Problems solved by technology

[0006] It has been proven that the end of the outer cone of the clutch body is mechanically weakened due to the presence of radially extending orifices in the end face of the outer cone
There is thus the risk that cracks can develop on the outer cone of the clutch body due to thermal stress

Embodiment Construction

[0043] figure 1 and 2 A possible implementation form of a clutch body for a synchronizing device proposed by the present invention is shown in ; Figures 3 to 10 Different embodiments of the synchronization ring proposed by the invention for the synchronization device are represented.

[0044] Figure 7 The synchronizing device shown only partially in is generally used for synchronizing idler gears on a shaft of a motor vehicle gearbox and comprises at least one synchronizing ring 8 and at least one clutch body 1 . The clutch body 1 is positively connected via the toothing 2 to an idler gear of a shaft (not shown in detail), which is to be synchronized. The synchronizer ring 8 , irrespective of its chosen embodiment, can be positively connected to a coupling sleeve, which in turn is connected to the shaft of the motor vehicle gearbox via a synchronizer body 15 in a rotationally fixed manner. In order to synchronize the idler gears, the synchronizing ring 8 is frictionally ...

Abstract

The invention proposes a clutch body (1) for a synchronization device having an annular base body (3), on which an outer cone (4) is integrally formed, the friction surface (19) of which comprises a plurality of axially extending grooves for oil distribution, wherein the outer cone (4) has a radially inside peripheral oil collection groove (6), and wherein the outer cone (4) has at least one recess (7) on the face side in the radial direction, the recess connecting the oil collection groove (6) to an associated axially extending groove for supplying oil. Furthermore, a synchronizer ring (8) of a synchronization device having an annular base body (10) is proposed, on which an inner cone (11) is integrally formed. According to the invention, predefined patterns are provided on the friction lining (9) and / or the inner cone (11). In addition, also a synchronization device comprising the clutch body (1) according to the invention and the synchronizer ring (8) according to the invention is proposed.

Description

technical field [0001] The invention relates to a synchronizing ring and a synchronizing device comprising such a synchronizing ring. Background technique [0002] From the automobile manufacturing process, all know the synchronizing device used for the synchronization of the idler gear (Losrad) on a shaft of the automobile transmission gear device. In general, a synchronizing device comprises at least one synchronizing ring and at least one clutch body. The clutch is positively connected with the idler gear to be synchronized. The synchronizing ring can be positively connected to a connecting sleeve, which is in turn connected to the shaft of the vehicle gear unit in a rotationally fixed manner via a synchronizer body. For synchronizing the idler gears, the synchronizing ring is frictionally connected to the clutch body. [0003] The friction surfaces of the synchronizing ring and the clutch body which rub against each other during the synchronization process are heated ...
