Twin-air-conditioner wheel system structure of diesel engine

Abstract

The invention discloses a twin-air-conditioner wheel system structure of a diesel engine. A torsional damper belt wheel, an electric generator belt wheel and a water pump belt wheel are wound with a belt to form a first wheel system. A first air conditioner tension wheel, a first air conditioner compressor belt wheel, the electric generator belt wheel and the torsional damper belt wheel are wound with a belt to form a second wheel system. The torsional damper belt wheel, a second air conditioner compressor belt wheel and a second air conditioner tension wheel are wound with a belt to form a third wheel system. The three wheel systems are combined together by the torsional damper belt wheel. The first wheel system contains a second belt slot of the torsional damper belt wheel and a first belt slot of the electric generator belt wheel; the second wheel system contains a first belt slot of the torsional damper belt wheel and a second belt slot of the electric generator belt wheel; the third wheel system contains a third belt slot of the torsional damper belt wheel. Two air compressor wheel systems are used for refrigeration of a cab and a refrigerator car correspondingly and operate independently. The space layout is reasonable and compact, maintenance is facilitated, and the spare space of the diesel engine is utilized scientifically and reasonably.

Description

technical field [0001] The invention belongs to the diesel engine structure technology, and in particular relates to a double air-conditioning gear train structure used in the diesel engine. Background technique [0002] With the technological progress of the automobile manufacturing industry, the types of commercial vehicles are increasing according to the needs of different purposes. In order to achieve the purpose of keeping food fresh during long-distance transportation, the production of refrigerated special vehicles has become an important market. From the perspective of the safety of food preservation, frozen and refrigerated foods must be safely transported under the specified temperature. Because of this, the requirements for the performance or function of refrigerated special vehicles suitable for medium and long-distance transportation of cold and fresh food are also increasing. Due to seasonal differences in transportation, when the ambient temperature is high, ...

AI Technical Summary

Problems solved by technology

It is not difficult to add a set of compressors for air conditioning on the ground, but it is not easy for the interior assembly (engine) space of the car

The increase of engine accessory equipment will inevitably lead to an increase in the peripheral volume, but the space for the matching installation of the engine and the vehicle is limited

Moreover, the dual air-conditioning gear train structure of diesel engine is relatively complicated at present, and the prior art structure is that the second air-conditioning compressor is installed on the engine cylinder head by a support

In this way, the height or width of the diesel engine body is increased; and a single belt is used to drive multiple pulleys, and the reliability of its work cannot be guaranteed during operation.
