Auto Teaching Equipment . Thetransparentoverallvehicle model Proportion with actual car : 1:1 Attached with Auto Circuit .. Introduction: Usage This instructional car chassis is used for auto driving training, auto repairing for teaching in junior college or vocational school, which is one of the most helpful teaching aid tools. By demonstrating this instructional car chassis model, learners can know about the autos inner mechanic structure and functions, master the structure and principles about auto quickly, and learners can have initial knowledge about sedans. Structure and features We adopt transparent plexiglass to make these car chassis model. The parts inside uses rigid plastic materials and are fixed by screws on the car chassis which is made by high-temperature dried lacquer. Each assembly part is processed by pressing model forming instead of the way of conglutination in the past, which improves the product quality in intensity. The engine assembly is drove by electricity. The speed control device is designed on the oil throttle. The clutch is separated obviously and manipulated flexibly. The crust of cutch is formed by overall dies. The transmission case and different archives of gear wheel are showed by different colors. It is manipulated flexibly and good-looking. The rear axles profile is formed by pressing. The interior main slowdown, different speed is rotated freely. The wheel hub brake is formed by pressing and can be adjusted. The front axle wheel drum can be adjusted, too. The steering device and batteries, fuel tanks, water tanks, the brake pipe can be seen clearly. The circuit is distributed in the front and rear. The Light, wind shutters, panels, and rear light are adopted the transparent plexiglass and formed as overall aesthetics and look like the real car.
