第1节四驱汽车布置方式前纵置发动机四驱车型现在的前纵置发动机四驱车型,都是基于两类车型改造而来的:一是基于前纵置发动机后轮驱动车型。从布局上可明显看出,这种前置发动机的动力输出到变速器后,直接通过传动轴将动力传递到后轮。为了改造成四驱车型,就在变速器与传动轴的连接处,加上一个分动器,再通过一根前传动轴将动力引取到前驱动轴(上图)。代表车型:宝马、 Section 1 Four-wheel drive car arrangement Front longitudinal engine four-wheel drive model Now the longitudinal longitudinal four-wheel drive vehicle models are based on two types of models from the transformation: First, based on the front longitudinal rear-engine engine models. As is evident from the layout, the power of this front engine is output to the transmission and transmitted directly to the rear wheels through the drive shaft. In order to retrofit into a 4WD model, a splitter is added to the connection of the transmission to the drive shaft, which is then drawn to the front drive shaft via a front drive shaft (pictured above). Representative models: BMW,
