Abstract
In an actuator structure of a vehicle suspension apparatus, an operation rod of an actuator is swingably connected to a vehicle body side end of a lower suspension arm through a rubber bushing, the operation rod is contained in a body and is slidable in a longitudinal direction of the lower suspension arm, and the body is mounted on a vehicle body through a rubber mount, thereby improving durability, environmental resistance, and mounting workability of the actuator structure.
Claims15
An alignment control actuator mounted on a suspension apparatus of a vehicle for controlling alignment of the suspension apparatus comprising:
- an operation rod having at an end thereof a connection unit for swingably connecting a vehicle body side end of a suspension arm;
- an actuator body slidably receiving said operation rod for selectively sliding said connection unit along a longitudinal direction of said operation rod;
- and
- a first elastic member mounted on an outer periphery of said actuator body at a position corresponding to a neutral position of said connection unit for connecting a vehicle body member and said actuator body.
An alignment control actuator mounted on a suspension apparatus of a vehicle for controlling alignment of the suspension apparatus comprising:
- an operation rod having at one end thereof a connection unit for pivotably connecting a vehicle body side end of a suspension arm and a piston unit at the other end thereof;
- an actuator body having a cylinder unit divided by said piston unit into two hydraulic chambers, and a hollow-structured arm support unit disposed at a suspension arm side of said cylinder unit for supporting said connection unit on an inner peripheral surface, and for selectively sliding said connection unit along a longitudinal direction of said operation rod;
- and
- a first elastic member mounted on an outer periphery of said actuator body at a position corresponding to a neutral position of said connection unit;
- wherein said actuator body is connected to a vehicle body member through said first elastic member.
An alignment control actuator of a suspension apparatus having a suspension lower arm connected at an end thereof to a knuckle, said knuckle rotatably supporting a vehicle wheel, through a ball joint for receiving a longitudinal force of a vehicle body input to the vehicle wheel, comprising:
- an operation rod having a connection unit for connecting the other end of said suspension lower arm allowing pivotal movement of said suspension arm in relation to said operation rod;
- an actuator body receiving said operation rod for selectively sliding said connection unit in a longitudinal direction of said operation rod;
- and
- a first elastic member mounted on an outer periphery of said actuator body at a position corresponding to a neutral position of said connection unit for connecting a vehicle body member and said actuator body.
An alignment control method for a suspension apparatus having a suspension arm connected at one end thereof to a knuckle, said knuckle rotatably supporting a vehicle wheel, through a ball joint for receiving a longitudinal force of a vehicle body input to the vehicle wheel comprising the steps of:
- connecting a connection unit formed at one end of an operation rod to the other end of said suspension arm;
- slidably receiving said operation rod in an actuator body;
- and
- mounting said actuator body to the vehicle body through an elastic member mounted on an outer periphery of said actuator body at a position corresponding to a neutral position of said connection unit.
