摘要： PURPOSE:To simplify a power source by providing a selector valve selectively connected to either a working fluid supply means cylinder mechanism or an actuator. CONSTITUTION:When load applied to a cab 5 is increased and the length of an actuator 10 becomes less than a designated value, in response to an output signal of detecting means 35, a selector valve 45 is switched to a position for supplying oil to the actuator 10, that is, in the direction of elongating a rod 16. On the contrary, when load applied to the can 5 is decreased, the selector valve 45 is switched to a position for some of oil from the actuator 10, that is, in the direction of contracting the rod 16. When the cab 5 reaches a designated height, according to an output signal sent from detecting means 35, the selector valve 45 is returned to the neutral position. By this arrangement, it is not necessary to provide a driving power source special for the actuator 10.

摘要： PURPOSE:To prevent an inner seal from being damaged and prevent oil and gas from leaking by installing said inner seal which seals a part between a cylinder and a hollow rod which is inserted in said cylinder, in a position in which said hollow rod does not get out of said cylinder even when it extended at its maximum. CONSTITUTION:The suspension system of a car consists of a main actuator 1 and a sub-actuator 50. In the main actuator 1, a hollow rod 8 in which an oil chamber 9 and a gas chamber 10 are provided, is inserted, extensibly and rotatably, into a cylinder 2 in which an oil chamber 5 is provided. And, an inner seal 44 which seals a part between the cylinder 2 and the hollow rod 8, is provided in the axial middle part of the inner wall of the cylinder 2. In this case, the inner seal 44 is installed in a position in which the sliding area of the outer periphery of the hollow rod 8 which is in contact with the inner seal 44, does not get out of the cylinder 2 even when the hollow rod 8 is extended at its maximum. Thereby, said sliding area can be prevented from being exposed to the air, attaining the desired end.

摘要： PURPOSE:To prevent the increase of the sliding resistance by allowing a number of floating particles having the smaller specific gravity than that of oil to cover the oil surface, onto the boundary surface between oil and gas in a hollow rod installed into a cylinder and by separating gas from oil. CONSTITUTION:The spring function due to the repulsive force of gas is developed by the extension and contraction of a hollow rod 8, and the damping function is developed by the flow of oil in a damping-force generating mechanism 11. Since, at this time, the particles having the specific gravity smaller than that of the oil float on the boundary surface of oil and gas, dissolution and mixing of gas and oil are prevented, even if the vertical movement of the oil level position which is accompanied by the extension and contraction of the hollow rod 8 exists. With such constitution, the outside leak of gas from a sealing part 5 is prevented, and reliability can be improved.

摘要： PURPOSE:To collect the gas leakage from a sealing section and prevent gas from being leaked externally by forming a sub-gas chamber between a gas cham ber outer cylinder provided at the outside of a hollow rod and the hollow rod and connecting the sub-gas chamber to a main gas chamber. CONSTITUTION:A hollow rod 8 is inserted in a cylinder 1 so as to freely slide and a damping force generation mechanism 12 is provided at the lower part of the rod 8 between hydraulic pressure 2 and 9. In addition, a gas chamber outer cylinder 35 is concentrically provided at the outside of the rod 8 and a sub-gas chamber 36 is formed between the gas chamber outer cylinder 35 and the rod 8. This sub-gas chamber 36 is connected to a main gas chamber 10 through a gas path 22 and a switching valve 21. Thus, even if the gas dissolved in oil is escaped from a sealing section 6, this gas is collected in the sub-gas chamber 36 and is not leaked externally. Besides, since the gas pressure of the sub-gas chamber 36 is applied to the sealing section 6 and the differential pressure of the sealing section 6 is small, a suspension unit with low pressure resistance is required.
摘要翻译：目的：从密封部分收集气体泄漏，通过在设置在中空杆外侧的气罐外筒与中空杆之间形成副气室，并将副气体室到主气室。构成：中空杆8插入气缸1中以便自由滑动，并且在液压压力2和9之间在杆8的下部设置阻尼力产生机构12.此外，气室外筒35 同心地设置在杆8的外侧，并且在气体室外筒35和杆8之间形成副气室36.该副气室36通过气路22与主气室10连接因此，即使溶解在油中的气体从密封部6逸出，该气体被收集在副气室36中，也不会从外部泄漏。此外，由于副气体室36的气体压力被施加到密封部分6，并且密封部分6的压差很小，因此需要具有低耐压性的悬架单元。

摘要： PURPOSE:To improve reliability in a lockup of bump rubber without using any extra parts in addition, by stopping an axial movement of the bump rubber in utilizing burrs produced in time of frictionally pressure-welding an end member to an inner cylinder. CONSTITUTION:An inner cylinder 11 is inserted into an outer cylinder 10 free of motion in its axial direction, while a metallic end member 12 is locked up so as to close an opening part at the upper end side. This end member 12 is designed so as to be attached to an end face of the inner cylinder 11, and after frictional pressure welding is carried out, some burrs 13 are left behind there, and these burrs 13 are continuously projected in the circumferential direction of a pressure- welding part. In addition, bump rubber 14 consisting of an elastic body of rubber or the like is set up in a position situated at an upper end part of the inner cylinder 11 whereby a part 14a of an inner surface of the bump rubber 14 is engaged with these burrs 13. With this constitution, reliability in an axial lockup of the bump rubber is thus improvable.

摘要： PURPOSE:To allow change in spring constant and damping force for better travelling comfort and stability by interconnecting gas chambers of main and auxiliary actuators through a gas passage and providing in the gas passage a switch valve whose opening and closing can be controlled. CONSTITUTION:A main actuator 1 includes a cylinder 3 having inside thereof an oil chamber 5 and at the lowermost end thereof a fixture 4 for attaching the actuator to an axle. An auxiliary actuator 2 is divided by a free piston 30 into an oil chamber 31 and a gas chamber 32. The gas chamber 32 and the gas chamber 12 of the main actuator 1 are interconnected through a gas passage 33 and, a switch valve 34 is provided in the gas passage. At normal straight driving on a smooth road, the valve 34 is open, allowing communication between the gas chambers 12, 13 to lower the spring constant, and an orifice 19 for adjusting damping force is open to reduce the damping force for improved travelling comfort. At turning or others, the valve 34 is closed to raise the spring constant, and the orifice 19 is closed to increase the damping force for better stability of the vehicle body posture.

摘要： PURPOSE:To restrict generation of damping force in response to small vibrations for better travelling comfort by providing in a hollow rod a valve body having an orifice serving to complete communication between an oil chamber in a cylinder and an oil chamber in the hollow rod. CONSTITUTION:A hydraulic pneumatic actuator 1 includes a cylinder 3 having at the lowermost end thereof a fixture 4 for attaching the actuator 1 to a part on the axle side and inside thereof an oil chamber 5. The cylinder 3 accomodates a hollow rod 8, and the inside of the hollow rod 8 is transversely divided by a free piston 11 into an upper gas chamber 12 and a lower oil chamber 13. The oil chamber 13 communicates with the oil chamber 5 through an orifice 15 of a valve body 16 provided in piston means 14. Thus constructed, compression of the rod 8 causes only movement of the valve body 16 and no flow of oil through the orifice, no damping force produced to prevent transmission of shocks at riding on small projections on the road surface for improved travelling comfort.
