The utility model content
The purpose of this utility model just is to provide a kind of electric car travel increasing device that can effectively improve the electric motor car course continuation mileage.
The purpose of this utility model is to realize by such technical scheme, a kind of electric car travel increasing device, described distance increasing unit comprises the magnetic magnet steel external rotor be arranged on the engine power shaft, be provided with corresponding with magnetic magnet steel external rotor in described magnetic magnet steel external rotor inner chamber and be arranged on the coil on engine housing, being provided with the cooling fan be connected with magnetic magnet steel external rotor outer face in the outer face of described magnetic magnet steel external rotor.
For fixing and location, described cooling fan is connected with the outer face of magnetic magnet steel external rotor by pressing plate.
For the ease of dismounting and maintenance, between described magnetic magnet steel external rotor and power shaft, by removable, be fixedly connected with, be provided with screw thread in the termination of described power shaft, described magnetic magnet steel external rotor is inserted in the power shaft termination and fixes by nut.
In order to reach the purpose of simultaneous ignition, be provided with trigger on described engine housing, be provided with the trigger boss matched with trigger on the outer wall of described magnetic magnet steel external rotor, described trigger is connected with the high voltage package with direct-current ignitor on being arranged on the engine housing outer wall.
In order to dispel the heat, be outside equipped with the fan guard with air inlet be connected with engine housing at described cooling fan.
In order to improve security performance, in the upper of described engine housing and be positioned at the engine output shaft end and be provided with seal cover.
Owing to having adopted technique scheme, the utlity model has that structural design is ingenious, installing/dismounting is easy, be convenient to the advantage of maintenance, compact conformation, adopt it not only to dwindle the volume of complete machine, reduce weight, and can make distance travelled be increased.
The accompanying drawing explanation
