Abstract
An antiskid device (A) mounted to a tread (20) of a tire (2) has a pin (10) and a heat insulating member (11) attached to an end of the pin (10). The pin (10) is made of a material having a higher hardness in a first temperature range not higher than a predetermined temperature and a lower hardness in a second temperature range above the predetermined temperature. The insulating member (11) prohibits heat transfer from the tire (2) to the pin (10).
Claims9
An antiskid device comprising:
- a pin portion formed of a resin having a higher hardness in a first temperature range not higher than a predetermined temperature and a lower hardness in a second temperature range above the predetermined temperature;
- and
- a heat insulating portion provided at one end of the pin portion and formed of said resin mixed with a heat insulating material;
- wherein the pin portion and the heat insulating portion are formed integrally by simultaneous molding.
An antiskid tire having a tread provided with antiskid devices,
- wherein each of the antiskid devices comprises a pin portion formed of a resin having a higher hardness in first temperature range not higher than a predetermined temperature and a lower hardness in a second temperature range above the predetermined temperature, and a heat insulating portion provided at a base end of the pin portion and formed of said resin mixed with a heat insulating material, the pin portion and the heat insulating portion being formed integrally by simultaneous molding.
An antiskid tire having a tread provided with first antiskid devices and second antiskid devices:
- wherein each of the first antiskid devices comprises a pin portion formed of a resin having a higher hardness than the tread in a first temperature range not higher than a predetermined temperature and a lower hardness than the tread in a second temperature range above the predetermined temperature, and a beat insulating portion at a base end of the pin portion and formed of said resin mixed with a heat insulating material, the pin portion and the heat insulating portion being formed integrally by simultaneous molding;
- and
- wherein each of the second antiskid devices comprises a pin made of a rubber having a higher hardness than the tread in the first and the second temperature ranges.
