Summary of the invention
The vehicle hybrid system of the present invention program, except engine fuel, form primarily of flexible flywheel and monopolar D. C electromagnetic driven machine (HET--HomopolarElectromagneticTransmission), flywheel is as energy carrier, HET in order to stepless change bending moment transferring energy, and is the control axis of manipulation energy flow direction and size.
Contrast existing flywheel hybrid power system, the present invention program mainly has unique distinction in the following areas, and in performance or functionally have significantly progress:
(1) energy transferring of vehicle and recover kinetic energy abrupt deceleration vehicle is driven to adopt HET, the energy transferring that engine fuel fills energy to flywheel adopts HET, outside filling at a slow speed the miniwatt of flywheel can adopt external communication electric rectification to load through the HET rotor coaxial with flywheel, outside can adopt mechanical direct connection loading regime to high-power the filling fast of flywheel, and this is carried in, and filling to stand uses special HET and constant speed synchronous motor; The efficiency of HET transferring energy is very high, can design and reach 96% ~ 98%;

Below technical scheme of the present invention and principle are described in detail.
A kind of engine fuel and flywheel hybrid power system that can be used for the vehicles such as car, passenger vehicle, lorry, comprise: a combustion fuel exports the driving engine of shaft work, one or two accumulated energy flywheel device, the transmission system of connecting engine, flywheel gear and main reducing gear of drive axle, and their control system etc., wherein the nucleus equipment of transmission system is monopolar D. C electromagnetic driven machine (HET).
Accumulated energy flywheel device is the vertical shaft type flexible flywheel device being arranged in vehicle chassis, can adopt one or two flywheel gear.Single flywheel scheme is relatively simple, can select under the condition less at flywheel energy storage capacity, gyro torque is little.Free wheels scheme relative complex, can offset gyro torque, can select under the condition pursuing high stability, high stored energy capacitance.
The specification of two flywheels of free wheels scheme is identical, is only that rotation direction is contrary.Moment direction when a pair flywheel that rotation direction is contrary produces gyro torque is also contrary, and gyro torque when these two Speed of Reaction Wheels are identical can cancel each other completely, is namely zero to the effect entirety of vehicle, only shows as a pair gyro torque and act on vehicle chassis.
Vertical shaft type flywheel has four remarkable advantages, one is be conducive to adopting the bearing assembled scheme optimized, two is be conducive to adopting wheel body flexible connecting structure, three is be conducive to the optimum layout of major diameter flywheel in vehicle, four is be conducive to reducing during vehicle travels the chance and the size that produce flywheel gyro torque, thus reduces gyro torque to the impact load of flywheel structure, bearing and vehicle chassis.
The size of flywheel gyro torque equals the product of following parameters: the sine value sin θ of Rotary Inertia of Flywheel J, flywheel spin velocity ω, vehicle movement cireular frequency Ω, ω vector and Ω vector angle θ.The direction of flywheel gyro torque vector equals ω vector and the long-pending direction of Ω vector multiplication cross, simultaneously perpendicular to ω direction vector and Ω direction vector.Vehicle movement cireular frequency Ω direction vector has three kinds of principal directions: one is vertical shaft direction, corresponding right-left turn vehicle motoring condition, and occur frequent, time length is longer, and magnitude of angular velocity is larger; Two is X directions, corresponding vehicle generation pitch rotation state, such as, in the switching section of uphill/downhill, and when crossing convex closure or pit; Three is y directions, and rollover rotary state occurs for corresponding vehicle, and such as, when turnover rolls slope road, and road conditions are jolted when causing vehicle side to turn.Vertical shaft type flywheel does not produce gyro torque when right-left turn vehicle travels.
