Description
Technical field
The utility model relates to electric loader, especially a kind of mounting structure of electric loader hydraulic pump.
Background technique
The steering system and work system of electric loader are driven by steering pump and working barrel respectively, steering pump and working barrel
It is mounted on gearbox, is driven by main motor, main motor is responsible for the traveling of electric loader, in the idle situation of main motor
Under, the steering system and work system of electric loader can not act, and steering system and work system is needed to need when work
Start main motor, increases power consumption.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of mounting structures of electric loader hydraulic pump, to reduce
Energy consumption.
The utility model solve its technical problem the technical solution adopted is that:
A kind of mounting structure of electric loader hydraulic pump, including hydraulic pump, electric motor for pump, hydraulic pump and electric motor for pump are logical
Shaft coupling connection is crossed, hydraulic pump and electric motor for pump are separately mounted on bracket, and bracket is fixed in the inside of Rear frame.
The utility model by adopting the above technical scheme, compared with prior art, beneficial effect is:
Structure is simple, and hydraulic pump is driven using individual electric motor for pump, and low energy consumption, at low cost.
Further, the prioritization scheme of the utility model is:
Bracket is fixed in left stringer or the inside of right vertical beam of Rear frame.
Hydraulic pump is duplex pump, including steering pump and working barrel, the oil inlet of steering pump and working barrel respectively with hydraulic oil
The oil outlet of case connection, steering pump and working barrel is connected to the oil inlet of turning gradient control valve respectively.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment；
In figure: Rear frame 1；Left stringer 1-1；Right vertical beam 1-2；Gearbox 2；Turning gradient control valve 3；Hydraulic pump 4；Shaft coupling
5；Electric motor for pump 6；Bracket 7；Main motor 8；Frequency converter 9；Battery pack 10.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
Referring to Fig. 1, a kind of mounting structure of electric loader hydraulic pump, by duplex hydraulic pump 4, shaft coupling 5, electric motor for pump
6, electric motor for pump 6 and bracket 7 are constituted.Gearbox 2 and main motor 8 is longitudinally intermediate is arranged in Rear frame 1, after bracket 7 is welded on
The left stringer 1-1 of vehicle frame 1 or the inside of right vertical beam 1-2.
Hydraulic pump 4 is mounted on bracket 7 by bolt, and it is by working barrel and steering pump structure that hydraulic pump 4, which is duplex gear pump,
At integrated pump.The oil inlet of steering pump and working barrel passes through pipeline respectively and is connected to hydraulic oil container, steering pump and working barrel
Oil outlet passes through fluid pressure line respectively and is connected to the oil inlet of turning gradient control valve 3.
Electric motor for pump 6 is mounted on bracket 7 by bolt, and hydraulic pump 4 is located at the front of electric motor for pump 6, hydraulic pump 4 and pump
It is connected with motor 6 by shaft coupling 5.Electric motor for pump 6 is connect by route with frequency converter 8, and frequency converter 8 passes through route and battery pack
10 connections.
The utility model separates hydraulic pump from gearbox, drives duplicate gear using individual electric motor for pump
Pump, reduces the power consumption of main motor.Duplex gear pump takes full advantage of the space in Rear frame, and structure is simple.
The above is only the preferred feasible embodiment of the utility model, not thereby limits to the power of the utility model
Sharp range, it is all with the variation of equivalent structure made by the utility model specification and accompanying drawing content, it is both contained in the utility model
Interest field within.
