Embodiment Construction

[0042] Basis for synchronizers for shiftable gearshift transmissions Figure 1a The synchro ring 1 has a ring body 2 . The ring body 2 is arranged around the synchronizer ring axis 3 . The ring body has an inner friction surface 4 and an outer mounting surface 5 . The inner friction surface 4 and the outer mounting surface 5 delimit the ring body 2 in the radial circumferential direction. The ring body 2 has a toothing 6 extending from a gear base bar 7 which surrounds the ring body radially and is present at the end face of the ring body. The gear surface 8 extends substantially perpendicular to the synchronizer ring axis. The gear base strip 7 is axially delimited by a gear surface 8 . The gear base bar 7 supports the teeth of the toothed arrangement 6 . The recess 10 is arranged at the inner friction surface 4 of the ring body 2 such that the radius 14 of the inner friction surface at the end face 13 in the region of the recess 10 is greater than the radius 12 of the in...

Abstract

A synchronizing ring for a synchronizer of a shiftable transmission, comprising a ring body having a synchronizing ring axis, wherein the ring body has an inner friction surface and an outer mounting surface, wherein the inner friction surface and the outer mounting surface connect the ring body limited to a jacket face, wherein the ring body has an end face and a gear surface opposite the end face, wherein the synchronizer ring has a width corresponding to the shortest distance between the end face and the gear surface, and the jacket face extends between the end face and the gear surface, wherein the ring body has a toothing arrangement extending radially outwards from the outer mounting surface, wherein the toothing arrangement has a crown gear extending from the gear surface in the direction of the end face through a part of the width of the ring body, characterized in that, in A recess is arranged at the inner friction surface of the ring body such that the radius of the inner friction surface in the region of the recess is greater than the radius of the inner friction surface at the end face, and wherein a protrusion is provided at the outer mounting surface, which is arranged radially on the recess middle.

Description

technical field [0001] The invention relates to a synchronizing ring of a synchronizer of a shiftable gearshift transmission and to a vehicle gearshift. Furthermore, the invention relates to a synchronizer comprising a synchronizer ring of a switchable shift transmission. Synchronizers may be used in vehicle transmissions. The invention also relates to a method of manufacturing the synchronizer ring. Background technique [0002] Synchronizing rings in mechanical shiftable transmissions are used to match the relative speeds between the gears and the transmission shafts, which are produced when shifting gears. [0003] The transmission shaft is force-transmittingly connected to the corresponding gear wheel by means of a gear arrangement, so that the output shaft can be driven at the desired number of revolutions. A plurality of gears are arranged at the output shaft with different gear ratios. Accordingly, the rotational speed of the output shaft can be correspondingly hi...
