However, this arrangement is not entirely satisfactory
In particular, forming the annular boss on the cylindrical skirt of the main flywheel requires machining on the main flywheel, which is expensive, especially if precise radial outer dimensions of the boss are required to ensure that the boss is positioned relative to the fingers. proper positioning of the ends of the

Embodiment Construction

[0069] In the description and claims the terms "outer" and "inner" and the orientations "axial" and "radial" will be used to denote elements of a device according to the definitions given in the description. By convention, a "radial" orientation is orthogonal to the axis of rotation X of the device determining the "axial" orientation, and away from said axis from the inside to the outside, and a "circumferential" orientation is normal to the axis of the device and parallel to the radial direction Orthogonal. The terms "outer" and "inner" are used to define the position of one element relative to another by reference to the axis of rotation X of the device; therefore, elements near the axis are described as inner elements, rather than outer radially peripherally arranged element. In addition, the terms "rear" RR and "front" FR are used to define the position of one element relative to another in the axial direction, elements intended to be placed near the internal combustion e...

Abstract

The invention relates to a device (1) for a motor vehicle transmission chain, having: a rotary element (3) intended to be mounted so as to rotate about a rotation axis X, the rotary element (3) havingan axially oriented cylindrical skirt (8); a target (2) intended to be disposed facing a sensor that is able to deliver a signal representative of the angular position and / or speed of the target (2),the target (2) being secured to the rotary element (3) and having an annular ring (17) which extends axially and is disposed circumferentially around the cylindrical skirt (8) of the rotary element (3), the annular ring (17) having fingers (18) which extend parallel to the axis X and separate windows (19, 21) from one another that are distributed around the axis X, each finger (18) having a distal end (20); and a protective annulus (22) which is secured to the rotary element (3), said protective annulus (22) having an internal bearing portion (23) positioned radially between the distal end (20) of the fingers (18) and the cylindrical skirt (8) such that the distal end (20) of each finger (18) is able to bear radially inwardly against said internal bearing portion so as to limit the deformation of the annular ring (17).

Description

technical field [0001] The invention relates to the field of motor vehicle transmission lines, and more particularly to a motor vehicle transmission line arrangement provided with a target intended to be arranged facing a sensor. Background technique [0002] DE102008023869 discloses a main flywheel of a dual mass flywheel provided with a target. The target includes a radially oriented flange secured to the cover of the main flywheel and a plurality of fingers extending axially from the periphery of the flange all around a cylindrical skirt of the main flywheel. Thus, when the dual mass flywheel rotates, the fingers generate a magnetic field change that can be detected by a sensor arranged facing the target. Thus, such sensors are capable of transmitting signals indicative of the angular position and / or velocity of the target. The distal end of each finger bears against an annular boss projecting radially outward from the cylindrical skirt of the main flywheel. This makes...
