Problems solved by technology

However, with the increase in the requirements for vehicle capacity and the requirements for vehicle stability, safety, and comfort, especially for storage and transportation equipment with large load changes, how to ensure that the vehicle attitude adjustment speed is consistent when the vehicle is empty or fully loaded, and how to ensure that the vehicle When the body height is adjusted, especially when it is fully loaded, the top-loaded goods are stable, how to achieve high efficiency and energy saving of the system, and reduce efficiency loss have become technical difficulties that domestic vehicle manufacturers are facing and have not been able to effectively solve. Therefore, the development is based on load-sensitive The principle of modular car attitude adjustment system is particularly necessary

Embodiment Construction

[0022] The vehicle posture adjustment system is described in detail below in conjunction with the accompanying drawings:

[0023] Described vehicle attitude adjusting system is made up of hydraulic system, left one oil-pneumatic suspension 9, left two oil-pneumatic suspension 13, right one oil-pneumatic suspension 17, right two oil-pneumatic suspension 21, electric control device and cable and sensor, and between each part of hydraulic system and The hydraulic system and the oil-air suspension are connected through high-pressure hard pipes (or hoses), and the electric control device is connected with the solenoid valve group of the hydraulic system through cables to provide control signals. The hydraulic system in the present invention is divided into a load-sensitive proportional throttle valve group for a single-acting cylinder and a load-sensitive proportional throttle valve group for a double-acting cylinder according to the different action modes of the applicable oil-gas ...

Abstract

The invention relates to an energy accumulator vibration attenuation valve group with a locking function. The energy accumulator vibration attenuation valve group is formed by connecting a large-power vibration attenuation valve and a normally opened two-position two-way rigid locking valve in series and is connected in series between an energy accumulator and a hydro-pneumatic suspension cylinder, wherein the large-power vibration attenuation valve is formed by connecting three elements, namely, a forward one-direction valve, a throttle valve and a backward one-direction valve in parallel, so as to achieve the purposes of bidirectional throttle vibration attenuation, hydraulic impact reduction and water surge wave oscillation reduction. After the rigid locking valve is powered on and locked, a whole chassis form a rigid platform, so that the working stability can be improved.

Description

technical field [0001] The invention relates to an accumulator damping valve group with a locking function of an oil-gas suspension vehicle attitude adjustment system, which belongs to the application field of hydraulic machinery and motor vehicles. Background technique [0002] By adopting oil-pneumatic suspension technology, the vehicle's handling performance and driving comfort are greatly improved, and the technical problem of non-adjustable stiffness characteristics of the elastic components of the traditional suspension is solved. However, with the increase in the requirements for vehicle capacity and the requirements for vehicle stability, safety, and comfort, especially for storage and transportation equipment with large load changes, how to ensure that the vehicle attitude adjustment speed is consistent when the vehicle is empty or fully loaded? When the body height is adjusted, especially when it is fully loaded, the top-loaded goods are stable, how to achieve high...
