VEHICLE BRAKING DEVICE Russian patent published in 1997 - IPC

FIELD: transport engineering; devices to increase road holding capacity of wheels at braking. SUBSTANCE: device has axle 1 connected with wheel hub 2, wheel disk and face plate 5 installed on axle 1 for angular displacement relative to wheel, spring-loaded pins 13 installed in guides 14 and pin extension mechanism made in form of cams 9 mechanically coupled with face plate by fingers 3 located in ring slots 4 of disk. At abrupt application of brakes effort of holding spring is overcome and radial cam forces pins out of guides to bring them in contact with surface of main road.
