Dana Corp.’s Commercial Vehicle Systems group has enhanced its Dana Spicer Tire Pressure Control System (TPCS) with a new integrated Driver Display Module (DDM) that, in conjunction with new dash-mounted rocker switches,
simplifies the selection of tire pressures under varying load and terrain conditions.
“These additions have resulted in a more convenient and user-friendly way to select the best tire pressure for vehicles, particularly mixers, engaged in a variety of on- and off-highway applications,” said Jim Beverly, chief engineer for Advanced Chassis Control Systems for Dana’s Commercial Vehicle Systems group. “In addition, the smaller foot-print of the DDM and rocker switch interface provides much more flexibility for OEMs in regards to dash lay-outs.”
As the only system of its kind that is available as a factory-installed data book option, the Spicer Tire Pressure Control System is available on most makes and models of vocational heavy-duty trucks manufactured in North America. It is also the only system with air seals built into the axles that eliminate the need for external air lines for reliable, trouble-free performance.
The newly designed driver interface supports two load modes – loaded and unloaded – and three terrain selections – highway, off-highway and emergency. The highway mode permits high-speed travel on paved surfaces; off-highway allows for efficient operation on unpaved surfaces; while the emergency mode provides extremely low tire pressures to tackle exceptionally poor terrains and grades that might otherwise be impossible to negotiate without assistance. The six separate settings are designed to allow for smooth, trouble-free navigation over a wide variety of road surfaces and load conditions.
In addition to communicating and displaying operating conditions such as the selected load and terrain, the new DDM unit can display tire pressure by axle group, as well as over-speed and low tire (run-flat) operation. In the event the system recognizes a fault condition, the DDM will report problem areas to help bring about fast, accurate solutions.
