Description
Technical field
The present invention relates to electrical vehicular power transfer device, especially a kind of two grades of the 4th gear single-direction transmission of no reverse gear automatic
Speed changer.
Background technique
Since electric vehicle driving cycle difference causes speed difference bigger, electronic function is needed if without speed changer
The wider range of speeds is enough exported, very high to the performance requirement of motor, motor efficient operation section is limited, if motor exists
Low-power consumption regional work, energy consumption is larger, reduces electric car cruising ability.Although the performance of motor is better than engine, it is not required to
It to configure the speed changer of multi gear position like that engine, but at least be also required to be able to achieve the two of high and low shelves work with one
Gear automatic speed variator.Existing two speed transmission or gear shift is dynamic to interrupt or needs two control clutches to realize
Gear shift, clutch unclamp, the engagement of another clutch, due in order to when power do not interrupt, there are no complete for a clutch
When full release, another clutch will be engaged, and cause two clutches that there is certain working sequence to be overlapped compared with angle in this way,
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 a clutch
Device is not, it can be achieved that power interrupts gear shift.
Current automatic speed derailleur for electric vehicle or gear shift power interruption known to analyzing above, slip by slope when going up a slope
Phenomenon or clutch, which are prone to wear, is exactly that poor reliability or technology are not mature enough, therefore two-shift automatic variable speed device on the market
It is promoting and applying and few.
Summary of the invention
It is limited the purpose of the invention is to overcome and solve existing electric vehicle electric machine efficient operation section, existing two grades
Automatic transmission or there is gear shift power interruption, occurs slipping by slope phenomenon when going up a slope or clutch is prone to wear poor reliability
The shortcomings that and problem, a kind of the 4th gear single-direction transmission two-shift automatic variable speed device of no reverse gear is provided, to realize the work of electronic function
In efficient operation region.
To achieve the above object of the invention the technical solution adopted by the present invention is that: a kind of no the 4th gear single-direction transmission two of reverse gear
Gear automatic speed variator, it is characterised in that including input shaft 1, gear A 2, gear B 3, one-way clutch 5, output shaft 8, clutch 6,
Gear C 7, jackshaft 4, gear D 9, wherein the gear A 2 is fixedly mounted on input shaft 1, output shaft 8 passes through with jackshaft 4
Clutch 6 connects, and gear B 3 is mounted on jackshaft 4, and gear C 7 is mounted on input shaft 1, passes through one-way clutch on output shaft 8
Device 5 is equipped with gear D 9；The gear A 2 is engaged with gear B 3, and gear C 7 is engaged with gear D 9；The output shaft 8 and jackshaft
4 be in straight line, and output shaft 8 is parallel with input shaft 1；The ratio of the number of teeth of the number of teeth and gear B 3 of the gear A 2 is greater than gear
The ratio of the C7 number of teeth and 9 number of teeth of gear D, gear C 7 and gear D 9 realize one grade of transmission of advancing, the output shaft when clutch 6 works
8 connect with jackshaft 4, and gear A 2 engages two grades of transmissions of realization advance with gear B 3, and the clutch 6 is ordinary clutch or band
The clutch of locking, control mode are hydraulic or automatically controlled.
The further technical solution that the present invention uses is: 5 installation direction of one-way clutch be when advancing one grade of transmission from
Effect, does not work reversely.
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 no the 4th gear single-direction transmission two-shift automatic variable speed device of reverse gear of the present invention
1. a kind of no the 4th gear single-direction transmission two-shift automatic variable speed device of reverse gear of the present invention use a clutch 6 for commonly from
The clutch and an one-way clutch of clutch or locking are not needed control basis and turned after being installed due to one-way clutch
It to automatic work, therefore only needs in gear shift to control clutch 6 and lifting shelves can be realized, control element is few, and control is simple.
2. the present invention a kind of number of teeth and gear of the gear A 2 of no the 4th gear single-direction transmission two-shift automatic variable speed device of reverse gear
The ratio of the number of teeth of B3 is greater than the ratio of 7 number of teeth of gear C and 9 number of teeth of gear D, therefore 5 installation direction of one-way clutch is preceding
It into working when one grade of transmission, does not work reversely, the engagement of clutch 6 can be directly controlled in this way in shifting up operation, without
It needs to interrupt power and impact will not be generated, therefore gear shift effect and 6 long service life of clutch.
With reference to the accompanying drawings and examples to a kind of no the 4th gear single-direction transmission two-shift automatic variable speed device of reverse gear of the present invention
It is described further.
