Described low-speed clutch 9 is located between secondary annulus 3 and casing, is designed to Normally closed type.
Described continuous driving force input switching mechanism comprises continuous driving force input shaft 2, high speed driving wheel 1, high speed driven wheel 5, high-speed clutch 6, middling speed driving wheel 16, middling speed driven wheel 14, middle speed clutch 15.Described continuous driving force input shaft 2 with between middling speed driving wheel 16 for being fixedly connected with; Described middle speed clutch 15 is located at the internal gear of middling speed driven wheel 14 and first planet train that is between the first internal gear 13, is designed to open in usual; Described continuous driving force input shaft 2 with between high speed driving wheel 1 for being fixedly connected with; Described high-speed clutch 6 is located at the sun gear of high speed driven wheel 5 and the second planetary gear train that is between the second sun gear 7, is designed to open in usual.
As shown in Figure 1, if continuous driving force input shaft 2 counterclockwise rotates; Initial state low-speed clutch 9 combines, and middle speed clutch 15 is thrown off, and high-speed clutch 6 is thrown off, and whole mechanism is in low gear; When speed governing power input shaft 11 rotating speed is zero, output wheel 12 rotating speed is zero.
Above-mentioned rotary speed direction sees from right to left according to Fig. 1, lower same; If be counterclockwise forward.
1., if make output wheel 12 speedup, process is as follows:
1.1, under low gear state, forward increases the rotating speed of speed governing power input shaft 11;
Under this state, secondary annulus 3 is fixed, the first internal gear 13 and the second sun gear 7 freely driven.Based on secondary annulus 3, between speed governing power input shaft 11 and planet carrier 4, speed ratio is negative value, and planet carrier 4 will drive output wheel 12 oppositely speedup;
When the rising of speed governing power input shaft 11 rotating speed forward makes the rotating speed of its rotating speed and continuous driving force input shaft 2 reach a specific ratio, the rotating speed of output wheel 12 reaches the interface point of bottom gear and mid ranger slewing range, is now homodyne speed between the first internal gear 13 and middling speed driven wheel 14;

Speed clutch 15 in disengagement;
Now whole mechanism enters High gear state, because the combination of high-speed clutch 6 is early than the disengagement of middle speed clutch 15, so whole gearshift procedure does not occur power interruption;
1.5, under high gear state, reduce the reverse speed of speed governing power input shaft 11 to zero-speed, then continue forward and increase its rotating speed;
Under this state, the second sun gear 7 obtains a reverse fixed rotating speed by high speed driving wheel 1 and high speed driven wheel 5 from continuous driving force input shaft 2, and the first internal gear 13 and secondary annulus 3 are freely driven.Based on the second sun gear 7, between speed governing power input shaft 11 and planet carrier 4, speed ratio is negative value, thus speed governing power input shaft 11 oppositely slow down and forward speedup process in, planet carrier 4 will drive the reverse speedup of output wheel 12;
In the process that the rotating speed of speed governing power input shaft 11 oppositely reduces or forward raises, the rotating speed of output wheel 12 will reach the high-end of top gear slewing range, the namely the highest output speed of whole gear.
2., if make output wheel 12 slow down, its process is contrary with process 1.The main points of gearshift procedure are: first cut, rear disengagement, to avoid power interruption.
Fig. 2 has showed the corresponding relation between the rotating speed of each primary component in speed-change process and output wheel rotating speed.Horizontal ordinate: output wheel rotating speed; Ordinate: element rotating speed.100 is the corresponding relation line of continuous driving force input shaft 2,101 is the corresponding relation line of speed governing power input shaft 11,102 is the corresponding relation line of the second sun gear 7,103 is the corresponding relation line of secondary annulus 3,104 is the corresponding relation line of planet carrier 4, and 105 is the corresponding relation line of the first internal gear 13.
