Abstract

The invention provides a static iron core of an automatic gearbox of an electric car or an electric tricycle. The static iron core is made of stainless iron materials. The static iron core is characterized in that M12*1 outer threads are formed at the upper end of the static iron core, M16*1inner threads are formed at the lower end of the static iron core, the bottom of the outer threads and the bottom of the inner threads at the two ends of the static iron core are provided with O-shaped grooves, and a through hole is formed in the center of the static iron core.

Description

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

Technical field

The present invention relates to electric automobiles, particularly relate to the static 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 the concrete enforcement of the port foot application number small-power AMT automatic speed regulating differential motor patented technology that is 2014101425545, present patent application has proposed a kind of new production program.

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 stainless iron as raw material, connect firmly the expansion link operating room and the sleeve pipe that is arranged on electromagnetically operated valve endoporus of gearbox by two ends screw thread, can make motor vehicle in the time advancing operation, adopt unidirectional drive, in the time reversing gear operation, adopt bi-directional drive, direct effect of the present invention be vehicle under steam when off-position drive system depart from speed changer reducing gear and motor magnetic resistance, strengthen coasting ability, extend the ability that continues.

The technical scheme of the static iron core of electric automobile of the present invention, electro-tricycle automatic gear-box is, made by stainless iron raw material, it is characterized in that static iron core upper end is shaped with M12 × 1 external screw thread, lower end is shaped with M16 × 1 internal thread, be shaped with O shape groove at the bottom of thread at two ends, static iron core center is shaped with perforation.

The static iron core of electric automobile of the present invention, electronic three wheel automatic gear-box, be applied to the automatic gear-box of the single planetary gear speed-reduction of electric automobile, the electro-tricycle that need to possess gear reversing function, act on being connected and the drive path of expansion link of gearbox and electromagnetically operated valve, the art of this patent can make motor vehicle in the time of forward drive, adopt one-direction driving apparatus, in the time reversing gear driving, electromagnetically operated valve often leaves, moving iron core promotes expansion link, the limit shaft of expansion link and speed changer forms and circumferentially intersects spacingly, and realization is fixed the bi-directional drive of sun gear.

The static iron core of electric automobile of the present invention, electronic three wheel automatic gear-box, O shape circle is installed in the O shape groove of the static iron core two end bottoms of thread, O shape circle acts on the sealing that gearbox gear oil leaks outside, static iron core upper external screw thread connects firmly the internal thread of sleeve pipe, the lower end external screw thread of static iron core connects firmly expansion link operating room internal thread, and the central hole of static iron core acts on expansion link transmission operating path; The bottom face of static iron core limits the distance of stretch out and draw back of expansion link.

Described static iron core central hole diameter 6mm is preferred feature.

Accompanying drawing explanation:

Fig. 1 is static iron core schematic diagram;

Fig. 2 is that static iron core and sleeve pipe and motor junction chamber connect firmly schematic diagram.

Embodiment:

The invention discloses the static iron core of electric automobile, electro-tricycle automatic gear-box, as shown in Figure 1, 2, made by stainless iron raw material, it is characterized in that static iron core upper end is shaped with M12 × 1 external screw thread 2, lower end is shaped with M16 × 1 internal thread 5, be shaped with O shape groove at the bottom of thread at two ends, static iron core center is shaped with perforation 1.

The static iron core of electric automobile of the present invention, electronic three wheel automatic gear-box, 10mmO shape circle 3 is installed in the O shape groove 3 of static iron core upper external screw thread 2 bottoms, at static iron core lower end external screw thread 5 bottom O shape grooves 4,14mmO shape circle is installed, O shape circle acts on the sealing that gearbox gear oil leaks outside, static iron core upper external screw thread 2 connects firmly the internal thread of sleeve pipe, the lower end external screw thread 5 of static iron core connects firmly expansion link operating room internal thread, and the central hole 1 of static iron core acts on expansion link transmission operating path; The bottom face 6 of static iron core limits the distance of stretch out and draw back of expansion link.
