Specific embodiment
The total design of the utility model is: the internal combustion engine and motor that excavator is equipped with are installed in parallel.The tool of above-mentioned apparatus
Body structure can there are many, all should belong to equivalent mechanical structure.Five kinds of embodiments are introduced with reference to the accompanying drawing:
The first embodiment: Fig. 1 describes a kind of excavator, is equipped with rack 1, traveling wheel 2, digger blade 3, digging arm 4 drives
Sail room 5, distributor 6, motor 7, internal combustion engine 8, fuel tank 9,.Traveling wheel 8 in figure is Athey wheel, is also possible to round wheel.It excavates
The engine of machine have with motor 7 and internal combustion engine 8, internal combustion engine mostly uses diesel engine.It is visible in conjunction with Fig. 2: motor 7 and internal combustion engine
8 drive respective hydraulic oil pump 10 respectively, and hydraulic oil pump 10 is designed with high-pressure oil pipe 11 and oil return pipe 13, internal combustion engine 8 it is hydraulic
The output end of the high-pressure oil pipe 11 for the hydraulic oil pump 10 that the high-pressure oil pipe 11 and motor 7 of oil pump 10 drive and the hydraulic of load move
Power input terminal connects, that is, two hydraulic oil pumps 10 high-pressure oil pipe converge after access hydraulic device distributor, Ge Gegao
Check valve 12 is respectively equipped on pressuring oil pipe.The check valve 12 is can only to export the non-return valve that cannot be flowed back, also referred to as check-valves.
When work, it can according to need and select motor 7 with actual conditions or internal combustion engine 8 is engine, drive oneself
Hydraulic oil pump 10 works, and exports high pressure oil.Since high-pressure oil pipe 11 is designed with check valve 12 above, so, high pressure oil cannot return
Stream, can only squeeze into load system by high-pressure oil pipe 11, in general, be exactly the distributor into hydraulic device, also referred to as manipulate
Device is operated by personnel, provides power for the movement of complete machine and the movement of digger blade.
Obviously, above-mentioned two sets of engines can independent operation, do not need to rotate simultaneously, thus power consumption is relatively low.This
Outside, this engine being installed in parallel is compared with concatenated engine, and lateral occupy-place is wider, and longitudinal space is shorter, is relatively suitble to
The design feature of existing excavator.
Second of embodiment: as shown in figure 3, leading between the power output shaft of internal combustion engine 8 and the power output shaft of motor 7
Transmission mechanism is crossed mutually to be driven.The effect of this structure type is the devices such as fan that diesel engine is driven in electric motor operation
It still is able to run well.Transmission mechanism described here is preferably driving wheel 14 and transmission belt 15, power output shaft and transmission
It is preferably provided with clutch 16 between wheel 14, to make the power output shaft of diesel engine be divided into two sections, in electric motor operation, diesel oil
The power output shaft of machine only has a Duan Yunzhuan, and bearing is avoided to operate.In diesel engine work, the power output shaft of motor is only
Some is rotated with it, and main body does not operate therewith.
Obviously, can be realized the purpose clutch be it is very much, Fig. 4 recommends a kind of centrifugal clutch 17.It can in figure
See, centrifugal clutch 17 is made of components such as driving shaft 18, centrifugal-block 20 and passive axle sleeves 19, and centrifugal-block 20 passes through tension spring
It is connected to the periphery of driving shaft 18, when driving shaft 18 does not turn, centrifugal-block 20 is attached to the periphery of driving shaft 18, with passive axle sleeve 19
Retention gap, at this point, passive axle sleeve 19 can be rotated individually.After rotation axis 18 rotates, effect of the centrifugal-block 20 in centrifugal force
Lower outer shifting, i.e., combined with passive axle sleeve 19, and passive axle sleeve 19 is driven to rotate together.When motor 7 works, motor is moved
Power output shaft drives passive axle sleeve, that is, driving wheel rotation as driving shaft rotation, drives the driving wheel of diesel engine to rotate, band
The devices operating such as dynamic fan, and the power output shaft of diesel engine does not rotate.When diesel engine work, the power output of diesel engine
Axis is rotated as driving shaft, and passive axle sleeve i.e. driving wheel is driven to rotate, and drives the rotation of the driving wheel of fan and motor, and
The power output shaft of motor does not rotate.
The third embodiment: as shown in figure 5, on the basis of second of embodiment, changing the form of clutch, uses
Freewheel clutch 21.Freewheel clutch 21 is the clutch of a kind of single-direction transmission, and there are many form, and what is enumerated in figure is a type
It is similar to the simple structure of bicycle freewheel: inner shaft 22 and 23 clearance fit of housing, inner shaft 22 is fitted with can by the control of spring 26
The pawl 25 slightly swung, 23 inner hole of housing are equipped with the ratchet 24 of multiple pointed tooths.When motor 7 works, the power of motor
Output shaft is rotated as inner shaft drives housing, that is, driving wheel rotation, drives the driving wheel of diesel engine to rotate, drives fan etc.
Device operating, and the power output shaft of diesel engine does not rotate.When diesel engine work, in the power output shaft conduct of diesel engine
Axis rotation drives housing i.e. driving wheel rotation, drives the rotation of the driving wheel of fan and motor, and the power of motor is defeated
Shaft does not rotate.
4th kind of embodiment: Fig. 6 introduces a kind of power machine structure, is improved on the basis of previous embodiment,
The hydraulic oil pump 10 is determined as duplex plunger pump 27, and the high-pressure oil pipe 11 of every suit duplex plunger pump 27 has two, separately there is one
13 connected tank 9 of oil return pipe.Duplex plunger pump more than 27 is equipped with pioneer pump 28, to use in booting.Since duplex plunger pump 27 is suitable for passing
Biggish power is passed, and high-efficient, is remarkably improved the task performance of excavator.
