An impact moderating mechanism comprising:
- a pair of identical shock absorbing and transferring devices equipped one on each end of a chassis of an automobile respectively;
- each said shock absorbing and transferring device comprising an outer bumper positioned parallel and in front of an original bumper of the automobile, a pair of first hydraulic cylinders perpendicularly and respectively secured with their fore ends adjacent to an inner surface of the lateral ends of said original bumper, each of first hydraulic cylinders having a cock stem passing through a first passage in said original bumper and a first valve port, said cock stem having a first end perpendicularly connected to an inner surface of said outer bumper and a second end perpendicularly connected to a first valve gate inside said first hydraulic cylinder and biased by a pair of first coil springs therein, a pair of first conduits connected crosswise to the inner peripheries of said first hydraulic cylinders;
- a pair of second hydraulic cylinders spacedly and respectively secured on their upper peripheries to the bottom of the floor panel of said automobile, each of said second hydraulic cylinders having a second cock stem passing through a second passage on said original bumper which has a first end connected to one of a pair of leaf springs on said outer bumper and a second end connected to a second valve gate through a second valve port and biased by a pair of second coil springs;
- said pair of leaf springs juxtaposed and connected to the inner surface of said outer bumper, each having a plurality of arcuate plates in progressive lengths and centrally packed by a packing member which has a tubular connecter with a portion facing inwards for coupling with said second cock stem;
- a pair of second conduits for respectively connecting the rear ends of said pair of second hydraulic cylinders on one end of said chassis to the rear ends of said pair of hydraulic cylinders on the other end of said chassis;
- and
- a pair of supplementary conduits respectively connecting the outer peripheries of said pair of second hydraulic cylinders between two ends of said chassis thereof;
- whereby said pair of first hydraulic cylinders and said pair of leaf springs can absorb a small portion of a bump wave on their own end when said outer bumper is subjected to an external impact and transfer a larger portion of the bump wave to the other end of said chassis.
