<p>The invention relates to a magnetic flux collector for a torque detection device. The collector includes two coaxial magnetic cylinder heads (6, 7), having respectively interlocked teeth (17, 28), overmoulded by means of a plastic material. The two cylinder heads (6, 7) have, at the periphery thereof, notches (18, 19, 23) provided such as to engage with matching grooves (32, 33) which comprise a cylindrical cavity (31) of a mould (30) for overmoulding the cylinder heads with the plastic material. The two cylinder heads (6, 7) are therefore positioned in a very accurate manner relative to one another, before injecting the overmoulding plastic material. The invention can be used for the production of torque sensors used in the power-steering systems of automobiles.</p> |
