Abstract

The invention provides a solenoid valve assembly externally arranged on an absorber and the absorber. The solenoid valve assembly externally arranged on the absorber comprises a solenoid valve part and an overflow valve. The solenoid valve part comprises a solenoid valve deck, a solenoid valve body, a coil, a solenoid valve element, an armature, a first spring and a second spring. The overflow valve comprises an overflow valve deck provided with open holes formed in the two ends in the axial direction, an overflow valve body provided with an oil inflow hole and an overflow hole, an overflow valve seat provided with a center hole, an overflow adjusting assembly, an overflow valve element, a pressure adjusting spring and a supporting piece. Through the overflow valve of the solenoid valve assembly externally arranged on the absorber, damping adjustment can be achieved through the overflow adjusting assembly of the overflow valve when the oil pressure is small and a throttling hole is closed, so that the solenoid valve assembly externally arranged on the absorber is high in damping adjustment response speed, stable in performance and capable of meeting the requirements that damping force is adjusted continuously in real time in the suspension frame movement process.

Description

technical field [0001] The invention belongs to the technical field of vehicle vibration reduction, in particular to a shock absorber external electromagnetic valve assembly and a shock absorber. Background technique [0002] Variable damping shock absorber is an important part of active and semi-active suspension systems, and its performance directly affects the handling stability and ride comfort of the vehicle. At present, variable damping shock absorbers are generally divided into stepping motor control orifice type, magneto-rheological type, electro-rheological type, and solenoid valve type. Among them, the stepper motor controls the orifice shock absorber to respond slowly, which cannot meet the requirements of real-time adjustment of the damping force during the suspension movement process; the magneto-rheological shock absorber and the electro-rheological shock absorber are still in the stage of theoretical research, and the structure is complex and The performance ...
