The utility model content
Technical problem to be solved in the utility model is: provide the little moment of torsion of a kind of electric current big elec. vehicle automatic gear shifting speed changing mechanism.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: elec. vehicle automatic gear shifting speed changing mechanism, comprise: shell, be respectively arranged with main drive shaft, first driven shaft, second driven shaft and the 3rd driven shaft in described shell, described main drive shaft is provided with main driven wheel; Described first driven shaft is provided with first driven gear, is respectively arranged with the second driven big gear wheel and the second driven miniature gears on described second driven shaft; On described the 3rd driven shaft, be respectively arranged with the 3rd driven big gear wheel and the 3rd driven miniature gears, in the described the 3rd driven big gear wheel, be provided with driven big gear wheel free-wheel clutch, in the described the 3rd driven miniature gears, be provided with driven miniature gears free-wheel clutch; Described first driven gear is meshing with each other with main driven wheel, the second driven big gear wheel and the 3rd driven miniature gears respectively, and the second driven big gear wheel and the 3rd driven miniature gears are meshing with each other, and the second driven miniature gears and the 3rd driven big gear wheel are meshing with each other.
The utility model has the advantages that: above-mentioned elec. vehicle automatic gear shifting speed changing mechanism, 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 the utility model elec. vehicle automatic gear shifting speed changing mechanism.
When removing for Fig. 1 that main drive shaft is just changeing behind the shell, Fig. 2 looks up structural representation.
When removing main drive shaft counter-rotating behind the shell for Fig. 1, Fig. 3 looks up structural representation.
Among the figure: 1, shell, 2, main drive shaft, 3, first driven shaft, 4, second driven shaft, 5, the 3rd driven shaft, 6, main driven wheel, 7, first driven gear, 8, the second driven big gear wheel, 9, the second driven miniature gears, the 10, the 3rd driven big gear wheel, the 11, the 3rd driven miniature gears, 12, driven big gear wheel free-wheel clutch, 13, driven miniature gears free-wheel clutch.
The specific embodiment
Describe particular content of the present utility model in detail below in conjunction with the drawings and specific embodiments.
As Fig. 1, Fig. 2, shown in Figure 3, elec. vehicle automatic gear shifting speed changing mechanism, comprise: shell 1, in described shell 1, be respectively arranged with main drive shaft 2, first driven shaft 3, second driven shaft 4 and the 3rd driven shaft 5, described main drive shaft 2 is provided with main driven wheel 6; Described first driven shaft 3 is provided with first driven gear 7, is respectively arranged with the second driven big gear wheel 8 and the second driven miniature gears 9 on described second driven shaft 4; On described the 3rd driven shaft 5, be respectively arranged with the 3rd driven big gear wheel 10 and the 3rd driven miniature gears 11, in the described the 3rd driven big gear wheel 10, be provided with driven big gear wheel free-wheel clutch 12, in the described the 3rd driven miniature gears 11, be provided with driven miniature gears free-wheel clutch 13; Described first driven gear 7 is meshing with each other with main driven wheel 6, second driven big gear wheel 8 and the 3rd driven miniature gears 11 respectively, the second driven big gear wheel 8 and the 3rd driven miniature gears 11 are meshing with each other, and the second driven miniature gears 9 and the 3rd driven big gear wheel 10 are meshing with each other.
During use, main drive shaft 2 can be connected with the rotating shaft of motor, and by 2 rotations of motor-driven main drive shaft, main drive shaft 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 seat 15.
As shown in Figure 1 and Figure 2, when motor is just changeing, motor drives main driven wheel 6 by main drive shaft 2 just to be changeed, main driven wheel 6 drives first driven gear intermeshing with it, 7 rotations, first driven gear 7 drives intermeshing with it the second driven big gear wheel 8 and the 3rd driven miniature gears 11 rotations, thereby drive second driven miniature gears 9 rotations, the second driven miniature gears 9 drives the intermeshing with it the 3rd driven big gear wheel 10 rotations.When motor is just changeing, the hand of rotation of the 3rd driven big gear wheel 10 is consistent with the hand of rotation of the 3rd driven shaft 5, opposite with the hand of rotation of the hand of rotation of coaxial the 3rd driven miniature gears 11 of the 3rd driven big gear wheel 10 and the 3rd driven shaft 5, idle running on the 3rd driven shaft 5, at this moment, the moment of the 3rd driven shaft 5 outputs is bigger, and rotative speed is slower.
As Fig. 1, shown in Figure 3, during the motor counter-rotating, motor drives main driven wheel 6 counter-rotatings by main drive shaft 2, main driven wheel 6 drives first driven gear intermeshing with it, 7 rotations, first driven gear 7 drives intermeshing with it the second driven big gear wheel 8 and the 3rd driven miniature gears 11 rotations, thereby drive second driven miniature gears 9 rotations, the second driven miniature gears 9 drives the intermeshing with it the 3rd driven big gear wheel 10 rotations.During the motor counter-rotating, the hand of rotation of the 3rd driven miniature gears 11 is consistent with the hand of rotation of the 3rd driven shaft 5, opposite with the hand of rotation of the hand of rotation of coaxial the 3rd driven big gear wheel 10 of the 3rd driven miniature gears 11 and the 3rd driven shaft 5, idle running on the 3rd driven shaft 5, at this moment, the moment of the 3rd driven shaft 5 outputs is less, and rotative speed is very fast.
The foregoing description is only for the usefulness that the utility model is described; and be not to be to restriction of the present utility model; person skilled in the relevant technique; under the situation that does not break away from the utility model spirit and protection domain; can also make various variations and modification, so all technical schemes that are equal to also should belong to protection category of the present utility model.
