OF DE. Effective date : Year of fee payment : 4. Year of fee payment : 8. Year of fee payment : A control system for a lift axle suspension wherein two or more axle suspensions are mounted on a vehicle frame and a liftable axle is automatically raised or lowered depending on the load on another of the axle or axles. An override to the automatic lift system is provided when the vehicle is fully loaded to lift a liftable axle selectively for a limited, relatively short period of time to assist in maneuvering the vehicle. The control system detects the load on one axle and automatically raises the second axle to the raised position when the load on the first axle is below a first predetermined value and automatically lowers the second axle to the lower position when the lower load on the first axle is above a predetermined value which is greater than the first predetermined value. A delay is provided in the operation of the control system to lower the second axle upon the detection of the load on the first axle to compensate for road bumps. An electrical sensor coupled to the load detector provides a signal to an electrical circuit in the controller to control the operation of the second axle. In one of its aspects, the invention relates to a lift axle control system having a means for automatically raising and lowering a lift axle depending on the load in the full time down axle s.

Exhaust Brake and Exhaust Pressure Modulator. The foregoing has been a description of a conventional tandem axle suspension with a liftable axle.

Need Help? The axle is rated based on the lowest capacity component fitted to that axle. The installer should check that the tire and rim combination meets the load requirements. The rating information on the Hendrickson vendor provided hubs can be found at:. For KIC wheel ends standard fit : www. A non-steerable lift axle that is not raised when turning, especially in a tight corner, will scrub concrete and impose high lateral stress on the wheels and chassis components of your vehicle. Raising the fixed axle when cornering will help decrease tire wear, reduce maintenance costs, and ensure proper functionality of the auxiliary lift axle when in use. It is also important to be aware of the regulations within the states that your vehicle will operate in.

The mesh filter helps to prevent debris from entering the system. Section 12 Diagnostic Tool Software. Relay Valve. Roll Stability Systems. For setting instruction of the lifting axle control valve please check the pages of the document "Pneumatic brake equipment for trailer vehicles" Vehicle application India : Volvo. The outlet pipe 62 from the solenoid control valve 56 is connected to the control inlet of control valve 60 through pipe 62, T- connector 64 and pipe Briefly, the control system has generally included a manual switch in the vehicle cab to control valves in the air supply system to the air springs 44 and 36 for control of the lifting. In this case the input to the controller from the sensor comprises a voltage which is generated from the transducer circuit Hydraulic Load Sensing Valve. The foregoing is a description of a conventional pneumatic and electrical control system for a tandem-axle suspension system with a liftable axle.

Need Help? The complete 20, pound capacity suspension system and kit are currently available for truck mount configuration only. A kit version is also available for 13, pound capacity in truck or trailer mount configurations.

Further, a single pressure sensor will allow the control of the lift axle by measuring the load on the down axle only. Air suspension deflation control system with automatic reinflation and control reset. Exhaust all pressure in lift axle air springs and vehicle air system. Hedlund et al sense the load on an axle bearing leaf spring through a lever arm, one end of which is connected to an end of the leaf spring and the other end of which is connected to the idle-wheel axle. A delay is provided in the operation of the control system to lower the second axle upon the detection of the load on the first axle to compensate for road bumps. And best of all they are assembled in USA. USA en. The control system uses solid-state electronics and is far less costly than pneumatic systems which have been used in the past. Because the voltage input to the integrated circuit had previously been at zero, the integrated circuit will pass the current through the diode D1, the resistor R2 and through the transister Q1 to the solenoid control valve Compressor - Stand Alone.
