Title:
SUSPENSION DEVICE FOR AUTOMOBILE
Document Type and Number:
Japanese Patent JPS62251219
Kind Code:
A
Abstract:
PURPOSE:To absorb a high frequency vibration through the flowing in and out of a fluid via an orifice by providing a buffering body in between the top end part of a coil spring which absorbs vibration transmitted from a wheel and a body side member and partitioning the fluid chamber of said buffering body into two chambers by means of a partition wall on which said orifice is formed. CONSTITUTION:A damper 6 and a coil spring 7 are provided in between an axle casing 2 as a wheel side member and a body side member, to absorb the vibration of the wheel 1. In such a device, the top end 7b of the coil spring 7 is supported by a floor panel 12 as a body side member via an upper seat 13 and a buffering body 14. And, a fluid chamber 16 is provided inside the buffering body 14, and is partitioned into two chambers 16a, 16b by a partition wall 18, while an orifice 18a is formed on the partition wall 18 to connect the two chambers 16a, 16b. Thereby, a high frequency vibration which is transmitted to the buffering body 14 through the coil spring 7 can be absorbed by the flowing in and out of a fluid via the orifice 18a.
