Abstract

A torque transmission arrangement in a motor vehicle drive train, having a radially inner shaft and a radially outer hub, which are joined together in torque-transmitting manner by a plug-in toothed gearing with play, in which the plug-in gearing, and shaft outer teeth cooperate with hub inner teeth. In order to avoid gear teeth clattering, and to provide a freedom from play in the plug-in gearing, a spring element is provided, with which the shaft and can be braced against each other. In order to produce the freedom from play, the hub includes a support portion against which the spring element is supported with a spring force, building up a tilting moment by which the hub can tilt with respect to the shaft in the axial direction.

Claims8

Dependent claims

A torque transmission arrangement in a motor vehicle drive train, comprising:

a radially inner shaft having outer teeth;
a radially outer hub having inner teeth and an annular support portion comprising an inwardly-facing cylindrical surface adjoining the inner teeth in an axial direction;
wherein the shaft outer teeth cooperate with hub inner teeth in a torque-transmitting manner with play, and wherein an annular space is formed between the shaft outer teeth and hub support portion;
and
a spring element provided within the annular space of the hub support portion, with which the shaft and the hub can be braced against each other in order to avoid gear teeth clattering and to prevent play in the gearing between the inner and outer teeth, the spring element comprising a band-shaped spring washer body having at least one radially-inwardly projecting indentation engaging a tooth gap of the shaft outer teeth, and a resilient radially-outwardly projecting protrusion comprising a spring tongue cut-out from the spring washer body;
wherein in order to prevent play in the gearing, the protrusion is supported with a spring force against the hub support portion, building up a tilting moment by which the hub can tilt with respect to the shaft in the axial direction.
