AndyMark EVO Shifter 4 RedLine (4in. Wheel Version)
Optimizes performance with 4-inch wheels
Features 2-speed, shift-on-the-fly gearbox
Enhances reliability with improved dog shifting
Accommodates up to four 775 motors
Includes aggressive weight reduction
The AndyMark EVO Shifter 4 RedLine (4in. Wheel Version) represents the latest advancement in shifting transmission gearboxes for competitive robotics. This two-speed, shift-on-the-fly gearbox is designed to accommodate up to four 775 class motors, such as the AndyMark RedLine Motor. It features an enhanced 4-tooth dog shifting mechanism, which provides increased strength and reliability over previous models. The gearbox is optimized specifically for driving 4-inch diameter wheels, ensuring efficient performance in competitive environments.
This version of the EVO Shifter is equipped with a pneumatic shift method, utilizing a spring-extended PHD pneumatic cylinder. This allows for seamless shifting even while the robot is accelerating, pushing, or decelerating. The gearbox is shipped assembled, though the motors are not pre-installed. Notably, the gearbox includes a 2 Stage EVO Shifter Long Hex Output Shaft, which is integral to its operation.
Significant improvements have been made in this model, including the use of AMPCO® 18 Bronze for the dog gear, which offers enhanced lubricity for smoother shifting. The shift block assembly has been reinforced with a larger bearing and steel housing, and the input stage now uses 32DP gears for an effective first stage reduction. Additionally, the gearbox features aggressive weight reduction and improved encoder options, making it a versatile choice for various robotic applications.
Note: It is crucial to use this gearbox configuration only with 4-inch wheels to prevent potential damage to the motors. For larger wheels, an external reduction device is recommended.
