Self-aligning steering wheel simulation device for automobile driving training apparatus

Abstract

The invention discloses a self-aligning steering wheel simulation device for an automobile driving training apparatus. The simulation device has the structure that: a steering wheel is fixed with a steering shaft; the steering shaft is connected with a screw rod by a reduction gearbox; a screw rod nut and the screw rod form a transmission pair; the screw rod is supported by a frame; two springs are respectively fixed on the inner wall of the frame; the screw rod nut is provided with a connecting rod; two ends of the connecting rod are fixed at a central position of the two springs respectively; one end of the connecting rod is connected with a displacement sensor to transmit a steering angle of the steering wheel to a signal processing system of the automobile driving training apparatus in real time; simultaneously the springs are compressed and stretched to accurately position the steering angle of the steering wheel and a position of a wheel. After steering force is removed, the steering wheel is automatically and steadily aligned without a rebound phenomenon. When a trainee operates the device, the steering wheel generates actual force feeling feedback with the change of a rotation angle. Simultaneously, the device has the advantages of simple installation, convenient maintenance, high environmental protection performance and higher practical value.

Description

technical field [0001] The invention relates to a steering wheel device with a real sense of force in an automobile driving training simulator. Background technique The airport fire truck is a fire-fighting vehicle dedicated to fighting aircraft fires. As the first priority of civil aviation safety, once an aircraft fire occurs in Hong Kong, the airport fire truck must rush to the scene to control the fire as soon as possible to ensure the safety of passengers to the greatest extent. It is precisely because of the special working characteristics of airport fire trucks that fire truck drivers have higher technical requirements than ordinary motor vehicle drivers. The airport fire simulator is designed to train airport fire truck drivers. During the simulation training process, the driver needs to perceive the motion state of the vehicle through vision, hearing, and physical sensations. One of the important feedback information is the real force feedback from the steering ...
