In order to make those skilled in the art be more fully understood that this utility model scheme, below in conjunction with the accompanying drawings and be embodied as
The utility model is described in further detail for mode.
Refer to a kind of concrete of the electric speed reducing mechanism that Fig. 3 and Fig. 4, Fig. 3 are electric motor car provided by the utility model
The structural representation of embodiment；Fig. 4 is a kind of concrete real of the electric speed reducing mechanism of electric motor car provided by the utility model
Execute another structural representation of mode.
The electric speed reducing mechanism of the electric motor car that this utility model detailed description of the invention provides, including motor 1 and decelerator 2,
Also include for anti-stopping power by output shaft 4 back transfer of decelerator 2 to the isolator 5 of motor 1, wherein, isolator 5 with subtract
Speed device 2 is connected, and motor 1 is as driving means, and the rotating shaft of motor 1 is coaxially disposed with the power shaft 3 of decelerator 2 and fixes and is connected,
The output shaft 4 of decelerator 2 is for being connected with the wheel shaft of electric motor car.
Wherein it should be noted that isolator 5 specifically has multiple, by outer ring, inner ring and be located between Internal and external cycle and
For realizing the compositions such as the voussoir of inner ring and outer ring unidirectional locking, its effect is to be only capable of single direction transmission, and isolator 5 can be prevented
Stopping power by output shaft 4 back transfer of decelerator 2 to motor 1, i.e. under the effect of isolator 5, power be only capable of by motor 1 to
The output shaft 4 direction transmission of decelerator 2.
Using the electric speed reducing mechanism that this utility model provides, when giving electricity, motor 1 is passed to by 5 power of isolator
The output shaft 4 of decelerator 2, output shaft 4 drives vehicle axles to rotate, normal vehicle operation, need not at descending or level road motor 1
When giving electricity, vehicle axles continues to rotate, and under the effect of isolator 5, vehicle axles will not transmit power to motor 1, i.e. will not
Rotated by decelerator 2 drive motor 1 axle, thus reduce motor 1 and be lost, increase motor 1 life-span, extend in the continuation of the journey of battery
Journey, reduces electric motor car advance resistance.
The electric speed reducing mechanism of the electric motor car that this utility model detailed description of the invention provides, isolator 5 is with decelerator 2 even
Connecing, isolator 5 can be located at multiple position, and specifically, isolator 5 can be located on output shaft 4, and driven on output shaft 4
Gear 6 is rotatably connected with output shaft 4, and the outer ring of isolator 5 is fixing with driven gear 6 to be connected, the inner ring of isolator 5 and output
Axle 4 is fixing to be connected；When electricity given by motor 1, the inner ring of isolator 5 and outer ring are in lockup state, and the outer ring of isolator 5 drives inner ring
Synchronous axial system, i.e. driven gear 6 pass to output shaft 4 by 5 power of isolator and travel for vehicle, when motor 1 does not gives electricity, single
Being in, to inner ring and the outer ring of device 5, the state of freeing, isolator 5 will not transmit power to driven gear 6, i.e. vehicle axles rotates,
But gear and motor 1 in decelerator 2 will not rotate, and therefore decrease gear wear, reduce motor 1 and are lost, thus increase
Gear and the life-span of motor 1, also reduce the resistance not advanced to electric motor car during electricity simultaneously.
Isolator 5 is located on output shaft 4, when motor 1 does not gives electricity, all gears in decelerator 2 can be made not turn
Dynamic, can maximized reduction gear wear, it addition, the driven gear 6 on output shaft 4 is relatively large in diameter, isolator 5 can be facilitated
Installation；The decelerator 2 usually two stage reducer of electric motor car, the driven gear 6 on output shaft 4 is then two grades of driven gears.
Isolator 5 can certainly be located on power shaft 3 or jackshaft 7, as long as output shaft 4 reverse power transmission can be prevented to motor
1, all within protection domain of the present utility model.
The electric speed reducing mechanism of the electric motor car that this utility model detailed description of the invention provides, can be accomplished in several ways
Driven gear 6 is rotatably connected with output shaft 4, and one of which is relatively simple, be widely used and reliable way is driven
Between gear 6 and output shaft 4, bearing is set, specifically, sliding bearing can be selected.
It is connected additionally, the inner ring of isolator 5 is fixing with output shaft 4, dismantles for convenience, the inner ring of isolator 5 and output
Can be with interference fit and by bonded between axle 4；The outer ring of isolator 5 is fixing with driven gear 6 to be connected, for the side of installation
Just, the groove for placing isolator 5, the outer ring of such isolator 5 and driven gear can be provided with in one end of driven gear 6
Can be with interference fit and by bonded between 6, convenient dismounting；Certainly, between inner ring and the output shaft 4 of isolator 5, Yi Jidan
To selecting other fixing connected modes such as welding between the outer ring of device 5 with driven gear 6, as long as guaranteeing normally to pass
Dynamic, all within protection domain of the present utility model.
On the basis of above-mentioned each detailed description of the invention, isolator 5 has polytype to select, and specifically can select spine
Wheel clutch, pawl clutch is made up of ratchet, ratchet, thumb wheel, spring and pin etc., and ratchet is equivalent to outer ring, with driven
Gear 6 is fixing to be connected, and its inner rim is provided with ratchet, and thumb wheel is equivalent to inner ring, fixes with output shaft 4 and is connected, and pawl extremity is located to be dialled
On wheel.Under the action of the spring, ratchet front end the most upward, embeds in the teeth groove of ratchet, when electricity given by motor 1, and pawl clutch
Being in the state of locking, driven gear 6 drives pawl wheel, and ratchet drives thumb wheel to rotate by ratchet, and then thumb wheel drives output
Axle 4 rotates output power；When motor 1 does not gives electricity, thumb wheel rotating speed is more than ratchet rotating speed, and ratchet front end departs from ratchet teeth groove, output
Axle 4 can not be by pawl clutch transmission power to driven gear 6, i.e. vehicle axles rotates, but the gear in decelerator 2 and electricity
Machine 1 will not rotate, and is achieved in the single-direction transmission of electric speed reducing mechanism.Pawl clutch can transmit torque greatly, reliable and stable, when
So, it is also possible to selecting the other kinds of isolators such as free wheeling sprag clutch, as long as being prevented from power reverse transmission, all existing
Within protection domain of the present utility model.
On the basis of above-mentioned detailed description of the invention, in order to improve connection reliability, it is also possible to directly on driven gear 6
Process ratchet, will the outer ring of pawl clutch one-body molded with driven gear 6, during assembling, successively by pawl clutch
Inner ring, driven gear 6 etc. are arranged on output shaft 4；The outer ring of pawl clutch is one-body molded with driven gear 6, processing
Convenient, install reliable.
Except above-mentioned electric speed reducing mechanism, detailed description of the invention of the present utility model also provides for one and includes above-mentioned electronic subtract
The electric motor car of speed mechanism, the structure of these other each several parts of electric motor car refer to prior art, repeats no more herein.
