BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a buffer apparatus for an automobile, and more particularly to a buffer apparatus for an automobile which is simple in structure and mounted on a torsion axle to prevent a rolling of an automobile.
2. Description of the Prior Art
Referring to FIG. 1, there is shown a general buffer apparatus for an automobile. As showing in the drawing, the buffer apparatus ha a coil spring mounted between a chassis and a torsion axle. In the buffer apparatus shown in the drawing, a shock applied to a wheel of an automobile is transmitted to the chassis through the coil spring. Since the shock is however absorbed at the chassis, shock absorbing capability is low and also rolling of an automobile body is still generated, thereby providing poor riding feeling.
A buffer apparatus for an automobile for overcoming the above-mentioned problems is disclosed in Korean Utility Model Publication No. 9688/1990. FIG. 2 shows the buffer apparatus disclosed in the publication. As shown in the drawing, the buffer apparatus comprises a first coil spring mounted on a torsion axle and protruded upward which is adapted to absorb a vertical shock and to transmit the shock to the chassis, a crank plate placed between a chassis and the torsion axle and secured at its free end to an upper end of the first coil spring, and a second coil spring mounted between the chassis and the crank plate which is adapted to absorb a horizontal shock and to transmit the shock to the chassis. In the buffer, a shock applied to the torsion axle is firstly absorbed by the first coil spring in its vertical component and further absorbed by the second coil spring in its horizontal component. That is, the buffer is designed to transmit a vertical shock applied thereto to a side wall of the chassis in order to cause riding feeling to be enhanced.
However, since the first and second coil springs are positioned at a right angle with reference to each other, breakages of the coil springs and the crank plate are frequently occurred. In order to prevent the breakages, coil springs and crank plate having high strength must be used, thereby causing the manufacturing cost to be heightened.
SUMMARY OF THE INVENTION
The present invention has been made in view of the above-described problems occurring in the prior art and an object of the invention is to provide a buffer apparatus for an automobile which comprises a simple spring mounted a torsion axle and which is adapted to cause a wheel of the automobile to be in contact with the ground always and to prevent rolling phenomenon of the automobile.
Another object of the present invention is to provide a buffer which is adapted to transmit back a shock applied to a wheel and a load by weight of an automobile not to a chassis but to a torsion axle to improve riding feeling.
In accordance with an embodiment of the present invention, the objects mentioned above can be accomplished by providing a buffer apparatus for an automobile comprising: an U-shaped bar pivotally connected to a chassis at its both ends and having a rotatable roller inserted in a middle portion thereof; a spring having a lower elastic bar extended from a hinge portion and fixed to a chassis and an upper elastic bar extended from the hinge portion and positioned between the chassis and a torsion axle, the upper end of the upper elastic bar being disposed in the U-shaped bar and in contact with the roller by elasticity of the spring; a hinge pin fixed to the chassis and connected to the hinge portion of the spring; and a connecting rod pivotally connected between a middle portion of the U-shaped bar and a torsion axle; whereby the upper elastic bar restricts an upward movement of the roller and the lower elastic bar supports the chassis so as not to allow vibration of the torsion axle to be transmitted to the chassis.
In accordance with another embodiment of the invention, the connecting rod may be a shock absorber.
In accordance with still another embodiment of the invention,
