What do the approach angle and departure angle of a car mean?
1 Answers
Approach angle refers to the angle between the ground and the tangent line drawn from the foremost protruding point of the car to the front wheel when the car is fully loaded and stationary. Departure angle refers to the angle between the road surface and the tangent line drawn from the rearmost protruding point of the car to the rear wheel when the car is fully loaded and stationary. Here are the relevant introductions: 1. Approach angle: The approach angle is the maximum angle between the horizontal plane and the plane tangent to the outer edge of the front wheel tire (under 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 less likely the car is to have a contact accident when boarding or disembarking a ferry or during off-road driving, and the better the car's passing performance. 2. Departure angle: The departure angle refers to the angle between the road surface and the tangent line drawn from the rearmost protruding point of the car to the rear wheel when the car is fully loaded and stationary, that is, the maximum angle between the horizontal plane and the plane tangent to the outer edge of the rearmost wheel tire (under static load). Any rigid component fixed to the vehicle behind the rearmost wheel must not be below this plane. It characterizes the car's ability to avoid collision when leaving obstacles (such as hills, ditches, etc.). The larger the departure angle, the better the car's passing performance.
