Abstract
A pawl for controlling the rotation of a gear in a planetary gear mechanism. The pawl includes a nose and first and second pivot axes. The nose is engageable with the gear. The pawl is rotatable about the first pivot axis between a first mode permitting rotation of the gear in a first direction and a second direction and a second mode preventing rotation of the gear in the first direction. The pawl is rotatable about the second pivot axis to permit rotation of the gear in the second direction while the pawl is the second mode.
Claims17
A pawl for controlling the rotation of a gear of a planetary gear mechanism, the pawl comprising:
- a nose engageable with the gear;
- a first pivot axis about which the pawl is rotatable between a first mode permitting rotation of the gear in a first direction and a second direction and a second mode preventing rotation of the gear in the first direction;
- and
- a second pivot axis about which the pawl is rotatable to permit rotation of the gear in the second direction while the pawl is in the second mode.
A control system for a bicycle planetary gear mechanism having a plurality of gears, the control system comprising:
- a pawl including:
- a nose engageable with the gear,
- a first pivot axis about which the pawl is rotatable between a first mode permitting rotation of the gear in a first direction and a second direction and a second mode preventing rotation of the gear in the first direction, and
- a second pivot axis about which the pawl is rotatable to permit rotation of the gear in the second direction while the pawl is in the second mode;
- a first seat for the pawl;
- and
- a shift actuator for positioning the pawl between the first and second modes.
