Description

Technical Field

[0001] The utility model belongs to the technical field of automobile teaching aids, and more specifically, relates to an automobile steering, braking and suspension system teaching aid. Background Art

[0002] The braking system and the steering suspension system are related to vehicle safety and need to be maintained and repaired frequently. Therefore, a large number of maintenance personnel familiar with their mechanical structures and working principles are required to carry out daily maintenance and fault repair. In the past, maintenance materials and training materials were mainly in paper form, with a single and non-intuitive information transmission method. Using real vehicles for practical training is costly, and a large number of surrounding parts of the vehicle need to be removed to understand the complete structure, which is extremely time-consuming. Therefore, it is necessary for engineers who accurately master the structure of the braking system and the steering suspension system and lecturers who understand the training teaching process to cooperate to complete the design of the training platform for the braking system and the steering suspension system.

[0003] At present, most of the teaching aids used on the market simplify the specific devices of automobile steering, braking and suspension, only retain the key operation parts and transmission parts, and connect electronic components to monitor their operations throughout the process. Chinese Patent with Publication No. CN103310684B discloses an integrated teaching and training platform for an automobile active suspension and an electric steering system, including: a bench, original vehicle parts of an automobile active suspension system and an electric steering system, a control and display panel, a circuit detection board, an integrated teaching computer system and a digital display module. The original vehicle parts of the automobile active suspension and electric steering systems are fixed in a movable steel bench. One end of the bench is connected with a control and display panel, and the other end of the bench is connected with a circuit detection board. Circuit diagrams of the automobile active suspension and electric steering systems are drawn on the circuit detection board. An integrated teaching computer system is installed on the right side of the circuit detection board, and a digital display module is installed above the circuit detection board. It can perform operations, fault settings and fault demonstrations, enabling students to more easily master the structure and working process of the automobile active suspension and electric steering systems, achieving the purpose of facilitating teaching for teachers and learning for students.

[0004] However, the Chinese Patent with Publication No. CN103310684B only shows some key parts of the automobile suspension and steering systems, which only enables the taught personnel to intuitively see the working principle, but cannot enable them to come into contact with the real configuration environment on the automobile, and the difference from the actual operation environment is relatively large, so the teaching results on this teaching aid will be greatly reduced. Therefore, a teaching aid for an automobile steering, braking and suspension system is needed to truly restore the operation environment on the automobile and improve the teaching efficiency.
