3.5.4.3 Verify the required gradeability (25% and 30%) by simple calculation. If necessary, a vehicle of the relevant type may be required for actual testing. 3.5.4.4 When measuring the approach angle, departure angle and longitudinal breakover angle, the rear lower guard shall not be considered. 3.5.5 Definitions and illustrations of approach angle, departure angle, longitudinal breakover angle and ground clearance 3.5.5.1 Approach angle
refers to the maximum angle between the ground plane and the tangent plane of the front wheel tire under static load, so that in front of the front axle of the vehicle, all points of the vehicle are above the tangent plane, and all rigid components on the vehicle (except the pedals) should also be above this tangent plane, see Figure 1. o
3.5.5.2 Departure angle
is the maximum angle between the ground plane and the plane tangent to the rear wheel tires under static load, so that, behind the rearmost axle of the vehicle, all points and rigid parts of the vehicle are located above this plane, see Figure 2. Figure 2
3.5.5.3 Longitudinal breakover angle
is the minimum acute angle formed by two planes perpendicular to the longitudinal center plane of the vehicle, tangent to the front and rear wheel tires, intersecting and contacting the rigid parts of the vehicle chassis (except the wheels) under static load. This angle determines the steepest slope that the vehicle can pass, see Figure 3. Figure 3
3.5.5.4 Ground clearance between the front and rear axles
is the distance between the ground and the lowest point between the two axles, see Figure 4. Axles with multiple axles are regarded as single axles.
3.5.5.5 Ground clearance under axle
GB/T15089--2001
It refers to the distance from the highest point on the arc passing through the center of the wheel tire footprint on a single axle (if it is a double wheel tire, it is the inner wheel tire) and the lowest fixed point of the vehicle to the ground. No rigid part of the vehicle shall extend into the shaded area in the figure (see Figure 5). If necessary, the ground clearance under the axle of several axles can be arranged in order, for example: 280/250/250. Figure 5
