Description
Technical field
The present invention relates to new energy power drive technical field more particularly to a kind of double-motor driving devices.
Background technique
Dual-motors Driving technology is following 10 years mainstream power drive technologies, and electric car not only can be improved is
System working efficiency, can also improve accelerating ability, operating characteristics and the working efficiency of vehicle, to improve course continuation mileage.
Currently, Dual-motors Driving technology mainly has following three kinds of implementations:
The first is to realize " 1+1=using two with type and with the motor of power with same speed and same Power operation
2 " effect.But the program has no theoretical performance or cost advantage, just with market situation, is suitable for two sets of small power electrics
Electrical Control price is lower than the automatically controlled price of a set of heavy-duty motor or the automatically controlled unavailable situation of heavy-duty motor.
Second is bridge driving, a responsible rear bridge driven before a motor is responsible for by the way of wheel coupling.This pair
Motor drive mode generally uses motor of the same race, mainly using 4 wheel driven as attraction, but has no odds for effectiveness.The program utilizes front and back wheel
Coupling loses efficiency, increases tire wear, practical application effect is bad.And the program needs two power vehicle bridge, increases
Cost and weight.
The third is then using two motors of the same race, and one is responsible for control high velocity, and one is responsible for control low regime, generally
Two motors are run with friction speed.Such mode utilizes the respective efficient operation interval of two motors, improves vehicle
Efficiency.But speed change, clutch and locking device are needed, whole complexity, weight and cost are increased.
The design and manufacture of China's gearbox and international most advanced level have larger gap, it is difficult to it is efficient to form large-scale low-cost
The product of rate, so, in the important period that subsidy decline, technical threshold are substantially improved, how to carry out technological innovation, optimization vehicle
Performance reduces the critical issue that production cost has become new-energy automobile industrial chain urgent need to resolve.
Patent dual-motor drive system (Granted publication CN203221879U) discloses a kind of dual-motor drive system,
It include: the first motor, the second motor, gearbox, the first of the output shaft of first motor and the gearbox is defeated
Enter axis connection, the second input axis connection of the output shaft of the second motor and the gearbox, the gearbox is interior to be equipped at least 3
Structure is kept off, even number gear is distributed on the first input shaft of gearbox, and odd number gear is distributed on the second input shaft of gearbox, described
Synchronizer connection is kept off by even number between even number gear, passes through odd number gear synchronizer connection between the odd number gear.Pass through above-mentioned side
Formula, the utility model structure is simple, and shift can be realized in no-clutch, it is easy to accomplish, control is combined by the driving of two motors
System, can be realized the optimum organization of dynamic property and economy；And shift is realized by bi-motor switching control, power failure-free,
Comfort is good.But there are still following disadvantages for the patent:
1, still need and connect with synchronizer, and synchronizer is equivalent to Miniature clutch, still needs to mechanical structure to separate electricity
Machine.
2, its gearbox for needing 3 grades or more, then it represents that it is motor of the same race, is arranged to different revolving speeds, it can not be using not
The characteristics of motor of the same race has complementary advantages.
3, using the structure in the patent, it is impossible to accomplish " power failure-free, smoothness run " completely, because with synchronizing
Device cuts out motor, and synchronizer is exactly that speed different axis in both sides is drawn to identical speed and angle of articulation, so will affect
Flatness, than using the effect of single motor poor.
4, the patent essence advantage is a motor optimization low speed, a motor optimization high speed, in this way in high speed and low speed
When one motor operation it is bad or even when cannot run, resultant force cannot be formed.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of double-motor driving device.
The present invention adopts the following technical scheme:
A kind of double-motor driving device, including reduction gearbox；The first motor being connect with the reduction gearbox；With the reduction gearbox
Connection, and it is different from the second motor of the first motor；Wherein, the first motor can drive second motor to turn
It is dynamic.
Preferably, the first motor and second motor are respectively arranged at the two sides of the reduction gearbox, and described first
The output shaft of the output shaft of motor and second motor is connect with the transmission gear in the reduction gearbox, the first motor and
Second motor is connected separately with the controller for driving its start and stop.
Preferably, the first motor and second motor are all set in the side of the reduction gearbox, and described
One motor and second motor are used with output axis connection, which connect with the transmission gear in the gear-box, institute
It states first motor and second motor is connected separately with the controller for driving its start and stop.
The invention has the following advantages: double-motor driving device of the invention using different types of two motors with
Same speed drives jointly, different using two class electric efficiencies and power interval, plays the advantage operation interval of different motors, excellent
Working condition can be adjusted flexibly by changing system cost and performance, bi-motor, not need big motor, two small machines just being able to satisfy property
It can index request, reduction system weight and development cost.

The rotation of two motors 3.
First motor 2 and the second motor 3 are respectively arranged at the two sides of reduction gearbox 1, the output shaft of first motor 2 and the second electricity
The output shaft of machine 3 is connect with the transmission gear 4 in reduction gearbox 1, and first motor 2 and the second motor 3 are connected separately with and it driven to open
The controller 5 stopped.
The working principle of the present embodiment:
It is magneto with first motor 2, for the second motor 3 is AC induction motor, based on magneto, with friendship
Stream asynchronous machine is driven jointly by fixed speed ratio, is not necessarily to clutch, speed change and locking device.Magneto is high-efficient, low speed torque
Relatively low, high torque is big, has resistance to have counter electromotive force when dragged；And AC induction motor low speed torque is big, high torque is inclined
Small, non-resistance is without counter electromotive force when dragged.
Electric vehicle is driven to travel always with magneto, in the case where needing to increase torsion, AC induction motor is situated between again
Enter driving, by the start and stop of controller control magneto and AC induction motor, since AC induction motor is with the drive of magnetic field differential
Dynamic magneto is not strict with the electrical rotate-speed and intervention phase of intervening node, is easy to AC induction motor by control
The needs of algorithm processed switch in and out, and torque is adjusted when generally switching in and out and is close to zero.
Low power applications can only use magneto；High power applications, especially starting accelerate and add when climbing
AC induction motor；High speed also can according to need when running is added AC induction motor for increasing torque and power；
Power demand can stop the driving of AC induction motor when declining, reduce drive loss.At this time without using clutch etc
Mechanical structure separation AC induction motor without counter electromotive force non-resistance when AC induction motor is dragged will not generate loss.
