Curtiss-Wright Deploys Cutting-Edge Rapid Prototyping Electronic Throttles For New Polaris RZR Vehicles

As vehicle volumes increase, Polaris Industries Inc. (NYSE: PII) – a leading designer and manufacturer of innovative, high quality off-road vehicles (ORVs), including all-terrain vehicles (ATVs), snowmobiles, motorcycles and on-road electric/hybrid powered vehicles – is opting for Williams Controls (a legacy brand of Curtiss-Wright) throttles as part of its decision to move away from conventional push/pull mechanical systems to electronic control.

Engineering teams from both companies worked together for almost eighteen months to re-engineer an existing pedal design, with the resulting electronic pedal needing to be sized and ergonomically shaped to suit the compact in-cabin dimensions of the all-new RZR XP 1000. During the product development phase, Curtiss-Wright engineered a new spring design and, using its in-house rapid prototyping facilities, an altered lever arm.

The updated specifications for the new electronic throttle also included the use of an integrated, non-contacting Hall-effect sensor providing two independent linear output signals proportional to pedal position. This sensor provided feedback directly to Polaris’ latest throttle management system – credited as providing the fastest acceleration, highest top speed and flattest torque curve in the industry – to provide much-improved control.

What seemed like relatively simple design changes to the existing pedal actually required a complete revalidation of the custom pedal to ensure its suitability for both Polaris applications. This included testing it for both U.S. and European market requirements and a series of environmental assessments.

Despite some of the harshest tests ever carried out on its products – including corrosion resistance and ice water shock tests – the pedal out-performed the requirements of both companies. In fact, for the corrosion resistance test conducted in a salt fog chamber, the custom pedal far exceeded Curtiss-Wright's own 96 hour requirement and easily met the Polaris requirement of 336 hours. Upon completion of the environmental testing process, Curtiss-Wright was able to provide Polaris with working samples for pre-production and field-testing, which has been completed successfully.

Commenting on the stringent testing requirements, Senior Vice President & General Manager of Curtiss-Wright’s Industrial division Kevin Rayment explains that, given the conditions Polaris vehicles have to endure, they are delighted with the results. “It’s not unusual for these recreational vehicles to be found driving through swamps or in muddy water up to the driver’s waist, so to not just pass but exceed these somewhat unique requirements is a testament to our design, engineering and manufacturing processes.”
