Approach And Departure Angles
Approach angle is the maximum angle of a ramp onto which a vehicle can climb from a horizontal plane without interference. It is defined as the angle between the ground and the line drawn between the front tire and the lowest-hanging part of the vehicle at the front overhang. Departure angle is its counterpart at the rear of the vehicle – the maximum ramp angle from which the car can descend without damage. Approach and departure angles are also referred to as ramp angles. Approach and departure angles are indicators of off-road ability of the vehicle: they indicate how steep obstacles, such as rocks or logs, the vehicle can negotiate according to its body shape alone. See also * Breakover angle * Overhang (automotive) * Ride height Ride height or ground clearance is the amount of space between the base of an automobile tire and the lowest point of the automobile (typically the axle); or, more properly, to the shortest distance between a flat, level surface, and the lowe ...

Overhang (automotive)
Overhangs are the lengths of a road vehicle which extend beyond the wheelbase at the front and rear. They are normally described as front overhang and rear overhang. Practicality, style, and performance are affected by the size and weight of overhangs. Characterization Along with clearance, length of overhangs affects the approach and departure angles, which measure the vehicle's ability to overcome steep obstacles and rough terrain. The longer the front overhang, the smaller is the approach angle, and thus lesser the car's ability to climb or descend steep ramps without damaging the front bumpers. Typically, the rear overhang is larger on rear-wheel drive cars, while the front overhang is larger on front-wheel drive cars. Overhangs in the case of rolling stock are the lengths from the bogie pivots to the ends of the car, or in the case of two axles the distances outside of the wheelbase to the ends of the car.

Off-road
Off-roading is the activity of driving or riding in a vehicle on unpaved surfaces such as sand, gravel, riverbeds, mud, snow, rocks, and other natural terrain. Types of off-roading range in intensity, from leisure drives with unmodified vehicles, to competitions with customised vehicles and professional drivers. Off-roaders have been met with criticism for the environmental damage caused by their vehicles. There have also been extensive debates over the role of government in regulating the sport, including a Supreme Court case brought against the Bureau of Land Management in the United States. Off-road vehicle Travelling over difficult terrain requires vehicles capable of off-road driving such as ATVs. These vehicles have features designed specifically for use in off-road conditions such as extended ground clearance, off-road tires and a strengthened drive-train. Some manufacturers offer vehicles specifically designed for off-road use. Recreational off-roading Some ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breakover Angle
Breakover angle is the maximum possible supplementary angle (usually expressed in degrees) that a vehicle, with at least one forward wheel and one rear wheel, can drive over without the apex of that angle touching any point of the vehicle other than the wheels.Division of the Federal Register, United States: ''The Code of Federal Regulations of the United States of America'', page 447.

SAE J689: Cancelled AUG 2009 Curbstone Clearance, Approach, Departure, and Ramp Breakover Angles--Passenger Car and Light TruckSAE J1100 NOV 2009 Motor Vehicle Dimensions This definition is contingent upon the wheels being in continuous contact with the supporting surface(s). Breakover angle differs from ground clearance, which is the shortest distance between the ground and lowest point on the vehicle. Relevance Breakover angle is a relevant performance metric in many common vehicle scenarios, including: * Off-roading. * Loading a vehicle onto a higher surfa ...

Ride Height
Ride height or ground clearance is the amount of space between the base of an automobile tire and the lowest point of the automobile (typically the axle); or, more properly, to the shortest distance between a flat, level surface, and the lowest part of a vehicle other than those parts designed to contact the ground (such as tires, tracks, skis, etc.). Ground clearance is measured with standard vehicle equipment, and for cars, is usually given with no cargo or passengers. Function Ground clearance is a critical factor in several important characteristics of a vehicle. For all vehicles, especially cars, variations in clearance represent a trade-off between handling, ride quality, and practicality. A higher ride height and ground clearance means that the wheels have more vertical room to travel and absorb road shocks. Also, the car is more capable of being driven on roads that are not level, without the scraping against surface obstacles and possibly damaging the chassis and und ...
