Abstract:
Forming a recess in an intermediate section in an axis direction of an outer peripheral face of a stabilizer bush allows the contact surface pressure between an inner peripheral face thereof and an outer peripheral face of a torsion portion to be low in a section where the recess is formed. Therefore, when the torsion portion twistedly deforms, slipping against the torsion portion starts from the intermediate section in the axis direction of the stabilizer bush, and the slipping spreads to opposite end parts in the axis direction, thus enhancing the ride comfort of a vehicle. Moreover, open ends of axially opposite end parts of the stabilizer bush, where no recess is formed, are put in intimate contact with the outer peripheral face of the torsion portion, thus preventing sand and mud from entering therefrom.

Abstract:
A fluid-filled vibroisolating device comprises a joint member adapted to be joined to a vibrating body such as an engine. A support member is adapted to be supported on a supporting body such as a vehicle frame and defining an expandable and contractible auxiliary fluid chamber filled with a fluid. An elastomeric member interconnects the joint and support members and is disposed in a vibrating direction in which the vibrating body vibrates. The elastomeric member, the joint member, and the support member jointly define an expandable and contractible main fluid chamber filled with a fluid. A partition is mounted in the support member and separates the main and auxiliary fluid chambers from each other. The partition has flow regulators for regulating the flow of the fluid between the main and auxiliary fluid chamber. A reinforcing member is integrally formed with the elastomeric member for preventing the elastomeric member from being collapsed. By selecting various parameters of the device to meet a predetermined equation, and providing as the flow regulating mechanism an orifice between the main and auxiliary fluid chambers for allowing the fluid to flow or resonate, and also a movable plate movable dependent on the difference between the fluid pressures in the main and auxiliary fluid chambers, the damping capability of the fluid-filled vibroisolating device is improved and the dynamic spring constant thereof is uniformly lowered in a wide range of frequencies.

Abstract:
A stabilizer bush (18) is fitted onto the outer peripheral face of a torsion portion (15) of a stabilizer and fixed by being clamped under pressure between a mounting portion (19a) of a vehicle body (19) and a mounting bracket (21). Since a chamfered portion (18f) that opens out radially outwardly is formed at an open end of an inner peripheral face (18d) of the stabilizer bush (18), when the stabilizer bush (18) is compressed radially inwardly, a load that is inward in an axis (L) direction is generated at the open end, thus preventing the open end from opening in a way such that it turns up. It is thereby possible to prevent sand or mud from entering between the inner peripheral face (18d) of the stabilizer bush (18) and the torsion portion (15) of the stabilizer, thus preventing the occurrence of abnormal noise or abrasion of the torsion portion.
