Abstract
The invention discloses an electric shifting executing device of a double clutch automatic transmission, wherein the electric shifting executing device consists of two identical executing mechanism and detection devices. A motor is provided on a casing of the transmission and drives a reduction gear to be transmitted to a shifting hub. A guide groove of the shifting hub is connected with a shifting finger. The shifting hub drives shift forks of two groups of shift fork shafts to perform axial motion so as to accomplish the motion of engaging a gear and reversing the gear sequentially and intermittently. The two identical shifting hubs respectively and individually drive odd gears and even gears of the transmission, cancelling the time for selecting a gear and achieving automatic gear shifting and convenient and reliable control. Displacement signals of the shift fork shaft are detected by an angle sensor to control the operation of the motor, satisfying the demand on uninterrupted power for the double clutch automatic transmission and also the requirement of gear jumping. The device has a simple structure, and the arrangement of the device is not limited by the space. The device can also be used for shifting control of various electric control mechanical-type automatic transmissions.
Description
Technical field the present invention relates to a kind of automatic transmission electric shifting executing device of automobile, refers more particularly to a kind of double-clutch automatic speed changer for automobile electric shifting executing device.
The automatically controlled shifting implementation device of the current automatic gearbox of background technique mainly adopts hydraulic pressure and motor to drive two kinds of driving mode.Wherein to have a capacity large, easy and simple to handle for hydraulic pressure, is easy to realize safety protection, has certain absorbing and the ability of impact-absorbing.But for the hydraulic pressure components and parts, require machining accuracy high, complex structure, cost is high, and the impact that service behaviour is subject to ambient temperature is large, the shortcomings such as hydraulic fluid leak befouling environment.And motor drives and to be generally direct current generator and to utilize the power source driving on car, have simple in structure, controllability is good, precision is high, reaction is fast, reliability is strong, adaptability to ambient temperature is good, but, the automatically controlled shifting implementation device of automatic gearbox adopts gear selecting and gear shift two cover mechanisms to realize gear-change operation usually at present, change to another shelves from shelves and all needed to move back shelves, gear selecting, three processes of engage a gear, shift time is long, do not realize that power does not interrupt the requirement of gear shift, do not reach upgrading of double-clutch automatic gearbox yet, lower category and across the requirement of shelves.The actuating device that saves the gear selecting process is also arranged, but its each motor can only be managed a shift fork, 3 shift forks of the speed changer of 5 general gears that must indispensable 3 motors, then in the deceleration system added separately, cause bulkyly, be difficult to realize the coupling of car load.
Summary of the invention the objective of the invention is a kind of electric shifting executing device of double clutch automatic transmission that the deficiency of the automatically controlled shifting implementation device of current automatic gearbox is proposed, can meet that double-clutch automatic speed changer for automobile power is unbroken realizes gear shift, can meet double-clutch automatic speed changer for automobile upgrades, lower category, across the demand of shelves.
The technological scheme of the actuating device of double-clutch automatic speed changer for automobile electric gear-shifting actuating mechanism of the present invention is that actuator and the detection device that described electric shifting executing device is identical by two covers forms, the described actuator of case of transmission inner support and detection device.Every suit actuator detection device comprises: motor, primary speed-down gear, double-reduction gear, declutch shift shaft, hub range shift, magnet and angle transducer.Motor is fixed on case of transmission by centering, and the motor output shaft wheel connects (one group of reduction gear) primary speed-down gear, and the primary speed-down gear connects double-reduction gear, and double-reduction gear is connected with the gear of hub range shift.Circular hub range shift is provided with guide groove, and the expansion shape track of guide groove meets the order requirement of stroke and the gear of gear.Guide groove connects the reversal means of two secondary declutch shift shafts, drives shift fork and does axial motion.Hub range shift often rotated a circle 4 gear engage a gears, move back shelves actions.Turn 90 ° of engage a gears that complete a gear, move back shelves, 90 °, two gear intervals, realize self-locking, the interlocking of gear.Hub range shift one end is provided with magnet, on case of transmission and the hub range shift mounting hole angle transducer is installed outward, detect the declutch shift shaft displacement signal, control the forward and reverse rotation running of motor.
The actuator that two covers of the present invention are identical and the hub range shift of detection device design independent drive speed transmission odd number shelves and even number shelves, cancelled the time of gear selecting, realize automaitc shfit, and detect the signal of gear by angle transducer, complete orderly engage a gear, move back shelves action.Meet and meet the unbroken demand of dual-clutch transmission power, also meet the demand across shelves simultaneously.And to self-locking, the interlocking performance that has also possessed Transmission gear on mechanical structure.This apparatus structure is simple, arranges the restriction be not subject to space, controls convenient and reliablely, and the gear shift that also can be used for various electric control mechanical type automatic speed variators is controlled.