Each vertical shaft type flexible flywheel device comprises the wheel body of rotation, a rotating shaft (51), bearing in rotating shaft, vacuum vessel housing (52), shaft centerline is perpendicular to ground, wheel body is many bodies axially symmetric structure, wheel body contains one or more quality bulk (53) and at least one supporting mass (54), these structures are disposed in order successively with the little loop type of big ring sleeve, quality bulk is positioned at outmost turns and time outer ring of rotation, supporting mass is positioned at the inner ring of quality bulk, the fiber-reinforced polymer that quality bulk is wound around by circumference is formed, adopt the flexible zona (55 of two groups of axisymmetric shape, 58) adjacent inner ring and outer ring structure body is connected, a ventricumbent end face of outer ring structure body is placed on a supine end face of inner ring structure body, two end faces are load-bearing end face pair (56), a supine end face of outer ring structure body is placed in the below of a ventricumbent end face of inner ring structure body, two end faces are the end face pair (57 limiting upwards displacement, 64), this end face pair is designed to together with central combination with load-bearing end face pair, form boss and recessinterengaging means.
For the fiber-reinforced polymer that quality bulk (53) is Wrapping formed, its fiber is unidirectional continuous fiber, the optional carbon fiber of kinds of fibers, aramid fiber, glass fibre etc., the optional high-strength glass fibre of glass fibre and E glass fibre etc., adopt Wrapping formed roving; Its poly-mer optional heat thermosetting resin and thermoplastic base resin, the optional epoxy resin of thermosetting resin, unsaturated polyester resin, phenol resin, bimaleimide resin, polyimide resin, cyanate ester resin etc.Carbon fiber reinforced polymer is compared with glass fiber reinforced polymer, and its advantage is: circumference (hoop) tensile modulus of elasticity is higher, and during rotation, distortion is less; The density of composite material is less, and strength-to-density ratio is higher, and the energy storage density of unit weight is higher; Its shortcoming is: carbon fiber is expensive, and cost of product is very high; Because density is less, and the advantage of intensity and not obvious or only maintain an equal level (relative high-strength fiber glass), the energy storage density of its unit volume is lower.Therefore, adopt glass fiber reinforced polymer to have more comprehensive advantage, suitable economy of large scale application, all the more so after distortion and the large Resolving probiems of creep compliance.
Quality bulk (53) can be single, two, three etc., weigh choice from respective merits and faults and select.Select the advantage of single quality bulk to be take full advantage of high linear speed region, higher unit weight energy storage density can be obtained, but its endoporus takes up space and can not effectively utilize, cause the energy storage density of the unit volume calculated with whole equipment volume on the low side.Select the advantage of two quality bulk to be suitably make use of available space, and the quality bulk being positioned at inner ring can adopt intensity lower but the fiber that price is more honest and cleaner and resin, its shortcoming is that unit weight energy storage density is less than single quality bulk scheme.
Supporting mass (54) Main Function of wheel body is connected between quality bulk with rotating shaft, and supporting mass number depends on connection radial dimension ratio and supporting mass material kind.The fiber-reinforced polymer that the optional circumference of supporting mass material is wound around, also selective metal material, the former must adopt in the inefficient higher line velocity location of Strength of Metallic Materials.The same reason very low because of radial strength, fiber-reinforced polymer supporting mass also often has the situation of many bodies.Because linear velocity is lower than quality bulk, supporting mass fiber-reinforced polymer can select intensity lower but the fiber that price is more honest and cleaner and resin.The supporting mass of innermost circle should select metallic material, is beneficial to the connection with rotating shaft.The optional steel of supporting mass metallic material, aluminum alloy, titanium alloy etc., aluminum alloy and titanium alloy have higher strength-to-density ratio, and the external diameter of made supporting mass is comparatively large, can reduce the quantity of fiber-reinforced polymer supporting mass; Aluminum alloy also has that price is lower, the feature of lighter in weight; Steel supporting mass can double as the rotating disc of permanent magnetic attraction cod, at this moment adopt No. 45 or 40Cr steel better.
