Detailed Description

The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the invention easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the invention.

Referring to fig. 1, an embodiment of the present invention includes:

a spherical continuously variable transmission, comprising: the belt type continuously variable transmission mainly solves the problems of complex structure, low reliability and weak transmission force of the cone ring continuously variable transmission.

The adopted technical scheme is that different rotating speeds can be obtained by utilizing the principle that linear speeds at different latitudes are different when a ball rotates, and the driving wheels and the driven wheels are respectively positioned at different latitudes of the spherical friction wheel. Due to the characteristics of the sphere, when the angle of the motion axis of the spherical wheel is changed, the distance between the main driving wheel and the auxiliary driving wheel is unchanged, namely the main driving wheel and the auxiliary driving wheel are fixedly arranged, the position of a contact point between the main driving wheel and the auxiliary driving wheel is changed due to the change of the angle of the axis of the spherical wheel, and the linear speed of the transmission is changed. Namely, the stepless speed change can be realized by controlling the rotating shaft angle of the ball wheel.
