Abstract

The utility model relates to a motor/electric generator integrated device mounted on wheels of an electromotor, which comprises a rotor and a stator, wherein, magnets of both polarities are arranged alternately to form the rotor, and the stator is wrapped with alternating current loops. A frame of the rotor is a vehicle wheel rim and the magnets. The magnets are inlaid on the inner surface of the vehicle wheel rim. The frame of the stator wrapped with the loops is fixedly sheathed at an intermediate axle of the wheels, and is positioned on the intermediate section at an inner ring of the vehicle wheel rim. The utility model has the advantage that a driving means of a traditional electric vehicle is changed. Each wheel itself is changed into the motor. The driving efficiency is raised substantially. Each wheel is a double duty device of an electric machine and the electric generator, and therefore, the efficiency of regenerate electrical energies is raised under the condition that the wheels still move inertially after power cut.

Description

Be contained in the driving motor of electric vehicle/generator all-in-one on the wheel

The utility model relates to a kind of device that collects drive motors and generator one, particularly is contained in the driving motor of electric vehicle/generator all-in-one on the wheel.

The type of drive of present existing solar electric vehicle and electric motor car generally is divided into two kinds: preposition motor front-wheel drive and preposition motor rear wheel drive.Front-wheel drive belongs to " drawing " formula and drives, and this is than " promotion " formula type of drive of rear wheel drive, and very effort can seem when car body is climbed; And preposition motor-driven trailing wheel owing on drive system, consume certain energy, so that drive motors work doing efficiency be subjected to very big influence.In a word, the type of drive of above-mentioned two kinds of single motors all can not make the torque of motor and mechanical property reach ideal effect.

The utility model purpose is: overcome the deficiency of prior art, provide a kind of and change the conventional ADS driving mode, be intended to improve drive and energy regeneration efficient be contained in driving motor of electric vehicle/generator all-in-one on the wheel.

The utility model is achieved in that the driving motor of electric vehicle/generator all-in-one that is contained on the wheel, comprise the rotor that constitutes alternately by two kinds of polarized magnets and stator around alternating current coil, it is characterized in that: the skeleton of rotor is that Wheel, magnet are embedded on the Wheel inner wall surface, is wound with on the fixedly sleeved stage casing that is arranged in the Wheel ring at the wheel jack shaft of the stator skeleton of coil.Have spline on the interlude surface of wheel jack shaft, also have the spline of corresponding cooperation on the stator skeleton inner surface.

On the such scheme basis, the utility model also is furnished with a fixing steel disk, and its bottom center leaves bearing saddle bore, has bolt hole with skidding dish Joint all around, has the bolt hole with the inner edge of Wheel Joint on its lateral column face.Be provided with the inside and outside midship shaft bearing that all has spline on the outer surface, fixedly the central shaft bearing hole of steel disk all has the matching spline groove of corresponding inside and outside bearing respectively with central shaft bearing hole on the Wheel outer face.

The utility model advantage is:

1, because the utility model comes down to the electric bicycle wheel itself is become motor, therefore in the driving process, just omitted the energy consumption on the drive system fully.And on forward and backward all wheel, all adopt this structure, so just traditional electric motor car " can be drawn " formula or " promotion " formula type of drive and change into the automatically also high efficiency type of drive of " promotion " of trailing wheel " drawing " time of front-wheel fully.

2, the utility model is to drive and power generation dual-purpose device, and as motor, drive wheels is rotated during energising; Car is after braking or sliding time outage, and wheel becomes generator again and produces electric energy and feed back to energy storage battery according to being used in the row rotary course it, and because each wheel all is a generator, so this electric energy regeneration efficiency is higher.

Fig. 1 is a half sectional view of the present utility model.

Fig. 2 is a cutaway view of the present utility model.

Fig. 3 is a decomposition assembling figure of the present utility model.

Below in conjunction with drawings and Examples the utility model is further specified.

Shown in Fig. 1～3: 1, vehicle tyre, 2, Wheel, 3, stator coil skeleton, 4, stator coil.5, the fastening bolt of jack shaft and Wheel, 6, the external bearings baffle plate, 7, alnico magnets, 8, fixedly steel disk and Wheel fastening bolt, 9, skidding dish and steel disk connecting bolt, 10, power supply terminal, 11, the brake actuator oil pipe, 12, the disk type brake brake(-holder) block, 13, the spline jack shaft, 14, skidding pincers assembly, 15, the skidding dish is connected base with fixing steel disk, 16, fixing steel disk, 17, portion's bearing in the Wheel, 18, the Wheel external bearings, 19, stator, 20, stator mesopore internal splines groove 21, wheel and fixing steel disk connecting bolt hole, 22, Wheel spline slot type bearing pedestal, 23, fixing spray of molten steel keyway formula bearing pedestal.

Referring to Fig. 3, stator coil winding 19 first encapsulations are to jack shaft 13, and the inner spline groove 20 of stator matches with spline on the jack shaft stage casing; The external bearings 18 that has spline is sleeved on the left side of jack shaft 13, reinstalls in the bearing pedestal 22 that Wheel 2 has inner spline groove; In portion's bearing 17 cover install on jack shaft 13 right sides and 23 li of the inner spline groove bearing pedestals of the fixing steel disk 16 of packing into; The base 15 of skidding dish 12 fixes as one by bolt 9 mutually with fixing steel disk 16; By bolt 8, pass the hole 21 on (right side) end edge in hole on steel disk 16 sidewalls and the Wheel 2, the two is fastened as one; External bearings baffle plate 6 is installed on the left side spindle nose of jack shaft 13 at last, tighten hold-down nut 5 again and get final product.Inlaying polarity alnico magnets 7 alternately on the inner wall surface, after assembling is finished, stator coil winding 19 is positioned among the encirclement of magnet 7, its both sides respectively by the outer end panel of Wheel 2 and fixedly the bottom surface of steel disk 16 keeping off, whole stator 19 is closed in the interior ring hollow of Wheel 2, and the power supply terminal 10 of coil is the centre bore output wheel outer (with reference to Fig. 1,2) by jack shaft 13.

In the said structure, the spline between the mesopore 20 of jack shaft 13 and stator 19 cooperates, and is in order to guarantee that stator 19 is all the time with respect to jack shaft 13 splines; Fixedly steel disk 16 both had been used for stator 19 is enclosed in the Wheel 2, again as the connector between Wheel 2 and the brake block 12; They cooperate inside and outside two bearings 17,18 with bearing pedestal 23, the spline between the bearing pedestal 22 on the Wheel on the steel disk respectively, are in order to guarantee that jack shaft 13 does not change relatively when the wheel.

The utility model operation principle is: when power connection, storage battery in the electric motor car is the binding post 10 conveying alternating currents of each wheel by inversion system, behind the stator coil winding 19 logical upward alternating currents, the magnet 7 that excitation immediately is embedded on Wheel 2 inwalls produces alternating magnetic field, so under magneticaction, Wheel 2 just begins rotation, drives simultaneously with it that the fixedly steel disk 16 and the skidding dish 12 of one rotates together, and whole like this electric motor car has just moved; When car is in outage sliding state or power-off brake braking state following time, as long as wheel still be in inertia rotate, when not stopping as yet, the electric motor structure of installing in the wheel promptly changes generator work into: with the magnet of wheel rotation, make to produce AC electromotive force in the fixed stator coil, this regenerative electric energy becomes direct current by a rectifier and feeds back in the storage battery.
