Description
Technical Field
The utility model relates to an electric loader, especially an electric loader's hydraulic pump connection structure.
Background
At present, the national atmospheric pollution treatment strength is getting bigger and bigger, and enterprises are required to save energy, reduce emission and win the guard war of the blue sky. The loader is used as an engineering machine and has a wide application range, such as engineering construction, factories and mines, ports and the like. The traditional loader adopts a diesel engine as power, has high horsepower and is large in discharge. The electric loader solves the problem of emission of the traditional loader and is suitable for the requirements of national new energy. The working system and the steering system of the electric loader are in hydraulic transmission, the gearbox needs hydraulic gear shifting, all hydraulic pumps are needed to provide power, three motors are needed by using three hydraulic pumps, and the cost is high.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a connection structure of hydraulic pump of electronic loader, the hydraulic pump of trigeminy pump structure is by a motor drive.
The utility model provides a technical scheme that its technical problem adopted is:
a hydraulic pump connecting structure of an electric loader comprises a motor and a hydraulic pump, wherein an output shaft of the motor is connected with an input shaft of the hydraulic pump, the hydraulic pump is of a triple pump structure, the hydraulic pump sequentially comprises a first pump body, a second pump body and a third pump body from back to front, an oil inlet of the first pump body is communicated with an oil outlet pipe of a hydraulic oil tank, and an oil outlet of the first pump body is communicated with a distribution valve; an oil inlet of the second pump body is communicated with an oil outlet pipe of the hydraulic oil tank, and an oil outlet of the second pump body is communicated with a constant flow valve of the steering system; the oil inlet of the third pump body is communicated with the oil outlet of the oil pan of the gearbox, and the oil outlet of the third pump body is communicated with the oil inlet at the top of the gearbox.
Adopt above-mentioned technical scheme the utility model discloses compare with prior art, beneficial effect is:
three hydraulic systems adopt hydraulic pumps with a triple pump structure, and are compact in structure and low in cost.
Drawings
Fig. 1 is a schematic diagram of an embodiment of the present invention;
in the figure, a motor 1; a hydraulic pump 2; a first pump body 2-1; a second pump body 2-2; a third pump body 2-3; (ii) a A constant flow valve 3; a rear frame 4; a gearbox 5; an oil outlet 5-1 of the oil bottom shell; a top oil inlet 5-2; a front frame 6; a dispensing valve 7.
Detailed Description
The invention is further described with reference to the following figures and examples.
Referring to fig. 1, a hydraulic pump connection structure of an electric loader is composed of a motor 1, a hydraulic pump 2, a constant flow valve 3, a rear frame 4, a transmission case 5, a front frame 6, and a distribution valve 7. An output shaft of the motor 1 is connected with an input hollow shaft of the hydraulic pump 2, and the motor 1 and the hydraulic pump 2 are respectively arranged in a rear frame 4 of the electric loader.
The hydraulic pump 2 is of a triple pump structure, the hydraulic pump 2 sequentially comprises a first pump body 2-1, a second pump body 2-2 and a third pump body 2-3 from back to front, the first pump body 2-1 is a working pump, the second pump body 2-2 is a steering pump, and the third pump body 2-3 is a variable speed pump. The oil inlet of the first pump body 2-1 is communicated with an oil outlet pipe of a hydraulic oil tank (not shown in the figure), and the oil outlet of the first pump body 2-1 is communicated with a distribution valve 7. An oil inlet of the second pump body 2-2 is communicated with an oil outlet pipe of the hydraulic oil tank, and an oil outlet of the second pump body 2-2 is communicated with a constant flow valve 3 of the steering system. An oil inlet of the third pump body 2-3 is communicated with an oil outlet 5-1 of an oil pan of the gearbox 5, and an oil outlet of the third pump body 2-3 is communicated with an oil inlet 5-2 at the top of the gearbox 5.
The above description is only a preferred and practical embodiment of the present invention, and not intended to limit the scope of the present invention, and all structural equivalents made by using the contents of the specification and drawings are included in the scope of the present invention.
