Embodiment Construction

[0035] figure 2 The synchronizer ring 7 shown in includes a base body 8 on which radially outwardly extending indexing cams 9 and centering surfaces 10 are formed. figure 2 As can be seen in FIG. 1 , the synchronizing ring 7 has a total of three indexing cams 9 distributed equidistantly around the periphery and a total of six centering surfaces 10 . Each indexing cam 9 has two stop surfaces 11 , 12 pointing in the circumferential direction. At a distance therefrom, between the two stop surfaces 11 , 12 , the respective indexing cam 9 has an approximately U-shaped recess 13 . Behind this lies the consideration that the region of the recess 13 has no effect on the function of the indexing cam 9 . If conventional indexing bumps, such as figure 1 The indexing cam 3 shown in FIG. 1 is of approximately square design, the indexing cam 9 has a U-shaped recess 13 , without thereby affecting the function of the synchronizing ring 7 . It is known that it is essential for the functi...

Abstract

The invention relates to a synchronizing ring (7, 17, 20) having a base body (8) on which radially outwardly extending indexing lugs (9) and centering surfaces ( 10), characterized in that at least one indexing lug (9) has a recess (13) at a distance from the stop surface (11, 12) directed in the circumferential direction; and / or at least one fixed The centering surface (10) extends only in defined sections (19, 21) in the circumferential direction and the regions (14, 15) which are connected to said centering surface in the circumferential direction have a greater thickness than the centering surface (10) small diameter.

Description

technical field [0001] The invention relates to a synchronizing ring having a base body on which radially outwardly extending indexing cams and centering surfaces are formed. Background technique [0002] Synchronizing rings are part of the synchronization of the transmission and serve to compensate for rotational speed differences between the shaft and the escape wheel to be shifted. In addition to the synchronizing ring, the synchronizing device can also have other components, such as sliding sleeves, sleeve holders and escape wheels or idler wheels. [0003] A synchronizer ring of the same type is known from DE 10 2005 035 941 B3. According to a preferred production method, the synchronizer ring is produced from a brass alloy by forging and / or deformation from a hot solid blank. [0004] figure 1 A conventional synchronizer ring 1 is shown with a base body 2 on which radially outwardly extending indexing cams 3 and centering surfaces 4 are formed. Furthermore, the syn...
