Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is described in further detail, described in be to this utility model
Explanation rather than restriction.
This preferred embodiment is as it is shown in figure 1, there are two power sources, and respectively M1 power source 13, M2 power source 14, power source can
It is configured to motor.Power is inputted by first power shaft the 3, second power shaft 11 respectively.It is provided with empty set on first power shaft 3
1 grade of gear 6 of power shaft on axle, 2 grades of gears 4 of power shaft, the number of teeth is respectively Z1, Z2, and 1/2 grade of lock unit 5 is arranged on input
Between 1 grade of gear of axle, 2 grades of gears of power shaft, synchronizer sliding sleeve gear moves axially realization and engages with 1,2 grades of gears；Second is defeated
Enter and on axle 11, be provided with the 3 grades of gears 12 of power shaft connected firmly with axle, tooth number Z 3；First power shaft, the second power shaft rear and front end
It is arranged on case of transmission 1 by rolling bearing respectively.Be disposed with from right to left on output shaft 8 with the first power shaft,
1 grade of gear 9 of the output shaft that on second power shaft, each shelves gear is meshed, 2 grades of gears 10 of output shaft, 3 grades of gears 2 of output shaft, tooth
Number is respectively z1, z2, z3, and output shaft each shelves gear is fixedly connected with output shaft, and output shaft 8 rear and front end is respectively by rolling
Bearing is arranged on case of transmission 1.
This preferred embodiment arranges two gears, respectively low or first gear and top gear altogether.
As in figure 2 it is shown, vehicle launch and when running at a low speed, i.e. bottom gear.Gearbox controller (AMT) stirs 1/2 grade together
Step device sliding sleeve slides to the right, and 1 grade of gear engagement of power shaft on the first power shaft, power is transferred to power shaft by the first power shaft
1 grade of gear, then after being transferred to 1 grade of gear of output shaft, pass to ring flange 7 by output shaft.Assume that power source M1 rotating speed is N1,
The rotating speed of ring flange is:
Now in order to increase power output, it is thus achieved that higher acceleration or climbing capacity, power source M2 exports power.Electricity
Machine controller calculates the rotating speed needed for power source M2 and torque, in order to mate, the output of M2 with power source M1 according to current vehicle speed
Rotating speed is:
Power is transferred to 3 grades of gears of power shaft by the second power shaft, then after being transferred to 3 grades of gears of output shaft, by defeated
Shaft passes to ring flange, it is achieved power collaborates.
As it is shown on figure 3, during high vehicle speeds, i.e. top gear.Power source M1 disconnects, and power source M2 normally works, now
Power is transferred to 3 grades of gears of power shaft by the second power shaft, then after being transferred to 3 grades of gears of output shaft, is transmitted by output shaft
To ring flange.Assuming that power source M2 rotating speed is N2, the rotating speed of ring flange is:
Gearbox controller motor is stirred 1/2 grade of lock unit sliding sleeve and is slided to the left, 2 grades of gears of power shaft on the first power shaft
Engagement, power source M1 exports power.Electric machine controller calculates the rotating speed needed for power source M1 and torque according to current vehicle speed, in order to
Mating with power source M2, now the output speed of M1 is:
Power is transferred to 3 grades of gears of power shaft by the second power shaft, then after being transferred to 3 grades of gears of output shaft, by defeated
Shaft passes to ring flange, it is achieved power collaborates.
During bottom gear liter top gear is whole, ring flange is provided power by power source M2 all the time, reaches shifting up operation
The purpose of power failure-free.On the contrary when variator is dropped low or first gear from top gear by needs, power source M1 disconnects, and power source M2 is just
Often working, gearbox controller motor is stirred 1/2 grade of lock unit sliding sleeve and is slided to the right, 1 grade of gear of power shaft on the first power shaft
Engagement, power source M1 exports power again, and downshift process also realizes power failure-free.
This preferred embodiment carry out neutral and reverse gear traveling time.
When 1/2 grade of lock unit sliding sleeve is in an intermediate position, and power source M2 does not export power, i.e. neutral.
As it was previously stated, variator is in low or first gear, the reverse input power of power source M1, M2, i.e. realize reversing gear.
When this utility model is specifically used, works including the power source controlling to be connected with the second power shaft, make this power source
Power is transmitted, it is achieved the step that power persistently exports to output shaft；And control the power source work being connected with the first power shaft,
The power shaft shifting gear making this power source be selected by gear shift mechanism transmits power to output shaft, it is achieved the step of gear switch
Suddenly.
The power source that can also control the second power shaft connection quits work, and gear shift mechanism selects neutral gear position, it is achieved
The step of neutral.And control to provide reverse power with two power sources, make the power source being connected with the second power shaft work to
Output shaft direction of transfer power, makes the power source being connected with the first power shaft by the power shaft shifting gear of low-grade location to output
Axle transmission power direction power, it is achieved the step reversed gear.
