Manually fixedly the shaft type gear-shift transmission is the step change driving mechanism, and its advantage is the efficient height, and cost is low, and mature production technology is widely used in China at present.Shortcoming is the gear shift difficulty, and power interruption during gear shift requires pilot control skilled, so people expect that it can realize automation.Computer Control Technology makes this gear realize that automaitc shfit becomes possibility.Electric control mechanical type automatic speed variator (AMT) is exactly the product that makes the fixed shaft transmission automation by microcomputer control.It kept original gear speed changer transmission efficiency height, installing space compactness, in light weight, cost is low, easy manufacturing, safeguard advantages such as easy; And realized the automation of starting, gearshift procedure, in handiness, possessed the advantage of AT.AMT with its economy, easy to usely, simple and safe have better travelling comfort again and favored; and it also has the advantage that the existing manual transmission of the desired high fuel economy of present automobile industry development, low emission and protection is produced investment, therefore has been subjected to the attention of each big automobile factory.
AMT is on the basis of conventional fixed axis transmission and dry clutch, application electric technology and automatic speed changing theory, with electronic control unit (TCU) is core, separation by the actuating mechanism controls clutch with engage, select gear-change operation and the fuel feeding by electronic equipment control motor, realize starting to walk, the automatic manipulation of gear shift.The basic thought of AMT control is: according to driver's the intention (accelerator pedal, brake petal, Joystick etc.) and the state (engine speed, input shaft rotating speed, the speed of a motor vehicle, gear) of vehicle, according to suitable control law (process of power shift, clutch rule etc.), the Power Train (motor, clutch, speed changer) of vehicle is carried out united control by means of corresponding actuator's (clutch actuating mechanism, gear-selecting and shifting executing mechanism) and electronic equipment (engine oil control electronic equipment).
ECU (Electrical Control Unit) (TCU) is shouldered collection, processing and the control decision of multichannel input signal and sending of execution command in real time, online according to software program; Then according to the instruction of TCU, control electromagnetic valve makes actuator automatically finish actions such as clutch separation, joint and speed changer select, change to operating control mechanism, and gearshift procedure is finished automatically.
Summary of the invention
The purpose of this utility model is to provide a kind of motor driving to select gear shifting operator, and it adopts storage battery power supply ready-made on the car, realizes choosing, gear shift action by positive and negative the transferring of electrical signal control final controlling element corresponding motor, comprises 3 gear selecting positions and 3 gear shift positions; Have berth-changing strength evenly, characteristics such as little, simple in structure, the cleaning of accurate positioning, shifting shock, easy care.
The technical solution of the utility model is achieved in that motor driving selects gear shifting operator, by selecting gear shifting operator main body, gear selecting motor, gear shifting motor, gear selecting sensor and gear shift sensor to form; It is characterized in that: the final controlling element main body by gear selecting reducing gear, shift down mechanism, gear selecting refer to, gear selecting is located, gear shift buffer, gear shift guide shaft, gear shift output, change gear and gear shift tooth fan are formed; The motor shaft end of gear selecting motor and gear shifting motor is processed into homalocephalus, and worm screw direct and in two-part reducing gear is connected, and strengthens with a metal ring respectively; The output torque of reducing gear is delivered to next stage through spline connection and gear-driven mode.
Described gear selecting refers to be installed togather with the gear shift guide shaft, gear shift tooth fan, gear shift shifting block and return spring are housed on the gear shift guide shaft, wherein the fan of the gear shift tooth on the gear shift guide shaft is installed togather with change gear, and change gear is connected by spline with the gear shift buffer.
Gear shift tooth fan on described change gear and the gear shift guide shaft is meshed, and it is that spline is connected jointly with pin that gear shift tooth fan is enclosed within on the gear shift guide shaft with the gear shift guide shaft.
Good effect of the present utility model is to make vehicle promptly have good power character, can guarantee good and economic, low processing cost, easy maintenance again simultaneously.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described; As Figure 1-3, motor driving is selected gear shifting operator, by selecting gear shifting operator main body 1, gear selecting motor 2, gear shifting motor 3, gear selecting sensor 4 and gear shift sensor 5 to form; It is characterized in that: final controlling element main body 1 by gear selecting reducing gear 10, shift down mechanism 14, gear selecting refer to 15, gear selecting location 13, gear shift buffer 9, gear shift guide shaft 8, gear shift output 6, change gear 11 and gear shift tooth fan 12 are formed; Gear selecting motor 2 is processed into homalocephalus with the motor shaft end of gear shifting motor 3, and worm screw direct and in two-part reducing gear is connected, and strengthens with a metal ring respectively; The output torque of reducing gear is delivered to next stage through spline connection and gear-driven mode.
Described gear selecting refers to that 15 are installed togather with gear shift guide shaft 8, gear shift tooth fan 12, gear shift shifting block 6 and return spring 7 are housed on the gear shift guide shaft 8, wherein the gear shift tooth on the gear shift guide shaft 8 fan 12 is installed togather with change gear 11, and change gear 11 and gear shift buffer 9 are connected by spline.
Gear shift tooth fan 12 on described change gear 11 and the gear shift guide shaft 8 is meshed, and gear shift tooth fan 12 is enclosed within on the gear shift guide shaft 8 with gear shift guide shaft 8 and is connected jointly with pin for spline.
Concrete working procedure is divided into gear selecting action and gear shift action two-part.The gear selecting action realizes it being to be slowed down to increase by worm and gear by the gear selecting motor to turn round, and the driving gear selecting refers to stir shift shaft and moves up and down, and realizes the gear selecting action; The gear shift action is to rotate through worm and gear deceleration rear driving gear shift buffer by gear shifting motor, and the buffering back is delivered to action on the change gear by spline, finishes the gear shift action thereby driving gear shift tooth fan drives the gear shift guide shaft.
The effect of gear shift buffer: the buffer portion of the similar of gear shift buffer 9 in dry clutch impulsion dish, can make gear shifting motor 3 proceed to speed changer when synchronous in gear shift action, be unlikely to form long stall, but slow down gradually, simultaneously with EOS the time, can the ring gear in the speed changer be meshed fast by the release of buffer spring.The inertia impact that produces when reducing the motor high speed rotating.
The reducing gear of gear selecting and gear shift part all adopts the worm and gear transmission, and requires not self-locking of transmission, and efficient is high as far as possible.Because gear selecting has special positioning wheel to guarantee, gear shift has speed changer itself to guarantee, only needs the efficient of raising system here.
This mechanism adopts closed loop control, selects gear shift sensor 5 to be directly installed on change gear 11 and the gear selecting worm gear, and signal directly reflected and select gear shift whether to put in place, for the just commentaries on classics of program decision motor, reverse and stop to provide accurate foundation.
