Embodiment Construction

[0030] With the help of Figures 1 to 3 A first exemplary embodiment of a toothed rack according to the invention, which is used, for example, in a steering system of a motor vehicle, is described. The toothed rack has a first rod-shaped component and a second rod-shaped component 1 , 2 which are connected to one another by means of a connecting piece 3 . The first rod-shaped component 1 has the toothing 4 of the rack as a functional element. This toothing 4 extends over a portion of the entire longitudinal extension of the toothed rack, so that this portion of the entire longitudinal extension of the toothed rack forms the first functional area of ​​the toothed rack.

[0031] The second rod-shaped member has a thread 5 as a functional element, for example for a ball screw drive. This thread extends over a part of the entire longitudinal extension of the toothed rack, so that this part of the entire longitudinal extension of the toothed rack constitutes a second functional a...

Abstract

The invention relates to a toothed rod or a threaded rod, particularly for a steering device for a motor vehicle, comprising a first rod-shaped pan which has at least one element for converting a rotational movement into a translational movement, said element being the functional element of the toothed rod or threaded rod, and being particularly a teething and / or a threading for engaging in a threaded nut or a threaded mechanism. The invention also has a second rod-shaped part which is connected to the first rod-shaped part and which preferably has at least one additional functional element ofthe toothed rod or threaded rod. The rod-shaped parts have hollow cavities which open toward connection ends in which connecting pins of a separate connection part are held by a press fit for the purpose of connecting the rod-shaped parts.

Description

technical field [0001] The invention relates to a rack or screw, in particular for a steering device of a motor vehicle, having a first rod-shaped member and a second rod-shaped member, the first rod-shaped member having at least one handle as a functional element of the rack or screw An element that converts a rotational movement into a translational movement, especially for engaging a toothing and / or a screw thread of a nut or a screw drive, the second rod-shaped member is connected to the first rod-shaped member and preferably has an additional rack or screw. At least one functional element, wherein at least one of the rod-shaped members has a cavity leading to the connecting end of the rod-shaped member, and a connecting tenon is fixed in this cavity by press-fitting for realizing connection with Connection of other rod-shaped members. Background technique [0002] Racks or spindles, such as those used in vehicle steering systems, generally have different functional are...
