Description
Technical field
The present invention relates to subframe technical field, specially a kind of hollow low pressure casting multi link 4 wheel driven of Integral aluminum alloy
Rear secondary frame for vehicle.
Background technology
Traditional subframe is solid aluminum alloy subframe and is split casting welding aluminum alloy Rear secondary frame for vehicle, heavier-weight,
Some areas unqualified thickness reason, forming defect is larger, and rigidity, mode can not meet actual demand, Welded technological requirement
Height, welding procedure are complicated.
The content of the invention
It is an object of the invention to provide a kind of hollow low pressure casting multi link 4 wheel driven Rear secondary frame for vehicle of Integral aluminum alloy, with
The vehicle frame unqualified thickness for solving to propose in above-mentioned background technology is managed, forming defect is larger, rigidity, mode can not meet actual need
Ask, the problem of welding procedure is high, welding procedure complexity.
To achieve the above object, the present invention provides following technical scheme：The hollow low pressure casting multi link of Integral aluminum alloy
4 wheel driven Rear secondary frame for vehicle, including subframe, the antetheca corner of the subframe are provided with installation set, the antetheca of the subframe from
Top lightening hole, middle part lightening hole, bottom lightening hole have up to been disposed with down, and the bottom of the subframe has been provided with bottom
Lightening hole is held, the rear end lower of the subframe is provided with rear portion lightening hole, and the left and right portion in antetheca bottom of the subframe is all provided with
Reinforcement is equipped with, the left and right top of antetheca of the subframe is provided with upper swing arm installing plate, upper swing arm installing plate described in two groups
Top be provided with pilot hole, the left and right top of antetheca of the subframe is provided with stabiliser bar mounting hole, the stabiliser bar
Mounting hole site is in the inner side of upper swing arm installing plate.
Preferably, the subframe is aluminum alloy auxiliary vehicle frame.
Preferably, the subframe is integrated casting and machining.
Preferably, the inwall casting of the subframe needs to increase core.
Compared with prior art, the beneficial effects of the invention are as follows：This programme is rational in infrastructure, lighter in weight, and thickness of slab distribution is equal
Even, beneficial to casting, rigidity, mode meet demand, integrally casting, welding requirement, the aluminum alloy auxiliary vehicle frame is hollow knot
Structure, by increasing reinforcement and hollow-core construction itself can obtain higher mode, then by topological optimization by the less portion of stress
Position material removes, and reduces subframe weight as far as possible, and aluminum alloy auxiliary vehicle frame can bring good suspension coupling stiffness, can completely cut off
Road shock brings good comfortableness, and the more traditional steel subframe of aluminum alloy auxiliary vehicle frame is in light weight, and pliability is good, has pole
High active safety and dynamic operation, while also bring the fuel consumption of economy.
