Title:
SYSTEMS AND METHODS FOR SELF-PROPELLED GARDEN MACHINES
Document Type and Number:
WIPO Patent Application WO/2022/236734
Kind Code:
A1
Abstract:
Systems and methods which provide motive forces with respect to various apparatuses using self-engaging/disengaging transmission configurations are described. An autonomous-state transmission (210) may comprise a transmission unit configured to autonomously engage and disengage transmission of power from a driving input member (201) to a driven output member (202) without utilization of external gearing or additional mechanical feedback. Embodiments of an autonomous-state transmission may utilize various roller-ramp clutch configurations in communication with override control for disengaging the roller-ramp clutch (220). The override control (221) may implement various configurations of a skidding mechanism for facilitating engaging and/or disengaging the roller-ramp clutch (220). According to some examples, motion of the driving input member (201) and/or driven output member (202) is utilized for override force detection and providing override control (221) with respect to the autonomous-state transmission (210). Embodiments of an autonomous-state transmission (210) may be bidirectionally operative to autonomously engage and disengage transmission of power from a driving input to a driven output.
