FR8AT-500
The Shengrui FR8AT-500 Longitudinal Automatic Transmission has a maximum input torque of 500 N.m, a maximum input speed of 6000 RPM, and a gear ratio spread of 7.8. It supports both two-wheel drive and four-wheel drive layouts, and can be expanded to P2 hybrid variant FR8HT-500.(The transmission can be matched with gasoline and diesel engines; dual overdrive gears are adopted to optimize fuel economy; the hybrid derivative FR8HT-500 is integrated with high-voltage motor modules for new energy vehicles.)
In the detailed model name, “FR” stands for Front-engine Rear-wheel drive layout. The number “8” represents 8 forward speed gears. “AT” means Automatic Transmission. The suffix “500” indicates the maximum rated input torque of 500 N.m. Derivative suffix “HT” denotes P2 hybrid variant with integrated high-voltage motor module.
