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

[0044] figure 1 with 2 A feasible implementation form of a clutch body for a synchronizing device proposed by the present invention is shown in FIG. Figure 3 to 10 Shows the different implementation forms of the synchronization ring for the synchronization device proposed by the present invention.

[0045] Figure 7 The synchronizing device shown only partially in is usually used for synchronizing an idler gear on one shaft of an automobile gearbox, and it includes 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 synchronizing ring 8, regardless of the selected embodiment, can be connected in a form-locking manner to a connecting sleeve, which in turn is connected to the shaft of the automobile gearbox via a synchronizing body 15 in a rotationally fixed manner. In order to synchronize the idler gear, the synchronizing r...

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 present invention relates to a clutch body, a synchronizing ring and a synchronizing device of the type defined in detail in the preambles of claims 1, 5, 14, 19 and 27, respectively. Background technique [0002] From the automotive manufacturing process, we all know the synchronization device used for the synchronization of the idle gear (Losrad) on one shaft of the automobile transmission gear device. Generally speaking, the synchronizing device includes at least one synchronizing ring and at least one clutch body. The clutch body is connected in a form-locking manner with the idler gear to be synchronized. The synchronizing ring can be connected to a connecting sleeve in a form-locking manner, and the connecting sleeve is connected to the shaft of the automobile transmission gear through a synchronizer body in a rotationally fixed manner. In order to realize the synchronization of the idler gear, the synchronizing ring is frictionally connected wi...
