Molecular spring vehicle suspension

Abstract

The invention provides a molecular spring vehicle suspension. The molecular spring vehicle suspension comprises a compressible hydraulic cylinder, pistons and molecular spring mixed media; the compressible hydraulic cylinder comprises an end cover and a cylinder body which are connected with each other, a diaphragm is arranged between the end cover and the cylinder body, and a cavity formed between the diaphragm and the cylinder body is filled with the molecular spring mixed media; the pistons comprise a guide piston and a damping piston which are connected with each other, one end of the guide piston is located in the end cover, and the other end of the guide piston extends out of the end cover; the damping piston is located in the cavity formed between the diaphragm and the cylinder body; the end, connected with the guide piston, of the damping piston is a stepped shaft with threads, the stepped shaft is used for fixing the damping piston, the guide piston and the diaphragm togetherthrough the threads, and sealing is formed; and the other end of the damping piston is a guide end, the outer edge of the guide end is in clearance cooperation with the inner wall of the cylinder body, and damping holes are formed in the guide end. The molecular spring vehicle suspension has high static and low dynamic stiffness characteristics, smoothness and maneuverability of running of a vehicle can be greatly improved, and meanwhile, installation space is saved.

Description

technical field [0001] The invention relates to a novel vehicle suspension capable of providing both elastic support and damping effect, and belongs to the technical field of vehicle engineering. Background technique [0002] As consumers have higher and higher requirements for vehicle ride comfort and controllability, it has always been the goal pursued by automotive designers to improve vehicle ride comfort and provide vehicles with excellent controllability. The core vibration damping unit of the vehicle suspension includes two parts: an elastic element and a damping element. At present, the elastic elements used in the suspension system of common vehicles on the market mainly include longitudinal leaf springs, transverse leaf springs, coil springs, torsion bars, air springs, etc. There are more or less vehicle suspensions using the above elements. Places that are satisfactory, such as vertical leaf springs and horizontal leaf springs with too high stiffness, have poor c...

Problems solved by technology

At present, the elastic elements used in the suspension system of common vehicles on the market mainly include longitudinal leaf springs, transverse leaf springs, coil springs, torsion bars, air springs, etc. There are more or less vehicle suspensions using the above elements. Places that are satisfactory, such as vertical leaf springs and horizontal leaf springs with too high stiffness, have poor comfort; in order to ensure load capacity and stability, coil springs require higher stiffness and sacrifice vibration isolation performance; the torsion bar structure is complex, Larger and has similar issues as coil springs; air springs perform better but are bulky and expensive
