Abstract

The invention relates to a sliding sleeve (18) for a synchronizing device (10) of a gearshift (12), having a longitudinal axis (A), an internal toothing (34), which meshes with the In the external tooth portion (36) of the hub (14) of the synchronization device (10) and includes a plurality of sliding sleeve teeth (38), wherein each sliding sleeve tooth (38) is connected from the axial tooth end (40) extends to opposite axial toothed ends (42), and wherein said sliding sleeve (18) has an outer toothing (24) for engagement on a synchronizing ring (20) of said synchronizing device (10) The stop surface (44), and wherein the stop surface (44) is arranged axially between the tooth ends (40, 42) and with the two axial tooth ends (40, 42) Axially spaced apart. Furthermore, the invention also includes a synchronization device (10) having such a sliding sleeve (18) and a method for producing such a sliding sleeve (18).

Description

technical field [0001] The invention relates to a sliding sleeve for a synchronizing device of a gearshift transmission, having a longitudinal axis; an internal toothing which engages in an external toothing of a hub of the synchronizing device and which comprises a plurality of sliding sleeves teeth, and each sliding sleeve tooth extends from an axial tooth end to an opposite axial tooth end, and wherein the sliding sleeve has a stop surface for engaging on an external toothing of a synchronizing ring of a synchronizing device . [0002] Furthermore, the invention also relates to a synchronizing device for a shift transmission, which has 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 a coupling body between the sliding sleeve and the gearwheel to be shifted. Poor spe...
