System 7, dynamical system 7 includes 7.2 two kinds of power sources of internal combustion engine 7.1 and motor, and the internal combustion engine 7.1 typically uses diesel oil
Machine, it is also possible to use gasoline engine；To save space and being easy to switching, two kinds of power sources take serial arrangement to install, internal combustion engine 7.1
It is connected by main clutch 7.3 with motor 7.2, the switching of power source can be carried out by the folding of main clutch 7.3.
The dynamical system 7 is with the order of connection of hydraulic system 6：Internal combustion engine, clutch, motor, hydraulic system, i.e.,
The power of dynamical system 7 is directly output to the hydraulic pump of hydraulic system, is controlled by controlling the power output of engine
The ability to work of hydraulic system, making the linking of two systems becomes simple, efficient, further increases the adaptability of equipment.
In addition, when the work of motor 7.2 is only started, internal combustion engine 7.1 is stopped, and thus will cause internal combustion engine 7.1
Radiator fan is stalled, and causes temperature in power bin 2.2 too high, influences the normal work of hydraulic system.And if using installing wind additional
The mode of fan radiates for power bin 2.2, certainly will need to install extra equipment in vehicle body 2, the increased excavator of this aspect
Manufacturing cost, more importantly, the fan for newly installing additional the fan original-pack with internal combustion engine can be only one because of the selection of power source
Set fan is another set of idle in work, causes the wasting of resources, and the wind inlet of fan of new clothes to have a strong impact in power bin 2.2
Air-flow trend, reduce engine radiating effect.
The present embodiment is provided with an auxiliary-motor 7.1.2 in the position of the original fan 7.1.1 of institute's internal combustion engine 7.1, and in wind
Fan and fan clutch 7.1.3 is provided with the rotating shaft of 7.1.1, fan 7.1.1 is by fan clutch 7.1.3 and internal combustion engine 7.1
Pto connection.Auxiliary-motor 7.1.2 is provided with fan clutch 7.1.3, axle sleeve and the pair of fan 7.1.1 rotating shafts
Clutch is mutually connected on motor 7.1.2.Two fan clutch 7.1.3 are centrifugal clutch.When the work of internal combustion engine 7.1
When making, fan 7.1.1 rotations are driven by it, because auxiliary-motor 7.1.2 is coupled by centrifugal clutch with fan 7.1.1, therefore
It will not rotate；Conversely, when driving excavator to work by motor 7.2, main clutch 7.3 disconnects, internal combustion engine 7.1 is not sent out
Raw to rotate, now auxiliary-motor 7.1.2 starts, and drives fan 7.1.1 to rotate radiating, in the work of auxiliary-motor 7.1.2 will not drive
Combustion engine 7.1 is rotated.
Excavator described in the present embodiment uses hydraulic drive, the hydraulic system 6 include console 6.1, hydraulic pump 6.2,
Pipeline 6.3；Console 6.1 is located in driver's cabin 2.1；Hydraulic pump 6.2 is connected with the output shaft of dynamical system 7, and console 6.1 leads to
Pipeline 6.3 is crossed to be connected with hydraulic pump 6.2, equipment 5, running motor 4.1.
Second embodiment
As shown in Fig. 5~6, on the basis of previous embodiment, the present embodiment is provided with drum in the afterbody of the vehicle frame 1
8.The drum 8 includes base 8.1, take-up pulley 8.2, drum motor 8.3, cable 8.4, and base 8.1 is fixedly connected with vehicle frame 1,
The axle of take-up pulley 8.2 is connected on base 8.1, and take-up pulley 8.2 is connected with drum motor 8.3, and the outer rim of take-up pulley 8.2 is provided with gear
Line wheel 8.2.1, cable 8.4 is looped around on take-up pulley 8.2.The drum motor 8.3 operates sensor etc. to coordinate with excavator, can
Realize automatic deploying and retracting cable 8.4.
But under actual condition, excavator frame 1 is likely to relatively frequently left-right rotation, front and rear advance and retreat, makes cable 8.4 innings
Portion is bent with very small angles, easily causes the breakage of cable 8.4.Therefore, above-mentioned base 8.1 is also designed to fixed part
8.1.1 with rotating part 8.1.2 two parts, the two is hinged, and rotating part 8.1.2, can be with the case where running gear is not touched
Wide-angle swings, and can curve radius in effect increasing cable 8.4, slows down its strain.
The third embodiment
