Description

  • AndyMark EVO Shifter Short Keyed Shaft, StageA 2 Stage - 07.56:1 Ratio, StageB 2 Stage - 04.77:1 Ratio
  • Enhances shifting with 4-tooth dog mechanism
  • Accommodates two CIM or NEO motors
  • Features durable AMPCO® 18 Bronze dog gear
  • Supports multiple encoder options
  • Allows independent ratio selection

The AndyMark EVO Shifter Short Keyed Shaft, StageA 2 Stage - 07.56:1 Ratio, StageB 2 Stage - 04.77:1 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 performance. The gearbox is shipped assembled, though motors are not pre-installed.

The design improvements include a robust 1/8" diameter shoulder screw and a dog gear made from AMPCO® 18 Bronze, which provides increased strength and lubricity compared to previous models. The gearbox features a super-strong shift block assembly with a larger bearing and threaded steel housing, enhancing durability. The input stage utilizes 32 DP gears and a 15 tooth pinion gear, achieving a high 85:15 first stage reduction. Users can independently select high and low ratios, allowing for customized performance adjustments.

The EVO Shifter employs a pneumatic shift method, utilizing a spring-extend pneumatic cylinder for reliable operation even under varying conditions such as acceleration or deceleration. 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 also offers more encoder options, including the US Digital E4T encoder, enhancing its adaptability for different applications.

Note: Ensure proper greasing and break-in procedures are followed for optimal performance and longevity of the gearbox.
