Rail handbrake with prolonged release |
摘要 |
A hand brake actuator for a rail car has a rotary input connected to a rotary output by a transmission including a clutch and a ratchet wheel and pawl, a declutching mechanism for disengaging the clutch in a declutched position of the declutching mechanism, and a release handle with a first cam which drives the declutching mechanism to the declutched position when the release handle is moved from an apply position to a release position. A second cam is biased in a first direction to engage and retain the declutching mechanism in a declutched position after the release handle is removed from the release position. A follower is connected to the second cam and is responsive to the rotation of the input in an apply direction to rotate the second cam in a second direction opposite the first direction to release the declutching mechanism and allow the clutch to reengage. |
