Specific embodiment
Fig. 1: the heteropleural face-off double dynamical hybrid system schematic diagram of mechanism of concentric shafts
It is as shown in the figure: to be connected respectively with transmission input shaft A, transmission input shaft B by motor A, the motor B of heteropleural face-off
It connects, two axis can connect or be disconnected by double acting mechanical couple (synchronizer or clutch) 6, between two axis and output shaft 12 respectively
It is separately installed with a shelves gear pair 3, third gear pair 5, fourth gear pair 7, intermediate gear pair 9, and it is same to pass through one, third gear respectively
Step device, two, the control of fourth gear synchronizer can change variator power flow path.
Its working principle and control logic relationship illustration are as follows:
It being illustrated starting at from one grade of work, synchronizer puts in the first speed, and motor A work, power flow is exported by a shelves gear pair, this
It carves, if necessary to high-power output, motor A, motor B are worked at the same time, and double acting mechanical couple (synchronizer or clutch) 6 connects,
Bi-motor power flow merges to be exported by a shelves gear pair.
Two grades are hung, it can be there are three types of control strategy:
Strategy 1: first confirm that double acting mechanical couple 6 disconnects this moment, motor A elder generation speedup, when output shaft revolving speed being allowed to reach two grades
(note: two grades of revolving speeds are relative value to corresponding output revolving speed at this time, refer to that motor B revolving speed does not raise speed under current state
Preceding corresponding two grades of output revolving speed), at this point, the combined cover and conjunction gear revolving speed of two grades of corresponding synchronizers are synchronous, it is linked into two grades
(high-power if necessary, then motor A revolving speed can be allowed to restore, and combine double acting mechanical couple 6).
Strategy 2: first confirming that double acting mechanical couple 6 disconnects, and motor A revolving speed is constant, and motor B slows down, and drops to and allows two grades of correspondences
Synchronizer combined cover and conjunction gear revolving speed it is synchronous, be linked into two grades, later, disengage one grade of synchronizer, allow motor B speedup to former
Revolving speed, then speed changer output is two grades of revolving speeds, and two axis reach synchronous this moment, if necessary to high-power, then allows double acting mechanical couple 6
In conjunction with bi-motor while output power.
Strategy 3: if needing high-power upshift speedup at present, allowing double acting mechanical couple 6 to combine, and allows and bi-motor while joining
With work, while speedup, the output of one shelves gear pair of power flow merga pass, allow output shaft revolving speed when reaching two grades corresponding output turn
When fast, double acting mechanical couple 6 is disconnected, and motor B slows down, synchronous when the combined cover and synchronous conjunction gear revolving speed of two grades of synchronizers
Device combines, and is linked into two grades.If necessary to high-power, then one grade of synchronizer is disconnected, motor A is allowed also to slow down so that two motor speeds are same
After walking device, double acting mechanical couple 6 is allowed to combine, bi-motor while output power.
It hangs third gear, hang fourth gear, principle is same as above, is not introducing one by one.
Note: if necessary to high-power, can allow two motors to work at any time, allow double acting mechanical couple 6 if revolving speed is synchronous
It keeps combining, passes through the corresponding gear pair output power of same synchronizer.It, can also be by disconnected if two motor speeds are asynchronous
Double acting mechanical couple 6 is opened, bi-motor different rotating speeds is adjusted to obtain and exports same rotating speed by different synchronizer corresponding teeth wheel sets,
High-power in the output of output shaft cocurrent, control strategy is that the two revolving speed revolving speed when reaching output shaft is synchronous, is mutually adapted and does not send out
Existing revolving speed interference phenomenon is principle.
To guarantee synchronizer service life and energy consumption problem, comfortableness problem, when shift power flow switches, it should be ensured that synchronizer
It combines or separates under the premise of off-load, elastic reset shaft coupling or freewheel clutch can be increased, this working principle can refer to formerly
Patent application (application number: 201810007008.9；201810087621.6).
Analysis: in above-mentioned control strategy 2, motor A remains that revolving speed is constant, this control strategy is dynamic suitable for wherein one
Power source is the power source scheme that can not be adjusted the speed.
Note 1: motor A, motor B can be with role exchanges.
Note 2: motor A, motor B can be bi-motor, twin-engined or in which one is engine, be respectively combined in pairs
Motor mode, the double acting force mode of conventional engines or hybrid mode.
In addition, this bi-motor is also possible to traditional combustion engine, hydraulic motor, air motor, steam engine, gas turbine, sky
Pneumatic force engine, the power sources such as compressed air engine.
In its dual power source, at least one power source is the power source that can be adjusted the speed.Or dual power source can adjust the speed.
In addition, can according to output power demand size is used single power source work or dual power source work at the same time.
Fig. 2: the ipsilateral double dynamical hybrid system schematic diagram of mechanism of parallel axes
Its working principle is similar with Fig. 1, and the two difference is space layout difference, is laid out for parallel axes, the power flow of two axis
Linking need to add idle pulley with sprocket wheel chain or gear to complete.In addition, two motors can also be arranged in heteropleural, such as: motor A can be with
The right end of transmission input shaft A is set.
Fig. 3: the double dynamical hybrid system schematic diagram of mechanism of two grades of ipsilateral concentric shafts
Fig. 3 show the ipsilateral concentric shafts placement scheme of bi-motor, and in this scheme, there are hollow shaft, solid shafting, concentric shafts couplings
Close synchronizer and sleeve rotor motor D.This space layout is very compact.Working principle with above it is similar, no longer introduce one by one.
