Embodiment Construction

[0026] figure 1 A sectional illustration of the transmission 10 with the inertial synchronization unit 12 and the gearwheel 14 is shown, wherein the gearwheel 14 is connected in a rotationally fixed manner to the clutch body 16 of the inertial synchronization unit 12 . In the illustrated embodiment—in which the clutch body has a disk-shaped shape—the clutch body is also referred to as a clutch disk. The clutch body 16 is in turn connected in a rotationally fixed manner to a separate friction ring 18 . In an alternative embodiment variant of the transmission 10 , the clutch body 16 and / or the friction ring 18 are of course also formed in one piece or in one piece with the gear wheel 14 .

[0027] The inertial synchronizing unit 12 comprises, on the outside of the clutch body 16 and the friction ring 18: a synchronizing body 20, which is mounted in a rotationally fixed manner on a shaft (not shown) of the transmission 10; a shift sleeve 22, the The shifting sleeve can be arran...

Abstract

The invention relates to a shift sleeve (22) for an inertial synchronization unit (12) of a transmission (10), which has an internal toothing (32) consisting of a plurality of shift sleeve teeth (34, 36). ), the shift coupling sleeve teeth extend in the axial direction relative to the shift coupling sleeve axis (A), and have an end face geometry on the axial end (38) respectively, wherein each two are in the circumferential direction (40 ) have different end surface geometries, and a plurality of shift engagement teeth (34, 36) evenly distributed in the circumferential direction (40) have the same end surface geometric shapes. Furthermore, the invention relates to a method for producing such a shift sleeve (22).

Description

technical field [0001] The invention relates to a shifting sleeve for an inertial synchronous unit of a transmission, which has an internal tooth portion composed of a plurality of shifting sleeve teeth, said shifting sleeve teeth being aligned with the shifting sleeve axis They extend in the axial direction and each have a face geometry at the axial ends. Furthermore, the invention relates to a method for producing such a shift sleeve. Background technique [0002] During operation of a transmission with an inertial synchronizing unit, disturbing scratching noises occur during gear shifting. These scratching noises often occur especially at low ambient temperatures and when shifting into higher gears, so this phenomenon known in the prior art is also referred to as "upshift scratching". [0003] In this case, although the rotational speed synchronization between the shifting sleeve and the gearwheel is achieved during the synchronization phase of the shifting process, it ...
