Description
Technical field
The utility model relates to a kind of power drive, relates in particular to the power transfer device of the changeable type of drive that a kind of special purpose vehicle uses.
Background technology
The available dynamic driving device generally adopts gear and axle that power is directly transmitted with one to one ratio, when being applied to special vehicle, just showed this power drive more drawback, for example: sweeping machine, sweeping machine are a kind of equipment that structure is the most complicated in the environmental sanitation special vehicle, application is maximum.Sweeping machine in the market generally is to reequip with car chassis, and it is the engine installation of assistant engine that a cover diesel engine normally is installed on original chassis again, as dust absorption fan, sweep the power of device such as dish.Owing to use dual dynamic, energy-output ratio is big, and noise is big, make chaufeur need look after two place's power during operation, be very easy to fatigue, and use mechanically operated blower fan, driving engine is worked under the high speed low torque condition, and the life-span is short, the fault rate height, dynamic efficiency is also low, original sustainer, main engine will slow running under the speed per hour below 6 kilometers, is under the burning abnormal state, and rotary speed unstabilization is fixed, thrust deficiency, exhaust emission are also bigger.If can directly utilize former automotive engine is whole power, when cleaning works be that type of drive promotes clearing apparatus with the hydraulic-driven, recovering the direct driving force type of drive when off working state can run at high speed, to overcome original shortcoming, the each several part power configuration to optimum regime, will be economized the energy, reduce and pollute, reducing noise, make driving work more convenient comfortable again, is a kind of excellent settling mode.At present domestic do not have this design, though the single-engined sweeping machine design of minority is abroad arranged, all is the large-tonnage chassis, complex structure, and price is high, is not applicable to the kind of the short wheelbase chassis that 3 tonnages are following.As environmental protection; the equipment of environmental health operation; it is big that itself just is in the exhaust emission amount; waste energy; the state that noise is high; be unsatisfactory; and state locates the sort of complex structure; the large-scale monomotor sweeping machine that price is high; do not meet urban highway condition and the relatively operating cost requirement of Ji again; this up-to-date technology is positioned the condition of down town road just; satisfy low-cost demand again; hydraulically powered sweeping machine can be fully designs according to the technical characterictic of cleaning work; aspect cleaning work, be more perfect, still, because hydraulic efficiency is lower; promptly satisfy the high speed requirement of walking needs simultaneously, the hydraulic efficiency pressure system that satisfies the high pulling torque requirement of cleaning needs again is very expensive.
The technical problems to be solved in the utility model is: the power transfer device that a kind of changeable type of drive is provided, make the original driving engine of vehicle except the stable takeoff output that a same rate can be provided, another low-speed big stepless change power also can be provided.
The utility model is achieved in that the power transfer device of changeable type of drive, comprise one with the outlet bonded assembly input shaft of engine mission, one with the import bonded assembly output shaft of rear-axle differential, input shaft and output shaft join by gear, and it also is provided with: a sundstrand pump input shaft that joins with the import of union variable oil pump; The one motor input shaft that joins with the mouth of HM Hydraulic Motor; One can cut off input shaft and the interaxle through-coupling of output, make input shaft and sundstrand pump input shaft pass through direct geared, and motor input shaft and output shaft be by the shifter of direct geared, is connected by hydrostatic drive between the outlet of union variable oil pump and the input end of HM Hydraulic Motor.
This structure can provide multiple spot different flow hydraulic power transmission function, more traditional power takeoff can provide the hydraulic efficiency power unit of more diversification, after sweeping machine adopts transfer device of the present utility model, the advantage that both can keep the high-speed and high-efficiency transmission of automobile traveling, all-hydraulic transmission engineering factor when satisfying cleaning again, cost is low and effect is identical with the low-speed big power hydraulic system.Utilize one near the homemade twin-engined sweeping machines on former 2 tons of Isuzu Motors short base chassis of scrapping, through repacking, after front and back were loaded onto power transfer device of the present utility model respectively, every index all met or exceeded brand-new sweeping machine.Switch under the transfer state, when the driving engine mouth weighs fast 1440rpm (speed per hour that is equivalent to 40km), dust suction degree of vacuum can surpass 350 millimeter water column, in the test in four months average fuel consumption less than former new car oil consumption 70%, noise reduces near 10db than original standard.Except sweeping machine, road cleaning vehicle, cut sled etc. and when work, both needed the low speed walking, need stablize the street rod of auxiliary power source driving equipment again, can use this transfer device.
