Description
Technical field
The invention belongs to pure electric vehicle power transmission fields, and in particular to a kind of double jackshafts of pure electric vehicle bi-motor input
Variator scheme.
Background technique
As the day of oil consumption, emission regulation is increasingly tight, the fuel power of orthodox car is faced with severe challenge.Hold the whole world
Energy revolution development trend and CHINESE INDUSTRIES Green Transformation demand for development have Ecological Civilization Construction and reply climate change in mind, with
Green low-carbon technological innovation and application are attached most importance to, and green consumption is guided, and promote green product, wherein pure electric vehicle is new energy vapour
The important component of vehicle, energy conservation and reliability are the critical evaluation indexs of pure electric vehicle.
For pure electric vehicle, distributed driving and central type driving can be simply divided into from structure；Central type driving
Main component is exactly single motor or bi-motor adds speed changer or retarder.
The scheme of bi-motor input plus double intermediate gearboxs, both may be implemented the power dividing of motor, and also may be implemented to become
The power dividing of fast device.It is inputted by the power of bi-motor difference speed ratio, cooperates the speed ratio of two speed transmission, efficiently meet vehicle
Driving and braking power demand.Meanwhile double jackshaft two speed transmission axial dimensions are short, stable drive, suitable tooth is hitched
Gear.
Summary of the invention:
The present invention be based on more than technical background, propose a kind of input twin countershaft transmission transmission of pure electric vehicle bi-motor
Scheme., the program combines the input of bi-motor Dual-speed-ratio and the advantages of twin countershaft transmission, realizes power input to machine shunting
While, also achieve the power dividing of variator.System structure is simple, and axial dimension is short, and power transmission is steady, is suitble to
Tooth set is put into gear.The Dual-speed-ratio of motor input efficiently meets the power of vehicle traction and braking in conjunction with the speed ratio of two speed transmission
Demand.
The technical solution adopted by the present invention are as follows: a kind of pure electric vehicle bi-motor input twin countershaft transmission transmission scheme,
Including the identical motor 1 of two power and motor 2, and respectively by two electromagnetic clutch Clc1 and Clc2 and transmission gear with
Transmission input shaft is connected；The separation of the electromagnetic clutch combines the separation and combination that can control motor and speed changer.
Further, the input speed ratio of the motor 1 isi1, the input speed ratio of motor 2 isi2, andi1≠i2；
Further, the main shaft of the twin countershaft transmission can float and use and be put into gear using sliding sleeve.
The beneficial effect comprise that: the input of bi-motor Dual-speed-ratio is in conjunction with twin countershaft transmission in the present invention
Transmission scheme realizes double applications of the intermediate gearbox on bi-motor Dual-speed-ratio input structure, combines the excellent of two kinds of structures
Point.Both it realizes multiple gear ratios, efficiently meets the needs of vehicle traction and braking, while engaging gear structure is simple and reliable, success rate is high.
Detailed description of the invention
Fig. 1 is transmission principle figure of the invention.
Specific embodiment
A specific embodiment of the invention is further described with reference to the accompanying drawing.
The invention belongs to a kind of pure electric vehicle bi-motors to input twin countershaft transmission transmission scheme, mainly include two
The identical motor 1 of power and motor 2 are used as input power, and motor 1 and motor 2 make relative to twin countershaft transmission entering spindle
With different input speed ratiosi1Withi2.Including the identical motor 1 of two power and motor 2, and pass through two electromagnetic clutch respectively
Device Clc1 and Clc2 and transmission gear are connected with transmission input shaft.Twin countershaft transmission is put into gear using sliding sleeve.Slide over behaviour
Under the control of vertical mechanism, operation of putting into gear can be realized.
When vehicle traction, two input motors carry out reasonable torque distribution, work alone or synergistically.Pair of motor input
The speed ratio of speed ratio combination twin countershaft transmission realizes multiple speed ratios, high efficiency drive vehicle.When vehicle braking, double jackshafts become
Fast device fixes a speed ratio, and two motors are distributed by Dual-speed-ratio and torque, maximizes Brake energy recovery efficiency.
It is noted that above-described embodiment is to the illustrative and not limiting of technical solution of the present invention, technical field is general
The equivalent replacement of logical technical staff or the other modifications made according to the prior art, as long as not beyond technical solution of the present invention
Thinking and range should be included within interest field of the presently claimed invention.
