Embodiment

With reference to Figure of description, the present invention is described in further detail with embodiment：

Embodiment one：

As shown in fig. 1, it is a kind of it is compound after auxiliary room prolonged type load limiting type of constant filling fluid coupling, it is including input shaft 1, output shaft 3, defeated It is even to enter gear pair 4, connection output gear 5, connection input gear pair 6, freewheel clutch 7, rear auxiliary room prolonged type moment-limited hydraulic Clutch 8, output gear wheel set 9, planetary gear 20, the small gear ring 21 of input, output are provided between described input shaft 1 and output shaft 3 Bull gear 22, fixed carrier 23, output planetary frame 24, conjugation tooth ring 25, input gear 26, input planet carrier 27, input tooth Circle 28, output gear 29, small gear ring 21 is inputted by the planetary gear 20 in fixed carrier 23 with exporting bull gear 22, consolidating Determine the cooperating of planet carrier 23, the input 71 of fixed carrier 23 and freewheel clutch 7 couples with retaining element, exports Bull gear 22 couples with coupling the input gear 61 of input gear pair 6, and the output gear 62 of connection input gear pair 6 is with coupling Gear ring 25 couples, and conjugation tooth ring 25 passes through the planetary gear 20 on output planetary frame 24 and output planetary frame 24, input gear 26 Cooperating, output planetary frame 24 couple with coupling the input gear 51 of output gear 5, couple the output gear of output gear 5 52 couple with input gear ring 28, and input gear ring 28 is by inputting the planetary gear 20 on planet carrier 27 with inputting planet carrier 27, defeated Go out the cooperating of gear ring 29, input planet carrier 27 couples with the output gear 42 of input gear pair 4, input gear 26, input tooth The input gear 41 of wheel set 4 and the output end 72 of freewheel clutch 7 are defeated with rear auxiliary room prolonged type load limiting type of constant filling fluid coupling 8 Go out the connection of end 82, the input 81 of rear auxiliary room prolonged type load limiting type of constant filling fluid coupling 8 and the output gear 92 of output gear wheel set 9 Connection, the input gear 91 and input little gear 21 of output gear wheel set 9 couple with input shaft 1, output gear 29 and output shaft 3 connections.

The power that conjugation tooth ring 25, input gear 26 are delivered to this by the planetary gear 20 on output planetary frame 24 converges Flow and be delivered to input gear ring 28 through coupling output gear 5 in output planetary frame 24, output planetary frame 24, input planet carrier 27th, gear ring 28 is inputted again by inputting 20 power flow concentrations for being delivered to this of planetary gear on planet carrier 27 in output gear 29。

Because the rotating speed relations of distribution of above-mentioned each element can change, two-way power flow will be according to rotating speed between the two The change of distribution and change, when input gear 26, input planet carrier 27 rotating speed be zero when, conjugation tooth ring 25, input gear ring 28 Then reduction of speed increases square, when the rotating speed of input gear 26, input planet carrier 27 constantly raises, output planetary frame 24, output gear 29 Rotating speed also increase, that is to say, that when input gear 26, input planet carrier 27 rotating speed change when, output planetary The rotating speed of frame 24, output gear 29 and output shaft 3 also changes therewith.

Input power is two-way power dividing through input shaft 1, and the first via is delivered to rear auxiliary room and prolonged through output gear wheel set 9 Long formula load limiting type of constant filling fluid coupling 8, rear auxiliary room prolonged type load limiting type of constant filling fluid coupling 8 split into two-way, are delivered to all the way defeated again Enter gear 26, another way is delivered to input planet carrier 27 through input gear pair 4；Second tunnel is through inputting small gear ring 21, then by solid Power is delivered to output gear wheel 22 by the planetary gear 20 determined on planet carrier 23, and output gear wheel 22 inputs tooth by coupling again Wheel set 6, is delivered to conjugation tooth ring 25, and conjugation tooth ring 25, input gear 26 pass through the planetary gear 20 on output planetary frame 24 This power flow concentration is delivered in output planetary frame 24, then through coupling output gear 5, is delivered to input gear ring 28, it is defeated Enter planet carrier 27, input gear ring 28 again by inputting 20 power flow concentrations for being delivered to this of planetary gear on planet carrier 27 in defeated Go out gear ring 29, then be delivered to output shaft 3, it is achieved thereby that the power of engine is externally exported by output shaft 3.

For the present invention, when the rotating speed of input shaft 1 is constant, on output planetary frame 24, output gear 29 and output shaft 3 Moment of torsion changes with the change of its rotating speed, and rotating speed is lower, is delivered on output planetary frame 24, output gear 29 and output shaft 3 Moment of torsion it is bigger, conversely, then smaller, in the process, rear auxiliary room prolonged type load limiting type of constant filling fluid coupling 8 also plays the work of bending moment With so as to realize that the present invention can change the compound rear auxiliary room prolonged type of torque and speed with the difference of vehicle travel resistance Load limiting type of constant filling fluid coupling.

The present invention is in use, set that the input power of engine, input speed and its load are constant, i.e. the rotating speed of input shaft 1 It is constant with moment of torsion, before vehicle starting, the rotating speed of output shaft 3 is zero, and the input power of engine is delivered to defeated through input shaft 1 Enter small gear ring 21, then power is delivered to by the planetary gear 20 in fixed carrier 23 by output gear wheel 22, export canine tooth Wheel 22 is delivered to conjugation tooth ring 25 again by coupling input gear pair 6, wherein, due to now without power or fewer work( The input 71 that rate flows into input gear 26, input planet carrier 27 and freewheel clutch 7 couples with retaining element, plays limitation The effect of steering, make input gear 26, input planet carrier 27 turn to can not with the steering of input on the contrary, rotating speed is zero, now, Be delivered to the power of conjugation tooth ring 25, then by 20 power flow concentrations for being delivered to this of planetary gear on output planetary frame 24 in Output planetary frame 24, then through coupling output gear 5, input gear ring 28 is delivered to, input gear ring 28 passes through line of input again 20 power flow concentrations for being delivered to this of planetary gear in carrier 27 are in output gear 29, then are delivered to output shaft 3, work as transmission Moment of torsion onto output shaft 3, when being transferred to that caused tractive force is enough to overcome vehicle starting resistance on driving wheel through transmission system, Automobile is then started to walk and starts to accelerate, and the rotating speed of the output end 82 of rear auxiliary room prolonged type load limiting type of constant filling fluid coupling 8 also gradually increases, Associated input gear 26, the rotating speed also gradually increase therewith for inputting planet carrier 27, so that output planetary frame 24, output The moment of torsion of gear ring 29 and output shaft 3 is reduced with the increase of rotating speed.
