Bicycle Universal Continuously Variable Transmission

Advanced Transmission Systems Holdings (ATSH) has developed a novel Continuously Variable Transmission (CVT) suitable for integration into a range of technologies in a number of industries including the mobile equipment, automotive, and industrial sectors. A Continuously Variable Transmission (CVT) is a transmission that can change steplessly through an infinite number of effective gear ratios between maximum and minimum values.

Emerging Innovation Category Finalist, WA Innovator of The Year 2018- Advanced Transmission Systems Holdings – Universal Continuously Variable Transmission (CVT). An ultra-narrow stepless transmission featuring very high gear ratios and ranges, offers the opportunity to drastically improve the performance of many vehicle and industrial equipment technologies.

The base functionality of the Company’s VDP-CVT is identical to that of a conventional VDP-CVT. A key difference is the makeup of the pulley sides which are segmented into separate ring sectors rather than being made of a single continuous surface element.


The working principle of our segmented bicycle VDP-CVT is based on a series of equal width pulley ring sectors moving into contact with the V-belt from a retracted position such that only the pulley diameters needed for a chosen gear ratio are engaged, while other diameters are out of the way of the belt when it is moved between gear settings.via/read more: treadlieengineering
