Problems solved by technology

[0003] The disadvantage of the known method is that relatively expensive magnets with very precisely reproducible properties have to be used for this purpose, in order to avoid as far as possible recalibration work and waste products, or to tolerate such recalibration work and such waste products
Turns out both raise the price of the shifter fork

Abstract

The invention provides a method for manufacturing a shift fork (1) for a transmission, wherein a substrate (2) with fork-shaped projections (3,4) is supplied and afterwards a magnetic position indicator (5) is fixed on the substrate (2). At least one magnet (6,7) is arranged in or on the position indicator (5). According to the method of the invention, an actual magnetic field (HI) which is generated through at least one magnet (6,7) is measured and at least one magnet (6,7) is positioned and / or oriented relative to the substrate (2), so that the actual magnetic field (HI) is arranged in a tolerance range (HT) of a rated magnetic field (HS) which is limited relative to the substrate (2).

Description

technical field [0001] The invention provides a method for producing a shift fork of a transmission, in which a base body is provided with the fork-shaped projections and a magnetic position indicator is fastened to the base body, in or on the position indicator At least one magnet is provided. Background technique [0002] Such a method is basically known from the prior art. For example, DE10337646A1 discloses a method for producing a shift fork of an automatically shifted transmission for this purpose, said shift fork comprising a shift fork position recognition device (in particular for a motor vehicle), wherein at least two prefabricated parts are passed through it Interconnected to make shift forks. In this case, a position indicator made of a magnetizable material is connected to one of the parts of the shift fork in the first non-magnetic state. Then, the various parts of the shift fork are connected to each other in a suitable position and are fixedly connected to...
