Abstract
The utility model discloses a suspension arm, which comprises an arm main body with an approximate U-shaped cross section; the arm main body is provided with three support arms; a front liner assembly is fixedly connected at the end part of a first support arm of the arm main body; and a rear liner assembly is fixedly connected at the end part of a second support arm. The suspension arm further comprises a lower reinforcing plate; the lower reinforcing plate is connected to the first support arm and at the connecting part of the first support arm and the second support arm in a welding manner; and the lower reinforcing plate is connected onto the arm main body through the opening side of the U-shaped cross section of the arm main body in a welding manner. The suspension arm provided by the utility model can be under disperse stress at a narrow welding part in the sleeve position of a front liner, and has light weight and low probability of welding deformation.
Description
Technical field
The utility model relates to a kind of suspension arm, relates to particularly to be applicable to the suspension arm that adopts MacPherson type or similar suspension frame structure.
Background technology
Various types of suspension arms are known, as forms such as A type suspension arm, L type suspension arm, link-type suspension arm, trailing arms, and can be divided into tubular suspension arm, steel plate punch forming suspension arm, adopt suspension arm of reflectal technology manufacturing or the like from its structure and manufacturing process.
In the prior art, adopt comparatively generally for adopting the direct stamping forming suspension arm of steel plate, it is roughly two types again: a kind ofly be the direct stamping forming suspension arm of individual layer steel plate; Another kind of is the suspension arm that two plates are welded about adopting.First kind is adopted the direct stamping forming suspension arm of individual layer steel plate, as shown in Figure 1, generally all has an arm main body 1, arm main body 1 has the cross-sectional plane that is roughly U-shaped, one end of first support arm 11 of arm main body is fixedly connected with front lining assembly 2, the end that one end of second support arm 12 is fixedly connected with back bush assembly 3, the three support arms 13 is fixedly connected with ball end assembly 4.Its weight can alleviate greatly, and avoided welding deformation, reduced unsprung weight, can improve vehicle handling and stability and travelling comfort, but the intensity of this suspension arm is relatively poor, and the narrow weld zone at its front lining sleeve 20 places causes the weld strength deficiency easily, causes the stress concentration at this place simultaneously.
The suspension arm rigidity that is welded of two plates is higher up and down for second kind of employing, but its weight is big, cause cost to rise, and too much welding causes welding deformation easily.
Summary of the invention
For solving the problem that the narrow weld zone stress at its front lining sleeve place that the direct stamping forming suspension arm of individual layer steel plate of the prior art exists is too concentrated, and the suspension arm weight that two plates are welded about adopting is big, too much welding causes the problem of welding deformation easily, the utility model provides a kind of stress concentration phenomenon that can make at the narrow weld zone at its front lining sleeve place to alleviate lightweight, as to be difficult for causing welding deformation suspension arm.
The utility model provides a kind of suspension arm, comprise and have the arm main body that is roughly U-shaped cross-section, described arm main body has three support arms, the end of first support arm of described arm main body is fixedly connected with the front lining assembly, the end of second support arm is fixedly connected with the back bush assembly, wherein, described suspension arm also comprises lower reinforcing plate, described lower reinforcing plate is welded to connect in the connecting portion of described first support arm and first support arm and second support arm, and described lower reinforcing plate is solder-connected on the arm main body by the open side of the U-shaped cross-section of described arm main body.
Suspension arm of the present utility model, by only at described first support arm, and the connecting portion of first support arm and second support arm is welded to connect a lower reinforcing plate, can avoid large-scale welding deformation simultaneously losing the quality that alleviates whole suspension arm under the situation of intensity seldom to greatest extent; Because the stress on the suspension arm mainly is the position of weld that concentrates on the front lining assembly, and lower reinforcing plate of the present utility model and front lining assembly are welded to connect, strengthened the weld strength at the place, position of weld of suspension arm main body and front lining assembly effectively.
