The invention provides a resistance and rotating energy combined system. The resistance and rotating energy combined system comprises gas storing cylinders, first resistance devices, a second resistance device, a steam turbine, and a resistance pedal structure, wherein the gas storing cylinders are arranged at the lower part of a vehicle; the first resistance devices are arranged on a rear axle of the vehicle, and generate resistance for a half shaft of the rear axle; the second resistance device is arranged on an exhaust pipe of a motor of the vehicle; the steam turbine is connected with a gearbox of the vehicle, and is used for providing rotating assisting power for a transmission shaft; the resistance pedal structure is arranged in a driving cabin of the vehicle; the first resistance devices and the second resistance device separately communicate with the gas storing cylinders; the gas storing cylinders are connected with the steam turbine; and the first resistance devices and the second resistance device are respectively connected with the resistance pedal structure. According to the resistance and rotating energy combined system disclosed by the invention, through the first resistance devices and the second resistance device, the resistance that the vehicle travels down a slope is increased, so that the using frequency of a brake system of the vehicle is reduced, the brake wear is reduced, the temperature rising of a brake pot is controlled, the situation of cooling through spraying water is avoided, and damage and pollution to a road are reduced; and gas in the gas storing cylinders, stored by a compressor and the exhaust pipe, drives the steam turbine to provide assisting power for the rotation of the transmission shaft of the vehicle, so that during upslope, the burden of the engine is reduced, and energy resources are saved.
