One side, output shaft is provided with output gear, output gear engaged transmission change speed gear box；Described output shaft is in by mounting disc one end
End sides has been wholely set fixture block so that power shaft can be driven output shaft rotation by limited block, fixture block.
Also including buffer spring, buffer spring is sleeved on power shaft, between output shaft and mounting seat；Buffer spring
One end plug-in mounting is fixed on output shaft end, and other end plug-in mounting is fixed in mounting disc.
Described card number of blocks is two, and two fixture blocks are relative to output shaft setting substantially symmetrical about its central axis.
Described limited block quantity is two, and two limited blocks are relative to power shaft setting substantially symmetrical about its central axis.
On described power shaft relative to input tooth other end end at one end be additionally provided with connection tooth.
The present invention is applied to transmission between electric vehicle engine and change speed gear box
The beneficial effects of the present invention is: by elastic construction and position limiting structure, can effectively buffer change speed gear box rotating speed and electricity
The shift shock that motivation speed difference causes, thus effectively extend the Acceptable life of change speed gear box；Structure arranges rationally, cost
Cheap, take volume little.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
In figure: 11-power shaft, 12-inputs tooth, 13-mounting seat, 14-limited block, 15-mounting disc, and 16-connects tooth, 21-
Output shaft, 22-output gear, 23-fixture block, 24-buffer spring.
Detailed description of the invention
Technical scheme is described further below, but claimed scope is not limited to described.
A kind of electric vehicle gear box transmission buffer structure as shown in Figure 1, including power shaft 11 and output shaft 21；Described defeated
Enter axle 11 end and be provided with input tooth 12；Described power shaft 11 integral middle is provided with circular mounting seat 13, the one of mounting seat 13
Being provided with the mounting disc 15 of indent on individual end face, mounting disc 15 Bian Bi top is provided with limited block 14；Described output shaft 21 is set with
By the one side at mounting disc 15 place on power shaft 11, output shaft 21 being provided with output gear 22, output gear 22 engaged transmission becomes
Speed case；Described output shaft 21 has been wholely set fixture block 23 in the end sides by mounting disc 15 one end so that power shaft 11 can be by
Limited block 14, fixture block 23 drive output shaft 21 to rotate.
Thus, owing to output shaft 21 can rotate relative to power shaft 11, therefore motor will not directly drive change speed gear box,
Thus avoid shift shock, and by limited block 14 and the setting of fixture block 23, motor can also drive speed change by the present invention
Case, therefore can reduce the speed difference of motor and change speed gear box by any buffer structure.
As the most preferably scheme of buffer structure, also include that buffer spring 24, buffer spring 24 are sleeved on power shaft 11,
Between output shaft 21 and mounting seat 13；Buffer spring 24 one end plug-in mounting is fixed on output shaft 21 end, and other end plug-in mounting is solid
It is scheduled in mounting disc 15.
Finding through great many of experiments, if output shaft 21 rotates more than 220 ° relative to power shaft 11, life-time service is very
Easily making buffer structure lose efficacy, the most described fixture block 23 quantity is two, and two fixture blocks 23 are relative to output shaft 21 central shaft
It is symmetrical arranged.
Further, as limiting output shaft 21 relative to the alternative of the rotation of power shaft 11 scheme strengthened, described
Limited block 14 quantity is two, and two limited blocks 14 are relative to power shaft 11 setting substantially symmetrical about its central axis.
Further, power shaft 11 end typically also needs to connect other structures, on the most described power shaft 11 relatively
It is additionally provided with in input tooth 12 institute other end end at one end and connects tooth 16.
It is said that in general, clutch can preferably realize the function of the present invention, it is apparent that in electric motor car, especially two-wheeled or
With clutch in the electric motor car of three-wheel, the excessive series of problems that waits of vehicle transmission structure volume can be caused, and the technology of the present invention
Scheme is how many greatly unlike general power transmission shaft, there is not capacity issue, therefore present invention is particularly suitable for electric vehicle engine
And transmission between change speed gear box.
