Description

It is a kind of based on the electronic automatic transmission that power is transmitted with axle and plunger
Technical field
It is more particularly to a kind of to be based on transmitting with axle and plunger the present invention relates to Car Electronic Control automatic transmission field The electronic automatic transmission of power.
Background technology
Vehicle automatic speed variator using so far, by vast home and abroad customer acceptance and receiving, particularly car from Dynamic speed changer has developed to eight speed automatic transmission.Up to nowadays domestic load truck (large, medium and small type), domestic way-train (it is small, In, it is large-scale) automatic transmission is all seldom housed, reason is to produce automatic transmission complex process, and production cost is high, China's life The production automatic transmission time is short, lacks technology and experience.Producing automatic transmission can only be by introducing, while high-end product, high-end The controlled external producer of technology.Automatic transmission technology is developed, reaching world-class levels also, there is a big difference.The existing tooth of China Roller box production technology is perfect and maturation, and reaches certain level, and exploitation automatic transmission will walk the road tallied with the national condition , so just there is broad prospect on road.The present invention's is a kind of based on the electronic automatic transmission that power is transmitted with axle and plunger, and conventional Different gearshift modes, be different from other various automatic transmission, be suitable for the country conventional gearbox design feature, be New page is raised in domestic automatic transmission field development.
The content of the invention
The purpose of the present invention is to be based on above-mentioned actual conditions, with reference to the characteristics of domestic speed-changing gear box industry, rationally, effectively A kind of new-type shifting automated transmission is combined into, its implementation environment and condition is ripe, will be no longer by various restrictions, prospect It is broad.
Above-mentioned purpose of the present invention is described with reference to the drawings as follows:
It is a kind of based on the electronic automatic transmission that power is transmitted with axle and plunger, mainly by automatic speed-changing system 2 and electronics Control system 18 is constituted, the automatic gearshift that the automatic speed-changing system 2 is coordinated using plunger with axle, and the mechanism is by input shaft 1st, successively on the input shaft 1 reverse input gear and respectively gear input gear, output shaft, successively on output shaft with it is each The corresponding output gear of level input gear, reversing shaft and back gear 16, motor and gear 13 and plunger at different levels 4 are constituted, The input shaft 1 and output shaft are by bearings on the casing of speed changer, and the left end of input shaft 1 connection clutch is described defeated The main part for entering axle 1 is hollow cylindrical structure, is fixed with guide rod 3, guide rod 3 in it and is set with sliding tooth set 12 and gearshift Plunger hole radially and on the circumference of input gear inner edge is evenly equipped with land 17, the circumference of input shaft 1, the plunger hole and plunger 4 It is slidably matched, plunger 4 is in plunger hole, and the plunger 4 is controlled by electronic control system 18, by motor and gear 13 Plunger 4 is pressed into the plunger hole of corresponding input gear by driving sliding tooth set 12 and gearshift land 17, makes input shaft 1 and corresponding Input gear combine transmission power;The electronic control system 18 is held by sensor, control ECU23, motor and gearshift Row clutch 24 is constituted, and the sensor includes accelerator pedal sensor 19, vehicle speed sensor 20, gear position sensor 14, braking Pedal sensor 21 and clutch pedal sensor 22.
The plunger 4 and plunger hole are several, and the plunger hole is the two parts being correspondingly arranged, and a part is defeated to be distributed on 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.
