Damping shock absorber for hydraulic interconnection suspension

Abstract

The invention discloses a damping shock absorber for a hydraulic interconnection suspension. The damping shock absorber comprises a liquid storage cylinder, wherein a piston cylinder is arranged in the liquid storage cylinder, a top valve assembly is arranged at the top end of the piston cylinder, a bottom valve assembly is arranged at the bottom end of the piston cylinder, and a cavity in the damping shock absorber is divided into a liquid supplement cavity between an upper end cover and the top valve assembly, an upper cavity between the top valve assembly and a piston, a lower cavity between the piston and the bottom valve assembly, and a liquid storage cavity between the piston cylinder communicating with the lower part of the bottom valve assembly and the liquid storage cylinder through the top valve assembly, the piston, the bottom valve assembly and the piston cylinder; an upper thread hole connecting with an oil tube is arranged in the upper end cover; the upper thread hole communicates with the liquid supplement cavity; a lower thread hole connecting with the oil tube is arranged in the liquid storage cylinder; the lower thread hole communicates with the liquid storage cavity; a throttle hole is arranged in the top valve assembly and the bottom valve assembly respectively; and the liquid storage cavity is charged with a compressed gas with a predetermined pressure to play a role of an energy accumulator. The damping shock absorber disclosed by the invention integrates the functions of a double-acting hydraulic cylinder, a throttle valve and the energy accumulator, and is compact in structure and convenient to directly apply to the traditional suspension structure.

Description

technical field [0001] The invention belongs to the technical field of damping shock absorbers, in particular to a damping shock absorber for a hydraulically interconnected suspension. Background technique [0002] The hydraulic interconnected suspension system replaces the traditional suspension system, which can improve the maneuverability of the vehicle without reducing the ride comfort of the vehicle. Especially on heavy-duty commercial vehicles, the appropriate hydraulic interconnection suspension system structure has good anti-roll and anti-pitch performance, thereby enhancing driving safety and reducing accidents. [0003] The current hydraulic interconnected suspension system consists of a hydraulic cylinder installed between the axle and the vehicle body, a throttle valve, oil pipes connected to the hydraulic cylinder, and an accumulator. The system structure is complex and requires redesign of the entire vehicle suspension system, and occupies A large amount of sp...
