Specific embodiment:
The present invention is explained in detail with reference to the accompanying drawing:
Refering to fig. 1, multiaxis drive system of hybrid power vehicle includes hydraulic motor 1, wheel 2, generator control driver
3, electrical source of power 4, Motor Control driver 5, rear driving axle 6, motor 7, motor 7, switchover apparatus 8, planet row
Mechanism 9, switchover apparatus 10, generator 11, clutch 12, power takeoff 13, engine 14, hydraulic pump 15, hydraulic valve bank 16,
Fluid pressure line 17, hydraulic accumulator 18.Wherein hydraulic motor 1 is wheel hub hydraulic motor；Switchover apparatus 10 is generator
Power switches between drive axle and the sun gear of planet row；Switchover apparatus 8 is the power of motor in drive axle
It is switched between the gear ring of planet row.
Referring to Fig.2, illustrating switchover apparatus details, switchover apparatus 10 includes synchromesh gear 20, switching synchronization
Ring 21, change gear 35, synchromesh gear 34, sun wheel shaft 33, main reducing gear 36, differential mechanism 37；Switching device 8 includes synchronous gear
Wheel 24 switches synchronous ring 28, change gear 29, synchromesh gear 27, main reducing gear 38, differential mechanism 39；Dynamic and planet row transmission knot
Composition.Wherein synchromesh gear 20 and synchromesh gear 27 distinguish empty set in generator power output shaft 19 and motor power output shaft
On 26, generator power output shaft 19 is hollow shaft, and engine power output shaft 22 is from 19 center of generator power output shaft
It passes through, and connects the planet carrier of planet row, motor power output shaft 26 is hollow shaft, and planet row gear ring power output shaft 25
It is passed through from 26 center of motor power output shaft, and connects rear driving axle 6.The powershift principle of switchover apparatus is similar to
Tradition machinery shift of transmission principle, when the synchronous ring 21 of switching is stirred to the left, at this moment since the effect for switching synchronous ring can make
It obtains change gear 35 and synchronizes rotation with the synchromesh gear 20 of empty set, is i.e. the power of generator has passed to synchromesh gear
20, to drive third drive axle；When the synchronous ring 21 of switching is stirred to the right, at this moment since the effect for switching synchronous ring can make
It obtains change gear 35 and synchromesh gear 34 synchronizes rotation, is i.e. the power of generator has passed to synchromesh gear 34, to drive
Sun gear 32 and engine and motor unit in dynamic planet row synthesize series-parallel hybrid electric system.Ring 28 is synchronized when switching
When stirring to the left, at this moment due to switching the effect meeting of synchronous ring so that change gear 29 is carried out with the synchromesh gear 24 of empty set
It rotates synchronously, i.e. the power of motor passed to synchromesh gear 24, to drive gear ring in planet row and engine and hair
At this moment motor combination synchronizes the work of ring when the synchronous ring 28 of switching is stirred to the right at series-parallel hybrid electric system due to switching
With meeting so that change gear 29 and synchromesh gear 27 synchronize rotation, i.e. the power of motor has passed to synchromesh gear 27,
To the 4th drive axle of driving.It is worth noting that when switching synchronous ring 21 and stirring to the left, the power drive of generator the
When three drive axles, at this moment the sun gear of planet row is in free rotation state, it is therefore necessary to pass through brake (synchromesh gear 34
It is right) locking is carried out to sun gear, engine could be by the 5th rear axle of planet row back kick graduating power and driving.
Refering to Fig. 3, the main reducing gear and differential mechanism of drive axle are considered a part of the two switchover apparatus, wherein
The corresponding drive axle of switchover apparatus 10 is shown in a figure left side, and the corresponding drive axle of switchover apparatus 8 is shown in the figure right side.36,
38 be main reducing gear, and 37,39 be differential mechanism, and wherein the input terminal of main reducing gear 36 is synchromesh gear 20, main reducing gear 38 it is defeated
Entering end is synchromesh gear 27.It is worth noting that due to main reducing gear be hyperboloid tooth wheel decelerator, main reducing gear input shaft and
Spatially there is eccentricity, therefore differential mechanism and main reducing gear input shaft under the conditions of certain big main reducing gear in output shaft
Interference will not be generated between (i.e. motor power output shaft or motor power output shaft).
Refering to Fig. 4 and Fig. 5, in Fig. 4, as can be seen that generator power output shaft drives row from switchover apparatus
The sun gear of star row, motor power output shaft drives the gear ring of planet row, in Fig. 5, i.e., for according to Fig. 4 switchover apparatus
Simplified power transmission configuration picture.As can be seen that in this mode, rear axle is operated alone, engine, motor, generator
Three power sources form series-parallel hybrid electric system by planet row, and wherein wheel hub fluid power system passes through to hydraulic valve bank
It is controlled, so that hydraulic motor does not export energy and do not absorb energy yet, hydraulic motor is under bypass state；Generator it is same
Step gear is synchronous with the sun gear of planet row, and the synchromesh gear of motor and the gear ring of planet row are synchronous, i.e. engine connection row
Carrier, generator connection sun gear, motor connect gear ring, drive the 5th driving eventually by gear ring center axis output power
Bridge, generator and motor cooperate engine operation according to corresponding operating condition, utilize the section of hybrid drive system in type of multiple series connection
Oily advantage can give full play to its fuel economy under multiaxle trucks vehicle working condition.Under normal circumstances, vehicle operation is at this
Under mode, fuel economy is improved as far as possible.
Refering to Fig. 6 and Fig. 7, in Fig. 6, as can be seen that generator switches power from switchover apparatus, driving is driven
Bridge (third drive axle), motor also switches power, and then drives drive axle (the 4th drive axle), the sun in planet row
Wheel is locked up, and engine drives the 5th drive axle, as can see from Figure 7, power after planet row carries out speed ratio shift
Switching device A is the dotted line frame part A in Fig. 6, input of the generator power output shaft as switchover apparatus A, third
Output of two semiaxis of a drive axle as switchover apparatus A, switchover apparatus B is dotted line frame part B in Fig. 6,
Two semiaxis of input of the motor power output shaft as switchover apparatus B, the 4th drive axle are filled as powershift
Set the output of B；Meanwhile the addition of hydraulic hub drive system, so that the first drive axle and the second drive axle are by the hydraulic horse of wheel hub
Up to driving；As can be seen that in this mode, vehicle is in a11wheel drive state, wheel hub hydraulic motor, engine, power generation are mechanical, electrical
Motivation respectively drives the first and second drive axles, third drive axle, the 4th drive axle, the 5th drive axle, in this case, vehicle
Maximum driving force is obtained, enables to vehicle that there is stronger passage capacity.
Refering to Fig. 8, since rear axle is operated alone, generator, motor, three power source of engine cooperate planet row, so that
