Cold Planer Implement Drive Train Protection System

摘要

A method of protecting a drive train from sudden shocks in a machine having a rotatably-mounted implement selectively couplable to a driver by the drive train includes sensing the movement of teeth of an annular toothed surface of the input pulley to monitor the rotational speed of the input pulley, and disengaging the clutch if a programmable controller identifies at least one of a rapid deceleration of a speed of the input pulley, and a difference between the speed of the input pulley, and a calculated speed provided to the input pulley by the input belt from the driver.

1. In a machine having a rotatably-mounted implement and including a drive train coupled to a driver and the implement, the drive train including an implement drive gearbox coupled to the implement to provide rotary movement, the driver being selectively couplable by at least one clutch to provide rotary movement to the implement by at least one input belt providing rotary movement to an input pulley coupled to provide rotary movement to the implement drive gearbox, a method implemented by a programmable controller, of protecting the drive train from sudden shocks, the method comprising:
sensing the movement of teeth of an annular toothed surface of the input pulley to monitor a rotational speed of the input pulley, providing a signal indicative of the speed of the input pulley to the programmable controller, identifying at least one of
a rapid deceleration of the speed of the input pulley, anda difference between the speed of the input pulley, and a calculated speed provided to the input pulley by the input belt from the driver, disengaging the at least one clutch associated with the drive train when at least one of the following occurs
the rapid deceleration of the speed of the input pulley is identified, andthe difference between the speed of the input pulley and the calculated speed is in excess of a discrepancy threshold.
