Parker Smart Suspension System

The Parker Smart Suspension provides greater vehicle reliability with reduced air consumption, including greater functionality. Ideally suited for bus and coach applications, this electronically controlled air suspension system is designed to adjust air spring height and pressure to manage overall vehicle height. The system works in conjunction with the bus suspension air springs, air spring height sensors, and wheelchair ramp sensor to provide the following functions:

 

          Improve Ride Control | Kneeling | Over-raise | Low-ride | Fault Tolerance| Height Management

Capabilities

As the bus maneuvers through corners, the system will minimize roll movement, potentially eliminating the need for a sway bar.
Improve Ride Control
Upon reaching a stop, the bus driver can lower the bus to the curb, making entry and exit through the door easier.
Kneeling
Raise ride height at all air spring positions (adjustable per customer spec) to allow for increased approach, break-over and departure angles for road conditions.
Over-Raise
Lower the ride height position based on vehicle speed.
Low-Ride
In the event a system issue is detected, the Parker system will minimize the impact to the vehicle by degrading suspension functionality, until a point where vehicle service can be provided.
Fault Tolerance
Two additional height settings are also available based on end-customer needs.
Height Management
