Abstract

The invention relates to a sliding sleeve (18) of a synchronizing device (10) for a gearbox (12), which has a longitudinal axis (A), an internal tooth portion (34) which engages an external tooth portion (36) of a hub (14) of the synchronizing device (10) and has a plurality of sliding sleeve teeth (38); each sliding sleeve tooth (38) extends from an axial tooth end (40) to an opposite axial tooth end (42); the sliding sleeve (18) has restricted surfaces (44) for engaging an external tooth portion (24) of a synchronizing ring (20) of the synchronizing device (10); the restricted surfaces (44) are arranged axially between the tooth ends (40, 42) and are axially spaced from the two axial tooth ends (40, 42). In addition, the invention also comprises a synchronizing device (10) with the sliding sleeve (18) as well as a method for manufacturing such a sliding sleeve (18).

Description

technical field [0001] The invention relates to a sliding sleeve for a synchronizing device of a shifting transmission, which has: a longitudinal axis; an inner toothing which engages in an outer toothing of a hub of the synchronizing device and comprises a plurality of sliding sleeves teeth, and each sliding sleeve tooth extends from the axial tooth end to the opposite axial tooth end, and wherein the sliding sleeve has a stop surface for engaging on the outer toothing of the synchronizing ring of the synchronizing device . [0002] Furthermore, the invention also relates to a synchronizing device for a shifting transmission having such a sliding sleeve, and to a method for producing the sliding sleeve. Background technique [0003] Known inertial synchronizations for shifting transmissions have a stop geometry for locking the axial movement of the sliding sleeve as long as there is between the sliding sleeve and the adapter body of the gear to be shifted Poor speed. The...
