[0024] The hydraulic energy drive assembly includes a gear pump 7, a hydraulic plunger pump 8, a radiator 9, a two-way hydraulic valve 10, a hydraulic oil tank 11, and a third speed increaser 12. The gear pump, hydraulic plunger pump, radiator, two-way hydraulic valve, hydraulic oil tank, and third speed increaser are connected in sequence, and the gear pump and the hydraulic oil tank are bidirectionally interconnected through the two-way hydraulic valve;

[0025] The universal standard components include a clutch 13, a gearbox 14, a transmission shaft 15, a differential 16, a half-shaft 17, and a driving wheel 18. The clutch, gearbox, transmission shaft, differential, half-shaft, and driving wheel are connected in sequence.

[0026] The first speed increaser and the second speed increaser are multi-stage gear speed increase structures, which achieve speed increase by cooperating with gears of different tooth ratios.

[0027] The two pump bodies of the duplex dual-pump gear pump are respectively a high-pressure pump and a low-pressure pump. The high-pressure pump is used to provide power hydraulic oil to the hydraulic plunger pump, and the low-pressure pump is used to assist the oil circulation and replenishment of the hydraulic energy drive component.

[0028] The hydraulic plunger pump includes a pump body, a rotor and a stator. The rotor rotates in the stator under the action of high-pressure hydraulic oil to convert hydraulic energy into mechanical energy.

[0029] It also includes a hydraulic oil filtering device, which is arranged on the oil circulation path of the hydraulic energy drive component to filter impurities in the hydraulic oil to ensure the normal operation of the hydraulic system.

[0030] The present invention also provides a method for using a hydraulic power machine, comprising the following steps:

[0031] Step 1001, initial power start-up step, the electric drive assembly uses a common 12V6ah battery as initial power, and makes the 12V6ah electric motor operate at a speed of 1500 rpm;

[0032] Step 1002, the speed increasing step, wherein the rotation of the motor is accelerated twice by the first speed increaser and the second speed increaser, so that the output speed reaches 2500-3000 rpm, driving the double-pump gear pump to work;

[0033] Step 1003, a hydraulic energy conversion step, wherein the dual-pump gear pump converts mechanical energy into hydraulic energy and outputs high-pressure hydraulic oil, which drives the hydraulic plunger pump to operate;

[0034] Step 1004, the step of increasing speed again and power output. After the hydraulic piston pump increases its speed through a speed increaser, the rotational speed reaches 2500 - 3000 revolutions per minute, and the output power is about 250 - 350 N·m. The power is transmitted to the vehicle wheels in sequence through the clutch, transmission, differential, and half shaft to drive the vehicle to travel.

[0035] During the operation of the hydraulic system, the hydraulic oil is filtered by a filtering device to remove impurities and cooled by a cooling device to ensure the stable operation of the hydraulic system.
