Abstract
The utility mode relates to a sub-frame with simple structure, strong bearing capacity and great bending strength, which is connected on the bottom of the automobile and used for connecting the damping mechanism and a stabilizing device. The utility model comprises a frame body stamped by a steel plate and welded by an upper body of the sub-frame and a lower body of the sub-frame and connection accessories of the frame body and is characterized in that: the frame body formed by the upper body of the sub-frame and the lower body of the sub-frame is fixedly connected with an arc tube; both ends of the arc tube extend to the upper parts of both sides of the upper body of the sub-frame and the arc tube is added to function as a strength beam, which greatly improves the strength of the sub-frame, thus increasing the bearing capacity and bending capacity of the sub-frame.
Description
Technical field
The utility model relates to the car body chassis component of automobile, specifically is exactly the parts that are connected the car body bottom and are used to connect damper mechanism and stabilizing device.
Background technology
The subframe that is provided with on the present car mainly is to weld the shelf component that the inside that constitutes forms cavity by subframe upper body and subframe lower body that steel plate is stamped to form, also is provided with on it and car body and other bulking block bonded assembly position.According to the general knowledge of strength of material as can be known, the load-carrying capacity of this subframe and bending strength are very limited.Especially in the suv vehicle, because the vehicle body deadweight is bigger, travel under the road conditions environment that vehicle jolts through being everlasting simultaneously, adopt the subframe of this class formation to highlight the defective of its concrete structure.
The utility model content
The purpose of this utility model just provides a kind of simple in structure, load-carrying capacity is strong and bending strength is big subframe.
For achieving the above object, the technical solution adopted in the utility model is: a kind of subframe, it comprises support body and the coupling thereof that the subframe upper body that is stamped to form by steel plate and subframe lower body are welded, it is characterized in that: also be fixedly connected with arc pipe on the support body that is made of subframe upper body and subframe lower body, the two ends of arc pipe extend to top, both sides, subframe upper body.
As shown from the above technical solution, the utility model is to have added an arc pipe component that can effectively improve whole subframe load-carrying capacity and bending strength on original subframe, because arc Guan Weiyi pipe rod component, its structure is very simple, the processing nature is very convenient, installs additional after the arc pipe, and it mainly plays the reinforcement beam action, greatly improve the intensity of subframe, thereby improved the load-carrying capacity and the bending-twisting ability of subframe.
Description of drawings
Fig. 1 is an exploded view of the present utility model;
Fig. 2 is an arc tubular construction scheme drawing of the present utility model;
Fig. 3 is the section A-A cutaway view in arc pipe stage casing.
The specific embodiment
Referring to Fig. 1,2,3, subframe disclosed in the utility model, it comprises support body and the coupling thereof that the subframe upper body 1 that is stamped to form by steel plate and subframe lower body 2 are welded, also be fixedly connected with arc pipe 3 on the support body that is made of subframe upper body 1 and subframe lower body 2, the two ends of arc pipe 3 extend to top, 1 both sides, subframe upper body.Above-mentioned subframe mainly is to be made of subframe upper body 1 and 2 welding of subframe lower body that steel plate is stamped to form, constitute the end face of enclosed cavity between the two, arc pipe 3 form by steel pipe compacting and with integral solder that subframe upper body 1 and subframe lower body 2 are welded be one.By Fig. 1,2 as seen, subframe also comprises left Control arm mount pad 4, go up right Control arm mount pad 5, brace panel 6,7, liner 8, sleeve pipe 9, right steering mechanism mounting bracket 10, left-hand control mounting bracket 11, bottom left control mount pad 12, bottom right control mount pad 13, the technical scheme of above-mentioned member can be referring to prior art.
Referring to Fig. 1,2,3, the middle part of described arc pipe 3 is positioned at the cavity inside of subframe upper body 1 and subframe lower body 2 welding back formations, and connecting panel 3a is set on the head of two ends, and it mainly is being connected and fixed of convenient and car body that connecting panel 3a is set.
The size of the above-below direction at described arc pipe 3 middle parts is greater than the size of horizontal direction, concrete is the elliptical ring shape with described arc pipe 3 middle part cross sectional shapes, near the two ends cross section is circular, the structure that can guarantee arc pipe 3 like this has comparatively simple form, job operation also is comparatively simple, promptly compacting is implemented at its middle part and be deformed into ellipse, can obtain ideal carrying and resistance to bending again simultaneously with pipe.Certainly, also can to adopt the cross section be that the pipe fitting in oblong cross section is bent into arc to arc pipe 3 in the utility model, in addition, the utility model can be the rod member bow of I-shaped with the cross section also, equally can implementation structure simple, carrying and the strong purpose of resistance to bending.
