A self-leveling shock absorber is a device that automatically adjusts the height of a vehicle. As a result, driving becomes a whole lot more efficient for the driver.. It works by measuring the distance between the vehicle and the ground and then automatically adjusting the height of the suspension.
What is a self leveling shock absorber?
Nivomats are self leveling monotube shock absorbers, which utilize movement of the vehicle between the chassis and the body to create mechanical energy. It has a pump mechanism and oil reservoir that increases the pressure to its accumulator therefore lifting or leveling the vehicle.
How does a shock absorber work?
The way they work is as the load increases (such as with cargo and passengers) the pressure increases in the shock displacing fluid from its internal reservoir to its valving system increasing the spring rate essentially preventing the vehicle from “squatting".
How does a self leveling rear suspension work?
Land Rover developed a self-levelling rear suspension using the "Boge Hydromat" self-energising hydraulic strut. Of similar construction to a hydraulic shock absorber the strut used the motion of the suspension travelling over bumps to pump itself back up to a pre-set height.
What is self levelling?
Self-levelling refers to an automobile suspension system that maintains a constant ride height of the vehicle above the road, regardless of load. Purpose. Many vehicle systems on a conventional vehicle are negatively affected by the change in attitude coming from changes in load - specifically a heavy load in the rear seat or luggage compartment.
How does load leveling suspension work?
The load leveling shocks use the motion of the suspension to pump them up, so when you first hook up your trailer the rear may sag a little, but after driving a short distance the suspension motion should pump the shocks up to return the rear ride height back up to normal.
Can I replace self-leveling shocks with regular shocks?
Inasmuch as the spring and the shock were matched for handling and performance you should NOT attempt to substitute a regular shock in a vehicle equipped with load leveling.
What cars use Nivomat shocks?
Nivomat shocks are used by Chrysler, Ford, General Motors, Jaguar, Kia, Mitsubishi, Saab, Volvo and other OEMs. The system is also available on the GM Suburban and Tahoe as part of ZW7 Premium Smooth Ride Suspension.
How do I know if I have self-leveling shocks?
You can look under the car from the rear, if you see large plastic ribbed plastic on the shocks, you likely have Nivomat's. You can also measure the car before you drive, drive at least a mile and measure again. If you raise at least 1 inch, you likely have them.
Can you put regular shocks on a air ride suspension?
So Yes, you can put regular struts on an air ride yukon. But note; It's not all that easy to replace the air ride suspension with regular shocks.
Which of the following shock absorbers is also called self-leveling?
Pressure placed on something. Typically, an air shock absorber used in an automatic load-sensing system that adjusts ride height (ground clearance) automatically, such as when additional weight is added to the vehicle; also called self-leveling.
Can I replace Nivomat shocks with regular shocks?
Even though the conventional shocks may fit, It is not recommended that you replace your Nivomats with traditional shock absorbers. If the vehicle was originally equipped with Nivomats then it is recommended that they are to be replaced with Nivomats only.
How do I know if I have Nivomat suspension?
If you are wondering if you have Nivomats, check your manual, or try to get a look at them. They will only be in the rear. Nivomats have a thinner end toward the eyelet (although Monroe Nivomats and some others have a built-in accordion boot cover).
Can Nivomat shocks be rebuilt?
Yes, you can! If your car came with a Nivomat suspension, installing a different kind of suspension is not only possible, it's very simple.
What are load leveling shocks?
Load-leveling rear shock absorbers or struts are used with an electronic height control system. Load-leveling shock absorbers use air pressure supplied to the shock absorbers to maintain rear suspension height. Load-leveling shock absorbers may be called air shocks.
What is GM premium ride suspension?
Premium Smooth Ride: indicated by the RPO code ZW7. This suspension uses a conventional suspension in the front, but the rear uses a self-contained, self-leveling Nivomat shock in the rear.
How does Mercedes self-leveling suspension work?
The Self-Leveling-System (SLS) adjusts the ride height of the rear end when it is loaded to keep the rear end at the proper riding level. The springs and the SLS maintain the unloaded height. The SLS maintains height when loaded by pressurizing the system which lifts the rear.
When did Rolls Royce remove the rear levelling?
In 1966, Rolls-Royce licensed Citroën's hydropneumatic system to fit to the rear axle of the Silver Shadow. At first, both the front and rear of the car were controlled by the levelling system; the front levelling was removed in 1969 as it had been determined that the rear levelling did almost all the work.
Why are front brakes easier to lock up?
When braking quickly in this situation, the front brakes will be easier to lock up because of the lack of weight transfer to the front of the vehicle.
When did the rear suspension start?
In France in 1954, Citroën introduced the first self-levelling rear suspension on a production car, and then in 1955 pioneered self-levelling of all four wheels, using its hydropneumatic system. These cars maintain an exact height over the road when the engine is on - height control valves attached to the roll bars via linkages would open to add or drain fluid from the suspension, and when the desired height was reached the valve would automatically close due to its design. Later models would use electronic height sensors and motors so adjustment could be achieved with the engine off.
