Description
Technical field
The invention belongs to Bus Manufacturing Technology field, and in particular to a kind of all-loading coach aluminium alloy chassis.
Background technology
According to GB30510《Heavy type commercial vehicle Fuel Consumption limit value》It is required that on May 26th, 2015, heavy-duty commercial vehicle
The second meeting of phase III Fuel Consumption standard limit the tenth tentatively proposes the year two thousand twenty and declined in 2015 on the basis of national standard
20~25% target.
Automotive light weight technology can reduce energy source of car and consume and accordingly reduce utilizing exhaust gas from coach discharge, reduce air pollution, simultaneously
The performances such as the control stability of vehicle, driving safety, riding comfort can also be improved.If it is demonstrated experimentally that vehicle complete vehicle weight
10% is reduced, fuel efficiency can improve 6%~8%；Automobile kerb weight often reduces double centner, and fuel consumption per hundred kilometers can reduce by 0.3
~0.6 liter；Vehicle weight reduces by 1%, and oil consumption can reduce by 0.7%.Currently, due to environmental protection and the needs of energy-conservation, the light weight of automobile
Change the trend for having become world car development.
