Description

The The invention relates to a link component, in particular a spring link, according to the features in the preamble of claim 1.

By the DE 10 2006 032 595 A1 includes a spring link for a suspension of a motor vehicle to the prior art. The spring link has a one-piece base body in the form of a spring link shell with a first end portion to the vehicle body-side connection and a second end portion for wheel-side connection. In the central region of the body an extended portion is provided for supporting a spring or a spring-damper assembly. The end portions as well as the middle portion have a U-shaped profile. Within the middle extended portion an outwardly everted annular surface is provided, which serves as a spring seat. This is intended to increase the rigidity in the region of the spring support.

Also from the DE 10 2006 014 730 A1 is known a one-piece spring link.

The known one-piece spring links represent an innovative step in the direction of a simple and inexpensive lightweight construction at least sufficient rigidity. Due to the between the spring and damper forces acting on the end sections The spring links are subject to heavy loads. this applies especially for the area of spring rest, in which it due to strong bending stress to profile widening of the Body can come.

Of the Invention is therefore based on the prior art, the task At the bottom, a spring link of the generic type for the operational use, in particular with regard to its stiffness behavior, to improve in highly stressed areas without losing its weight disadvantageously increase.

The Solution to this problem consists according to the invention in one Handlebar component, in particular a spring link, according to the Features of claim 1.

crux the invention forms the measure that the open pages the end portions of the body in different from each other Directions. The end sections have a U- or V-shaped Configured profile with two legs that over one Bridge are connected and an open side. Learn according to the invention the end portions of the body in terms of orientation their offside a change of direction and are to each other twisted. This change of direction or twist in longitudinal extension of the body leads to a significant increase stiffness, especially in the heavily loaded middle area of the body, and without adverse weight increase. By the rotation of the end portions to each other, the resistance moment of the main body as a result of the geometry change and increasing or increasing the load-bearing Wall surface enlarged, resulting in a corresponding Increasing the stiffness of the handlebar in highly stressed areas, especially in the central region of the body.

advantageous Embodiments and developments of the fundamental Concept of the invention are the subject of the dependent claims 2 to 12.

at a particularly advantageous embodiment for practice of the link component according to the invention are the Open sides of the end sections rotated 180 ° to each other, whereby the stiffness in the middle area of the main body is significantly increased. In particular, this stands in the middle Area of the main body more bearing wall surface for stiffening the handlebar component available.

The Loading behavior and the rigidity of the handlebar component can continue to be increased when attached to the outer Ends of the legs at least partially connect transversely projecting flanges. Basically, the flanges on the outer Ends of the legs are directed inwards or outwards, in particular outwardly directed flanges being particularly be considered advantageous.

in the middle region of the main body is a cup-shaped, formed widened towards the end portions recording. This serves to support a spring or a spring-damper arrangement, which in turn is supported against the vehicle. to Positioning of the spring is in the bottom of the receptacle one upwards directed indentation provided. The invagination is formed in one piece in the body. This measure leads to an improved stiffening in the area of Spring support with optimized weight. Furthermore, the assembly the spring as well as the fixation improved. By in the direction Injection directed to the opening of the receptacle In addition, the Biegewechselbelastung in the middle region of the body during compression and rebound operations under operational load be counteracted.

In the legs of the end portions openings in the form of holes and / or recesses are provided. These serve to connect the handlebar component within a force vehicle, in particular for fixing the link component on the wheel, on the subframe or generally from the vehicle body. Furthermore, stabilizers or shock absorbers can be defined at openings or stop openings in the handlebar component.

Preferably the openings are at least in one end section as passages executed with circumferential collar. In particular, here are the collars of each other in the thighs coaxially opposite Pulling towards each other. Such passages with circumferential collar provide a purpose-optimized connection point with high rigidity and optimized support, for example, for a bearing component or a sleeve.

to Increasing the rigidity of a body, for example in particularly heavy vehicles such as off-road vehicles, can on or in the body stiffening plates be arranged. In particular, such stiffening sheets are horizontal arranged in the main body, as partial strike plates, extending between the ends of the legs of the main body extend. Furthermore, the main body with a internal or external partial reinforcement be provided. Such reinforcements may be, for example from a sheet metal or fiber reinforcement exist in particularly critical and highly stressed areas of the main body inside and / or outside of the base body are joined.

Of the The base body is preferably made of metal, in particular from a sheet steel or even a light metal, with a Sheet thickness of 1.5 to 2.5 mm, preferably about 2.0 mm.
