Problems solved by technology
[0003] In the prior art, there are mainly two ways to design the front-end gear train of the engine. One is to assemble the crankshaft pulley on the shock absorber, so that the crankshaft pulley is used as the driving wheel to drive the above components; the length of the front-end gear train of the engine with this structure is longer , resulting in a larger overall size of the engine, which is not conducive to matching the engine
Another type, in order to reduce the overall size of the engine, the shock absorber and the crankshaft pulley are integrated, so that the shock absorber and the crankshaft pulley are integrated to drive each component; Due to the large shock absorber, after being directly connected to the pulley of the air conditioner through the belt, the speed ratio of the air conditioner is relatively large. The speed ratio of the current air conditioner is usually above 1.6, and the reliability of the air conditioner is poor and the failure rate is high.

The invention discloses a front-end gear train of an engine, which includes a shock absorber, a generator, an air conditioner, a water pump, and a fan bracket. The shock absorber drives the generator, the water pump, and the fan bracket through a belt connection. and the air conditioner; the integrated pulley of the shock absorber forms an integrated pulley of the shock absorber, and a crankshaft pulley is installed at the coaxial position of the integrated pulley of the shock absorber; the front-end wheel train of the engine is divided into a first wheel train and a second wheel train Two wheel trains, the first wheel train includes the shock absorber integrated pulley, the generator driven by the shock absorber integrated pulley, the air conditioner, the second wheel train includes the crankshaft pulley, The water pump driven by the crank pulley, the fan bracket. Through its structural optimization design, it can not only ensure a compact structure, shorten the length of the engine, but also increase its supporting range, improve reliability and reduce costs.
Description
technical field [0001] The invention relates to the technical field of engines, in particular to an engine front wheel train. Background technique [0002] The engine front-end wheel train provides power for vehicle auxiliary systems, including generators whose speed ratios are not easy to change, air conditioners, water pumps and fan brackets whose speed ratios may need to be changed during application. The reducer is connected to drive various components through pulleys and belts. [0003] In the prior art, there are mainly two ways to design the front-end gear train of the engine. One is to assemble the crankshaft pulley on the shock absorber, so that the crankshaft pulley is used as the driving wheel to drive the above components; the length of the front-end gear train of the engine with this structure is longer , causing the overall size of the engine to be larger, which is not conducive to the matching of the engine. Another type, in order to reduce the overall size ...
