ABSTRACT:
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a stabilizer for an automobile, more particularly a pneumatic type of stabilizer for an automobile, which uses the elastic force of the compressed air as an elastic means and can be used in every kind of automobile.
Generally, all kind of automobile has a suspension system in order to get a good ride quality when a passenger rides on an automobile. Then if the suspension system equips a spring having a low spring constant, when the automobile drives on the corner, the spring mounted on the suspension system of the inner side wheel in the automobile is much compressed by the centrifugal force. Therefore the automobile is much tilted and the passenger of the automobile gets a bad ride quality.
In order to solve the above problems, a stabilizer is mounted on the suspension system that returns the body of the automobile to the original position and keeps balance the body of the automobile in equilibrium, when the automobile drives on the corner. Both ends of the stabilizer are respectively connected with a left suspension arm and a right suspension arm of the suspension system, and the center portion of the stabilizer is supported on the frame of the automobile.
The stabilizer itself has a twist elasticity, which does not be applied to the suspension system when both of the left wheel and the right wheel are simultaneously moved upward or downward. But the left wheel and the right wheel are differently moved upward or downward each other, for example when the automobile turns the corner and tilted toward a side, the twist elasticity of the stabilizer is applied to the suspension system and keeps the body of the automobile in equilibrium.
Then the prior traditional stabilizer is a static type. The static type of the stabilizer has some problems.
The prior stabilizer cannot be properly operated when an impact is applied on the suspension system. And since twist elasticity cannot be adjusted according to the kind of the automobile in the static type of the stabilizer, the stabilizer is differently designed according to the kind of the automobile. Therefore many kind of stabilizer are needed to adapt every kind of automobile.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a pneumatic type of stabilizer for an automobile, which can adjust the twist elasticity and can be adopted on every kind of automobile by simply adjusting the pressure of the air in the stabilizer.
The present invention to achieve the above object comprises a cylindrical case in which a left rotating rod and a right rotating rod having blade respectively are pivotally mounted, a rotator connected with the outer end of the rotating rod and which protruded out of the cylindrical case, a connecting rod connected with the end of the rotator, and two arms connecting the connecting rod with a suspension arm of a suspension system.
The stabilizer for an automobile in accordance with the present invention uses the pressurized air as elastic means to return the body of the automobile, when the automobile drives on the corner and tilted toward a side.
Furthermore the stabilizer can be adopted in every kind of automobile by controlling the elasticity of the pressurized air. And the elasticity of the air can be adjusted by controlling the amount of air injected into the cylindrical case
When the automobile drives on the corner and tilted toward a side, the blades compresses the air in the cylindrical case between the both blades. Then the compressed air reacts the blades to return the body of the automobile to the original position.
