Description

  • AndyMark EVO Shifter am14u Family Shaft, StageA 3 Stage - 09.54:1 Ratio 2:1, StageB 3 Stage - 12.00:1 Ratio 2:1
  • Enhances shifting with 4-tooth dog gear mechanism
  • Supports two CIM or NEO motors
  • Offers 2 or 3 stage configuration options
  • Includes pneumatic cylinder for on-the-fly shifts
  • Constructed with AMPCO® 18 Bronze for durability

The AndyMark EVO Shifter am14u Family Shaft, StageA 3 Stage - 09.54:1 Ratio 2:1, StageB 3 Stage - 12.00:1 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 mechanism, allowing for seamless 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 output shaft selection. The gearbox is delivered assembled, though motors are not pre-installed.

The EVO Shifter introduces several improvements over previous models, including a robust 1/8" diameter shoulder screw and a dog gear made from AMPCO® 18 Bronze, which provides enhanced strength and lubricity. The shift block assembly is reinforced with a larger bearing and threaded steel housing, ensuring durability. The input stage features 32 DP gears and a 15-tooth pinion gear, facilitating a high 85:15 first stage reduction. Users can independently select high and low ratios, with the ability to swap ratios as needed, and additional encoder options are available.

The gearbox is designed with aggressive weight reduction features and can be mounted to an AM14U family chassis or a 2"x1" box tube frame. It employs a pneumatic shift method powered by a spring-extend pneumatic cylinder, allowing for shifting during acceleration, pushing, or deceleration. The gearbox's weight ranges from 2.9 to 3.5 pounds, depending on the stage configuration.

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