Light four-wheeled vehicle approximately the size of a passenger motor vehicle with a built-in space for a measuring device for measurement of the grip of the road surface

摘要

The lightweight motor vehicle, with the dimensions of an automobile, has a space to accommodate a measurement unit to measure the gripping qualities of a road surface. The space contains a lever mechanism for at least one measurement wheel at an angle of about 20[deg] to the vehicle longitudinal axis. The axis (7) of the measurement wheel (1) is coupled to at least one force measurement unit (8). The axis is bonded to an axial tapered roller (9) in a force fit, held in a planetary gearing (10).
