Roll stabilizer

Abstract

A roll stabilizer in the form of a stabilizer bar which has a connecting portion at each end. The connecting portion is configured such that at least two bores are arranged on a circle arc. The center point of the circle arc constitutes the upper pivot point of the connecting element.

Claims

1. A roll stabilizer bar comprising: a formed connecting portion disposed at each end of the roll stabilizer bar for connection to a respective wheel-carrying part via a connecting element, wherein each formed connection portion is integrally formed on the roll stabilizer bar and includes a bifurcated end including two opposing connecting segments and a space disposed between the two opposing connecting segments that is sized to receive the connecting element, wherein each connecting segment of the two opposing connecting segments has at least two bores for connection to the connecting element, wherein different spring rates can be set using different bores of the at least two bores to connect the connecting element, wherein, for each formed connection portion, the at least two bores are arranged on a circle arc at the end of the roll stabilizer bar, and a center point of the circle arc lies at a pivot point of the connecting element.

2. The roll stabilizer bar as claimed in claim 1, wherein a length of a lever arm between a respective bore and the pivot point is constant.

3. The roll stabilizer bar as claimed in claim 1, wherein, for each formed connection portion, one of the at least two bores in each connecting segment is used for mounting to the connecting element.

4. The roll stabilizer bar as claimed in claim 1, wherein the roll stabilizer bar is composed of either spring steel or carbon steel.

5. A vehicle chassis of a vehicle comprising the roll stabilizer bar of claim 1, the respective wheel-carrying part and the connecting element.

6. The vehicle chassis as claimed in claim 5, wherein the connecting element is positioned in said space disposed between the two opposing connecting segments.

Description

BRIEF DESCRIPTION OF THE DRAWING FIGURES

(1) The invention is explained in more detail below with reference to three figures. The drawings show:

(2) FIG. 1 a schematic illustration of a stabilizer bar,

(3) FIG. 2 a schematic illustration of the connecting portion of the stabilizer bar and the arrangement of the bores, and

(4) FIG. 3 a schematic illustration of the vehicle chassis.

DETAILED DESCRIPTION OF THE INVENTION

(5) FIG. 1 shows a roll stabilizer 10 formed as a stabilizer bar 11 with connecting portions 20 arranged at each end. Each connecting portion 20 has three bores 30. However, two, four or more bores are also conceivable.

(6) FIG. 2 shows a connecting portion 20. This is configured such that three bores 30 are arranged on a circle arc 31, wherein the center point of the circle arc 31 constitutes the pivot point 50 of the wheel-carrying parts 52 (see FIG. 3). The lever arm 51 between the pivot point 50 and each bore 30 is constant in length.

(7) The spring rate of the stabilizer bar 11 can be adjusted by varying the bore 30 used for connection (see FIG. 3). For example, one spring rate of the stabilizer bar 11 is achieved if, in each case in mirror-symmetrically corresponding fashion, the bore 30 closest to the open end of the stabilizer bar 11 is used for connection to the wheel-carrying parts 52. The spring rate of the stabilizer bar 11 may be increased by using a middle bore 30 in one of the two connecting portions 20, wherein a mirror-symmetrically non-corresponding connection exists.

(8) FIG. 3 shows the vehicle chassis 40 with the stabilizer bar 11 which is mounted by the connecting element 41 at the connecting portion 20 and at the pivot point 50. The connecting portion 20 has three bores 30 which are arranged correspondingly to the connecting portion 20 of the stabilizer bar 11. Each formed connection portion 20 is integrally formed on the roll stabilizer bar 11 and includes a bifurcated end 13 including two opposing connecting segments 14 and a space 15 disposed between the two opposing connecting segments 14 that is sized to receive the connecting element 41. In an installation situation, the lever arm 51 exists between the bore 30 and the pivot point 50.

(9) The used bore 30 of the connecting portion 20 is here mirror-symmetrically corresponding or mirror-symmetrically non-corresponding in the connecting portions 20. For example, connection is possible at both connecting portions 20 in the bore 30 closest to the open end of the connecting portion 20. The stabilizer bar 11 (not shown) can however also be connected by a combination of two mirror-symmetrically non-corresponding bores 30, for example the combination of the bore closest to the open end of the connecting portion 20 and a middle bore 30 in the opposite connecting portion 20.

(10) Depending on the combination of bores 30 used on each side of the stabilizer at the connecting portions 20, different spring rates may thus be set.

(11) To summarize, the invention proposes a refined roll stabilizer in the form of a stabilizer bar. At least two bores in the connecting portion of the stabilizer bar are arranged on a circle arc, wherein the center point of the circle arc constitutes the pivot point 50 of the connection to the connecting element 41.

(12) The person skilled in the art will suitably modify the above-described exemplary embodiments or combine these with one another without deviating from the core of the invention.
