Moveero Profi-Flex: Keeping agriculture moving at speed

According to off-highway wheels and hub systems manufacturer moveero, its high-speed Profi-Flex tractor wheel addresses the issues of runout that can occur on manually adjustable track wheels when used on high-speed applications. The company says this results in high levels of comfort, ride quality and tractor performance.

The standard for tractors that are approved for speeds of 31 mph (speed rating B) and above requires high spot marking of the wheel and low spot marking of the tyres. This ensures the tyre is positioned accurately and so minimises runout and optimises ride comfort and performance. However, to suit different operational requirements, manually adjustable wheels enable the disc to be moved to change the track settings and, in these circumstances, it is vital that when it is refitted, the disc is not rotated and the alignment is not altered, as this could have a significant impact on runout.

To address this issue, moveero’s Profi-FlexHS wheel incorporates integrated centring pins in the spacers, guaranteeing that the disc and rim are correctly re-aligned when wheel track settings are being changed. This patented solution uses a single alignment pin which ensures that the disc must be re-fitted in the correct position when the track spacing has been changed.

Wheel cannot be assembled incorrectly

“With tractor speeds constantly increasing, the issue of run-out, or “wheel wobble”, is ever more important, as the faster the tractor’s speed, the more pronounced the issue becomes,” comments John Madsen, moveero’s engineering director. “Profi-FlexHS addresses this problem, ensuring that whenever the track setting is changed, the disc is replaced in the correct alignment with the wheel and that the correct tolerances are maintained. Having seen other systems where the centring feature is an extra component that can easily get lost, our engineers developed a ‘Poka Yoke’ solution, to ensure that the wheel cannot be assembled incorrectly.

“Our solution is simple and straightforward, ensuring that the manual adjustment of a tractor’s track settings can be completed efficiently and accurately, every time. As a result, the ride quality, comfort levels and tractor performance are maintained at the highest levels.”
