Problems solved by technology
Among them, the design of the electric clutch mechanism is complex, the manufacturing cost is high, and the comfort is poor; the reliability of the pneumatic clutch mechanism is relatively poor, mainly because the quality of the air source on the car is difficult to guarantee and the consistency is difficult to control; and the dry electromagnetic clutch has insufficient torque load. And the control is not precise, it is easy to overheat and burn the friction plate, and it is difficult to adapt to the complex road conditions (such as dusty, wet road conditions, etc.)

The invention discloses an AMT system based on a wet type electromagnetic clutch structure. The AMT system comprises an engine, a hydraulic coupler, a wet type multi-piece electromagnetic clutch, a mechanical gearbox, a gear selecting and shifting executing mechanism and a controller TCU, wherein a flywheel is installed at the output end of the engine; a first driving disc is fixed to the input end of the hydraulic coupler; a first driven disc is installed at the output end of the hydraulic coupler; a second driving disc is fixed to the input end of the wet type multi-piece electromagnetic clutch; a second driven disc is installed at the output end of the wet type multi-piece electromagnetic clutch; and the input ends of the engine, the hydraulic coupler, the wet type multi-piece electromagnetic clutch and the gear selecting and shifting executing mechanism are all electrically connected with the output end of the controller TCU. According to the AMT system based on the wet type electromagnetic clutch structure, the comfort during driving is improved, the AMT system has the advantages of being compact in structure, high in reliability and high in transmission efficiency, the problem that a dry-type electromagnetic clutch is low in road condition adaptability is solved, and the control precision is effectively improved.
Description
technical field [0001] The invention relates to the technical field of an AMT gearbox system for a commercial fuel vehicle, in particular to an AMT system based on a wet electromagnetic clutch structure. Background technique [0002] At present, there are three types of clutch actuators used in the market: electric, pneumatic and dry electromagnetic clutches. Among them, the design of the electric clutch mechanism is complex, the manufacturing cost is high, and the comfort is poor; the reliability of the pneumatic clutch mechanism is relatively poor, mainly because the quality of the air source on the car is difficult to guarantee and the consistency is difficult to control; and the torque load of the dry electromagnetic clutch is insufficient. And if the control is not precise, it is easy to overheat and burn the friction lining, and it is difficult to adapt to the needs of complex road conditions (such as dusty, wet road conditions, etc.). [0003] Therefore, those skille...
