In Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6,1 input shaft, 2 planet stent, 3 planetary gear, 4 gear ring, 5 sun gears 6 are defeated
13 gear ring internal tooth of shaft 7 jackshaft, 8 output shaft gear, 9 countershaft-gear, 10 connection gear, 11 transition gear, 12 gear ring external tooth, 14 row
15 gear ring frame of star support gear, 16 bearing
The embodiment of planet stent (2) is fixed in below by input shaft (1), and the present invention will be described in detail：
Input shaft (1) is fixed on the planet stent (2) of planetary gear mechanism, planetary gear (3) on planet stent (2) and
Sun gear (5) engages, sun gear (5) affixed output shaft (6), output shaft gear (8) and transition gear (11) on output shaft (6)
Engagement, transition gear (11) and countershaft-gear (9) engagement, the affixed countershaft-gear in jackshaft (7) both ends (9) and connection gear
(10), (10 and gear ring external tooth (12) engagement, gear ring internal tooth (13) and planetary gear (3) engage connection gear, and make gear ring (4) single
To rotation.
When the power that engine stop is motionless or provides cannot overcome vehicle friction power, vehicle is motionless or with certain at this time
Velocity inertia travels, vehicle output shaft (6) and output shaft gear (8) rotation, and drive transition gear (11) jackshaft when driving
Gear (9), connection gear (10), gear ring (4), planetary gear (3), sun gear (5) to output shaft (6) form the rotation of a closing,
Input shaft (1) is motionless, and the number of teeth that need to meet gear ring internal tooth (13) and gear ring external tooth (12) is equal, sun gear (5) and connection gear
(10) gear ratio is equal to input shaft gear (8) and countershaft-gear (9) gear ratio, and at this moment vehicle is neutral state, due to there is vehicle
The presence of frictional force, this velocity of rotation can be slower and slower.
Overcoming vehicle friction power when engine provides power, input shaft (1) and planet stent (2) are rotated with certain speed,
Rotating the planetary gear (3) on planet stent (2) increases, and drives the increase of sun gear (5) and output shaft (6) rotating speed and car speed
Increase, the rotating speed of output shaft (6) and output shaft gear (8) increases, and drives transition gear (11) countershaft-gear (9), tooth connection
The velocity of rotation that wheel (10), gear ring (4), planetary gear (3), sun gear (5) to output shaft (6) form closing is also continuously increased,
Car speed is continuously increased, and such input shaft (1) is getting faster with a certain rotational speed, output shaft (6) rotating speed, after a certain period of time
Rotating speed can very high and input shaft (1) rotating speed and output shaft (6) rotating speed it is unrelated, only with the rotating speed angular acceleration of input shaft (6) and
The acceleration of vehicle is related, and input shaft (1) and output shaft (6) do not need to select suitably to be driven do not need to gear shift mechanism when,
By stopping and rotating input shaft (1), with regard to the required speed of vehicle can be obtained, so as to achieve the purpose that speed change.
In Fig. 3, Fig. 4, input shaft (1) is fixed on sun gear (5) and is engaged with planet stent (2) upper planet wheel (3), row
The internal tooth (13) of star-wheel (3) and gear ring (4) engages, gear ring external tooth (12) and connection gear (10) engagement, in connection gear (10)
Affixed output shaft (6), the affixed output shaft gear of output shaft (6) other end (8), while planet branch affixed on planet stent (2)
Frame gear (14) is also engaged with output shaft gear (8), and one-directionally rotates support gear (14).In this embodiment, during neutral gear, vapour
Vehicle is in inertia downward driving, output shaft (6) rotation, makes gear output shaft (8), support gear (14), planetary gear (3), gear ring (4),
Connection gear (10) forms closing rotation, and input shaft (1) is motionless, need to meet gear ring internal tooth (13) gear ring external tooth (12) number of teeth phase
The number of teeth Deng, planet stent gear (14) is equal to sun gear (5) number of teeth plus gear ring internal tooth (13) number of teeth, connection gear (10) tooth
Number is equal with the number of teeth of output shaft gear (8).
In Fig. 5, Fig. 6, input shaft (1) is fixed in by gear ring frame (15) on gear ring (4), gear ring (4) upper ring gear internal tooth
(13) planetary gear (3) engagement and on planet stent (2), planetary gear (3) and sun gear (5) engagement, sun gear (5) affixed output
Axis (6), output shaft (6) is by embedded in the inner bearing (16) of support gear (14), affixed output shaft gear (8), planet stent (2)
On support gear (14) and connection gear (10) engagement, connection gear (10) affixed jackshaft (7), jackshaft (7) other end
Output shaft gear (8) engagement on affixed countershaft-gear (9) countershaft-gear (9) and output shaft (6), makes support gear (14)
One-directional rotation.
