Force application large ring converter, transmission system and automobile

The invention provides a stress application large ring converter which comprises a power output shaft and an inner ring support connected with the power output shaft through a connecting piece, and further comprises a stress plate and an outer ring support, an annular installation space is formed between the stress plate and the inner ring support, and the stress plate is installed between the inner ring support and the outer ring support. The air compressor has the advantages that the stress plate is arranged on the inner ring support, air pressure difference generated when high-pressure air passes through the stress plate can drive the power output shaft to rotate, meanwhile, the farther the stress plate is away from the power output shaft, large torque can be generated by small force, and the power output shaft can be driven to rotate. The larger the force generated when the stress plate rotates is, the maximum energy conversion rate is achieved, airflow power can be converted into mechanical energy to the
