Detailed description of the invention
Below in conjunction with drawings and Examples, the structure of the present invention is further described. The double; two air-conditioning wheel train structure of diesel engine, torsional vibration damper belt wheel is provided with four troughs of belt, electromotor belt wheel is provided with three troughs of belt, and Water-pump belt wheel is provided with two troughs of belt, and its structure composition is: constituted the first train by torsional vibration damper belt wheel 1, electromotor belt wheel 2 and Water-pump belt wheel 3 by the first belt 4 winding; The second train is constituted by the second belt 7 winding by first air-conditioning expansion tightening wheel the 5, first air conditioner compressor belt pulley 6, generator pulley and torsional vibration damper belt wheel; Constituted third round system by torsional vibration damper belt wheel, the second air conditioner compressor belt pulley 8 and the second air-conditioning expansion tightening wheel 9 by the 3rd belt 10 winding, by torsional vibration damper belt wheel, first, second, and third train is combined. From outside to inside, the first train occupies the second trough of belt of torsional vibration damper belt wheel and the first trough of belt of electromotor belt wheel; Second train occupies the first trough of belt of torsional vibration damper belt wheel and the second trough of belt of electromotor belt wheel; Third round system occupies the 3rd trough of belt of torsional vibration damper belt wheel.
The concrete installation site of each belt wheel is: the first air conditioner compressor belt pulley is positioned at the top of electromotor belt wheel; Second air conditioner compressor belt pulley is positioned at the left side of torsional vibration damper belt wheel; First air-conditioning expansion tightening wheel is positioned at the right side of Water-pump belt wheel; Second air-conditioning expansion tightening wheel is between the second air conditioner compressor belt pulley and torsional vibration damper belt wheel; Electromotor belt wheel is positioned at the left side of Water-pump belt wheel.
Its mounting structure is: the first compressor of air conditioner is fixed on the first air compressor support 11, and the first air condition compressor bracket is fixed on diesel engine cylinder cover 12; First air-conditioning expansion tightening wheel is fixed on the first expansion tightening wheel support 13, and the first expansion tightening wheel support is fixed on diesel-engine body 14; Second compressor of air conditioner is fixed on the second air compressor support 15, and the second air compressor support is arranged on diesel-engine body; Second air-conditioning expansion tightening wheel is arranged on the second expansion tightening wheel support 16, and the second expansion tightening wheel support is fixed on the front end installing plate 17 of described diesel engine.
Torsional vibration damper belt pulley is by described 3rd belt drives the second air conditioner compressor belt pulley and the second air-conditioning expansion tightening wheel. Because the driving force needed for the first train is relatively larger, and reliability requirement is also higher, so the first train adopts two belts torsional vibration damper belt wheel, electromotor belt wheel and Water-pump belt wheel to be intertwined.
Torsional vibration damper belt wheel passes through the first belt drives generator pulley and Water-pump belt wheel, then torsional vibration damper belt wheel passes through second belt drives the first air conditioner compressor belt pulley, the first air-conditioning expansion tightening wheel, the second air conditioner compressor belt pulley, the second air-conditioning expansion tightening wheel, and is positioned at the 3rd belt of the 3rd trough of belt. This torsional vibration damper belt wheel passes through the 3rd belt drives the second air conditioner compressor belt pulley and the second air-conditioning expansion tightening wheel.
Torsional vibration damper (belt wheel) and engine crankshaft are connected to become the drivewheel in this train, and belt wheel turns clockwise and drives whole train to run. Second air-conditioning expansion tightening wheel is used for regulating the tension force of the 3rd belt, and the second air-conditioning expansion tightening wheel is located at the inner side of the 3rd belt, regulates device and is arranged in outside, and outside tensioner (is beneficial for disassembly and assembly and keeps in repair). This structure arranges and makes two compressor of air conditioner trains is two completely self-contained trains, and the first compressor of air conditioner train provides refrigeration for driver's cabin, and the second compressor of air conditioner train provides refrigeration for car load cold closet. The work of compressor of air conditioner is separate, works each other unaffected, meets city cold storage logistics car and car load driver's cabin and cold closet provide the demand of independent cooling.
