[0003] In the vehicle teaching process, for the driving school students who have just come into contact with motor vehicles, their driving operation is not yet mature, and it is inevitable that various possible damages to the motor vehicle or the driver may be caused by improper operation during the learning process. Accidents that affect safety

At the same time, the designer of the coach car has been equipped with a secondary rearview mirror, a secondary brake pedal, a fire extinguisher, a secondary accelerator pedal, and a secondary clutch for the safety of the motor vehicle and the students. Pedals and some other safety protection devices, but with the status quo of such a coach car, there are still major safety hazards: on the one hand, in an emergency, due to the lack of experience of the trainees, they cannot control the correct direction in time, resulting in even following The coach can take emergency brakes on the coach car in time, but still cannot control the driving direction of the car. In such a situation, it is very likely that traffic accidents cannot be avoided, causing safety problems for the motor vehicle and the people in the car; On the one hand, most of the steering shafts of coach cars in the prior art are rigidly connected to the steering gear.
