Filed: 1993-11-24
Abstract: PURPOSE:To increase magnetic flux density on an attraction surface, by changing the material of a permanent magnet, within the restriction range of dimension, and changing the constitution of magnetic circuit of an attraction jig. CONSTITUTION:An attraction part 5 is constituted by forming a recessed part of a cylinder type having a bottom on the end portion side surface of a nonmagnetic housing 4. In the attraction part 5, a rectangular parallelopiped permanent magnet 6 of rare earth is clamped in the magnetization direction by two semi-circular cylinder type soft magnetic members 7 wherein recessed parts are formed on the attraction surface side, and a magnetic circuit is formed. Thereby the bottom surface is easily worked flatly, and a gap is not generated between the permanent magnet and the bottom surface. The leakage magnetic flux of the magnetic circuit which clamps the rectangular parallelopiped permanent magnet in the magnetization direction by the semi-circular cylindrical soft magnetic members is smaller, so that a magnetic field can be effectively generated.

Title: Stabilizer device for vehicle
Inventor: NAKAMURA KOJI
IPC: B60G17/015
Filed: 1990-11-27
Abstract: PURPOSE:To improve riding comfort and control stability as well by using a direct operational type electromagnetic actuator as a connecting mechanism connecting a stabilizer main body to the mounting sections of a body and the like, providing both a power supplying means to the coil of the mechanism and a power consuming means for power generated, and thereby enabling the reaction of the stabilizer to be regulated. CONSTITUTION:Electromotive force is generated by a coil 45 when moving members 15 and 22 are relatively moved as the arm of a stabilizer main body is displaced at the time of passing through the irregularities of the surface of a road. Energy thus produced is discharged to a radiator 56, so that damping force is thereby produced by an electromagnetic actuator 46 while the displacement is being absorbed. In this case, when amperage to the radiator 56 is controlled by a current control section 55, damping force is changed so as to be controlled in a stepless manner from free movement. In addition, current is supplied to the electromagnetic actuator 46 from a power supply circuit 53 at the time of high speed cornering, so that roll control is thereby assumed with the movement of the moving members 15 and 22 controlled.
