Specific embodiment
To enable above-mentioned purpose of the present utility model, feature and advantage more obvious understandable, below by specific embodiment party
Formula is described in further detail to the utility model.
" one embodiment " or " embodiment " referred to herein refers to that may be included in the side of realization of the utility model at least one
Special characteristic, structure or characteristic in formula." in one embodiment " that different places occur in this manual not refers both to
Same embodiment, nor the single or selective embodiment mutually exclusive with other embodiment.
Fig. 1 is referred to, in a specific embodiment, the electric motor car shunting self shifter that the utility model is provided subtracts
Fast device includes motor 1, input shaft 2, the first jackshaft 3, the second jackshaft 6 and output shaft 8.The motor 1 and institute
State input shaft 2 to connect, input shaft gear 10 is fixed with the input shaft 2.It is low first to be fixed with first jackshaft 3
Fast gear 4, the high gear 12 of reduction gearing 11 and first, first high gear 12 with diameter greater than the reduction gearing 11
Diameter, the diameter with diameter greater than first low-speed gear 4 of the reduction gearing 11.It is fixed on second jackshaft 6
Be provided with the second low-speed gear 5, shaft gear 14, the second high gear 17, bidirectional electromagnetic valve 15, gear shifting actuating mechanism 16, reversing hold
Row mechanism 13 and bidirectional clutch 7, the diameter with diameter greater than second high gear 17 of second low-speed gear 5, institute
State the diameter with diameter greater than the shaft gear 14 of the second high gear 17.
The bidirectional electromagnetic valve 15 coordinates the gear shifting actuating mechanism 16 to control the rotation of second high gear 17, institute
The rotation that reversing executing agency 13 controls the shaft gear 14 is stated, the bidirectional clutch 7 controls second low-speed gear 5
Rotate.
Differential gear 9 is fixed with the output shaft 8.
The input shaft gear 10 is connected with the engagement of the reduction gearing 11, first low-speed gear 4 and described second
The engagement connection of low-speed gear 5, first high gear 12 is connected with second high gear 17 engagement, the shaft gear 14
It is connected with the engagement of the differential gear 9.
During electric motor car ground zero, motor 1 is rotated forward, and input shaft gear 10 drives reduction gearing 11 to rotate, and first
The synchronous axial system of 4 and first high gear of low-speed gear 12.The bidirectional electromagnetic valve 15 is realized by controlling the bidirectional clutch 7
The idle running of second high gear 17；Second low-speed gear 5 transfers a torque to the second jackshaft 6, in described second
Countershaft 6 is transferred a torque on output shaft 8 by the shaft gear 14, and the output shaft 8 is transmitted moment of torsion by differential gear 9
To motor rear axle.Now, the velocity of rotation of motor rear axle is slow, and the startup torsion of electric motor car is larger, and decelerator is in and advances
Bottom gear running status.
When the travel speed of electric motor car reaches predetermined value, the bidirectional electromagnetic valve 15 is by controlling the bidirectional clutch
7 rotations for realizing second low-speed gear 5 and second high gear 17.Now, second low-speed gear 5 is in sky
Turn state, not transmitting torque；Moment of torsion is transferred to first jackshaft 3 by second high gear 17 from the input shaft 2,
First jackshaft 3 is transferred a torque on the second jackshaft 6, and second jackshaft 6 will be turned round by the shaft gear 14
Square is transferred on output shaft 8, and the output shaft 8 transfers a torque to motor rear axle by differential gear 9.Now, electric motor car
Back axle velocity of rotation is very fast, and torque value is smaller, and decelerator automatically switches to advance top gear fortune from advance bottom gear running status
Row state.
When electric motor car is moveed backward, motor 1 is rotated backward, and input shaft gear 10 transfers a torque to the reduction gearing
11, reduction gearing 11 drives first jackshaft 3 to rotate.Now, the bidirectional electromagnetic valve 15 by control it is described it is two-way from
The cooperation of clutch 7 causes that second high gear 17 dallies, while first low-speed gear 4 transfers a torque to described second
On low-speed gear 5, second low-speed gear 5 transfers a torque to the second jackshaft 6, and the second jackshaft 6 passes through the axle tooth
Wheel 14 is transferred a torque on the output shaft 8, and the output shaft 8 transfers a torque to motor rear axle by differential gear 9.
Now, the velocity of rotation of motor rear axle is slow, and the reversing torsion of electric motor car is larger, and decelerator is in reverse gear shift running status.
In the present embodiment, except the motor 1 and the bidirectional electromagnetic valve 15 are located at the casing 18 of the decelerator
Outside outer, remaining part is placed in the inside of the casing 18 of the decelerator.The motor 1 uses brshless DC motor.
Certainly, in other embodiments, it would however also be possible to employ alternating current generator.
It can be seen that, electric motor car shunting self shifter decelerator of the present utility model provides low-speed forward gear, advances at utmost speed
Gear, three gears of reverse gear shift, and low-forward range and the gear that advances at utmost speed can realize automatic switchover under certain condition, and change
The part that will not be damaged inside decelerator during gear.
Described above fully discloses specific embodiment of the present utility model.It is pointed out that being familiar with the neck
Any change that the technical staff in domain is done to specific embodiment of the present utility model is all without departing from right of the present utility model
The scope of claim.Correspondingly, the scope of claim of the present utility model is also not limited only to foregoing specific embodiment party
Formula.
