Device for demonstrating and adjusting positioning parameters of automobile steering wheels

Abstract

The invention discloses a device for demonstrating and adjusting positioning parameters of automobile steering wheels. The device comprises a frame and wheels, wheel forks are respectively connected to inner sides of the front wheels and connected with middles of kingpins by front wheel camber angle adjusting devices, the lower end of each kingpin is hinged with one end of a fixing ball-joint connecting rod, the other end of each fixing ball-joint connecting rod is connected with a support plate, the upper end of each kingpin is connected with the corresponding support plate by a kingpin inclination angle adjusting device, each support plate is connected with a caster angle indicator board by a kingpin caster angle adjusting device, the caster angle indicator boards are fixed onto the frame, a steering mechanism is disposed on the frame, and front wheel toe-in adjusting devices are arranged in the steering mechanism. By the device, the complicated and abstract positioning parameters of the steering wheel become simple and specific, so that a teacher can visually demonstrate the principle, the formation process and the adjusting method of the positioning parameters of the four steering wheels of an automobile, and a teaching effect is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical devices and transportation, and in particular relates to a demonstration adjustment device for positioning parameters of steering wheels of automobiles. Background technique [0002] People pay more and more attention to the safety and comfort of automobiles during driving. In order to ensure the stability of the straight-line running of the car and the ease of manipulation, reduce the wear of tires and other parts, reduce fuel consumption, and enable the steering wheel to automatically return to the center, the steering wheel, steering knuckle and front axle are in harmony with the car. The installation of the rack should maintain the correct installation position. This installation with certain relative positional relationship is called steered wheel alignment, also known as front alignment. Front alignment comprises caster angle, kingpin inclination angle, front wheel camber angle, front w...

AI Technical Summary

Problems solved by technology

In the actual car, because the two parameters of front wheel camber and front wheel toe-in are small in adjustment amount, their action process is not obvious, and it is difficult for students to intuitively feel the parameter changes and their effects; The inclination angle is a spatial angle, and the angle forming process is relatively complicated, and its function is difficult to demonstrate through a real vehicle in the classroom, so it is not easy for
