ABSTRACT:
A dog clutch includes complementary cooperative male and female connection parts, one of which parts is defined by a hub integral with a wheel while the other part is carried by an end part of a shaft and which have such configuration as to define a series of cylindrical peripheral bearing surfaces and to provide between two successive bearing surfaces radial abutments which define therebetween projections engaged in cavities. A centrifugal expansion device is disposed directly and at least partly in the end part so as to produce a radial expansion of the series of male bearing surfaces and normally achieve an immobilization by the effect of friction of the hub on the end part, and exceptionally achieve a locking against rotation by contact of the abutments.
