DRIVE TRAIN FOR A PTO SHAFT |
| 摘要 |
A method and apparatus are disclosed for preventing rotation of a PTO shaft of a an agricultural vehicle when a clutch connecting the PTO shaft to a crankshaft of an engine of the vehicle is disengaged. A magnetic brake 22 is used to apply to the PTO shaft means a retarding torque by means of a fixed magnet a retarding torque of a magnitude exceeding the maximum output torque of the clutch when the latter is disengaged. |

1. A method of preventing rotation of a power take-off (PTO) shaft of an agricultural vehicle when a clutch connecting the PTO shaft to a crankshaft of an engine of the agricultural vehicle is disengaged, comprising:
applying to the PTO shaft a retarding torque of a magnitude exceeding a maximum output torque of the clutch when the clutch is disengaged, wherein the retarding torque is applied by one or more stationary magnets and an armature rotatable with the PTO shaft having circumferentially spaced pole pieces of ferromagnetic material. |
