Detailed description of the invention
By inventive feature, technological means and the specific purposes reached, function can be further appreciated that, below in conjunction with
The present invention is described in further detail by accompanying drawing with detailed description of the invention.
Refer to Fig. 1 to Fig. 6:
A kind of four-wheel electric vehicle carriage lightweight structure, includes two vehicle frame main beams 1, and vehicle frame main beam 1 two ends set respectively
Having forward mounting, rear-mounted, described vehicle frame main beam 1 is the aluminium alloy extrusions of square hollow, and aluminium alloy extrusions is the metal that comparison is light
Material, it is possible to be effectively reduced the weight of vehicle body, and there is good etch-proof performance.
Hollow aluminium alloy extrusions, is used as the vehicle frame main beam of vehicle, and its bearing strength is inadequate, therefore described
The inner chamber of vehicle frame main beam 1 is provided with support bracket 2, and described support bracket 2 is in X-type.The support bracket 2 of X-type substantially increases vehicle frame
The weight capacity of girder 1, and make vehicle frame main beam 1 more stable, it is unlikely to deform.
Concrete, described support bracket 2 comprises the first bracing frame 20 and the second bracing frame 21, described first bracing frame 20 He
Second bracing frame 21 cuboid the most in the form of sheets, described first bracing frame 20 intersects with described second bracing frame 21 and is connected；Described
The two ends of one bracing frame 20 connect one group of diagonal angle in described vehicle frame main beam 1, and the two ends of described second bracing frame 21 connect described
Another group diagonal angle in vehicle frame main beam 1.
The another aspect of body lightening is to improve suspension, and traditional suspension is to use steel plate to be used as hanging
Main body, the drawback of this suspension is, one is that steel plate itself is the heaviest, can increase the weight of the total amount of vehicle body, two be the elasticity of steel plate be whole
Body, a wheel produces if jolting, and car entirety can be made all to jolt, and its damping effect is bad, and three is the use longevity of steel plate
Order the longest, affect the use quality of overall vehicle.
Therefore, described forward mounting using the structure of double leval jib independent suspension, it includes front axle 31, described front axle
31 upper ends are respectively provided on two sides with a front spring 32, and described front spring 32 upper end is connected with the lower end of forward mounting installation position 3, vehicle frame master

Described front axle 31 is provided with front damper 5, and front damper 5 upper end connects the 3rd crossbeam 12, the 3rd 12 liang of crossbeam
End connects forward mounting installation position 3 respectively.Front damper 5 can buffer because of the vibratory forces produced of jolting further, can also delay simultaneously
Rush the elastic impact power produced because of front spring 32, thus further enhance the stability that vehicle travels, the comfort taken.
In like manner, described forward mounting being also adopted by the structure of double leval jib independent suspension, it includes the rear axle 41 of rectangle, after
Being respectively equipped with rear spring 42 above 41 4 angles of vehicle bridge, rear spring 42 upper end connects the lower end of rear-mounted installation position 4, vehicle frame main beam
1 side being positioned at rear-mounted installation position 4 is provided with the 4th crossbeam 13, is provided with the 5th connecting rod between the 4th crossbeam 13 and rear axle 41
43, the 6th connecting rod 44, the 7th connecting rod 45 one end and rear axle 41, its other end is connected with vehicle frame main beam 1, and rear axle 41 is remote
Connect from the side of the 7th connecting rod 45 and have the 8th connecting rod 46, the 8th connecting rod 46 liang one end connecting vehicle frame girder 1.
Being respectively provided with a rear damper 7 on four angles of described rear axle 41, one pair of which rear damper 7 upper end connects respectively
Connect the 5th crossbeam 14, the 5th crossbeam 14 two ends respectively with rear-mounted installation position 4；Another connects contiguous block to rear damper 7 upper end
8, contiguous block 8 is connected with the upper end of rear-mounted installation position 4.
One end that described vehicle frame main beam 1 is positioned at rear-mounted installation position 4 is additionally provided with the 6th crossbeam the 15, the 7th crossbeam 16.First
Crossbeam 10, to the setting of the 7th crossbeam 16, effectively raises the steadiness of vehicle frame main beam, and the carrying that improve vehicle frame overall is strong
Degree.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed, but also
Therefore the restriction to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that, for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement, these broadly fall into the guarantor of the present invention
Protect scope.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
