Description
Technical field
The utility model relates to subframe technical field, specially a kind of lightweight fore sub frame assembly structure.
Background technique
Subframe can regard the skeleton of tandem axle as, be the component part of tandem axle.Subframe is not complete
Vehicle frame only supports the bracket of tandem axle, suspension, so that vehicle bridge, suspension is connected again with " positive vehicle frame " by it, is traditionally known as
" subframe ".The effect of subframe is barrier vibration and noise, reduces it and is directly entered compartment, so appearing in luxurious car mostly
On offroad vehicle, some automobiles are also that engine loads onto subframe.Conventional without the monocoque body of subframe, suspension is direct
It is connected with vehicle body steel plate.Therefore the suspension rocker arm body of tandem axle is all loose mail, not assembly.Subframe be born with
Afterwards, front and rear suspension can be first assembled on subframe, constitute an axle assembly, this assembly is then installed to vehicle together again
With.For subframe, main purpose is to reduce the incoming of road shock, and improve the company of suspension in performance
Rigidity is connect, therefore the driving of the vehicle equipped with subframe gets up to feel that chassis is very sturdy, it is very compact.And auxiliary frame suspension device is soft or hard
The setting of degree is also faced with as the contradiction that can not evade suspension adjustment.If auxiliary frame suspension device design is softer, that
The vibration that generates when can be good at completely cutting off running car, but excessively soft auxiliary frame suspension device design can in tempo turn band
Carry out biggish movement deformation, will lead to the inaccuracy of tire positioning in this way, to reduce the control stability of automobile.Harder
Auxiliary frame suspension device can bring very high coupling stiffness, but extremely limited to the isolation of vibrating noise.So engineers
It would generally be for the rubber packing of the positioning of vehicle and purposes selection proper stiffness when designing and matching subframe.
Existing lightweight fore sub frame assembly structure, is made using steel construction mostly, and weight is big, increases the weight of vehicle body
Amount, and one of an important factor for the weight of automobile itself is the oil consumption size of automobile, automotive dead weight is heavier, and the oil consumption of automobile is got over
Greatly, subframe however is not installed, the driving sense of vehicle is poor, in the vibration and vehicle traveling process that when engine operation generates
Driver's cabin can be passed directly to by jolting, and influence driver's operation, and traditional subframe cushioning ability is general, vehicle traveling process
In still have greatly vibration be transmitted to driver's cabin.
So how to design a kind of lightweight fore sub frame assembly structure, becoming us will currently be solved the problems, such as.
