Description
Technical field
The present invention 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.
Summary of the invention
The purpose of the present invention is to provide a kind of integrally casting hollow aluminium alloy fore sub frames, to solve above-mentioned background technique
The existing steel framework formula fore sub frame of middle proposition, finished weight is relatively high, and single-piece is more, and technique is relatively complicated, and material is resistance to
The poor problem of corrosivity.
To achieve the above object, the invention provides the following technical scheme: a kind of integrally casting hollow aluminium alloy fore sub frame,
Inside including front beam, rear cross beam, left stringer and right vertical beam composition is the aluminium alloy fore sub frame of hollow structure, described left vertical
Turning machine mounting hole, the left side of the left stringer, right vertical beam are provided at the top of the front surface of beam and at the top of the front surface of right vertical beam
Right side and front beam at left and right sides of be provided with swing arm mounting portion, the right side of the left side top of the left stringer, right vertical beam
Top and the left and right sides of rear cross beam are provided with vehicle body mounting hole, the left and right sides of the front surface of the front beam and rear cross beam
The left and right sides of front surface is provided with lightening hole, the front surface central location of the left stringer and the front surface center position of right vertical beam
It sets and 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 beneficial effects of the present invention are: a kind of integrally casting hollow aluminium alloy that the invention proposes
Fore sub frame, since casting aluminium material density is only the 1/3 of steel, compared with conventional steel subframe, number of parts greatly reduces, and is protecting
The intensity for demonstrate,proving product reduces the complexity of technique while performance, reduces the weight of product, reduces oil consumption, use is whole
Body casting, improves the precision of fitted position, reduces recovery difficult.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
In figure: 1 front beam, 2 rear cross beams, 3 left stringers, 4 right vertical beams, 5 turning machine mounting holes, 6 swing arm mounting portions, 7 vehicle bodies
Mounting hole, 8 lightening holes, 9 suspension mounting portions.
