摘要： A suspension device for suspension of an axle 2 by an intermediate portion of a single leaf spring 5 has first restriction means which restricts, upon breakage of the leaf spring 5 at a position behind the intermediate portion of the spring, the rear portion of the leaf spring 5 from tilting downwardly relative to a shackle 6, and a second restriction means (retainer pawl 13) for restriction of the shackle 6 from pivotally moving backward beyond a predetermined angle. The first restriction means is constituted by a stopper plate 12 (stopper) on the shackle 6 for support of the rear portion of the leaf spring 5 from below upon breakage.

摘要： Leaf springs have improved durability in spite of using inexpensive spring steel such as SUP9 and SUP11 as materials. While a spring main body, made of the spring steel in which Brinell hardness is under 555 HBW and not less than 388 HBW (corresponding to a diameter of under 2.70 mm of hardness and not less than 3.10mm of hardness on a Brinell ball mark), is maintained at 150 to 400° C., the load is applied in the direction in which the spring main body is to be used, and the first shotpeening is performed at the plane where the tensile stress acts.

摘要： An accumulator comprises a housing and a rod. The housing is sealed by means of high- and low-pressure sealing devices. The high-pressure sealing device includes an annular groove formed on the inner surface of the housing, a seal ring with an L-shaped section housed in the annular groove, and an elastomeric O-ring disposed on the outer periphery side of the seal ring. The seal ring is composed of a thin wall portion, situated on the high-pressure side, and a thick wall portion situated on the low-pressure-side. The inner peripheral surface of the thick wall portion is in contact with the outer peripheral surface of the rod. A gap, which is wide enough to receive the hydraulic fluid, is defined between the inner peripheral surface of the thin wall portion and the outer peripheral surface of the rod. A drain recovery hole is connected between the high- and low-pressure sealing devices.
