Embodiment
Below in conjunction with accompanying drawing, the utility model is described further: as shown in Figure 1, a kind of shifter automatically, it is characterized in that: output shaft 13 is arranged in shifter shell 6, output shaft 13 front end is stretched out from the end cap 7 of shifter shell 6 front end, output shaft bearing 9 and spacer 10 is had between end cap 7 and output shaft 13, output shaft 13 front end is fixedly connected with output flange 8 with pad 11 by set nut 12, output shaft 13 rear end is stretched out from shifter shell 6 rear end end cap and is fixedly connected with input flange 4, by this structure, input flange 4 and output flange 8 can relatively rotate, input flange 4 passes through spline joint through support 2 and the drive unit 1 of back-end support, bearing is had between support 2 and input flange 4, bearing (ball) cover on support 23 pairs of bearings are spacing, be connected with motor 14 below drive unit 1, output shaft 13 is evenly equipped with the boss 15 of 4 circular shapes, specifically be positioned at output shaft 13 part of shifter shell 6 shell, sheet spring 5 adopts L-type structure, one end of sheet spring 5 is fixedly connected with the inwall middle section position of shifter shell 6, and other end end contacts with the boss 15 on output shaft 13.
Described drive unit 1 is the gear actuator on micro-machine AMT speed-changer, and by turbine and worm, mechanism forms, and ratio of gear is 57, and transmission efficiency is 0.68.
Support 2 endoporus coordinates with bearing outer ring, and for supporting, installing automatic shifter assembly, bearing (ball) cover 3 is for limiting bearing axial location; Input flange 4 is connected with drive unit 1 by spline, and is connected with shell 6 by bolt, and middle part coordinates with bearing inner race; Shell 6 is passed to for the rotating speed that exported by drive unit 1 and moment of torsion; Sheet spring 5 adopts L-type structure, and one end is embedded on shell 6, rotates together with shell 6, and the other end is stirred on output shaft 13, transmitting torque and rotating speed; The inner L-type groove of shell 6 is used for stator spring 5, and two ends and end cap 7 are bolted; End cap 7 is connected with shell 6 by bolt, and for limiting the axial location of sheet spring 5, endoporus coordinates with bearing outer ring, spring bearing; Output flange 8 is connected with output shaft 13 by spline, exports to mechanism loading for the moment of torsion that produced by automatic shifter and rotating speed; Output shaft bearing 9 is played a supporting role in each revolving part; Spacer 10 is for limiting the axial location of bearing and flange; Pad 11 transmits the axle pressure of set nut 12, and makes output flange 8 uniform force; Set nut 12 is for limiting the axial location of output flange 8; Output shaft 13 end coordinates with bearing inner race, and keeps coaxial with shell 6; Surface is uniform 4 boss along the circumferential direction, and improve hardness through carburizing and quenching, projection section contacts with the end of sheet spring 5, for the rotating speed of sheet spring 5 and moment of torsion are passed to output flange; Motor 14 is connected with drive unit 1 by bolt, and output terminal is connected with the worm screw on drive unit 1, for output torque and rotating speed.
The rotating speed that motor 14 exports by drive unit 1 and moment of torsion pass to shell 6, the sheet spring 5 be fixed on shell 6 is followed shell 6 and is rotated together, the end of sheet spring 5 is stirred on output shaft 13, thus the rotating speed of shell 6 and moment of torsion are passed to output shaft 13 and output flange 8; Sheet spring 5 can produce certain flexural deformation along with the increase of load, when the load of output flange 8 large to a certain extent time, the sheet spring 5 end boss that can skim on output shaft 13 continues to rotate, thus makes shell 6 realize idle running.
The nominal torque of automatic shifter and the quantity of sheet spring 5 proportional, being directly proportional to the width of sheet spring 5, by changing quantity and the width of sheet spring 5, the nominal torque of automatic shifter can being changed.Automatic shifter nominal torque parameter is in table 1.Sheet spring width is 225mm to the maximum, and maximum nominal torque is 30Nm.
Automatic shifter selects the special step electric machine of micro-car AMT, the family curve of motor under dutycycle is 100% condition as shown in Figure 5, now the rotating speed of shifter is rated speed, as calculated, the relation of rated speed and nominal torque meets formula n=102-2.92T, wherein n is rated speed, and T is nominal torque.
As shown in Figure 6, in figure, TCU16 is micro-car AMT real vehicle TCU to automatic shifter adjustment method, by notebook 18 and CANape software programming controlling test program, motor 14 can be rotated continuously, and speed setting dutycycle according to actual needs.Can remove notebook 18 and CANcardXL17 after having debugged, after switching on power, TCU16 can operate by automatic control motor, and automatic shifter can normally work, and meets testing requirements completely.
