Engine end face pulley arrangement structure

Abstract

An engine end face pulley arrangement structure is characterized in that: a crank pulley, an air condition compressor pulley, a first idle pulley, a generator pulley and a water pump pulley are arranged on the same end face of an engine body; a second idle pulley is arranged beside the first idle pulley; the first idle pulley, the second idle pulley, the crank pulley, the air condition compressor pulley, the generator pulley and the water pump pulley are arranged in a same vertical plane and are connected through a same belt; and the first idle pulley and the second idle pulley are positioned in a quadrilateral area bounded by the crank pulley, the air condition compressor pulley, the generator pulley and the water pump pulley. In the engine end face pulley arrangement structure provided by the invention, all pulleys on the same end face of the engine body are arranged in the same vertical plane and are connected through the same belt, so that lateral length dimension of a large-displacement engine is effectively reduced, and the large-displacement engine and an automatic speed changer can be arranged in a cabin of a small-displacement car on the premise that a cabin frame of the small-displacement car is not changed.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to the arrangement structure of the pulley on the end surface of the car engine. Background technique [0002] At present, small-displacement cars are generally equipped with a small-displacement engine in the cabin and equipped with a manual transmission. Although it can reduce the production cost of the vehicle, it has disadvantages such as weak power, complicated operation, and large shifting impact. Limited by the large lateral length of the large-displacement engine, a small-displacement car cannot be installed with a large-displacement engine and an automatic transmission within the original frame. The reason for the large transverse length of the large-displacement engine is mainly that the arrangement of the pulleys on the same end face of the engine body is unreasonable. Such as Figure 4 As shown, the crankshaft pulley 2, the air conditioner compressor pul...

AI Technical Summary

Problems solved by technology

Since the crankshaft pulley 2 is covered with two four-groove belts 7, the distance between the two end faces of the crankshaft pulley 2 is large, and the crankshaft pulley 2, the air conditioner compressor pulley 3, the first idler pulley 4, the generator pulley 5 and the water pump The pulleys 6 are not in the same vertical plane, resulting in a larger lateral length dimension of the engine

At the same time, the pulleys on the end face of the engine are connected by two belts, which is not only complicated, laborious and costly to assemble, but also to adjust the tension of the belts requires adjusting the position of the first idler pulley and the position of the generator pulley. The operation is very cumbersome
