Fig. 6.22. Measuring the height of the control points of the lower part of the car body.
Dimensions H1 and H4 are measured along the wheel rotation axis. Dimensions H2 are measured under the jack platform. Dimensions H5 are measured along the rear axle mounting axis of the vehicle.
Sections 13.1-13.4 provide values for the front axle wheels, and section 13.5 provides values for the rear axle wheels.
