Specific embodiment
The total design of the present invention is: the internal combustion engine that excavator is equipped with and motor are installed in parallel.The concrete knot of said apparatus
Structure can have multiple, all should belong to equivalent frame for movement.Introduce five kinds of embodiments below in conjunction with the accompanying drawings:
The first embodiment: Fig. 1 describes a kind of excavator, is provided with frame 1, road wheel 2, digger blade 3, digging arm 4, driver's cabin
5, allotter 6, motor 7, internal combustion engine 8, fuel tank 9.The road wheel 2 of in figure is Athey wheel or circle wheel.Excavator dynamic
Power machine has and motor 7 and internal combustion engine 8, adopts diesel engine internal combustion engine more.Visible in conjunction with Fig. 2: motor 7 and internal combustion engine 8 are respectively
Drive respective hydraulic oil pump 10, hydraulic oil pump 10 is designed with high-pressure oil pipe 11 and oil return pipe 13, the hydraulic oil pump 10 of internal combustion engine 8
The outfan of high-pressure oil pipe 11 of hydraulic oil pump 10 that drives with motor 7 of high-pressure oil pipe 11 and load hydraulic power input
End connects, that is, the high-pressure oil pipe of two hydraulic oil pumps 10 converge after access hydraulic means allotter, each high-pressure oil pipe
On be respectively equipped with check valve 12.Described check valve 12 is to export the non-return valve that can not flow back, also referred to as check-valves.
During work, motor 7 or internal combustion engine 8 can be selected with practical situation to be as needed engine, drive oneself
Hydraulic oil pump 10 works, and exports hydraulic oil.Because high-pressure oil pipe 11 is designed with check valve 12 above, so, hydraulic oil can not return
Stream, can only squeeze into load system by high-pressure oil pipe 11, in general it is simply that entering the allotter of hydraulic means, also referred to as manipulate
Device, by human users, the action of the movement for whole machine and digger blade provides power.
Obviously, above-mentioned two sets of engines can independent operation it is not necessary to rotate simultaneously, thus power consumption is than relatively low.This
Outward, compared with the engine of series connection, horizontal occupy-place is wider, and longitudinal space is shorter for this engine being installed in parallel, and is relatively suitable for
The construction featuress of existing excavator.
Second embodiment: as shown in figure 3, logical between the power output shaft of the power output shaft of internal combustion engine 8 and motor 7
Cross the transmission of drive mechanism phase.The effect of this version is in electric motor operation, the device such as fan that diesel engine is driven
Remain able to run well.Drive mechanism described here is preferably drive 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 one section of operating, and avoids bearing to operate.When diesel engine works, the power output shaft of motor is only
Some concomitant rotation, its main body does not operate therewith.
Obviously, it is a lot of for being capable of described purpose clutch, and Fig. 4 recommends a kind of centrifugal clutch 17.In figure can
See, centrifugal clutch 17 is made up of parts such as driving shaft 18, centrifugal-block 19 and passive axle sleeves 20, and centrifugal-block 19 passes through extension spring
It is connected to the periphery of driving shaft 18, when driving shaft 18 does not turn, centrifugal-block 19 is attached to the periphery of driving shaft 18, with passive axle sleeve 20
Retention gap, now, passive axle sleeve 18 can individually rotate.After rotary shaft 18 rotates, centrifugal-block 19 is in the effect of centrifugal force
Lower outer shifting, is covered with driven axle and combines, and drive passive axle sleeve 20 to rotate together.When motor 7 works, the power of motor
Output shaft rotates as driving shaft and drives driven axle set, that is, drive rotates, and drives the drive of diesel engine to rotate, drives
The devices such as fan operate, and the power output shaft of diesel engine does not rotate.When diesel engine works, the power output shaft of diesel engine
Rotate as driving shaft, drive passive axle sleeve i.e. drive to rotate, drive fan and the drive of motor to rotate, and electric
The power output shaft of motivation does not rotate.
The third embodiment: as shown in figure 5, on the basis of second embodiment, changing the form of clutch, adopt
Freewheel clutch 21.Freewheel clutch 21 is the clutch of a class single-direction transmission, and its form is a lot, and what in figure enumerated is a species
It is similar to the simple structure of bicycle freewheel: interior axle 22 and the cooperation of overcoat 23 gap, interior axle 22 is fitted with that controlled by spring 26 can
The ratchet 25 slightly swinging, overcoat 23 endoporus is provided with the ratchet 24 of multiple pointed tooths.When motor 7 works, the power of motor
Output shaft rotates as interior axle and drives overcoat, that is, drive rotates, and drives the drive of diesel engine to rotate, drives fan etc.
Device operates, and the power output shaft of diesel engine does not rotate.When diesel engine works, the power output shaft of diesel engine is as interior
Axle rotates, and drives overcoat i.e. drive to rotate, and drives fan and the drive of motor to rotate, 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 to improve on the basis of previous embodiment,
Described hydraulic oil pump 10 is defined as duplex plunger pump 27, and the high-pressure oil pipe 11 of every suit duplex plunger pump 27 all has two, separately has one
Oil return pipe 13 connected tank 9.Duplex plunger pump more than 27 is provided with pioneer pump 28, to use in start.Because duplex plunger pump 27 is suitable to pass
Pass larger power, and efficiency high, it is remarkably improved the task performance of excavator.
