| 发明名称 | Variable transmission system | ||
| 摘要 | An example variable transmission system is provided. As an example, a variable transmission system may include a frame, an output hub coupled to the frame, a first linear actuator coupled to the frame, and a second linear actuator coupled to the frame. The variable transmission system may also include a tension-bearing element positioned around the output hub. A first end of the tension-bearing element may be coupled to the first linear actuator, and a second end of the tension-bearing element may be coupled to the second linear actuator. The tension-bearing element may include a variable stiffness profile such that a transmission ratio of the output hub may be adjusted based on a position of the second linear actuator relative to the output hub. | ||
