    To enhance the quality of power generation, a magnetorheological transmission device (MRTD) has been developed for traveling power generation. This design facilitates precise speed regulation and ensures consistent output. A simulation model, along with a corresponding experimental system, has been established to evaluate the performance of the MRTD. The simulation results indicate that, with a cooling water temperature of 25 °C, a cooling water gap of 1 mm, and a slip power of 5 kW, the temperature within the transmission space remains within the normal operating range for magnetorheological fluids after achieving a steady state. Notably, there is no observed expansion or deformation of the core transmission components under high-temperature conditions. Moreover, results from the experimental system demonstrate that, under operational conditions of 5 kW and a flow rate of 0.72 m³/s, the maximum temperature at the measurement point increased by 83 °C over a period of 1250 seconds, ultimately reaching a peak temperature of only 95.2 °C. The temperature rise curve exhibits a tendency to stabilize, suggesting that the designed transmission device can operate reliably at a slip power of 5 kW and is suitable for providing constant-speed power output during vehicle operation.
