The car modification Dictionary of approach angle

Approach (APPROACH ANGLE) is in the fully loaded car is stationary, automotive front-end salient points to the front wheel cited tangent and the angle between the ground. Namely, the maximum included angle between the horizontal plane and tangential to the plane of the front tire outer edge (static load), the front axle in any preceding rigid member fixed to the vehicle shall not be in this plane in the bottom. Approach angle greater the car on downhill or cross-country travel, the less prone to "contact" and "knock chin" accident, through the performance of the car, the better.
 
 The departure angle (departure angle) refers to the fully loaded car, when at rest, since the body rear end salient points rearward wheels cited the angle between the tangent line and the road surface, i.e. the horizontal plane and the cutting outer edge of the to last wheel tires of the vehicle (static load) the maximum included angle between the plane, located in the last behind the wheel on a vehicle, any fixed rigid member shall not be below this plane. It is characterized by the car left the hillock, obstructions (such as groove depressions, etc.), the ability to not collide. Departure angle the greater, the car through the better.

    Relative to the approach angle uphill departure angle is applicable when going downhill. The vehicle downhill all the way, the current round has been traveling to the ground, and the rear wheel is still on the ramp, rear bumper will not be on the card in the ramp, the key lies in the departure angle. Departure angle greater the vehicle by the steeper the ramp down, and do not have to worry about the rear bumper is stuck stuck.
