The composite cab mount according to the present invention is composed of a first annular liquid chamber and a second annular liquid chamber, each of which has an annular liquid chamber surrounding the outer periphery of a tube and is partitioned by a funnel-shaped intermediate fitting. A gap is provided between the tubular part of the funnel-shaped intermediate fitting and the tube into which the tubular part is loosely fitted, and the viscous fluid passes through the gap to the first and second tubes.
The annular liquid chambers are configured to allow mutual communication between the annular liquid chambers.
以下、本考案の一実施例について添付図面を参

れている。 As shown in FIG. 1, the composite cab mount includes a cab-side vulcanized molded part 1, a frame-side vulcanized molded part 2, and a funnel-shaped intermediate fitting 3 that partitions the annular liquid chamber into two liquid chambers 5 and 6. The cab-side vulcanized molded part 1 is formed from an iron plate 1E facing an iron plate 1B welded to a tube 1A, and a vulcanized rubber 1C joined between these two iron plates 1B and 1E. An iron plate 1D is bonded to the center of the vulcanized rubber 1C to prevent it from swelling.

ＢをＣリング８により固定する。 When assembling the composite cab mount, first insert the intermediate fitting 3 into the vulcanized molded part 1, then press fit the frame side vulcanized molded part 2 through its vulcanized rubber part 2B, and then insert the iron plate 1E, 2A are joined together by spot welding etc., and the vulcanized rubber part 2
B is fixed with a C ring 8.

成形部品１が上方に力を受ける場合にも同様にし
てダンパ効果が得られる。 In such a configuration, when the frame-side vulcanized molded part 2 is fixed and the cab-side vulcanized molded part 1 receives a downward force, the volume of the liquid chamber 5 decreases, and the volume corresponding to that volume decreases. The liquid passes through the orifice formed by the gap 4 and moves to the liquid chamber 6, and the viscous resistance at this time provides a damper effect.
A damper effect is similarly obtained when the molded part 1 is subjected to an upward force.

As explained above, according to the composite cab mount according to the present invention, there is a gap between the tubular part of the funnel-shaped intermediate fitting that partitions the annular liquid chamber into two liquid chambers and the tube into which the tubular part is loosely fitted. By removing the intervening sealing rubber, this newly obtained gap is formed in the orifice, which eliminates the need for special machining for orifice drilling, which was previously required. There is an advantage that rubber filling can be omitted.
