Specific embodiment
Presently in connection with attached drawing and preferred embodiment, the present invention is further illustrated.These attached drawings are simplified signal
Figure, the basic structure of the invention will be illustrated schematically only, therefore it only shows the composition relevant to the invention.
Embodiment: as shown in Figure 1, Figure 2 and Figure 3, a kind of gearbox of electric vehicle, including the input in cabinet 1, cabinet 1
Axis 2 stretches out the output shaft 3 outside cabinet 1 and the driven shaft 4 in cabinet 1, and input shaft 2 is equipped with input gear 13, driven
The both ends of axis 4 are respectively arranged with the first driving wheel 5 and the second driving wheel 6, the first driving wheel 5 and the opposite end of the second driving wheel 6
Toothing is provided on face, on the driven shaft 4 between the first driving wheel 5 and the second driving wheel 6 slideably be equipped with it is defeated
Enter the balladeur train 8 of the engagement of gear 13, is respectively equipped with and the first driving wheel 5, the second driving wheel 6 in the both ends of the surface of balladeur train 8
The toothing that matches of toothing, which is cooperated with driven shaft 4 by keyway 9, balladeur train 8 and input gear
13 drive output shaft 3 to rotate for intermeshing helical gear, the first driving wheel 5 and the second driving wheel 6 by gear drive.
Second driving wheel 6 drives output shaft 3 to rotate by gear drive, specific structure are as follows: transition axis is equipped in cabinet 1
10, the driven gear 11 engaged with the second driving wheel 6 is installed on the transition axis 10, driven gear 11 is also and on output shaft 3
Output gear 12 engages, and output gear 12 here is low-gear.
First driving wheel 5 drives output shaft 3 to rotate by gear drive, specific structure are as follows: the output gear on output shaft
12 engage with the first driving wheel 5, and output gear 12 here is quick gear.
Quick gear and low-gear can be separately mounted on two gears on output shaft 3, but preferably,
Output gear 12 include the gear ring at a slow speed 121 engaged with driven gear 11, the quick gear ring 122 engaged with the first driving wheel 5 with
And connection sleeve 123 between the two, connection sleeve 123, quick gear ring 122 are structure as a whole with gear ring 121 at a slow speed, connector sleeve
Isolator is equipped in cylinder 123.
Since balladeur train 8 slidably reciprocates between the first driving wheel 5 and the second driving wheel 6, in order to guarantee balladeur train 8
Always the height for engaging with input gear 13, therefore limiting input gear 13 is greater than the height of balladeur train 8.
It is engaged for the ease of balladeur train 8 with the first driving wheel 5 or the second driving wheel 6, the first driving wheel 5 and the second active
The toothing 7 of wheel 6 and the angle of its end face are 20 °~30 °；Balladeur train 8 and the first driving wheel 5 or the second active in order to prevent
The case where beating tooth after 6 engagement of wheel occurs, and the end of the toothing of the first driving wheel 5 and the second driving wheel 6 is plane.
In order to shorten shift time, preferably, the keyway on driven shaft 4 is helicla flute, and balladeur train 8 is more easily
It is rotated along helicla flute.
When object moves in a circle, it may appear that be directed toward the bonding force active force of the center of circle (center of curvature), i.e. normal force.Method
To power be directed toward circle center, and the object controlled by normal force be moved along the direction of tangent line, so normal force must with by
The direction of motion for controlling object is vertical, only generates the acceleration in speed normal direction.Therefore normal force only changes controlled object
The direction of motion, the rate without changing movement.As shown in Fig. 2, input gear 13 generates method when motor band driven input shaft 2 rotates
Xiang Li, since input gear 13 is helical gear, the gradient of tooth is bigger, and normal force is just bigger.
When specific operation, the general operating status of electric vehicle is in shelves at a slow speed: motor band driven input shaft 2 rotates forward, input gear
13 drive balladeur trains 8 along keyway 9 towards the second driving wheel 6 close to rear engagement, the second driving wheel 6 drive on transition axis 10 from
Moving gear 11 rotates, and since driven gear 11 is engaged with gear ring 121 at a slow speed, output gear 12 is driven to rotate, so that output
The rotation of axis 3 exports slow speed；
When electric vehicle needs climbing to use quick shelves: motor band driven input shaft 2 inverts, and input gear 13 drives balladeur train
8 engage towards the first driving wheel 5 close to rear along keyway 9, and the first driving wheel 5 is engaged with quick gear ring 122, drives output gear 12
Rotation, so that the rotation of output shaft 3 exports fast speed.
Being changed by the rotation direction of input shaft 2 to realize shift, and is shaft and gear in cabinet 1, structure is simple,
It is easy to make, quick.
In addition, the speed of output shaft 3 is greater than the speed of input shaft 2 when electric vehicle descending, isolator guarantees output shaft 3 not
Go that transition axis 10 and driven shaft 10 is driven to rotate, only 3 own rotation of output shaft, at this point, balladeur train 8 not with the first driving wheel 5
Engagement, is not also engaged with the second driving wheel 6.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand the contents of the present invention and be implemented, and it is not intended to limit the scope of the present invention, it is all according to the present invention
Equivalent change or modification made by Spirit Essence, should be covered by the scope of protection of the present invention.
