Description
Technical field
The invention belongs to refrigeration machine field, and in particular to a kind of transport refrigeration unit using electromagnetic clutch technology.
Background technology
Refrigerator car refers to the closed transport van for transport frozen or fresh-keeping goods, refrigerator car refrigeration according to
By the refrigerating plant equipped with refrigeration unit and the heat-insulated railway carriage or compartment of polyurethane.Refrigerating machine of refrigerated truck group is provided in a steady stream not for refrigerator car counter
The visual plant of disconnected " cold ", the forward top of counter is typically all installed at, there is the profile as air-conditioning, but than the air-conditioning of same volume
With stronger refrigerating capacity.
Refrigerator car refrigeration compressor uses engine driving when vehicle travels, and when refrigerator car is stopped, vehicle stall can
Continue to drive refrigeration compressor with the motor by external power supply.Current transport refrigeration unit most on the market all uses
Friction type clutch, to be compressed the switching in mechanomotive force source, and slip clutch is due to generating heat at work, and produces mill
Damage, works long hours and is easily damaged, and fault rate is high, increases maintenance cost and energy.And broken down during vehicle traveling, influence cold
But effect, easily causes the corruption such as the fresh of refrigeration, medicine or failure, and loss is serious.
The content of the invention
For the above-mentioned deficiency present in prior art, the technical problem to be solved in the present invention is to provide one kind to use electromagnetism
The transport refrigeration unit of clutch technology, it is reduced clutch system fault rate, improved by the electromagnetic clutch technology independently researched and developed
Refrigeration unit stability.The present invention adopts the following technical scheme that：A kind of transport refrigeration unit using electromagnetic clutch technology, including
Engine, refrigeration compressor, motor, electromagnetic clutch.Engine and motor are located at refrigeration compressor both sides, output torque
The outer side band wheel for driving electromagnetic clutch by engine belt wheel rotates.Electromagnetic clutch is by outside belt wheel and inner side belt wheel group
Into inner side belt wheel is connected with refrigeration compressor piston；Motor external power supply, converts electrical energy into mechanical energy, output torque according to
The inner band wheel for driving electromagnetic clutch by motor pulley rotates, driving refrigeration compressor operating.Electromagnetic clutch connection electricity
Road plate, circuit board controls the switch of electromagnetic clutch, and during electromagnetic clutch energization work, electromagnetic coil is by outside belt wheel and inner band
Wheel is attached together, gas-engine-driven chillerses compressor operation.
Further, belt transmission, motor pulley are passed through between engine belt wheel and the outside belt wheel of electromagnetic clutch
Pass through belt transmission between the inner side belt wheel of electromagnetic clutch.
Further, the magnetic grade of the electromagnetic coil of electromagnetic clutch determines according to the difference of refrigerant compression acc power.
Beneficial effect：
The present invention is different from traditional clutch mode, and friction clutch operation principle is that slip clutch is arranged on engine
In output end, it is connected on the inside of clutch with engine shaft, compressor piston is connected with transmission parts, and transmission parts are to be fixed as
Two belt wheels of one, a belt wheel are connected by belt with motor, and another is connected with belt wheel on the outside of engine.Engine
Rotating speed, which improves, after startup produces centrifugal force, clutch inboard friction piece and outside belt wheel friction tensioner, drives driving compressor, electricity
Motivation can drive compressor operation when operating, and also drive the idle running of engine outer side band wheel.
Friction clutch friction plate is easily worn, and clutch efficiency is influenceed after abrasion, causes fault rate to improve, and need centrifugal force
Bringing up to specified rotating speed just drives refrigeration compressor to operate.It is safe and the present invention uses electromagnetic clutch, add clutch
The device life-span, and start quick, clutch efficiency high.
