BASIC CAR SUSPENSION SYSTEM

As a vehicle travels over a rough surface, it undergoes vertical acceleration. This can be unpleasant for passengers and can degrade the vehicle over time.

In modern vehicles, a set of springs and shock absorbers known as a suspension system serves to minimize these unwanted effects.

The spring absorbs kinetic energy involved in vertical motion of the tyre while the shock absorber acts as a damper on the spring. Typical shock absorbers convert spring energy into thermal energy, releasing wasted heat into the environment.

BASIC CAR SUSPENSION SYSTEM

HYDRAULIC SHOCK ABSORBERS

Most modern vehicles make use of hydraulic shock absorbers.

In a hydraulic shock absorber, a piston slides back and forth in a cylinder filled with a viscous fluid, forcing it through a series of flow valves and tiny orifices. As the fluid passes through the small orifices it experiences viscous friction, causing the fluid to heat.

HARNESSING WASTED HEAT

Genshock technology offers a means for salvaging the wasted energy associated with hydraulic shock absorbers.

Instead of using tiny orifices to create viscous friction and damp the springs, Genshocks route fluid through hydraulic motors.

The fluid experiences resistance as it acts on the motor, thus damping the springs. Instead of creating wasted thermal energy, Genshocks create rotational kinetic energy in a motor which powers an electric generator.

WORKING OF GENSHOCK

When testing the Gen Shock, it was discovered that each shock absorber generates an average of around 1 kW while on the road. This would be enough to displace the large alternator load in heavy trucks and other large vehicles.

INSTALLATION OF GENSHOCK

GenShock is a turnkey solution that replaces normal shock absorbers.

Installation is a simple bolt-on retrofit, with the electrical leads of each shock wired into a central power regulator and into the truck's electrical bus.

Quick, easy, and inexpensive.

TESTING OF GENSHOCK BY US MILITARY

US Army's Tank Automotive Research, Development, and Engineering Center (TARDEC) recently completed a four week accelerated durability test of GenShock technology on the M1152 HMMWV.

Testing was conducted under a CRADA agreement between Levant Power and US Army. On an MTS 4-post hydraulic shaker, the 3,000 mile test rotated six Aberdeen Test Center (ATC) courses, with periodic RMS course characterizations on the GenShock-retrofit M1152A1 HMMWV Enhanced up-weighted to 11,570 lbs.

GenShock was subjected to velocities in excess of 1.5 m/s and generated peak power outputs of over 600 watts. The Levant units had a 0% failure rate over the duration of the test and post-test dynamometer characterization demonstrated less than 5% deviation from pre-test damping performance. 

M1152 HMMWV

The US Army test was coupled with an in-house 3.8 million-cycle dynamometer durability test, exceeding the specification for the original equipment shock absorber on the HMMWV (MIL-SCD 12480613). Post-test characterization demonstrated negligible changes in damping force from pre-test performance.

In addition, since GenShock recovers energy, it runs cooler than an energy-dissipative shock. Thermal tests indicate that GenShock lasts 71% longer than a passive shock absorber before reaching temperature (ambient to 100°C test).

FUTURE OF GENSHOCK

The GenShock system is making its debut in the military marketplace.

If all goes well it will soon progress to production in civilian vehicles, and would likely become available to consumers as an aftermarket addition to their vehicles as well.

Some trucking companies have already installed the system for testing purposes and, according to preliminary results, they already anticipate an astounding 90 percent return on their initial investment.
