Title: Tyre surface grip test rig - with weighted roller of surface material urged against moving tyre tread
Inventor: SUDBRACK BERNFRIED DR ING
IPC: G01N19/02
Filed: 1979-05-29
Abstract: The surface grip of pneumatic tyres on roads is simulated in the laboratory by using a horizontal cylindrical sample of the road surface material which can slide on vertical guides and is loaded by a weight. A tyre tread is cut from a standard tyre and is passed around the cylindrical sample and around a drive pulley vertically above it. Jets of water or of salt spray soln. to simulate rainy or wintry conditions can be directed between tyre tread and roller. The measurement of the frictional force, produced by braking the sample while keeping the tread speed constant, allows a reliable assessment of the surface grip.
