Detailed Explanation of Various Automotive Parameters?
1 Answers
The various parameters of a car include: 1. Body Dimensions - Length * Width * Height. Cars are categorized into A00-class (micro cars), A0-class (subcompact cars), A-class (compact cars), B-class (mid-size cars), C-class (large cars), and D-class (luxury cars). 2. Wheelbase. The wheelbase is the distance between the centers of the front and rear axles, measured as the distance between two vertical lines passing through the midpoints of adjacent wheels on the same side of the vehicle and perpendicular to the vehicle's longitudinal symmetry plane. 3. Front/Rear Track. The front/rear track is the distance between the centerlines of the tracks left by the front/rear wheels on the vehicle's supporting plane (generally the ground), i.e., the distance between the centers of the left front and right front wheels. 4. Minimum Ground Clearance. The minimum ground clearance refers to the distance between the ground and the lowest point of the vehicle's rigid components (such as the engine oil pan, fuel tank, or suspension arms) when the vehicle is fully loaded and parked on a level surface. 5. Minimum Turning Diameter. The minimum turning diameter is the larger of the two diameters of the circular tracks made by the outer edges of the front tires when the steering wheel is turned to its limit, causing the vehicle to move in a circular path on a flat surface. 6. Body Structure. Based on the stress distribution and different structures, vehicle bodies can be classified into monocoque (unibody), semi-monocoque, body-on-frame, and space frame structures. 7. Monocoque Body. A monocoque body vehicle does not have a rigid frame; instead, it reinforces areas such as the front, side panels, rear, and floor. Components like the engine, front and rear suspensions, and parts of the transmission system are mounted directly on the body, and the body load is transferred to the wheels through the suspension system.
