  • HWH Active Air, is a four-point electronically controlled suspension system that provides ride comfort while driving by rapidly adjusting the suspension system toward proper height. See US Patent # 6,665,597 B1 Click for next slide
  • Slide 3
  • Windy conditions, curvy roads and aggressive lane changes can cause an RV to lean. HWH Active Air senses such movements and adjusts the individual suspension air bags creating the proper ride height. With Active Air Without Active Air Click for next slide

  • Curve Anticipation Drivers anticipate turns by turning the steering wheel just before reaching the turn. With a sensor on the steering shaft, these reactions can be measured. This data is sent into the CPU to bring the height control up to full speed. When the vehicle enters the turn a height control sensor activates a high flow air valve. This rush of air into the bag minimizes the sway of the vehicle. See US Patent #6,665,597 B1 Click for next slide
  • Slide 5
  • The Steering Sensor (located on steering shaft) detects steering wheel rotation to anticipate the drivers intentions, thus alerting the automatic system that air bag adjustment may be necessary. Click for next slide

  • HWH Advanced Design Height Control Sensors Each controller runs four channels of data: High setting for getting out of rough terrain (campgrounds etc.) Medium setting for normal use. Low setting for low grade doors, tree limbs etc. Encoder senses the position of axle relative to the frame continually. HWH Control Sensors are ruggedly built to withstand the effect of running on roads with ice, snow, rocks, etc. No need to carry a spare! Click for next slide
  • Slide 7
  • Data from the position sensors is multiplexed to the HWH Active Air central control unit. Front and rear air manifolds respond rapidly to the central control unit to inflate or deflate the air suspension to keep the motorhome at a constant height.

  • Four Point Stability: It is critical while traveling down the road that the front air bags need to operate at the same pressure (example, in a sudden stop situation equal air pressure keeps the same braking force on both wheels). If the coach is heavier on one side, it does not overload the front tire rather spreads load over three tires (if tag axle), reducing front tire blow outs. Click for next slide
  • Slide 9
  • Wheel Height Averaging Bar: Keeps the front of the vehicle at the proper ride height while counteracting the roll forces by adding air to the outside bag and removes air from the inside bag. This keeps the proper front height in long curves with rough roads. Unlike using stiff shock absorbers tires have more freedom to track the road adding to driver comfort. The arrangement provides the stability of a four point suspension without the inerrant problems caused by a four point suspension. See US Patent #7,806,417 Click for next slide

  • HWH Systems Control Module provides self-monitoring and control of the HWH Active Air Suspension system. The Systems Control Module also offers features such as: Full diagnostics onboard/Self-diagnostic capability Aids in trouble shooting systems. Compatibility of RV Components for seamless communication. The Systems Control Module not only controls the suspension system it also controls slide-outs ~ leveling systems ~ awnings ~ generators ~ automatic steps ~ and much more. Click for next slide

  • HWH Automatic Air Leveling Included! HWH Active Air Suspension Systems include our BI-AXIS Automatic Air Leveling package. This allows you to level your coach, with the touch of a button, when you are parked. Fuel economy mode! Saves fuel while on straight-aways by reducing the response, resulting in less air consumption. Manual over-ride! Can be used when traveling below approximately 10 mph to raise the vehicle to clear obstacles such as steep driveways or lower vehicle to enter garages. Driver selectable! High, medium and low heights for front, right side or left side allow increased comfort on roads with high crowns, rough surfaces and windy conditions. Self-monitoring system! Notifies the driver of conditions that need addressing. Click for next slide

  • Redundancy in systems! In case of repairs the RV can be driven safely to a service center without the expense of towing fees. Tech Service! Tech service is available at HWH 1-800-321-3494 Click for next slide
