Abstract
Abstract An automotive energy absorption, storage and retrieval system consisting primarily of an elastomeric member or the like for absorbing and storing the energy of a moving vehicle when the vehicle is being decelerated, by stretching the elastomeric member, and for transmitting this stored energy, of the stretched elastomeric member, to enable the vehicle to be accelerated.

An automotive energy absorption, storage and retrieval system for a vehicle having a chassis comprising: a bevel gear mounted on the propeller shaft, a second bevel gear mounted on a shaft extending at an angle to the propeller shaft and engaging said first mentioned bevel gear, a first pair of shafts extending parallel to the second mentioned shaft, a gear on each of the first pair of shafts, a pinion on the second mentioned shaft engaged with the gears on the shafts of the first pair of shafts; a second pair of shafts having each shaft in alignment with a respective one of the shafts of the first pair of shafts, a pair of selectively operable clutches, each clutch alternately connecting one of said second pair of shafts to the aligned shaft of the first pair of shafts, a gear on each shaft of the second pair of shafts, the gears on the second pair of shafts being engaged with each other, a cable spool connected to one shaft of the second pair of shafts, an elastomeric member of natural and/or synthetic rubber or the like connected at one end to the vehicle chassis, a cable connected to the other end of the elastomeric member and to the cable spool and adapted to be wound on the cable spool and a brake coupled to the cable spool, the clutches enabling energy to be transmitted from the propellor shaft to the cable spool to enable the cable to extend the elastomeric member to absorb and store energy when the vehicle is being decelerated and enabling energy to be transmitted from the elastomeric member to the propeller shaft to enable the vehicle to be accelerated, the cable spool brake acting to restrain movement of the cable spool and elastomeric member to permit the stored energy to be retained by the elastomeric member.
