Enter the radial direction step cylindrical hole on axle 1, a part is the semi-spherical grooves being distributed on input gear inner edge, semi-spherical grooves diameter
Equal with big cylinder bore diameter, the plunger 4 is stepped cylinder, and the top of big cylinder is can be with half on input gear
The hemispherical that spherical groove is engaged, the bottom of small cylinder is round and smooth projection, the plunger 4 and the hemisphere on input gear inner edge
When shape groove is combined, input gear is connected as a single entity with input shaft 1, gear dallies around input shaft during disengagement.
The input shaft 1 is outer through being isometrical cylinder, reverse input gear, one grade of input gear 10, two grades of input teeth
Wheel 9, third gear input gear 8, fourth gear input gear 7, five grades of input gears 6, six grades of input gears 5 are sleeved on thereon successively, institute
Output shaft is stated parallel to input shaft 1, output shaft is rigidly connected with each output gear by spline.
The motor and gear 13 are arranged on the right-hand member bottom of 2 input shaft of gearbox 1, and the straight-tooth for covering 12 with sliding tooth is straight
Cooperation is connect, when motor and gear 13 rotate forward or backwards, then drives sliding tooth set 12 and gearshift land 17 to move to left or right
Move, the movement of gearshift land 17 will push the plunger 4 that it is contacted, this grade of plunger is tightly pressed to the half of this grade of input gear 11
In circular groove, input shaft 1 is set to be linked to be one with the selected middle gear in power shift gear.
The sliding tooth set 12 and gearshift land 17 use integrative-structure, and it, which is moved, is controlled by control ECU23 order-drivens
Motor action, it realizes that accurate control is to rely on the feedback of the information for being arranged on each gear position sensor that sliding tooth covers 12 right sides.
A kind of having the technical effect that based on the electronic automatic transmission that power is transmitted with axle and plunger of the present invention:
Compared with existing AT, AMT, CVT, DSG automatic transmission, he employ before several automatic transmission so
Toward different gearshift modes.Here by the rotation of motor and gear 13, sliding tooth set 12 is driven and land 17 of shifting gears
The mobile and selected gear plunger 4 shifted gears is locked, and is allowed to the structure that is connected as a single entity.So as to by the rotation of input shaft 1, pass through
Gear pair directly drives the rotation of output shaft to output power.
Its gearshift is implemented in the case where not cutting off power, power when can not so change vehicle traveling, runs vehicle
It is comfortable steady, oil consumption is reduced, strengthens the power of vehicle;Also reduce environmental noise simultaneously;Application on gear-box, can increase
Gear pair, improves and improves the performance of speed changer;Production technology simplifies, and cost is low, it is easy to manufacture.
