The first clutch and the second clutch are both unidirectional overrunning clutches, and the directions of the first clutch and the second clutch are opposite. The first clutch or the second clutch is a controllable bidirectional electromagnetic clutch. The dual gear shift mechanism can cause a reducer output shaft to output different rotating speed under the condition that the steering is not changed, the control is very convenient, the structure is simple and reliable, and simultaneously, as the bidirectional electromagnetic clutch is adopted, the aim of backing a car can be easily achieved.
Description
Technical field
The utility model relates to machine driven system, the two gears of particularly a kind of electric motor car.
Background technique
Electric bicycle is faced with two kinds of different travelling states with electric vehicle at present, on level road, travel at ordinary times, the load of car is little, motor output torque is less, and output power is little, if car when climbing, need bigger torque, the motor corresponding output power is big, if make motor that maximal efficiency be arranged when level road moves, motor can be done forr a short time, the torque of motor when climbing is 2～4 times of level road, the peak torque in when climbing just can not be very big like this, if it is big to require motor to have a torque, and power that just must the increase motor, motor is when level road moves so, be used in the very little place of torque, utilization efficiency is not very high, in other words, motor is not to be used in most effective some during level road, if when climbing the reduction speed ratio of speed reducer is increased, the torque of speed reducer output increases the corresponding reduction of its rotating speed so; High efficiency in the time of both can having guaranteed if desired to move on level road can be exported big torque again when climbing, efficient is higher.So just must use the two-stage gearbox, one-level is that motor slows down on the level road, and one-level is used in the climbing, should increase the cost of equipment like this, increases the volume of speed reducer again.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, the easy to operate two gears of a kind of electric motor car that can reduce the reducing gear volume again,
For achieving the above object, the technical solution adopted in the utility model is the two gears of a kind of electric motor car, comprises driving gear, and its innovative point is:
A, driving gear and the engagement of first driven gear, first driven gear is in transmission connection by the first clutch and first driving gear, first driving gear and reducer output shaft gear engagement;
B, driving gear and the engagement of second driven gear, second driven gear is in transmission connection by the second clutch and second driving gear, and second driving gear is connected with the reducer output shaft gear transmission through the transition gear.
Described first clutch and second clutch are unidirectional super clutch, and first clutch is opposite with the direction of second clutch.
Described first clutch or second clutch are the controllable bidirectional magnetic clutch.
After adopting said structure, driving gear is installed on the main shaft of motor, as long as change turning to of electric machine main shaft, by being in transmission connection of two mono-directional overrun clutchs and gear train, just can make the lace reducing device output shaft turning to the different speed of output under the constant situation easily, control very convenient, simple in structure, reliable, if electric motor car simultaneously requires reversing, overrunning clutch is become the bi-directional electromagnetic clutch, be easy to just can reach the purpose of reversing.
The two gears of electric motor car of the present utility model can also be used for as wind-driven generator, tital generator or the like, no matter how turning to of impeller, can both keep generator input shaft sense of rotation identical, make DC generator keep identical output electrode and output voltage, do not need with carrying out AC rectification after the AC motor generating.Such mechanism also can be used for various machinery controls, as ac synchronous motor, need not control the traffic direction of motor during startup, motor is by such mechanism, can make the defeated axle of motor go out the sense of rotation operation that requires according to us forever, not be subjected to the actuating motor direction different and different.Some ac synchronous motors just can not consider that electricity starts directed problem as long as can start like this.
Description of drawings
Fig. 1 is the structural representation of the two gears of the utility model electric motor car.
Embodiment
The embodiment who provides below in conjunction with accompanying drawing describes in further detail the two gears of electric motor car of the present utility model.
Referring to Fig. 1, the two gears of a kind of electric motor car comprise driving gear 1, and its innovative point is:
A, driving gear 1 and 2 engagements of first driven gear, first driven gear 2 is in transmission connection by the first clutch 2-1 and first driving gear 3, first driving gear 3 and 7 engagements of reducer output shaft gear;
B, driving gear 1 and 4 engagements of second driven gear, second driven gear 4 is in transmission connection by the second clutch 4-1 and second driving gear 5, and second driving gear 5 is in transmission connection through transition gear 6 and reducer output shaft gear 7.
Described first clutch 2-1 and second clutch 2-2 are mono-directional overrun clutch, and first clutch 2-1 is opposite with the direction of second clutch 2-2.
Described first clutch 2-1 or second clutch 2-2 are the controllable bidirectional magnetic clutch.
Referring to Fig. 1, the utility model in use, driving gear 1 is installed on the motor shaft, operation (just changeing) clockwise, 2 operations counterclockwise of first driven gear, because first driven gear 2 drives unidirectional (postive direction) first and surmounts to clutch 2-1, first driving gear 3 is moved counterclockwise, thereby drive reducer output shaft gear 7 and retarder shaft is rotated in the forward clockwise.
If motor shaft moves counterclockwise, driving gear 1 moves (counter-rotating) counterclockwise, 4 operations clockwise of second driven gear, because second driven gear 4 drives unidirectional (in the other direction) second and surmounts to clutch 4-1, second driving gear 5 is moved counterclockwise, move counterclockwise thereby drive transition gear 6, transition gear 6 drives reducer output shaft gear 7 and the retarder shaft still keeps being rotated in the forward clockwise.
Therefore no matter whether forward and reverse operation of motor, the sense of rotation of retarder shaft is same direction all the time.Because two kinds of drive paths its number of teeth difference when gear engagement, thereby motor is clockwise and when rotating counterclockwise, the rotating speed of the shaft of retarder is different, promptly two of this retarder kinds of reduction speed ratio are different, thereby reach with the different purpose of motor positive and inverse control retarder speed ratio, want speed fast thereby can reach operation on level road such as electric motor car, the efficient height, motor volume is little, and needs speed slow in when climbing operation, and the big and efficient of driving torque is also wanted high purpose.
If overrunning clutch is changed into the bi-directional electromagnetic clutch, so just can reach the purpose of electric motor car requirement reversing.
