Description
Technical field
The invention belongs to special-purpose vehicle art drive systems fields, more particularly, to a kind of mould for monomotor special-purpose vehicle
The energy saving and environment friendly power taking transfer case of blockization.
Background technique
With the continuous improvement of social civilization level and productivity level, the mechanization degree of all kinds of production operations requires to get over
Come higher, the value volume and range of product for having expedited the emergence of the special purpose vehicle with motor-driven work capacity surges.Special purpose vehicle is in addition to entering operation
Place needs except driving dynamics, and apparatus for work is also required to driving force.Wherein required for a variety of special purpose vehicle apparatus for work
Power it is very big, and generally require multichannel power while driving multiple apparatus for work.Technical solution common at present is special
With installing one on chassis again dedicated for the assistant engine for driving apparatus for work, i.e., there are two engine, chassis for vehicle tool
Engine provides power for vehicle traveling, and assistant engine provides power for apparatus for work.This power configuration scheme bring is asked
Topic is, in special-purpose vehicle operation process, engine in situ is in dead halt state or in low speed small power Operation Conditions.Before
Person causes the idle wasting of resources generated of big time of engine in situ, and improves vehicle manufacturing cost, and the latter due to
Fuel combustion efficiency is low, and output power is small so that the specific fuel consumption of engine in situ increases, discharge index decline, cause operation at
This raising and increasing environmental pollution.More seriously, the secondary hair including external many twin-engined special purpose vehicles domestic at present
The discharge index of motivation is generally lower than the discharge index of engine in situ, so, assistant engine discharges useless in operation process
Gas is more serious to the pollution of environment.So there are serious shortcomings for the twin-engined power configuration schemes of special-purpose vehicle.
With the continuous sharp increase of special purpose vehicle quantity, one kind can satisfy different special-purpose vehicle power demands, reduction system is matched
It is set to economic benefit caused by sheet, energy-saving and environment-friendly power scheme and social benefit will be huge.Therefore, have in the world
Multiple countries put into a large amount of manpower and material resources research monomotor special-purpose vehicle dynamical systems and its key equipment, and achieve one
A little achievements.In as described in " for the mileage recording device with transfer case taking-force engineering vehicle " (ZL 200920002716.X)
Journey recording device is judged whether by means of control signal using original sensor indirectly as an independent add-on device
Signal carries out speed calculating and mileage is cumulative.Obviously, this judgement is extra useless for the special-purpose vehicle of stationary deployment, and
Indirect signal is judged since and, brings the probability of erroneous judgement and misjudgement very high.For another example " high-pressure water mist fire truck power taking point
Dynamic device " power taking transfer device described in (201110345985.8) is a kind of dedicated particular vehicle, without passing through module
It combines and the pervasive characteristic with multiple functions.A kind of for another example " special vehicle clutch transfer case " (ZL
201620397820.3) the power taking transfer case described in, it is same not have through block combiner with multiple functions, satisfaction difference
The pervasive characteristic of special-purpose vehicle power demand does not have self-lubricating, energy conservation and environmental protection characteristic yet.
As it can be seen that have been known it is similar in the prior art, the equal existing defects of structure, function, performance not exclusively meet special
With vehicle power demand and the requirement of raising centralized control and vehicle comprehensive performance.Therefore, a kind of that there is Modular Flexible to combine function
Energy, energy conservation and environmental protection, function admirable general power taking transfer case be improve special-purpose vehicle overall performance level core component.
