Description

The moving iron core of electric automobile, electro-tricycle automatic gear-box

Technical field

The utility model relates to electric automobiles, particularly relates to the moving iron core that is applied to electric automobile, electro-tricycle automatic gear-box.

Background technology

Electric control mechanical type automatic speed variator (Automated mechanicalTransmission, be called for short AMT), the feature of AMT speed change system is known in the art with operating in, for example AMT has advantages of that driving is comfortable, reduces driver's fatigue, the electric motor car that automatic transmission is housed can be according to pavement behavior automatic speed-changing and torque-converting, driver can watch absorbedly road traffic attentively and can not do in a rushly because of gearshift, and AMT fluid drive can make driver realize fluid drive under the situation of not cutting off power.

Electric motor car green, environmental protection, run cost are low, liked by user, from only 20,000 people of calendar year 2001 China's electric power user, are greater than 100,015,000 short being developed so far in about ten years, and market prospects are very vast as can be seen here; No matter be consumption or production, China occupies first of the world, international energy gentle temperature rise in short supply thereupon, electric-powered not only unit mileage usage charges are low, and meet low-carbon emission reduction requirement, and be the major project of the 863 and the 12 five-year plan of China, annual requirement constantly promotes.

Known electric vehicle motor, there are hub-type, gear graduation motor, hub-type is that one to one transmission, gear graduation motor are direct driven by motor gears, this transmission mode exists rotating speed and the immutable defect of moment of torsion, with existing motor assembling electric motor car, cannot realize the climbing demand of many times of increases of moment of torsion.As electric power, be in operation compared with fuel combustion vehicle, its energy is to be compensated; so system effectiveness becomes electrodynamic key index; no matter be fuel oil or electronic, it has peak efficiency usage space, and designer is conventionally using peak efficiency section as nominal operation efficiency; only have in this state; it is the most energy-conservation, therefore, in use adopts mechanical changeover can change electric efficiency curve; not only be satisfied with operation demand, and effectively protected storage battery.Electrodynamic AMT technology, the direct effect that it plays allows fool drive arbitrarily to shift gears exactly, no matter very fast or climbing, after switching gearratio, change motor operation curve, system is all moved in high efficiency section, and simple in structure, manufacturing cost is lower, automaticity is higher, it can be made and being run slowly by speed changer according to motor vehicle speed, increase output torque.

For meeting the concrete enforcement that application number is 2014101425545 small-power AMT automatic speed regulating differential motor patented technology, present patent application has proposed a kind of new moving fabrication of iron core scheme.

Summary of the invention

For solving the total structure of the small-power AMT automatic speed regulating differential motor patented technology that application number is 2014101425545, the inventor recognize a kind of by electromagnetically operated valve as power, promoting expansion link by moving iron core moves up and down, can make motor vehicle in the time advancing operation, adopt unidirectional drive, intersect self-locking in when operation of reversing gear by expansion link and driving-disc limit shaft and realize bi-directional drive, direct effect of the present utility model be vehicle under steam when off-position drive system depart from speed changer reducing gear and motor magnetic resistance, strengthen coasting ability, extend mileages of continuation.

The moving iron core technical scheme of the utility model electric automobile, electro-tricycle automatic gear-box is, moving iron core is that carbon steel is made, it is characterized in that moving iron core is placed in casing tube internal hole, spacing during to the reset of moving iron core by blind nut, in the time that electromagnetically operated valve often leaves, moving iron core is to the adhesive of static iron core direction, aligns with static iron core upper surface in moving iron core lower surface, when electromagnetically operated valve is normally closed, moving iron core resets under the thrust of expansion link.

The moving iron core of the utility model electric automobile, electronic three wheel automatic gear-box, is the execution unit of solenoid control expansion link, and moving iron core is accepted the order of electromagnetically operated valve all the time, in the time that electromagnetically operated valve often leaves, moving iron core is to the adhesive of static iron core direction, and in the time that electromagnetically operated valve is normally closed, moving iron core resets.

In a kind of form, moving iron core lower end is shaped with endoporus, the little axle close fit of endoporus and expansion link, the little axle of expansion link is placed in moving iron core endoporus all the time, in the time that electromagnetically operated valve often leaves, moving iron core, to the adhesive of static iron core direction, promotes the little axle of expansion link and moves down, and that realizes expansion link and driving-disc limit shaft circumferentially intersects self-locking.

In a kind of form, moving iron core below is shaped with moving core center axle, moving core center axle is placed in static iron core endoporus, moving core center axle and the little axle close fit of expansion link, when electromagnetically operated valve often leaves, moving core center axle promotes the little axle of expansion link and moves down, and that realizes expansion link and driving-disc limit shaft circumferentially intersects self-locking.

Further, the lateral balance line of the installation dimension of moving core center axle should be less than the effective range 5mm of electromagnetically operated valve lower surface.

Further, the radial diameter of moving iron core should be less than and equals 12.5mm.

Further, moving iron core directly should be less than or equal to 23.5mm to height H.

Further, tapering is made in moving iron core top, contributes to moving iron core movable in sleeve pipe.

Further, the use material of moving iron core adopts the high-carbon steel that phosphorus content is higher to make, the carbon steel that for example phosphorus content is greater than 45/10000ths.
