Example Embodiment
[0041] Example 1
[0042] Reference attached Figure 5a , 5c , 7, 8a, 8b, 8c, 11:
[0043] The ring crash protection structure for the cone-ring type continuously variable transmission includes a first transmission cone 2, a transmission ring 1. The surface of the first transmission cone 2 is in contact with a surface of the transmission ring 1, and the first transmission cone 2 The small end is provided with a shoulder 21 opposite to the tapered surface 22, and the shoulder 21 has the shape of a revolving body; the transmission ring 1, the shoulder 21, and the tapered surface 22 have the following geometric matching relationship: when the transmission ring 1 When contacting the shaft shoulder 21, there is a first contact point 211 between the transmission ring 1 and the shaft shoulder 21, and there is a second contact point 221 between the transmission ring 1 and the cone surface. The distance between the first contact point 211 and the cone axis P Is the first contact radius r 1...

[0052] Example 2
[0053] Reference attached Figure 6a , 6c , 9, 10a, 10b, 10c, 12:
[0054] The difference between this embodiment and embodiment 1 is: the third transmission component is the second transmission cone 20, the second transmission cone 20 is the input cone, the transmission ring 1 is sleeved on the second transmission cone 20, A transmission cone 30 is an output cone; the cone generatrix of the first transmission cone 30 is parallel to the cone generatrix of the second transmission cone 20. The taper of the first transmission cone 30 and the second transmission cone 20 can be different, such as Figure 6a Shown; when the taper of the two is the same, such as Figure 6c As shown, the cone axes P of the first transmission cone 30 and the second transmission cone 20 are parallel to each other, and the large end and the small end are arranged oppositely.
[0055] On the shaft section made through the cone axis P, the tangent 3111 of the generatrix 312 of the shoulder 31 ...
Example Embodiment
[0062] Example 3
[0063] Reference Figure 5b , 7 , 8a, 8b, 8c, 11, the difference between this embodiment and Embodiment 1 is: the third transmission component is a cylinder, and the rest are the same.
[0064] In addition, the third transmission component may also be a rotating body other than a cylinder and a cone.
[0065] The working process is similar to that of Example 1.
