On a level road, the spoiler extends downwards at a speed of 60 km/h or more. It guides the airflow over the vehicle in such a way that no uncontrolled turbulence occurs underneath the vehicle. In the case of a pick-up truck or SUV, this means a considerable improvement of the aerodynamics and therefore less fuel consumption. If the speed drops below 60 km/h or the road suddenly becomes uneven, the front spoiler is pulled upwards.
In the development phase and during validation, the lead screw drive was exposed to unusual kinds of stress. Test runs in Alaska in winter at temperatures down to -40°C, salt spray tests to test resistance to corrosion, also severe stress due to slush and spray water. Then in summer, the heat and dust in the Nevada deserts The lead screws and nuts from igus® withstood all of this, without any maintenance or additional lubrication.
The patented dryspin high helix thread technology was developed by igus in 2013 and offers numerous advantages compared to conventional high helix threads. Due to the flat thread angle, it converts the exerted power efficiently into a translational movement. With properties and shapes matching the polymer nut and lead screw, dryspin thereby provides an even longer service life and more efficiency for high helix threads. Due to the rounded tooth geometry, the contact area between lead screw and nut is reduced, and the lead systems operate quietly and without vibration under load.
The larger spaces between the individual dryspin threads result in a higher share (factor 1.3) of tribologically optimised polymer in the threads. More wear-resistant material and higher levels of efficiency are crucial for a service life that is up to five times longer compared to conventional high helix threads.
Take advantage of our machining service - we manufacture ready-to-fit lead screws based on your requirements. For this, use our lead screw configurator or send us a drawing. We will then provide a quotation.
The expert can quickly help engineers find the right lead screw system part for their application and will also predict service life.
The configurator enables engineers to quickly find the right lead screw and machine the pins from both sides. The application generates a dimensioned drawing of the configuration for you.
