(among the figure: four short parallel liness, representative is captiveed joint with former car gearshift frame.)
In Fig. 2, Fig. 3, part 1,5,7,8,11,12,13,14 is former car gearshift parts, and all the other are for adding piece installing.
The specific embodiment
In implementing illustration, handle (1), ball journal (5), block selecting bar (14), gear level (7) connect firmly as shown, with the ball journal axis swing.
Shown in the figure: block selecting bar (14) axis, gearshift crank (6) are stirred the end axis of sensor crank (4) notch, are separately positioned on the extended line of the y axle of ball journal original coordinates among the figure and x axle.
It is the block selecting process that handle swings along the y direction of principal axis, after the block selecting, is shift process along the swing of x direction of principal axis.
In first embodiment Fig. 2:
During block selecting, block selecting bar (14) is stirred block selecting crank (12) notch up and down along the z direction of principal axis, and block selecting crank (12) is swung in the parallel plane on xz plane around block selecting crank shaft (13), and its displacement is corresponding with the block selecting line.Block selecting crank (12) is in pulling block selecting backguy (11), drive is installed in permanent magnet (10) swing of block selecting crank (12) lower end, parallel with its swinging plane and be fixed in the wiring board (15) on the frame, design the installation site of three reed capsules (9), corresponding with three block selecting points on the block selecting line respectively.Therefore when block selecting puts in place, there is corresponding information to be transferred to ECU, when as coordinate, angular-motion transducer numerical value change direction when in addition shifting gears, ECU just can judge the gearshift target.
During gearshift, gear level (7) is along x direction of principal axis swing, is packed in gearshift crank (6) on the gear-shift lever (7) under the drive of gear level (7), swings up and down in the plane that is made of handle (1) and gear level (7), and its displacement is corresponding with the line of shifting gears.Gearshift crank (6) is stirred the end axle of sensor crank (4) notch, stir sensor crank (4), rotate in the sensor axle sleeve (2) of sensor crank shaft on fixed frame, angular-motion transducer a (3) numerical values recited that is fixed on the frame is changed, show at the block selecting coordinate and determine gearshift intention, moving process and completion status under the prerequisite.When gearshift was finished, block selecting point parameter added the numerical value of shifting points place sensor, is current shift.
Because gearshift crank (6) is stirred the end axle of sensor crank (4) notch, design is on ball journal (5) x axle extended line, so when handle (1) is done block selecting when swing of vertical x axle in the yz plane, the rotation of end axle can not stirred sensor crank (4) notch and changed the numerical value of sensor (3).
In like manner, the gearshift action can not influence the position at that time of the permanent magnet (10) of block selecting crank (11) lower end yet.
Therefore, when needing gearshift, handle is put from current shift and is taken, and pushes the block selecting line to, and angular-motion transducer numerical value changes, and showing the gearshift intention, and ECU instructs disengaging of clutch at once.Follow the tracks of the result of numerical value change, after gearshift puts in place, order power-transfer clutch in time to close according to rule, the gearshift overall process is finished.
