Abstract: A dog clutch comprising a sleeve and a relative crown with respective teeth conformed for engaging each one alternatively to the others wherein, during operation a pulling side for said teeth is defined, that identifies a surface through which the torque is transferred, and wherein, the teeth pulling side or at least the crown and/or the sleeve is conformed so that the relative tooth is tapered from a relative base towards a relative vertex, wherein said pulling side comprises at least three portions of which a first portion is adjacent to said base and a third portion is adjacent to said vertex following a rectilinear path and being approximately parallel to generating line of said crown or sleeve, and having a second portion adjoining said first portion with said third portion.
