Hydraulic over Air Relay Valve

MICO® Hydraulic over Air Relay Valves output air pressure in proportion to the hydraulic input pressure. Hydraulic input pressure, from a component such as a master cylinder or hydraulic control valve, sends a pilot signal to the relay valve to modulate air brake pressure. An example application might be controlling an air braked trailer from a hydraulically braked towing vehicle that has an air power source. MICO has three hydraulic over air relay valve designs: Single input provides one hydraulic pilot port to control modulated air braking pressure. Dual input provides two independent pilot ports to control modulated air braking pressure. The dual design function is the same as a single design when pilot pressure is applied to either the P1 or P2 port. When pilot pressure is applied to both P1 and P2 ports, at the same time, controlled air braking pressure ratio increase proportionally. The P1 and P2 ports of the dual input relay valve can be of different pressure ratios. Steering assist applications may use a dual input design relay valve. Tandem input functions the same as the signle design except it provides redundancy by having two independent pilot pressure ports. H6draulic pilot pressure can be applied to the P1 and/or P2 port and the pressure ratio remains the same.

 


Integrated Accumulator Charging Valve/Pump Package

This is an integrated package featuring a MICO® Dual Accumulator Charging Valve and a Haldex W900 Gear Pump to accomplish the accumulator charging function. The accumulator charging valve controls the pressure in redundant accumulators used in two or more brake circuits. Brake circuits are protected from pressure spikes at startup by an internal pressure relief valve. Excess flow from the valve may be used for steering, cooling, or implement functions.

 


Hydraulic Brake System with ABS and Traction Control

MICO has been supplying manufacturers of off-highway equipment with reliable full power brake systems for over 30 years. MICO can now offer full power brake systems with ABS and traction control. Utilizing state-of-the-art technology with proven high-reliability components, the system can improve vehicle performance and operator safety. A system of this type provides shorter stopping distances, improved vehicle stability, and enhanced traction for vehicles driven under extreme operating conditions. The system is designed to handle up to 8 channels of ABS and traction control. Starting with a full power system that employs brakes, a tandem modulating pedal valve, an accumulator charging system and dual accumulators. The traction control system uses:
  • Speed sensors to monitor the speed of each wheel
  • Electronic control unit to send current to the traction control and ABS valves
  • Electrohydraulic traction control valves to pilot operate the tandem modulating pedal valve
  • Electrohydraulic ABS valves to proportionally control the pressure at the brakes
  • CAN bus using SAE J1939 protocols to communicate with the engine controller
  • Brake warning lamps for operator warning and diagnostics
  • ABS control switch to turn the ABS on or off and status lamps for operator information
  • Traction control switch to turn the traction control on or off and status lamps for operator information
The electronic control unit used in the system was developed specifically for applications in the harsh environment of mobile equipment. All inputs and outputs have been protected against shorts or over voltage and have built in diagnostics. The robust aluminum housing provides IP 65 protection and offers high immunity to electromagnetic disturbances.

MICO has been supplying manufacturers of off-highway equipment with reliable full power brake systems for over 30 years. MICO can now offer full power brake systems with traction control. Utilizing state-of-the-art technology with proven high-reliability components, the system can help maintain traction with the ground and reduce wheel spin in poor environmental conditions often experienced with off-highway vehicles. The system is designed to handle up to 8 channels of traction control. Starting with a full power system that employs brakes, a tandem modulating pedal valve, an accumulator charging system and dual accumulators. The traction control system uses:
  • Speed sensors to monitor the speed of each wheel
  • Traction control electronic control unit to send current to the traction control valves when wheel spin occurs
  • Electrohydraulic traction control valves to proportionally control the pressure at the brakes
  • CAN bus using SAE J1939 protocols to communicate with the engine controller
  • Brake warning lamps for operator warning and diagnostics

Hydraulic Anti-lock Brake System

For more than 30 years OEMs of off-highway equipment have chosen MICO Full Power Brake Systems to reliably stop their vehicles. Now you can rely on MICO to provide you with the first full power hydraulic brake system with ABS. Utilizing state-of-the-art technology, the hydraulic ABS (HABS) will provide shorter stopping distance with improved vehicle stability and control during aggressive braking situations. The system is designed to handle 8 channels, or less, of HABS control. Starting with a full power system that employs brakes, a tandem modulating pedal valve, an accumulator charging system and dual accumulators. The Anti-lock Brake System uses:
  • Speed sensors to monitor the speed of each wheel.
  • ABS electronic control unit to send current to the ABS valves when wheel slip occurs.
  • Electrohydraulic ABS valves to proportionally control the pressure at the brakes.
  • Pressure transducers and software algorithms for diagnostics.
In addition to these basic components, additional inputs and outputs can be added to the system. For example, keyed power or ABS on/off switch signals are typical. Outputs to drive the stop lamps, low traction and brake warning indicator lights can be added. Other inputs and outputs can be custom designed as required - including CAN communications based on SAE J1939, ISO 11783 or other protocols used in your system. The ABS controller was developed specifically for applications in the harsh environment of mobile equipment. All inputs and outputs have been protected against shorts or over voltage and have built in diagnostics. The robust aluminum housing provides IP 65 protection and offers high immunity to electromagnetic disturbances.
