Description

The driving disc spline of automatic transmission

Technical field

The utility model relates to electric automobiles, particularly relates to the driving disc spline of the automatic transmission that is applied to electric motor car.

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 calendar year 2001 China's electric power user 20,000 people only, short being developed so far in about ten years, are greater than 100,015,000, 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 China 863 and the 12 five-year plan, 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; For seeking better electric axle, drive operational effect, the technician in field has carried out the research of various transmission technologies, wishes to obtain larger output capability and meets very fast and load and climbing operation.For example we can be at disclosed patent documentation, existing market product, in technical forum, seeing artificer in field comprises, motor has been carried out to amplifying power, VCT, DVC transmission technology, clockwise and anticlockwise transmission technology, electromagnetism switches transmission technology etc., their ultimate aim is all that consistent hope obtains larger output torque, these transmission schemes, for example, while amplifying after power of motor specified rated efficiency point, efficiency is lower, shortened the ability of continuing, VCT, DVC speed change is because the ability of continuing has been shortened in inefficient belt and chain transmission equally, clockwise and anticlockwise, comprise that electromagnetism switches, these functions of manual shift all should obtain the support of other actions just can implement variable speed drives.

As electric power, be in operation and compare 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, increases output torque.

For the sixth of the twelve Earthly Branches disclosed China Patent No. be 201120027552.3 motor automatic transmission of electric vehicles, than other automatic speed changing patented technologies, have simple in structure, labor and material saving, practicability, market competitive power are strong, but technician not yet attempts the manufacturing process of driving disc spline to further investigate.

Summary of the invention

The utility model for complete China Patent No. be 201120027552.3 motor automatic transmission of electric vehicle manufacturing process, make automatic transmission guarantee that at work Proper Match, oil circuit are unimpeded, a kind of saturating cutter technique on aperture, inner circle wall that arranges on driving disc periphery wall is provided, make speed changer at work, gear oil is infiltrated to driving disc spline 2 internal diameters 5 by periphery wall aperture, can make friction factor and the reliability of automatic transmission and transmission shaft have basic change, the art of this patent is compact to design, reasonable, system effectiveness is high.

The driving disc spline of the utility model automatic transmission, spline outer radial diametric is 26mm, spline 2 internal diameters 5 are 20mm, the specification that it is characterized in that spline 2 numbers of teeth is 25 tooth 1 moduluses, at spline 2 outer radial periphery wall any places, be drilled with more than one aperture 3, between spline 2 inner circle walls, section is carried out cutter and is formed groove 1, and groove 1 has possessed the functional oil of holding in speed changer work, make speed changer at work, driving disc spline and transmission shaft are to obtain the lubricated friction that do not produce in rotation.

The driving disc spline of automatic transmission, step 4 is set below spline 2, step 4 close fit vertical with driving disc welding connect firmly, the speed of speed changer is exported by driving disc spline, spline 2 coordinates with driving gear, spline 2 internal diameters 5 and transmission shaft close fit, the process data of spline 2 is 25 tooth 1 moduluses, between spline 2 internal diameters 5 are suitably located to carry out, the saturating cutter of section forms groove 1, groove 1 acts on the oil that holds in speed changer when work, at spline 2 periphery wall any places, bore aperture 3, aperture 3 acts on the oil circuit input of speed changer work; In speed changer work, transmission shaft and driving disc spline rotating in same direction.

Fig. 2 is that spline 2 coordinates schematic diagram with driving disc.

Embodiment:

The utility model discloses the driving disc spline of automatic transmission, as shown in Figure 1 and Figure 2, spline 2 outer radial diametric are 26mm, spline 2 internal diameters 5 are 20mm, the specification that it is characterized in that spline 2 numbers of teeth is 25 tooth 1 moduluses, at spline 2 outer radial periphery wall any places, be drilled with more than one aperture 3, between spline 2 inner circle walls, section is carried out cutter and is formed groove 1, groove 1 has possessed the functional oil of holding in speed changer work, make speed changer at work, driving disc spline and transmission shaft are to obtain the lubricated friction that do not produce in rotation.

Technician is appreciated that, do not departing from situation of the present utility model and can suitably adjust disclosed configuration, 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 utility model be restricted by claims.
