Title: Motor vehicle wheel antiskid attachment - has diametral rotating spring arm with road contacting antiskid pads
Inventor: LINDBLAD OSKAR LENNART
IPC: B60C27/04
Filed: 1978-11-23
Abstract: The antiskid attachment for motor vehicle wheel tyres rotates with the wheel. The skidding is prevented by gripping pads projecting beyond the tyre surface and the attachment is firmly held and cannot be lost on travelling. The attachment has diametral arms which are connected at the tyre circumference by antiskid pads. These spring arms are held at the wheel hub so that the arms cannot move axially. These arms are free to rotate on the hub when antiskid pads contact the road surface. The arms can also slide in the hub. When the pads come in contact with the road surface they are forced against the tyre, to form a high-friction bridge between the tyre and the road.
