Single-barrel type ring-shaped cavity high-pressure hydro-pneumatic spring

Abstract

The invention discloses a single-barrel type ring-shaped cavity high-pressure hydro-pneumatic spring. The single-barrel type ring-shaped cavity high-pressure hydro-pneumatic spring comprises a cylinder barrel (1), a piston rod (2), an upper hinge (3), a damping valve (4), a hydraulic upper limiter (5), a floating piston (6), a hydraulic lower limiter (7), a locking nut (8), a lower end cover (9),a guide sleeve (10), a lubricating sleeve (11), a lower hinge (12) and a pressure cover (18), wherein a gas chamber (13) is arranged inside the piston rod (2), and is separated from an oil chamber (14) through the floating piston (6); the damping valve (4) is in fastening connection to the piston rod (2) through threads; an oil passing hole of the damping valve (4) is used for enabling the oil chamber (14) to communicate with a hydro-pneumatic spring ring-shaped cavity (47), and high-pressure oil is in the ring-shaped cavity (47); the upper hinge (3) is connected to the upper end of the cylinder barrel (1); and the hydraulic lower limiter (7), the guide sleeve (10) and the lubricating sleeve (11) are sequentially mounted at the lower end of the cylinder barrel (1), and the hydraulic lowerlimiter (7) is positioned at the innermost side.

Description

technical field [0001] The invention relates to a high-pressure oil-gas spring with a single-tube annular cavity, which belongs to the category of hydraulic machinery. Background technique [0002] Future wars put forward high requirements for tanks and armored vehicles, and their mobility is directly related to the firepower, maneuverability and battlefield survivability of tanks and armored vehicles. Although the high mobility of tanks and armored vehicles is powered by the power and transmission system, it is ultimately realized by the action system, and the suspension system is the key to the entire action system. Therefore, the performance of the suspension system will seriously affect the mobility of the vehicle. Level. At this stage, the suspension devices equipped on tanks and armored vehicles in our country are relatively single in form and have limited performance. Therefore, research on new suspension devices is of great significance for achieving high mobility o...

Problems solved by technology

Therefore, torsion bar springs have been widely used in various tanks and tracked armored vehicles since the end of World War II, such as the M1 series of the United States, the Leopard 2 series of Germany, the T-72 of Russia, and the 99 series of main battle tanks of our country; The rod spring also has certain shortcomings, that is, the suspension stiffness is basically unchanged. When driving on a road with better road conditions, the stiffness appears to be larger, which will increase the vibration frequency of the vehicle, and the occupants feel bumpy and poor in ride comfort; When driving on uneven roads, the stiffness appears to be small, and the vibration amplitude of the vehicle is large, which reduces the average off-road speed
