Description
Technical field
The present invention relates to automobile body accessories manufacturing technology field, more particularly to a kind of lightweight automobile engine cover.
Background technology
In automotive field, the lightweight of automobile is to save one of the energy, important way of reduction discharge.The light weight of automobile
Change can improve dynamic property, economy, security and reduction exhaust emissions etc. by way of reducing automobile own wt, come
The purpose of energy-saving and environmental protection is reached, and action effect is clearly.Automotive light weight technology, is exactly to ensure automobile intensity and security
On the premise of energy, the combination properties such as the complete vehicle quality of automobile, and then dynamic property, the security of raising automobile are reduced as much as possible,
So as to reach the purpose of energy-saving and emission-reduction.
Automobile engine cover is the important component of automobile, and it had both played air conducting effect, and engine and week are protected again
Side pipe fittings etc., can also be substantially prevented from the adverse effect such as impact, burn into rainwater and electrical interference, and it is general in structure
It is made up of outside plate and inner panel, inner panel plays a part of strengthen rigidity, belongs to a kind of skeleton construction.
The main path of body lightening is generally divided into three aspects:Using Novel lightweight material, automotive body structure
Design optimization and advanced manufacturing forming process and interconnection technique.
Composite is generally made up of two kinds of combination of materials:Reinforcing material and matrix material.Reinforcing material can
Greatly increase the rigidity and intensity of matrix material；Matrix material is that reinforcing material bonds together, and protects reinforcing material, transmission
Load and the extension for hindering crackle.Reinforcing material is often threadiness, and composite has light weight, and intensity is high, and vibration damping insulates against sound,
Impact resistance, Resisting fractre toughness, fatigue resistance are good, are difficult that burn into is non-aging, and designability is good, the advantages of easy processing shapes.This
A little advantages cause composite also gradually to be found application in automotive field, and with the development of technology, composite is in the car
Utilization ratio will be increasing.
General bonnet is all directly welded after two formed by stamping thin steel plate in the prior art, internal
Steel plate is frequently with there is substantial amounts of cellular hollow out to realize lightweight.It is often each in the prior art to ensure the rigidity of bonnet
Sheet metal component has certain thickness, and cost is of a relatively high, and the quality of vehicle is also heavier, and the oil consumption economy to vehicle causes one
It is fixing to ring.
Auto parts and components are made using plastics and its composite, opposing metallic material has lightweight, and (density only has steel
The 1/6-1/7 of material density), the significant advantage such as the low, easy processing of cost, wherein most widely used is fibre reinforced composites.
And as SMC products, GMT products have, production efficiency is high, cost is low, easily return relative to other fibre reinforced materials for LFT-D products
The advantages such as regeneration, product are lighter, performance is strong are received, gradually replace SMC and GMT, as current automotive industry fiber-reinforced composite material
The developing direction of material.
A kind of lightweight automobile engine cover of present invention research and development, by LFT-D production lines using advanced composite material (ACM) one into
Type manufactures its outside plate and inner panel, compared to metal plate bonnet, has saved cost, effective to mitigate vehicle body overall weight, so as to reach
To the purpose for reducing oil consumption, saving the energy.
The content of the invention
The technical problem to be solved in the present invention is that the complete vehicle quality of automobile is heavier and members intensity is had a surplus, it is impossible to fully
Reach the purpose of energy-saving and emission-reduction.
