Problems solved by technology

[0004] However, the existing single-swing arm suspension system and the hinge point of the frame are rigidly fixed, which can only withstand the load in the swing direction. In a complex driving environment, the comprehensive load impact is likely to cause damage to the suspension hinge point, especially It is some special vehicles in the field, and this kind of suspension system is often damaged

Abstract

The invention discloses a double-cavity floating cylinder, a single-swing-arm suspension system applying the same, and a suspension adjustment method. The double-cavity floating cylinder is used for asuspension system of a vehicle, comprises a vertically-arranged cylinder barrel and further comprises two sets of fixed pistons and fixed guiding cylinders which are integrally connected. Cylindricalstructures at the two ends of the cylinder barrel are assembled in annular grooves of the two sets of fixed pistons and fixed guiding cylinders correspondingly; the inner wall of the cylinder barreland the fixed pistons are slidably assembled in a sealed mode, and the outer wall of the cylinder barrel and the inner walls of the fixed guiding cylinders are slidably assembled in a sealed mode; anda cavity between each fixed piston and the cylinder barrel as well as an annular cavity between the fixed piston and the corresponding fixed guiding cylinder form two pressure cavities in the two sides of the pistons. In the single-swing-arm suspension system applying the double-cavity floating cylinder, the fixed pistons and the fixed guiding cylinders are fixedly connected with a vehicle frame,and the cylinder barrel is connected with a swing cylinder and connected with a wheel assembly through a rotating shaft and a swing arm. The double-cavity floating cylinder is applied to the single-swing-arm suspension system, and the single-swing-arm suspension system has the advantages that large-angle adjustment of swing arm suspension is achieved, and the suspension height and the vehicle axle base are changed on a large scale.

Description

technical field [0001] The invention belongs to vehicle suspension technology, and in particular relates to a double-cavity floating cylinder and a single-swing arm suspension system and a suspension adjustment method thereof. Background technique [0002] Suspension system is the general term for all force-transmitting connection devices between the frame of a driving vehicle and the axle or wheels, which transmits the force and moment acting between the wheel and the frame, and buffers the impact transmitted from the uneven road to the frame or body. force, attenuate vibration, and ensure the smooth running of the vehicle. The main function of the suspension system is to support the body and improve the ride. [0003] Oil-air suspension is one of the suspension forms that have developed rapidly and are widely used in recent years. With the continuous improvement of large-scale engineering vehicles, special vehicles, and off-road performance, oil-air suspension is characte...
