, can in three sun gear, gear ring and planet carrier primary elements it can be seen from the general principle of planetary gears Optional two, respectively as driving link and driven member, and make another element fixed (making the element rotating speed be zero) or make it Motion is by certain constraint (rotating speed for making the element is certain certain value), then whole train is i.e. with certain gearratio passing power. Different connections and fixed solution can obtain different gearratios, and the various combination of three primary elements can have 6 kinds of different groups Conjunction scheme.
The present invention considers from control strategy, if only considering two free degree controls, it is ensured that forward and backward output shaft turns Square is controlled, but can not adjust engine working point and be additionally provided accessory power to realize, and four frees degree are controlled from reason By being above possible, but it is not easily controlled in practice, so present invention selection Three Degree Of Freedom control is rational.To realize three The free degree controls, it is assumed that each part is only connected with a planetary gears node, for an engine, two it is defeated For the transmission system that shaft, six parts of three groups of hydraulic pump/motors (and/or motor) form, because each planet row has Three nodes, therefore be enough using three rows of planetary gear mechanisms.One engine, two output shafts, three groups of hydraulic pump/motors (and/ Or motor), the rotating speed (i.e. torque) of any three parts determines that other any rotating speed, torques all can be uniquely true among these It is fixed, it is achieved that Three Degree Of Freedom controls, it is by engine and hydraulic pump/motor (and/or motor) realization pair in practice The control of two output shafts.
Similarly, to realize that dual output control (by transmission system, realizes the output torque of former and later two output shafts respectively Or the independent accurate output and control of rotating speed), it is inevitable at least to need two groups of hydraulic pump/motors, while two outputs can not be expert at In star transmission coupled directly or indirectly, it otherwise will be unable to realize and independently control.
So the group of engine+three hydraulic pump/motor (and/or motor) is enough to realize dual output, Three Degree Of Freedom control System；Moreover, by the switching of the open and-shut modes of two clutches, it can make transmission system that there are two mode of operations, respectively Go for different traveling demands, one is to run at a low speed operating mode, and one is operating mode of running at high speed, and can also realize and reverse gear Traveling；Moreover, because hydraulic pump/motor and motor can also individually or mixing is applied to the system can be realized Pure hydraulic-driven or electric drive or electro-hydraulic combination drive, and the recovery of braking energy.Respectively arrange tooth in the planetary gears Gear ratio, the torque of the engine, the rotary inertia of the hydraulic pump/motor, torque and the rotating speed feature of circle and sun gear, The power joint all exported according to vehicle demand matches.
Three hydraulic pump systems shown in Fig. 2 and Fig. 3 are illustrated that each function is realized respectively below：
Under the larger speed operation of demand torque such as startup or climbing, second clutch 8 closes, while first clutch 7 disconnect, and forward and backward output shaft 4,5 can export high pulling torque, and this is mode of operation one.In mode of operation for the moment, it is possible to achieve mixing Power is run at a low speed.The power of engine 3 passes through the planet carrier C1 of first row, the gear ring R2 of second row, the sun gear of second row S2, the sun gear S3 of the 3rd row are delivered separately to forward and backward output shaft 4,5, realize that dual output drives, are typically carried in straight-line travelling For equal driving torque.Simultaneously according to the demand of output torque, second group of hydraulic pump/motor 22 and the 3rd group of liquid can be adjusted Press rotating speed and the torque of pump/motor 23.Other engine 3 can be stored up by first group of hydraulic pump/motor 21 to hydraulic accumulator Energy is deposited, or to other electrical equipment electricity consumptions of vehicle, and first group of hydraulic pump/motor 21 can be controlled by rotational speed regulation and started The operating point of machine, improve the operating efficiency of engine.With the increase of front and rear output rotating speed, first clutch 7 closes, simultaneously Second clutch 8 disconnects, and is switched to mode of operation two, under mode of operation two, it is possible to achieve run at high speed.Two kinds of mode of operations Switching condition be that, when needing slave pattern one to be switched to pattern two, the rotating speed of second group of hydraulic pump/motor 22 is zero, simultaneously First clutch 7 and second clutch 8 are manipulated together, it is possible to achieve the steady switching of pattern.Under mode of operation two, realize mixed Close power to run at high speed, now engine, three hydraulic pump/motor co-ordinations, adjusted according to output speed and torque respective Rotational speed and torque, first group of hydraulic pump/motor 21 can control the operation interval of engine by adjusting itself rotating speed.
Further, when the rotating speed of hydraulic pump/motor described in one of which is 0, corresponding to the group hydraulic pump/horse When the input that reaches, output gearratio are 0.5~1, it is adapted to high-performance cruise operating mode；Corresponding to the defeated of the group hydraulic pump/motor Enter, export gearratio for 1.5~4 when, be adapted to low rate start operating mode.
When reversing gear traveling, closed using first clutch 7, while the pattern two that second clutch 8 disconnects, it is now described Engine is in work or off position, by adjusting first group of hydraulic pump/motor and the 3rd group of hydraulic pump/motor Rewind function is realized in rotating speed and torque.Rotating speed and the torque of engine and first group of hydraulic pump/motor 21 are adjusted simultaneously, to realize Higher power demand, under can realizing that engine does not work by the rotating speed of first group of hydraulic pump/motor 21 of adjustment in addition Pure hydraulic energy reverse travel.
Pure hydraulic-driven：Under mode of operation one or mode of operation two, by controlling second group of He of hydraulic pump/motor 22 The output torque size of 3rd group of hydraulic pump/motor 23 realizes forward and backward output shaft driving torque, by controlling rotating speed to realize speed Size controls, while adjusts the rotating speed of engine 3 and first group of hydraulic pump/motor 21 so that engine peed stable zero or Allow rotating speed to dally, realize the pure hydraulic energy traveling that no engine participates in.Simultaneously can be by controlling first group of hydraulic pump/motor 21, realize the start-up course of engine.
The realization of Brake energy recovery：In braking procedure, engine 3 no longer provides torque, and rotating speed is gradually decreased as 0, By taking mode of operation one as an example, during braking, due to the 3rd group of hydraulic pump/motor 23 and second group of hydraulic pump/motor 22 respectively with it is preceding Output, rear output shaft intercouple, and the 3rd group of hydraulic pump/motor 23 and second group of hydraulic pump/motor 22 can be by caused by brakings Mechanical energy is converted into hydraulic energy and is stored in accumulator 1, while first group of hydraulic pump/motor 21 can adjust output torque to meet Torque-demand, while adjust rotating speed and ensure that the rotating speed of engine 3 does not increase, so as to realize the recovery of braking energy.
It is described above, mainly tell about the preferable embodiment of the present invention by taking hydraulic-driven as an example, but the present invention Protection domain is not limited thereto, any one skilled in the art the invention discloses technical scope in, can The change or replacement readily occurred in, it should all be included within the scope of the present invention.
