Description
Technical field
The present invention and transit equipment technical field, particularly a kind of electric motor car mechanical formula adaptive transmission.
Background technique
The major reason that current electric motor car fails to popularize is the scarce capacity that continues of battery, and according to relevant report, the reason of the scarce capacity that continues of battery is that the former capacity of battery is limit on the one hand, is the appearance because of large electric current on the other hand.Analyzing the origin cause of formation that large electric current occurs, is more often to occur at a high speed and heavy duty during due to driving, normally strengthens electric switch, thereby large electric current frequently occurs to making the scarce capacity that continues.
The large electric current of existing minimizing occurs can be by selecting different Transmitted chainss to mate different driving needs, and it is to adopt electromagnetic type that some technology of report is arranged at present, and the control mode of pneumatic type etc. is carried out the switching of different Transmitted chainss.Its mentality of designing is when needs conversion Transmitted chains, uses electromagnetism or pneumatic external force mode to change the connection form of mechanism.And the control mode of existing electromagnetic type or pneumatic type need to be introduced external force, increases corresponding control unit, makes complex structure, consumes the extra energy.The present invention does not need to introduce external force, does not use additional energy source, and structure is simpler.
a kind of " pure electric vehicle automatic transmission " is provided in prior art, see that publication number is: CN102734396A, open day be: the Chinese patent of 2012.10.17, this pure electric vehicle automatic transmission, comprise motor (1), casing (2), be arranged on input shaft (3) and output shaft (11) on casing (2), described input shaft (3) is provided with the first driving wheel (6) and the second driving wheel (5), the first driving wheel (6) is provided with forward one-way element (7), the second driving wheel (5) is provided with automatic clutch (4), forward one-way element (7) is fixedly connected with input shaft (3) with automatic clutch (4), be fixedly connected with the first follower (14) and the second follower (15) on output shaft (11), the first driving wheel (6) and the first follower (14) engagement, the second driving wheel (5) and the second follower (15) engagement.After adopting this structure, solve the deficiency that speed changer can not the automatic clutch speed change, had simple and reasonable, automatic speed changing, machine operation is stable, efficient is high, grade ability good.But this mechanism still can affect the working life of battery of electric vehicle, and when electric motor car went up a slope, battery also the phenomenon of large electric current can occur, so just diminished the working life of battery.
Summary of the invention

As shown in Figure 5, be the structural representation of fifth embodiment of the invention.Itself and the 3rd embodiment's distinctive points is: this electric motor car mechanical formula adaptive transmission comprises that also gear 27 is arranged on input shaft 5 for the gear 27 that slows down, and this gear 27 is positioned at the right of centrifugal clutch 3; Its effect is to make the rotating speed of output shaft 6 lower than the rotating speed of motor.
Wherein, the present invention also provides a kind of multistage automatic transmission that adopts electric motor car mechanical formula adaptive transmission, and this multistage automatic transmission is for to be connected in series a plurality of described electric motor car mechanical formula adaptive transmissions.
Working principle of the present invention is as follows:
When the electric motor car low speed driving, the power of motor drives outer ring rotating from input shaft by the double rolling key clutch inner ring, and this outer ring drives output shaft again, drives electric-vehicle wheel and moves ahead;
When the rotating speed of motor reached the centrifugal clutch setting value, power passed to the outer ring of double rolling key clutch from the centrifugal clutch outer ring by gear one, and the outer ring drives output shaft; Because gear one is accelerating function, when it passes to the outer ring of double rolling key clutch, speed is greater than the inner ring of double rolling key clutch, so inner ring does not drive output shaft this moment; Outer ring drive wheel by double rolling key clutch turns.The battery of electric motor car just the phenomenon of large electric current can not occur like this; It can extend the working life of battery of electric vehicle, improves the ability that continues of electric motor car, and does not need external energy, and in the time of can advancing with electric motor car, required drive is complementary.
When the rotating speed of motor during lower than the centrifugal clutch setting value, separate with the centrifugal clutch inner ring centrifugal clutch outer ring, the state when so just reverting to the electric motor car low speed driving.
If the motor counter-rotating, principle is constant.As long as friction speed is arranged thus, mechanism just can select corresponding Transmitted chains to realize the self adaption switching of two kinds of power voluntarily.
Gear two in this invention is to play decelerating effect, when motor rotates, the sun gear that just drives gear two rotates, because gear two ring gears are fixed, its planet carrier slows down and exports, and drives axle rotation in double rolling key clutch, and the interior axle (inner ring) of double rolling key clutch drives again double rolling key clutch outer shaft (outer ring) and rotates, thereby outputting power drives wheel turns, and this power is the power after controlling of slowing down.
Here what deserves to be explained is: input shaft of the present invention is wanted first to be related with centrifugal clutch, it is the inner ring that input shaft will drive centrifugal clutch, because of rotating speed not Danone drive the degree of centrifugal clutch outer ring, so do not drive the centrifugal clutch outer ring rotating, do not rotate therefore play the Transmitted chains of accelerating function.And the rotation of input shaft one side is with the inner ring of centrifugal clutch, the opposing party is also with the inner ring of double rolling key clutch, because this moment, the outer ring of double rolling key clutch was static, its rotating speed is lower than the inner ring of double rolling key clutch, therefore the inner ring of double rolling key clutch drives the outer ring of double rolling key clutch, the outer ring of double rolling key clutch is connected with output shaft, thereby realizes, output shaft is passed in the rotation of input shaft.When the rotating speed of motor reached the centrifugal clutch setting value, power passed to the outer ring of double rolling key clutch from the centrifugal clutch outer ring by gear one, and the outer ring drives output shaft; Because gear one is accelerating function, when it passes to the outer ring of double rolling key clutch, speed is greater than the inner ring of double rolling key clutch, so inner ring does not drive output shaft this moment; Outer ring drive wheel by double rolling key clutch turns.
The above is only preferred embodiment of the present invention, and all equalizations of doing according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