Because Wrapping formed fiber-reinforced polymer is easily pulverized as flocculence fragment when High Rotation Speed failure damage, there is good safety, therefore, the more outer circle in position, wheel body that energy storage is larger adopts fiber-reinforced polymer to have security advantages clearly.
Load-bearing end face pair (56) and restriction to the axial location of the end face pair (57,64) of top offset being good near the center of gravity of load.Two opposing end surfaces of end face pair (56,57,64) leave allowance in radial height, the radial displacement dislocation produced during to compensate rotation, make end face pair to maximum speed, remain actv. active area static.Very close to each other between two opposing end surfaces of end face pair (57), combine axial location effect with load-bearing end face pair (56), forced limit angles to misalign change, closely participate in the transmission of force and moment; Have gap between two opposing end surfaces of end face pair (64), play the position-limiting action of restriction outer ring structure body to top offset, limit angles misaligns change to a certain extent, sometimes or partly participates in the transmission of force and moment.For increasing the resistance to abrasion of the secondary contact surface of end face; increase effective area of contact; protection fiber-reinforced plastic surface; and the object such as reliability and durability and absorbing; two opposing end surface materials of end face pair (56,57,64) can adopt rubber elastic material; as adopted poly-urethane rubber, rubber end face thin plate (65) or rubber end face chunk (66) are glued together with matrix.Rubber end face chunk (66) has larger elasticity and distortion suitability, but its centrifugal load is comparatively large, should be arranged on the matrix of outer ring, adopts matrix inner hole surface carrying centrifugal load.Because the load of load-bearing end face pair (56) is larger, matrix appended by selection and Wheel structure main body are structure as a whole, guaranteed load bang path has sufficient margin of strength, and non-bearing end face pair (57,64) one end matrix adopts accessory structure, this accessory can be connected and fixed with adhesion agent and main matrix, and fitment material adopts the material same with main matrix phase.
Flexible zona (55,58) the two groups of designs connecting adjacent inner coil and outer ring structure body are comparatively applicable to the moveable type occasions such as vehicle, and better with the axial span of two groups.Often organize flexible zona to be made up of monolithic or more sheets of flexible zona, quantity depends on the consideration of the factors such as strength and stiffness.The flexible zona of every sheet all with inner ring and outer ring matrix gluing, existing directly gluing with main matrix, also have with accessory structure gluing, accessory structure is gluing with main matrix again, the material that fitment material adopts and main matrix phase is same.Installing condition can be adopted not prebend the flexible zona (55) of distortion, and be made up of two ends root and middle body portion, the root of band cap head is gluing with matrix, and body portion thickness radially convergent designs, to reduce maximum stress.Also installing condition can be adopted to have prebend the flexible zona (58) of distortion, zona part free state is in a pre-installation equal thickness flat washer shape, during installation, imposed deformation is to a side bending, distance rotating shaft zona degree of crook is remotely comparatively large, substantially stretching to zona during maximum speed in rotation.Flexible zona (55,58) material is elastomeric material, comprises elastomeric material, as poly-urethane rubber.Flexible zona (58) also can adopt the composite material of elastomeric material and radial fortifying fibre, and the fiber arranged along radial direction concentrates on center membrane face, significantly improves zona radial strength, does not affect the bending of film simultaneously, does not also reduce the elasticity of circumference.Carry out circumferential tension when flexible zona (58) is installed, increase zona internal orifice dimension to fit dimension, keep zona external diameter constant.For the flexible zona of the two group (58) between mass, optional setoff installation (the Figure 20 of the flexible zona of certain axial distance is had with location end face pair, enlarged drawing IV), Offset compensates the axial shrinkage difference of outer ring relative inner ring when rotating, and is in radial straight configuration in the hope of the zona when maximum speed.For the flexible zona of the two group (55) between mass, there is the optional inclined design of flexible zona of certain axial distance with location end face pair, be in radial straight configuration in the hope of the zona when maximum speed.
