Abstract
A variable-ratio transmission device for use in connection with a machine, such as a vehicle, comprising a stepless speed change gear with a continuously variable-ratio over an extremely wide range of speeds.
Claims21
A variable-ratio transmission device for use in connection with a machine, the transmission device having a reduction ratio and comprising:
- a first support assembled idle on a second hollow shaft with a slanted axis connected to a motor means;
- a plurality of teeth or rollers on the first support;
- a wheel with a first series of teeth or rollers configured to connect to the machine;
- and
- means for axially sliding the first support, in order to change the reduction ratio of transmission device;
- where rotation of the second hollow shaft causes the first support to perform an orbital movement, thereby causing the teeth or rollers on the first support to engage the teeth on the wheel.

A variable-ratio transmission device for use in connection with a machine, the transmission device comprising:
- a support shaft having an axis;
- a second hollow shaft rotatingly assembled on the support shaft;
- a first support assembled on the second hollow shaft, and configured to rotate around a slanted axis with respect to the axis of the support shaft;
- a plurality of teeth or rollers arranged in a circular series on the first support;
- a wheel assembled idle on the support shaft;
- a first series of teeth or rollers on the wheel adapted to be engaged by the plurality of teeth or rollers on the first support;
- means to connect the wheel to the machine to which motion is transmitted;
- and
- means for axially sliding the first support or the wheel with respect to the support shaft;
- where rotation of the second hollow shaft causes the first support to perform an orbital movement, thereby causing the teeth or rollers on the first support to engage the teeth on the wheel.
