Scientists at Kuban State Technological University have patented a stand for studying the working process of twin wheels of heavy vehicles. The development allows studying tire slippage parameters on different types of road surfaces – from asphalt to dirt roads.
The stand is made in the form of a metal frame with a replaceable contact surface. An axle with test wheels and an axle with contact rollers are installed on a U-shaped bracket. Gyroscopic sensors for longitudinal tilt, yaw angle, and lateral displacement, as well as pulse sensors for wheel rotation, are used for measurements. A freewheel clutch with electromagnetic locking records slippage moments in three planes.
The technical result is the expansion of the stand's functional capabilities. The development can be applied in the automotive and tire industries to test the grip properties of wheels, which will improve the safety and handling of trucks.
