Dress is all magneto, and fuel vehicle is different from occupation mode, and it does not have idling device, only power supply and zero power supply
Point, after being powered off in vehicle traveling, because the height of front and rear rotating speed changes, the square groove advance automatic clutch of water chestnut key half, which plays, to be made
With having cut off the resistance that the design structure of magneto and decelerator is brought, made vehicle overlength distance in the presence of inertia force
Slide.Under flat road conditions, the groove advance automatic clutch of user water chestnut key half being continuously interrupted can save energy 20%-30%, quick
Power-off and the method powered at a slow speed in use, make it is front and rear both rotating speed it is essentially identical when, heavy-current discharge can be avoided to battery
The loss for the short life brought.
（5）Five assembly needle bearings are provided among deceleration body in rear portion of the present invention, its design form is by five
Combination of monomers together, is to maintain combining for Multifunctional main reduction gearing and rotation type differential cage, but relatively independent, at it
Mutual cooperation under realize energy-conservation, this has had pioneering in world car industry history.
（6）The right side of deceleration body in rear portion of the present invention is provided with the synchronous reverse clutch of multifunctional safe advance, new energy vapour
Car should adapt to, in national each regional and various road conditions, such as at the long slope in lower abrupt slope, use multifunctional safe as fuel vehicle
Advance synchronous reverse clutch, coordinates the reluctance force of magneto and subsidy brake work(that the slow-speed of revolution and reducing gear are converted into again
Can, regulation speed, prevent that now the groove advance automatic clutch of water chestnut key half has lost function to driving and multifunctional safe advances synchronously
Reverse clutch rotates in same direction, and when needing reversing, changing the rotation direction of motor can move backward.
（7）The center of deceleration body in rear portion of the present invention is provided with rotation type differential cage, and it is a multiple combination of monomers
Separate component, its semiaxis with vehicle coordinates, after the vehicle power-off in car traveling, the stalling of Multifunctional main reduction gearing, and square water chestnut key half
Groove advance automatic clutch automatic clutch, five assembly needle bearings play function and start rotation, make car just under steam
Slided forward with the inertia force still having, running resistance of the prior art is thoroughly excluded.
