Embodiment Construction

[0023] figure 1 A selector lever 1 according to the invention is shown in , which comprises a transmission tube 2 and a selector fork 3 . The shift fork 3 passes through two laser welded seams 4 (in figure 1 Only one weld 4) is shown in the figure to connect with the transmission tube 2.

[0024] The transmission tube 2 also has a detent contour 5 which is machined into the transmission tube 2 by rotary forging. The wall thickness of the transmission tube 2 can be limited to 1.5 mm by machining the detent contour 5 by rotary forging. With the directly welded connection of the selector fork 3 to the transmission tube 2 , a considerable weight saving is thereby achieved compared with conventional transmission tubes. It should also be pointed out that a plastic pad 6 is provided on the selector fork 3 and is intended to rest against other transmission components.

Abstract

The invention relates to a gearshift linkage (1, 11-14), in particular for a motor vehicle gearbox, comprising a shifting fork (3) and a gearshift tube (2, 21, 22), wherein the gearshift tube (2, 21, 22) is welded to the shifting fork (3) by means of laser welding.

Description

technical field [0001] The invention relates to a selector lever according to the preamble of claim 1 and to a method for producing a selector lever according to the accompanying method claims. Background technique [0002] Selector levers are known from the prior art, in which a transmission tube and a selector fork are connected to one another via a sleeve. One possibility for connecting the sleeve to the selector fork is to fasten the sleeve to the transmission tube by means of a clamping connection. A disadvantage of this connection technique and other known connection techniques is that they are labor-intensive and expensive due to the additional components. In addition, additional components bring about additional weight, so that such selector levers are relatively heavy. [0003] With regard to the shift tube, it should also be pointed out that since the detent contours are produced in the detent by milling, the detent must have a relatively high wall thickness, so ...
