Abstract
The utility model discloses a kind of electric oil hybrid excavator of multi-motor driving, it comprises power unit, powershift unit, hydraulic pump, described power unit comprises group of motors and internal combustion engine, described group of motors is connected the input of powershift unit with internal combustion engine, the output of powershift unit is connected with the input of hydraulic pump, described hydraulic pump switches its power input source by powershift unit, and described group of motors is composed in parallel by the motor of more than two.The utility model solves the motor space layout difficulty of electric oil hybrid excavator, reduces manufacture difficulty, reduces costs.
Description
Technical field
The utility model relates to a kind of excavator, particularly relates to a kind of electric oil hybrid excavator of multi-motor driving.
Background technology
Electricity oil hybrid excavator is a kind of energy-conservation engineering machinery, at present both at home and abroad hybrid excavator motor and motor be furnished with series and parallel connections two kinds of modes.But existing series system has the following disadvantages: (1) motor cost is high, and is only applicable to specific model, is unfavorable for industrialization; (2) dismounting of motor, maintenance are inconvenient.Then there is the deficiency of the large and difficult arrangement of motor volume in existing parallel way.
Therefore, reduce the layout of hybrid excavator motor, maintenance difficulty is the important directions that excavator is studied.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides the electric oil hybrid excavator that a kind of volume is little, manufacture simple multi-motor driving.
The technical solution adopted in the utility model is:
A kind of electric oil hybrid excavator of multi-motor driving, it comprises power unit, powershift unit, hydraulic pump, described power unit comprises group of motors and internal combustion engine, described group of motors is connected the input of powershift unit with internal combustion engine, the output of powershift unit is connected with the input of hydraulic pump, described hydraulic pump switches its power input source by powershift unit, and described group of motors is composed in parallel by the motor of more than two.
Described group of motors and internal combustion engine all can drive hydraulic pump.
The single motor work of described group of motors drives hydraulic pump separately, or the multiple motors of described group of motors works simultaneously and jointly drives hydraulic pump.
Described powershift unit comprises interlocking clutch, and the power input source of described hydraulic pump is switched between group of motors and internal combustion engine by interlocking clutch.
Described motor unit and internal combustion engine realize interlocking by interlocking clutch.
The utility model adopts above technical scheme, the power unit of group of motors and internal combustion engine composition, and by powershift unit interlocking clutch as required switch motor group or internal combustion engine as the power input source of hydraulic pump, and group of motors is designed to composed in parallel by the motor of more than two, user can enable single motor or multiple motors according to actual needs and work simultaneously and provide Power output.The utility model solves the motor space layout difficulty of electric oil hybrid excavator, reduces manufacture difficulty, reduces costs.Have during electricity and drive excavator work by group of motors, can noise be reduced, emissions reduction, significantly reduce construction cost; No diesel engine during electricity, transition is convenient, improves the compliance of the rate of attendance and operation, and powershift is convenient simultaneously, is expected alternative existing excavator.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details;
The structural representation of the electric oil hybrid excavator of a kind of multi-motor driving of Fig. 1 the utility model.
Detailed description of the invention
As shown in Figure 1, the electric oil hybrid excavator of a kind of multi-motor driving of the utility model, it comprises power unit, powershift unit 1, hydraulic pump 2, described power unit comprises group of motors 3 and internal combustion engine 4, described group of motors 3 is connected the input of powershift unit 1 with internal combustion engine 4, the output of powershift unit 1 is connected with the input of hydraulic pump 2, described hydraulic pump 2 switches its power input source by powershift unit 1, and described group of motors 3 is composed in parallel by the motor 31 of more than two.
Described group of motors 3 and internal combustion engine 4 all can drive hydraulic pump.
The single motor 31 of described group of motors 3 works and drives hydraulic pump 2 separately, or the multiple motors 31 of described group of motors 3 works simultaneously and jointly drives hydraulic pump 2.
Described powershift unit 1 comprises interlocking clutch, and described hydraulic pump 2 switches its power input source by interlocking clutch between group of motors 3 and internal combustion engine 4.Described powershift unit comprises interlocking clutch, and the power input source of described hydraulic pump is switched between group of motors and internal combustion engine by interlocking clutch.
Described motor unit 3 and internal combustion engine 4 realize interlocking by interlocking clutch.
The utility model adopts above technical scheme, the power unit of group of motors and internal combustion engine composition, and by powershift unit interlocking clutch as required switch motor group or internal combustion engine as the power input source of hydraulic pump, and group of motors is designed to composed in parallel by the motor of more than two, user can enable single motor or multiple motors according to actual needs and work simultaneously and provide Power output.The utility model solves the motor space layout difficulty of electric oil hybrid excavator, reduces manufacture difficulty, reduces costs.Have during electricity and drive excavator work by group of motors, can noise be reduced, emissions reduction, significantly reduce construction cost; No diesel engine during electricity, transition is convenient, improves the compliance of the rate of attendance and operation, and powershift is convenient simultaneously, is expected alternative existing excavator.
