That is, when the input shaft 11 rotates, the rotation of the input shaft yoke can cause the ball 14 to push the sliding drive plate i 3 with its centrifugal force to slide along the driving plate 6 in the axial direction 20, and the transmission disk spring 18 can have its elastic force. The thrust sliding drive disc 17 is axially slid along the output shaft 15, so that the drive disc 12, the slide drive disc 13, the drive disc 16, and the slide drive disc 17 can clamp the drive belt 19, causing the drive belt 19 to follow the rotation 'and The drive belt 19 moves up and down due to the difference in rotational speed, and the radius ratio of 8 1292379 is used to change the drive disc group 1 〇丨 and the drive disc group 丨〇 2 to achieve stepless shifting. 7 ′ This collar 7 is with a clearance. The drive disc is convex 6 and includes a set of ring-fit (loose) loops on the drive disc projection 6. 5 10 15 20 t In the present embodiment, the outer circumference of the collar 7 is sleeved with the ball bearing 2, and the driving sleeve of the sleeve 7 and the ball shaft is located between the driving plate 12 and the sliding driving plate η. Up and adjacent to the drive plate 12, while the 'sleeve 7 and the ball bearing 2 are the radial top drive belt 19, causing a transmission between the drive belt drive plate 12 and between the drive belt 19 and the slide drive plate 13. gap. In detail, the sleeve 7 and its design with the clearance fit around the drive disc protrusion 6 are designed such that when the vehicle engine 3 is at idle (low speed), the slide drive disc 13 will face away The drive plate 12 is slidably biased on the drive plate to cause an increase in the distance between the slide drive plate 13 and the drive plate 12. At this time, the drive belt 19 is moved downward, when the drive belt 19 is moved to a certain height. The transmission belt 19 is stopped on the collar 7 and the ball bearing 2, and when the sliding drive plate 13 continues to slide back toward the drive plate 12, between the transmission belt 19 and the driving core, and the transmission belt 19 A gap can be generated between the sliding driving discs 13, and by the generation of the gap, the driving disc 12 and the sliding driving disc 13 do not generate clamping force with the driving belt 19, so the transmission belt 19 does not (4) drive with The disk 12 rotates with the sliding drive disk 13 'that is, the output shaft, so there is not enough friction to generate the rotation. Thereby, the rotational power of the vehicle engine 3 can be interrupted by the above-described gaps. Thus, the function of the conventional clutch can be replaced, and the weight of the vehicle engine 3 can be reduced, and the cost can be reduced thereby. 9 1292379 Please refer to FIG. 3 is a cross-sectional view showing a second preferred embodiment of the present invention, the main structure of which is the same as that of the first preferred embodiment described above, except that the outer sleeve of the collar 7 is provided with a needle bearing 4 When the collar 7 and the needle bearing 4 are assembled, they are adjacent to the driving plate 12, and the design can also achieve the various functions described in the first preferred embodiment. The collar 7 of each of the above embodiments is preferably used with the ball bearing 2 and the needle bearing 4, respectively. If only the collar 7 is used, the collar 7 is fitted with a clearance fit to the drive disc. 6, so the drive disk convexity 6 does not drive the collar 7 to rotate, that is, only the collar 7 can be used to achieve the effect of the present invention. <3> The above-described embodiments are merely examples for convenience of description, and the scope of the claims should be construed as being limited to the above embodiments.
