Summary of the invention
Technical problem to be solved by this invention is: provide the little moment of torsion of a kind of electric current big electric vehicle automatic gear shifting speed changing mechanism.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: electric vehicle automatic gear shifting speed changing mechanism, comprise: shell, be respectively arranged with main driving axle, first driven shaft, second driven shaft and the 3rd driven shaft in described shell, described main driving axle is provided with main actuation gear; Described first driven shaft is provided with first driven gear, is respectively arranged with the second driven gearwheel and the second driven small gear at described second driven shaft; Be respectively arranged with the 3rd driven gearwheel and the 3rd driven small gear at described the 3rd driven shaft, in the described the 3rd driven gearwheel, be provided with driven gearwheel overrunning clutch, in the described the 3rd driven small gear, be provided with driven small gear overrunning clutch; Described first driven gear is meshing with each other with main actuation gear, the second driven gearwheel and the 3rd driven small gear respectively, and the second driven gearwheel and the 3rd driven small gear are not meshing with each other, and the second driven small gear and the 3rd driven gearwheel are meshing with each other.
Advantage of the present invention is: above-mentioned electric vehicle automatic gear shifting speed changing mechanism, and the little moment of torsion of electric current is big, and its moment of torsion can improve tens of times, and extending battery life about 50% can satisfy requirements such as climbing, speed-raising and load-carrying.
Description of drawings
Fig. 1 is the structural representation of electric vehicle automatic gear shifting speed changing of the present invention mechanism.
When removing for Fig. 1 that main driving axle is just changeing behind the shell, Fig. 2 looks up structural representation.
When removing main driving axle counter-rotating behind the shell for Fig. 1, Fig. 3 looks up structural representation.
Among the figure: 1, shell, 2, main driving axle, 3, first driven shaft, 4, second driven shaft, 5, the 3rd driven shaft, 6, main actuation gear, 7, first driven gear, 8, the second driven gearwheel, 9, the second driven small gear, the 10, the 3rd driven gearwheel, the 11, the 3rd driven small gear, 12, driven gearwheel overrunning clutch, 13, driven small gear overrunning clutch.
Embodiment
Describe particular content of the present invention in detail below in conjunction with the drawings and specific embodiments.
As Fig. 1, Fig. 2, shown in Figure 3, electric vehicle automatic gear shifting speed changing mechanism, comprise: shell 1, in described shell 1, be respectively arranged with main driving axle 2, first driven shaft 3, second driven shaft 4 and the 3rd driven shaft 5, described main driving axle 2 is provided with main actuation gear 6; Described first driven shaft 3 is provided with first driven gear 7, is respectively arranged with the second driven gearwheel 8 and the second driven small gear 9 at described second driven shaft 4; Be respectively arranged with the 3rd driven gearwheel 10 and the 3rd driven small gear 11 at described the 3rd driven shaft 5, in the described the 3rd driven gearwheel 10, be provided with driven gearwheel overrunning clutch 12, in the described the 3rd driven small gear 11, be provided with driven small gear overrunning clutch 13; Described first driven gear 7 is meshing with each other with main actuation gear 6, the second driven gearwheel 8 and the 3rd driven small gear 11 respectively, the second driven gearwheel 8 and the 3rd driven small gear 11 are not meshing with each other, and the second driven small gear 9 and the 3rd driven gearwheel 10 are meshing with each other.
During use, main driving axle 2 can be connected with the rotating shaft of motor, and by 2 rotations of motor driving main driving axle, main driving axle 2, first driven shaft 3, second driven shaft 4 and the 3rd driven shaft 5 are all walked around in shell 1 by bearing 14 and bearing support 15.
As shown in Figure 1 and Figure 2, when motor is just changeing, motor drives main actuation gear 6 by main driving axle 2 just to be changeed, main actuation gear 6 drives first driven gear intermeshing with it, 7 rotations, first driven gear 7 drives intermeshing with it the second driven gearwheel 8 and the 3rd driven small gear 11 rotations, thereby drive second driven small gear 9 rotations, the second driven small gear 9 drives the intermeshing with it the 3rd driven gearwheel 10 rotations.When motor is just changeing, the sense of rotation of the 3rd driven gearwheel 10 is consistent with the sense of rotation of the 3rd driven shaft 5, opposite with the sense of rotation of the sense of rotation of coaxial the 3rd driven small gear 11 of the 3rd driven gearwheel 10 and the 3rd driven shaft 5, in 5 idle running of the 3rd driven shaft, at this moment, the moment of the 3rd driven shaft 5 outputs is bigger, and rotational speed is slower.
As Fig. 1, shown in Figure 3, during the motor counter-rotating, motor drives main actuation gear 6 counter-rotatings by main driving axle 2, main actuation gear 6 drives first driven gear intermeshing with it, 7 rotations, first driven gear 7 drives intermeshing with it the second driven gearwheel 8 and the 3rd driven small gear 11 rotations, thereby drive second driven small gear 9 rotations, the second driven small gear 9 drives the intermeshing with it the 3rd driven gearwheel 10 rotations.During the motor counter-rotating, the sense of rotation of the 3rd driven small gear 11 is consistent with the sense of rotation of the 3rd driven shaft 5, opposite with the sense of rotation of the sense of rotation of coaxial the 3rd driven gearwheel 10 of the 3rd driven small gear 11 and the 3rd driven shaft 5, in 5 idle running of the 3rd driven shaft, at this moment, the moment of the 3rd driven shaft 5 outputs is less, and rotational speed is very fast.
Above-described embodiment is only for the usefulness that the present invention is described; and be not to be limitation of the present invention; person skilled in the relevant technique; under the situation that does not break away from the present invention's spirit and protection domain; can also make a variety of changes and modification, so all technological schemes that are equal to also should belong to protection category of the present invention.
