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 the electronic shifting implementation device of a kind of automatic transmission of automobile, refers more particularly to the electronic shifting implementation device of a kind of double-clutch automatic speed changer for automobile.
The automatically controlled shifting implementation device of the present automatic gearbox of background technique mainly adopts hydraulic pressure and two kinds of driving mode of motor driving.Wherein to have a capacity big, easy and simple to handle for hydraulic pressure, is easy to realize safety protection, has certain absorbing and absorb the ability of impacting.But require the machining accuracy height for the hydraulic pressure components and parts, complex structure, the cost height, the influence that service behaviour is subjected to ambient temperature is big, shortcomings such as hydraulic fluid leak befouling environment.And being generally direct current generator, motor driving utilizes power source driving on the car, have simple in structure, controllability is good, the precision height, reaction is fast, good reliability, 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, changing to another shelves from shelves all needs to finish and moves 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, does not reach upgrading of double-clutch automatic gearbox yet, the requirement that lowers category and stride 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, again in the deceleration system that adds separately, cause bulkyly, be difficult to realize the coupling of car load.
Summary of the invention the objective of the invention is the electronic shifting implementation device of a kind of double-clutch automatic gearbox that the deficiency of the automatically controlled shifting implementation device of present automatic gearbox is proposed, can satisfy the unbroken realization gear shift of double-clutch automatic speed changer for automobile power, can satisfy double-clutch automatic speed changer for automobile upgrades, lower category, stride the demand of shelves.
The technological scheme of the actuating device of the electronic gear-shifting actuating mechanism of double-clutch automatic speed changer for automobile of the present invention is made up of identical actuator and the detection device of two covers, supports whole device in the case of transmission.Actuator's detection device comprises: motor, reduction gear, magnet, angle transducer, declutch shift shaft and hub range shift.Motor is fixed on the case of transmission by centering, and the gear of the output shaft of motor connects (one group of reduction gear) one-level reduction gear, and the one-level reducer gear connects double-reduction gear, and double-reduction gear is connected with the gear of hub range shift one end.Circular hub range shift is provided with guide groove, and the expansion shape track of guide groove meets the order requirement of the stroke and the gear of gear.The guide groove of hub range shift connects dialling of two secondary declutch shift shafts and refers to, drives shift fork and does axial motion.Hub range shift whenever rotates a circle and finishes 4 gear engage a gears, moves back the shelves action.Change 90 ° of engage a gears of finishing a gear, move back shelves, 90 ° at interval of two gears are realized self-locking, the interlocking of gear.Hub range shift one end is provided with magnet, with the hub range shift mounting hole angle transducer is installed outward on the case of transmission, detects the declutch shift shaft displacement signal, the forward and reverse rotation running of control motor.
The actuator that two covers of the present invention are identical and the hub range shift design single driving speed changer odd number shelves and the even number shelves of detection device, cancelled the time of gear selecting, realize automaitc shfit, and detect the signal of gear, finish engage a gear orderly, move back the action of shelves by angle transducer.Satisfy and meet the unbroken demand of dual-clutch transmission power, also satisfied simultaneously demand of striding shelves.And to self-locking, the interlocking performance that has also possessed Transmission gear on the mechanical structure.This apparatus structure is simple, arranges not to be subjected to the restriction in space, control convenient and reliablely, and the gear shift that also can be used for various electric control mechanical type automatic speed variators is controlled.
