shaft 330, and the end of the return spring 350 contacts with the end face of the fixing ring 351. On being fixed in collar 351 with shifting block 350, when the installation, only need in proper order with collar 351, reset spring 342 and second sleeve 340 cover locate main shaft 330 can, more near one-step reduction processing degree of difficulty, improvement work efficiency.
However, this connection method requires a fixed ring 351 to be installed to perform a welding operation, then another component such as the second sleeve 340 is installed, then another fixed ring 351 is installed to perform a welding operation, and then another component such as the second sleeve 340 is installed to perform a welding operation, which results in a complicated overall installation process, and therefore, as shown in fig. 10, the outer wall of the spindle 330 provided in the embodiment of the present invention is provided with a cut surface 331 along the axial direction, and the radial cross section of the inner ring of the fixed ring 351 is the same as the radial cross section of the spindle 330, and has a size suitable for the radial cross section of the spindle 330. The section 331 is axially arranged on the outer wall of the main shaft 330, the section of the inner ring of the fixing ring 351 and the section of the main shaft 330 are in the same shape, namely the inner ring of the fixing ring 351 is also provided with a plane, when the fixing ring 351 is sleeved on the main shaft 330, the plane of the inner ring of the fixing ring 351 is attached to the section 331 on the main shaft 330, so that the fixing ring 351 is prevented from rotating around the main shaft 330, and by using the connecting mode, other fixing process steps are not required to be added during installation, the processing time is saved, and the efficiency is improved.
Preferably, one or more cutting surfaces 331 may be provided on the spindle 330.
