Embodiment Construction
[0043] figure 1 is a schematic structural diagram of an electronically controlled shock absorber assembly according to a specific embodiment of the present invention.
[0044] This embodiment provides an electronically controlled shock absorber assembly 100, the electronically controlled shock absorber assembly 100 may include an electronically controlled shock absorber 10, and the electronically controlled shock absorber may include an oil secondary circuit 12 and an oil main circuit 11. A solenoid valve 20 may also be provided on the auxiliary oil circuit 12 , and the solenoid valve 20 is connected with a control device 30 .
[0045] Specifically, the magnitude of the opening of the solenoid valve 20 is directly proportional or inversely proportional to the magnitude of the current. The larger the current, the larger or smaller the opening of the solenoid valve 20 is. Taking the opening of the solenoid valve 20 as an example in direct proportion to the current, the larger...

The invention provides a service life monitoring method of an electric control shock absorber assembly and the electric control shock absorber assembly, and relates to the technical field of shock absorbers. The invention provides a service life monitoring method of an electric control shock absorber assembly, the electric control shock absorber assembly comprises an oil auxiliary loop and an electromagnetic valve arranged at the oil auxiliary loop, and the service life monitoring method comprises the following steps: obtaining a current current value of the electromagnetic valve and a continuous first time value under the current value; according to the current current value and the corresponding time value, the first life percentage consumed by the electric control shock absorber is obtained. According to the life detection method of the scheme, the consumed life percentage of the electric control shock absorber can be directly obtained according to the current value and the corresponding time value, so that when the electric control shock absorber consumes all the life can be known, and replacement can be prompted in time when the shock absorber needs to be replaced; and the consequences of damping reduction of the electric control shock absorber, intensified vibration of the vehicle body and the like are avoided, so that the driving experience is prevented from being influenced.
Description
technical field [0001] The invention relates to the technical field of shock absorbers, in particular to a life monitoring method of an electronically controlled shock absorber assembly and the electronically controlled shock absorber assembly. Background technique [0002] The invention relates to a vehicle suspension system equipped with electronically controlled shock absorbers. At present, the shock absorbers used in the suspension of most automobiles are mechanical hydraulic shock absorbers. The basic principle is that the oil reciprocates through some fixed small holes to generate friction, and a part of the vibration energy of the suspension passes through the friction when the suspension is moving. The force is converted into heat and dissipated, dissipating vibration energy, thereby reducing the vibration amplitude of the suspension. Some high-end models will be equipped with electronically controlled shock absorbers. The principle is to add a solenoid valve to the...
