Currently, weather pollution and energy shortage are the two big challenges that the world today faces, to dioxy on the climate Conference of Paris
The annual discharge for changing carbon is just increasingly stringenter, and another aspect world structure is more nervous, and energy crisis is got over national security relationship
Come closer, this forces out the development of new type power to be also increasingly taken seriously, in terms of new-energy automobile, with the advantageous political affairs of country
Plan is weeded out the old and bring forth the new, so that new-energy automobile industry flourishes under various good policy supports, but due to now national to new
The adjustment of the raising year by year of energy threshold, double integrator and subsidies measures payes attention to vehicle increasingly the promotion of course continuation mileage.
Current main-stream vehicle is all made of front and back bi-motor arrangement in SUV vehicle, it is therefore an objective to promote hundred kilometers of acceleration capacities
And dynamic property.Since the motor adjustable-speed range of new-energy automobile is wide, new-energy automobile gearbox mostly uses a gear side
Case is two drive modes under number vehicle operating condition big absolutely.But problem is also following, if using a gear scheme,
Mean under two drive modes there can be a power assembly and not work, and be by anti-the case where dragging.Power assembly is dragged by counter,
Consequent is the loss of energy, and the reduction of vehicle efficiency significantly impacts the course continuation mileage of vehicle.If dragged by counter, tooth
Roller box is also easy to generate utter long and high-pitched sounds equal noises, and motor will appear the risk of back-emf.
Current line in the industry only a small number of enterprises can using two-speed transmission or increase clutch scheme come make power interruption with
In conjunction with, but Jue great main engine plants there is no mature technology to solve the problems, such as this.In addition as using two-speed transmission or increase clutch side
Case, control, space layout are technological difficulties, it is difficult to it is universal, and also required arrangement space is huge, and it is with high costs, with the row of reduction
It puts and increases new-energy automobile course continuation mileage target and run in the opposite direction.
Solenoid valve b15(Solenoid valve) it is a kind of executing agency controlled with electromagnetism, solenoid valve b15 work
Principle is that electric energy is converted to electromagnetic energy reconvert into mechanical energy.There are certain resistance by solenoid valve b15 itself, after given voltage
Electric current is generated, electric current makes coil generate magnetic force, and magnetic force moving executing agency is axially moved.Solenoid valve b15 main inside knot
Structure includes interface connector, electric wire, coil, cooling shell, external envelope shell and sports ring composition.
In new-energy automobile four-wheel drive, in order to drive four wheels, it is necessary to all wheels are connected, if
Four wheels are mechanically coupled together, and automobile cannot be rotated when curve driving with identical speed, in order to allow
At this moment the almost the same property of automobile curve driving rotation speed needs to be added rotational speed difference of the center differential to adjust front and back wheel.
The present invention be new energy consumption automobile specified disconnection differential mechanism, be arranged in the gearbox of new energy consumption automobile, by with main reducing gear
Wheel b3 is connected to be inputted as power, is connected by axle shaft gear b6 inside differential mechanism with vehicle semiaxis and is carried out power output.When
When needing 4 wheel driven function, vehicle instruction is issued, and electric machine speed regulation makes final gear b3 and wheel differential control within 40rpm,
Right solenoid valve b15 is powered, and then active connector b10 and slave link b8 is pushed to be combined, and power is transmitted by gearbox
To wheel；When not needing 4 wheel driven function, solenoid valve b15 power-off, differential mechanism reset spring b12 make active connector b10 and from
Follower link b8 is disconnected, and power breaks therewith.
