As shown in fig. 1, the utility model provides a hybrid dynamic compactor of a first embodiment, including engine 1, transfer case 2, hydraulic pump 3, torque converter 4, first transmission shaft 5, gearbox 6, transmission case 7, second transmission shaft 8, reducing gear box 9, hoist 11, enlightening an organic whole motor 10; part of the power of the engine 1 is transmitted to the winch 11 through the transfer case 2, the hydraulic torque converter 4, the first transmission shaft 5, the gearbox 6, the transmission case 7, the second transmission shaft 8 and the reduction gearbox 9 in sequence, so that the rammer is lifted. The other part of power of the engine 1 is transmitted to the starting integrated motor 10 through the transfer case 2, the hydraulic torque converter 4, the first transmission shaft 5, the gearbox 6, the transmission case 7, the second transmission shaft 8 and the reduction gearbox 9 in sequence, so that the starting integrated motor 10 generates power. Another part of the power driving the engine 1 drives the hydraulic pump 3 through the transfer case 2.

The starting and starting integrated motor 10 is connected with the reduction gearbox 9, the storage battery 13 supplies power to the starting and starting integrated motor 10, and the starting and starting integrated motor 10 drives the winch 11 to rotate in an auxiliary mode through the reduction gearbox 9. When the rammer is lifted, the starting-up integrated motor 10 is in a driving mode, the engine 1 and the starting-up integrated motor 10 drive the winch 11 to rotate together, so that the lifting acceleration of the rammer is greatly increased, and under the condition of the same lifting force of the winch 11, the output power of the engine 1 is reduced. When the rammer is lowered to work, the dynamic compactor is in a no-load state, the engine 1 drives the starting integrated motor 10 to generate electricity through the reduction gearbox 9, and electric energy generated by the starting integrated motor 10 is stored in the storage battery 13, namely in a power generation mode. The controller 12 controls the ignition and integration motor 10 to change between a driving mode and a power generation mode according to the change of the working condition of the dynamic compaction machine.

The output shaft of the engine 1 is arranged along the X-axis direction, the winch 11 is arranged along the Y-axis direction, and the engine 1, the transfer case 2, the hydraulic torque converter 4, the first transmission shaft 5, the gearbox 6 and the transmission case 7 are arranged on the left side or the right side of the winch 11 and the reduction gearbox 9 along the X-axis direction; an input shaft of the transmission case 7 is arranged along the X-axis direction, an output shaft of the transmission case 7 is arranged along the Y-axis direction, and a second transmission shaft 8 is arranged along the Y-axis direction; the engine 1, the transfer case 2, the hydraulic torque converter 4, the gearbox 6, the transmission case 7, the reduction gearbox 9, the starting integrated motor 10 and the winch 11 are mutually independent units.

As is known to those skilled in the art, a non-rigid torque converter, in which the torque converter 4 uses fluid as a working medium, is one form of hydraulic drive. The torque converter 4 has a closed working chamber in which the fluid circulates, wherein the pump impeller, the turbine impeller and the stator impeller are connected to the input shaft, the output shaft and the housing, respectively. When the engine 1 drives the input shaft to rotate, the liquid flows out of the centrifugal pump impeller, sequentially passes through the turbine and the guide wheel and then returns to the pump impeller, and circularly flows. The pump wheel transfers the mechanical energy of the input shaft to the liquid. The high-speed liquid pushes the turbine to rotate, and energy is transmitted to the output shaft. The torque converter 4 transfers torque by the change of momentum moment caused by the interaction of fluid and blades. The main feature of the torque converter 4, which is different from a fluid coupling, is that it has a fixed stator. The guide action of the guide wheels on the fluid allows the output torque of the hydrodynamic torque converter 4 to be higher or lower than the input torque, and is therefore referred to as a torque converter. The ratio of the output torque to the input torque is called a torque conversion coefficient, and the zero-speed torque conversion coefficient when the output rotation speed is zero is usually about 2-6. The torque conversion coefficient decreases as the output rotation speed increases. The input shaft and the output shaft of the hydraulic torque converter 4 are in fluid communication, and working components are not rigidly connected. The torque converter 4 is characterized in that: impact and vibration can be eliminated, and the overload protection performance and the starting performance are good; the rotating speed of the output shaft can be greater than or less than that of the input shaft, and the rotating speed difference of the two shafts is different along with the magnitude of the transmission torque; the automatic transmission has good automatic speed change performance, the output rotating speed automatically decreases when the load increases, and otherwise, the output rotating speed automatically increases; the stable working area of the engine 1 is ensured, and the transient change of the load is basically not reflected on the engine 1. The efficiency of the hydraulic torque converter 4 is high near the rated working condition, and the highest efficiency is 85-92%.

The starting and starting integrated motor 10 is arranged on the reduction gearbox 9, and the power output by the engine 1 firstly passes through the hydraulic torque converter 4 and then is transmitted to the starting and starting integrated motor 10 through the reduction gearbox 9. The starting integrated motor 10 can absorb part of impact and vibration, so that the output power of the engine 1 and the load of the dynamic compactor are kept stable and optimally matched, and the output power of the engine 1 and the load of the dynamic compactor are prevented from being suddenly increased or decreased. The fuel consumption rate and the exhaust emission of the engine 1 are reduced, energy conservation and emission reduction are realized, the hammer lifting power is high, the acceleration is high, and the performance and the working efficiency of the whole engine are improved.

The techniques not described above are common general knowledge of the skilled person. The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
