RAIL HANDBRAKE WITH PROLONGED RELEASE |
摘要 |
A prolonged release system having a locking member pivotally mounted on a post within a hand brake and having an arm that contacts a clutch assembly to prevent the clutch assembly of the handbrake from engaging after it has been manually released. Rotation of the hand brake wheel causes a pawl on a ratchet gear to move into contact with a cam of the locking member so that the arm of the locking member moves out of contact with the clutch assembly. By maintaining the clutch assembly in a released position, the prolonged release system ensures that the brake chain drum is decoupled from the driveshaft of the hand brake and prevents the inadvertent application of the brakes. When a user turns the hand brake wheel, the locking member is disengaged from the clutch assembly and the hand brake can be set by a user. |
