Description
Technical field
The present invention relates to a kind of electric vehicle gear boxes to be driven buffer structure.
Background technique
Such as application No. is the Chinese invention patents of CN201410604182.3 to disclose a kind of purely mechanic fourth gear change of electric vehicle
Fast case, the gearbox realize electric vehicle fourth gear by purely mechanic mechanism and drive speed change.But in practical application, the speed change
Case can be different with output gear revolving speed due to input shaft in shift, cause the transmission gear of rear class by excessive impact, thus
The transmission gear of rear class is caused often to be played damage.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of electric vehicle gear boxes to be driven buffer structure, the electric vehicle
Gearbox transmission buffer structure can effectively buffer gearbox revolving speed and motor speed difference by elastic construction and position limiting structure
Caused shift shock, to effectively extend the Acceptable life of gearbox.
The present invention is achieved by the following technical programs.
A kind of electric vehicle gear box provided by the invention is driven buffer structure, including input shaft and output shaft；The input
Shaft end portion is provided with input tooth；The input shaft integral middle is provided with circular mounting seat, is arranged on an end face of mounting base
There is the mounting disc of indent, is provided with limited block at the top of mounting disc side wall；The output sleeve leans on mounting disc institute on input shaft
One side, output gear, output gear engaged transmission gearbox are provided on output shaft；The output shaft is in by mounting disc one end
End sides have been wholely set fixture block, so that input shaft can drive output shaft rotation by limited block, fixture block.
It further include buffer spring, buffer spring is sleeved on input shaft, between output shaft and mounting base；Buffer spring
One end inserting is fixed on output shaft end, and other end inserting is fixed in mounting disc.
The fixture block quantity is two, and two fixture blocks are relative to output shaft setting substantially symmetrical about its central axis.
The limit number of blocks is two, and two limited blocks are relative to input shaft setting substantially symmetrical about its central axis.
On the input shaft relative to input tooth other end end at one end be additionally provided with tooth connection.
The present invention is applied to be driven between electric vehicle engine and gearbox
The beneficial effects of the present invention are: by elastic construction and position limiting structure, it can effectively buffer gearbox revolving speed and electricity
Shift shock caused by motivation speed difference, to effectively extend the Acceptable life of gearbox；Structure setting is reasonable, cost
It is cheap, it occupies small in size.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
In figure: 11- input shaft, 12- input tooth, 13- mounting base, 14- limited block, 15- mounting disc, 16- tooth connection, 21-
Output shaft, 22- output gear, 23- fixture block, 24- buffer spring.
Specific embodiment
Be described further below technical solution of the present invention, but claimed range be not limited to it is described.
A kind of electric vehicle gear box as shown in Figure 1 is driven buffer structure, including input shaft 11 and output shaft 21；It is described defeated
Enter 11 end of axis and is provided with input tooth 12；11 integral middle of input shaft is provided with circular mounting seat 13, and the one of mounting base 13
It is provided with the mounting disc 15 of indent on a end face, is provided with limited block 14 at the top of 15 side wall of mounting disc；The output shaft 21 is set with
Output gear 22 is provided on one side where mounting disc 15, output shaft 21 on input shaft 11,22 engaged transmission of output gear becomes
Fast case；The output shaft 21 is in being wholely set fixture block 23 by the end sides of 15 one end of mounting disc, so that input shaft 11 can be by
Limited block 14, fixture block 23 drive output shaft 21 to rotate.
As a result, since output shaft 21 can be rotated relative to input shaft 11, motor will not directly drive gearbox,
To avoid shift shock, and pass through the setting of limited block 14 and fixture block 23, motor can also drive speed change through the invention
Case, therefore the speed difference of motor and gearbox can be reduced by any buffer structure.
It further include buffer spring 24 as the most preferably scheme of buffer structure, buffer spring 24 is sleeved on input shaft 11,
Between output shaft 21 and mounting base 13；The inserting of 24 one end of buffer spring is fixed on 21 end of output shaft, and other end inserting is solid
It is scheduled in mounting disc 15.
It finds by many experiments, if output shaft 21 rotates more than 220 ° relative to input shaft 11, is used for a long time very
It is easy that buffer structure is made to fail, therefore 23 quantity of the fixture block is two, and two fixture blocks 23 are relative to 21 central axis of output shaft
It is symmetrical arranged.
Further, alternative and reinforcing the scheme as limitation output shaft 21 relative to the rotation of input shaft 11, it is described
14 quantity of limited block is two, and two limited blocks 14 are relative to the setting substantially symmetrical about its central axis of input shaft 11.
Further, 11 end of input shaft generally also needs to connect other structures, therefore opposite on the input shaft 11
In input tooth 12 other end end at one end be additionally provided with tooth connection 16.
In general, clutch can preferably realize function of the invention, it is apparent that in electric vehicle, especially two-wheeled or
Clutch is used in the electric vehicle of three-wheel, will cause a series of problems, such as vehicle transmission structure volume is excessive, and technology of the invention
Scheme is how many greatly unlike general transmission shaft, capacity issue is not present, therefore present invention is particularly suitable for electric vehicle engines
It is driven between gearbox.
