Problems solved by technology

In this case, therefore, the different gears have the same position of the signal transmitter and the sensor, so that in a shifting unit with shifting element and sensor stop, the different shifting positions of the shifting element are not aided by other means cannot be kept separately

Embodiment Construction

[0028] figure 1The schematic diagram of the figure shows a cross-section of an embodiment of a rolling bearing 1 according to the invention, which comprises a first part 2 as a shift fork shaft 15 with a rectangular cross-section, which can be axially Mounted in a movable manner (that is to say perpendicular to the drawing plane) in the second part 3 as transmission housing 17 . On the outer circumference of the shift fork shaft 15 is arranged the inner sleeve 4 as a sheet metal profile, which is used as an internal guide for the rolling elements 5 which are only schematically shown in the drawings, and these rolling elements are in the present embodiment respectively Formed by spheres. The inner sleeve 4 has three guide sections 6 distributed over the circumference, which extend axially and have a circular section in cross-section. The radius of the circular segment corresponds to the radius of the rolling elements 5 so that they are enclosed and guided over a defined area....

Abstract

The invention relates to a roller bearing (1) for two components (2, 3) that can be at least axially moved toward one another, wherein the roller bearing (1) has roller elements (5) that are arranged in at least two rows which are aligned in the axial movement direction, and first tracks (6) for the roller elements (5) that are arranged on the first component (2) and second tracks (8) for the roller elements (5) that are arranged on the second component (3), wherein the roller bearing (1) has sensor equipment with a signal encoder (22) and a sensor (21) comprising two sensor elements (13, 14), the first sensor element (13) is arranged in an immobile fashion relative to the first component (2) and the second sensor element (14) is arranged in an immobile fashion relative to the second component (3).

Description

Background technique [0001] As described in DE 10 2006 028785 B3, there is an increasing need to use sensors to detect possible positions between axially movable components and in particular within a transmission. In manual transmissions, a magnet is attached to or next to the shifting element for this purpose, generally this is the central shifting shaft with one or more selector lever fingers arranged in the selector housing. The magnets interact with Hall sensors arranged in the selector housing and detect the individual gears. The disadvantage of this construction is that the magnets attract ferrous abrasive particles present in the transmission housing oil. The magnetic field characteristic curve during its service life is changed by the adsorption of this dirt. The detection accuracy thus decreases during operation. [0002] In order to avoid this disadvantage, especially in automatic transmissions, the gear position is usually directly detected by the generally linea...
