Problems solved by technology
which require, for example, costly screw connections or difficult-to-handle adhesives
Furthermore, the disadvantage of the bonding process is that the bonding process takes a relatively long time due to the necessary hardening of the adhesive, and the components have to be handled with great care during this time in order not to move the components relative to each other and thus weaken the bond connect
Production-technically advantageous welding can only occur in metal holders for magnets and unfavorably changes the magnetic field strength due to heat input
Ferromagnetic holders are also not sufficient to protect the magnets from undesired contamination

Embodiment Construction
[0034] Figure 1a to Figure 1d A first embodiment of the shifting device 1 according to the invention is shown. Only partly shown is the shifting element 2 in the form of a shifting sleeve 11 , which can be connected to a shifting shaft, not shown. The shifting sleeve 11 is designed as a tubular cylinder and is produced from an essentially flat sheet steel. The steel plates are rolled into a cylinder, the ends of which are locked to each other by means of dovetail connections 12 and unrolling of the tubular cylinder is prevented. While the steel sheet is still flat, the various recesses are punched into the steel sheet. Thus, one recess is introduced as gate guide 13 for securely guiding the selector lever, while the other recess serves as through recess 5 , 6 for engaging signal generator housing 3 . Radially on the outside, the selector sleeve 11 has further functional elements (for example detent contours 14 and selector paddles 15 ). The shifting sleeve 11 is thus desi...

The invention relates to a shifting device (1) of a motor vehicle transmission, having a shifting element (2) for selecting or shifting gear positions and having a signal transmitter housing (3) which has a signal transmitter (4) and which is fixed to the shifting element (2). The shifting element (2) has one or more through-recesses (5, 6), and the signal transmitter housing (3) has one or more retaining means (7, 8) which are arranged in the through-recess(es) (5, 6), said retaining means (7, 8) being secured on the rear face of the shifting element (2).
Description
technical field [0001] The invention relates to a shifting device of a motor vehicle transmission with a shifting element for selecting or shifting a transmission gear and with a signal generator housing which has a signal generator and is fixed on the shift element. Background technique [0002] In gear transmissions of motor vehicles, shift elements are usually used, for example in the form of shift shafts, shift forks or other transmission elements, most of which are translatable, but can also slide or rotate about an axis of rotation. [0003] In order to improve shift comfort and shift reliability it is necessary to ascertain the exact position of the shift elements in order to automate engine functions (eg start or stop) or to apply the gear positions for special shift strategies. In this case, it is known to use sensors for detecting the position of the shifting element. For example, DE 197 51 519 A1 discloses a linear sensor comprising a magnet and a Hall sensor in...
