Embodiment Construction

[0036] figure 1 A coupling body 1 for a synchronization device of a motor vehicle is shown. The coupling body 1 has a substantially ring-shaped base body 3 which is produced by punching out of a plate. A coupling toothing 7 is formed on the outer circumference 5 of the base body 3, and the teeth 9 of the coupling toothing have an apex angle 11. The coupling toothing 7 is molded onto the base body 3 and, in the installed state of the coupling body, serves to engage the toothing of the moving sleeve during the shifting process.

[0037] A surrounding collar 17 divided into three subsections 15 is formed on the inner circumference 13 of the base body 3. The subsections 15 of the collar 17 are separated from one another by a window-shaped cutout 19. In the installed state of the coupling body 1, the retaining elements of the synchronization intermediate ring, such as the driven projection or the driven pawl, engage in the recess 19, thereby ensuring that the synchronization interme...

Abstract

The invention relates to a coupling body (1, 31) for a synchronisation device of a motor vehicle, comprising a substantially annular main body (3, 33), coupling teeth (7, 37) formed on the outer circumference (5) of the main body (3, 33), and a collar (17, 37), which extends circumferentially along the inner circumference (13, 35) of the main body (3, 33) and is divided into partial segments (15, 39). The partial segments (15, 39) are axially offset at the respective end segments (21, 43) thereof in order to define the axial position of an intermediate synchronising ring of the synchronisation device. The invention further relates to a method for producing a coupling body (1, 31) for a synchronisation device of a motor vehicle.

Description

Technical field [0001] The present invention relates to a coupling body for a synchronization device of a motor vehicle. The coupling body has a substantially annular base body, a coupling tooth portion formed on the outer circumference of the base body, and an inner circumference surrounding the base body , Divided into sub-sections. [0002] Furthermore, the invention relates to a method for manufacturing a coupling body for a synchronization device of a motor vehicle. Background technique [0003] Coupling bodies are usually used in synchronizing devices for shifting transmissions of motor vehicles, where the synchronizing devices are used to compensate for different shafts between the free wheel to be shifted and the shift element fixed on the shaft, the so-called synchronizing body Rotating speed. Here, the coupling body is arranged between the free wheel and the synchronizing body and serves to transmit torque from the shift sleeve to the free wheel. [0004] In order to com...
