Description

【特許請求の範囲】
【請求項１】車体側と各車輪側との間に介装された、リザーバを有する油圧緩衝器と、左右車輪または前後車輪に対応する二つの油圧緩衝器内のピストン下室またはピストン上室に各独立の管路にて接続された蓄圧室を有するアキュムレータと、前記二つの油圧緩衝器の圧力をパイロット圧として弁要素に受け、その圧力差により弁要素を作動させて前記二つの管路を選択的に開閉する切換弁とを備え、前記切換弁は、前記パイロット圧を導入する各パイロット流路に絞りを設けていることを特徴とする車両用懸架装置。 [Claims]
1. A hydraulic accumulator having a reservoir, which is interposed between the vehicle body side and each wheel side, and a lower piston chamber or an upper piston chamber in two hydraulic accumulators corresponding to the left and right wheels or the front and rear wheels. in the accumulators to have a connected accumulator at each independent of the conduit, under pressure of the two hydraulic shock absorber on the valve element as the pilot pressure, the two actuates the valve element by the pressure differential A vehicle suspension device including a switching valve that selectively opens and closes a pipeline, and the switching valve is provided with a throttle in each pilot flow path into which the pilot pressure is introduced.

[Means for solving problems]
In order to achieve the above object, the present invention presents a hydraulic accumulator having a reservoir, which is interposed between the vehicle body side and each wheel side, and a piston in two hydraulic accumulators corresponding to the left and right wheels or the front and rear wheels. and accumulators that have a pressure accumulating chamber connected at each independent of the conduit to the lower chamber or the upper piston chamber, under pressure of the two hydraulic shock absorber on the valve element as the pilot pressure, the valve element by the pressure differential The switching valve is provided with a switching valve that is operated to selectively open and close the two pipelines, and the switching valve is characterized in that a throttle is provided in each pilot flow path into which the pilot pressure is introduced.
