The working process of the invention adopting the design is as follows: when the automobile normally runs, an exerciser slowly treads on an accelerator pedal, a push rod slowly moves downwards to compress a spring and drive an upper piston to move downwards, hydraulic oil above a partition plate flows to the lower part of the partition plate through an oil through hole to move a lower piston downwards, and therefore an accelerator connecting rod moves downwards to achieve the oil supply effect; the spring is compressed between the upper mounting disc and the lower mounting disc to cause the upper mounting disc to move towards the lower mounting disc, so that the upper connecting rod and the lower connecting rod rotate to enable the support rod to move towards the direction of the inner wall of the oil cylinder, but the accelerator pedal is slowly trodden by an exerciser, so that trodden force is mainly used for driving hydraulic oil in the oil cylinder to smoothly flow through the oil through hole, the compressed length of the spring is smaller, the moving distance of the support rod is smaller, the friction block cannot be in contact with the inside of the oil cylinder, and the push rod can smoothly move downwards to smoothly feed oil.
When an accident happens, an exerciser steps on the accelerator in a hurry manner, the upper piston is pushed by larger thrust to push hydraulic oil in the oil cylinder, but the oil through hole in the partition plate is limited in size, so that a large amount of hydraulic oil cannot pass through in a short time, the upper piston cannot move downwards for a larger distance in a short time, the treading force of the exerciser is mainly used for compressing the spring, the compressed length of the spring is longer, the distance from the upper mounting plate to the lower mounting plate in an even east is larger, the rotating radian of the upper connecting rod and the lower connecting rod is larger, the resisting rod moves towards the direction of the inner wall of the oil cylinder, the friction block is tightly resisted on the inner wall of the oil cylinder, and after the friction block is tightly resisted on the inner wall of the oil cylinder, the upper connecting rod and the lower connecting rod cannot rotate, so that the upper piston cannot move and oil cannot be smoothly supplied; meanwhile, the operator is guided to step on the auxiliary brake pedal, a piston rod connected with the auxiliary brake pedal moves downwards, a piston rod of the cutting ring moves downwards through the transmission of the hydraulic transmission mechanism and pushes the cutting ring to move downwards, and meanwhile, an accelerator piston rod moves upwards to jack up the accelerator pedal; the cutting ring moves downwards to enable the cutting ring to be disconnected with the driving column, so that the driving shaft is disconnected with the main steering shaft, the driving shaft cannot control the steering of the main steering shaft, the main steering wheel cannot control the direction of the automobile, and therefore instructors cannot be interfered by the main steering wheel when operating the auxiliary steering wheel to control the direction of the automobile.
The invention has the advantages that the design is adopted: in emergency, after the instructor steps on the auxiliary brake pedal, the structure is cut off to disconnect the connection between the driving shaft and the main steering shaft, so that the instructor cannot control the direction through the main steering wheel and controls the direction through the auxiliary steering wheel, and the condition that two persons control the steering wheel simultaneously to cause the loss of control of the automobile is avoided; when the trainer rushes to step on the accelerator in a hurry process, the emergency locking mechanism acts, so that the trainer cannot smoothly step on the accelerator, the risk of the sudden acceleration of the automobile is reduced, and the possibility of accidents is reduced.
