As shown in fig.1, the utility model is further, the first transmission mould group includes intermeshing first defeated
Enter gear 41 and the first ratchet 42, the second transmission mould group includes that intermeshing second input gear 51 and second is single
To gear 52, the first input gear 41 and the second input gear 51 are mounted on power input shaft 1, can be connected by keyway arrangements
It connects, in this way rotates synchronously the first input gear 41, the second input gear 51 and power input shaft 1.3 output power of motor is to dynamic
When power input shaft 1, the first input gear 41 and the second input gear 51 is driven to rotate together.First ratchet 42 and
Two ratchets 52 are mounted on power output shaft 2, are rotated together under 42 normality of the first ratchet with power output shaft 2, the
Two ratchets 52 then dally with respect to power output shaft 2 under normal conditions.In this way, the first input gear 41 is nibbled in initial drive
The first ratchet 42 of transmission is closed, so that power output shaft 2 be driven to rotate together, output power obtains one grade of low speed；And at this moment
The second input gear 51 and the second ratchet 52 engagement formed idle running.In the present embodiment, 51 He of the second input gear
The transmission ratio of second ratchet 52 is greater than the transmission ratio of the first input gear 41 and the first ratchet 42.First ratchet
42 and second ratchet 52 connect with power output shaft 2 by isolator respectively；It is unidirectional at the first ratchet 42 in figure
Device is directly fixedly connected with power output shaft 2；Isolator at second ratchet 52 is fixedly connected with the second ratchet 52,
And after power output shaft 2 reaches certain revolving speed pass through high speed shift propeller 53 and high speed connector 54 under the action of realize with
Power output shaft 2 connects.Second ratchet, 52 specific works are: high speed shift propeller 53 follows power output shaft 2 to rotate,
When power output shaft 2 reaches certain revolving speed, high speed shift propeller 53, which is thrown away, pushes high speed connector 54, makes high speed connector
54 move axially along power output shaft 2 and connect the isolator built in the second ratchet 52, reach the second ratchet of connection
52, it can be transferred power on power output shaft 2, be obtained by the second input gear 51 and the engagement of the second ratchet 52 in this way
Two grades of power output at a high speed.And at this moment, since the transmission ratio of the second input gear 51 and the second ratchet 52 is greater than first
The transmission ratio of input gear 41 and the first ratchet 42, the isolator built in the first ratchet 42 are reached in power output shaft 2
It is opposite after to certain revolving speed to be separated with the first ratchet 42, thus the first input gear 41 and the first ratchet 42 at this moment
Engagement forms idle running.
As shown in fig.1, the power output shaft 2 is equipped with the output gear of connection rear axle tooth box assembly 6 in the present embodiment
Wheel 21 realizes that the power of power output shaft 2 is exported by gear drive to rear axle tooth box assembly 6.In figure, 1 He of power input shaft
The setting of 2 parallel side-by-side of power output shaft, power input shaft 1 directly connect with the output end axis of motor 3, and structure is simple, small, lead to
Power input shaft 1 and the cooperation of power output shaft 2 and the first transmission mould group and the second transmission mould group alternately transmitting power are crossed, is realized more
Shelves output power, energy-saving effect is more preferable, reduces the load of direct current generator, can effectively extend the use of direct current generator and battery
Service life.
As shown in fig.1, also assembling reverse gear 7 on the power output shaft 2 in the present embodiment, reverse gear 7 includes reversion
Link block 71 and flexible connection block 72, reversion link block 71 and power output shaft 2 are connected, and are flexibly connected block 72 and first and are driven mould
Group linkage；When motor 3 rotates forward, it is flexibly connected block 72 and is separated with reversion link block 71；Conversely, being flexibly connected block when motor 3 inverts
72 are connected with reversion link block 71.The structure realization reverse gear work while, also simplify the structure of device, reduction is fabricated to
This, promotes service performance.
As shown in fig.1, utility model works are as follows:
3 low speed output power of motor drives power input shaft 1 to rotate, 41 He of the first input gear on power input shaft 1
The engagement of first ratchet 42 transfers power on power output shaft 2, and power output shaft 2 is given by 21 output power of output gear
Rear axle tooth box assembly 6 realizes one grade of low speed work；At this moment, since 2 revolving speed of power output shaft is lower, 51 He of the second input gear
The engagement of second ratchet 52 forms idling conditions.When motor 3 accelerates output power that power input shaft 1 is driven to rotate, power is defeated
The first input gear 41 and the first ratchet 42 engagement entered on axis 1 transfers power on power output shaft 2, power output shaft
When 2 revolving speed is promoted and reaches certain revolving speed, high speed shift propeller 53, which is thrown away, pushes high speed connector 54, makes high speed connector 54
It is moved axially along power output shaft 2 and connects the isolator built in the second ratchet 52, reach the second ratchet 52 of connection,
Realize the second ratchet 52 transmitting power to power output shaft 2.At this moment the second input gear 51 and the second ratchet are utilized
52 transmission ratio is greater than the design of the transmission ratio of the first input gear 41 and the first ratchet 42, the revolving speed of power output shaft 2
Greater than the revolving speed that the first input gear 41 is transmitted to the first ratchet 42, thus the isolator at the first ratchet 42 is with servo-actuated
2 high speed rotation of power output shaft, and the first ratchet 42 relatively lags behind, and is formed reversely, thus it is detached from transfer motion power.Motor 3
Power then passes through power input shaft 1, the second input gear 51 and the second ratchet 52 and passes to power output shaft 2, and power is defeated
2 high speed rotation of shaft simultaneously passes through 21 output power of output gear to rear axle tooth box assembly 6, realizes two grades of work of high speed.Conversely, dynamic
From high speed toward when low speed variation, power transmitting is then passed from the second input gear 51 and the engagement of the second ratchet 52 power output shaft 2
Alternation turns to the first input gear 41 and the engagement transmitting of the first ratchet 42, and details are not described herein for concrete operating principle.
The utility model structure is simple, facilitates production and assembling, power input shaft and power output shaft cooperation transmitting power,
Realize top gear, low or first gear alternate-running automatically using revolving speed, so that the continuity for power of being more convenient for exports, especially climbing,
Heavy duty and muddy road conditions etc. when driving, can obtain biggish power (torque), to guarantee electric vehicle at low speeds
Smooth traveling.By multi gear output power, energy-saving effect is more preferable, reduces the load of direct current generator, can effectively extend direct current
The service life of motor and battery.
