Abstract
Description
The present invention relates to a retaining device for securing a stabilizer or a stabilizer bar to a suspension strut.
The present invention also relates to an automotive wheel suspension including at least one such retaining device, particularly a wheel suspension for a passenger car.
The stabilizer is a part belonging to a subcar of an automobile and contributes to improvement of road roadability. As disclosed in the patent publications US 6,305,701 B1 and DE 10 2006 036 506 B3, the present universal construction principle takes measures to fix the stabilizer directly to the suspension strut or to fix the stabilizer indirectly by means of the stabilizer bar. In addition, patent publication DE 30 27 694 A1 can also be referred to as prior art.
An object of the present invention is to provide a holding device for fixing a stabilizer or a stabilizer bar to a suspension strut, and to provide a holding device optimized for transmission of force.
Such a problem is solved by a holding device according to the invention having the features of claim 1. [ Thereby, the present invention at least indirectly covers the use of the retaining device claimed in the claims to secure the stabilizer or the stabilizer bar to the suspension strut. The solution to the above problem also includes an automotive wheel suspension according to the appended claims. Preferred constructions and additional constructions are likewise disclosed from the dependent claims and the subsequent description to the two inventive subject matter.
The retaining device according to the invention comprises an inner sleeve engaging around the suspension strut and an outer sleeve surrounding the inner sleeve (radially), wherein the outer sleeve comprises a securing section for securing the stabilizer or stabilizer bar ). Spherical segment-shaped sections that engage and extend generally about the entire circumference are configured in the inner sleeve and the outer sleeve to enable rotational compensation movement between the outer sleeve and the inner sleeve.
In other words, it is provided that the retaining device according to the invention has a first partial body with a first securing section for securing the retaining device to the suspension strut, and a second securing section for securing the stabilizer or stabilizer bar Means that the first partial body and the second partial body are connected to each other by a ball joint which enables a corrective movement, including a second partial body. According to the invention, the first partial body is formed as an inner sleeve engaging the periphery of the suspension strut and the second partial body is formed as an outer sleeve engaging the periphery of the inner sleeve, the inner sleeve and the outer sleeve overlapping Are configured to form sections of spherical segment shape that engage each other and extend over substantially the entire circumference.
The retaining device according to the invention has a number of advantages. In particular, the retaining device according to the present invention enables the transmission of optimized forces as will be explained in more detail below.
Between the inner sleeve and the outer sleeve, at least one rubber elastic body having mechanical and / or acoustic damping characteristics may be disposed. The rubber elastomer is protected from external influences by being disposed inside. It is preferable that the rubber elastic body is configured so as to extend entirely between the sections of the spherical segment shape.
It is desirable to configure the outer sleeve to be formed as a clamp (or pipe clamp). It is highly desirable that the outer sleeve formed as a clamp has slits extending in the axial direction with brackets projecting radially on both sides of the slits and the brackets being screwed together by at least one clamping screw . By tightening and tightening the clamping screw, the slit can be compressed and the outer sleeve can be narrowed. It is also preferred that the inner sleeve is provided with an axially extending slit and can be narrowed or narrowed indirectly by an outer sleeve formed as a clamp for securing the retaining device to the suspension strut.
The inner sleeve and / or the outer sleeve are preferably formed of a sheet metal material, especially a steel sheet material. The holding device thus formed is light and inexpensive. The steel sheet material is preferably a stainless steel sheet material and / or a coated steel sheet material. Sections of the spherical segment shape are produced by molding of the sheet metal material. In addition, the inner sleeve and / or outer sleeve may be formed as forged parts, cast parts, or lathe and / or milled parts.
An automotive wheel suspension according to the present invention, which is preferably a wheel suspension mounted on a rear axle of a passenger car and in particular on a passenger car front axle, is characterized in that the suspension strut and its suspension struts are fixed indirectly, either directly or via a stabilizer bar Wherein the stabilization of the stabilizer is effected by the retaining device according to the invention.
In the suspension cushioning process, a corrective movement between the stabilizer or the stabilizer bar and the suspension strut is possible by means of the retaining device according to the invention, in particular in the course of which the action line of the force of the stabilizer or the stabilizer bar intersects the centerline of the suspension strut, So that the compensating movement is possible so that the shear force and the moment acting on the suspension strut and especially the damper of the suspension strut are minimized. The present invention enables optimized stabilizer fixation for shear forces and moments so that the response characteristics of the suspension struts or dampers remain unaffected.
The suspension strut is a spring-damper strut, wherein the securing of the stabilizer or stabilizer bar takes place in the lower section of the damper housing, preferably in the lower half of the damper housing and especially in the lower 1/3. The wheel suspension according to the present invention may include a stabilizer bar (U-shaped bar) formed in an arcuate shape.
In addition, the wheel suspension according to the present invention may include an active adjustable stabilizer. The active adjustable stabilizer is made up of two parts, for example, an electric motor or an oil pressure unit, which can change the characteristics of the stabilizer, and which can be adjusted especially in accordance with the driving situation. In particular, it has been found to be very advantageous to minimize the shear forces and moments acting on the suspension struts and in particular on the dampers of the suspension strut, as already mentioned above, with respect to the undercarriage control system (e.g. active body control system) .
The present invention enables optimized stabilizer fixation for shear forces and moments so that the response characteristics of the suspension struts or dampers remain unaffected.
