Abstract

An automatic multi-speed gear system includes an input axle, a first arm coupled at one end with the input axle through bearings that allow for independent rotational movement of the input axle along its longitudinal axis. The first arm is also configured to rotate about the input axle as its pivot. The system also includes a first axle coupled with bearings at the opposing end of the first arm. A first set of gears coupled to the input axle and the first axle transfer the rotational motion of the input axle to the first axle. The system also includes a second arm coupled at one end with bearings to the first axle and at the opposing end to a second axle. The second axle is coupled through a one way bearing to an output axle. A second set of gears coupled to the first axle and the second axle transfer the rotational motion of the first axle to the second axle and a third set of gears coupled to the second axle and the output axle transfer the rotational motion of the second axle to the output axle. The one-way bearing facilitates operation in either a low speed configuration or a high speed configuration.
