ABSTRACT:
A brake mechanism, applicable to the braking of trailer vehicles, has an electro-magnetic arrangement which is disposed between the inner ends of coaxial wheel supporting shaft units to selectively and individually control the rotation thereof. Each shaft unit has a gearing arrangement for transmitting the braking action to the wheels. Oil is circulated between the spaces of the stationary and moving parts of each shaft unit. And the production of air pressures from heat generated by the functioning of the units is eliminated.
