ABSTRACT:
The invention relates to a synchronizing arrangement for a motor vehicle gear box, comprising at least one synchronizing hub disposed locationally fixed in the longitudinal direction on a shaft, which hub co-acts via external teeth with internal teeth on a concentric synchronizing sleeve which is arranged so that it may be displaced in the axial direction.
The invention is characterized in that the hub is formed with teeth which have a different tooth shaping in a lower and in an upper part of the tooth respectively, in that the tooth shaping in the upper tooth part is wider than an extension of the tooth shaping in the lower tooth part up to the maximum diameter of the hub, in that the tooth shaping in the upper parts of the teeth is able to fit into the grooves between the teeth on the sleeve, in that the lower parts of the teeth have a greater axial length than the upper parts of the teeth, and in that the teeth on the sleeve co-act, when torque is transmitted, with the lower parts of the teeth on the hub, so that a tooth flank in the upper part of the teeth occupies a position outside the profile of the tooth grooves on the sleeve and thereby prevents the axial displacement of the sleeve into engagement with the upper tooth parts on the hub.
The arrangement of the invention enables the synchronizing hub and sleeve to be manufactured relatively simply and cheaply.
