The present approach relates to a switching element for receiving in a Ge housing means for adjusting a transmission setting for a vehicle, a

A switching device for a vehicle, a method for manufacturing and a method for operating a switching device.

In vehicles switching elements are used to set different conditions Getriebeeinstellun a vehicle transmission.

JP 2017-190050 A describes a Rastiersystem with a simple running Rastierelement.

Against this background, the present approach provides an improved Schaltele element for inclusion in a housing device for adjusting a gear set ting for a vehicle, also an improved switching device for a vehicle and a method of manufacturing and a method for operating a verbes serten switching device according to the main claims. Advantageous embodiments will become apparent from the dependent claims and the description below.

The achievable with the approach presented advantages are that a switching element presented here only requires a very small amount of space and because it is particularly stable in a switching device fixable.

A switching element for receiving in a housing device for adjusting a transmission setting for a vehicle comprises a first detent element and a two-Tes Rastierelement. The first detent element is designed to be in a received state of the switching element in the housing device in at least one switch position of the switching element in or on a first latching contour of

To lock housing device. The second detent element is designed to be in the switch position of the switching element in or on a second latching contour the housing means to lock to fix the switching element in the switch position in the housing means to allow the adjustment of the gear setting.

Such a switching element is advantageously formed to two times to lock on or in a housing device. Due to the double locking a particularly stable locking is possible in two places.

As the switching element may be understood an actuating lever for actuating a Schaltvorrich device for the vehicle. In different switch positions of the switching element in this case different transmission settings of a vehicle transmission can be selected, for example, at least one of Fahrstu fen P, R, N and / or D of an automatic transmission. For actuating the switching element can be arranged rotatably in the housing device along an axis of rotation or be arranged.

Preferably, the Rastierelemente are arranged so that the forces generated by the Rastie add up and act on the switching element that the axis of rotation of the switching element, which is preferably performed as a ball joint, is pressed in the direction of the bearing point of the axis of rotation. This eliminates freedom of play in the switching device. Thus, a switching element with an executed as a ball joint axis of rotation from different directions of forces are acted upon, which act to push the ball of the ball joint in the rich direction of the joint to design the switching device backlash.

The first detent element may in this case be arranged at a first end of a first jump of the switching element and / or the second detent element at a second end of a second projection of the switching element, in particular wherein the first projection and the second projection Kings arranged to be V-shaped Kings. V-shaped in the sense of the invention means that the respective directions of extension of the first projection or of the second projection form an angle of less than 180 degrees. The extension directions are therefore not parallel or tip-parallel. In other words, the protrusions are not directly opposite each other arranged. For example, the first detent element may be arranged at a first free end of the first projection of the switching element and / or the second Rastierele element at a second free end of the second projection of the switching element. The first and / or second projection may protrude in the form of a He lever.
