Abstract

[Problem] To provide a solenoid-type variable damper that improves piston strength and prevents disconnection of the electromagnetic coil, and the like. [Solution] A piston (16) comprises a piston body (30), an expansion-side valve plate (41), a contraction-side valve plate (42), an electromagnetic coil (43), and a bolt (44). The piston body (30) is cast as a single piece and is manufactured through a powder metallurgy method, a die casting method, or the like, using a ferrite-based or other ferromagnetic material as a raw material, and comprises a cylindrical outer yoke (31) that is in slidable contact with the inner periphery of a cylinder (12); a columnar inner yoke (34), the outer periphery of which faces the inner periphery of the outer yoke (31) across first and second gaps (32, 33); and a connecting section (35) in the central part in the axial direction of the piston (16), which connects the outer yoke (31) and the inner yoke (34) and divides the first and second gaps (32, 33) from each other. The electromagnetic coil (43) is fit into the second gap (33) of the piston body (30).

Description

technical field [0001] The present invention relates to a solenoid type variable damping force damper used in the suspension of a vehicle, and in particular to a technique for improving piston strength and preventing wire breakage in an electromagnetic coil. Background technique [0002] Suspension is an important factor that significantly affects the running stability of a vehicle, and typically includes, as its main components, links (eg, arms, rods, etc.), springs, and dampers, which support wheels so as to be vertically movable relative to the vehicle , the spring is flexible to absorb the impact from the road surface or the like, and the damper is used to damp the oscillation of the spring. Such a damper of a vehicle suspension is generally embodied as a tubular damper comprising a hollow cylinder filled with hydraulic oil, a piston configured to slide in the axial direction within the cylinder and a piston rod having an end connected to the piston, Where hydraulic oil...
