The specific embodiment

The invention will be further described below in conjunction with drawings and Examples.

A kind of novel generating energy regenerative mechanism 3 is integrated in the wheel, obtains a kind of energy regenerative tire; This energy regenerative tire comprises: tire 1, wheel rim 2, generating energy regenerative mechanism 3, nut 4 and bolt 5.

Generating energy regenerative mechanism 3 comprises mover iron core 31, three phase windings 32, adapter plate 33, stator pendulum 34 and ball 35; Mover iron core 31 is embedded with three phase windings 32, and has four axial unthreaded holes along circumferentially evenly offering teeth groove in the teeth groove, in order to fixing with wheel rim 2; Adapter plate 33 is the ring-shaped cylinder structure, have four unthreaded holes vertically, the aperture is identical with axial unthreaded hole pore size on the mover iron core 31, four unthreaded holes are distributed in the circumference of adapter plate 33, mover iron core 31, adapter plate 33 are fixed with wheel rim 2 by nut 4 and bolt 5, in the vehicle operating process, mover iron core 31, adapter plate 33 rotate with wheel; Adapter plate 33 has annular T type groove along circumference, is used for placing stator pendulum 34; Four raceways are arranged in the T type groove, be respectively raceway A, raceway B, raceway C and raceway D, filled ball 35 along circumference in the raceway, main purpose is the friction that reduces between stator pendulum 34 and the adapter plate 33.

Stator pendulum 34 is that T-steel 341 and the arc-shaped permanent magnet 342 by arc is welded arc-shaped permanent magnet 342 radial magnetizings, N, S utmost point alternative arrangement; The T-steel 341 of arc is enclosed within the T type groove of adapter plate 33 by ball 35 skies; Stator pendulum 34, does not rotate with mover iron core 31 in the vehicle movement process synchronously owing to be subjected to the effect of self gravitation.

Below in conjunction with accompanying drawing specific implementation process of the present invention is described further.

In the vehicle movement process, mover iron core 31, adapter plate 33 are captiveed joint by bolt 5 with wheel rim 2, and mover iron core 31 and adapter plate 33 can rotate synchronously with wheel; The arc T-steel 341 of stator pendulum 34 is enclosed within the T type groove of adapter plate 33 by ball 35 skies, owing to be subjected to the effect of self gravitation, it is different with adapter plate 33 that stator is put 34 rotating speeds, can regard stator pendulum 34 this moment as and maintain static, and adapter plate 33 rotates along stator pendulum 34; Because adapter plate 33 is identical with mover iron core 31 rotating speeds, then stator pendulum 34 produces relative motion with mover iron core 31, the magnetic line of force of the arc-shaped permanent magnet 342 of radial magnetizing induces the three-phase alternating current electro-motive force in three phase windings, the 32 cutting stators pendulum 34 in the mover iron core 31 in three phase windings 32.

In the new-energy automobile, storage battery is crucial, and engine starting and lighting need storage battery that powerful electric power is provided, thereby must guarantee the accumulator electric-quantity abundance.If accumulator electric-quantity deficiency, the load performance that can ignore driving engine, this moment is with the load of storage battery as driving engine, making a part of kinetic wheel be converted into electric energy by generating energy regenerative mechanism 3 charges a battery, by connecting the energy regenerative loop, make generating energy regenerative mechanism 3 be operated in loading condition, induce counter potential in three phase windings 32, because energy regenerative circuit closed, a part of kinetic energy of wheel is converted into electric energy, behind electric energy process Three-Phase PWM Rectifier and the DC-DC boost conversion circuit, to the composite energy storage system charging of being formed by storage battery and super capacitor on the new-energy automobile, kinetic wheel is converted into electrical power storage, uses during for automobile starting or acceleration; If accumulator electric-quantity is full of, then can break the energy regenerative loop in the vehicle normal course of operation, this moment, the energy regenerative mechanism 3 that generates electricity was operated in light condition, though induce three phase electromotive force in three phase windings 32, but because the energy regenerative loop disconnects, there is not electric current in three phase windings 32, do not have kinetic energy to be converted into electric energy, alleviated the load of driving engine; When accumulator electric-quantity is not enough, can reclose the energy regenerative loop, the energy regenerative of then generating electricity mechanism 3 is converted into the electric energy accumulators with a part of wheel rotation function again and charges, and so moves in circles.

In the car brakeing process, if braking energy is not reclaimed, then this part energy can be converted into thermal dissipation in air, at this moment, can connect the energy regenerative loop, make generating energy regenerative mechanism 3 be operated in loading condition, stator pendulum 34 induces alternating current with mover iron core 31 owing to relative motion in three phase windings 32 of mover iron core 31, alternating current process Three-Phase PWM Rectifier and DC-DC boost conversion circuit are converted into direct current (DC) and charge a battery, braking energy is converted into electrical power storage, reaches the purpose that braking energy is reclaimed.

For this energy regenerative tire, can control whether reclaim the energy that wheel rotates generation by being switched on or switched off the energy regenerative loop, easy to operate, alerting ability is strong, has improved life-span and the work efficiency of storage battery; Meanwhile, this generating energy regenerative mechanism 3 itself is because the particularity of mechanism, can be transplanted to carry out energy in other rotation type games construction machinery and equipments and reclaim, and portability is stronger, thereby very strong practicality and applicability are arranged.
