Embodiment Construction

[0048] Below in conjunction with example the present invention is described in detail.

[0049] The invention is a vehicle height adjusting device based on an oil-pneumatic spring, which can be applied to all vehicles based on an oil-pneumatic spring, and realizes arbitrary height adjustment of the vehicle height within a certain range.

[0050] The vehicle height adjustment method of the present invention is formed by adding a lock valve, an oil filling and discharging valve, a high-pressure oil pump and a fuel tank to a general vehicle suspension system based on an oil-pneumatic spring, and the vehicle height can be adjusted at any height through the vehicle height adjustment device. The oil-gas spring is composed of an oil cylinder and an air cylinder, and a spring lock valve 15 is arranged between the oil cylinder and the cylinder. The amount is realized jointly by the upper cross arm 2, the lower cross arm 3 and the limiting device.

Abstract

The invention provides a device and a method for adjusting the vehicle height based on a hydro-pneumatic spring, belonging to the field of adjustment of the characteristics of a spring or a vibration damper and adjustment of the distance between a vehicle support surface and a spring suspension frame part. The device can be used for optionally adjusting the vehicle height in a set range, and contributes to remarkably improving the severe road surface passing performance, traveling stability, air drop and air transport adaptability and landmine protection performance of a vehicle. The adjusting device comprises the hydro-pneumatic spring, an upper transverse arm, a lower transverse arm, an upper limit, a lower limit, a locking valve, an oil filling/discharging valve, an oil tank and a high-pressure oil pump. The vehicle height is optionally adjusted by quantitatively filling high-pressure oil into the hydro-pneumatic spring. The adjusting device is used without changing the existing vehicle structure and influencing the vehicle performance, has low cost, is convenient for installing and adjusting the vehicle height, and has reliable safety performance.

Description

technical field [0001] The invention belongs to the field of adjusting the characteristics of springs or shock absorbers, and adjusting the distance between a vehicle support surface and a spring suspension part, and in particular relates to a vehicle height adjustment device and method based on an oil-gas spring. Background technique [0002] A typical wheeled vehicle running device is composed of wheels, a suspension system guide mechanism, elastic elements, damping elements and suspension upper and lower limit devices. For motor vehicles equipped with ordinary suspension systems, the height of the vehicle body cannot be adjusted according to the load change. Therefore, the large-scale and frequent changes in the vehicle load will aggravate tire wear and increase tire rolling resistance. At the same time, changes in vehicle body posture It will increase the air resistance, affect the stability of vehicle operation, and increase fuel consumption; the change of vehicle body ...
