A kind of automobile engine front end accessory wheel train system

Abstract

A front-end accessory wheel train system of an automobile engine comprises a crankshaft pulley with double-layer pulleys, an automatic tensioner pulley, an alternator pulley, an idler pulley, a water pump pulley, an air conditioner compressor pulley and two V-belts. The system is divided into two layers of accessory gear trains; the first layer is connected by the first V-ribbed belt clockwise to the crankshaft pulley, the first layer of the crankshaft pulley, the automatic tensioner, the alternator pulley, the idler pulley and the water pump pulley. Composition; the second layer is formed by connecting the second layer of the crankshaft pulley and the pulley of the air conditioner compressor sequentially by the second V-ribbed belt along the clockwise direction of the crankshaft pulley. Also, the alternator pulley is on the intake manifold side, and the water pump pulley is on the exhaust manifold side. The invention uses the automatic tensioning wheel and the elastic belt to solve the problems that the V-ribbed belt is easy to loosen when the V-ribbed belt is extended during the after-sales use of the front-end accessory wheel system of the engine, resulting in abnormal slipping noise and wear, and at the same time, it also takes into account the switching of the whole vehicle The air conditioner compressor is convenient and fast, and at the same time, it also considers the beauty of the engine and avoids the heat damage of the generator.

Description

technical field [0001] The invention relates to an automobile engine, and more specifically relates to an automobile engine front end accessory wheel train system. Background technique [0002] The transmission belt of the front-end accessory wheel system of the conventional automobile is an ordinary V-ribbed belt, and a manual tensioner or an adjustment bracket is added to tension the belt. The disadvantage is that the engine front-end accessory wheel system will , After the V-belt is extended, it is easy to loosen the belt, resulting in abnormal slippage and wear, which will affect the comfort of the car. [0003] At present, air-conditioning compressors have been used in a large area. The air-conditioning compressors provide cooling and heating capabilities for the vehicle's air-conditioning. However, in some areas where the temperature is suitable, and to reduce the cost of the vehicle, the air-conditioning compressor can be removed from the vehicle. , while the engine ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a front-end accessory wheel system of an automobile engine. When the automatic tensioner and elastic belt are used to solve the after-sales use process of the engine front-end accessory wheel system, the V-ribbed belt is easy to loosen the belt after being extended, resulting in slippage. In addition to problems such as abnormal noise and wear, it also takes into account the convenience and speed of switching the air-conditioning compressor of the whole vehicle, and also considers the beauty of the engine and avoiding the heat damage of the generator
