Description
Technical field
The present invention relates to automobile power transfer device, especially a kind of single clutch two-shift automatic variable speed device for having reverse gear.
Background technique
Since Electric Vehicles Driving Cycle difference causes speed difference bigger, motor is needed if 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 car cruising ability.Although the performance of motor is better than engine, no
It needs to configure the speed changer of multi gear position like that engine, but is at least also required to be able to achieve high and low shelves work with one
Two gear automatic speed variators.The dynamic interruption of existing two speed transmission or gear shift or two control clutches of needs are real
Existing gear shift, a clutch unclamp, and the engagement of another clutch, in order to which in gear shift, power is not interrupted, a clutch does not have also
When being totally released, another clutch will be engaged, and cause two clutches that there is certain working sequence to be overlapped in this way
Compared with angle, it is easy to produce the final service life for influencing clutch of friction.Two-shift automatic variable speed device of the invention only needs to control one
A clutch is not, it can be achieved that power interrupts gear shift.
By power interruption when current electric car automatic speed transmission known to analyzing above or gear shift, occur when going up a slope
It slips by slope phenomenon or clutch is prone to wear, service life is short, poor reliability, therefore two-shift automatic variable speed device pushes away on the market
It is extensively applying and few.
Summary of the invention
It is limited the purpose of the invention is to overcome and solve existing electric automobile motor efficient operation section, existing two
Gear automatic speed variator or there is gear shift power interruption, occurs slipping by slope phenomenon when going up a slope or clutch is prone to wear reliability
The disadvantage and problem of difference, provide a kind of single clutch two-shift automatic variable speed device for having reverse gear, to realize electronic function work in height
Imitate working region.
To achieve the above object of the invention the technical solution adopted by the present invention is that: two grades of a kind of single clutch having reverse gear are automatic
Speed changer, it is characterised in that including input shaft 1, gear A 2, gear B 3, one-way clutch A4, output shaft 5, clutch 6, gear
C7, jackshaft 8, gear D 9, one-way clutch B10, one-way clutch C11, gear E12, gear F13, wherein the gear A 2
Be fixedly mounted on input shaft 1, input shaft 1 and jackshaft 8 are connect by clutch 6, gear B 3 is pacified by one-way clutch A4
On output shaft 5, gear C 7 is mounted on jackshaft 8 by one-way clutch B10, and gear E12 is mounted on jackshaft 8,
Gear D 9 is also fixedly installed on output shaft 5, gear F13 is mounted on output shaft 5 by one-way clutch C11；The gear
A2 is engaged with gear B 3, and gear C 7 is engaged with gear D 9, and gear E12 is engaged with gear F13；The input shaft 1 is in jackshaft 8
Straight line, output shaft 5 are parallel with input shaft 1 and jackshaft 8；The transmission ratio of the gear A 2 and gear B 3 be greater than gear C 7 with
The transmission ratio of gear D 9, gear A 2 and gear B 3 realize one grade of transmission of advancing, and gear C 7 and gear D 9 realize two grades of transmissions of advancing,
Gear E12 and gear F13 realizes reverse gear.
The further technical solution that the present invention uses is: the clutch 6 for ordinary clutch or the clutch of locking,
Control mode is hydraulic or automatically controlled.
The further technical solution that the present invention uses is: the one-way clutch A4 installation direction is in one grade of transmission of advancing
When work, do not work reversely, one-way clutch B10 installation direction is worked when advancing two grades of transmissions, is not risen reversely
Effect, one-way clutch C11 installation direction is worked in reverse gear, is not worked reversely；Wherein one-way clutch A4
Installation direction is identical as one-way clutch C11 installation direction opposite with one-way clutch B10 installation direction.
The further technical solution that the present invention uses is: its feature further includes adding primary speed-down tooth in input shaft or output shaft
Wheel.
It is had the advantages that using a kind of single clutch two-shift automatic variable speed device for having reverse gear of the present invention
1. a kind of single clutch two-shift automatic variable speed device for having reverse gear of the present invention use a clutch 6 for ordinary clutch or
The clutch of locking and three one-way clutch do not need control according to steering after installing due to three one-way clutch
Automatic work, therefore only need to control clutch 6 in gear shift, control element is few, and control is simple.
2. the gear A 2 and the transmission ratio of gear B 3 of a kind of single clutch two-shift automatic variable speed device for having reverse gear of the present invention are big
In the transmission ratio of gear C 7 and gear D 9, therefore one-way clutch A4 installation direction is worked when advancing one grade of transmission, instead
To not working, the engagement of clutch 6 can be directly controlled in this way in shifting up operation, without interrupting power and will not generate
Impact, therefore gear shift effect and clutch long service life.
3. gear E12 and gear F13 realizes reverse gear, due to relatively more independent, so reverse gear ratio can flexibly be set
Meter.
A kind of single clutch two-shift automatic variable speed device for having reverse gear of the present invention is made into one with reference to the accompanying drawings and examples
Walk explanation.
