The types of steering wheels can be divided into single steering wheel, double steering wheel, three steering wheels and four steering wheels.
Introduction of single steering wheel:
Single steering wheel is widely used in early vehicles, and the inner diameter space of single steering wheel is very convenient compared with now, but with the application of power steering, single steering wheel has ended its historical mission.
Introduction of double steering wheel:
It was used in early vehicles, but it is difficult to support and install airbags with dual steering wheels, so this part is used much less.
Introduction of three steering wheels and four steering wheels:
Nowadays, it is most used in cars, because airbags can be installed inside, which is more convenient to use.
