Abstract

The invention discloses an engine front end structure. The engine front end structure is provided with a crankshaft belt wheel, a water pump, a fan shaft part and an air conditioner compressor. The water pump and the fan shaft part are arranged in a spaced manner, the crankshaft belt wheel, a driving wheel of the fan shaft part and a driving wheel of the water pump are connected through a belt, and the driving wheel of the fan shaft part is connected with a belt wheel of the air conditioner compressor through a belt. The manner that the water pump is laterally arranged, and the water pump and the fan are arranged in a spaced manner is adopted, the fan shaft part drives a fan and the air conditioner compressor, power loads of the water pump are greatly reduced, the failure rate of the water pump is reduced, and meanwhile the method of increasing the diameter of the fan is adopted to reduce the noise of the fan. The arrangement distance of a connecting pipeline between the water pump and an engine oil cooler is further shortened, the arrangement distance of a connecting pipeline between a radiator and the water pump is also shortened, the pipeline arrangement cost of a whole machine is reduced, and meanwhile the water inlet resistance of a whole machine cooling system is reduced.

Description

technical field [0001] The invention relates to the field of engines, in particular to an engine front end structure. Background technique [0002] In the existing integrated water pump layout design, the water pump is generally arranged in the middle of the front end of the engine (in the width direction), and a fan (500mm-540mm in diameter) needs to be installed at the front end of the water pump most of the time, and in the layout scheme of the multi-layer gear train, The water pump needs to drive accessories such as motors or air conditioners, which leads to an increase in the power load of the water pump, resulting in an increase in the failure rate of the water pump, and the pipeline connection line of the water pump is long and the water resistance is large. In addition, in order to reduce the noise of the fan, the noise of the fan needs to be reduced by reducing the speed of the fan or increasing the diameter of the fan. However, since the speed of the fan is consist...
