Diesel engine front end power output device

Abstract

The invention discloses a diesel engine front end power output device, and belongs to the technical field of power output devices. The diesel engine front end power output device comprises a first wheel train driving a generator and an air conditioner compressor to conduct transmission, a second wheel train independently driving a fan to conduct transmission and a fan transmission device arrangedabove a crankshaft. According to the diesel engine front end power output device, power generated by an engine can be stably and effectively output, the fan is independently driven by the second wheeltrain, the precision requirements for the parallelism and the coplanarity of the whole wheel trains can be lowered, the fan can operate more stably, the power output problem of the diesel engine front end wheel trains is solved, the space requirement and the power requirement of a whole vehicle are further met, the occupied space is small, and the requirement of the whole vehicle is met; the transmission power is large, and noise is low; and using and maintaining are easy, the structure is simple and firm, performance is stable, and the requirement of a user for high-power auxiliary power ismet.

Description

technical field [0001] The invention relates to the technical field of power output devices, in particular to a front-end power output device of a diesel engine. Background technique [0002] As people's demand for vehicles is getting higher and higher, the vehicle's demand for auxiliary power delivered by the engine is increasing. In order to meet the task requirements of a certain type of vehicle, the problems and solutions that need to be solved are as follows: [0003] 1. Optimization of the installation position of the generator: The demand for power generation of the generator by the vehicle is increasing, but with the increase of the power generation of the generator, it is necessary to increase the volume of the generator, so that the horizontal size of the engine increases, which will cause the engine to Reduced overall adaptability; [0004] 2. Optimization of the transmission mode: the original transmission is in the form of a V-belt, and each pulley is driven by...
