Description
Technical field
The utility model belongs to articulated truck cooling device field, and in particular to a kind of articulated truck dynamical system
System intelligent control cooling system.
Background technology
Hinged type self-discharging automobile refers to the Transport Machinery with hinge joint and pendular ring between driver's cabin and car body.Articulator
Design philosophy originate from late 1960s Northern Europe, at that time the operating condition of bad weather and limited space there is an urgent need to
A kind of shovel soil transporting equipment between conventional rigid rear-unloading type carrier and scraper, this equipment are exactly present hinge
Connect formula dumper.Its purposes by initial gradual development and application of repairing the roads to mining industry, hydroelectric project, railway engineering and airport etc. no
In engineering project of the same trade, the type of transported material mainly has the transport of the loose unpacked materials such as soil, rock, sawdust and rubbish.
For being used for articulated truck liquid transmission unit, engine using in-line 6 cylinders or 8 cylinder type of V row, power from
200-400kw etc..Due to the road conditions very severe of operation, in order to improve the power performance of vehicle, transmission system is usual
Match the automatic gear-box with fluid torque-converter.Fluid torque-converter is the elasticity member between engine and gearbox train
Part, the hydrodynamic unit being made of pump impeller, turbine, guide wheel；Pump impeller is connected with engine flywheel, the gear shaft phase of turbine and gearbox
Even, the shell of turbine and gearbox is connected；Internal working fluid is gear box oil.
Under bending moment operating mode, fluid torque-converter can play the role of transmitting engine speed and torque, while generate big
Calorimetric amount, heating power generally transmit the 5%-25% of power at it, need to be equipped with corresponding cooling device so that gear box oil
In 90-95 DEG C of optimum working temperature.Under bending moment operating mode, engine intercooler, water jacket heat dissipation are in maximum heat dissipation capacity demand, hair
Motivation water pump inlet temperature is 93 DEG C, and leaving water temperature is 100 DEG C after each component of cooling engine.
If by engine radiating and torque-converters heat dissipation series design, only there are two types of selections.Selection one：Torque-converters is radiated
It is placed in water inflow of the engine end, meets the cooling of torque-converters and requires, but can lead to that water inflow of the engine resistance is big, inflow temperature is higher than
It is required it is required that being unsatisfactory for the cooling of engine；Selection two：Torque-converters is placed in engine water outlet end, because of engine outlet water temperature
It is 100 DEG C, then cannot reaches the cooling of torque-converters and require.Therefore power transmission common at present design uses double-radiator side
Case, engine radiator and gearbox radiator are mutual indepedent, and engine and gearbox have respective cooling water channel, can meet change
The cooling requirements of square operating mode.
Under operating mode of walking or drive slowly, the Retarder that articulated truck gearbox is equipped with enables so that vehicle safety is steady
Lower long slope.Retarder is to generate the device that damping production reaches retarded acting using agitation gear box oil, is converted kinetic energy into
The thermal energy of gear box oil, this partial heat energy are also required to cooling unit absorption.Under this operating mode, engine intercooler, water jacket heat dissipation
In minimum heat demand.Under normal conditions, fluid power jogging maximum power can reach or close to engine power rating, corresponding to dissipate
Hot device size is larger.
In current double-radiator scheme, only gearbox radiator participates in work, engine radiator under operating mode of walking or drive slowly
In idle state, significant wastage is generated.And double-radiator scheme weight is larger, occupied space causes difficult arrangement, it is of high cost,
Poor reliability.
That attempts to solve the problems, such as this has Chinese utility model patent CN200720046839：By gearbox cooling and one
The gearbox air-cooled radiator of small size is connected in series in engine radiating water route, can reduce the ruler of gearbox air-cooled radiator

Too low or heating is slow.TOT Transmission Oil Temperature is too low, and fluid is sticky, can cause insufficient lubrication and shift valve attonity, is opened in vehicle
In dynamic process, it is desirable that TOT Transmission Oil Temperature energy rapid increase.Two, the cooling water in gearbox cooling circuit carries water by engine
Pump driving, can cause cooling circuit resistance excessive.
Technical solutions all at present all relies on the flow direction that thermostat adjusts water route, realizes different cycles, passes through wind
Fan clutch adjusts rotation speed of the fan and reaches energy saving, and element complexity is unreliable, not smart enoughization.
