Xue Rongsheng, a researcher at the Center for Intelligent Transmission Engineering Technology Research at Southwest University, said that unlike existing electric vehicles, such transmissions do not have synchronizers, shift clutches, shifting brakes, etc., but rather microcomputers, automatic transmissions, sensors, and inheritance. Electronic circuit and other components. It has the wisdom of human beings. The sensor can automatically sense different road conditions such as uphill, downhill, start, and taxi, and automatically shift gears according to the driving speed and resistance. At the same time, the sensor “tells†the relevant information to the central controller, synchronizes the engine properly, produces the required drive torque and speed, and any speed can be easily “fixed†with a speed control handle.
According to Xue Rongsheng, this intelligent automatic transmission can shift gears without cutting power, thus saving energy consumption. When climbing, accelerating, and starting, the intelligent transmission can control the motor to output the proper torque by sensing the associated parameters such as the rotational speed, driving resistance, and road adsorption force, thereby controlling the wheel speed to the optimal range and reducing the wheel speed. The power consumption also improves the traction performance of the vehicle.
It is understood that compared with the existing electric vehicles, this intelligent automatic transmission can save energy by 10% - 20% and reduce emissions by 20% - 30%. Because the climbing ability exceeds 12 degrees, it can be used not only in plain areas, but also in mountainous and hilly areas.
Animals Puzzle Mat is a educational puzzle mat, a learning tool, and a cushioned play area all rolled into one. The different animals shapes pop out to teach basic animal and color recognition; and the cushioned pieces provide a soft play area, making it perfect for playrooms, nurseries, classrooms, gyms, and more. Made of easy-to-clean EVA foam, the squares stack nicely together for easy transport.
Interchangeable pieces allow kids to develop gross motor skills, hand-eye coordination, and visual sensory growth, large, cushioned, and colorful puzzle pieces are very safe, not only for your children but they also protect your floors against damage.
