Accessory wheel system for automobile engine and automobile engine with accessory wheel system

Abstract

The invention discloses an accessory wheel system for an automobile engine and an automobile engine with the accessory wheel system. The accessory wheel system comprises a crankshaft damping belt wheel, an air conditioning compressor belt wheel, a power generator belt wheel, a belt and a hydraulic automatic tensioner, the crankshaft damping belt wheel is connected with a crankshaft of the automobile engine to rotate along with the engine crankshaft, the air conditioning compressor belt wheel, the power generator belt wheel and the crankshaft damping belt wheel are positioned in a same plane, the belt is sleeved on the crankshaft damping belt wheel, the air conditioning compressor belt wheel and the power generator belt wheel to enable the air conditioning compressor belt wheel and the power generator belt wheel to rotate along with the crankshaft damping belt wheel, a belt wheel of the hydraulic automatic tensioner abuts against the belt to apply a preset tensioning force to the belt, and the crankshaft damping belt wheel, the air conditioning compressor belt wheel, the power generator belt wheel and the hydraulic automatic tensioner are positioned in a same plane. According to the accessory wheel system for the automobile engine, overall compactness and miniaturization of the engine are realized to adapt to a narrow arrangement space of an engine room of a whole automobile.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an accessory wheel train for an automobile engine and an automobile engine with the same. Background technique [0002] The gear train arrangement of the front-end accessories of the automobile engine is relatively complicated, and the quality of the gear train design will directly affect the performance and reliability of the engine, and then affect the technical indicators of the whole machine and vehicle. [0003] With the development of the times, the design of contemporary automobiles tends to be technical and multi-functional. More and more new technologies are applied to the automotive field. The small size makes the car engine design tend to be compact and miniaturized. The arrangement level of the front end accessory gear train of the engine greatly affects the compactness and overall size of the overall arrangement of the engine. [0004] The front-end accessory w...

AI Technical Summary

Problems solved by technology

Its shortcoming is that the layout of the mechanical automatic tensioner requires a large axial space. If the tensioner is arranged between the damping pulley and the alternator, the position of the alternator needs to be moved to the outside accordingly, and the cylinder There is a certain space between the body to arrange the tensioner, which will cause the engine to be less compact and increase the overall size, which exceeds the reserved space for the engine in the engine room of the vehicle, and cannot meet the requirements for the layout of the vehicle.
