Specific embodiment
Technical solution of the present invention is further elaborated below with reference to examples and drawings.
Embodiment 1
It present embodiments provides one kind 2 and keeps off deceleration device, comprising: motor 1, shell 2,2 keep off driving gear 3, one-way clutch
Device 4,1 keeps off driving gear 5, input shaft 6, output shaft 7, differential mechanism 8, friction clutch 9,2 and keeps off the gear driven tooth of driven gear 10,1
Wheel 11 and baffle 12.
Baffle 12 is provided in the shell 2, shell 2 is divided into left and right two chambers by the baffle 12；The motor 1
It is fixed in the right chamber of shell 2；The input shaft 6 is rotatably arranged on the side wall of baffle 12 and shell 2, and with
Motor 1 connects, and the power of motor 1 is passed to deceleration device；The one-way clutch 4 is arranged on input shaft 6, and unidirectionally from
The input terminal of clutch 4 is connect with input shaft 6；It is described 1 gear 5 empty set of driving gear on input shaft 6, and with one-way clutch 4
Output end connection；The output shaft 7 is rotatably arranged on the side wall of baffle 12 and shell 2, and parallel with input shaft 6；Institute
It states 1 gear driven gear 11 to be arranged on output shaft 7, and is engaged with 1 gear driving gear 5；The 2 gear driving gear 3 is arranged defeated
Enter on axis 6；The friction clutch 9 is arranged on output shaft 7, and the output end of the friction clutch 9 and output shaft 7 connect
It connects；2 gear, 10 empty set of driven gear is connect on output shaft 7, and with the input terminal of friction clutch 9；The differential mechanism 8 is set
Set in the left chamber of shell 2, and connect with output shaft 7, the differential mechanism 8 can by power transmission to transmission shaft and wheel,
To drive vehicle movement.
In the present embodiment, the 1 gear driving gear 5,1 keeps off driven gear 11,2 and keeps off the gear driven gear of driving gear 3,2
10, one-way clutch 4 and friction clutch 9 are arranged in the left chamber of shell 2.
The present embodiment is further described with reference to the accompanying drawing.
It is illustrated in figure 21 gear power transmission line figure.
At this point, friction clutch 9 separates, motor 1 drives 2 gear driving gears 3 to rotate by input shaft 6, to drive defeated
2 gear driven gears 10 on shaft 7 rotate, since 2 gear driven gears are that sky is set on the output shaft, and friction clutch 9 and 2 is kept off
Driven gear 10 is discrete state, therefore 2 gear driven gears not will drive the rotation of friction clutch 9, will not drive output shaft 7
Rotation.The power of motor 1 passes to one-way clutch 4 by input shaft 6, since the revolving speed of 4 input terminal of one-way clutch is greater than
Or it is equal to output end revolving speed, one-way clutch 4 is in torsion pass state, and one-way clutch 4 imparts power to 1 gear driving tooth at this time
Wheel 5, and output shaft 7 is passed to by 1 gear driven gear 11, and then pass to differential mechanism 8.
It is illustrated in figure 32 gear power transmission line figures.
At this point, friction clutch 9 engages, motor 1 drives 2 gear driving gears 3 to rotate by input shaft 6, to drive defeated
2 gear driven gears 10 on shaft 7 rotate, since the gear driven gear 10 of friction clutch 9 and 2 at this time is engagement state, 2
Gear driven gear 10 imparts power to friction clutch 9, and friction clutch 9 imparts power to output shaft 7 again, and then transmits
To differential mechanism 8.Because the output end revolving speed of one-way clutch 4 is greater than input terminal revolving speed, so one-way clutch 4 is in idle running shape
State will not transmit torque to 1 gear driving gear 5, therefore 1 gear driving gear 5 and 6 power of input shaft disconnect.
In the present invention, 1 gear and 2 gear switching only need to by control friction clutch 9 separation with combination can be realized,
When friction clutch 9 separates, deceleration device work keeps off state 1；When friction clutch 9 engages, deceleration device works 2
Gear state.This structure shift process is simple, quick, and power failure-free and shift shock.
The sequencing of above embodiments is not only for ease of description, represent the advantages or disadvantages of the embodiments.
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
Present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: it still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features；
And these are modified or replaceed, technical solution of various embodiments of the present invention that it does not separate the essence of the corresponding technical solution spirit and
Range.
