Embodiment Construction

[0021] exist figure 1 A part of the synchronization device 1 is shown in . The outer synchronous ring 8 , the synchronous intermediate ring 9 and the inner synchronous ring 4 form a ring group. Synchronizing body 10 is fastened on the transmission shaft by means of an internal toothing for a rotationally fixed arrangement. In addition to the synchronizing body 10 a gearwheel 11 is provided. The coupling body 2 is connected to a gearwheel 11 . The coupling body has recesses 12 into which entrainment projections 13 of the intermediate ring 9 engage. The mating friction surface of the intermediate ring 9 and the outer synchronizing ring 8 as mating cone forms a first friction pair 14 ; the mating friction surface of the intermediate ring 9 and the inner synchronizing ring 4 forms a second friction pair 15 . The gearwheel 11 is connected to the synchronizing body 10 via a sliding sleeve 16 .

Abstract

The invention relates to a synchronising device (1) of a variable speed transmission of a motor vehicle, comprising at least one clutch body (2) having an end face (3) and at least one synchronous ring (4) having an end face (5), wherein the end faces (3, 5) of the clutch body (2) and of the synchronous ring (4) are provided and designed for frictionally bearing against one another on a contact surface (6).

Description

technical field [0001] The invention relates to a synchronizing device for a gear transmission of a motor vehicle, comprising at least one coupling body with an end face and at least one synchronizing ring with an end face, wherein the end faces of the coupling body and of the synchronizing ring are arranged and designed to frictionally contact each other The contact surfaces rest against each other. Background technique [0002] A synchronization device of this type is known, for example, from DE 20 2006 019 959 U1. Such a synchronizing device also has a coupling body which is connected to a gearwheel of the transmission. Furthermore, there is usually a set of synchronizer rings which serve to adjust the rotational speeds of the components during the shifting process. Here, the synchronizing ring, in the known embodiment the synchronizing inner ring, rests frictionally with its end faces on the end faces of the coupling body (see DE 20 2006 019 959 U1 for this figure 1 )...
