Description
Technical field
The present invention relates to heavy-duty automotive speed changer gearshift, be specially a kind of heavy-duty car AMT speed changer electrical servo gear shifting operator.
Background technique
Along with the development of domestic heavy-duty automotive speed changer, heavy-duty car AMT speed changer is in actual design, need a kind of gear shifting operator of a kind of high responsiveness, high reliability, long service life, produce the high usage requirement of the gear shift frequency to meet heavy-duty car AMT speed changer because of gear many (usually having 10 gears to the design of 16 gears).Heavy-duty car AMT speed changer now more adopts operation form of medium structure that is pneumatic, that surge, gear-change operation generally adopts cylinder or oil hydraulic cylinder as final controlling element, but cylinder or hydraulically operated characteristic seriously can will reduce the responsiveness of gear-change operation, and there is the shortcoming of wayward berth-changing strength in gearshift procedure.
Summary of the invention
The present invention adopts cylinder or oil hydraulic cylinder to there is the larger and problem of wayward berth-changing strength of responsiveness to solve existing gear shifting operator, provides a kind of heavy-duty car AMT speed changer electrical servo gear shifting operator.
The present invention adopts following technological scheme to realize: heavy-duty car AMT speed changer electrical servo gear shifting operator, comprise the manipulation screw mandrel and gear shift shell that are threaded with gear shifting rocking arm, actuating motor and planetary mechanism is provided with in gear shift shell, planetary mechanism comprises planetary ring gear and is fixed on the planet stent of planetary ring gear outer end, planetary ring gear center is provided with sun gear, the surrounding of sun gear is provided with the planet wheel engaged with sun gear and planetary ring gear, the output shaft of actuating motor is connected with the input shaft of planetary mechanism, the torque sensor connected with both is provided with between planet stent with manipulation screw mandrel.
The moment of torsion of real-tune TT & C final controlling element in gearshift procedure, to control berth-changing strength, meets the protection to the synchronizer shift shifter collar in speed changer main tank, greatly extends the working life of AMT speed changer.
Detailed process is as follows: actuating motor rotates, and drives manipulation screw mandrel to rotate by planetary mechanism after being slowed down, thus drives screw and gear shifting rocking arm to rotate, and completes gear shift action; When actuating motor reversion, drive screw and gear shifting rocking arm counterrotating, complete reverse gear shift action.
Reasonable in design of the present invention is reliable; adopt torque sensor Real-Time Monitoring gear shift moment; the usage requirement in reliability and life-span is met while improving responsiveness; to the protection of the synchronizer shift shifter collar in speed changer main tank; greatly extend the working life of AMT speed changer, there is the advantage that the action response deadline is short, repetitive positioning accuracy is high, parts size is little, lightweight and be easy to manufacture.
