about Cross Drive Transmission Test Dynamometer
Roltamax's A Cross Drive Transmission Test Dynamometer is a specialized rig for testing dual-output transmissions, common in tracked military vehicles (like tanks), that simulates real-world conditions by applying independent loads to each output shaft to test performance, efficiency, steering, braking, durability, and control systems, crucial for validating complex propulsion systems beyond simple single-output dynos. These systems use load absorbers (dynos) on both outputs, allowing for precise control of torque, speed, and power to mimic maneuvers like turning, where one track speeds up and the other slows down.
Dual Outputs: Unlike standard dynos, they have two separate output shafts, each connected to a load unit (dynamometer).
Simulated Steering & Braking: Load units simulate track resistance, enabling testing of steering and braking functions by varying power to each output, crucial for tracked vehicles.
Performance Testing: Measures input/output torque, speed, power, and efficiency under varying loads.
Durability & NVH: Simulates prolonged use to find failure points and checks for noise, vibration, and harshness (NVH).
Control System Validation: Evaluates the electronic and hydraulic controls for shifting and steering.
Versatility: Can test various transmissions, including those for M1 Abrams tanks, M113 APCs, Bradley Fighting Vehicles, and other heavy equipment.
Replace Field Testing: Allows for comprehensive testing in a controlled lab environment, saving time and cost.
Validate Complex Systems: Essential for military and heavy-duty vehicles where precise control of dual outputs for steering is vital.
Ensure Reliability: Identifies potential issues and verifies performance under extreme stress before deployment.
