LiquidSpring is now available on both front and rear axles as an integrated smart suspension system on select chassis. This makes four-corner kneeling a new possibility.
An early customer taking advantage of the kneeling upgrade is ARBOC, who has added it as an upgrade available on their Spirit of Mobility model. The new upgrade option allows for the entire bus platform to be lowered for easy access with no giant step-up for riders, especially appreciated by the elderly and other passengers with accessibility issues. Rear suspension only models could also kneel, but this was not always helpful for the front-loading doors of a shuttle bus.
The LiquidSpring CLASS® suspension system was originally offered as a rear suspension only, where it is needed most. From variable loading weights to lessening jolts passed along the frame from front to back, the rear suspension is still the standard product from LiquidSpring and provides major support to the smart suspension system. All front axle suspension systems must be accompanied by a matching rear suspension system for connectivity.
Besides four-corner kneeling, the optional front suspension upgrade provides further improvement to ride and handling. It also notably provides more driver comfort by reducing felt vibration on rough roads. The front suspension, being underneath the driver, is a large contributor to the shaking sensation felt through the seat and steering wheel of the vehicle. LiquidSpring’s improved absorption of these forces reduces felt vibrations significantly, giving drivers a more luxurious and safer feel to the ride.
