Abstract
An engine accessory wheel train comprises a first layer belt wheel train and a second layer belt wheel train, wherein a first belt wheel is sequentially connected with a pulley, a water pump pulley, an engine pulley and an air-conditioning compressor on a torsional buffer to form the first layer belt wheel train, a front end pulley of the torsional buffer directly drives a fan pulley through a second layer belt wheel so as to form the second layer belt wheel train, the second layer belt wheel train is superposed on the first layer belt wheel train, and the front end pulley of the torsional buffer and the pulley of the torsional buffer are drived coaxially. Considering the arrangement of the wheels and the reliability of belt transmission, in the first belt wheel train, a first tensioner is positioned on a belt between the pulley of the torsional buffer and the water pump pulley, a first idle pulley is positioned on a belt between the water pump pulley and the engine pulley, a second idle pulley is positioned between the air-conditioning compressor and the pulley of the torsional buffer, furthermore, a second tensioner is arranged outside the second layer belt. With the accessory of the wheel train arrangement, the free arrangement of each part is facilitated, the assemblage of the parts in the wheel train becomes much easier, the transmission efficiency is enhanced, and the transmission noise is reduced.
Description
Technical field
The utility model relates to a kind of engine accessory wheel system, especially relates to a kind of heavy-duty engine accessory wheel system system.
Background technique
In the common in the past engine accessory wheel system, has plenty of whole accessory wheel system with a belt drives.Engine accessory wheel system is arranging that there are a lot of deficiencys aspects such as transmission.The one,, such layout, because power that fan consumed is bigger, in the accessory wheel system, other parts all will bear the big radial force that the big load owing to fan brings, and its bearing is just had higher requirement.The 2nd, because the engagement and the neutral of fan clutch, the shock effect of tackling accessory wheel system mutually is also bigger.And the consumed power total owing to train is bigger, and the corresponding accessory belt will be more, wide than the belt ribs number of single driving fan.In addition, when belt lost efficacy, because water pump is not worked, corresponding motor can not the on-load running.The 3rd,, existing whole accessory wheel system is very complicated, and end spaces is limited before the cylinder body, layout is subjected to a lot of restrictions, and it is optimum that the efficient of transmission can not reach, and the tension force of belt is difficult to control, the planeness to neutral and each belt pulley of train requires high, increases manufacture cost, easily produces noise.Have plenty of on the torsional balancer that fan is directly installed on bent axle, the size of motor length direction will increase, and be subjected to the restriction that motor and car load are arranged.
Summary of the invention
The purpose of this utility model is the deficiency that exists in the available engine accessory wheel system to provide a kind of engine accessory wheel system.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of engine accessory wheel system comprises first layer belt train, and described first layer belt train connects belt wheel, Water-pump belt wheel, generator belt wheel, air condition compressor on the torsional balancer in proper order by first belt.Second layer belt train is set, and described second layer belt train is made up of by the direct drive fan belt wheel of second layer belt torsional balancer front end belt wheel; Described second layer belt train is superimposed on the first layer belt train, and the driving wheel of second layer belt train is a torsional balancer front end belt wheel, torsional balancer front end belt wheel be with torsional balancer on the belt wheel Driven by Coaxial.
Layout and the bel-drivenn of considering each wheel are reliable, in the described first layer belt train, first stretcher are set on belt between belt wheel on the torsional balancer and the Water-pump belt wheel; Belt is provided with first idle pulley between Water-pump belt wheel and generator belt wheel; Air condition compressor with connect torsional balancer on belt wheel between second idle pulley is set.
Consider that second bel-drivenn is reliable: in the described second layer belt train, outside second layer belt, also be provided with second stretcher.
Good effect of the present utility model, the utility model handle is loaded less torsional balancer, water pump, generator, air condition compressor belt wheel as first layer belt train; By independent train transmission, fan and torsional balancer front end belt wheel are as second layer belt train the bigger fan of loading.Such layout is isolated the influence of fan clutch, and fan belt inefficacy rear engine still can be kept little load operation.Reduce the complexity of every layer of belt in addition, improved belt working life.Improve Belt Transmission Efficiency, reduced the mechanical noise of accessory wheel system.Layered arrangement accessory wheel system like this is convenient to the layout of each component, reduces the complexity of accessory wheel system, makes the easier control of tension force of belt, and train can be obtained better neutrality, raising transmission efficiency and belt working life, reduction noise.
Arrange that by accessory wheel system of the present utility model it is free more that each component will be arranged, the assembling of wheel based part is simpler.This design can improve transmission efficiency, reduces the engine mechanical lost work, reduces rotational noise, for exploitation energy-conserving and environment-protective h type engine h is offered help.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
