Suspension Strut / Shock Absorber: Description and Operation
Shock Absorber
REAR LOAD LEVELING
A new type of load-leveling shock is available.
Description
The self leveling shock absorbers are a self-contained vehicle leveling system and shock absorber combined.
Requirements
It does not require an external compressor, hoses, height leveling sensors, etc. It uses road inputs (bumps, stops, starts, turns, acceleration,
deceleration, etc.) to activate pumping, which is just the extension and compression of the shock absorber.
Design
On the outside, it looks like a larger than normal shock absorber. Internally, it consists of a hydraulic pump and gas-spring cushion for leveling, as
well as the normal shock absorbing mechanism. All the height leveling sensors, pump, etc., are contained inside the shocks.
Mounting
The shocks are mounted at an angle, parallel to the springs and forward at the top. This design provides greater stability in addition to controlling
ride motion. These new load-leveling shock absorbers use longer fasteners than the standard shock absorbers, although the fasteners are longer, the
torque specifications are the same.
