What is the acceptable approach angle for an SUV?
1 Answers
The approach angle of an SUV is generally greater than 20°. For example, the Audi Q5L has an approach angle of 23°. The ground clearance, approach angle, and departure angle are three parameters that affect a vehicle's off-road capability. The larger these parameters are, the better the vehicle's off-road performance. Specific explanations are as follows: 1. Ground clearance: The distance between the lowest protruding part of the vehicle's chassis and the horizontal ground when the vehicle is fully loaded (with the maximum allowable load mass). The minimum ground clearance reflects the vehicle's ability to pass over obstacles or uneven terrain without collision. 2. Approach angle: When the vehicle is fully loaded and stationary, the angle between the tangent line drawn from the frontmost protruding point of the vehicle to the front wheels and the ground. This is the maximum angle between the horizontal plane and the plane tangent to the outer edge of the front wheel tires (static load). Any rigid component fixed to the vehicle in front of the front axle must not be below this plane. The larger the approach angle, the better the vehicle's ability to pass over obstacles. 3. Departure angle: When the vehicle is fully loaded and stationary, the angle between the tangent line drawn from the rearmost protruding point of the vehicle to the rear wheels and the road surface. This is the maximum angle between the horizontal plane and the plane tangent to the outer edge of the rearmost wheel tires (static load). Any rigid component fixed to the vehicle behind the rearmost wheels must not be below this plane. It indicates the vehicle's ability to leave obstacles (such as small hills, ditches, etc.) without collision. The larger the departure angle, the better the vehicle's off-road capability.
