Embodiment one：

As shown in fig. 1, a kind of buncher of composite constant charge type hydraulic coupler, including input shaft 1, output shaft 3, perseverance Fill formula fluid-flywheel clutch 4, input gear pair 5, freewheel clutch 6, connection gear pair 7, input gear 8, output gear wheel set 9, institute Provided with planetary gear 20, fixed carrier 21, input gear ring 22, output gear 23, connection between the input shaft 1 and output shaft 3 stated Connect planet carrier 24, input gear 25, output bull gear 26, input gear wheel 27, output planetary frame 28, input bull gear 29, defeated Go out gear 30, input planet carrier 31, input little gear 32, input gear ring 22, the permanent input 41 for filling formula fluid-flywheel clutch 4 with And the input gear 91 of output gear wheel set 9 couples with input shaft 1, input gear ring 22 passes through the planet tooth in fixed carrier 21 Wheel 20 and fixed carrier 21, the cooperating of output gear 23, the input 61 of fixed carrier 21 and freewheel clutch 6 with Retaining element couples, and output gear 23 couples with input gear 25, and input gear 25 is by coupling the planet on planet carrier 24 Gear 20 is with coupling planet carrier 24, the output cooperating of bull gear 26, input gear 8 and output bull gear 26 and input planet Frame 31 couples, and inputs planet carrier 31 by planetary gear 20 thereon and output gear 30, the input cooperating of little gear 32, Input little gear 32, the output end 62 of freewheel clutch 6 and couple the output gear 72 and input gear pair 5 of gear pair 7 Output gear 52 couples, and the input gear 71 of connection gear pair 7 couples with coupling planet carrier 24, the input of input gear pair 5 Gear 51 couples with the permanent output end 42 for filling formula fluid-flywheel clutch 4, and output gear 30 couples with input bull gear 29, and input is big Gear ring 29 passes through the planetary gear 20 on output planetary frame 28 and input gear wheel 27, the cooperating of output planetary frame 28, input Gear wheel 27 couples with the output gear 92 of output gear wheel set 9, and output planetary frame 28 couples with output shaft 3.

The power that connection planet carrier 24, input gear 25 are delivered to this by the planetary gear 20 coupled on planet carrier 24 Conflux in output bull gear 26, output bull gear 26 is delivered to input planet carrier 31, inputs planet again by input gear 8 The power flow concentration that frame 31, input little gear 32 are delivered to this by the planetary gear 20 inputted on planet carrier 31 is in output gear 30。

Because the rotating speed relations of distribution of each above-mentioned element can change, two-way power flow will be according to rotating speed between the two The change of distribution and change, when couple planet carrier 24, input little gear 32 rotating speed be zero when, input gear 25, input planet Then reduction of speed increases square to frame 31, when the rotating speed of connection planet carrier 24, input little gear 32 is constantly raised, output bull gear 26, output The rotating speed of gear 30 is also increased, that is to say, that when the rotating speed of connection planet carrier 24, input little gear 32 changes, The rotating speed of output bull gear 26, output gear 30 and output shaft 3 also changes therewith.

Input power is three tunnels power dividing through input shaft 1, and the first via is delivered to input canine tooth through output gear wheel set 9 Wheel 27；Formula fluid-flywheel clutch 4 is filled in second tunnel through perseverance, is delivered to input gear pair 5, and input gear pair 5 splits into two-way, one again Road is delivered to input little gear 32, and another road is delivered to connection planet carrier 24 through coupling gear pair 7；3rd tunnel is through inputting gear ring 22, and power is delivered to by the planetary gear 20 in fixed carrier 21 by output gear 23, then it is delivered to input gear 25, the power flow concentration that connection planet carrier 24, input gear 25 are delivered to this by the planetary gear 20 coupled on planet carrier 24 In output bull gear 26, then by input gear 8, input planet carrier 31, input planet carrier 31, input little gear are delivered to 32 power flow concentrations for being delivered to this by the planetary gear 20 inputted on planet carrier 31 are in output gear 30, output gear 30 Input bull gear 29 is delivered to again, and input gear wheel 27, input bull gear 29 pass through the planetary gear 20 on output planetary frame 28 This power flow concentration is delivered in output planetary frame 28, output planetary frame 28 is delivered to output shaft 3 again, it is achieved thereby that handle 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, export on bull gear 26, output gear 30 and output shaft 3 Moment of torsion changes with the change of its rotating speed, and rotating speed is lower, is delivered on output bull gear 26, output gear 30 and output shaft 3 Moment of torsion it is bigger, conversely, then smaller, in the process, perseverance fills formula fluid-flywheel clutch 4 and also plays bending moment, so as to realize The present invention can change the stepless of the composite constant charge type hydraulic coupler of torque and speed with the difference of vehicle travel resistance Speed changer.

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 gear ring 22, and power is delivered to by the planetary gear 20 in fixed carrier 21 by output gear 23, then be delivered to input Gear 25, wherein, due to now without or fewer power flow into connection planet carrier 24, input little gear 32, and surmount The input 61 of clutch 6 couples with retaining element, plays limitation and turns to, and makes connection planet carrier 24, input little gear 32 Turn to and now, the power of input gear 25 can not be delivered to the steering of input on the contrary, rotating speed is zero, then pass through and couple row The power flow concentration that planetary gear 20 in carrier 24 is delivered to this is in output bull gear 26, then passes through input gear 8, transmission To input planet carrier 31, the power flow concentration that input planet carrier 31 is delivered to this by planetary gear 20 thereon is in output gear Wheel 30, output gear 30 is delivered to input bull gear 29 again, and input gear wheel 27, input bull gear 29 pass through output planetary The power flow concentration that planetary gear 20 on frame 28 is delivered to this is in output planetary frame 28, and output planetary frame 28 is delivered to output again Axle 3, when the moment of torsion being delivered on output shaft 3, the tractive force produced on driving wheel is transferred to through transmission system and is enough to overcome automobile During breakaway force, automobile is then started to walk and starts to accelerate, and the rotating speed that perseverance fills the output end 42 of formula fluid-flywheel clutch 4 also gradually increases, with The connection planet carrier 24 being connected, input little gear 32 rotating speed also gradually increase therewith so that output bull gear 26, output The moment of torsion of gear 30 and output shaft 3 is reduced with the increase of rotating speed.
