Description
Technical field
The present invention relates to electric automobiles, more particularly, to a kind of electric car side hanging bi-motor deceleration box.
Background technology
Electric car is due to low-carbon, energy saving, use cost is light, deep to be liked by consumer.The current electric car owning amount in China is big
In 200,000,000, by the technological progress of more than ten years, battery-operated motor cycle, Development of Electric Vehicles progressively rise, and market is not therewith
Disconnected to expand, relevant battery-operated motor cycle standard, electric automobile standard are expected to put into effect quickly, and the requirement of user also constantly rises
Level, such as electric automobile requirement speed reaches the racing car of 75 horses and electric motorcycle and the quality of freight truck is not known
Property, known wheel hub electric motor of electric vehicle, differential speed motor technology, speed and moment of torsion are immutable, can not be satisfied with following electric vehicle
Particular/special requirement, the prior art needed for such as climbing load in the case of large torque, often shows in special operational process
It is bad even to shut down, especially loaded under conditions of vehicle needs premised on speed unable to do what one wishes, unique solution is
Amplifying power.
To solve the performance strength of vehicle bigger in operation, Dual-motors Driving pattern has been begun attempt in field, such as
Say wheel hub motor, when single motor undercapacity, start auxiliary-motor work, but this designing scheme is the list for sacrificing normal operation
Electric efficiency is preceding topic.Therefore, technical staff will start to expand side-mounted high-speed electric expreess locomotive research, such as Patent No.
The driving device Chinese invention patent of 200610138450.2 electric motor car with two wheels, just proposed major-minor motor and drives actively before 10 years
The transmission scheme of gear, the technology employ main motor and auxiliary-motor output shaft and are nibbled respectively by respective gear with drive gear
Close, but this primary transmission can not allow auxiliary-motor to perform to more speed and bigger output torque due to the limitation of gearratio（Most
Big output torque is 70n.m）, since major-minor motor is arranged to same direction, in order to make major-minor motor reasonable installation, it has to allow
The unit volume of gearbox increases and increases production cost, and it is further perfect to need electric automobiles technical staff.

Further, secondary shaft seal circle hole and the correct centering of fourth bearing mounting hole.
Further, main shaft seal circle hole and the correct centering of clutch shaft bearing mounting hole.
In a kind of form, fuel outlet is formed with straight wall below babinet, fuel outlet can be used as carrying out when gear oil is replaced
Discharge sump oil.
A kind of electric car side hanging bi-motor deceleration box of the present invention, is a component of Dual-motors Driving assembly, passes through
The combination of case lid and babinet, forms bi-motor reduction box, deceleration box cavity installation gear assemblies, the double electricity of outside the enclosure portion installation
Machine, constitutes a kind of side hanging Dual-motors Driving assembly, Dual-motors Driving assembly is under the close fit of control system（Control system
The default driver of system）, the operational modes of different road conditions can be made automatically according to the road surface speed of service, for example, normal road surface
In traveling, system only controls main motor to be operated, and when load during starting with starting auxiliary-motor power-assisted, this drive pattern can be with
The power of main motor is set to apply all to speed, in the loaded state, double reduction connection of the auxiliary-motor through carrier gear is driven
Gear power-assisted, can obtain the gearratio of bigger, and compared with than 200610138450.2 patented technologies, the multiple with product increases torque,
Such as：The primary speed-down ratio of 200610138450.2 patented technologies is 2, and double reduction ratio of the present invention is 2 square, meanwhile, lead to
The setting of double reduction increase gearratio is crossed, the more high-revolving design of auxiliary-motor can be improved, accomplishes that small-volume large-power is saved
Cost is manufactured, more benefits from user, and the effect for saving the energy is brought for country.
