Abstract: The invention relates to a control gear (1) for a synchronizing device of a change-speed gearbox, in particular of a motor vehicle, wherein a clutch body (2) is fixed to the control gear (1) by means of a weld (3) connecting the control gear (1) and the clutch body (2), and wherein the clutch body (2) extends over a radial height (H) from a radially inner end region (4) as far as a radially outer end region (5). In order to improve the quality of the toothing of the clutch body after welding and hardening, the invention provides that the weld (3) is arranged at a distance (a) from the radially inner end region (4).

Abstract: An assembly of crown wheel (12) and casing (11) of a differential gear assembly (10) is adapted to welding. The casing (11) has a circular flange (17) with an axially extending lip engaged in a circular groove (33) which is further relieved at the radially outer side to give clearance for a high energy welding beam (13). The interface between crown wheel (12) and flange (17) is preferably a frusto-conical surface (70, 65) which presents an oblique angle to said welding beam.
