The control system calculates the temperature of the clutch system, based on one or more vehicle operational parameters. If the clutch system reaches a pre-determined temperature limit, the control system selectively stops the operation of the clutch system until the clutch temperature drops below the pre-determined temperature limit. The control system includes an electronic control unit, e.g., a computer or microprocessor, that calculates and/or processes one or more vehicle operational parameters, including, but not limited to: (1) clutch input and output speeds; (2) slip across the clutch; (3) clutch torque; (4) current clutch power; (5) accumulated clutch power; (6) temperature delta (i.e., change) of the clutch; and (7) clutch temperature.
Description
Technical field
The present invention relates generally to the power output clutch system, particularly clutch system reach a predetermined temperature boundary and overheated before optionally stop the power output clutch system of clutch system operation temporarily.
Background technique
Recently, four-wheel and all-wheel drive vehicles comprise those vehicles that has adopted the torque responsive system (for example, TOD of BorgWamer motor corporation
TMAnswer system) introducing, Safety performance and the cornering ability of vehicle under the suboptimum road conditions had very great help.In order to provide an independent drive power source accessory machinery (perhaps integrated and/or independently, as stirrer, compactor, capstan winch, packer and similar machinery), more such vehicles also adopt a kind of power output (PTO) system that unites with the master motor of vehicle.
Routine PTO system generally includes certain type clutch system.Conventional PTO clutch system generally includes an input link, an output link, and a cover clutch pack (a for example cover composite sheet or a dish) and one are used for optionally the control system with the engagement of input and output member.
Explanation to different four-wheel drives and torque responsive system can be at people's such as U. S. Patent McGinn Nos.5492194,5690002 of Showalter, 5839328 of Showalter, people such as 5884738 and the Showalter of Joslin 5966999 in find, their whole disclosures are included in this as a reference.
Because employed most of engine systems can produce the bigger moment of torsion of moment of torsion that can bear than the PTO system of routine in these type of vehicle, the potential destruction that the output of the moment of torsion of engine system causes so the operator of these vehicles will keep a close eye on for the PTO system.If clutch responds high moment of torsion input rank and slippage, most probable causes the generation of destruction, causes clutch pack overheated rapidly, thus potential destruction clutch plate.Must carry out the consuming time and expensive repairing and/or the replacement of part or all clutch pack this moment.
Therefore, suggestion must be monitored the clutch system temperature in order to protect clutch pack, clutch system is closed before the critical temperature or ends reaching.This can realize by the temperature of using a temperature transducer directly to measure this clutch system.
