Problems solved by technology

At the same time, due to the different layout space and requirements of various market segments (forklifts, tractors, harvesters), the traditional front-end wheel train structure cannot meet the needs of each market segment at the same time, and different front-end wheel trains and special parts need to be designed
Traditional off-road diesel engine peripheral parts are scattered, which not only increases the size of the diesel engine, but also leads to too small wrap angle design of the front wheel train, often causing slippage
[0003] In addition, the coaxial arrangement of the water pump and the fan of the traditional non-road diesel engine will not only affect the heat dissipation of the diesel engine, but also have the following problems:
[0004] 1. The fan is installed on the water pump, the height is fixed and not adjustable

Abstract

The invention discloses a front end wheel train structure for an off-road diesel engine. The front end wheel train structure comprises a water pump cushion plate, a water pump driving wheel, a fan driving wheel, an automatic tensioning wheel, a crankshaft shock absorber driving wheel, a power generator driving wheel, an idle wheel and a transmission belt, wherein the water pump cushion plate is installed on a cylinder body and a cylinder cover through bolts, and an air conditioner is installed on the water pump cushion plate through an air conditioner adjusting support; the water pump driving wheel is arranged on a water pump which is fixed to the water pump cushion plate; the fan driving wheel is arranged on a fan, and the fan and the water pump are separately arranged on the water pump cushion plate through a fan support; the automatic tensioning wheel is fixed to a water pump cushion block; and the transmission belt is sequentially wound around the crankshaft shock absorber driving wheel, the water pump driving wheel, the fan driving wheel, the automatic tensioning wheel, the power generator driving wheel and the idle wheel. By means of the front end wheel train structure, the water pump and the fan are arranged separately, the speed ratio of the water pump, the fan, an air conditioner and a power generator is adjustable, suitability is good, the position of the fan is adjustable, and the requirements of a harvester, a forklift, a tractor and other market segments are met.

Description

technical field [0001] The invention relates to the field of engines, in particular to a front-end wheel train structure of a non-road diesel engine. Background technique [0002] Off-road engines are arranged in a compact vehicle, especially in tractors. This has higher requirements on the overall size of the diesel engine, and necessary adjustments must be made to the peripheral parts of the diesel engine to meet the supporting needs of the vehicle factory. At the same time, due to the different layout space and requirements of various market segments (forklifts, tractors, harvesters), the traditional front-end wheel train structure cannot meet the needs of each market segment at the same time, and different front-end wheel trains and special parts need to be designed . Traditional off-road diesel engine peripheral parts are scattered, which not only increases the size of the diesel engine, but also leads to too small wrap angle design of the front wheel train and freque...
