The AndyMark EVO Shifter Short Keyed Shaft, StageA 2 - 16.37:1 Ratio, StageB 2 - 06.00:1 Ratio represents a significant advancement in shifting transmission gearboxes. This two-speed, shift-on-the-fly gearbox incorporates an enhanced 4-tooth dog shifting mechanism, allowing for seamless transitions between speeds. It is compatible with two CIM or NEO motors, and can be configured with either two or three interior stages, offering flexibility in output shaft selection. The gearbox is delivered assembled, though motors are not pre-installed.
Several improvements distinguish this model from previous iterations. The dog gear now features four dogs per face, enhancing strength and durability. The use of AMPCO® 18 Bronze for the dog gear material provides added lubricity, ensuring smooth shifting. A robust shift block assembly with a larger bearing and threaded steel housing is included, contributing to the gearbox's overall resilience. The input stage utilizes 32 DP gears and a 15-tooth pinion gear, facilitating a high first stage reduction. Users have the autonomy to select their preferred high and low ratios, with the ability to interchange them as needed.
The gearbox supports various encoder options, including the US Digital E4T and the CTRE SRX mag encoder. Weight reduction features have been meticulously integrated into the gears and plates, and the design allows for easy disassembly and reassembly without concern for gear orientation. The gearbox can be mounted to an AM14U family chassis or a 2"x1" box tube frame using existing mounting plate holes.
The EVO Shifter employs a pneumatic shift method, powered by a spring-extend pneumatic cylinder, enabling shifts during acceleration, pushing, or deceleration. This design ensures continued operation in Ratio A even if air pressure is lost. Proper greasing is essential for optimal performance and longevity, with a recommended break-in period before applying grease to the spur gears.
