Description

  • AndyMark EVO Shifter am14u Family Shaft, StageA 3 Stage - 09.54:1 Ratio 2:1, StageB 3 Stage - 09.54:1 Ratio 2:1
  • Features two-speed, shift-on-the-fly design
  • Offers improved 4-tooth dog shifting method
  • Accommodates two CIM or NEO motors
  • Incorporates robust AMPCO® 18 Bronze dog gear
  • Includes aggressive weight reduction features

The AndyMark EVO Shifter am14u Family Shaft, StageA 3 Stage - 09.54:1 Ratio 2:1, StageB 3 Stage - 09.54:1 Ratio 2:1 represents a significant advancement in shifting transmission gearboxes. This two-speed, shift-on-the-fly gearbox is designed with an improved 4-tooth dog shifting method, allowing for seamless transitions between speeds. It accommodates motor inputs from two CIM or NEO motors and can be configured with either two or three interior stages, offering flexibility in performance. The gearbox is shipped assembled, though motors are not installed, even if included in the order.

The EVO Shifter incorporates several enhancements over previous models, including a robust 1/8" diameter shoulder screw and a dog gear made from AMPCO® 18 Bronze, which provides added 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 option to swap ratios as needed. The gearbox also supports various encoder options, including the US Digital E4T.

Aggressive weight reduction features have been integrated into the gears and plates, and the gearbox can be mounted to an AM14U family chassis or a 2"x1" box tube frame. The pneumatic shift method utilizes a spring-extend pneumatic cylinder, allowing shifts to occur even during acceleration or deceleration. The gearbox requires periodic greasing for optimal operation and longevity, with a recommended break-in period before applying grease. The encoder ratio for two-stage versions is 3:1, ensuring precise control and feedback.

Note: Ensure proper installation of the pinion gear using Red Loctite 271 and follow safety guidelines when handling the gearbox components.
