Abstract
An electronic control suspension (ECS) system for vehicles is provided. The ECS system includes a strut assembly which is coupled to a vehicle body, and a lower portion of which is inserted through the housing so as to absorb the rocking from the wheel. A vehicle-height control module converts a rotating force of a motor to a linear motion of the strut assembly when the rotating force of the motor is provided to a screw section thereof surrounding the stmt assembly. This allows the strut assembly to be vertically moved relative to the housing, thereby controlling the height of a vehicle.
Claims6
An electronic control suspension (ECS) system for vehicles, comprising:
- a housing having an open upper end and a lower end coupled to a wheel;
- a strut assembly coupled to a vehicle body at an upper end of the strut assembly and a lower portion of which is inserted through the upper end of the housing to absorb rocking transmitted from the wheel;
- a lifting shaft fitted around a portion of the strut assembly;
- an elastic member provided between an end of the inside of the housing and a lower end of the lifting shaft to provide elastic force to the lifting shaft, wherein the elastic member exerts a force to push the lifting shaft upwards by a rotating force provided by a motor;
- and
- a vehicle-height control module that converts the rotating force of the motor to a linear motion of the strut assembly when the rotating force of the motor is provided to a screw section thereof surrounding a portion of the strut assembly to allow the strut assembly to be vertically moved relative to the housing to control the height of a vehicle.
