Embodiment Construction

[0032] The same components in the embodiments of the drawings use the same reference symbols below.

[0033] figure 1A schematic illustration of the assembly unit 1 is shown in cross section. The assembly unit 1 has a synchronizing carrier body 3 held together axially by a fastening clip 13 , three presynchronizing elements 5 , a sleeve 7 and two synchronizing rings 9 , 11 . figure 1 Based on this view, only one synchronous ring 9 can be seen, and the layout scheme of the two synchronous rings 9 and 11 can be found in figure 2 . The synchronizing carrier 3 , the presynchronizing element 5 and the clutch 7 form a so-called clutch unit.

[0034] Synchronization carrier 3 can be form-locked with figure 1 is connected to a transmission shaft not shown. A presynchronizing element 5 is held between the synchronizing carrier 3 and the sleeve 7 . Each of the three presynchronizing elements 5 is made of three parts. The mentioned structure from figure 2 As can be seen. When ...

Abstract

The invention relates to assembly units (1, 51) for motor vehicle transmissions, which comprise synchronous carrier bodies (3, 53) connected to a transmission shaft extending along the axial direction, a plurality of pre-synchronizing elements (5, 55) arranged on the outer periphery (19) of the synchronous carrier bodies (3, 53), a coupling sleeve (7), outer synchronous rings (9, 11, 59) and fastening clamps (13, 61), wherein the fastening clamps (13, 61) are used for keeping all the parts gathering till the parts are safely mounted in the place of a client, so as to ensure the safety transportation and simple assembling.

Description

technical field [0001] The invention relates to an assembly unit for a vehicle transmission having a certain number of components required for the synchronization of the transmission. The assembly unit makes it easy for the customer to store and assemble the included components. Background technique [0002] An assembly unit of the type mentioned at the outset is known from DE 10 2005 040 691 A1. The system in DE 10 2005 040 691 A1 comprises a certain number of at least two synchronizing rings of a synchronizing device, which are held together by a mechanism that prevents loss of connection. In one embodiment, the synchronizing inner ring has for this purpose a strip-shaped and radially extending connecting section, on the radially outer end of which a holding section or holding body is arranged. A retaining element in the form of a radially extending hook-shaped projection is arranged in the axial end region of the retaining body. The projection extends radially to such ...
