A kind of aluminum truss type frame
The present invention relates to a kind of vehicle frame technical field, particularly relate to electric space vehicle field.
Along with petroleum resources day by day reduce, atmospheric environment seriously polluted, electric motor car is increasingly by people
Concern.The most light-weighted electric automobile is increasingly becoming the preferable vehicles that the mankind ride instead of walk.I
Know that vehicle frame weight accounts for the proportion that complete vehicle weight is bigger, so car load lightweight should be light from body frame structure for automotive
Quantitative design is started with, thus reduces complete vehicle quality, reduces energy resource consumption.Carriage frame uses mostly at present
Straight frame, central frame or composite type vehicle frame.But these traditional steel construction vehicle frames manufacture work
Skill is complicated, and structure is not sufficiently stable, and bending resistance torsional property is the best, and heavier mass, affects car load lightweight
Design, is unfavorable for automotive energy-saving emission-reducing.
Summary of the invention
The invention provides a kind of aluminum truss type frame be easy to and manufacture.
For achieving the above object, the present invention provides a kind of aluminum truss type frame, it is characterised in that include car
Frame support framework, front suspension assembly and rear suspension assembly, wherein vehicle frame support framework includes that cross section is identical
And front beam, middle cross beam, rear cross beam, right vertical beam and the left longeron being mutually permanently connected.
Compared with prior art, aluminum truss type frame of the present invention includes cross section phase by vehicle frame support framework
Same and that be mutually permanently connected front beam, middle cross beam, rear cross beam, right vertical beam and left longeron, thus available same
The section that piece aluminium section bar intercepts out certain length is fixed connection again, consequently facilitating manufacture, cost is lower.

Detailed description of the invention
It is only a present invention part below in conjunction with the embodiment described by the accompanying drawing in the embodiment of the present invention
Embodiment rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill people
The every other embodiment that member is obtained under not making creative work premise, broadly falls into the present invention and protects
The scope protected.
It is below specific embodiment, sees Fig. 1 to Fig. 5.
In the embodiment of the present invention, aluminum truss type frame include vehicle frame support framework, front suspension assembly and after
Suspension assembly, wherein vehicle frame support framework include that cross section is identical and be mutually permanently connected front beam 2, middle horizontal stroke
Beam 9, rear cross beam 12, right vertical beam 1 and left longeron 18.
Described front suspension assembly may also comprise identical with vehicle frame support framework cross section and before being mutually permanently connected
Outstanding trailing arm 3, front overhang pole 4, front overhang fixed plate 5 indulge frame 6 with front overhang.
Described rear suspension assembly may also comprise identical with vehicle frame support framework cross section and after being mutually permanently connected
Outstanding trailing arm 10, rear overhang crossbearer 13 and rear overhang crossbeam 13.
Described rear suspension assembly also includes being respectively fixedly connected with in right vertical beam 1 and the longitudinal direction of left longeron 18 lower end
Stabiliser bar hangers 15, to be fixed on the longitudinal balance bar (not shown) of rear suspension system on vehicle frame.
In the present embodiment, aluminum truss type frame puts seat installing rack assembly in also including, it puts seat in being provided with
Chair installing rack 7.In put seat installing rack 7 and be weldingly fixed on right vertical beam 1 and a left side by one block of T-shaped aluminium sheet and indulge
Beam 18 upper end, simple in construction.Connecting plate is T-shaped aluminium sheet, and structural strength is higher.
In the present embodiment, the identical material in the above cross section is I-shaped aluminium section bar.Certainly, it is possible to part
For I-shaped aluminium section bar, such as vehicle frame support framework, front suspension assembly and wherein in rear suspension assembly
Part or two parts.
In the present embodiment, described fixing connected mode is welding.Certainly, it is possible to for riveting, but welding
Fixed effect is preferable.
Being provided with battery compartment frame 16 in the middle part of aluminum truss type frame, it is respectively welded at right vertical by four I-shaped aluminum
Beam 1 and left longeron 18 lower end, to form battery compartment, house the accumulator battery connected by battery connecting line 8
17.So, the height of battery compartment can be reduced, thus reduce the center of gravity of car load, be conducive to reducing driving
Resistance, reduces energy resource consumption.
Weld two seat legs 14 in rear suspension, two seat legs 14 weld an aluminium sheet and forms back seat peace
Shelve 11, simple in construction.Seat leg 14 is T-shaped aluminium sheet, and structural strength is higher.
A kind of aluminum truss type frame provided the embodiment of the present invention above is described in detail, herein
Apply specific case principle and the embodiment of the present invention are set forth, be only used for helping to understand this
Invention core concept；Should not be construed as limitation of the present invention.
