PLATE THAT HAS A VENTILATION CHANNEL

Abstract

The present invention relates to a plate (10) for use in a transmission element that provides motion transfer between the engine and the gearbox in motor vehicles, the object plate (10) comprising an annular body (101) with a rotation axis (X) bounded by a cylindrical inner wall (11) and a cylindrical outer wall (12), and a friction surface (13) and at least one ventilation channel (20) extending radially from said cylindrical inner wall (11) to the cylindrical outer wall (12); as an improvement, an axial channel height (H), defined between a first wall (21) of said ventilation channel (20) and a second wall (22) of the ventilation channel (20) arranged axially opposite the first (21), is provided in a form that first widens and then narrows from the cylindrical inner wall (11) to the cylindrical outer wall (12).
