Axle Carrier of a Vehicle Having a Bearing Part for an Anti-Roll Bar

Abstract

An axle carrier of a vehicle has a bearing part for an anti-roll bar. The bearing part has a bearing seat in the manner of a pipe clamp, is fastened releasably to the axle carrier, and is provided with a shaped-out formation which assumes a further function. The shaped-out formation is a lever arm which is oriented at least partially in the direction of the vehicle outer side and is designed so as to introduce a portion of the impact force into the axle carrier in the case of a vehicle impact with only a partial overlap. An additional supporting structure for reinforcement purposes for the case of an impact is provided on the bearing part, which supporting structure is fastened in a non-positive manner to a longitudinal carrier and to a crossmember of the axle carrier.

Claims

1. An axle carrier of a vehicle, comprising: a bearing part for an anti-roll bar, wherein the bearing part has a bearing seat formed as a pipe clamp, the bearing part is fastened releasably to the axle carrier, the bearing part is provided with a shaped-out formation having an additional function, the shaped-out formation is a lever arm oriented at least partially in a direction of an outer side of the vehicle, and the lever arm is configured so as to introduce a portion of an impact force into the axle carrier in an event of a vehicle collision with only a partial overlap.

2. The axle carrier as claimed in claim 1, wherein the bearing part comprises an additional supporting structure for reinforcement in the event of the vehicle collision, and the additional supporting structure is fastened in a non-positive manner to a longitudinal carrier and to a crossmember of the axle carrier.

3. The axle carrier as claimed in claim 2, wherein the additional supporting structure also comprises a section engaging around the anti-roll bar in a pipe clamp manner.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0015] FIG. 1 is an isometric illustration of an axle carrier with a bearing part according an exemplary embodiment of the invention, in which the axle carrier is only partially illustrated in an abstract manner.

[0016] FIG. 2 is a top plan view of the bearing part according to FIG. 1, in an installed state in a vehicle.

[0017] FIG. 3 is a side view of the bearing part in the installed state in a vehicle transverse direction.

DETAILED DESCRIPTION OF THE DRAWINGS

[0018] One exemplary embodiment is shown in the figures. Here, FIG. 1 shows an axle carrier (which is illustrated merely in a fragmented and greatly abstracted manner) having a bearing part according to the invention, in an isometric illustration, which bearing part is shown in a plan view (looking onto the roadway as viewed in the vehicle vertical axis direction) in FIG. 2 (in the installed state with the simplified axle carrier) and in a side view in FIG. 3 (as viewed in the vehicle transverse direction in the installed state). As far as the installed state is concerned as shown, the bearing part is fastened to the axle carrier in a vehicle in its left-hand front region.

[0019] The designation 2 denotes a frame-like and approximately rectangular axle carrier which is provided on the front axle of a double track vehicle, in particular a passenger motor vehicle, and is constructed from two longitudinal carriers 2a, of which only the left-hand one as viewed in the vehicle driving direction is shown here in a greatly abstracted manner, and two crossmembers 2b, of which only the front one as viewed in the vehicle driving direction is shown here in a greatly abstracted manner. The respective longitudinal carriers 2a are connected to the respective crossmembers 2b as customary, for example via cast nodes (not shown here). An anti-roll bar (not shown) is also mounted on the axle carrier 2. For this purpose, a pipe clamp-like bearing seat 11 is provided on a bearing part 1 which is denoted overall by the designation 1, is contiguous per se, and is produced in a casting process, for example. A short section of the anti-roll bar (not shown) which runs horizontally from left to right in the illustration of FIG. 2 lies in the semicircular-cylindrical bearing seat 11 of the bearing part 1. The bearing seat 11 is screwed releasably to the axle carrier 2 together with the bearing part 1 via screws (not shown) which are guided through receiving bores 15 in the bearing part 1, which bores 15 are provided on the two sides of the bearing seat 11 (on its semicircular shape in the manner of tangents).

[0020] A further essential constituent part of the bearing part 1 is a lever arm 12 which is designed, in the case of a vehicle impact with only a partial overlap, so as to absorb a portion of the impact and introduce it into the axle carrier 2. For this purpose, the bearing part 1 is connected releasably to the axle carrier 2 via further releasable screw connections. The lever arm 12 extends, as it were, starting from the bearing seat 11 of the bearing part 1, outward and forward at an angle of approximately 45 with respect to the driving direction of the vehicle. In order to then support the lever arm 12 as satisfactorily as possible on the bearing part 1 for the case where a high force K, which is directed substantially counter to the driving direction of the vehicle, acts on its free end in an accident-induced manner, a suitable supporting structure 13 is configured on the bearing part 1. The supporting structure 13 is designed in the form of two arms 13a, 13b which, in a manner which adjoins the lever arm 12 and the bearing seat 11 and at an angle of in each case approximately 120 with respect to the lever arm 12, extend rearward and inward toward the vehicle center plane in directions which are approximately opposed to one another. Further receiving bores 16 for fastening screws are provided in the end regions of the arms 13a, 13b, via which receiving bores 16 the bearing part 1 is fastened to the axle carrier 2. The arm 13a which is oriented approximately counter to the vehicle driving direction is supported in a non-positive manner on the longitudinal carrier 2a, and the arm 13b which is oriented approximately in the vehicle transverse direction (toward the vehicle center) is supported in a non-positive manner on the crossmember 2b.

[0021] The foregoing disclosure has been set forth merely to illustrate the invention and is not intended to be limiting. Since modifications of the disclosed embodiments incorporating the spirit and substance of the invention may occur to persons skilled in the art, the invention should be construed to include everything within the scope of the appended claims and equivalents thereof.
