Embodiment Construction

[0014] The present invention will be described in further detail in conjunction with the following examples (accompanying drawings):

[0015] as attached figure 1 As shown, the oil-gas spring suspension oil cylinder of the present invention is mainly composed of an upper coupling body 1, a damping hole 2, a main piston 3, a cylinder barrel 4, a piston rod 6, a guide sleeve 7, a large nut 8, a lower coupling body 9, a lower seat 10, The cylinder 12, the floating piston 13, the seal ring 15, the upper seat 16 and the one-way valve 17 are composed, wherein the piston rod 6 is a hollow structure, and a guide sleeve 7 is arranged on the outside of the hollow piston rod. Four spaces, main oil chamber 18, auxiliary oil chamber 11, piston rod chamber oil chamber 5 and air chamber 14, are formed inside the oil cylinder.

[0016] The main oil chamber 18 is a space surrounded by the main piston 3, the cylinder barrel 4 and the upper coupling body 1. The main piston 3 is provided with a ...

Abstract

The invention relates to a hydro-pneumatic spring suspension cylinder which mainly comprises an upper connector 1, a damping hole 2, a main piston 3, a cylinder barrel 4, a piston rod 6, a guide sleeve 7, a large nut 8, a lower connector 9, a lower seat 10, a cylinder 12, a floating piston 13, a sealing ring 15, an upper seat 16 and a one-way valve 17, wherein the piston rod 6 is of a hollow structure, and the guide sleeve 7 is arranged outside the hollow piston rod. A main oil chamber 18, an auxiliary oil chamber 11, a piston rod cavity oil chamber 5 and an air chamber 14 are formed inside the cylinder. The upper connector of the hydro-pneumatic spring suspension cylinder is connected with a frame, the lower connector is connected with an axle, an engineering vehicle can realize a wide-range lifting function, vibration reduction requirements under a severe road condition in the running process can be met, working condition adaptability and running smoothness of the vehicle are improved, and comfort of drivers and passengers is improved.

Description

technical field [0001] The invention relates to an oil-pneumatic spring suspension oil cylinder, in particular to an oil-pneumatic spring suspension oil cylinder for engineering vehicles, which can realize the large-scale lifting function of the engineering vehicle and meet the requirements of vibration reduction under severe road conditions during driving. Background technique [0002] Although some existing oil-pneumatic springs for construction vehicles have a certain damping effect, they cannot take into account the two different operating conditions of no-load and full-load. Some oil and gas springs require large accumulators and need to be designed as external, which often leads to difficulties in vehicle layout, resulting in complex structures and increased manufacturing costs. Therefore existing oil-pneumatic springs can't meet the requirements of large-scale lift function and harsh road vibration reduction for vehicles, and the driver's handling stability and drivin...
