Description

  • AndyMark EVO Shifter am14u Family Shaft, StageA 3 Stage - 12.00:1 Ratio 2:1, StageB 3 Stage - 45.33:1 Ratio 2:1
  • Incorporates enhanced 4-tooth dog shifting for smooth transitions
  • Compatible with CIM or NEO motors, offering performance flexibility
  • Mounts to AM14U chassis or 2"x1" tube frame, ensuring versatility
  • Includes pneumatic shift for continuous operation amid pressure loss
  • Offers aggressive weight reduction for improved efficiency

The AndyMark EVO Shifter am14u Family Shaft, StageA 3 Stage - 12.00:1 Ratio 2:1, StageB 3 Stage - 45.33:1 Ratio 2:1 represents a significant advancement in shifting transmission gearboxes. This two-speed, shift-on-the-fly gearbox incorporates an enhanced 4-tooth dog shifting method, allowing for smooth and efficient transitions between gears. It is compatible with two CIM or NEO motors and can be configured with either two or three interior stages, offering flexibility in performance. The gearbox is designed with robust materials, including AMPCO® 18 Bronze for the dog gear, which provides added strength and lubricity compared to previous stainless steel designs.

The EVO Shifter features a super-strong shift block assembly with a larger bearing and threaded steel housing, enhancing its durability. The input stage utilizes 32 DP gears and a 15-tooth pinion gear, achieving a high first stage reduction of 85:15. Users have the ability to independently select high and low gear ratios, providing customization options for various applications. The gearbox also supports multiple encoder options, including the US Digital E4T, and offers aggressive weight reduction features for improved efficiency.

Mounting options are versatile, allowing the gearbox to be attached to an AM14U family chassis or a 2"x1" box tube frame. The pneumatic shift method, powered by a spring-extend pneumatic cylinder, enables gear shifting even during acceleration or deceleration. This ensures continuous operation in the event of air pressure loss, as the system defaults to Ratio A.

Note: Proper greasing is essential for optimal performance and longevity of the gearbox. It is recommended to run the gearbox for 30 minutes without grease to allow the gear teeth to wear in before applying grease periodically to the spur gears.
