Description
Technical field
The utility model is related to automobile manufacturing field, specifically a kind of automobile door type bracket of trailing arm structure.
Background technology
The today developed rapidly in car industry, the structuring concept of hardware and software platform can not only meet frequently vehicle conversion need
Ask, and exploitation and production cost can be reduced；Automobile part dynamic stiffness is increasingly paid close attention to by user, directly affects automobile
Organoleptic quality and NVH performances；Increasingly lower oil consumption demand proposes strict requirements to body lightening.More than consideration
In the case of demand, the utility model provides a kind of bracket of trailing arm structure, it is ensured that while vehicle platform part is general, meets
NVH performance requirements, and reach the purpose of loss of weight.
Utility model content
The utility model provides a kind of automobile door type trailing arm supporting structure, fundamentally solves above mentioned problem, its
With simple and compact for structure, convenient to use, maintenance cost is low, service life is longer, the low advantage of fault rate.
To achieve the above object, the utility model provides a kind of automobile door type bracket of trailing arm structure, including rear vertical
Beam reinforcer and middle floor, are characterized in that：The door type bracket of trailing arm structure outer ring is provided with the first flange, second
Flange and the 3rd flange, inner ring are provided with the 4th flange, and four turnup structures form the arrying main body of the part, the first flange
It is connected by C02 welding manners with floor side member reinforcer, the second flange is connected by spot welding mode with floor side member reinforcer, the 3rd
Flange is connected by structure glue with middle floor, and the 4th flange, which has, avoids function while also reaching loss of weight purpose.
The beneficial effects of the utility model：By the design of bracket of trailing arm, the supporting construction of hardware and software platform is obtained, is met
NVH performance requirements simultaneously realize lightweight, while the design of this bracket of trailing arm reduces cost per unit, reduce logistics and workshop
Fixture cost.

Description of reference numerals：
1st, the first flange 2, the second flange 3, the 3rd flange 4, the 4th flange 5, floor side member reinforcer
6th, floor side member 7, spot welding 8, CO2Welding 9, middle floor 10, multi link back axle 11, torsion beam rear axle.
Embodiment
Below in conjunction with Fig. 1 ~ 4, content of the present utility model is described in detail by specific embodiment.The technology of the utility model
Scheme is：A kind of automobile door type bracket of trailing arm structure, including floor side member reinforcer and middle floor, wherein the door type is dragged
Drag arm support structure outer ring and be provided with the first flange, the second flange and the 3rd flange, inner ring is provided with the 4th flange, four flange
Structure forms the arrying main body of the part, and the first flange is connected by C02 welding manners with floor side member reinforcer, the second flange
It is connected by spot welding mode with floor side member reinforcer, the 3rd flange is connected by structure glue with middle floor, the 4th flange, which has, to be kept away
Function is allowed while also reaching loss of weight purpose.
Operation principle is as follows：The turnup structure of door type bracket of trailing arm structure outer ring design first, second and third, door
Font bracket of trailing arm structure inner ring designs the 4th turnup structure.Four turnup structures form the arrying main body of the part.Together
When first, second, third flange also become the medium being connected with peripheral component.As shown in Fig. 2 the first flange is welded by C02
Connect and be connected with stringpiece reinforcement；Second flange is connected by spot welding with floor side member reinforcer；3rd flange is by structure glue with
Floor is connected；Above connected mode is the existing technology mode of existing production, and without increasing cost, connected mode is simple and reliable.
The 4th flange has the purpose that loss of weight has also been reached while avoiding function on the inside of door type.
Bracket of trailing arm position is shown in Fig. 3, and bracket of trailing arm is arranged in four towing arms and installs to be formed rectangular
Position of center line, can play good intermal force.While meeting local mount point intensity, make the dynamic of towing arm mounting bracket
Rigidity improves 2000N/mm in Z-direction.The design of the bracket of trailing arm, makes the material thickness of floor side member be kept to 1.8mm by 2mm, after making
The material thickness of stringpiece reinforcement is kept to 1.8mm by 2.5mm, realizes vehicle loss of weight 2.3Kg.Important tribute is made for the lightweight of vehicle
Offer.
Bracket of trailing arm matches different back axle schematic diagrames as shown in figure 4, same bracket of trailing arm realizes two kinds of matching
Back axle is configured.While the design of this bracket of trailing arm reduces cost per unit, logistics and workshop fixture cost are reduced.
