Description
Technical field
The utility model relates to technical field of automobile accessories, specially a kind of integrally casting hollow aluminium alloy fore sub frame.
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.Existing steel framework formula fore sub frame, finished weight is relatively high, and single-piece is more, and technique is relatively complicated, and material is corrosion-resistant
Property is poor, for this purpose, it is proposed that a kind of integrally casting hollow aluminium alloy fore sub frame.
Utility model content
The purpose of this utility model is to provide a kind of integrally casting hollow aluminium alloy fore sub frames, to solve above-mentioned background
The existing steel framework formula fore sub frame proposed in technology, finished weight is relatively high, and single-piece is more, and technique is relatively complicated, material
Expect the poor problem of corrosion resistance.
To achieve the above object, the utility model provides the following technical solutions: secondary before a kind of integrally casting hollow aluminium alloy
Vehicle frame, the inside including front beam, rear cross beam, left stringer and right vertical beam composition are the aluminium alloy fore sub frame of hollow structure, institute
It states and is provided with turning machine mounting hole at the top of the front surface of left stringer with the front surface of right vertical beam top, the left side of the left stringer,
Swing arm mounting portion, the left side top of the left stringer, right vertical beam are provided at left and right sides of the right side of right vertical beam and front beam
Right hand top and the left and right sides of rear cross beam be provided with vehicle body mounting hole, the left and right sides of the front surface of the front beam and after
The left and right sides of the front surface of crossbeam is provided with lightening hole, the front surface central location of the left stringer and the front surface of right vertical beam
Central location is provided with suspension mounting portion.
Preferably, the left and right sides of the rear surface of the rear cross beam is provided with stabiliser bar mounting hole.
Preferably, the fore sub frame is integrally formed using low pressure casting.
Preferably, the suspension mounting portion combines mach mode holding type installation using slush casting.
Preferably, the inner cavity of the fore sub frame is evenly arranged with reinforcing rib.
Compared with prior art, the utility model has the beneficial effects that a kind of integrally casting that the utility model proposes is empty
Heart aluminium alloy fore sub frame, since casting aluminium material density is only the 1/3 of steel, compared with conventional steel subframe, number of parts is significantly
It reduces, the complexity of technique is reduced while the intensity for guaranteeing product, performance, the weight of product is reduced, reduces oil
Consumption, using monoblock cast, improves the precision of fitted position, reduces recovery difficult.