" flexibility " connection mode of the present invention program, the overbalance of each block can be compensated, significantly can reduce the requirement to dynamic balance calibration, automatically Large travel range distortion when operating and creep deformation can be adapted to, significantly can reduce the unbalance dynamic force and moment of rotary wheel countershaft effect, final reduction is to the disturbance force of bearing and vibration.
Can directly be connected between flywheel rotating shaft (51) and the supporting mass (54) of innermost circle, as circular conical surface interference connects; Also step disk (62) can be installed between, the central bore of step disk is connected with rotating shaft, and as circular conical surface interference connects, the dish body of step disk is positioned at below the supporting mass of innermost circle, therebetween install elastomeric material ring (63), the latter to be gluingly connected with the two.The object material be connected with rotating shaft interference should be taken as with rotating shaft of the same type, as being taken as steel, to make the parameter difference such as modulus of elasticity, linear expansion coefficient of the two little, being beneficial to and reducing stress in installation with during use and ensure that interference is connected.Be generally steel with the direct coupled innermost circle supporting mass of rotating shaft, its external diameter is less, and its rotor inertia is general very little.When innermost circle supporting mass aluminium alloy or titanium alloy material, its external diameter is larger, its rotor inertia is also larger, comparatively need to flexibly connect, simultaneously the problem that is connected with steel rotating shaft interference of light alloy also comparatively greatly, therefore, the steel step disk of middle transition and the structure of elastomeric material ring is adopted to be preferred solutions, elastomeric material ring wherein play simultaneously flexibly connect, load-bearing and axial location effect, its material can use elastomeric material, as poly-urethane rubber.
Vacuum vessel housing (52) is designed to the two halves structure of vertical axis subdivision, and circle flange (67) is positioned at the middle part of housing outer round surface, and flange can be positioned at outside of containers or inner side.Inside flange, design is intended to reduce realistic aerodynamic configurations size, screwde on is not established in inner flange limit, rely on the pressure compaction that container vacuum produces, when adopting this design, also set up four sections of ear flanges (74) and screwde on thereof at outside of containers corner place simultaneously, this corner location selects the place not affecting realistic aerodynamic configurations size, such as, do not affect the 45° angle orientation arranging width and length.At whole circle flange, rubber seal is set, also vacuseal grease can be set up in the outside of rubber seal, also can set up flexible metal sealing washer in the inner side of rubber seal, also can set up vacuseal grease in the outside of rubber seal and set up flexible metal sealing washer in inner side.The installation supporting portion of housing utilizes the flange exposed, and this is also the installation supporting portion of whole flywheel gear and connected structure thereof.
As the safety prevention measure increased, at outmost turns quality bulk and can set up the strong protection sleeve of pardon (68) outside it between housing, protection sleeve and housing mutually by supporting, but do not limit sleeve rotating.Protection sleeve can arrange one or more, allows to rotate freely between multiple sleeve, and two sleeves respectively have side strap end portion apron (68).
Vacuum vessel housing (52) can adopt three-layer composite structure (Figure 21, Figure 22), and interlayer is fiber-reinforced plastic, and two outer surface layers are lightweight metal material, and interlayer is connected with outer surface layer is gluing.The optional glass fibre of fortifying fibre, carbon fiber etc., use the materials such as non-unidirectional cloth fabric, Chopped fiber, felt.The optional epoxy resin of resin, unsaturated polyester resin, phenol resin etc.Interlayer can adopt sheet molding compound (SMC) to carry out forming work.The preferred aluminum or aluminum alloy of outer surface layer light-weight metal.The advantage of three-layer composite structure is: damping of vibrations is large, and intensity is high, good toughness, lightweight.
The radial support bearing of flywheel rotating shaft (51) can with two groups of antifriction-bearing boxs, also can with two radial support magnetic suspension bearings.Its axially mounting bearing adopts one group of axially mounting magnetic suspension bearing.

