Description
Technical field
The present invention relates to automobile power transfer device, particularly a kind of differential type is isolated to close two shift transmissions.
Background technology
Because Electric Vehicles Driving Cycle difference causes speed difference bigger, if needing motor without speed changer
The wider range of speeds can be exported, very high to the performance requirement of motor, motor efficient operation section is limited, if motor
In low-power consumption regional work, energy consumption is larger, reduces electric automobile endurance.Although the performance of motor is better than engine, no
Need to configure the speed changer of more gears like that to engine, but be at least also required to that with one the two of high and low gear work can be realized
Speed automatic transmission.The dynamic interruption or two existing shift transmissions are shifted gears, otherwise need two control clutches to realize
Gearshift, a clutch unclamp, and the engagement of another clutch, due to not interrupted for power, a clutch is also without complete
During release, another clutch will engage, and so cause two clutches to have certain work schedule overlapping compared with angle, hold
It is also easy to produce the final service life for influenceing clutch of friction.The two-shift automatic speed variator of the present invention only has a clutch, controls
The clutch can realize that power does not interrupt gearshift.
Or analysis understands that current electric car automatic speed transmission shifting power interrupts more than, slipped when going up a slope
Slope phenomenon, otherwise easily abrasion is exactly that poor reliability or technology are not mature enough to clutch, therefore commercially two-gear automatic speed changing
It is device popularization and application and few.
The content of the invention
It is limited the invention aims to overcome and solve existing electric automobile motor efficient operation section, existing two
Or speed automatic transmission has shifting power interruption, occur slipping by slope phenomenon when going up a slope, otherwise the easy wear reliability of clutch
The shortcomings that poor and problem, there is provided a kind of differential type is isolated to close two shift transmissions, to realize that electronic function is operated in efficient operation
Region.
The technical solution adopted by the present invention is to achieve the above object of the invention：A kind of differential type is isolated to close two gear speed changes
Device, it is characterised in that including power input portion, power delivery section, variable part and case of transmission, wherein power inputs
Part connection external impetus, power delivery section connection Transmission Bridge band motor car wheel rotate, variable part by differential mechanism, clutch and
At least two one-way clutch form, wherein the sun gear A of the differential mechanism by the variable-speed shaft of differential mechanism through one-way clutch A
Install in planet carrier, remaining one-way clutch is arranged on the planet carrier of differential mechanism, and installation direction is in reverse gear
Work, do not work reversely, variable-speed shaft one end connection sun gear A other ends of differential mechanism connect clutch, and clutch is another
End is arranged on case of transmission.
The further technical scheme that the present invention uses is：The clutch is the clutch of ordinary clutch or locking,
The control mode of clutch is that hydraulic pressure is automatically controlled or manual.
The further technical scheme that the present invention uses is：The one-way clutch A installation directions are driven in forward gear
When work, do not work reversely, one-way clutch B installation directions are worked in reverse gear, are not worked reversely；It is single
It is opposite with one-way clutch B installation directions to clutch A installation directions.
The further technical scheme that the present invention uses is：It is that input shaft or input shaft add primary speed-down in power input portion
Gear, power delivery section are that output shaft or output shaft add primary speed-down gear.
Had the advantages that using a kind of isolated two shift transmissions that close of differential type of the present invention：
1. a kind of isolated variable part for closing two shift transmissions of differential type of the present invention is by differential mechanism, clutch and at least two
One-way clutch forms, and need not be controlled after being installed due at least two one-way clutch according to the automatic work of steering,
Only need to control clutch during gearshift, therefore the i.e. controllable upshift of an only control element and downshift, control are simple.
The variable-speed shaft that a kind of sun gear A of the isolated differential mechanism for closing two shift transmissions of differential type of the present invention passes through differential mechanism
Connected through one-way clutch A with planet carrier, it is possible to achieve forward gear, directly clutch can be controlled to connect during upshift
Close, without interrupting power and will not produce impact, therefore power does not interrupt during gearshift.
Two shift transmissions that close isolated to a kind of differential type of the present invention are described further with reference to the accompanying drawings and examples.
