Abstract
The invention relates to a synchronizer clutch (,) comprising a sliding sleeve (,) with selector teeth (,), two synchronizing rings (,) with locking teeth (,) and friction surfaces (,) situated on both sides of the sliding sleeve (,) and rotatable around a limited rotation angle, and two clutch bodies (,) with coupling teeth (,) and counter friction surfaces (,) interacting with the synchronizing rings (,) wherein the sliding sleeve (,) is constantly connected with a transmission element (,) by a sleeve guide (,) so as to be torsionally resistant and, when engaged, is connected with one of the clutch bodies (,) with positive fit by the selector teeth (,) and the coupling teeth (,). In order to prevent that the selector teeth (,) of the sliding sleeve (,) come into contact with the coupling teeth (,) unhindered when changing gears and causing noise, the synchronizing rings (,) are coupled with each other in a way such that when one side is engaged, the locking teeth (,) of the synchronizing ring (,) on the non-engaged side are in locked position.
