摘要:
A torque detector (16) is provided with first and second units (38, 39) . The first unit (38) includes a first synthetic resin (40) formed by molding a pair of magnetic flux collector rings (34A, 34B). The second unit (39) includes a second synthetic resin (41) fixed to a magnetic shield plate (37B) containing a metal; an insertion protruding part (44) arranged on the synthetic resin (41); and magnetic sensors (35A, 35B) held by the insertion protruding part (44). The first synthetic resin (40) includes a receiving plate (38a) whereupon a base (38e) for receiving the magnetic shield plate (37B) is formed. In a status where the receiving plate (38a) exists between the magnetic shield plate (37B) and an object (30) to be attached, both the magnetic shield plate (37B) and the receiving plate (38a) are fastened to the object (30) by a pair of fixing screws (32) .
摘要:
An electric power steering apparatus 1 comprises a charge-discharge circuit 25 capable of configuring a circuit for charging an auxiliary power supply 7 and a circuit for discharging a battery 6 and the auxiliary power supply 7 as well as configuring a discharge-preference circuit which enables only the discharge of the auxiliary power supply 7 while avoiding the charge thereof. In the apparatus, a control circuit 20 performs a power latch operation of carrying on control till the end of a predetermined period of time following an operation of turning off an ignition key 23, and also causes the charge-discharge circuit 25 to configure the discharge-preference circuit thereby enabling steering assist accompanied by the discharge of the auxiliary power supply 7.
