4. simple in structure, easy to maintenance
Rotor adopts permanent magnet (neodymium iron boron), and no power does not have electric wire and silicon steel sheet not to have brush (commutator), can not produce wearing and tearing, therefore needs repairing hardly.
5. can make difunctional output and tandem axles
Because the rotor no power does not wind the line, rotor can be made hollow, these space two ends can the various clutches of design arrangement or the centre can arrange differential mechanism, easily obtain difunctional output and through differential mechanism drive axle.
6. reduce parts, save the space
Compare with the conventional electric fork truck and to have reduced that a motor, a cover are automatically controlled, the storage battery volume reduces 1/3rd, volume significantly reduces, and is easy to the layout of electri forklift and other electric industry vehicles.
7. provide free the infinitely variable speeds that hoists
For the infinitely variable speeds control that hoists is provided; General electric control gear will 12,000 yuan of one cover; Because this patent moves, hoists and only use a motor; So, improved the operating efficiency of fork truck and driver's comfortableness greatly as long as can realize the stepless speed regulation that hoists with original traveling stepless speed regulation.
8. market potential is big
China's electri forklift annual production is 50,000, and tourist coach, rising car, sweeper are also equally matched, and the overall market amount of 100,000 of year pins is arranged approximately, and global electri forklift is about 510,000; Other industry electric motor cars are about 300,000, and by 20,000 yuan of sale of every cover, domestic overall market amount is 2,000,000,000 yuan/year; Export price is better, and by 5000 dollars in every cover, sales volume is about 4,000,000,000 dollars/year; By 20% of the market share, the annual output value is about 800,000,000 dollars, and profit is about 1,000,000,000 yuan of RMB.
The diesel fork lift truck engineering machinery all has attached operating mechanism; All available dual function system is especially under the moving situation of combustion power fax, (as adopting the internal combustion mixed dynamical device;) can significantly raise the efficiency; Reduce oil consumption, the market potential of this respect will get surprising greatly, several times even several battery fork lift truck that decuples.
More than a disclosed specific embodiment that is merely the application, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection range.