A permanent magnet expulsive force formula axially mounting magnetic suspension bearing has a rolling disc and a stationary disk, rolling disc is positioned at the top of stationary disk, an air gap is had between the sides adjacent end face of two dishes, rolling disc is rotational symmetry magnet structure, or the mixed system of rotational symmetry soft magnetic bodies and rotational symmetry permanent magnet, or rotational symmetry non-magnetizer, the mixed system of rotational symmetry soft magnetic bodies and rotational symmetry permanent magnet three, stationary disk is rotational symmetry magnet structure, or the mixed system of rotational symmetry soft magnetic bodies and rotational symmetry permanent magnet, or rotational symmetry non-magnetizer, the mixed system of rotational symmetry soft magnetic bodies and rotational symmetry permanent magnet three, the magnetic circuit that magnetizes of above-mentioned all permanent magnets is also axially symmetric structure, the magnetic pole that on two dish sides adjacent end faces, same radius place is relative is contrary, magnetic repulsion upwards acts on rolling disc, design the gravity being used for offsetting rotor.
A permanent magnetic attraction formula axially mounting magnetic suspension bearing has a rolling disc (59, 54) and one stationary disk (60, 61), rolling disc is positioned at the below of stationary disk, an air gap is had between the sides adjacent end face of two dishes, rolling disc is rotational symmetry soft magnetic bodies structure, stationary disk is rotational symmetry magnet structure, or the mixed system of rotational symmetry soft magnetic bodies and rotational symmetry permanent magnet, or rotational symmetry non-magnetizer, the mixed system of rotational symmetry soft magnetic bodies and rotational symmetry permanent magnet three, the magnetic circuit that magnetizes of above-mentioned all permanent magnets is also axially symmetric structure, magnetic attraction upwards acts on rolling disc, design the gravity being used for offsetting rotor.
Above-mentioned magneto axially mounting magnetic suspension bearing does not have magnetic hysteresis and eddy loss.Permanent magnetic attraction formula compares with permanent magnet expulsive force formula, has two large advantages: one is that rolling disc does not need to install permanent magnet, and the intensity of permanent magnet is very low; Two is that the magnetic flux density of magnetic end face can organization design comparatively large, obtains larger bearing suction with less bearing outside diameter size.
Two groups of antifriction-bearing boxs of flywheel rotating shaft (51) radial support, one group of antifriction-bearing box bears Radial load, and another group antifriction-bearing box bears Radial load and bi-directional axial load, and is axial location end.Often organize antifriction-bearing box to be made up of an antifriction-bearing box or multiple antifriction-bearing box, to meet the requirement of load and direction.Axial location end is generally positioned at upper end.When flywheel gyro torque is larger, two groups of radial protection antifriction-bearing boxs can be set up, to bear overload diametral load in short-term.

During vehicle immobilization to flywheel fill can driving engine prioritizing selection use maximal efficiency operating mode, when needing the shorter load time, can the operating mode of choice for use relatively high power, until maximal power condition.Before the driving engine loading condition arriving above-mentioned selection, what have one to start from idling operation rises operating mode transient process, before loading, the rotating speed of flywheel is not less than index rotating speed, namely when stand under load power capability is not less than driving engine loading condition power, rising operating mode transient process can be very fast, when the rotating speed of flywheel before loading is lower than index rotating speed, rise operating mode transient process just with the course synchronization of flywheel raising speed to index rotating speed, at this moment the larger direct torque to flywheel can be selected, to accelerate transient process, such as, when flywheel is from zero rotating speed raising speed, adopt permanent maximum torque control, at flywheel from non-zero, comparatively during slow speed of revolution raising speed, leading portion adopts the torque fast lifting curve controlled from zero torque, back segment adopts permanent maximum torque control.
When here is the vehicle immobilization of several typical case, driving engine fills the special case scheme of energy to flywheel:
