Product Overview

This shift-on-the-fly gearbox, uses a dog gear shifting method. Motor input accepts two CIM motors, or two AM Planetary Gearboxes or a combination of either (both not included). The output shaft is a 1/2" 4140 steel shaft with a 1/8" keyway.
Key Features:
  • The output shaft is centered on the gearbox
  • CIM motor inputs centered on the gearbox
  • The Sonic Shifter is lighter than the AM Shifter and Super Shifter designs
  • Wider variety of gear ratio options available
Shift Style:
Two shifting methods are available for the Sonic Shifter. The pneumatic method is much stronger and faster than the servo method.
  • Pneumatic:
    • A pneumatic cylinder, Bimba model 04-0.5-DP, 3/4" bore x 1/2" stroke, (not included) shifts between high and low gear. This cylinder mounts with a 5/8-18 nut (not included). This is a strong, fast method of shifting, lasting under 0.5 seconds and pushing with 26 pounds of force (if using 60 psi). This pneumatic shift can be done while a robot is accelerating.
  • Servo:
    • A Servo Shifting hardware pack is available (am-xxxx), but not included with this product.
    • A Hi-Tech Servo, model HS-422HD is included in am-xxxx, using an actuation fork to shift between the 2 gear settings. This is a slow, weaker method of shifting (compared to pneumatic), taking 1.5-2 seconds and pushing with up to 8.5 pounds of force. A robot driver may need to back off of the throttle to let a servo shift gears while moving.
Total Weight: approx. 3.5 lbs., with pneumatic cylinder installed
