Abstract:
An automotive suspension system which is rotatably connected between one portion of a wheel axle and two portions of an automotive frame, comprising;a first hydraulic cylinder having a small inner diameter and integrated with a strut-type shock absorber, said absorber made by shortening the length of an existing strut type shock absorber and reinforcing the compression force with a spring, a bottom end portion of said first hydraulic cylinder being combined with a top end portion of a second hydraulic cylinder having a larger inner diameter than said first hydraulic cylinder, and a bottom end portion of a rigid suspension rod, respectively, at appropriate combining angles, in such a manner that the combined portions thereof are rotatably connected to each other;said second hydraulic cylinder having a bottom end portion connected with the wheel axle, and said suspension rod having a top end portion connected with said automotive frame, and said strut type shock absorber having a top end portion connected with said automotive frame, said top end portion of said suspension rod installed to be disposed higher than the horizontal position of a center of junction of the combined portions and attached toward an inward direction of said automotive frame;said strut type shock absorber being attached between first and second spring fixing boards to allow a first coil spring to be inserted thereinto and separated therefrom, and said first hydraulic cylinder being adapted to be attached between said second spring fixing board and a third spring fixing board to allow a second coil spring having a relative smaller compression force than said first coil spring to be inserted thereinto and separated therefrom; anda flexible hydraulic hose for connecting said first and second hydraulic cylinders to move oil pressure toward each other and having first and second oil inlet holes respectively formed on the external surfaces of said first and second hydraulic cylinders, each oil inlet hole having a locking device thereon.
