The car body permanent magnet produces mutual repulsive force with the track permanent magnet because of same polarity is relative, thereby car suspended, is directed to, and because lift force, the guidance force of being produced all are repulsion, so suspend, guiding is self-stabilization and adaptive.
The principle of propeller of car: electro-magnetism discloses, electrical conductor in the magnetic field is subjected to application force, the size of application force is calculated by relational expression F=BIL, wherein B represents magnetic induction density, and I represents the intensity of current in the conductor, and L represents electric conductor the overall length dimension in magnetic field vertical with the magnetic line of force in magnetic field, to wound coil, L equals coil turn and every circle average perimeter is long-pending, and for the combination electric conductor, L equals the circumferential lengths of described conducting ring jaggy; The direction of application force is judged according to left hand rule, promptly stretch out left hand, make thumb four refer to vertically in same palm plane, allow the N utmost point of the palm of the hand over against magnetic field with all the other, four sensings are consistent with the direction of current in the electric conductor, and at this moment thumb just indicates the force direction that is subjected to of conductor.In the utility model, show as Fig. 2, if the direct current (DC) that feeds to left coil is clockwise, simultaneously, the onesize direct current (DC) of feeding for right coil is an anti-clockwise, determine easily with left hand rule, the force direction that every limit of two coils is subjected to all leaves the beholder and goes, and promptly vertically points in the paper, so car advances by this direction, change the direction of current in two coils (or two combination electric conductors) simultaneously, the sense of motion of car just changes.Track of the present utility model and car, in case achievements, B, L are relative definite value just, obviously, the size that only changes I just can make car along with the variation of I is quickened or deceleration, and the size of change I is the technology that realizes easily.
When car moves, because the electromagnetic induction between coil or combination electric conductor and the track permanent magnet, in coil or combination electric conductor, can produce more stable induced current, its direction and the current opposite in direction of importing from power supply, the intensity of current of intensity ratio input is little, suppressed by supply current, thereby in fact do not have the electric current of inducting in coil or the combination electric conductor.When moving, car cuts off the electricity supply, the car inertia motion, the magnetic field of the induced current in the coil and track permanent magnetic field mutual action, to hinder the motion of car, as long as thereby reduce intensity of current in coil or the combination electric conductor, not only reduced power, realization is slowed down naturally, and produce braking force simultaneously, realize brake deceleration, so coil or combination conduction physical efficiency assist brake.Thus, power supply can be designed and produced and to become to have two-way adjustable function---coil or the power supply of combination electric conductor can be given, the induction electric energy in the brake deceleration process can be from coil or combination electric conductor, reclaimed again.
By the above principle,, consider the guidance force requirement simultaneously according to the full weight (containing load-carrying) and the speed of a motor vehicle requirement of car, the configuration power supply, design coil or combination electric conductor, design track, just can realize that car stably suspends, leads and advances, the operation of described car is a self-stabilization and adaptive.
