Pailton Engineering reveals the results of a 56-week-long test program on its latest generation three bevel Box. Findings showed that after a sustained period of submersion, salt, and grit exposure at temperatures as low as -40°C, no trace of water had entered the vital component and the part maintained its smooth operation. This has huge implications for buses, trucks, and military vehicles in sub-zero climates.
Bevel boxes are a pivotal component of a steering system, transmitting torque through 90° to provide a compact steering system package. The Generation three bevel box was launched last year, to improve on previous designs, adding new design features. It boasts upgraded sealing capabilities and reduced torque characteristics.
To complement this, Pailton also sent the bevel box to external testing facilities. Here, it was determined to meet ASTM B117, an internationally recognized standard of salt testing. It also was shown to conform with ingress protection codes IP66 and IP67.
Low temperatures can bring about issues with the viscosity of the fluid in lubricated components. However, the low temperature lubrication selected for the generation three bevel box can handle a temperature range of -40°C to 80°C, maintaining its low friction capabilities throughout the vehicle’s lifespan. This means the component has a much lower running torque of 30 Ncm, resulting in minimal steering effort to the driver.
The bevel box design will provide increased protection, reducing the effects military vehicles, buses and coaches face in a changing environment, such as across the cold regions of the United States, Europe and Canada.
As well as low temperatures, Pailton Engineering can manufacture this bevel box to the specific requirements for any vehicle application, using the latest technology in manufacturing and testing will extend the product life.
