Embodiment Construction

[0018] exist Figures 1 to 4 The synchronizing body 1 shown in is designed for a synchronizing device of a gear transmission. The synchronizing body 1 comprises a base body formed as a ring part 2 which has an external toothing 3 . The ring part 2 has an opening 4 into which the inner ring 5 is inserted in the mounted state. The inner ring 5 itself has openings 6 which enable a rotationally fixed mounting of the inner ring 5 on the transmission shaft. Ring part 2 and inner ring 5 are coupled to one another via an overrunning clutch, which is designed as a sprag freewheel. For this purpose, the inner ring 5 has on its outer side a ramp-shaped contour 7 on which two wedge disks 8 , 9 are arranged axially next to each other. exist figure 1 It can be seen that the wedge disks 8 , 9 engage on the outside into circumferential grooves 10 on the inside of the ring part 2 . The two wedge disks 8 , 9 act like the clamping bodies of a conventional freewheel.

Abstract

A synchronizing body (1) for a synchronizing mechanism of a variable-ratio gear transmission, having a ring part (2) that has outer toothing (3) and having an inner ring (5) that has an opening (4) for a gear shaft, the ring part and the inner ring being connected to each other by means of an overrunning clutch that is in the form of a wedge plate freewheel.

Description

technical field [0001] The invention relates to a synchronizing body for a synchronizing device of a gear transmission, having a ring part with external toothing and an inner ring having an opening for a transmission shaft, the ring part and the inner ring are coupled to each other via an overrunning clutch. Background technique [0002] Such a synchronizer is known from DE 11 2009 005 205 T5. A synchronizing body is a component of a synchronizing device which is installed in a manually shifted transmission in order to allow comfortable shifting between the individual gears. During the shifting process, the peripheral speed of the gear wheel is adapted to the peripheral speed of the transmission shaft by means of various elements of the synchronization device, and a form-fit connection between the gear wheel and the transmission shaft is then produced. In this case, the transmission shaft and the sliding sleeve are connected to one another in a rotationally fixed manner by...
