The flexible rod of electric vehicle, electro-tricycle automatic transmission case
Technical field:
The present invention relates to electric automobiles, particularly relate to the flexible rod that is applied to electric vehicle, electro-tricycle automatic transmission case.
Background technique:
Electric control mechanical type automatic speed variator (Automated mechanicalTransmission, be called for short AMT), the feature of AMT speed variator 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 automatic speed changing can make driver realize automaitc shfit 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 artificer 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 velocity ratio, change motor operation curve, system is all moved in high efficiency section, and simple in structure, manufacture cost is lower, automaticity is higher, it can be made and being run slowly by speed changer according to electric 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 flexible rod 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 solenoid valve as power, promoting flexible rod by moving iron core moves up and down, can make electric vehicle in the time advancing operation, adopt unidirectional drive, intersect self-locking in when operation of reversing gear by flexible rod and drive plate position-limited shaft and realize bi-directional drive, direct effect of the present invention be vehicle under steam when off-position transmission system depart from speed changer reducing gear and motor magnetic resistance, strengthen coasting ability, extend mileages of continuation.
The flexible rod technological scheme of electric vehicle of the present invention, electro-tricycle automatic transmission case is, it is characterized in that there is step at flexible rod middle part, and there is little axle step top, and step below has mobile jib, the bottom of mobile jib to have the I-shaped groove of matrix.
Electric vehicle of the present invention, the flexible rod of electronic three wheel automatic transmission case, mobile jib and little axle are made one or composite assembly moulding, step and static iron core below end face offset, acting on flexible rod position limits, the little axle in step top coordinates with static iron core endoporus and moves iron core formation pushing mechanism, mobile jib is installed in flexible rod junction chamber, mobile jib radially outer mounting spring, acting on solenoid valve resets when normally closed, mobile jib below matrix I-shaped groove coordinates with speed changer driving disc position-limited shaft, backward running, when solenoid valve often leaves, matrix I-shaped groove forms circumferential self-locking enforcement the fixing sun gear of intersecting with position-limited shaft, when vehicle does to advance operation, solenoid valve is normally closed, flexible rod resets under spring action.
Embodiment of flexible rod of electric vehicle of the present invention, electro-tricycle automatic transmission case, described little axle, is characterized in that it is stainless steel 304 that little axle uses material, little axle and mobile jib are made one or are combined in one.
Further, the radial diameter of little axle is less than or equal to 8mm.
Described step, step radial diameter is less than or equal to 15mm, and step and static iron core below end face offset.
Described mobile jib, the radial diameter of mobile jib is less than or equal to 13mm, the radially outer mounting spring of mobile jib.
Described matrix I-shaped groove, matrix I-shaped groove is positioned at mobile jib below, and matrix I-shaped groove forms the circumferential self-locking that intersects with speed changer drive plate position-limited shaft in the time that solenoid valve often leaves.
Accompanying drawing explanation:
Fig. 1 is flexible rod schematic diagram;
Fig. 2 is the fundamental diagram of flexible rod under electromagnetic valve.
Embodiment:
The invention discloses the flexible rod of electric vehicle, electro-tricycle automatic transmission case, as shown in Figure 1, 2, it is characterized in that there is step 2 at flexible rod middle part, there is little axle 1 step top, and step below has mobile jib 3, the bottom of mobile jib to have the I-shaped groove 4 of matrix.
Embodiment of flexible rod of electric vehicle of the present invention, electro-tricycle automatic transmission case, described little axle 1, is characterized in that little axle 1 uses material for stainless steel 304, little axle 1 is made one or is combined in one with mobile jib 3.
Further, the radial diameter of little axle 1 is less than or equal to 8mm.
Described step 2, step 2 radial diameter are less than or equal to 15mm, and step and static iron core below end face offset.
Described mobile jib 3, the radial diameter of mobile jib 3 is less than or equal to 13mm, the radially outer mounting spring of mobile jib 3.
Described matrix I-shaped groove 4, matrix I-shaped groove 4 is positioned at mobile jib 3 belows, and matrix I-shaped groove 4 forms the circumferential self-locking that intersects with speed changer drive plate position-limited shaft in the time that solenoid valve often leaves.
Technician is appreciated that, can suitably adjust disclosed configuration without departing from the invention, therefore, example is only for the object of example rather than restriction as described above, it will be apparent to those skilled in that and recognize, in not obvious change aforesaid operations situation, can carry out little modification and reach identical object configuration or mounting process, the present invention be restricted by claims.
