Embodiment Construction

[0019] figure 1 A schematic three-dimensional schematic diagram of the disassembly of the synchronization device 1 according to the first embodiment of the present application is shown. The synchronizing device 1 has four ring-shaped components 4, 9, 11 and 12, which form a synchronizing clutch or synchronizing device 1 acting on both sides. The synchronizer housing 4 is connected to the transmission shaft in a torque-proof and axially fixed manner via a hub portion 24 having an internal toothing 27 facing the axis 23 of the transmission shaft. The synchronizer housing 4 has an external toothing portion with three openings 5, 6 and 7. The outer protrusions 13 of the synchronization rings 11 and 12 arranged on both sides of the synchronizer housing 4 are engaged with the cavities 5, 6 and 7 in a form-fitting manner.

[0020] In addition, in this embodiment of the present application, each of the synchronizer rings 11 and 12 also has an inner protrusion 14, which is in a form-fitt...

Abstract

The invention refers to a shift transmission synchronizer (1), comprising a synchronizer shell (4), a sliding sleeve (9) and at least one synchronizer ring (11,12), wherein the synchronizer shell is torsion resistant and is axially fastened to a transmission shaft, and the synchronizer shell is provided with an external tooth part (8) equipped with one or more vacant positions (5,6,7). The sliding sleeve (9) is provided with an inner tooth part (10) and can be axially and slidingly connected with a shift gear. In addition, the at least one synchronizer ring (11,12) possesses one or more axially oriented raised projections (13,14) which extend to the vacant positions (5,6,7), wherein one or more raised projections (13,14) possess radial and axial metal outside surfaces (15 to 18), and the radial metal outside surfaces (15,16) are provided with a damping coating (20).

Description

Technical field [0001] The present invention relates to a synchronization device for a shift transmission, comprising a synchronizer housing, a sliding sleeve and at least one synchronizer ring, wherein the synchronizer housing is torque-proof and the shaft is fixedly fixed on the transmission shaft, and the synchronizer The housing has an external tooth part provided with one or more vacancies. A sliding sleeve with internal teeth is axially movably arranged on the external teeth and can be coupled with the shift gear. Furthermore, the synchronization device has at least one synchronization ring with one or more axially oriented protrusions. The protrusion extends into the void. Background technique [0002] The synchronizing device of such a shift transmission is disclosed in the patent document DE 10 2006 060 534 A1, and is usually arranged on an intermediate transmission shaft in a manual or automatic shift transmission, wherein the synchronizer housing is torque-proof with...
